Method for producing ecological plate floor substrate

Abstract

The invention discloses a method for producing an ecological plate floor substrate. The mixture ratio of the wood sort of coniferous wood to broad-leaved wood is 3:7; wetting treatment is carried out on the upper and lower surfaces of a slab during the paving process; the water spraying quantity of the upper and lower surfaces is 34 / 29g / m<2>; the inlet of a pressing machine is closed quickly so as to achieve the maximum pressure; the pressure at the high-pressure area is 350N / cm<2>; the hot-pressing temperature of a first area is 230 DEG C; the high-pressure is slowed depressurized; the sanding proportions for crude sands and fine sands are 65% and 35% respectively; the surface of a fiber board needs to be smooth and the fiber is fine; and the surface of the fiber board are free of gum spot, water stain, oil stain, dust spot and bark impurities. The method has simple production process and low requirements on equipment, production process condition and raw material, and most of artificial board enterprises can meet the production conditions of the product. The adopted adhesive is the same with normal laminate flooring adhesive, no special adhesive is needed and the product can meet the requirements of the standard.

Description

technical field [0001] The invention relates to a production method of a medium-high density fiberboard, in particular to a production method of an ecological board floor base material. Background technique [0002] In recent years, my country's wood-based panel industry has developed rapidly, especially the development of medium and high-density fiberboard is more obvious. In the past 2007, my country's medium and high-density fiberboard continued its development trend for several years, and its production capacity has increased significantly. It is estimated that by the end of 2008, the designed production capacity of my country's medium-high-density fiberboard will reach 32.93 million m3 / a. With the increase of density board production and the continuous expansion of uses, its downstream deep processing technology and technology are also developing and changing, presenting a variety of new products to meet the concept of end-customer use and meet the needs of different gr...
