Abstract

The invention relates to a preparation method of a low flame coating. The preparation method comprises the steps of preparing paint pulp mixture containing aluminum hydroxide powder, pigment and filler, assistant and water, and then carrying out dispersing and sanding to obtain paint pulp; preparing the low flame coating containing epoxy resin emulsion and paint pulp assistant, and filtering and packaging the mixture to obtain the low flame coating. No organic solvent is added to the low flame coating disclosed by the invention. Therefore, the preparation method is safe, low-toxicity, free of pollution, easy to operate, and simple in process, and has good adhesive force of a paint film, shock resistance, flexibility, good ageing resistance, corrosion resistance, radiation resistance, self-cleaning capability, antistatic property, flame retardant property and the like.

Description

technical field [0001] The invention relates to a preparation method of a low-flame-spread coating, which is used for effectively limiting flame spread and belongs to the field of coatings. 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. The fire retardant coating is coated on the surface of the substrate. In addition to its flame retardant effect, it also has anti-rust, waterproof, anti-corrosion, wear-resistant, heat-resistant, coating toughness, colorability, adhesion, easy-drying and a certain gloss, etc. performance. [0003] Ships, as mobile buildings on oceans and inland rivers, have very high fire safety requirements, and uniform requirements for the safety performance of operating ships are required. The low flame spread performance o...
