Fireproof coating for floor

Abstract

The invention provides fireproof coating for a floor. The fireproof coating for the floor is characterized in that the coating is prepared from the following ingredients, in parts by weight: 40-60 parts of acrylic emulsion, 20-40 parts of silicone-acrylic emulsion, 4-8 parts of vermiculite powder, 5-10 parts of superfine dolomite, 8-16 parts of flame retardant, 0.4-0.8 part of wetting dispersing agent, 0.3-0.6 part of leveling agent and 18-24 parts of filler, wherein the flame retardant is mainly prepared from nano silicon dioxide, polyalcohol phosphate ester and a silane coupling agent. The fireproof coating has the good heat 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 fireproof 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, isolates and ...

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
