Method for improving shore degree of sound insulation cotton

Abstract

The invention relates to a method for improving the shore degree of sound insulation cotton. The method comprises the following specific steps: weaving to obtain a light metal net layer and a hollow metal net layer; embedding elastic reinforcing ribs in a foam plastic layer; penetrating an elastic layer, drilling holes on the elastic layer, and filling light metal fiber; embedding mixed fibers in a soft resin plate layer; carrying out laminating treatment on the mixed fiber layer; and finally, stacking the layers in sequence, hot-pressing and pressing to obtain the sound insulation cotton, and sealing the edge by using an anti-aging film. According to the designed method for improving the shore hardness of the sound insulation cotton, double-layer woven metal nets are additionally arranged in the sound insulation cotton, the resin plate and the elastic layer are arranged between the metal nets, and the sound insulation effect and shore hardness of the sound insulation cotton are improved through the metal nets, the resin plates and the elastic layers; and the shore hardness and the sound insulation effect are further enhanced through the mixed fibers on the surface layer, so that the shore degree and the sound insulation effect of the sound insulation cotton are integrally improved, and the sound insulation cotton has good market potential value and application prospect and has practicability and creativity.

Description

Technical field[0001]The present invention belongs to the field of sound insulation materials, and in particular, the present invention relates to a method of increasing sound-proof cotton.Background technique[0002]Hardness is a physical metric manner that is the degree of substance pressure deformation or the resistance of puncture. Hardness can be divided into relative hardness and absolute hardness. The absolute hardness is generally used in the scientific community, and it is rarely used in production practices. We usually use the hardness system as relative hardness, often with the following marking methods: Shore (also called Shao, Shao, English Shore), Luo, Bell. Shore is generally used in rubber materials; Shaw's hardness refers to the reading of the value measured by Shore hardness meter, its unit is "degree", its description method is divided into two, representing different hardness Range, 90 degrees and less test, and draw data, 90 degrees and more D hardness meter testi...

AI Technical Summary

Problems solved by technology

Due to the advantages of inorganic flame retardants: low toxicity, good thermal stability; no precipitation, durable flame retardant effect; no corrosive gas; low price; The application of organic flame retardants is gradually replacing organic flame retardants, so the research on synthetic inorganic flame retardants is of great significance; but because organic flame retardants are still used in large quantities, it is advisable to use inorganic flame retardants in combination with organic flame retardants. way of transition

[0005] At present, the society's demand for sound insulation materials is growing rapidly, and traditional sound-absorbing materials can no longer meet people's higher requirements for environmental protection, decoration, flame retardancy, aging resistance and hardness.
