Problems solved by technology

In the traditional flame retardant protective coating, the adhesion between the flame retardant protective coating and the surface of rubber and plastic products is only achieved by the polar polymer in the flame retardant protective coating. The addition of such additives will seriously reduce the adhesion between the coating and the surface of rubber and plastic products and cause delamination and cracking.

Abstract

The invention discloses a rubber and plastic product flame-retardant protective coating and a preparation method thereof. The protective coating comprises the following components by mass: 100 parts of a polar polymer, 0.5-20 parts of two-dimensional nano filler, 5-50 parts of flame retardant, 0.01-10 parts of amine compound, 1-50 parts of polyphenol compound and 0.01-10 parts of polyvalent metalsalt. The preparation method comprises the following steps: 1) adding the two-dimensional nano-filler, the flame retardant, the amine compound, the polyphenol compound and the polyvalent metal salt into a solvent A, and performing a reaction under certain conditions to perform coating modification on the two-dimensional nano-filler and the flame retardant to obtain dispersion liquid A; 2) dispersing the polar polymer in a solvent B under certain conditions to obtain a dispersion liquid B, the solvent A and the solvent B being the same or being mutually soluble; and 3) mixing the dispersion liquid A and the dispersion liquid B under certain conditions to obtain the flame-retardant protective coating which can be brushed on the surfaces of expanded polystyrene thermal insulation foam, staticrubber products and the like to form a flame-retardant protective coating.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant polymers, and in particular relates to a flame-retardant protective coating for rubber and plastic products and a preparation method thereof. Background technique [0002] Rubber and plastic products are ubiquitous in human life. While bringing great convenience to people's life, their flammability has brought serious safety hazards to human production and life. Therefore, the development of flame-retardant polymer materials has become a An important topic in the field of polymers. [0003] At present, the most commonly used polymer flame retardant technology is to add flame retardants to the polymer matrix. Since the vast majority of flame retardants are highly polar, and most polymers are non-polar or weakly polar, resulting in poor compatibility with the polymer matrix, uneven dispersion and surface migration will occur during use and other problems; and most flame retardants want to ...
