Abstract

The invention provides a thermal insulation and fireproof coating and a preparation process thereof. The heat insulation and fireproof coating provided by the present invention is a composite coating, including 2 to 8 layers of coatings, each layer of coating is formed from materials containing modified resins, defoamers, nanoparticles and solvents, and is formed from the bottom layer to the surface layer , the mass ratio of modified epoxy resin to modified phenolic resin in each coating layer ω x Gradually decrease to form a gradient composite coating. The obtained overall coating has strong bonding force, good insulation, heat insulation and fire resistance, and is light in weight, and can have a better protective effect on fire fighting equipment.

Description

technical field [0001] The invention relates to the technical field of fireproof materials, in particular to a heat-insulating fireproof coating and a preparation process thereof. Background technique [0002] Heat insulation and fireproof materials are the most commonly used materials in the field of fire protection. Firefighting equipment such as fire helmets and oxygen cylinders must use heat insulation and fireproof materials. The traditional method of flame retardant and heat insulation focuses on the material itself, mostly made of leather composite materials, Kevlar composite materials, modified carbonate (PC) and polyetherimide silicone, carbon fiber reinforced epoxy resin, light alloy and other materials. Oxygen tanks, helmets and other fire fighting equipment. Although these materials themselves have the characteristics of high strength and high toughness, the temperature conditions of the fire scene are complex, and fire-fighting equipment even needs to withstand...
