Description
Technical field
The present invention relates to sealing strip material field, in particular it relates to a kind of thermoplastic elastomer (TPE) low-density extrusion foaming is close
Seal material and its manufacture method.
Background technology
Sealing strip material in the market mostly is the materials such as polrvinyl chloride (PVC), vulcanite, TPV：
However, polrvinyl chloride (PVC) manufacturing procedure is complicated, lower temperature resistance and resistance to ag(e)ing are poor, and under low temperature, feel is stiff,
Sealing strip sealing effectiveness, PVC density is affected to be generally 1.15-1.20g/cm3, density is higher, in-convenience in use, especially in abnormal smells from the patient
And environmental protection aspect is subject to larger restriction, at relatively high temperatures, such as 50 DEG C or so will decomposite chlorine to polrvinyl chloride (PVC) at leisure
Change hydrogen, foul smelling in the course of processing, this gas are harmful, easily pollute environment.
And as polrvinyl chloride (PVC) requires that matter is soft, add substantial amounts of plasticizer in formula, it is plastic except part
Agent has outside carcinogenic doubt, and these plasticizers slowly can be disengaged to surface over time, therefore for sealing strip in use
Inconvenience and or even to health endangered.Additionally, the heavy metal classes tranquilizer added in the course of processing, if uncontrollable
In the content for requiring, even more health is damaged.Therefore using fewer and feweri or even more multinational on sealing strip material
Family prohibits the use of.
Traditional vulcanite manufacturing procedure is complicated, and basic working procedure includes plasticating, knead, roll or extrude, molding and sulfur
Change etc., high labor intensive, plant equipment are numerous and diverse, due to add white carbon black, accelerator, compounding ingredient and the framework material such as antiaging agent
Deng material, vulcanite belongs to the industry of heavy contamination.
And vulcanite proportion 1.10-1.20g/cm3, proportion is higher, the inadequate lightweight of product.Abnormal smells from the patient is heavier, wherein wrapping
The gas of the generations such as the not altogether clear refining glue of toxicity, sulfuration, plasticizing is included, has different degrees of injury to human body.
TPV thermoplastic dynamic perdurens, as TPV is through sulfidation, so TPV has certain abnormal smells from the patient, it is impossible to full
