Technical field
The invention belongs to a kind of preparation method who produces hardwood plate, that be specifically related to is a kind of preparation method who produces hardwood plate with reclaimed rubber.
Background technology
The natural timber inadequate resource has become a worldwide problem, and China is the country that timber resources is extremely poor especially, therefore, seeks new wood substitutes, creates " second forest ", has become the problem that presses for solution.
On the other hand,, annual produce a large amount of rubber and plastic wastes, just can produce about 5,000,000 every day as the waste rubber tire whole world only along with the widespread use of product of rubber and plastic.The waste ' s reclamation deficiency has not only caused huge waste, and has caused the overcut of forest, causes a series of society and ecological problem thus.
Under above-mentioned background, the exploitation of wood plastic composite and suitability for industrialized production have been subjected to extensive attention in recent years.The exploitation wood plastic composite helps alleviating the pressure that is becoming tight timber day, helps conserving forests and the comprehensive utilization of plastic refuse.But wood plastic composite exists poor flexibility, problem such as not anti-skidding, and has series of advantages with the vulcanite sheet material of reclaimed rubber production, some performance even be better than timber, as the distortion that do not absorb water, do not ftracture, do not damage by worms, corrosion-resistant, antistatic etc.In addition, hardwood plate is difficult for creep strain, shock-resistant and wet and slippery property is good.
Goods such as waste and used rubber tyre reclaim comprehensive utilization and mainly obtain reclaimed rubber and rubber powder.Rubber powder is a kind of material of being made up of multiple materials such as rubber, carbon black, tenderizer and vulcanization accelerators that contains crosslinking structure, and therefore, rubber powder can only use as weighting agent, to reduce the consumption of rubber.In addition, vulcanized rubber powder is inertia, and is relatively poor with the consistency of material of main part, causes material property to descend easily if directly or too much fill.Adopt reclaimed rubber then not have above problem substantially as the raw material of hard plate material.
General rubber product has excellent elasticity, but poor rigidity, needs certain rigid as the sheet material of structured material, and this just requires rubber to have higher cross-linking density.Increase sulfur consumption and help to improve the cross-linking density of rubber, but when adopting common rubber, increase with sulfur consumption and can produce sulfur blooming, influence the dispersing uniformity of sulphur in sizing material, make the quality reduction of cross-linked rubber as raw material.The present invention adopt waste and used rubber tyre etc. for the reclaimed rubber of raw material production as raw material because its molecular weight is lower, can increase the solvability of sulphur, make sulphur better dispersed in sizing material, thereby improve the performance of hardwood plate.
Because the cross-linking density of vulcanite sheet material is higher, the saturation ratio of polymer molecular chain is increased, thereby improved the ageing-resistant performance of vulcanite goods, prolonged the work-ing life of goods.
In addition, can add glasscloth, to improve the intensity of the hardwood plate that adopts reclaimed rubber production as strongthener.
