Description
Technical field
The present invention relates to trolley castors material, it particularly relates to a kind of high-elastic castor material of TPE.
Background technology
Thermoplastic elastomer (TPE) TPE (Thermoplastic Elastomer) is a kind of high resiliency with rubber, high-strength
Degree, high resilience, again have can injection molding feature material.With environment-protecting and non-poisonous safety, have a wide range of application, there is excellent
Coloring, soft-touch, weatherability, fatigue resistance and temperature tolerance, processing characteristics are superior, without vulcanization, can recycle drop
Low cost, both can be with secondary injection molding, and the matrix material coating and bonding such as PP, PE, PC, PS, ABS can also be separately formed.
Apply to hospital, airport, the trolley of megastore bears a heavy burden compared with general trolley greatly, and its castor material is usually
Polyurethane, cast iron and steel, nitrile rubber rubber tire (NBR), NBR etc., in general elasticity is not good for this kind of material, carries out noise
Greatly, abrasion resistance is not high.Therefore, the service life that result in trolley castors is not long, and Experience Degree is not high.
The content of the invention
The technical problem to be solved in the present invention is to provide the high-elastic castor material of a kind of environment-protecting and non-poisonous and wear-resisting TPE.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of high-elastic castor material of TPE, by following weight
The each component composition of number：SEBS:35-45 parts, 25-35 parts of white oil, polypropylene：10-20 parts, 10-20 parts of processing aid.
The preparation method of the above-mentioned high-elastic castor material of TPE, comprises the following steps：
1) mix：The SEBS of above-mentioned parts by weight is added into white oil, polypropylene, processing aid mix 30min, obtained
Mixture A；
2) extrude：Mixture A is passed through into 230 DEG C of extrusions of Couble screw rod high-temp；
3) pelletizing：The pelletizing in water by the material after extrusion；
4) material dewatering drying, the removal of impurities of grain will be cut into；
5) weigh packaging.
Using above-mentioned technical proposal, the present invention is to meet ROHS standards, high resiliency, noiseless, the high shell foots of wear-resisting TPE of walking
Wheel material, made finished product castor loads 250kg, takes turns 4 kilometers/hour of rotor speed, and wheel rotation 15000 encloses wheel surface without abrasion,
Without decortication phenomenon.
