Description
Technical field
The present invention relates to Material Field, specifically a kind of TPE gross porosity foam material and preparation method thereof.
Background technology
Thermoplastic elastomer TPE(Thermoplastic Elastomer) be a kind of snappiness with rubber, high strength, high resilience, has again the material of feature that can injection molding.There is environment-protecting asepsis safety, durometer level is wide, has good tint permanence, soft-touch, weathering resistance, fatigue resistance and temperature tolerance, processing characteristics is superior, need not vulcanize, can recycle and reduce costs, both can secondary injection molding, with the body material coating and bondings such as PP, PE, PC, PS, ABS, also moulding separately.The variation of TPE material, this kind of TPE is organic foam material that a kind of Low Density Polyethylene and several elastomer-bonded form, it is poroid different that this material foams, and is useful in very much footwear industry and ornament.Existing TPE elasticity is not high, and resistance to chemical attack is not strong, easily aging, and preparation process is seriously polluted simultaneously, and people's living environment is impacted.
Low Density Polyethylene (LDPE) is a kind of plastic material, and it is applicable to the various moulding processs of thermoplastic molding's processing, and forming process is good.LDPE main application is to make film product, also for injection-molded item, and medical apparatus, medicine and packaging material for food, blowing slush molding goods etc.
EVA plastic material is ethylene-vinyl acetate copolymer, and the content of the vinyl acetate between to for plastic in EVA lower than 20% time, at this moment just can be used as plastics and uses.EVA (PA66) has good resistance to low temperature, its heat decomposition temperature is lower, is about 230 ℃ of left and right, along with the increase of molecular weight, the softening temperature of EVA rises, processibility and plastic surface luster property decline, but strength increase, impelling strength and environmental stress crack resistance improve, the chemical-resistant resistance of EVA, oil-proofness aspect are than PE, PVC is slightly poor, and with the increase of vinyl acetate content, changes more obvious.The topmost Application Areas of Xie Caishi China EVA resin.In the EVA resin using at footwear material, vinyl acetate content is generally 15%～22%.Because EVA resin alloy foaming product has the performances such as softness, good springiness, resistance to chemical attack, be therefore widely used in the sole and interior material of medium-to-high grade sneakers, climbing boot, slippers, sandals.In addition, this material is also for insulating board, mat and sealing material field.
Polyolefin elastomer (Polyolefin elastomer) (POE) be U.S. DOW chemical company take that metallocene is catalyzer there is narrow molecular weight distribution and short-chain branch distributes uniformly thermoplastic elastomer.This elastomeric salient features is very outstanding, in very many-sided performance index, has surpassed ball gonosome.POE molecular structure is similar to terpolymer EP rubber (EPDM), therefore POE also can have the excellent properties such as ageing-resistant, resistance to ozone, resistant to chemical media, by POE is cross-linked, the heat resisting temperature of material is enhanced, tension set reduces, and the Main Mechanicals such as tensile strength, tear strength all have significant improvement.Multiduty POE elastomerics can surpass PVC, EVA, SBR, EMA and EPDM, and POE may replace traditional EPDM from now on.Because the excellent properties of POE is all applied widely it in the aspects such as automobile industry, electric wire and cable jacket, plastics toughening agent.
