Abstract

The invention discloses an environmentally friendly automobile noise and heat insulation material and a processing method thereof. The environmentally friendly automobile noise and heat insulation material is prepared from, by weight, 50-70 parts of packing, 10-22 parts of DF740 elastomer, 2-7 parts of 100 # white oil and 0.1-0.5 part of an additive, wherein the packing is any proportion of mixture of one or two of barium sulfate and calcium carbonate, and the additive is TiO2, ZnO, CdS or WO3. The additive having a photocatalytic effect is added, the contents of aldehyde and benzene series in the environmentally friendly automobile noise and heat insulation material are effectively reduced, and the problem of high VOC content of automotive trims is solved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an environment-friendly automobile sound and heat insulation material and a processing method thereof. Background technique [0002] At present, the sound-insulating and heat-insulating hard-layer sheets of automobiles are made by mixing high-polymer plastic particles and fillers at high temperatures. Some small molecular substances such as aldehydes and benzenes are produced. The small molecular substances have a low melting point, exist in the form of gas at room temperature, and are volatile at room temperature. Therefore, when this sheet is used in automobiles, although the sound insulation and heat insulation effect is remarkable, it is easy to emit various aldehydes and benzene small molecule gases, which will cause certain damage to the body of people who drive for a long time. Contents of the invention [0003] The invention provides an environment-friendly automobile sound-i...
