Preparation method of high-strength environment-friendly antibacterial straw board

Abstract

The invention mainly relates to the technical field of furniture board processing, and discloses a preparation method of a high-strength environment-friendly antibacterial straw board. The preparation method comprises the following steps of straw cleaning, straw fermentation, straw drying, raw material mixing, primary hot pressing, board maintenance, secondary hot pressing and post-treatment; andaccording to the preparation method of the high-strength environment-friendly antibacterial straw board, the board is prepared by taking a straw as a main raw material, waste materials are changed into things of value, the environment is protected, the raw material sources are wide, the price is low, the production cost of the board is reduced, the prepared board is high in strength, does not contain formaldehyde, is effectively antibacterial and anti-mildew, improves the processing performance and the service life of the board, and enlarges the application range of the straw board.

Description

technical field [0001] The invention mainly relates to the technical field of furniture plate processing, in particular to a preparation method of a high-strength, environment-friendly and antibacterial straw plate. Background technique [0002] At present, most of the wood-based panels in our country are made of scraps, scraps, shavings, wood chips and other waste materials produced in the wood processing process. There are fewer and fewer, and the price is getting higher and higher, which cannot meet the needs of panel production. Therefore, it is necessary to find new materials to prepare panels to ease the pressure on timber felling and demand in our country. [0003] China is a large agricultural country. Straw is a by-product of agricultural production. It has a large output, low cost, and is rich in cellulose. Production cost; however, the surface layer of straw has a layer of waxy structure, especially wheat straw, rice straw and corn straw. At present, the existing...

Problems solved by technology

[0002] At present, most of the wood-based panels in our country are made of scraps, scraps, shavings, wood chips and other waste materials produced in the wood processing process. Less and less, the price is getting higher and higher, which cannot meet the needs of panel production, so it is necessary to find new materials to prepare panels to ease the pressure on my country's timber felling and demand

[0003] China is a large agricultural country. Straw is a by-product of agricultural production. It has a large output, low cost, and is rich in cellulose. Production cost; however, the surface layer of straw has a layer of waxy structure, especially wheat straw, rice straw and corn straw. At present, the existing method of removing the waxy structure is grinding, which is inefficient and expensive, and the dust generated is easy Explosion, the existing patent document CN107498685A discloses a green and environmentally friendly production method for rice straw boards. The straw straw is not polished, and the chemical raw materials and adhesives that are similar or similar to the waxy structure of the straw straw are selected. The chemical raw materials include silicone resin, Alkaline oxides, silanol esters, polysilanol esters, sodium salts of silanol esters, sodium salts of polysilanol esters, and borax, etc. Adhesives include melamine formal, polyvinyl butyral, casein, Oxidized starch, starch adhesive, polyvinyl alcohol, phenolic resin, epoxy resin and polyurethane, etc., add a large amount of chemical raw materials and adhesives, and the prepared board will be aged after a period of use, and it is easy to mix with chemical raw materials and The adhesive is detached, so the strength and durability of the plate prepared by the patent document are low; the existing patent document CN110078975A discloses a preparation process for a recycled plate from crop straw, which specifically discloses that the straw is modified and then used. The preparation process is to crush rice straw, corn straw, wheat straw, rape straw, etc., add ethanol and polyvinyl alcohol successively, and undergo high-temperature and high-pressure steam explosion treatment. Ethanol and polyvinyl alcohol are used as chemical raw materials, and a large amount of straw is modified. A large amount of chemical reagents are still needed, and it will also cause certain harm to the environment; therefore, a high-strength, environmentally friendly and antibacterial straw board made of straw is needed
