Technical field
The present invention relates to technical field of polymer materials, particularly relate to a kind of blown rigid imitated wood material and preparation side thereof Method and application.
Background technology
Timber and wood plank have purposes the most widely in modern society.But owing to the forest reserves are limited, for protecting Protecting natural environment, reduce the use of natural timber, now with the synthetic material succedaneum of various performances, major product has:
1) Wood-plastic material: use wood powder, the material such as straw stalk powder and plastic pellet to be mixed.Its feature is that wood powder etc. can make With waste and scrap or offal etc., plastics can use reclaiming plastics.There is not timber intrinsic defect such as knot, Testudinis in product Split, warpage, rotten etc..Shortcoming is that wood powder processes requirement height, and prior art can not reach satisfied effect, and wood powder, bamboo powder The poor heat stability of class wood fibre, product is the most mouldy, and fungus grows, dilatancy etc. of making moist.Product surface effect simultaneously The most coarse, imitation wood poor effect.Secondary recovery utilization rate is the highest.
2) the plastics simulative synthetic wood such as PVC, PE, mainly by recyclable waste or used plastics, re-works after granulation Become imitation wood product.Shortcoming is that product is harder, and fragility is big, easily snaps off, shorter for outdoor products service life, general 1-2 Rear performance is decreased obviously, and weatherability is poor.
Summary of the invention
For the technological deficiency overcoming prior art to exist, the present invention provides a kind of blown rigid imitated wood material and preparation side thereof Method and application, improve waterproof and dampproof performance, reduces density of material and fragility, has that heat stability is good, creep resisting ability is good, weather-proof Property good, improve mechanical strength and increasing the service life, and material be without wood substance component, degradable, low-carbon environment-friendly.
The technical solution that the present invention uses is:
A kind of blown rigid imitated wood material, including the raw material of following mass percent: the maleic anhydride of 40%～45% connects Branch hydrogenated styrene-butadiene block copolymer, the high styrene rubber of 18%～23%, the high-density polyethylene of 15%～20% Alkene, the butadiene rubber of 4%～6%, the nitrile rubber of 8%～10%, the processing aid of 7.5%～10%.
Preferably, described processing aid includes the component of following mass percent: the crosslink agent DCP of 1.5%～2.0%, The stearic acid of the calcium carbonate of zinc oxide, 0.5%～1.0%, 1.5%～2.0%, 0.5%～1.0% of 2.5%～3.0% Inorganic or organic toner, 0%～the titanium dioxide of 1.0% and the blowing agent AC of 0%～1.5%, each component of described processing aid Percentage ratio radix is the raw material gross weight of this imitated wood material.
The present invention also provides for the preparation method of a kind of blown rigid imitated wood material, specifically includes following steps:
1) get the raw materials ready: weigh maleic anhydride grafting hydrogenated styrene-butadiene block copolymer, the high benzene of described parts by weight Ethylene rubber, high density polyethylene (HDPE), butadiene rubber, nitrile rubber and each processing aid；
2) banburying: first the maleic anhydride of described parts by weight is grafted hydrogenated styrene-butadiene block copolymer, high benzene Ethylene rubber, high density polyethylene (HDPE), butadiene rubber, nitrile rubber, calcium carbonate and stearic acid put into banbury, then put down refining hammer Mixing, until promoting refining hammer when banburying temperature is 105 DEG C, then put into the zinc oxide of described parts by weight, peroxidating diisopropyl Benzene and other processing aids, put down refining hammer, promotes refining hammer, discharging when banburying temperature is 120 DEG C；
3) mill: material is served mill with stack pallet, shears mixing again；
4) slice: according to mould size length and width equivalent slice；
5) sulfuration: by step 4) sheet material load onto 1000T vulcanizer, sulfuration air pressure 0.8MPa, cure time 30min～ 40min；
6) having vulcanized rear steam off, be passed through cold water cooling, after cooling down 30 minutes, die sinking goes out finished product.
The present invention furthermore provides blown rigid imitated wood material at outdoor floor, fence, handrail, flower case, refuse bin, cool The application in booth, corridor, log cabin, balcony or building.
Beneficial effects of the present invention: the present invention uses SEBS-g-MAH, HDPE, HSR, NR and NBR to be blended in specific proportions, And add the CaCO of special ratios3With processing aids such as DCP, each component compatibility is good, is substantially improved waterproof and dampproof performance and drops Low density of material and fragility, improve mechanical strength and increasing the service life, the imitated wood material product prepared have heat stability good, Creep resisting ability is good, weatherability is good, and environmental stress crack resistance is good, good processability, combines fastening with screw etc., and has relatively High MOR and fatigue resistance, durable in use and degradable.The another present invention is without wooden and plant fiber component, and passes through Inorganic or organic toner allotment reaches the effect of imitation wood, while strengthening its perception, it is to avoid use wood powder to reduce timber Use, beneficially environmental conservation, low-carbon environment-friendly, and reduce the danger of the processes such as production and application.The blown rigid of the present invention is imitated Wood material can be used as indoor decorative board at home, it is possible to is used as outdoor garden landscape decoration materials, such as outdoor floor, fence, Handrail, flower case, refuse bin, wayside pavilion, corridor, log cabin, balcony or building.
