Fireproof coating and preparation technology thereof

Abstract

The invention discloses a fireproof coating and a preparation technology thereof. The fireproof coating is prepared from, in parts by weight, a film forming agent, inorganic hollow filler, an acid donor, a carbon donor, a foaming agent, a synergist, a solvent, an adhesive, an additive, a catalyst, a carbonizing agent, epoxy resin, cellulose ether, expanded vermiculite, magnesium hydroxide, sodiumsilicate, dimethicone, isobutyl ketone, chlorinated paraffin, butyl latex, a thickener, a defoaming agent, an antibacterial agent, water, glass beads, a pigment, ammonium polyphosphate and expanded graphite. The preparation method comprises the steps as follows: color paste preparation, binder preparation and coating preparation. The fireproof coating has the advantages of being environmentally friendly, high in flame-retardant efficiency and the like and has high adhesion, and a cured product has excellent chemical corrosion resistance, heat resistance, acid and base resistance and good electrical insulating property; the coating has excellent sealing performance, the flame-retardant component cannot migrate to a coating surface, and the coating is low in preparation cost, high in practical value, good in film forming performance, wide in application range and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fireproof coating and a preparation process thereof. Background technique [0002] Coating refers to the general term for materials that are applied to the surface of objects and can form a tough protective film. Architectural coatings are an important category of coatings. In my country, they are generally used for interior walls, exterior walls, ceilings, floors, and toilets of buildings. Coatings are called architectural coatings. Architectural coatings have the functions of decoration, protection and habitability improvement. Different types of protected objects have different requirements for protection functions. For example, the indicators required for indoor and outdoor painting are very different. Some buildings have special requirements for mildew resistance, fire prevention, thermal insulation, corrosion resistance, etc. Due to the disadvantages of poor adhesion,...

AI Technical Summary

Problems solved by technology

Due to the disadvantages of poor adhesion, poor weather resistance, poor water resistance and easy falling off of the existing fireproof coatings, the fireproofness of the fireproof coatings will decrease as time goes by, until the fireproof performance is lost. At the same time, the existing fireproof coatings State-of-the-art fire retardant coatings have complex formulas and high costs, and some products have poor fire resistance and are easy to dry and crack, affecting use

China has a vast territory, and there is a large difference in climate and temperature between east, west, north and south. Some fire retardant coatings are suitable for the south, and some fire retardant coatings are suitable for the north. Most fire retardant coatings have poor frost resistance and incomplete functions.
