Embodiment 1

[0037] Refer to attached figure 1 , a kind of automobile EPDM glass run channel sealing strip flocking tape online thermal bonding process of the present embodiment, vulcanize or solidify the produced EPDM sealing strip and carry out flocking tape thermal bonding, utilize vulcanized or cured EPDM sealing strip The built-in temperature heat-melts the flocking tape, which not only utilizes the waste heat that is beneficial to environmental protection and energy saving, but also realizes the online lamination during the production process of EPDM sealing strips, which reduces the cumbersome process of subsequent flocking and saves process, reducing costs. At the same time, compared with the EPDM sealing strip produced by the traditional electrostatic flocking, the EPDM sealing strip produced by the thermal lamination process has better flocking effect and more fluff coverage. Even, during use, the possibility of increased friction with the glass due to uneven flocking is reduced...

Abstract

The invention discloses an online hot laminating process of a flocking belt of a vehicle EPDM glass guide groove sealing strip, and belongs to the technical field of EPDM sealing strip flocking. Hot laminating of the flocking belt is performed after vulcanizing or curing is performed on the produced EPDM sealing strip, and hot-melting laminating is performed on the flocking belt through the temperature of the vulcanized or cured EPDM sealing strip, so that the waste heat utilization beneficial for environment protection and energy conservation is performed, the online laminating in the production process of the EPDM sealing strip is realized, the complicated process of subsequent flocking is reduced, the technological process is saved, and cost is reduced. Meanwhile, compared with a traditional EPDM sealing strip produced through electrostatic flocking, the EPDM sealing strip produced through the hot laminating process has a better flocking effect and is more evenly covered with flocks, the probability that the friction force with glass becomes larger due to the uneven flocking is reduced in the use process, and the noise in the lifting process of vehicle glass is reduced.

Description

technical field [0001] The invention belongs to the technical field of flocking of automobile sealing strips, and specifically relates to an on-line thermal bonding process of flocking tapes of sealing strips of automobile EPDM glass run grooves. Background technique [0002] The current sealing strip is made of EPDM material, and the Chinese name is EPDM rubber. EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated dienes. The most important feature of EPDM is its superior oxidation resistance, ozone resistance and corrosion resistance. Since EPDM belongs to the polyolefin (PO) family, it has excellent vulcanization characteristics. Among all rubbers, EPDM has the lowest specific gravity and can absorb a large amount of fillers and oils with little effect on properties, so that low-cost rubber compounds can be made. [0003] The main polymer chain of EPDM is fully saturated, which makes EPDM resistant to heat, light, oxygen, especially ozone. EPDM is non...
