Abstract

The invention relates to a composite regenerated environment-friendly plate and a preparation method. The composite regenerated eco-friendly plate consists of 20 percent to 50 percent of plastic and 50 percent to 80 percent of plant fiber in weight percentage; the plastic is a mixture of one or more thermoplactic plastic materials. The preparation method includes the steps that: the plastic and crushed plant fiber are mixed with each other and dried and then are subject to a first high-temperature stirring melting at the temperature ranging from 200 to 350 DEG C for 1 to 2 minutes for extrusion; the extruded mixtures go through second high-temperature stirring melting at the temperature ranging from 150 to 220 DEG C for 1 to 2 minutes and finally are subject to high-temperature oil-pressure molding at the temperature ranging from 80 to 130 DEG C. Being manufactured at the high temperature, the plates of the invention are not deformed at the high temperature ranging from 70 to 100 DEG C, do not swell if immersed in the water for 3 months, are the typical high-temperature resistant plates, have low cost, can be recycled in an economical and environmentally protective way, simultaneously solves the problems of insufficient wood resources and white pollution, can be extensively applied to the furniture manufacturing industry and construction industry, etc.

Description

technical field [0001] The invention belongs to the field of environmentally friendly recycled materials, and relates to an environmentally friendly composite recycled environmentally friendly board that has high temperature resistance and can be recycled and utilized and a preparation method thereof. Background technique [0002] At present, the high-temperature-resistant plates on the market include plastic high-temperature plates, medium plates, and wooden decks. Among them, the plastic high-temperature board is made of plastic extracted from petroleum. In today's increasingly scarce crude oil resources, the cost will gradually increase; the middle board cannot be fireproof, waterproof, mothproof, and cannot be nailed. Secondary screws will slip and loosen, and cannot be recycled and recycled. In addition to the problems of poor fireproof, waterproof, moth-proof performance and difficulty in recycling, wooden decks are not environmentally friendly. Environmental protectio...
