Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below. It is apparent that the specific details set forth in the following description are merely exemplary of the invention, which can be practiced in many other embodiments that depart from the specific details disclosed herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

The invention provides clay for children to play, wherein the clay formula adopts non-toxic and environment-friendly materials, and does not contain components harmful to human bodies, so that children do not have anaphylactic reaction during playing, and the clay is healthy and environment-friendly. The clay also contains antibacterial agent, which can inhibit the growth of bacteria, and the clay is not easy to mildew and can be used for a long time.

In one embodiment, the clay formulation comprises, in weight percent: 10-25% of polyvinyl alcohol, 1-5% of carrot pigment, 15-30% of deionized water, 5-17% of humectant, 0.4-8% of sodium hexametaphosphate, 0.3-3% of dimethyl polysiloxane, 0.1-2% of sodium tripolyphosphate, 10-15% of foam powder, 0.5-5% of titanium tetrachloride, 0.6-6% of anthocyanin, 3-7% of thickening agent and 3-6% of antibacterial agent.

The deionized water can be replaced by pure water or distilled water which is commonly used in life, and the deionized water does not contain mineral ions basically so as to avoid the influence on the quality of the clay caused by the reaction with other components in the formula.

The method can be used for preparing orange colored clay, the pigment of the clay with other colors is only required to be replaced, and other components are not changed, namely, the anthocyanin and the carrot pigment are replaced by the pigment with other colors. The anthocyanin can provide various colors for the clay, and has active molecules with health care functions of reducing the activity of enzyme, resisting variation and the like, so that the clay has stronger antibacterial action.

The sodium hexametaphosphate has strong hygroscopicity, and can gradually absorb moisture when exposed in the air to form a sticky substance. When children play with the clay, the clay can absorb moisture on the hands of the children and moisture in the air in a proper amount, so that the clay can continuously keep stronger softness, and the playing experience of the children is good.

The humectant may be one or more of glycerol, sorbitol, propylene glycol. The humectant of the embodiment uses glycerin, which can make the clay not easy to dry, and can keep the humidity for a long time, so that the clay is easy to deform and shape. Moreover, glycerin has the function of moistening skin, and is beneficial and harmless to the skin of children when playing clay.

The thickener is composed of one or more of silica gel, sodium bentonite, organic bentonite and diatomite. The thickener of this example has a silicone gel composition, and can greatly enhance the flexibility of clay, which can be easily kneaded into any shape.

The antibacterial agent is vanillin or ethyl vanillin compound. The antibacterial agent of the embodiment is vanillin, also known as vanillin, and vanillin has a strong antibacterial effect and can inhibit the growth of many bacteria, so that the clay is not easy to mildew after being used for a long time.

The foaming powder can be hollow foaming microspheres, and when the foaming powder is heated, the hollow foaming microspheres are fermented, so that the clay becomes fluffy, the volume is increased, and the hand feeling is softer.

The invention also provides a preparation method of the clay for children to play, which at least comprises the following processing steps:

s1: pouring deionized water into a reaction kettle, pouring polyvinyl alcohol, anthocyanin and carrot pigment into the reaction kettle, heating in water bath to 45 ℃, adding a thickening agent into the reaction kettle, and slowly stirring at the speed of 2-4 r/s for 5-10min until the materials are completely dissolved in the deionized water to form the color sol.
