Description
Technical field：
The invention belongs to plastic formula technical field, specifically, more particularly to a kind of TPE plastics and preparation method thereof.
Background technology：
With developing rapidly for economy, the continuous improvement of enhancing and product requirement of the mankind to environmental consciousness, people are to height
It is required that plastics demand it is increasing.And TPE (Thermoplastic Elastomer, thermoplastic elastomer (TPE)) is that one kind has
High resiliency, high intensity, the high resilience of rubber, again have can injection molding biomaterials, there is asepsis environment-protecting, have excellent
Coloring, weatherability and temperature tolerance, processing characteristics is superior, can recycle, and TPE had both had the processability of thermoplastic
Can, there is the physical property of vulcanization rubber again, be plastics and the advantageous combination of rubber advantage, therefore capture original without restraint
Originally it is pertaining only to vulcanize the manor of rubber.But the price of the TPE is still higher, yield rate is relatively low, need to improve, and wearability and
Heat resistance is not also high.
The content of the invention：
In order to solve the shortcomings that low TPE prices height, yield rate in the prior art, wearability and poor heat resistance, the present invention carries
A kind of TPE plastics for being different from prior art and preparation method thereof are supplied, it is installed, simple and efficient to handle, its cheap, property
Can excellent, high yield rate, environmental protection, antistatic, and there is stronger wearability and preferable heat resistance.
To achieve these goals, the present invention is realized using following technical scheme：
A kind of TPE plastics, it includes the composition of following parts by weight：SEBS23-35 parts, SBS10-25 parts, elastomer 3-12
It is part, TPU30-45 parts, rubber oil 20-30 parts, polypropylene 10-25 parts, zinc stearate 0.4-0.8 parts, coarse whiting 20-30 parts, wear-resisting
Agent 2.2-3.0 parts, heat-resistant agent 1.5-2.3 parts.
Further, the rubber oil proportion is less than TPU proportions.
Further, the SEBS proportions are more than rubber oil proportion.
Further, first SEBS, SBS, TPU and polypropylene are put into mixer, are filled with rubber oil stirring, treat fully to inhale
Elastomer, zinc stearate, coarse whiting, anti-wear agent and heat-resistant agent are added in mixer after oil and stirred, then is added mixture into
Double screw extruder extruding pelletization.
Further, its hardness is 45HB.
Further, its extrusion temperature is 155 °.
Compared with prior art, the beneficial effects of the invention are as follows：
TPE plastics obtained by the present invention are cheap, function admirable, high yield rate, environmental protection, antistatic, and with compared with
Strong wearability and preferable heat resistance.
