Environment-friendly inorganic fiber heat insulation felt and preparation method thereof

Abstract

The invention discloses an environment-friendly inorganic fiber heat insulation felt and a preparation method thereof. The environment-friendly inorganic fiber heat insulation felt comprises a heat insulation inner layer and a heat insulation outer layer, wherein the heat insulation outer layer is formed on the heat insulation inner layer; the heat insulation outer layer is made of an inorganic fiber cloth, and an inorganic fiber heat insulation cotton; the heat insulation inner layer and the heat insulation outer layer are adhered by an adhesive. The preparation method of the environment-friendly inorganic fiber heat insulation felt comprises the following steps of uniformly coating a sodium silicate adhesive onto the surface of the heat insulation outer layer, and covering the heat insulation inner layer at one side, coated with the adhesive, of the heat insulation outer layer; pressing and forming, cooling, and cutting, so as to obtain the environment-friendly inorganic fiber heat insulation felt. The environment-friendly inorganic fiber heat insulation felt has the advantages that the fluffy structure is formed, so that the heat insulation property is better; the thickness is small, the weight is light, the tensile strength is strong in the weft and warp directions, the fireproof property is realized, and the service life is long; the surface is smooth and flat, the easiness in contamination is avoided, the dissolvability is realized, and the pollution to environment is avoided.

Description

technical field [0001] The invention relates to the technical field of thermal insulation. More specifically, it relates to an environment-friendly inorganic fiber thermal insulation felt and a preparation method thereof. Background technique [0002] In the fields of greenhouses, greenhouses, transportation insulation, etc., traditional thermal insulation covering materials include straw thatch, composite thermal insulation blanket, acrylic cotton thermal insulation, cotton felt thermal insulation quilt, foam thermal insulation quilt, cotton quilt, etc. However, these traditional thermal insulation covering materials have the disadvantages of labor-intensive and labor-intensive rolling and unwinding; in addition, after some traditional thermal insulation covering materials are wetted by rain and snow, they not only increase the weight, but also reduce the thermal insulation performance, and cause serious pollution to the covering. The toughness is poor, the service life is...

AI Technical Summary

Problems solved by technology

However, these traditional thermal insulation covering materials have disadvantages such as labor-intensive rolling and unwinding; in addition, some traditional thermal insulation covering materials are soaked by rain and snow, which not only increases the weight, but also reduces the thermal insulation performance, and seriously pollutes the covering. Poor toughness, short service life, and pollute the environment again after being discarded
