Straw fiberboard

Abstract

The invention discloses a straw fiberboard. The straw fiberboard comprises, by weight, 50 to 60 parts of polyethylene resin powder, 30 to 35 parts of polyvinyl chloride resin powder, 20 to 22 parts ofstraw powder, 5 to 10 parts of calcium powder, 7 to 11 parts of ACR, 4 to 6 parts of a calcium zinc composite stabilizing agent, 0.5 to 0.6 part of polyethylene wax, 1 to 1.5 parts of stearic acid, 2to 3 parts of paraffin, 5 to 7 parts of magnesium oxide, 3 to 5 parts of magnesium chloride, and 16 to 20 parts of urea-formaldehyde resin. According to a preparation method, straw waste is taken asa raw material, and better combination with resin plastic is achieved without modification, so that full utilization of straw is realized, and the strength of conventional bamboo fiberboards is achieved. Straw powder high efficiency recycling is realized, and pollution on the environment by the conventional processing method of crop straw is avoided.

Description

technical field [0001] The invention relates to the technical field of integrated wallboards, in particular to a straw fiberboard. Background technique [0002] Fiberboard refers to a wood-based panel made of lignocellulosic fibers interwoven and using their inherent adhesive properties. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., and has a wide range of uses. [0003] Existing fiberboards are all made of bamboo fiber and wood fiber, and the materials used are wood and bamboo. With the development of society, the country attaches great importance to the environment, and the supply of wood and bamboo continues to decrease, making the cost of fiberboard unsatisfactory. reduce.

Problems solved by technology

[0003] Existing fiberboards are all made of bamboo fiber and wood fiber, and the materials used are wood and bamboo. With the development of society, the country attaches great importance to the environment, and the supply of wood and bamboo continues to decrease, making the cost of fiberboard unsatisfactory. reduce

[0004] my country is a large agricultural country, and there is a large amount of crop straw waste every year. Due to the low recycling efficiency of straw, a large amount of straw cannot be recycled, but is simply burned. Straw incineration refers to the destruction of crop straw by fire. A kind of behavior; straw burning causes smog weather and produces a large amount of toxic and harmful substances, which poses a threat to the health of humans and other organisms; and straw burning is very easy to ignite the surrounding combustibles. Once a wheat field fire is triggered, it is often difficult to control , causing economic loss

Especially in the vicinity of mountains and forests, the consequences are even more unimaginable; straw burning also destroys the soil structure, resulting in a decline in the quality of farmland. The balance of this biological system is changed, the physical properties of the soil are changed, soil compaction is aggravated, soil fertility is destroyed, drought is exacerbated, and the growth of crops is thus affected
