Description
Technical field
The invention belongs to polymeric material field, it is related to a kind of composite, more particularly to a kind of cold-resistant high resiliency is fire-retardant
TPE composites and preparation method thereof.
Background technology
Thermoplastic elastomer (TPE) TPE is a kind of high resiliency with rubber, high intensity, high resilience, have again can be molded plus
The material of work feature.TPE has environment-protecting and non-poisonous safety, and hardness range is wide, there is an excellent coloring, soft-touch, weatherability,
Fatigue resistance and temperature tolerance, processing characteristics is superior, without vulcanization many advantages, such as, therefore, as a kind of new multi-functional ring
Material is protected, TPE has boundless application market, such as household electrical appliance, sports goods, automotive material, medicine equipment, construction industry
With shoe industry etc..At present, TPE composites are usually and are total to thermoplastic elastomer (TPE) hydrogenated styrene-butadiene-styrene block
Polymers (SEBS), thermoplastic polypropylene and some suitable fillers are what raw material was prepared.SEBS elastomers
Block hydrogenates completely, makes it have excellent weather resistance, has good tolerance to ozone, ultraviolet, electric arc, also makes
It has resistance to low temperature, good pliability is still kept under the conditions of -60 DEG C the features such as.Although SEBS has excellent rubber
Elastic, excellent weatherability, lower temperature resistance, environmental-protecting performance etc., but be individually to use to exist using SEBS as elastomeric material
Problem, if SEBS is compared with traditional vulcanization rubber, there is rigidity it is excessive, compression is big, density is high the shortcomings of；It is used
Temperature upper limit and solvent resistance, oil resistivity etc. are generally all not as good as conventional vulcanized rubbers etc..In addition, PP is cheap, can drop
Low SEBS cost.
The A of CN 105367896 disclose a kind of TPE pulling force materials in the tube and preparation method thereof, the TPE pulling force materials in the tube by including
SEBS, PP, vinylpyridine Maleated SEBS, POE and white oil composition；Its preparation method includes：Raw material is weighed by weight ratio,
First by SEBS, PP, vinylpyridine Maleated SEBS, POE, white oil, fully mixed in high speed mixer, obtain mixture；With
Obtained mixture is put into extruding pelletization in screw extruder afterwards.The TPE pulling force materials in the tube have high resiliency, high intensity, weather-proof
Property is good, suitable for the preparation of body-building apparatus.But invention TPE composites can only be used to sports equipment, at other
The application in field still demonstrate flexibility deficiency the problem of.
