Background technique
Sealing strip be it is a kind of can play damping, waterproof, sound insulation, it is heat-insulated, dust-proof, fixed the effects of product, it is common
Material includes rubber, paper, metal, plastics etc..The incompressible morphotropism of PVC sealing strip, ageing-resistant performance, ozone resistance and resistance to
Chemicals can be good, and processing performance is good, excellent insulation performance, manufacturing cost is low, recycling can be recycled, in car door
The fields such as window, curtain wall are widely used.
Currently, it is mainly solvent-type acrylic pressure sensitive adhesive that PVC sealing strip, which bonds used adhesive, containing more
Volatile materials easily leads to after not only solidifying and occurs bubble in glue film, but also pollutes the environment and cause one to operator
Fixed harm.Hot melt adhesive is solvent-free solid, is free of volatile materials, and easy to use, can be conducive to factory with repetitive operation
Extensive sharp work is all expected to replace solvent-type acrylic pressure sensitive adhesive in many fields.However, existing hot melt adhesive is most
The bonding of PVC sealing strip can not be all carried out, the reason is as follows that: since the heat resistance of PVC itself is poor, so general in PVC sealing strip
All over the plasticizer for being added with high level, to improve its heat resistance, toughness, ductility etc., existing hot melt adhesive is for bonding
When PVC sealing strip, the plasticizer in PVC sealing strip can be migrated into hot melt adhesive, so that the molecular structure of hot melt adhesive becomes loose,
Leading to the softening temperature of hot melt adhesive reduces, and glue film softens, and then loses adhesive property.
