AI Technical Summary

Problems solved by technology

Since the rubber inlet pipe and the diversion pipe are insulating materials and do not have electrical conductivity, during the entire pouring process, the charge generated by the resin through the friction of the pipeline accumulates on the inner wall of the pipeline, generating static electricity, which poses a certain safety hazard

Abstract

The invention provides conductive adhesive resin of a vacuum infusion tube for wind power and a preparation method of the conductive adhesive resin. The conductive adhesive resin comprises the following components in parts by mass: 80-120 parts of adhesive resin, 5-10 parts of conductive filler and 5-10 parts of coupling agent, wherein the adhesive resin is prepared from the following components in parts by mass: 30 to 40 parts of high-density polyethylene, 20 to 30 parts of linear low-density polyethylene, 20 to 30 parts of tackifying resin, 5 to 10 parts of POE (Polyolefin Elastomer), 1 to 5 parts of viscosity modifier and 0.1 to 0.5 part of antioxidant. The conductive bonding resin has good high and low temperature resistance and durability, has a good bonding effect on a vacuum infusion tube, and meanwhile, the graphene oxide-silver composite particles are selected as the conductive filler, so that the conductive performance is better than that when the conductive filler is all silver powder or graphene oxide, and the conductive performance is better than that when the conductive filler is silver powder or graphene oxide. The conductive adhesive resin has good flame-retardant and antistatic performance, and the whole vacuum infusion tube can have antistatic performance.

Description

technical field [0001] The invention relates to the field of adhesive resins, in particular to a conductive adhesive resin for a vacuum infusion tube for wind power and a preparation method thereof. Background technique [0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. As one of the new energy sources with the most mature technology and the most commercial development prospects, it is being used on a large scale. Wind power blades are mostly made by vacuum infusion process. The vacuum infusion process is to lay reinforcement material, release cloth, isolation film and diversion net on the mold in sequence, and then arrange a diversion pipe on the diversion net, and seal the reinforcement material and vacuum auxiliary medium in the vacuum bag film with sealing tape. Vacuum, connect the guide tube and the rubber inlet tube, and the resin enters all corners of the blade layup under the action of atmospheric pressure to compl...
