Abstract
The invention discloses a formula of ultraviolet-resistant TPE (Thermoplastic Elastomer) plastics. The formula contains the following ingredients in parts by weight: 15-25 parts of SEBS, 1-10 parts of SBS, 30-40 parts of white oil, 0.1-2 parts of anti-ultraviolet agent, 0.1-2 parts of antioxidant, 10-25 parts of calcium carbonate, 10-25 parts of PP and 0.1-1 part of zinc stearate. The TPE plastics prepared by adopting the formula are cheap, environment-friendly and ultraviolet-resistant, are high in yield and excellent in properties and meet different requirements of customers.
Description
Technical field
The present invention relates to a kind of uvioresistant 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 uvioresistant TPE plastic formula of environmental protection.
A technical scheme of the present invention is: a kind of uvioresistant TPE plastic formula, and it comprises the composition of following weight part: SEBS 15-25 part, SBS 1-10 part, white oil 30-40 part, anti UV agent 0.1-2 part, antioxidant 0.1-2 part, calcium carbonate 10-25 part, PP 10-25 part, Zinic stearas 0.1-1 part.
Described SEBS proportion and calcium carbonate, PP proportion are all identical.
Described anti UV agent proportion is identical with antioxidant proportion, and is greater than Zinic stearas proportion.
Another technical scheme of the present invention is: a kind of preparation method adopting described uvioresistant TPE plastic formula, SEBS, SBS are first put into stirrer by it, be filled with white oil to stir, after abundant oil suction, add anti UV agent, antioxidant, calcium carbonate, Zinic stearas and PP enter stirring, compound is added twin screw extruder extruding pelletization.
Advantage of the present invention is:
TPE plastics low price obtained by the present invention, yield rate are high, excellent property, environmental protection, uvioresistant.
Embodiment
Embodiment: the specific embodiment that the invention provides a kind of uvioresistant TPE plastic formula, it comprises the composition of following weight part: SEBS 15-25 part, SBS 1-10 part, white oil 30-40 part, anti UV agent 0.1-2 part, antioxidant 0.1-2 part, calcium carbonate 10-25 part, PP 10-25 part, Zinic stearas 0.1-1 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, there is satisfactory stability and ageing resistance.
SBS (styrene-butadiene-styrene) has good tensile strength, and skin friction coefficient is large, low-temperature performance good, good processability.
PP has higher shock-resistance, mechanicalness and obdurability, anti-multiple organic solvent and acid and alkali corrosion, can the soft durometer of control TPE.
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.
Antioxidant has the effect delaying the aging of product, and anti UV agent can delay and suppress ultraviolet to cause the material of photoaging to polymkeric substance.
Zinic stearas has good lubrication.
Preferably, 20 kilograms of SEBS, 5 kilograms of SBS are first put into stirrer by the present invention, be filled with 35 kilograms of white oils to stir, after abundant oil suction, add 0.6 kilogram of anti UV agent, 0.6 kilogram of antioxidant, 20 kilograms of calcium carbonate, 0.5 kilogram of Zinic stearas and 20 kilograms of PP stir, compound is added twin screw extruder extruding pelletization.Product made by this formula after testing after and PP have good binding property, and be attached on polypropylene and cannot directly remove with hand, and there is 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.
