Embodiment 1

[0038] Embodiment 1: A kind of manufacturing method of high-strength environmental protection plate, comprises the following steps:

[0039] Step 1. Wood pretreatment

[0040] Mix 800 parts by weight of coniferous material and 400 parts of crop straw evenly, and soak in a dilute hydrochloric acid solution with a temperature of 40° C. and a concentration of 20% for 1 hour; take it out, rinse it for 30 minutes, and then soak it in a temperature of 40°C, 2 hours in a caustic soda solution with a concentration of 20%; take it out and rinse until its pH is neutral to obtain crude fiber;

[0041] Step 2, the preparation of main ingredient

[0042] First add 60 parts of barite powder in parts by weight to the crude fiber obtained in step 1, stir it and divide it into 3 equal parts, and then grind it into three kinds of fiber filaments with different fineness by a refiner, which are respectively:

[0043] The first fiber silk, the fineness is 10-40 mesh;

[0044] The second fiber s...

Abstract

The invention discloses a manufacturing method of a high-intensity environmental-friendly board. The manufacturing method comprises the following steps: pretreatment of timber, preparation of main material, preparation of sizing agent, preparation of auxiliary material, preparation of base material and preparation of board material. By fully using tailings of an industrial and mineral industry, tailings of a timber processing industry, crop straw wastes and other natural raw materials, the purpose of consuming the least resource and energy is realized; meanwhile, a plurality of inorganic modified materials are added, and formed to be a high-intensity ecological environmental-friendly board through low-temperature die pressing in a certain ratio and self-condensing reaction of the material; the whole production process is low-carbon, environmental-friendly and energy-saving; the produced board is fireproof, insect-prevention, waterproof, high-intensity fracture resistance, aging resistance, and free from formaldehyde, methylbenzene and other harmful matters and also free from radioactive contamination; every performance quality is excellent.

Description

technical field [0001] The invention belongs to a production method of building boards, in particular to a production method of high-strength environment-friendly boards. Background technique [0002] With the rapid development of our country's economy and the continuous improvement of the urbanization rate, the number of logs is getting less and less, and the price is getting higher and higher. At the same time, logs do not have the advantages of flame retardancy, corrosion resistance and high hardness, so the quality is stable. , high environmental protection level, and environmentally friendly panels with safe and flame-retardant functions have a broad market space. [0003] In the future, the rapid development of my country's real estate industry, furniture, interior decoration, packaging and other industries and the completion and production of fast-growing industrial timber forest raw material bases will drive the steady growth of fiberboard demand and export volume, a...
