Glass fiber heat insulation felt and manufacturing method thereof

Abstract

The invention provides a glass fiber heat insulation felt. The fiber felt is prepared by overlapping at least 10 layers of thin fiber felts, wherein each thin fiber felt is 0.1-1mm in thickness, and the grids of the thin fiber felts are 1-200 microns. The glass fiber heat insulation felt completely meets the requirement of non-combustible A1 level and is the first heat preserving, heat insulatingand fireproofing material; and meanwhile, suck material has the characteristics of being soft, foldable, capable of being wrapped, and easy to construct.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a glass fiber thermal insulation felt. Background technique [0002] The thermal insulation and energy-saving materials used in domestic and foreign industries and buildings mainly include: ①rock mineral wool, glass wool, high-performance fibers and their products, ②airgel and their products, ③organic foam insulation materials and their products, ④hard Thermal insulation materials and their products, ⑤Asbestos thermal insulation materials and their products. [0003] All of the above insulation materials have defects: [0004] ① There are many problems in the application process of rock mineral wool: such as insufficient strength, the material sags, breaks, and heat preservation failure due to its own gravity during use; the irritation to the skin is too large, and workers are unwilling to construct; the toughness of the material and Insufficien...

AI Technical Summary

Problems solved by technology

[0004] ①There are many problems in the application process of rock mineral wool: such as insufficient strength, the material sags, breaks, and heat preservation failure due to its own gravity during use; it is too irritating to the skin, and workers are unwilling to construct; the toughness of the material and Insufficient rebound, fiber breakage after compression or kneading, dust flying, can not guarantee effective insulation thickness, can not achieve the desired effect; temperature resistance is not enough, when used above 200 ℃, rock mineral wool and ordinary glass wool are prone to aging and hair loss brittle, badly damaged

[0007] ④ Rigid thermal insulation products are used in specific occasions (such as foam concrete blocks, etc.), because they are fragile and cannot be covered on the surface, the market scale is small and the market development is slow
