Abstract
The invention discloses a TPE (thermoplastic elastomer) plastic formula. The formula comprises the following components in parts by weight: 26-35 parts of SEBS (styrene ethylene butylene styrene), 3-10 parts of SBS (styrene butadiene styrene), 34-43 parts of rubber oil, 12-18 parts of PP (polypropylene), 3-10 parts of heavy calcium carbonate and 0.1-0.4 part of zinc stearate. The TPE plastic prepared by adopting the formula 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 plastic formula.
Background technology
Along with developing rapidly of economy, the mankind must improve constantly the enhancing of environmental consciousness and product requirement, and people are increasing to the plastics demand of high request.And TPE (Thermoplastic Elastomer thermoplastic elastomer) is a kind of snappiness with rubber, high strength, high resilience, have again can injection molding feature material, there is asepsis environment-protecting, there is good 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 moulding separately, TPE had both had the processing characteristics of thermoplastics, the physicals again with vulcanized rubber, it is the advantage combination of plastics and rubber advantage, therefore without restraint capturing the manor that only belongs to vulcanized rubber originally.Yet the price of this TPE is still higher, and yield rate is lower, be 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 that client is different to be required and the TPE plastic formula of environmental protection.
A technical scheme of the present invention is: a kind of TPE plastic formula, it comprises the composition of following weight part: SEBS 26-35 part, SBS 3-10 part, rubber oil 34-43 part, PP 12-18 part, coarse whiting 3-10 part, Zinic stearas 0.1-0.4 part.
Described SEBS proportion is higher than rubber oil proportion, and SBS is identical with the ratio of coarse whiting.
Another technical scheme of the present invention is: a kind of employing is the preparation method of TPE plastic formula as claimed in claim 1, it first puts into stirrer by SEBS, SBS, being filled with rubber oil stirs, add Zinic stearas, PP and coarse whiting after abundant oil suction after, stir, then compound is added to twin screw extruder extruding pelletization.
Its extrusion temperature is 150 °.
Advantage of the present invention is:
The prepared TPE plastics of the present invention low price, yield rate are high, excellent property, environmental protection, anti-electrostatic.
Embodiment
Embodiment: the invention provides a kind of specific embodiment of TPE plastic formula, it comprises the composition of following weight part: SEBS 26-35 part, SBS 3-10 part, rubber oil 34-43 part, PP 12-18 part, coarse whiting 3-10 part, Zinic stearas 0.1-0.4 part.
SEBS be take polystyrene as end segment, the polyhutadiene hydrogenation of take obtains ethylene-butene copolymer as the linearity three embedding multipolymers of middle elastomeric block, claim again 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.
SBS (styrene-butadiene-styrene) has good tensile strength, and skin friction coefficient is large, low-temperature performance good, good processability.
Rubber oil is for improving the characteristics such as elasticity, snappiness, workability, easy mixing property of rubber.
PP (polypropylene) has higher shock-resistance, and mechanicalness and obdurability resist multiple organic solvent and acid and alkali corrosion, can control the soft durometer of TPE.
First adding of coarse whiting be for as weighting material, moreover for improving hardness and the proportion of product.
Zinic stearas has good lubrication.
Preferably, the present invention first puts into stirrer by 40 kilograms of SEBS, 10 kilograms of SBS, being filled with 50 kilograms of rubber oils stirs, add 0.3 kilogram of Zinic stearas, 20 kilograms of PP and 10 kilograms of coarse whitings after abundant oil suction after, stir, compound is added to twin screw extruder extruding pelletization, and extrusion temperature is 150 ° of left and right.The product of this formula made has good binding property with PP after after testing, and is attached to PP and goes up and cannot directly remove with hand.The invention has the beneficial effects as follows: low price, yield rate are high, excellent property.
Certainly above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformation or modification that according to the present invention, the spirit of main technical schemes is done, within all should being encompassed in protection scope of the present invention.
