Abstract

The invention aims to provide a PVC (polyvinyl chloride) rubber formula applied to sound-insulation cotton. According to the PVC formula applied to the sound-insulation cotton, a PVC raw material and calcium powder are taken as the main raw materials, a foaming agent and a plasticizer are adjunctively added, butadiene-acrylonitrile rubber is added to enable that the wear and heat resistances are good and the binding powder is strong, silicone rubber is added to enable that the high temperature resistance and the air permeability are good, a fire retardant is added to resist flame, and an infrared reflection pigment is added to emit and radiate infrared rays in sunlight; therefore, high temperature generated by irradiation is avoided, performances are excellent, and the PVC rubber formula is suitable for the sound-insulation cotton.

Description

technical field [0001] The invention relates to the field of PVC rubber, in particular to a PVC rubber formulation for sound-insulating cotton. Background technique [0002] Our company mainly produces PVC rubber for sound insulation cotton. The sound insulation cotton is coated with glue through PVC rubber and then glued with a layer of cotton felt, and then cut into the required shape. PVC rubber is the main component of sound insulation cotton, its performance is particularly important, but the performance of the current PVC rubber is not so good, so it is very necessary to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a PVC rubber formula for sound-insulating cotton, PVC raw material and calcium powder are main raw materials, auxiliary foaming agent and plasticizer are added, and acrylonitrile-butadiene rubber is added to make it wear-resistant and heat-resistant. Strong adhesion, addi...
