Abstract

The invention discloses a fireproof coating, comprising the following components in percentage by weight: 80-90% of component A and 10-20% of component B, wherein the component A comprises the following components in parts by weight: 30-50 parts of an ethylene-vinyl acetate copolymer, 20-25 parts of a tinting pigment, 1-8 parts of an assistant and 0.4-0.6 part of a mixed solvent; the assistant comprises a wetting agent, an anti-settling agent and a defoaming agent; the mixed solvent comprises propylene glycol and butyl acetate; the component B comprises the following components in parts by weight: 15-20 parts of cobalt naphthenate, 10-20 parts of melamine pyrophosphate, 20-30 parts of propylene glycol and 15-20 parts of talcum powder. The invention also discloses a preparation method of the fireproof coating. The fireproof coating disclosed by the invention is stable in quality, and good in using effect, and simultaneously has good impact resistance, good artificial ageing resistance and strong adhesive force when having an excellent fireproof effect.

Description

technical field [0001] The invention relates to a paint, in particular to a fireproof paint and a preparation method thereof. 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. [0003] Existing fireproof coatings generally have excellent fireproof effects, but other effects, such as impact resistance, artificial aging resistance, adhesion, etc., are poor, thereby affecting their service life. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the first purpose of the present invention is to provide a kind of fireproof coating. The second object of the present invention is to provide the preparation method of the above-mentioned fireproof coating. [0005] Technical solution: In...
