Environment-friendly flame-retardant straw plate and preparation method thereof

Abstract

The invention discloses an environment-friendly flame-retardant straw plate. The environment-friendly flame-retardant straw plate is prepared from crop straw, bamboo charcoal fibers, glutinous rice flour, an aluminic acid ester coupling agent, polyanionic cellulose, diatomite, a magnesium hydroxide flame retardant, silica fume and deionized water. The straw plate has the high strength, the flame retardant property is good, various properties all meet the corresponding requirements, green and environmental protection are achieved, zero formaldehyde emission is achieved, the oxidation resistanceis high, the mass is low, the high additional value of the crop straw is increased, straw burning and tree cutting are reduced while the production cost is reduced, and the market application prospect is very wide.

Description

technical field [0001] The invention relates to the technical field of furniture panels, in particular to an environment-friendly flame-retardant straw panel and a preparation method thereof. Background technique [0002] At present, the manufacture of domestic furniture boards mostly uses wood materials such as board scraps, miscellaneous wood, and sawdust. 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. , so looking for new material panels to replace wooden panels has become the first choice in the panel market. [0003] As a by-product of agricultural production, crop straw not only has a large quantity, but also has high cellulose and lignin content, so it becomes the first choice to replace wood panels, reducing straw burning and tree felling while reducing production costs. Although some domestic enterprises and scientific research institutions have m...

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 for them are also increasing in the market. As a non-metallic material, straw boards have fatal shortcomings such as fire resistance, heat resistance, and moisture resistance, and the existing straw boards are added A large amount of adhesive, once exposed to an open flame, it is easy to produce thick smoke and toxic gases, hindering people from escaping
