The preparation method of hardwood plate: at first make reclaimed rubber through desulfurization with waste rubber product, then will be mixing evenly by 0.1~5 part of 100 parts of reclaimed rubber, 10~20 parts of vulcanizing agents, 0.3~5 part of vulcanization accelerator, 0.1~10 part in activator, 1~80 part of weighting agent, 0.1~1.5 part in anti-aging agent, softening agent in weight part with kneader, send into vulcanizing press compression molding, sulfuration again, 140~180 ℃ of curing temperatures, pressure 20~40MPa, 20~60 minutes time, make needed vulcanite sheet material.

Hardwood plate of the present invention is that the reclaimed rubber that adopts waste rubber goods to obtain through desulfurization is made, have very high MOR and modulus, make it can be used as structured material, to substitute traditional hard wood, hardwood plate also has excellent ageing-resistant performance, long service life.

The hardwood plate applied range, as being used as the substitute of timber under various conditions, wherein be specially adapted to substitute outdoor garden landscape decoration timber, as as outdoor floor, fence, handrail, flower case, rubbish container, wayside pavilion, log cabin, balcony, stair, balcony etc., goods have under the condition of exposing to the sun and rain that the creep strain of being difficult for, shock-resistant and wet and slippery property are good, the distortion that do not absorb water, do not ftracture, do not damage by worms, series of advantages such as corrosion-resistant.In addition, the raw material sources of this hardwood plate are in waste rubber goods, and product cost is low, and improved the utilization ratio of waste rubber goods.

Embodiment

The influence that the present invention mainly is subjected to vulcanizing agent and promotor kind and consumption, weighting agent kind and consumption etc. with the intensity and the modulus of the vulcanite sheet material of reclaimed rubber production, and can change its intensity and modulus by regulating above-mentioned factor.

Vulcanizing agent sulphur can make polymkeric substance change netted macromole into by long chain molecule, because the large usage quantity of sulphur in the vulcanite goods, in order to obtain high-quality cross-linked rubber, the uniform distribution of sulphur in sizing material is extremely important.Adopt reclaimed rubber as basic glue, can increase the solvability of sulphur, make the dispersiveness of sulphur in sizing material better, thereby improve the performance of hardwood plate.

Vulcanization accelerator can promote the sulfuration of rubber, reduces the needed temperature of sulfuration, shortens curing time, and improves the physical and mechanical properties of cross-linked rubber.A kind of in 2-benzothiazolyl mercaptan, dibenzothiazyl disulfide, vulkacit D and the tetramethyl-thiuram disulfide or their mixture can be used as the vulcanization accelerator of reclaimed rubber.
