Problems solved by technology

[0003] Anti-radiation materials have become a major topic in today's materials science. At present, most of them use the traditional method of adding barite barium sulfate to concrete and cement and applying it to the wall or using composite coating materials containing heavy metals. Anti-radiation effect, but these materials only shield electromagnetic waves, electromagnetic waves will inevitably reflect and cause secondary pollution; and also have defects such as difficult construction, poor corrosion resistance, and poor adhesion, so they are widely used in people's daily life. less

Abstract

The invention discloses an anti-radiation coating. The anti-radiation coating is prepared from, by mass, 30-40% of acrylic emulsion, 0.5-1.5% of graphene, 0.1-0.5% of nano-silver, 15%-25% of dispersing agent, 0.5%-0.8% of alcohol ester-12, 0.5-1% of hydroxypropyl methyl cellulose, 3-5% of pigment and filler, 0.1-0.3% of antifoaming agent and the balance water. According to the anti-radiation coating, the novel materials graphene and nano-silver are introduced, and the application range of a nano material in the coating field is widened. The function of absorbing and shielding electromagnetic waves is achieved. In addition, the anti-radiation coating has the functions of resisting oxidization, preventing corrosion, resisting bacteria, killing bacteria and the like on the premise of keeping good adhesive force, and is an excellent-performance anti-radiation water-based coating for building inner walls and electronic products.

Description

technical field [0001] The invention belongs to the technical field of radiation-resistant coatings, and more specifically relates to a water-based coating with antibacterial, anti-corrosion and anti-oxidation functions. Background technique [0002] With the popularization of electrical appliances such as microwave ovens, refrigerators, copiers, mobile phones, and computers, the coverage of electromagnetic radiation has penetrated into all aspects of human life. While fully enjoying the convenience and comfort of the electrified age, people are increasingly feeling the harm of electromagnetic radiation. In my country, 800,000 to 1.2 million babies are born with defects every year, and electromagnetic radiation has been proved to be one of the main causes of defects in babies; the World Health Organization also believes that cancer, behavioral changes, memory loss and loss, neurasthenia Diseases such as leukemia, cardiovascular disease, and decreased immune function are all r...
