Composite adhesive rubber-plastic heat-insulation material

Abstract

The invention discloses a composite adhesive rubber-plastic heat-insulation material including a body. A moisture barrier layer, a fireproof layer and an antibacterial layer are formed successively onthe surface of the body from interior to exterior, the fireproof layer being a glass fiber cloth and the moisture barrier layer being kraft paper. The body includes, by weight, 50-60 parts of nitrilebutadiene rubber, 20-25 parts of EVA, 5-8 parts of Al(OH)3, 10-12 parts of MgO, 5-8 parts of nano SiO2, 9-15 parts of PVC, 10-15 parts of basalt, 10-15 parts of zirconia, 2-5 parts of talcum powder,13-19 parts of chlorinated paraffin, 11-17 parts of carbon black, 17-21 parts of zinc dimethyldithiocarbamate, 25-35 parts of expanded perlite, 11-15 parts of a low temperature resistant plasticizer,5-10 parts of a halogen-free flame retardant, and 2-5 parts of filler. The heat-insulation material is prepared from low-cost raw materials and has advantages of high heat insulation, fire proofing and moisture barrier functions.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a composite viscose rubber-plastic thermal insulation material. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.12. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. Every ton of mineral wool insulation products used in buildings can save one ton of oil a year. The traditional thermal insulation materials are mainly to increase the gas phase void ratio and reduce the thermal conductivity and conductivity coefficient. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insula...

Problems solved by technology

But this is only owned by developed countries abroad, so the purchase cost is too high

[0003] With the continuous advancement of science and technology in my country, the level of thermal insulation technology in my country has also been greatly improved in recent years, and the production capacity of thermal insulation materials is also expanding. There is a large gap between the application technology and foreign countries, and there is still a considerable gap in the overall thermal insulation and energy saving benefits compared with developed countries, so it needs to be improved
