Problems solved by technology

Most of the insulation walls use porous materials. When a fire occurs, it is easy to cause the fire to expand and cause huge loss of personnel and property. How to improve the fire performance of insulation walls has become the focus of attention.
The effect of general fire retardant coatings on thermal insulation walls is very weak, especially when the walls are damp, the performance of the coatings is greatly reduced

Abstract

The invention relates to the technical field of research, development and production of fireproof coatings and discloses a fireproof coating for thermal insulation walls. The fireproof coating is prepared from components in parts by weight as follows: 30-35 parts of a polyvinyl acetate emulsion, 20-25 parts of polyvinyl alcohol, 18-22 parts of ammonium polyphosphate, 16-20 parts of pentaerythritol, 14-18 parts of melamine resin, 8-12 parts of hexamethylenetetramine, 4-6 parts of chlorinated paraffin, 3-5 parts of a surfactant, 1.3-1.5 parts of glass powder, 0.8-1.0 part of asbestos powder, 0.3-0.5 parts of superfine dispersible nano alumina powder, 0.1-0.3 parts of nano silica and 35-40 parts of water. The fireproof coating has a very low heat conduction coefficient and can improve the thermal insulating property of a thermal insulation material, prevent thermal motion enhancement caused by increased heat conduction coefficient after water absorption and forms a sponge carbonization layer for fire isolation.

Description

technical field [0001] The invention belongs to the technical field of R&D and production of fireproof coatings, and in particular relates to a fireproof coating for thermal insulation walls. Background technique [0002] The thermal insulation material used in the thermal insulation wall has the effect of retarding the transfer of heat flow, and is widely used in the thermal insulation of roofs and walls. Heat insulation materials are divided into three categories: porous materials, heat reflective materials and vacuum materials. The former uses the pores contained in the material itself to insulate heat, because the thermal conductivity of the air or inert gas in the pores is very low, such as foam materials, fiber materials, etc., and heat reflective materials have a high reflection coefficient, which can reflect heat. Gold, silver, nickel, aluminum foil or metal-plated polyester, polyimide film, etc. Vacuum insulation materials use the internal vacuum of the material t...
