Abstract

The invention discloses an environment-friendly fireproof coating and a preparation method thereof. The environment-friendly fireproof coating is prepared from the following components in parts by weight: 30-40 parts of cellulose acetate, 10-15 parts of ammonium polyphosphate, 8-10 parts of melamine, 8-10 parts of primary dodacyl mercaptan, 5-8 parts of silicon carbide, 3-5 parts of zinc borate and 2-3 parts of azodiisobutyronitrile. The prepared environment-friendly fireproof coating has high fireproof performance. Moreover, due to the fireproof coating with the advantages of low cost and excellent performance, a base material can be prevented from coming into contact with air, transfer of flame temperature to a protected base material can be delayed, and the combustion rate is reduced.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an environment-friendly fireproof coating and a preparation method thereof. Background technique [0002] Coatings can be coated on the surface of objects by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. With the continuous progress of human society, the requirements for coatings with different properties are also increasing, and the demand for fireproof coatings is also increasing. Existing coatings containing flame-retardant substances such as halogens will not only deteriorate the physical properties of the coated object, but also pollute the environment. Therefore, fireproof materials can be used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated object, can play a role in retarding the speed of flame spread, and can improve the fire resistance limit of the coated objec...
