Coating structure with flame retardant and thermal insulation functions

Abstract

The invention relates to the technical field of functional coatings and aims to provide a coating structure with flame-retardant and heat-preserving functions. The coating structure with flame-retardant and heat-preserving functions includes a concrete slab or cement slab as a substrate, and n layers of flame-retardant and heat-preserving slurry layers are also covered on the surface of the substrate, where n≥1. The thermal conductivity of the present invention can reach 0.15W / m·K or below, and the thermal conductivity of ordinary thermal insulation coatings is about 0.3W / m·K; the adhesion can reach national standard level 1 or above; the coating is non-combustible at high temperatures. Therefore, the flame-retardant and heat-retaining functional coating structure of the present invention has high heat-retaining and flame-retardant characteristics. The cost of raw materials is low, the preparation process is simple, and the adhesion of the coating is good; the coating structure uses conventional concrete slabs or cement slabs as substrates, and is easy to realize large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, in particular to a coating structure with flame-retardant and heat-preserving functions. Background technique [0002] Making full use of and saving energy is a major issue in the sustainable development of human beings, and the use of suitable thermal insulation materials is an effective measure to solve this issue. The current thermal insulation coating is mainly sprayed with polyurethane foam and other polymers. With the rapid development of my country's polyurethane industry in recent years, sprayed polyurethane rigid foam has been identified as the preferred material for building thermal insulation and energy efficiency. And it has received extensive attention in the industrial and architectural fields. However, although polyurethane foam insulation material has excellent thermal insulation performance, its main component is organic matter, which is not resistant to aging, and is...

Problems solved by technology

However, although polyurethane foam insulation material has excellent thermal insulation performance, its main component is organic matter, which is not resistant to aging, and is flammable. It is easy to cause serious safety problems such as fire when used on a large area of ​​building surface. Therefore, it is necessary to develop a Insulation coating with both thermal insulation performance and flame retardant effect to improve safety performance
