In case of conflict, the present specification, including definitions, will control.

The term "prepared from …" as used herein is synonymous with "comprising". The terms "comprises," "comprising," "includes," "including," "has," "having," "contains," "containing," or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.

The conjunction "consisting of …" excludes any unspecified elements, steps or components. If used in a claim, the phrase is intended to claim as closed, meaning that it does not contain materials other than those described, except for the conventional impurities associated therewith. When the phrase "consisting of …" appears in a clause of the subject matter of the claims rather than immediately after the subject matter, it defines only the elements described in the clause; other elements are not excluded from the claims as a whole.

When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or as a range of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when a range of "1 to 5" is disclosed, the described range should be interpreted to include the ranges "1 to 4", "1 to 3", "1 to 2 and 4 to 5", "1 to 3 and 5", and the like. When a range of values is described herein, unless otherwise stated, the range is intended to include the endpoints thereof and all integers and fractions within the range.

The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. "optional" or "any" means that the subsequently described event or events may or may not occur, and that the description includes instances where the event occurs and instances where it does not.

Approximating language, as used herein throughout the specification and claims, is intended to modify a quantity, such that the invention is not limited to the specific quantity, but includes portions that are literally received for modification without substantial change in the basic function to which the invention is related. Accordingly, the use of "about" to modify a numerical value means that the invention is not limited to the precise value. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. In the present description and claims, range limitations may be combined and/or interchanged, including all sub-ranges contained therein if not otherwise stated.

In addition, the indefinite articles "a" and "an" preceding an element or component of the invention are not intended to limit the number requirement (i.e., the number of occurrences) of the element or component. Thus, "a" or "an" should be read to include one or at least one, and the singular form of an element or component also includes the plural unless the stated number clearly indicates that the singular form is intended.

In order to solve the above problems, a first aspect of the present invention provides an antibacterial and antiviral condom, the surface of which is provided with a silicone coating; the preparation raw materials of the organic silicon coating comprise organic silicon quaternary ammonium salt and water.

In some preferred embodiments, the condom is made of polyurethane or natural latex.

In some preferred embodiments, the weight ratio of the quaternary ammonium silicone salt to water is 1: (8-35).

In some preferred embodiments, the silicone quaternary ammonium salt is selected from one or more of dimethyloctadecyl [3- (trihydroxysilyl) propyl ] ammonium chloride, dimethyloctadecyl [3- (trimethoxysilyl) propyl ] ammonium chloride, N-dimethyl-N-octadecylaminopropyltrimethoxysilane quaternary ammonium salt; further preferably, the organosilicon quaternary ammonium salt is dimethyl octadecyl [3- (trihydroxysilyl) propyl ] ammonium chloride or octadecyl dimethyl [3- (trimethoxysilyl) propyl ] ammonium chloride.

Dimethyloctadecyl [3- (trihydroxysilyl) propyl ] ammonium chloride, as used herein, is available from Syngnan chemical (Shanghai) Co., Ltd. Dimethyloctadecyl [3- (trimethoxysilyl) propyl ] ammonium chloride is DC-5700, produced by Dow Corning, USA.

The inventors have found, through intensive studies, that both dimethyloctadecyl [3- (trihydroxysilyl) propyl ] ammonium chloride and octadecyldimethyl [3- (trimethoxysilyl) propyl ] ammonium chloride can provide excellent and lasting antibacterial effects to condoms, and can improve the lubricity of condoms, the reason is that the two organosilicon quaternary ammonium salts are attached to the surface of the condom due to electrostatic attraction, long carbon chains in the compounds can penetrate into the interior of a polymer structure, the bonding force between the compounds and a base material is improved, the compounds can be condensed under specific conditions to crosslink to form a protective film on the surface of the base material, the protective film can interact with germs, viruses and the like to disturb normal life activities of the condom, has antibacterial and antiviral effects, has certain hydrophilicity, and improves the lubricating effect of the condom.

In a second aspect of the present invention, there is provided a method for producing an antibacterial and antiviral condom as described above, comprising the steps of:

a. mixing organosilicon quaternary ammonium salt and water in a water bath tank to obtain a coating;

b. putting the condom into a water bath tank for soaking;

c. and taking out the condom, drying and packaging.

In some preferred embodiments, the weight ratio of the quaternary ammonium silicone salt to water is 1: (8-35).

In some preferred embodiments, the soaking temperature in the step b is 42-62 ℃.

The inventor has found in long-term practice that the bonding activity of the organosilicon quaternary ammonium salt and the base material is excited under heating, so that the production efficiency is greatly improved, and the antibacterial and antiviral effects are more durable, but outside the preferred temperature range, the production efficiency and the lasting effect are difficult to be improved simultaneously.

In some preferred embodiments, the soaking time in the step b is 12-28 min.

The inventor finds that the production efficiency and the persistence can be balanced within a certain time range, and particularly for condoms made of natural latex materials, the reaction of an organosilicon compound and a base material needs a long time and must be strictly controlled to ensure excellent resistance and persistence.

In some preferred embodiments, the amount of the quaternary ammonium silicone salt is 2.5 to 5.5 wt% of the condom.

The inventor finds that the organosilicon quaternary ammonium salt is bonded with the surface of the condom, so that the antibacterial and antiviral active ingredients are saturated on the substrate within a certain dosage range, and the ineffective ingredients in water are increased along with the increase of the dosage, thereby causing the waste of raw materials.

In some preferred embodiments, the coating has a pH of 4.5 to 6.5.

In some preferred embodiments, the pH of the coating is adjusted by adding citric acid, acetic acid, hydrochloric acid.

In the research and development process of the inventor, the organosilicon quaternary ammonium salt can greatly improve the persistence within a certain pH range, and the reasons are that the dehydration condensation of organosilicon compounds which are free in water under the condition of peracid or overbase is intensified, so that the protective film on the surface of the condom is incomplete, the binding force is poor, the antibacterial and antiviral effects are reduced, the condensation reaction rate of the organosilicon compounds under the condition of weak acid and weak base and the adsorption rate of the organosilicon compounds on the surface of the condom are balanced, and the persistence is improved. In addition, since the condom is in contact with the skin and vaginal mucosa, discomfort to the skin or mucosa can be reduced when the surface is weakly acidic.
