preparation example Construction

[0024] The present invention provides a kind of preparation method of the material composition that effectively reduces noise pollution, is characterized in that, comprises the following steps:

[0025] a) Mix and stir ultra-high molecular weight polyethylene powder, pore-forming agent and sound-insulating medium to obtain a mixture, the weight ratio of the ultra-high-molecular-weight polyethylene powder, pore-forming agent and sound-insulating medium is 100~300:50~ 100:100~150; the sound insulation medium is selected from one or more of modified zeolite, activated attapulgite, modified diatomite, coke powder, pumice powder and montmorillonite powder;

[0026] b) pressing, sintering and cooling the mixture obtained in step a) in a mould;

[0027] The pressing pressure is 0.4MPa-1Mpa; the sintering temperature is 200°C-250°C; the sintering time is 60-120min; the cooling temperature is 40°C-60°C.

[0028] In the present invention, firstly, the ultra-high molecular weight polyet...

Embodiment 1

[0063] (1) Take by weighing 200 g of ultra-high molecular weight polyethylene powder with a particle size of 95 μm. The ultra-high molecular weight polyethylene is the M-I type product of Beijing Dongfang Petrochemical Co., Ltd. Auxiliary No. 2 Factory, and its molecular weight is 1.5 million;

Abstract

The invention provides a preparation method of a material composition for effectively relieving noise pollution. The preparation method is characterized by comprising the following steps: a) ultrahigh molecular weight polyethylene powder, a poring agent and a sound insulation medium are mixed to obtain a mixture; the weight ratio of the ultrahigh molecular weight polyethylene powder to the poring agent and to the sound insulation medium is 100-300: 50-100: 100-150; and the sound insulation medium is one or several of modified zeolite, activated attapulgite, modified diatomite, coke powder, pumice powder and montmorillonite powder; and b) the mixture obtained in the step a) is pressed, sintered and cooled in a mold; the pressing pressure is 0.4-1 MPa; the sintering temperature is 200-250 DEG C; the sintering time is 60-120 min; and the cooling temperature is 40-60 DEG C. The prepared material composition can preferably relieve the harm of the noise pollution to people.

Description

technical field [0001] The invention relates to a preparation method of a material composition which can effectively reduce noise pollution. Background technique [0002] Construction site noise, commercial noise, domestic noise, road noise, hip-hop noise, urban rail transit noise and vibrations and other pollution have formed a noise siege, and have become the three major pollution sources alongside air pollution and water pollution. Japan even ranks noise as the first public nuisance, and it is urgent to control noise pollution. [0003] Noise can cause irreversible damage to the two parts of the ear. Sudden noise can break the eardrum and crack the connective bones, malleus, incus and pedal bones in the middle ear, resulting in hearing loss and loss. The cochlea is a part of the inner ear, and there are sensory cells in it. There are about 16,000 of these cells in each ear. They transmit sound stimulation to the nerves to the brain, destroying these cells, that is, destr...
