Mildewproof, mothproof and bacteriostatic straw plate and preparation method thereof

Abstract

The invention discloses a preparation method of a mildewproof, mothproof and bacteriostatic straw plate. The preparation method comprises the following steps: smashing crop straws into particles, soaking the particles in sodium hydroxide solution and sulfuric acid solution to obtain straw fibers, mixing the straw fibers with rosemary powder, bamboo charcoal fiber, expanded vermiculite and kieselguhr separately to obtain a surface layer mixture, mixing the straw fibers with coconut carbon fiber and green bean starch to obtain a core layer mixture, paving the surface layer mixture into a die according to the odd number layer principle, paving the core layer mixture into the die according to the even number principle, and carrying out drying, thermo-compression formation, cooling, demoulding,maintaining, edge cutting and packaging to obtain a finished product. The mildewproof, mothproof and bacteriostatic straw plate is non-toxic, tasteless, formaldehyde-free, and environmental-friendly,has higher strength, is high in fireproof performance and humidity resistance, is light in weight, facilitates transportation and construction installation and can enhance memory and refresh throughrosemary. Various performance of the mildewproof, mothproof and bacteriostatic straw plate meets corresponding requirements. Furniture made of the mildewproof, mothproof and bacteriostatic straw platecan effectively prevent mildew, acarid, resist bacteria and can automatically adjust the indoor humidity.

Description

Technical field [0001] The invention relates to the technical field of furniture boards, in particular to a mould-proof, insect-proof and antibacterial straw board and a preparation method thereof. Background technique [0002] At present, most of the domestic furniture board manufacturing uses wood scraps, miscellaneous wood, sawdust and other wood raw materials. However, with the lack of wood resources and the introduction of environmental protection policies, the cost of wood-based boards is becoming more and more expensive Therefore, it has become the first choice in the plate market to find new material plates to replace wooden plates. [0003] As a by-product of agricultural production, crop stalks are not only large in quantity, but also have high cellulose and lignin content, which makes them the first choice to replace wooden boards, reducing production costs while reducing straw burning and tree felling. Although some domestic companies and scientific research institutio...

AI Technical Summary

Problems solved by technology

Although some domestic enterprises and scientific research institutions have made many attempts to use crop straw to produce boards, the boards produced have defects in strength, flame retardancy, water resistance and environmental protection. The adhesive used in the process has a strong odor and excessive formaldehyde content, which not only pollutes the environment, but also endangers human health, and the bonding strength does not meet the standard requirements.

[0004] With the vigorous promotion and use of straw boards, the performance requirements of straw boards are also increasing day by day. As a non-metallic material, straw boards have fatal shortcomings such as fire prevention and moisture resistance, and a large number of bacteria, Mildew spots, mites, etc. People stay in this environment for a long time, which seriously damages human health
