Abstract

The invention discloses a nano fire-resistant paint which is composed of the following components in percentage by weight: 80-90% of component A and 10-20% of component B. The component A comprises the following components in parts by weight: 30-50 parts of ethylene-vinyl acetate copolymer, 20-25 parts of nano silicon dioxide, 1-8 parts of assistant and 0.4-0.6 part of mixed solvent. The assistant comprises a wetting agent, an anti-settling agent and a defoaming agent. The mixed solvent comprises propanediol 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 propanediol and 15-20 parts of talcum powder. The invention also discloses a preparation method and application of the fire-resistant paint. The nano fire-resistant paint has the advantages of stable quality, favorable use effect, higher adhesive force and more durable antimicrobial effect.

Description

technical field [0001] The invention relates to a paint, in particular to a nano fireproof paint and its preparation method and application. 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 nano fireproof coating. The second object of the present invention is to provide the preparation method of above-mentioned nano fireproof coating. The third ...
