There are many types of automotive interior materials, different properties, and different applications. Therefore, the types of glue used are different from each other, and it is difficult to generalize.
There are many types of automotive interior materials, different properties, and different applications. Therefore, the types of glue used are different from each other, and it is difficult to generalize. Now we will introduce some of the important varieties:
(1) Body roof glue
It is used to paste the soft roof material to the roof of the car body to increase the beauty of the car interior. At present, most of the domestic adhesives for this purpose are solvent-based neoprene, which requires high initial adhesion in terms of process and performance, which meets the fast-paced needs of the car body interior production line, and must not cause the interior materials to change color or fall off.
(2) Butyl sealing tape
It is made of butyl rubber added with tackifying resin and extruded into a tape shape. It is characterized by easy finger pressure bonding, good adhesion to steel plates and waterproof membranes, and long-term viscoelasticity and airtightness. Mainly used for bonding and sealing the waterproof membrane of the inner panel of the car door to prevent rainwater from penetrating into the car door. The amount of tape for a single door on a car is about 2m.
(3) High frequency hot glue
The high-frequency heat-bonding glue for vehicles is a modified acrylic emulsion. When forming the door inner guard plate, the pre-dipped fiberboard (about 30g) is under the action of the high-frequency electric field, the glue layer melts in a short time, and the process is specified Under high pressure, it can bond with PVC foam firmly.
(4) Windshield glue
This type of adhesive is usually based on polyurethane, and is used together with cleaning agents and paint/glass primers. It has high shear strength and outstanding elasticity. It can tightly integrate the glass and the car body into a whole, enhance the rigidity of the car body, and ensure the sealing effect. , Improve car safety. Take the Fukang car as an example, the bicycle consumption is about 1.2kg.
