Description
Technical field
The present invention relates to technical field of polymer materials, and in particular to a kind of thermoplastic elastic body sealing strip material.
Background technique
It is increasing to the demand of sealing strip with the rapid development of the household electric appliances, automobile industry in China, it is desirable that
Higher and higher, China has become automobile, consumption appliance big country, therefore sealing strip has a vast market and prospect.
With the development of industry, novel sealing strip material is more and more, and wherein thermoplastic elastic material is exactly most prominent
One of environment-friendly materials out, it is broadly divided into polyolefins（TPO,TPV）, polyurethanes（TPU）, polyvinyl chloride
(PVC), phenylethylene（TPE）Etc. types thermoplastic elastomer (TPE).
Thermoplastic elastomer (TPE) (thermoplastic elastomer, abbreviation TPE), which refers at normal temperature, has vulcanization rubber
The property of glue（That is the property of elastomer）, can be plastically deformed again at high temperature, since it is to be heated to have plastic bullet
Property body, Gu be known as hot elastico-plastic body.TPE is made of rubber phase constituent and plastics phase constituent.
It vulcanized rubber complex process and is difficult to recycle and utilizes again, than the silicon rubber of writer's electricity sealing strip material as usual, though
So it has excellent performance, but complex process, production efficiency is low, and material cost is expensive.And polyvinyl chloride contains halogen and containing big
Therefore the plasticizer of amount has certain negative effect to environment, as people increasingly pay attention to environmental requirement, novel environment friendly material
The use of material becomes following development trend, and TPE is to have both the feature of environmental protection simultaneously, not only with the property of thermoplastic, but also
Property with vulcanized rubber, it is not necessary to add sulphur operation, the processing is simple, and it is reusable, therefore thermoplastic elastomer (TPE) (TPE) is close
The industry of strip of paper used for sealing can play the part of more and more important role.
However, performance of the conventional thermoplastic elastic material TPE in terms of heat resisting and the equal solvent of resistance to vegetable oil
There is obvious shortcoming, is also insufficient for the requirement that Seal tape for tableware washing machine washs resistance to vegetable oil and high temperature resistant.
