Novel thermal insulation material

Abstract

The invention discloses a novel thermal insulation material, which is prepared from the following materials by mass: 20-30 parts of diatomaceous earth, 12-16 parts of a urea-formaldehyde resin, 30-35parts of polyurethane, 7-9 parts of magnesium oxide, 20-25 parts of alkali-free glass fiber, 12-14 parts of expanded perlite powder, and 10-12 parts of deionized water. According to the present invention, the thermal insulation material has advantages of low thermal conductivity, good thermal insulation property, good thermal insulation effect, low water absorption rate, good chemical stability, good vibration resistance and good environmental protection performance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel thermal insulation material. technical background [0002] Building thermal insulation is an important aspect of saving energy, improving the living environment and using functions. Building energy consumption generally accounts for 30-40% of the total energy consumption of human beings, most of which are heating and air conditioning energy consumption, so building energy conservation is of great significance. And because the thermal insulation coating uses water as the dilution medium and does not contain volatile organic solvents, it is harmless to the human body and the environment; its production cost is only about 1 / 5 of similar foreign products, and it is a new type of thermal insulation coating. Coatings have the advantages of good economic benefits, energy saving and environmental protection, heat insulation effect and easy construction, and are more a...
