Embodiment

[0023] A kind of montmorillonite-modified waterproof and flame-retardant biomass board and preparation method thereof, prepared from the following raw materials in parts by weight (g):

[0024] Rice straw 45, sulfate wood pulp 6, carboxy-modified silicone oil 5, gelatin 7, nano-montmorillonite 10, emulsifier OP-10 1, liquid paraffin 4, rosin 3, polyacrylic acid 6, melamine phosphate 5, boric acid 3, 4 hydrotalcites, 1 pine oil, appropriate amount of ethanol and distilled water.

[0025] A montmorillonite-modified waterproof and flame-retardant biomass plate and a preparation method thereof, characterized in that, the steps are as follows:

[0026] a. Dry the rice stalks and cut them into 10-20mm pieces with a pulverizer, soak them in water for 2 days at room temperature,

[0027] Mechanically disintegrate into fibers with a length of 1-5mm, add kraft wood pulp, mix evenly, pour into a beater, and divide into filaments to make the beating degree 25-35 0 SR, slowly stir and ad...

Abstract

The invention discloses a montmorillonoid modified waterproof and flame-retardant type biomass plate and a preparation method thereof. The montmorillonoid modified waterproof and flame-retardant type biomass plate is characterized in that rice straws, sulfate wood pulp, carboxyl modified silicone oil, gelatin, nano montmorillonoid, an emulsifier OP-10, liquid paraffin, rosin, polyacrylic acid, melamine phosphate, boric acid, hydrotalcite, pine oil and the like are used as raw materials. The preparation method comprises the following steps: adding the sulfate wood pulp in the rice straws and carrying out fibrillation; adding the carboxyl modified silicone oil to carry out reinforced modification; and adding the pine oil as a foaming agent. Rosin powder is used as a filling agent, and can be used as an adhesive after being melted at high temperature; by nano montmorillonoid modification, the mechanical property and the size stability of the plate are improved remarkably; a micro-capsule waterproof agent is prepared by single cogulation; a melamine phosphate-polypropylene salt-borate flame retardant is prepared, and by the synergistic effect of the melamine phosphate- polypropylene salt-borate flame retardant and the hydrotalcite, the flame-retardant effect is good; and the montmorillonoid modified waterproof and flame-retardant type biomass plate is obtained.

Description

technical field [0001] The invention relates to a preparation method of a biomass board, in particular to a waterproof and flame-retardant biomass board modified by montmorillonite and a preparation method thereof. Background technique [0002] my country is a big rice-producing country with rich rice straw resources, which can be used to make biomass panels, relieve the pressure on wood supply, replace some wood products and plastic products, reduce the pollution of plastics to the environment, and make rice straw resources more efficient. effective use. [0003] In Zhang Jin’s postgraduate dissertation "Using Rice Straw to Make Completely Degradable Biomass Sheet", using rice straw as the raw Physical methods, after chopping, soaking, grinding, hot pressing and other processes, a biomass plate with a certain strength is made. There is no addition of any chemical reagents in the process of making boards, which saves costs, and can be completely degraded and absorbed by the...
