Abstract

The invention relates to a production technology of an expansion-type transparent fire-retardant coating, which comprises the following steps: mixing ammonium dihydrogen phosphate, formaldehyde, pentaerythritol, urea, triethanolamine and sodium hydroxide according to a certain proportion to prepare a component A; mixing tripolycyanamide, formaldehyde and borax according to a certain proportion to prepare a component B; and mixing the component A and the component B with the weight portion of 1:1-2 to obtain the expansion-type transparent fire-retardant coating. The invention has the advantages of low product cost and favorable fire resistance.

Description

technical field [0001] The invention belongs to the field of paint, and in particular relates to a production process of an intumescent transparent fireproof paint. technical background [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. The fire retardant coating is coated on the surface of the substrate. In addition to its flame retardant effect, it also has anti-rust, waterproof, anti-corrosion, wear-resistant, heat-resistant, coating toughness, colorability, adhesion, easy-drying and a certain gloss, etc. performance. [0003] Combustion is a rapid and violent oxidation reaction with flames. The reaction is very complicated. Three conditions must be met at the same time for the generation and progress of combustion, namely, combustible substances, combustion aids (...
