A production method of a plant multi-fiber modified board with the function of purifying air

Abstract

The invention discloses a production method for a plant multi-fiber modified board with an air purifying function. The production method is characterized in that multiple plant fibers are extracted and mixed according to the proportion, water is added to the plant fibers, the plant fibers are made into anion pulp, then modified cationic starch is added, the plant fibers are rearranged by polymerizing zwitterions, a coarse cotton cloth sizing agent flowing mode is used for dehydration so that a wet fiberboard can be formed, then purifying structure films doped with nanometer titanium dioxide are formed in the surfaces of wet fibers, rolled, pressurized and laminated to be manufactured into the wet fiberboard of the needed thickness, and finally the wet fiberboard is dried. The purifying films can decompose harmful substances such as formaldehyde and methylbenzene under light condition. The wet fiberboard can be modeled at will, and can be made into boards with different physical properties; continuous forming is adopted in the production process, and the yield is high; selected raw materials are wide, most raw materials are abandoned materials, and resources are saved; the different fibers are combined through hydrogen bonds, harmful ingredients are avoided, and the board is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of fiber boards, in particular to a production method of a plant multi-fiber modified board with the function of purifying air. Background technique [0002] With the rapid development of the domestic property market and furniture industry, the fiberboard industry as a basic material has risen rapidly. In 2014, the total output of fiberboard in my country was 69.2383 million cubic meters, and the total market volume is huge. There are two types of fiber boards currently on the market, one is a single sheet that is spliced ​​by gluing, such as wood or bamboo. The other is the traditional fiberboard (also known as density board), which is made by mechanically crushing raw materials of different materials into small particles, applying urea-formaldehyde resin or other suitable adhesive preparations, and then heating and pressing. Divided into low-density fiberboard (less than 0.65g / cm 3 ), medium density fibe...

Problems solved by technology

Splicing boards not only consume a lot of forest resources, but also have single performance, hard and brittle texture, and narrow application range; while traditional fiberboards have the advantages of uniform material, small vertical and horizontal strength differences, and are not easy to crack, but also have many disadvantages: 1. 1. The crushing, heating and pressure gluing process is not easy to shape, which makes the shape of the fiberboard single; 2. The texture of the traditional fiberboard is single, hard and brittle, and has no flexibility; 3. The thickness and density of the traditional fiberboard are relatively large, thick; 4. The output is low and High resource consumption; 5. The glue used for bonding mostly contains harmful components such as formaldehyde, which is not environmentally friendly; 6. The traditional fiberboard has a single function
