Environment-friendly resin non-combustible thermal insulation material and preparation method thereof

Abstract

The invention relates to an environment-friendly resin non-combustible thermal insulation material and a preparation method thereof. The environment-friendly resin non-combustible thermal insulation material is prepared from the following raw materials: polyester polyol kR-3550, polyester polyol RP-3940, polyether polyol, clay, silicone oil, a trimerization catalyst, aluminum hypophosphite, melamine cyanurate, urea, tris(2-carboxyethyl) phosphine, purified water and isocyanate. The thermal insulation material is prepared by all-water foaming; the all-water foaming is different from the traditional physical F11 and 141B; water is used as a foaming agent for chemical reactions, and reacts with isocyanate in the foaming process to generate urea and release CO2 at the same time; the released CO2 remains in the foam holes to play a role in foaming, the amount of the released CO2 can be controlled by changing the amount of water in the process of preparing the hard foam so as to obtain foambodies with different densities and hardness, the CO2 is non-combustible and non-toxic, and the potential value ODP of ozone consumption is zero.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to an environmentally friendly resin non-combustible thermal insulation material and a preparation method thereof. Background technique [0002] Insulation material is a new type of building material that integrates decoration and heat preservation. Due to the large number of micropores inside it, compared with solid bricks, the thermal conductivity of the brick body is greatly reduced, and the thermal insulation performance is enhanced. At the same time, surface treatment such as glazing on the brick body can be performed. After that, no other wall treatment is required, and it has the characteristics of light weight, heat insulation, heat preservation, and sound absorption, which is of great significance to saving energy and promoting the sustainable development of the country. [0003] At present, thermal insulation materials mainly achieve the pu...

Problems solved by technology

[0004] The main materials used for thermal insulation in the prior art are polyurethane foam and phenolic foam, but polyurethane foam is not flame-retardant, and produces a large amount of falling matter and a large amount of smoke when burning. Phenolic foam has good flame-retardant properties, but the The foam has no strength, is easy to pulverize, and the density is too high
