Abstract

The invention discloses phosphate-radical-intercalated layered-like hydroxide containing zinc, aluminum and tin, a preparation method thereof and application thereof in a flame retardant material. Thephosphate-radical-intercalated layered-like hydroxide containing zinc, aluminum and tin is prepared and compounded, as a char-forming catalyst and a flame retardant, with zinc chloride, acrylamide, acrylic acid and epoxy acrylate to prepare an epoxy acrylate intumescent flame retardant material containing phosphorus, nitrogen, zinc, aluminum and tin, with the material being a low-additive-contenthighly flame retardant acrylate transparent material. A uniform porous charcoal foam layer is generated when phosphorus and a metal Lewis acid are combined to catalyze EA coating combustion in a synergistic manner, thus playing roles of oxygen isolation, heat insulation, smoke suppression, molten drop preventing, and the like, improving flame retardant performance of an epoxy acrylate flame retardant material and improving mechanical performance of the epoxy acrylate flame retardant material. The preparation method is simple and cheap. The hydroxide and the material can be used for the fieldof decorative surface type fireproof flame retardant coating for wooden furniture and ancient wood buildings, and have wide market prospects.

Description

technical field

[0001] The invention belongs to the technical field of epoxy acrylate flame-retardant materials, and in particular relates to a zinc-aluminum-tin-containing phosphate-intercalated layered hydroxide, a preparation method thereof, and an application thereof in flame-retardant materials. Background technique

[0002] Transparent fireproof coating is a type of decorative fireproof coating developed based on the ability to maintain the appearance of the substrate and meet the needs of fire prevention. It is used to protect the surface of ancient buildings, living furniture and fabric decorations without changing their appearance. Appearance and color, it can expand in case of fire and form a uniform and dense honeycomb or spongy carbon foam layer, which has a good protective effect on combustibles and prevents them from being damaged by fire. Important role, has a huge market prospect. Compared with urea-formaldehyde and melamine resins, acrylate resins have the ...
