Embodiment 1

[0035] A preparation method of an anti-noise fiber material pad, comprising the following steps and process conditions:

[0036](1) Preparation of ultra-thin fiber sound-absorbing material: Dissociate the main fiber material with a pressure disc mill, and by weight percentage, the main fiber material is made of 70% pine fiber, 23% alkali-free glass fiber (specification: length 15mm × The fineness is 12um, produced by Shijiazhuang Hongweijie Trading Co., Ltd.) and 7% mineral wool fiber (specification: particle diameter ≤ 30mm, produced by Langfang Qiyuan Refractory and Energy-saving Materials Co., Ltd.). In the main fiber material, add crystalline cellulose (model HW325, produced by Henan Province So Chemical Co., Ltd.) accounting for 0.8% of the dry main fiber material weight, and add 0.3% nanometer calcium carbonate (model MCA3000, Shanghai Zhizhen Chemical Co., Ltd.) and 0.7% magnesium hydroxide (model: TIGER-B15, produced by Dongguan Daoer Chemical Co., Ltd.), blending modi...

Embodiment 2

[0043] A preparation method of an anti-noise fiber material pad, comprising the following steps and process conditions:

[0044] (1) Preparation of ultra-thin fiber sound-absorbing material: Dissociate the main fiber material with a pressure disc mill, and the main fiber material is composed of 64% poplar fiber and 23% alkali-free glass fiber (specification: length 12mm) × Fineness 12um, produced by Shijiazhuang Hongweijie Trading Co., Ltd.) and 13% mineral wool fiber (specification: particle diameter ≤ 30mm, produced by Langfang Qiyuan Refractory and Energy-saving Materials Co., Ltd.). In the main fiber material, add crystalline cellulose (model HW325, produced by Henan Province So Chemical Co., Ltd.) accounting for 0.9% of the dry main fiber material weight, and add 0.8% nanometer calcium carbonate (model MCA3000, Shanghai Zhizhen Chemical Co., Ltd.) and 1.1% magnesium hydroxide (model: TIGER-B15, produced by Dongguan Daoer Chemical Co., Ltd.), blending modification; and the...

Embodiment 3

[0049] A method for preparing a novel anti-noise fiber material pad, comprising the following steps and process conditions:

[0050] (1) Preparation of ultra-thin fiber sound-absorbing material: Dissociate the main fiber material with a pressure disc mill, and by weight percentage, the main fiber material consists of 63% non-wood straw fiber, 21% alkali-free glass fiber (specification: length 12mm×12um fineness, produced by Shijiazhuang Hongweijie Trading Co., Ltd.) and 16% mineral wool fiber (specification: particle diameter ≤ 30mm, produced by Langfang Qiyuan Refractory and Energy-saving Materials Co., Ltd.). In the main fiber material, add crystalline cellulose (model HW325, produced by So Chemical Co., Ltd. in Henan Province) that accounts for 0.2% of the dry main fiber material weight, and add 0.4% nanometer calcium carbonate (model MCA3000, Shanghai Zhizhen Chemical Co., Ltd.) and 0.8% magnesium hydroxide (model: TIGER-B15, produced by Dongguan Daoer Chemical Co., Ltd.),...

Abstract

The invention discloses an anti-noise fiber material cushion and a preparation method thereof. The material cushion is formed by overlapping at least two layers comprising an ultrathin fiber sound absorption material layer and an ultra-micro perforation sound absorption plate material layer, and the thickness of the material cushion is between 2 and 8 mm; the ultra-micro perforation sound absorption plate material layer is an ultrathin PVC paper board with the porosity of 0.2 to 3 percent; the ultrathin fiber sound absorption material layer is formed by overlapping 1 to 10 layers of fiber sound absorption materials with thickness of 0.2 to 2 millimeters; and the ultrathin fiber sound absorption material consists of a main fiber material and an auxiliary material. The anti-noise fiber material cushion has good noise reduction effect within a full audio frequency range, and particularly has quite obvious sound absorption performance of the noise under a high frequency; the noise is reduced by 2 to 8dB; and the anti-noise fiber material cushion is widely applied to the industrial fields of air conditioners, refrigerators, washing machines, automobiles, spaceflights and the like, and has quite important potential application value on noise reduction, energy conservation, consumption reduction and improvement of market competitiveness of products with higher noise requirements.

Description

technical field [0001] The invention relates to an anti-noise fiber material, in particular to a fiber material pad which is green and environment-friendly and has a full-frequency noise reduction function and a preparation method thereof. The material pad can be used as a noise reduction material in the field of the modern household appliance industry. Background technique [0002] With the rapid development of the world economy and the enhancement of people's environmental awareness, people's requirements for living standards have also been continuously improved. Home appliances such as air conditioners, refrigerators, washing machines, etc. Convenience and work efficiency. In modern society, people put forward higher and higher requirements for the living environment, not only requiring the living environment to be warm in winter and cool in summer, but also requiring as little noise pollution as possible. However, these products will cause a certain amount of environmen...
