example 1

[0024] In parts by weight, add 5 parts of chitosan, 4 parts of gluten, and 100 parts of water to the beaker, stir and mix with a glass rod for 15 minutes, let it stand for swelling at room temperature for 4 hours, and then move the beaker into the digital display. Speed-measuring and constant-temperature magnetic stirrer, at a temperature of 95°C and a speed of 500r / min, stir and dissolve at a constant temperature for 40 minutes, then remove the beaker, let it stand and cool to room temperature naturally, and then add inorganic adhesive 0.8 times the water quality to the beaker Mix with a glass rod for 45 minutes to obtain a viscous slurry; in parts by weight, take 30 parts of straw with a mesh size of 10 to 20 mesh, 30 parts of straw with a mesh size of 30 to 40 mesh, and 50 parts of straw with a mesh size of 50 ~80 mesh straw, stir and mix in a mixer for 45min to get straw scraps, then mix the obtained straw scraps with biogas slurry at a mass ratio of 10:1, spread them evenl...

example 2

[0026]In parts by weight, add 3 parts of chitosan, 2 parts of gluten powder, and 90 parts of water to the beaker, stir and mix with a glass rod for 10 minutes, let it stand for swelling at room temperature for 2 hours, and then move the beaker into the digital display. With a speed-measuring and constant-temperature magnetic stirrer, at a temperature of 90°C and a speed of 300r / min, stir and dissolve at a constant temperature for 20 minutes, then remove the beaker, let it stand and cool down to room temperature naturally, and then add inorganic adhesive 0.6 times the water quality to the beaker Mix with a glass rod for 30 minutes to obtain a viscous slurry; by weight, take 20 parts of straw with a mesh size of 10 to 20 mesh, 20 parts of straw with a mesh size of 30 to 40 mesh, and 30 parts of straw with a mesh size of 50 ~80 mesh straw, stir and mix in a mixer for 30 minutes to get straw scraps, then mix the obtained straw scraps with biogas slurry at a mass ratio of 8:1, and s...

Abstract

The invention relates to a preparation method of an inorganic straw composite particle board, and belongs to the technical field of artificial boards. The preparation method comprises the following steps of firstly agitating and mixing chitosan, vital gluten and water, then standing, swelling, afterwards, heating to raise a temperature, agitating and dissolving at a constant temperature, adding an inorganic adhesive after naturally cooling to a room temperature, agitating, mixing, so as to obtain viscous slurry, and afterwards, agitating and mixing a straw particle and a rice hull particle, so as to obtain a mixed particle; atomizing the viscous slurry, then sprinkling into the mixed particle, after the sprinkling is finished, continuously agitating and mixing, so as to obtain a wet material, spreading the wet material to be a board blank, then carrying out hot pressing treatment, then drying after carrying out high-pressure steam curing and natural curing, and discharging. The inorganic adhesive is prepared from dicalcium silicate, tricalcium silicate, tricalcium aluminate, magnesium chloride and the like. The particle board prepared by the preparation method is high in mechanical strength, and can be used as a load-bearing structural component.

Description

technical field [0001] The invention relates to a preparation method of an inorganic straw composite particle board, which belongs to the technical field of artificial boards. Background technique [0002] At present, my country's wood-based panel production ranks first in the world, among which particle board, fiberboard and plywood are listed as the "three major boards" in wood-based panel products. Particle board is a wood-based panel made of wood chips as the main raw material, resin and waterproofing agent as auxiliary materials, and pressed under high temperature and high pressure conditions. Compared with plywood, particle board production mainly uses small-diameter wood, thinning wood, and branch wood as raw materials, and has the characteristics of wide material sources and high resource utilization. [0003] At present, particle board has been widely used in furniture manufacturing, interior decoration, etc., but particle board is composed of small unit fragments,...
