Abstract
The invention discloses a TPE (thermoplastic elastomer) plastic formula and a preparation method thereof. The plastic comprises the following components in parts by weight: 5-15 parts of SEBS (styrene ethylene butylene styrene), 5-20 parts of SBS (styrene butadiene styrene), 10-20 parts of rubber oil, 50-70 parts of TPU (thermoplastic polyurethane), 5-10 parts of 1901 elastomer and 0.1-0.5 part of zinc stearate. A 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 and method thereof.
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: SEBS5-15 part, SBS5-20 part, rubber oil 10-20 part, TPU50-70 part, elastomerics 5-10 part, Zinic stearas 0.1-0.5 part.
Described SBS proportion higher than SEBS proportion, and lower than rubber oil proportion.
Another technical scheme of the present invention is: a kind of preparation method adopting above-mentioned TPE plastic formula, SEBS, SBS, elastomerics are first put into stirrer by it, be filled with rubber oil to stir, Zinic stearas and TPU is added after abundant oil suction, and TPU must dry at least 1 hour before adding stirrer in dryer, then compound is added twin screw extruder extruding pelletization.
Its extrusion temperature is 180 °.
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: SEBS5-15 part, SBS5-20 part, rubber oil 10-20 part, TPU50-70 part, elastomerics 5-10 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.
Zinic stearas has good lubrication.
Elastomerics, for increasing elasticity, is preferably 1901 elastomericss.
Preferably, 10 kilograms of SEBS, 12 kilograms of SBS, 3 kilograms of elastomericss are first put into stirrer by the present invention, be filled with 15 kilograms of rubber oils to stir, 0.3 kilogram of Zinic stearas and 60 kilograms of TPU are added and TPU must dry 1 hours before adding stirrer in dryer after abundant oil suction, again compound is added twin screw extruder extruding pelletization, extrusion temperature is about 180 °.Product made by this formula after testing after and ABS have good binding property and transparent, proportion is lighter.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.
