Abstract
The invention discloses a TPE (thermoplastic elastomer) plastic. The plastic comprises the following components in parts by weight: 15-25 parts of SEBS (styrene ethylene butylene styrene), 15-25 parts of EPDM (ethylene propylene diene monomer), 5-15 parts of elastomer, 1-10 parts of PA (polyamide) 66, 10-20 parts of TPV (thermoplastic vulcanizate) and 20-35 parts of white oil. The prepared TPE plastic is cheap, has high yield and excellent performances, meets different requirements of customers and is environment-friendly.
Description
Technical field
The present invention relates to a kind of TPE plastics.
Background technology
Along with developing rapidly of economy, the mankind must improve constantly the enhancing of environmental consciousness and product requirement, and the plastics demand of people to high request is increasing.And TPE (Thermoplastic Elastomer thermoplastic elastomer) is a kind of snappiness with rubber, high strength, high resilience, having again can the biomaterials of injection molding, there is asepsis environment-protecting, there is excellent tint permanence, weathering resistance and temperature tolerance, processing characteristics is superior, can recycle, with PP, PC, PS, the body material coating and bondings such as ABS, also can be shaping separately, TPE had both had the processing characteristics of thermoplastics, there is again the physicals of vulcanized rubber, it is the advantageous combination of plastics and rubber advantage, therefore the manor originally only belonging to vulcanized rubber is without restraint being captured.But the price of this TPE is still higher, yield rate is lower, is badly in need of improving.
Summary of the invention
The present invention seeks to: provide that a kind of low price, yield rate are high, excellent property, meet client's difference and require and the TPE plastics of environmental protection.
A technical scheme of the present invention is: a kind of TPE plastics, and it comprises the composition of following weight part: SEBS 15-25 part, EPDM 15-25 part, elastomerics 1-15 part, PA661-10 part, TPV 10-20 part, white oil 20-35 part.
Described SEBS proportion is lower than white oil proportion, and identical with the ratio of EPDM, and TPV proportion is higher than elastomerics proportion simultaneously.
Another technical scheme of the present invention is: a kind of preparation method adopting described TPE plastics, SEBS, EPDM are first put into stirrer by it, be filled with white oil to stir, after abundant oil suction, add PA66, TPV and elastomerics add stirrer and stir, then compound is added twin screw extruder extruding pelletization.
Its hardness is 65 °.
Advantage of the present invention is:
TPE plastics low price obtained by the present invention, yield rate are high, excellent property, environmental protection, anti-electrostatic.
Embodiment
Embodiment: the specific embodiment that the invention provides a kind of TPE plastics, it comprises the composition of following weight part: SEBS 15-25 part, EPDM 15-25 part, elastomerics 5-15 part, PA661-10 part, TPV 10-20 part, white oil 20-35 part.
SEBS take polystyrene as end segment, the linear three embedding multipolymers that ethylene-butene copolymer is middle spring block are obtained with polyhutadiene hydrogenation, also known as styrene-ethylene-butylene-styrene block copolymer, not containing unsaturated double-bond, have satisfactory stability and ageing resistance, the present invention uses polymer SEBS to have good pulling force.
The main characteristic of EPDM is its superior scale resistance, ozone-resistant and erosion-resistant ability, and it has fabulous vulcanization characteristics, can absorb a large amount of fillers and oil and influencing characteristic is little.
Elastomerics can strengthen binding property, is preferably 1901 elastomericss.
PA66 has excellent wear resistance, self lubricity, and physical strength is higher, also can keep stronger strength and stiffness at relatively high temperatures.
TPV has good elasticity and compression deformability, resistance to environment, and ageing resistance is equivalent to terpolymer EP rubber, and its oil resistant solvent resistance is equally matched with polychloroprene rubber for general purpose simultaneously.
White oil is height refined product, has colourless, tasteless, nontoxic.Calcium carbonate add one be in order to increase binding property another be reduce cost.
Preferably, 20 kilograms of SEBS, 20 kilograms of EPDM are first put into stirrer by the present invention, be filled with 30 kilograms of white oils to stir, after abundant oil suction, add 5 kilograms of PA66,15 kilograms of TPV and 10 kilogram elastomericss add stirrer and stir, then compound is added twin screw extruder extruding pelletization.Product made by this formula after testing rear and nylon has good binding property, and has high wear resistance, and hardness is at about 65 °.The invention has the beneficial effects as follows: low price, yield rate are high, excellent property.
Certain above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the spirit of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
