Problems solved by technology

As a result, the physical and chemical performance indicators and fire resistance of the fireproof finish coatings on the market are not good, and the raw materials used in some coatings are not environmentally friendly, and high concentrations of organic volatile compounds (VOCs) will be produced when they are burned in a fire, and even black out. smoke, which is very harmful to fire victims and rescuers

Abstract

The invention discloses an environment-friendly wall decoration fireproof coating, comprising ceramic fiber, vermiculite, perlite, fine asbestos, borax, mica powder, aliphatic waterborne polyurethane, a film-forming agent, a foaming agent and deionized water, wherein the foaming agent consists of a thermoplastic acrylic resin type polymer, sodium dodecyl benzene sulfonate, ammonium borate, ammonium polyphosphate and deionized water. The raw materials for preparing the coating disclosed by the invention are environment-friendly, have good fireproof performance, cannot deform easily, are high in strength, and cannot fall off and bulk; and preferably, the foaming agent is environment-friendly and nontoxic and has a reasonable formula, so that in the case of fire, the foaming agent expands to generate foams quickly to form a compact sponge-shaped expansion foam layer with a good heat-insulating property, combustible base materials can be protected more effectively, black smoke cannot be generated, and the concentration of organic volatiles is extremely low, which is beneficial for the health of sufferers and rescuers in the fire disaster. The preparation method disclosed by the invention is simple and is easy to operate, and the environment-friendly wall decoration fireproof coating is convenient in construction and firm in adhesion, and cannot crack to ensure that a wall body has a long service life.

Description

technical field [0001] The invention belongs to the technical field of architectural paint and its preparation, and in particular relates to an environment-friendly fireproof paint suitable for wall decoration. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. According to different purposes and objects of use, it can be divided into: decorative fireproof coatings, cable fireproof coatings, steel structure fireproof coatings, prestressed concrete floor fireproof coatings, etc. Among them, decorative fire retardant coatings are getting more and more attention in the architectural coatings industry. But at present, the fireproof coatings for decorative walls pay more attention to the decorative effect, and the fireproof effect is not ideal. [000...
