Description
Technical field
The invention belongs to polyurethane elastomer production field more particularly to modified thermoplastic polyurethane elastomer production systems
System.
Background technology
Polyurethane elastomer excellent wear-resisting property, good mechanical property, tear resistance are excellent, this is because polyurethane is hard
There is very strong polar group in section part, and such structure causes polyurethane that can form hydrogen between portion and molecule in the molecule
Key under the action of hydrogen bond, generates physical crosslinking, it is made to have the famous of " abrasive rubber " inside polyurethane.By material plus
The difference of work method, polyurethane elastomer can be divided into following three kinds：Thermoplasticity, casting type and mixed milling type.Wherein thermoplastic poly
Urethane elastomer (TPU) is a kind of novel environment friendly sealing material, and physics, chemical property are excellent, and tool has excellent thermoplasticity,
Wear-resisting, resistant to shearing, chemical-resistant, processing method is various, there is very big flexibility, adjustability, mainly have extrusion molding,
Injection molding is widely applied in sealing member material.The high abrasion resistance of polyurethane material, but due to polyurethane point
Containing extremely strong polar group in son, cause polyurethane surface can it is higher, polyurethane self lubricity is poor, sliding friction occurs
When, the coefficient of kinetic friction is bigger than normal, and antifriction quality is insufficient so that the heat generated during friction increases, this causes polyurethane in friction field
Application receive certain limitation, when being applied in large sealing device, frictional resistance is big, frictional heat is more, easily
Sealing element is caused to wear, especially in the large sealing device to run at high speed, easily sealing element is caused to be extruded, caused the accident.

There is certain practical significance for the application of polyurethane material.
Modified thermoplastic polyurethane elastomer production system is typically the universal thermoplastic poly by controlling material rate
What urethane elastomer, remodeling substance, compatilizer and a variety of auxiliary agent raw material hybrid reactions obtained, in the actual production process, due to
Each raw material components cannot be equably distributed, and soft segment and hard segments arrangement are uneven, so as to cause obtained modified thermoplastic polyurethane
Elastomer product performance is unstable；Meanwhile generate vibration in screw extruder work in process of production and form noise pollution, together
When screw extruder easily there is localized hyperthermia, so as to cause the carbonization of TPU, the finished product produced is made to have flaw, thus production in
It needs to increase filter device, for filtering the impurity generated in production process.In usually used filter device, when strainer pressure difference
When reaching a certain level, illustrate that filter net jam is serious, it is necessary to replace, need first to suspend underwater cutpellet at this time, be connect again after replacing strainer
Production.Strainer is replaced due to needing to stop, raw material is not only wasted, can also cause unstable traditional modification thermoplastic of production
Property polyurethane elastomer production system can not solve problem above.
