Abstract

The invention discloses a wood-imitating profile prepared through glass fiber reinforced plastic waste regeneration and a preparation process thereof. The wood-imitating profile comprises a wrapping layer and a core material. The wrapping layer is a thin-walled polymer thermal-response shrinkage tube. The core material is prepared from, by weight, 40-130 parts of glass fiber reinforced plastic waste regeneration powder, 0.1-5 parts of ester bond in-situ processing active catalyst, 0-1.5 parts of silane coupling agent, 50-150 parts of polyolefin resin regeneration material, 0.5-20 parts of foaming master bath, 0.2-2 parts of sodium bicarbonate, 0.1-0.5 part of foaming promoter, 0.5-5 parts of dispersed lubricant A and 0.2-2.5 parts of heat stabilizer. The foaming master batch is prepared from, by weight, 25-75 parts of linear polyethylene, 20-75 parts of adhesion promoting resin, 1-15 parts of azodicarbonamide and 1-5 parts of dispersed lubricant B. The prepared multifunctional high-strength multi-layer wood-imitating profile is stable in structure and free of warping and stripping, and meanwhile recycled materials are effectively prevented from influencing the user friendliness and environmental protection property of the wood-imitating profile by the environmental protection problem of raw materials.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an imitation wood profile prepared by recycling glass fiber reinforced plastic waste and a preparation process thereof. Background technique [0002] FRP composite material is a kind of glass fiber and carbon fiber reinforced composite material with thermosetting resin as binder. With the wide use of FRP products in industrial and civil fields, the redundancy generated by the decommissioning waste of such FRP products or product production The material keeps increasing. [0003] The amount of this kind of waste in our country is calculated in hundreds of thousands of tons every year, and most of them are treated as domestic waste. According to the survey, in the next 5 to 10 years, the wind power industry will retire more than 50,000 tons of fiberglass wind turbine blades every year. This kind of thermosetting waste is difficult to be reused, and the incineration co...
