Technical Field

The invention relates to the technical field of building materials, in particular to anti-radiation putty powder and a preparation method thereof.

Background

With the progress of society, the development of economy and the improvement of modern living standard, the requirement of human beings on the living environment is higher and higher, and people are eagerly provided with a fresh and comfortable living space and working environment. However, not negligible is the radiation of appliances in indoor environments, such as: electric blanket, hair drier, electromagnetic oven, computer monitor and host, mobile phone, television, printer, etc. Although the pollution of electromagnetic radiation is invisible, the harm to our bodies is self-evident. Electromagnetic radiation contamination can affect the nervous system, cardiovascular system, immune system, eye and reproductive systems of the human body. The hazards of electromagnetic radiation can cause human beings to appear: dizziness, headache, fatigue, inattention, hypomnesis, insomnia, palpitation, chest distress, xerostomia, hypoimmunity, cataract, menoxenia, and sexual hypofunction. Therefore, it is urgent to find an effective method for protecting electromagnetic radiation.

The putty powder is a decorative material for leveling wall surface, is made up by using inorganic cementing material as base material, adding adhesive material and other auxiliary agent and adopting fine processing process, and is an indispensable product for coating before painting, and can be applied on priming paint or directly applied on the object to remove the defects of high and low unevenness on the surface of the coated object. The main functions of the coating are to level the wall surface and to adhere the wall surface base layer and the coating, and simultaneously, the coating can prevent the wall surface from peeling, cracking and falling off, and the construction quality can be ensured only if the coating has good plasticity and rheological property, affinity property, compression resistance, wear resistance, good anti-seepage and heat insulation performance and the like. If the radiation-resistant putty powder can be developed, the radiation-resistant putty powder can better play the role of radiation resistance and the role of double insurance, and the harm of radiation to human bodies can be further reduced. Therefore, the development of the anti-radiation putty powder has great practical significance.

However, the putty powder can only shield radiation of radioactive substances, but cannot adsorb radiation of the radioactive substances, does not contain other auxiliary raw materials, and cannot form a conductive film to realize high transmittance and antistatic effect.

Therefore, it is very important to develop a radiation-resistant putty powder with remarkable radiation-resistant effect, good comprehensive performance, excellent water resistance, crack resistance, compressive strength, performance stability and environmental protection performance.

Comparative example 6

A radiation resistant putty powder, its preparation raw material and its preparation method are basically the same as example 1, except that 4- (2-furyl) -1-buten-4-ol/glycidyl methacrylate/1-allyl-3-methyl imidazole chloride/phenyl vinyl sulfone/3- (methacryloyloxy) propyl trimethoxy silane copolymer is prepared without adding 4- (2-furyl) -1-buten-4-ol.

The radiation-resistant putty powders obtained in the above examples 1-5 and comparative examples 1-6 were tested, the test results are shown in Table 1, and the test methods are shown in JG-T3049-1998; according to the relevant provisions of MIL-STD-285:1956, namely the electromagnetic shielding environment attenuation method for electronic tests, the method is carried out in a wave-absorbing darkroom built according to the standard, equipment such as a signal source, a frequency spectrograph, a transmitting and receiving antenna and the like is needed, and the radiation resistance of the putty powder is tested by adopting medium wave, short wave, ultrashort wave and microwave through a simulation method test.

As can be seen from Table 1, the radiation-resistant putty powder disclosed by the embodiment of the invention has better water resistance and radiation resistance, and has larger adhesive force, which is the result of the synergistic effect of the components. The radiation resistance of the radiation-resistant putty powder can be improved by adding the hydrophilic polypyrrole, the fullerene-based carbon quantum dots and the metal organic framework with the carboxyl.
