Description
Technical field
The present invention relates to one material modified, relate in particular to a kind of novel thermoplastic elastomer (TPE) castor material.
Background technology
Industrial castor material mostly in the market is the materials such as polyvinyl chloride (PVC), polyethylene (PP), polyurethane (TPU), as everyone knows, polyvinyl chloride (PVC) manufacturing procedure complexity, lower temperature resistance and resistance to ag(e)ing are poor, especially aspect smell and environmental protection, be subject to larger restriction, various application are fewer and feweri, and even more country bans use of; Polypropylene (PP) source is wider, and processing is simple, environmental-protecting performance excellence, but its hardness range is narrower, and hardness is high, and resistance to low temperature and elasticity are poor, aspect anti-skidding shockproof and elasticity, are being difficult to reach castor materials demand; Polyurethane (TPU) wearability is good, but compared with facile hydrolysis, poor flexibility, resistance to ag(e)ing is poor, and proportion is high, and usability is also restricted.
Summary of the invention
In recent years, the fragmentary castor modification material occurring with phenylethylene elastomer (SBS/SEBS) modification on market, but it does not all obtain compared with quantum jump at aspects such as elasticity, the wear-resisting tests of loading. Like product in the market has following shortcoming:
1. polyvinyl chloride (PVC): proportion is high, manufacturing procedure is complicated, and lower temperature resistance and durability are poor, environmental protection restriction;
2. polypropylene (PP): hardness range is narrow, and hardness is high, poor, the anti-skidding shock resistance of resistance to low temperature and elasticity is poor;
3. polyurethane (TPU): facile hydrolysis, poor flexibility, resistance to ag(e)ing is poor, and hardness range is narrow, and proportion is high.
The technical barrier existing for solving above castor material, a kind of novel thermoplastic elastomer (TPE) castor material in this scheme of the invention, to meeting, market castor material is simple for light weight, processing, environmental protection, high resiliency, high abrasion, lower temperature resistance is good, hardness is moderate etc. performance requirement.
Summary of the invention
The object of the invention realizes and being completed by following technical scheme: a kind of novel thermoplastic elastomer castor material, made by the component of following weight percent:

6) granulation.
This novel thermoplastic elastomer castor material newly developed is taking phenylethylene elastomer SEBS as main body, in addition form with different proportioning physical blendings with a small amount of plastics, processing oil, processing aid etc., wherein SEBS is high-performance styrene analog thermoplastic elastomer, the block copolymer that its structure is made up of the diene block of polystyrene block and hydrogenation, two ends are that polystyrene block, the interlude of rigidity is the soft saturated polyolefin block physical crosslinking of diene structure, before processing, styrene block is as the fixing diene block of crosslinking points. Under the effects such as heating and shearing, styrene block can also can flow in deliquescing. After cooling, styrene block can, again as crosslinking points, retighten diene block again. This physical phenomenon, makes it have good intensity, makes material have to be similar to the elasticity of rubber simultaneously. SEBS is wider from other material available hardness range under different proportionings, and makes it under different hardness condition, have different performances.
Compared with traditional castor material, I take charge of the novel thermoplastic elastomer castor material of exploitation, material novelty, excellent performance, there is the excellent performances such as lower temperature resistance that high-elastic, high abrasion, anti-slip shock absorption, recoverable, manufacturing procedure are simple, nontoxic, good and heat-resistant aging, hardness range are wide, light weight, there is good prospect.
