Technical field
The present invention relates to a kind of macromolecular material and preparation method thereof, relate to a kind of PVC thermoplastic elastic material and preparation method thereof more specifically.
Background technology
SE (PVC) analog thermoplastic elastomer and polyolefins, polystyrene-type thermoplastic elastomers; On thermoplastic elastomer (TPE) market, occupy very big share together; Because the PVC thermoplastic elastic material has the repetition processibility of thermoplastics and the physical and mechanical propertiess such as snappiness of rubber concurrently; Have simultaneously reclaiming property again, the equivalent material that is used as soft polymer and vulcanized rubber as a kind of brand-new macromolecular material increases rapidly, has formed bigger market scale.
At present, conventional PVC elastomer material kind is more, and the preparation method is different.But on the whole, its prescription all is associated with performance of products.
Summary of the invention
One of purpose of the embodiment of the invention is to provide a kind of elastomeric PVC thermoplastic elastic material.
The present invention is achieved in that
A kind of PVC thermoplastic elastic material comprises the polychloroethylene with high polymerization degree of 100 weight parts, the softening agent of 50 to 80 weight parts, the snappiness properties-correcting agent of 30 to 50 weight parts, the thermo-stabilizer of 4 to 6 weight parts, the lubricant of 0.3 to 0.6 weight part, the processing aid of 1 to 3 weight part, the oxidation inhibitor of 0.2 to 0.5 weight part, the weighting agent of 5 to 10 weight parts.
Scheme further is: the polymerization degree of said polychloroethylene with high polymerization degree is not less than 1300.
Scheme further is: said softening agent is one or more in DOP, adipic acid dioctyl ester, trioctyl phosphate, BS, the epoxy soybean oil.Wherein DOP is a primary plasticizer, other be co-plasticizer.
Scheme further is: said snappiness properties-correcting agent is one or more in paracril, cis-1,4-polybutadiene rubber, styrene-butadiene rubber(SBR), terpolymer EP rubber, the acrylic resin.
Scheme further is: said thermo-stabilizer is a complex lead salt stabilizer.Thermo-stabilizer can improve the auxiliary agent of PVC thermostability, and its effect is the degraded that in the PP Pipe Compound production process, prevents or suppress PVC, in the use of goods, keeps enough thermostabilitys simultaneously, increases the service life; Complex lead salt stabilizer mainly contains the plumbous mixture of organic barium cadmium, the plumbous zinc complexes of phosphorous acid calcium, sublimed lead plumbous sulfite mixture.
Scheme further is: described lubricant is one or more in Triple Pressed Stearic Acid, methylene-bis stearylamide, glyceryl ester, the oxidic polyethylene.Lubricant can guarantee to reduce material melt viscosity, prevent the adhesion of material on processing units or mould.
Scheme further is: described processing aid is an acrylic resin, and this resin can promote the plasticizing of PVC and can guarantee that plasticizing evenly.The commonly used vinyl resin that hydroxyl is arranged, carboxylic vinyl resin, contain epoxy group(ing) vinyl resin, contain amino vinyl resin, amide-containing vinyl resin, contain the vinyl resin of alkoxyl group etc.
Scheme further is: described oxidation inhibitor is phenolic antioxidant, amine antioxidants, phosphite ester kind antioxidant, contain in the thioesters kind antioxidant any one or a few.The effect of oxidation inhibitor is to catch in PVC processing or use because of being heated or receiving the radical that action of ultraviolet ray forms, the life-span that the assurance material uses.
Scheme further is: described weighting agent is one or more in treated carbonates, talcum powder, kaolin, the mica powder.
The used basic resin of snappiness PVC thermoplastic elastic material among the present invention is a polychloroethylene with high polymerization degree; This material is except that the general aspects that possesses PVC RESINS; Also have good caoutchouc elasticity (compression set, elongation tension set, rebound resilience etc.) and physical strength.With other TPE different be, through the adjustment plasticizer dosage, can arbitrarily design hardness Different products (from the high firmness to the soft).Only this a bit just can have widely purposes and approved by market as the snappiness PVC thermoplastic elastic material of TPE product.Through selecting to use different types of softening agent, might obtain oil-proofness, heat-resistant aging, and do not make performances such as softening agent moves in the resin that it contacted.
The present invention also provides the preparation method of said PVC thermoplastic elastic material; Be after prescription with said PVC thermoplastic elastic material prepares, stir and be warming up to 100 ℃, kept 15 minutes with impeller; The back is stirred at low speed mixer and is cooled to 50 ℃; The blowing postcooling plastified 5 minutes under 140 ℃ of temperature with double roller plastic-making device to room temperature, made snappiness PVC thermoplastic elastic material pellet.
The PVC thermoplastic elastic material of the present invention's preparation has following characteristic: rebound resilience is apparently higher than general PVC thermoplastic elastomer; Low compression set; Good heat aging property, winter hardiness, mechanical strength; Good processing characteristics and exterior trim property.Concrete main performance index is following:
