Problems solved by technology

[0004] The technical problem mainly solved by the present invention: Aiming at the fact that the surface of the ecological board produced by the three-time hot pressing process is easy to bulge, which makes the board surface uneven and increases the defective rate of the product, a method for preparing the ecological board from moso bamboo material is provided. The present invention Utilize the characteristics of moso bamboo material, that is, moso bamboo has many pores and has air permeability to make ecological boards. The ecological boards prepared by the present invention are not easy to bubble, resistant to pollution, and have no carbonization phenomenon. They can be produced in large quantities and improve production efficiency.

example 1

[0016] First select 18m bamboo, cut it 5cm away from its roots, cut off the branches on the main stem of the bamboo pole, collect the bamboo leaves on the branches, and send the trimmed main stem to the chipper to cut into shavings with a length of 30mm , And put the shavings and bamboo leaves washed with water in the sun for 3 days, then send them to the drying kiln through a pipeline, and dry them to a moisture content of 8% for later use; then take out the dried bamboo leaves and crush them with airflow The machine is pulverized into bamboo leaf powder with a particle size of 0.18mm, and then stirred and mixed for 15 minutes according to the mass ratio of bamboo leaf powder and polyvinyl chloride resin at 1:1. After it is evenly mixed, it is placed in an internal mixer for mixing. 15min, set the banburying temperature to 90℃ and the speed of 30r / min. After the banburying is completed, take it out while hot and place it on a plate vulcanizer, press it under 15MPa for 10min, an...

Abstract

The invention relates to a method for preparing an ecological board from a moso bamboo material, and belongs to the technical field of building material production. The present invention firstly collects the bamboo leaves and trunks on moso bamboo, beats the trunks into shavings, and then exposes them to the sun and dries them for later use. The dried bamboo leaves are crushed into bamboo leaf powder, stirred and mixed evenly with polyvinyl chloride resin, and Put it in an internal mixer and put it on a flat vulcanizer for hot pressing, take it out and cold press it to get the bamboo leaf resin layer, then crush the particle board into bamboo chips, mix with polyethylene resin, limestone powder and other substances, impregnate, Filtrate, wash with ethanol, dry, banbury, plasticize, cold press to obtain the middle layer of micro-foamed bamboo chips, and finally make the bamboo leaf resin layer into the upper and lower layers, and the middle layer is the middle layer of micro-foamed bamboo chips, and carry out hot pressing and cold press. Finally, the beneficial effects of the present invention are: no bubbling, pollution resistance, no carbonization phenomenon, mass production is possible, production efficiency is improved; production steps are simple, and cost is saved.

Description

Technical field [0001] The invention relates to a method for preparing ecological boards from moso bamboo materials, and belongs to the technical field of building material production. Background technique [0002] Eco-board is divided into two concepts: narrow and broad. In a broad sense, eco-board is equivalent to melamine veneer. Its full name is melamine-impregnated adhesive film paper veneer wood-based panel, which is to put paper with different colors or textures into eco-board resin Soaked in the adhesive and then dried to a certain degree of solidification, pave it on the surface of particleboard, moisture-proof board, medium density fiberboard or other hard fiberboard, and heat-press decorative board. Compared with traditional stickers, it has the advantages of high temperature resistance, acid and alkali resistance, moisture resistance, fire resistance, etc., and combines the functions of stickers and plywood into one, saving decoration costs and labor costs, and is wid...
