Embodiment 1

[0046] A preparation process of a pressure-resistant composite plate in this embodiment includes the following steps:

[0047] Step 1: put agricultural waste straw and wood processing waste into a pulverizer for crushing, add the mixed augmentative plant extracts into a steamer, keep warm at a temperature of 50°C for 5 hours, and then carry out pressure cooking for 1 hour, and then heat grind Machine grinding, put into a closed pressure container, keep it under 2Mpa air pressure for 10 minutes, open the closed container instantly, filter the mixed material, roll and knead the mixed material, add 4 parts by weight of tetrabutyl titanate after drying, no 40 parts of water ethanol, 10 parts of magnesium sulfate solution with a mass fraction of 35%, and 15 parts of polyvinyl alcohol in an impregnating solution, stirred and soaked for 20 minutes, drained and set aside;

[0048] Step 2: Pulverize shavings and cardboard fibers, and add 50 parts by weight of water, 20 parts of caustic...

Embodiment 2

[0067] A preparation process of a pressure-resistant composite plate in this embodiment includes the following steps:

[0068] Step 1: Put agricultural waste straw and wood processing waste into a pulverizer for crushing, add the mixed augmentative plant extracts into a steamer and keep it warm at a temperature of 70°C for 7 hours, then carry out pressure cooking for 2 hours, and then heat grind Machine grinding, put into a closed pressure container, keep it under 2Mpa air pressure for 10 minutes, open the closed container instantly, filter the mixed material, roll and knead the mixed material, add 6 parts by weight of tetrabutyl titanate after drying, no 50 parts of water ethanol, 15 parts of magnesium sulfate solution with a mass fraction of 35%, and 20 parts of polyvinyl alcohol in an impregnating solution, stirred and soaked for 30 minutes, drained and set aside;

Abstract

The invention relates to the technical field of board manufacturing, in particular to a preparation process of pressure resisting composite boards. The process comprises the steps of preparation of basic fibers, preparation of enhanced fibers, preparation of binders, preparation of inflaming retarding reinforcing agents, preparation of curing agents, material mixing and board preparation. According to the board preparation method, waste is recycled, the process is environmentally friendly, the prepared boards are good in mechanical strength and have excellent mould proof and inflaming retarding properties, no harmful gas is released, the production process is controllable, and the boards are free of poison and harm, are suitable for volume production and have great practical value and goodapplication prospects.

Description

technical field [0001] The invention relates to the technical field of modern papermaking, in particular to a preparation process of a pressure-resistant composite plate. Background technique [0002] On the one hand, wood has always been favored by humans. Its natural texture, texture, structural mechanical properties, and ease of processing are irreplaceable by other materials, and it is widely used in furniture manufacturing and building materials industries. However, the material of some wood, especially plantation wood, cannot meet the needs of the public. For example, its structure is relatively loose, low density, easy to be eaten by insects, bacterial erosion, acid, alkali and weathering degradation, etc. Therefore, the application of composite boards was born, and now Some raw materials in the board are too single, and the prepared board has poor pressure resistance and mechanical properties. [0003] On the other hand, wood flame retardant is a method of improving...
