Environmentally-friendly thermal insulation material

Abstract

The invention relates to an environmentally-friendly thermal insulation material, which comprises, by mass, 25-35% of diatomaceous earth, 14-18% of basalt fiber, 7-11% of an epoxy resin, 12-14% of aluminum hydroxide, 3-7% of quartz sand, 3-8% of gypsum, 1-4% of latex, 3-6% of perlite, and the balance of silicone-acrylate emulsion. According to the present invention, the prepared product is environmentally friendly and harmless, meets the clean and environmental protection requirements, and is not added with harmful substances, and the thermal insulation performance of the material is not affected.

Description

1. Technical field [0001] The invention relates to a new type of material, in particular to an environment-friendly heat insulation material. 2. Background technology [0002] 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 air or inert gas in the pores is very low, such as foam materials, fiber materials, etc.; heat reflective materials have a high reflection coefficient and can reflect heat, such as Gold, silver, nickel, aluminum foil or metal-plated polyester, polyimide film, etc. Vacuum insulation materials use the internal vacuum of the material to block convection and insulate heat. The aerospace industry has strict requirements on the weight and volume of the insulation materials used, and often requires them to have sound insulation, vibration reduction, and corrosion resistan...

Problems solved by technology

As people gradually realize the finiteness of resources and the environmental crisis caused by energy consumption, energy conservation has become one of the important contents of environmental protection and resource conservation. Thermal insulation technology has been widely used in various fields. Coatings have the problems of single function, limited effect and short validity period, making it difficult to be widely used

[0008] Traditional heat insulation materials have problems such as single function, limited effect, and short service life. At the same time, some harmful substances are added to ensure heat insulation performance during production.
