Problems solved by technology

[0004] However, the fireproof coatings in the prior art have complex formulas, high cost, and some products have poor fireproof performance. They are easy to dry and crack after long-term exposure to light, and finally fall off from the surface of the substrate, affecting the normal protective effect of the coating.

Abstract

The invention discloses a fireproof paint, which comprises following raw materials: polycarbonate, a charring agent, zinc borate, cellulose ether, pentaerythritol, glass fibers, a solvent, a curing agent, and a light stabilizer. The invention also discloses a preparation method of the fireproof paint. The preparation method comprises the following steps: step one, mixing polycarbonate, zinc borate, ammonium polyphosphate, glass fibers, a curing agent, and a solvent, evenly stirring, and grinding the mixture at a high speed to obtain color paste; and step two, mixing cellulose ether, a charringagent, pentaerythritol, and a light stabilizer, evenly mixing, adding the mixture into the color paste obtained in the step one, and carrying out high speed dispersion to obtain the fireproof paint.The fireproof performance is obviously improved, and moreover, the fireproof paint has an excellent performance on resisting coldness and freezing, is resisting to cracking and falling evenly under great temperature difference and long term light irradiation, is resisting to cracking and peeling under a dry or moisture condition, is chemically stable, can protect a flammable basic material for a long term, and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to a fireproof coating and a preparation method thereof. Background technique [0002] With the extensive application of organic synthetic materials, their flammability has become increasingly prominent. Flame-retardant organic polymers containing halogens often lead to deterioration of physical properties of materials, shortened service life, and increased prices. The method of coating fireproof paint on its surface for fireproof protection can not only maintain the excellent performance of the original organic synthetic material, but also be economical and applicable. The application of fire retardant coatings on organic synthetic materials also has broad prospects. In addition, ordinary steel loses its structural strength when heated to about 540°C. Concrete structures are also prone to cracking and disintegration under the action of high-temperature flames. Theref...
