preparation example Construction

[0036] The preparation method of the EAODM elastomer of the present invention can be prepared by those methods known in the art.

[0037] thermoplastic polyolefin

[0038] As the thermoplastic polyolefin, resins that can be selected in the present invention include polyethylene-based resins and polypropylene-based resins.

[0039] Polyethylene-based resins include: high-pressure low-density polyethylene, high-density polyethylene, ethylene-α-olefin copolymer, ethylene-unsaturated ester copolymer and other polyethylene-based resins.

[0040] As the high-pressure low-density polyethylene, for example, high-pressure low-density polyethylene having a density of 910 to 930 kg / m3 is exemplified. Moreover, as a high-density polyethylene, the high-density polyethylene whose density is 941-970 kg / m3 is mentioned, for example. The density is a value measured according to the method specified in JIS K6760-1981.

[0041] The ethylene-α-olefin copolymer is an ethylene-α-olefin copolymer...

Embodiment approach 1

[0085] Embodiment 1, TPV for high wear-resistant automobile dust cover, the TPV is prepared from a vulcanized mixture through a dynamic vulcanization process, and the vulcanized mixture at least includes 100 parts by weight of EOADM elastomer, 0.1-30 parts by weight of benzene ring-containing Polymer, 50-200 parts by weight of thermoplastic polyolefin, 0.1-10 parts by weight of carboxyl or acid anhydride graft polymer and 0.01-20 parts by weight of crosslinking agent.

Embodiment approach 2

[0086] Embodiment 2 is the same as Embodiment 1, except that the benzene ring-containing polymer is a benzene ring-containing elastomer and / or a benzene ring-containing thermoplastic polymer.

Abstract

The invention relates to TPV for a high-abrasion-resistance automobile dustproof cover. The TPV is prepared through a vulcanized mixture through the dynamic vulcanization technology. The vulcanized mixture at least comprises, by weight, 100 parts of EOADM elastomer, 0.1-30 parts of benzene-ring-containing polymer, 50-200 parts of thermoplastic polyolefin, 0.1-10 parts of carboxyl or anhydride graft polymer and 0.01-20 parts of a cross-linking agent. The TPV has good abrasion resistance in the use environment of the automobile dustproof cover.

Description

technical field [0001] The invention relates to a TPV for a high wear-resistant automobile dust cover, and also relates to a preparation method of the TPV for a high wear-resistant automobile dust cover. In particular, International Patent Classification number C08L53 / 00 is involved. Background technique [0002] The car dust cover protects the drive shaft and other devices of the car to prevent foreign matter such as grease and dust from harming the corresponding devices. The dust cover will inevitably rub against each other during use, and the car dust cover is easily damaged in the grease environment and high temperature environment. Neoprene, traditionally used to make car dust covers, contains harmful substances and is gradually being phased out with the development of technology. [0003] TPVs can be formed between many plastics and rubbers, but only a few blends are of practical value after dynamic vulcanization. In the book "Thermoplastic Elastomers" of the Chemic...
