Abstract
The invention discloses a TPE (thermoplastic elastomer) plastic formula. The formula comprises the following components in parts by weight: 10-20 parts of SEBS (styrene ethylene butylene styrene), 5-20 parts of SBS (styrene butadiene styrene), 1-10 parts of elastomer, 20-40 parts of TPU (thermoplastic polyurethanes), 10-25 parts of polypropylene, 10-30 parts of rubber oil and 0.1-0.5 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 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 plastic formula of environmental protection.
A technical scheme of the present invention is: a kind of TPE plastic formula, and it comprises the composition of following weight part: SEBS 10-20 part, SBS 5-20 part, elastomerics 1-10 part, TPU 20-40 part, polypropylene 10-25 part, rubber oil 10-30 part, Zinic stearas 0.1-0.5 part.
Described SEBS proportion is less than rubber oil proportion, and rubber oil proportion is lower than the proportion of TPU.
Another technical scheme of the present invention is: a kind of preparation method adopting described TPE plastic formula, SEBS, SBS are first put into stirrer by it, be filled with rubber oil to stir, add after abundant oil suction after must drying 1 hour in dryer before elastomerics, Zinic stearas, polypropylene and TPU add stirrer and stir, then compound is added twin screw extruder extruding pelletization.
Its hardness is 60 °.
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 plastic formula, it comprises the composition of following weight part: SEBS 10-20 part, SBS 5-20 part, elastomerics 1-10 part, TPU 20-40 part, polypropylene 10-25 part, rubber oil 10-30 part, Zinic stearas 0.1-0.5 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.
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 characteristic such as elasticity, snappiness, workability, easy mixing property of rubber.
Polypropylene has higher shock-resistance, mechanicalness and obdurability, anti-multiple organic solvent and acid and alkali corrosion, can the soft durometer of control TPE.
TPU (Thermoplastic Polyurethanes) name is called Polyurethane Thermoplastic Elastomer rubber, has consistency, adds elastomerics and makes binding property better.
Zinic stearas has good lubrication.
Preferably, 15 kilograms of SEBS, 10 kilograms of SBS are first put into stirrer by the present invention, be filled with 20 kilograms of rubber oils to stir, after abundant oil suction, add 5 kilograms of elastomericss, 30 kilograms of TPU, 20 kilograms of polypropylene, 0.3 kilogram of Zinic stearas must be dried 1 hours before adding stirrer and be stirred in dryer, compound is added twin screw extruder extruding pelletization.Product made by this formula after testing after and ABS have good binding property, and be attached on polypropylene and cannot directly remove with hand, and have high wear resistance, hardness is at about 60 °.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.
