Abstract

The invention discloses a nylon 12 extrusion coating material for a new energy automobile, which comprises the following components: nylon 12 with 100 parts by weight of nylon 12, 50-60 parts of butadiene, 0.1-1 part of a modification additive, 5-8 parts of polytetrafluoroethylene powder, 5-25 parts of an EVA copolymer, 1-5 parts of mica powder, 2-5 parts of a wear-resistant agent, 2-3 parts of a POE elastomer and 0.2-1 part of silicone powder. The preparation method of the nylon 12 comprises the following steps: 1) preparing materials and weighing: sequentially preparing 100 parts by weight of nylon 12 and 50-60 parts by weight of butadiene; the silicone powder is selected to improve the flowability and the processability of the material, and the EVA copolymer, the polytetrafluoroethylene powder, the mica powder and the POE elastomer are selected as materials for improving the temperature resistance and the processability, so that the material has the advantage of good temperature resistance; the problems that the temperature resistance and the processability of an existing nylon 12 extrusion coating material are effectively improved, metal pieces such as copper, iron and aluminum cannot be effectively coated, and the existing nylon 12 extrusion coating material is not suitable for long-term use in a high-temperature environment are solved.

Description

technical field [0001] The invention relates to the technical field of nylon 12, in particular to a nylon 12 extrusion coating material for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source (or the use of conventional vehicle fuels, the use of new vehicle power units), and the integration of advanced technologies in vehicle power control and driving. New technology and new structure of automobiles, and nylon 12 will be used in new energy vehicles. The scientific name of nylon 12 is polydodecanolactam, also known as nylon 12. The basic raw material of its polymerization is butadiene, which can depend on petroleum Chemical industry is a semi-crystalline-crystalline thermoplastic material, but the temperature resistance and processing performance of the existing nylon 12 extrusion coating material are also effectively improved, and it cannot effectively coat metal parts such as copper, iro...
