Flame-retardant coating for floor

Abstract

The invention provides a flame-retardant coating for a floor. The flame-retardant coating is characterized by being prepared from components in parts by weight as follows: 40-60 parts of an acrylic emulsion, 20-40 parts of a pure acrylic emulsion, 4-8 parts of vermiculite powder, 5-10 parts of superfine dolomite, 8-16 parts of a flame retardant, 0.4-0.8 parts of a wet dispersant, 0.3-0.6 parts ofa levelling agent and 18-24 parts of filler, wherein the flame retardant is mainly prepared from graphene oxide, multi-carbon nanotubes and a carboxymethyl chitosan schiff base derivative. The flame-retardant coating has good thermal insulation and fireproof performance and is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a flame-retardant coating for floors. Background technique [0002] In the decoration industry, the fire protection of wooden floors has always been a concern of consumers. At present, fire retardant coatings on the market are generally divided into two types: intumescent and non-intumescent. Non-intumescent fire retardant coatings achieve fire prevention effects by adding flame retardants. To achieve a good fire prevention effect, they must be painted very thick and Adding a large amount of flame retardants containing halogens, nitrogen, phosphorus, etc., produces a large amount of toxic gases; intumescent fireproof coatings are coatings that expand when heated to form a honeycomb carbonized layer, which isolates the heat of the flame and reduces or slows down the transfer to the substrate. At high temperature, the coating decomposes to release other gases, isolate...

Problems solved by technology

At present, fire retardant coatings on the market are generally divided into two types: intumescent and non-intumescent. Non-intumescent fire retardant coatings achieve fire prevention effects by adding flame retardants. To achieve a good fire prevention effect, they must be painted very thick and Adding a large amount of flame retardants containing halogens, nitrogen, phosphorus, etc., produces a large amount of toxic gases; intumescent fireproof coatings are coatings that expand when heated to form a honeycomb carbonized layer, which isolates the heat of the flame and reduces or slows down the transfer to the substrate. At high temperature, the coating decomposes to release other gases, isolates and dilutes the air, and in addition, a series of physical and chemical reactions of the coating absorb a large amount of heat when it is fire-resistant, thereby retarding the flame and delaying the spread and spread of the flame, providing people with fire extinguishing time, but intumescent fire retardant coatings are mainly solvent-based coatings with high VOC, which can no longer meet the market demand for low VOC
