Embodiment 1

[0009] Embodiment 1: A kind of high-strength invisible mesh reinforcement wood residue board core forming material, its characteristic weight parts are: add 20-25 parts of wood residue powder, add 10-20 parts of glue, add 0.05 parts of wood residue to 100 parts of crushed wood residue blocks -0.15 part of aramid fiber. The material of the broken wood slag block is a mixture of one or more of tree branches, board edges, leftover materials, and waste materials of building templates. The length, width and thickness of the broken wood slag block are controlled within the scope of 3-5cm. The water content of the broken wood residue is below 8%.

Embodiment 2

[0010] Example 2: On the basis of Example 1, 20 parts of wood residue powder, 10 parts of glue, and 0.05 part of aramid fiber were added to 100 parts of crushed wood residue blocks.

Embodiment 3

[0011] Example 3: On the basis of Example 1, 25 parts of wood residue powder, 20 parts of glue, and 0.15 parts of aramid fiber were added to 100 parts of crushed wood residue blocks.

Abstract

The invention relates to a high-strength invisible mesh reinforcement wood residue plate and a manufacturing method thereof. The high-strength invisible mesh reinforcement wood residue plate is fine in toughness, high in bearing strength, large in pressure and not easy to break in water. The manufacturing method includes the steps: (1) adding 20-25 parts of wood residue powder into 100 parts of wood refuse blocks, uniformly mixing the wood residue powder and the wood refuse blocks, and then drying the mixture at high temperature; (2) adding 0.05-0.15 part of aramid fibers into mixed materials obtained in the first step and uniformly mixing the aramid fibers and the mixed materials; (3) adding 10-20 parts of glue into the mixed materials obtained in the second step and uniformly mixing the glue and the mixed materials; (4) opening a press, firstly placing a single-surface glue leather on the lower portion, adding the mixed materials obtained in the third step, and then covering the upper portion of the mixed materials with a poplar bark; (5) starting the press to perform heat pressing for the mixed materials in the fourth step at the high temperature to obtain the high-strength invisible mesh reinforcement wood residue plate. The water content of the mixed materials is lower than 8%, the temperature of the press is controlled to range from 180 DEG C to 190 DEG C, and the pressure of the press is controlled to range from 800 tons to 1000 tons. The high-strength invisible mesh reinforcement wood residue plate has the advantages that the plate is fine in toughness, large in bearing pressure and high in strength, cannot be broken, and cannot expand in damping.

Description

technical field [0001] The invention relates to a high-strength invisible mesh-reinforced wood residue board with good toughness, high load-bearing strength and high pressure, and is not fragile when exposed to water and a manufacturing method thereof, belonging to the field of wood residue board manufacturing. Background technique [0002] CN101164746A, the name "environmentally friendly recycled wood slag density board", it is made of the following raw materials in weight ratio: 20-35 parts of main raw materials; 5-15 parts of original density board sanding powder; 3-10 parts of urine aldehyde glue, The main raw materials are scraps from plywood production; sawdust; shavings; bark and cotton stalks or a combination of two or more. Its shortcomings: first, poor toughness, easy to break; second, low pressure; third, after soaking in water for several hours, wood residue density board will decompose. Contents of the invention [0003] Design purpose: To avoid the deficienc...
