Method for preparing sound insulation cotton from polyvinyl chloride

Abstract

The invention discloses a method for preparing sound insulation cotton from polyvinyl chloride. The method comprises the following steps: 1) preparing a to-be-processed raw material block from corresponding parts by mass of raw materials, and adding the raw material into a drying box; 2) coating and bonding solid polyvinyl chloride with the raw material block, and placing the obtained material inthe drying box; 3) putting the treated raw material obtained in step 2) into a reaction kettle; 4) stirring and cooling a product obtained in step 3), and drying the stirred and cooled product; 5) performing finishing by a cotton feeding machine and a cotton carding machine to form a cotton felt; 6) putting the cotton felt in a blanking machine, and blanking the cotton felt; and 7) sewing the blanked cotton felt, and gluing the surface of the sewed felt to obtain the sound insulation cotton. The polyvinyl chloride component is added, so the heat resistance of the sound insulation cotton prepared by the method is remarkably improved, the sound insulation effect of the sound insulation cotton is not reduced, or even the sound insulation effect is improved.

Description

technical field [0001] The invention relates to a method for preparing sound-insulating cotton by using polyvinyl chloride as a raw material, and belongs to the technical field of sound-insulating cotton production. Background technique [0002] At present, the use of sound insulation cotton involves many places, including large noise machinery and equipment in processing plants, air conditioners and refrigerators used at home. On the one hand, the sound insulation cotton needs to reduce its own heat, and on the other hand, it needs to improve the sound insulation effect through the internal tightness. At present, the sound insulation cotton can improve the heat resistance through the combination of sound insulation cotton and polypropylene material, but due to the pure use of polypropylene material Combining with sound insulation cotton cannot completely eliminate the problem of overheating of sound insulation cotton when the air conditioner is working.
