Lightweight environment-friendly smokeless thermal insulation material for household appliances

Abstract

The invention discloses a lightweight environment-friendly smokeless thermal insulation material for household appliances, and relates to the technical field of thermal insulation materials. The lightweight environment-friendly smokeless thermal insulation material comprises a base material layer and a thermal insulation layer, wherein an anti-corrosion cloth layer is fixed on the upper side of the base material layer, a flame retardant layer is fixed on the upper side of the anti-corrosion cloth layer, reinforcing nets are fixed above the flame retardant layer, sound insulation layers are arranged among the reinforcing nets, and the thermal insulation layer is fixed above the reinforcing nets. The light environment-friendly smokeless thermal insulation material for household appliances is formed by pressing the carbon fiber base layer, a composite polyester fiber layer, a composite flame-retardant fiber layer, a glass fiber gridding cloth foam cotton layer and a glass cotton layer; the carbon fiber base layer is light in weight and can resist high temperature; the composite polyester fiber layer is good in elasticity and has a certain corrosion-resistant effect; thermoplastic resin is added in a preparation process, so corrosion-resistant performance is further enhanced; the composite flame-retardant fiber layer is prepared in a blended mode and has flame-retardant and heat-insulating performance; and glass fiber gridding cloth has the advantages of being high in strength and light in weight.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a lightweight and environment-friendly thermal insulation material for smokeless home appliances. 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. Smoke-free home appliances refer to green home appliances such as induction cookers, ovens, and microwave ovens that "cook without open flames and smoke". When in use, insulation materials are usually required to prevent the transfer of heat load. [0003] Existing thermal insulation materials mostly consider building thermal insulation, are not suitable for smoke-free home appliances, and do not perform well in light-weight envir...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a light-weight and environment-friendly thermal insulation material for smoke-free home appliances, which solves the problem that the existing thermal insulation materials proposed in the above-mentioned background technology mostly consider building thermal insulation and are not suitable for smoke-free home appliances. , and it does not perform well in terms of light weight, environmental protection, flame retardant and heat insulation, and the preparation process is relatively complicated.
