Abstract

The invention relates to the field of polymer composite materials, in particular to a metal and polyolefin composite material, a preparation method thereof and a container. The composite material of the metal and the polyolefin comprises a metal material and a polyolefin material, the polyolefin material is obtained by performing a cross-linking reaction on a polyolefin composition, the polyolefincomposition comprises polyolefin, a compatilizer, a peroxide cross-linking agent and a silane coupling agent, and relative to 100 parts by weight of polyolefin, the content of the compatilizer is 0.1-20 parts by weight, the content of the peroxide cross-linking agent is 0.01-6 parts by weight, and the content of the silane coupling agent is 0.1-5 parts by weight. The metal and polyolefin composite material provided by the invention is not easy to crack, good in high temperature resistance and longer in service life.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to a composite material of metal and polyolefin, a preparation method of the material, and a container made of the material. Background technique [0002] Crosslinkable polyolefin has excellent high temperature resistance, chemical corrosion resistance, good impact strength, etc., and has important application value in chemical storage and transportation, oil and gas transportation, and chemical anticorrosion. However, as a low-polarity mixture, crosslinkable polyolefin has poor adhesion to polar substrates (such as metals), so the metal part and polyolefin part in the prepared polyolefin and metal composite member are easy to peel off, greatly Reduced service life of polyolefin and metal composite components. [0003] At present, there are few dedicated studies on the metal bonding properties of polyolefins. Therefore, finding a composite material of metal and polyolefi...
