Abstract

The invention relates to the technical field of resin materials, in particular to a bamboo carbon fiber phenolic resin composite material. The bamboo carbon fiber phenolic resin composite material isprepared from the following raw materials in parts by weight: 75 to 87 parts of phenolic resin, 40 to 60 parts of polyamide curing agent T31, 15 to 25 parts of modified bamboo carbon fibers, 2 to 10 parts of hydroxymethyl cellulose, 1 to 7 parts of N-methyl acetamide, 1.5 to 3 parts of AC foaming agent, 3 to 9 parts of PVC foaming regulator, 1 to 2.5 parts of brominated polyethylene, 0.3 to 1.6 parts of stearic acid, 0.4 to 3.5 parts of talcum powder, and 1.2 to 3 parts of potassium hexatitanate whisker. The bamboo carbon fiber phenolic resin composite material is excellent in mechanical performance.

Description

technical field [0001] The invention relates to the technical field of resin materials, in particular to a bamboo carbon fiber phenolic resin composite material. Background technique [0002] Bamboo carbon fiber is made of moso bamboo as raw material, and adopts a new calcination process and new technology of pure oxygen high temperature and nitrogen barrier delay, which makes the micropores inherent in bamboo charcoal more refined and honeycombed, and then combined with the trend of honeycomb microporous structure It is made by melt spinning polyester modified chips. At present, bamboo carbon fiber is often used to enhance the performance of resin materials, but due to the poor compatibility of bamboo carbon fiber and resin, the performance of the material is not good, and it is difficult to improve the benefits of enterprises. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a bamboo...
