Problems solved by technology

Glass wool products have multiple functions such as heat preservation, heat insulation, sound absorption and noise reduction, but their shortcomings are also very obvious: 1) It is not environmentally friendly. The production of glass wool consumes a lot of energy and produces huge pollution. It has been banned in developed countries such as Europe and the United States. Glass wool products
2) Protection must be done during production and installation, otherwise it will cause physical injury to the construction personnel and increase the difficulty of construction
3) During use, the glass fiber is easy to break and fall off, causing damage to human skin, lungs and other organs
4) Wasted and eliminated glass wool is likely to cause environmental pollution
But it is soft and has no fixed shape, so it cannot be used as an engineering material on a large scale

Abstract

The invention relates to an engineering material and a preparation method thereof, in particular to an engineering material made of wool. The engineering material is composed of wool. The engineering material is characterized in that: the wool is dipped by adhesive, dried, carded and solidified. The engineering material made by the invention is a novel environment-friendly engineering material with functions of good sound absorption and heat preservation. The engineering material can be used to replace glass cotton material.

Description

technical field [0001] The invention relates to an engineering material, especially an engineering material with wool as raw material. [0002] The present invention also relates to a method for manufacturing the above-mentioned engineering material. Background technique [0003] At present, glass wool products are widely used in decoration engineering materials in our country. Glass wool products have multiple functions such as heat preservation, heat insulation, sound absorption and noise reduction, but their shortcomings are also very obvious: 1) It is not environmentally friendly. The production of glass wool consumes a lot of energy and produces huge pollution. It has been banned in developed countries such as Europe and the United States. Glass wool products. 2) Protection must be done during production and installation, otherwise it will cause physical injury to the construction personnel and increase the difficulty of construction. 3) During use, glass fibers are ...
