Abstract
The invention discloses a formula of thermoplastic elastomer. The formula comprises the following components in parts by weight: 15-25 parts of SEBS, 15-25 parts of EPDM, 10-25 parts of TPV, 1-10 parts of PA6, 1-10 parts of monomer resin and 20-35 parts of white oil. The thermoplastic elastomer prepared by the formula disclosed by the invention is cheap and environmentally friendly and high in rate of finished products, has excellent performance and is in line with customer requirements.
Description
Technical field
The present invention relates to a kind of thermoplastic elastomer formula.
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 thermoplastic elastomer formula of environmental protection.
A technical scheme of the present invention is: a kind of thermoplastic elastomer formula, and it comprises the composition of following weight part: SEBS 15-25 part, EPDM 15-25 part, TPV 10-25 part, PA6 1-10 part, monomer resin 1-10 part, white oil 20-35 part.
Described SEBS proportion is lower than white oil proportion, and the ratio of SEBS and EPDM, TPV is all identical.
Another technical scheme of the present invention is: a kind of preparation method adopting described thermoplastic elastomer to fill a prescription, SEBS, EPDM are first put into stirrer by it, be filled with white oil to stir, after abundant oil suction, add PA6, TPV and monomer resin add stirrer and stir, then compound is added twin screw extruder extruding pelletization.
Advantage of the present invention is:
Thermoplastic elastomer 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 thermoplastic elastomer formula, it comprises the composition of following weight part: SEBS 15-25 part, EPDM 15-25 part, TPV 10-25 part, PA6 1-10 part, monomer resin 1-10 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.
The chemico-physical properties of PA6 is very similar with PA66, but its fusing point is lower, and Process temperature ranges is very wide, its shock resistance and resist dissolution better than PA66.
Monomer resin has good thermostability, and softening temperature is lower, and being used for increasing force of cohesion in hot melt adhesive system as tackifying resin does not but affect just sticky effect, has good compatibility with most of solvent.
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 8 kilograms of PA6,20 kilograms of TPV and 3 kilogram monomer resins 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.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.
