Abstract
The invention provides a method for manufacturing an environment-friendly density board. The technical proposal of the method is that crushed cotton straws are adopted as the main material; non-formaldehyde bonding adhesive, flame-retarded unsaturated resin and active carbon are added to the crushed cotton straws; the materials are subject to extrusion forming after mixed and well stirred; and then, the surface of the manufactured density board is provided with a varnished paper melamine facing by heat pressing at high temperature. As the active carbon is added in the materials of the structure of the density board, during long-term application, the active carbon can absorb harmful substances decomposed and released by the density board. The invention has the advantages of environmental protection, flaming retarding, high strength and low cost.
Description
One, technical field: the present invention relates to a kind of manual manufacture sheet material, particularly a kind of environmental protection density plate.
Two, background technology: mostly there is formaldehyde noxious material such as exceed standard in existing density board, and causes damage for user's health.
Three, summary of the invention: the present invention is exactly at the problems referred to above, a kind of preparation method of environmental protection density plate is provided, its technical scheme is: the present invention adopts cotton straw after the pulverizing as major ingredient, cotton stalk is pulverized the back and is added no-formaldehyde adhesive, fire-retardant unsaturated-resin, active carbon, above-mentioned material mixes and to stir evenly the back extrusion forming, then on the surface that makes density board through high temperature hot pressing one deck melamine dipping lacquer paper veneer.Cotton stalk, no-formaldehyde adhesive, fire-retardant unsaturated-resin, active carbon percentage by weight are: cotton stalk 75%, no-formaldehyde adhesive 5%, fire-retardant unsaturated-resin 12%, active carbon 8%.Because of having added active carbon in this density board structural material, in long-term use, active carbon can absorb density board and decompose the harmful substance that discharges.The present invention have environmental protection, fire-retardant, intensity is high, at the bottom of the cost.
Four, the specific embodiment: earlier cotton stalk is pulverized, 75% cotton stalk is added 5% no-formaldehyde adhesive, 12% fire-retardant unsaturated-resin, 8% active carbon, the above-mentioned material mixing stirs evenly the back extrusion forming, gets final product through high temperature hot pressing one deck melamine dipping lacquer paper veneer on the surface that makes density board then.
Claims (2)
1, a kind of preparation method of environmental protection density plate, it is characterized in that: cotton stalk is pulverized the back and is added no-formaldehyde adhesive, fire-retardant unsaturated-resin, active carbon, above-mentioned material mixes and to stir evenly the back extrusion forming, then on the surface that makes density board through high temperature hot pressing one deck melamine dipping lacquer paper veneer.
2, the preparation method of a kind of environmental protection density plate according to claim 1, it is characterized in that: cotton stalk, no-formaldehyde adhesive, fire-retardant unsaturated-resin, active carbon percentage by weight are: cotton stalk 75%, no-formaldehyde adhesive 5%, fire-retardant unsaturated-resin 12%, active carbon 8%.
