Problems solved by technology

Although the existing flame-retardant coatings can insulate the flame after being applied to the surface of the object, the temperature insulation effect is poor, and the coating is easy to fall off after being baked by the flame, which reduces the fireproof performance.

Abstract

The invention discloses a nano high-efficiency flame-retardant coating for a water supply pipe and a production process of nano high-efficiency flame-retardant coating. The flame-retardant coating comprises the following components in parts by weight: 120-140 parts of a base material, 40-58 parts of a thermal expansion aid, 14-28 parts of aluminum hydroxide, 5-10 parts of a foaming agent, 10-16 parts of flame retardant, 18-26 parts of ammonium carbonate, 8-14 parts of nano inorganic filler, 10-20 parts of a hydroxymethyl cellulose emulsion and 8-14 parts of a 731 dispersant. Due to addition ofthe nano inorganic filler in the base material of the coating, the degree of flame retardance of the base material can be effectively increased; meanwhile, due to addition of the thermal expansion aid in the base material, under a high temperature condition of a fire hazard, under the catalysis function of polyphosphates, dextrin components in the coating can be rapidly expanded and carbonized, then a net-shaped fireproof structure which is not easy to drop off and is capable of retarding flame and insulating heat can be formed, a coating function on a pipe material inside is taken into play,and fire spreading can be retarded; and in addition, at a high temperature, aluminum hydroxide has a heat absorption reaction, so that the temperature of the pipe material is reduced, and combustioncan be alleviated.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant coatings, and in particular relates to a nano-high-efficiency flame-retardant coating for water supply pipes and a production process thereof. 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. Although the existing flame-retardant paint can insulate the flame after being applied to the surface of the object, the temperature insulation effect is poor, and the coating is easy to fall off after being baked by the flame, which reduces the fireproof performance. Contents of the invention [0003] The purpose of the present invention is to provide a nano high-efficiency flame-retardant coating for water supply pipes and its production process, so as to solve the pro...
