Problems solved by technology

TPV material has excellent impact strength under low temperature conditions. As an airbag cover material, it performs well in low temperature blasting. However, because the matrix is ​​polyolefin, the heat resistance is insufficient, so TPV materials have insufficient rigidity and tear strength under high temperature conditions. Poor weakness, when blasting at high temperature, it is easy to cause the airbag cover to deform and fly out due to the decrease in rigidity, or the tear strength is insufficient to cause excessive tearing

preparation example Construction

[0047] The preparation method of the EAODM elastomer of the present invention can be prepared by those methods known in the art.

[0048] thermoplastic polyolefin

[0049] Any suitable thermoplastic material can be used as the thermoplastic phase of the TPV of the present invention. A thermoplastic material is generally a material that can be molded or shaped and reprocessed at least at the softening or melting temperature of the material. Polyolefins are preferred thermoplastic materials. Polyolefins are a fundamental structural part of polymer science and engineering, as thermoplastics are based on the low cost and high throughput of petrochemical production.

[0050] Thermoplastic polyolefins include, but are not limited to, homopolymers and copolymers of the following monomers: alpha-olefins such as 1-butene, 1-pentene, 1-hexene, 2-methyl-1-propene, 3-methyl - 1-pentene, 4-methyl-1-pentene and 5-methyl-1-hexene, and ethylene, butene and propylene, but preferably homop...

Abstract

TPV (Thermoplastic Vulcanizate) for an automobile safety airbag cover material. The TPV is prepared from a vulcanization mixture by a dynamic vulcanization process; and the vulcanization mixture at least contains the ingredients in parts by weight: 100 parts of EAODM elastomer, 50-200 parts of thermoplastic polyolefin, 5-15 parts of anthranilamide compound modified polyolefin, 0.5-5 parts of phenyl acetylenic ketone compound partially-modified EAODM elastomer and 0.5-10 parts of cross-linking agent. The invention relates to the field of thermoplastic vulcanizate (TPV) and particularly relates to the TPV for the automobile safety airbag cover material and the preparation method for the TPV.

Description

technical field [0001] The invention relates to the field of thermoplastic vulcanizate (TPV), in particular to TPV for automobile airbag cover material and a preparation method thereof. Background technique [0002] Automobile airbag cover is a decorative and functional automotive interior part. In the event of a traffic accident, the airbag is deployed in an emergency and penetrates the airbag cover. Therefore, the airbag cover not only needs to ensure sufficient toughness at extremely low temperatures (-40°C), so that debris is not allowed to fly out and hurt people when the airbag penetrates and tears the cover; ) to ensure a certain degree of rigidity, and it is not allowed to deform due to insufficient high-temperature rigidity or cause excessive tearing due to too low high-temperature tear strength, causing major accidents. [0003] At present, thermoplastic elastomer (TPV) is mainly used as the cover material of automobile airbags, which are used for the cover plates...
