Abstract
A high-strength waste tire rubber powder modified bamboo fiber board comprises, by weight, 162-164 parts of bamboo fibers, an appropriate amount of a 0.2% sodium hydroxide solution, 16.2-16.7 parts of soybean protein isolate, 1.5-1.6 parts of an anti-corrosion agent, 1.2-1.3 parts of 2,2,2-trifluoroethyl acrylate, 7-8 parts of waste tire rubber powder, 0.2-0.3 part of cumene peroxide, 1-1.5 parts of nanometer tungsten trioxide and 1-2 parts of a carbon nanofiber. The bamboo fiber board is modified through the 2,2,2-trifluoroethyl acrylate and the waste tire rubber powder, and therefore the surface of the board has good hydrophobicity, and the mechanical property of the bamboo fiber board reaches the national standard of GB/T11718-2009 medium-density fiber boards of a common type in a dry state, a furniture type or a furniture type in an outdoor state. By using the nanometer tungsten trioxide and the carbon nanofibers, the abrasion resistance and the tensile strength of the board are improved; and by using soybean protein isolate adhesive, the high-strength waste tire rubber powder modified bamboo fiber board is environment-friendly and healthy.
Description
Technical field
The present invention relates to bamboo fiberboard and manufacture field, particularly relate to a kind of high strength using rubber powder of waste tire modified bamboo fiberboard and preparation method thereof.
Background technology
Fiberboard structure is even, surface smoothing polishing, has good processing characteristics, is therefore widely used in furniture manufacturing industry and building industry.The primary raw material preparing fiberboard is at present wood fibre and urea-formaldehyde resin adhesive.Along with the transition of the forest reserves is cut down, how to ensure sufficient raw material supplying, become an important society and economic problems.In addition, Lauxite derives from non-renewable fossil resources, easily discharges free formaldehyde, serious environment pollution under hygrothermal environment, and harm humans is healthy.Along with crude oil price rise steadily and people to the growing interest of self and environmental security, this problem becomes more severe.
Bamboo grows is fast, output is high, and compared with timber, having the features such as intensity is high, good toughness, is the desirable feedstock of fiberboard.China's bamboo resource enriches, and has bamboo 40 to belong to kind more than 500, area 8,000,000 hm
2, account for 40% of world's bamboo grove area, thousands of family of existing bamboo processing factory, bamboo grove year cutting reach 400,000,000 strains, 1,200 ten thousand t, in Bamboo processing enterprise, have a large amount of fiber residue go out of use and be not fully utilized.
Soybean protein is the byproduct of fats and oils processing, abundance.Modified soy protein adhesive is nontoxic, is a kind of environmentally friendly product.Sun etc. utilize urea, SDS, SDBS, guanidine hydrochloride to Soybean Protein Modification, improve its adhesive property.Hong Yiqian etc. utilize sodium hydroxide solution to soybean protein isolate modified, obtain adhesive property preferably adhesive.Li Yonghui etc. use the soybean isolated protein adhesive of SDS modification, significantly improve its adhesive property at glued board, weather resistance and water resistance." the bamboo fiberboard performance based on modified soy protein adhesive " literary composition utilizes modified soy protein adhesive to produce bamboo fiberboard, the MOR of this bamboo fiberboard reaches 16.5MPa, elastic modelling quantity 1032.6MPa, tensile strength 10.4MPa, thickness swelling 31.0%.
In recent years, China's rubber sources is in short supply, the natural rubber that annual import is a large amount of and synthetic rubber, and tire consumes more than 70% of rubber total quantity consumed; Junked tire becomes black pollution, China's junked tire output 2004 1.12 hundred million, 2006 1.5 hundred million, 2008 about 2.07 hundred million, 2009 2.33 hundred million, within 2010, be 2.56 hundred million.Junked tire is mainly used in tyre rebuilding, rubber powder utilization, the original shape transformation of the way, reclaimed rubber, thermal cracking utilization and fuel.
By waste rubber powder alkali treatment, with wood materials compound, can improve the performances such as the waterproof of material, shockproof, heat insulation, sound insulation, report waste rubber powder being used for bamboo fiberboard does not also have.
