What adhesive for automotive interior decoration is used for automotive interior parts
Types of adhesive for automotive interior decoration:
(1) The body roof glue is used to paste the soft roof material to the body roof to increase the beauty of the car.
At present, the adhesive for automotive interior decoration for this purpose in China is mainly based on solvent-based neoprene, which requires high initial adhesion in terms of technology and performance, meets the fast-paced needs of the body interior production line, and does not cause discoloration of interior materials. , falling off phenomenon.
(2) Butyl sealing tape It is made of butyl rubber with tackifying resin and extruded into a tape shape. tightness. It is mainly used for the sealing of the waterproof membrane of the inner panel of the door to prevent rainwater from infiltrating the interior of the door.
(3) High-frequency heat-sealing glue Fukang and other cars use high-frequency heat-sealing glue as a modified acrylic solution. When forming the inner door panel, the fiberboard that has been pre-dipped (about 30g) is under the action of high-frequency electric field. The adhesive layer melts in a short time and creates a firm bond with the PVC foam under the force specified by the process.
(4) Windshield adhesive This type of adhesive is usually based on polyurethane. It is used together with cleaning agent and paint/glass primer. It has high shear strength and outstanding elasticity, and can closely combine the glass and the body into one Overall, the rigidity of the body is enhanced, the sealing effect is ensured, and the safety of the vehicle is improved.
Since the early 1970s, car interior decoration began to use non-metallic materials such as plastic foam and fabric that can absorb impact energy and reduce impact to manufacture door armrests, backrests, pillow pads, seat cushions, ceilings, dashboards, steering wheels, etc. Artificial leather, fiberboard, felt, plastic film, etc. are also commonly used materials in interior parts. The combination and assembly of these materials require different adhesive for automotive interior decoration.
MODIFIED ACRYLIC AB ADHESIVE (BOXES) uses methyl methacrylate as the main raw material, with tougheners, reinforcing agents, stabilizers, initiators, polymerization inhibitors, etc., two components synthesized through advanced technology (A, B) Reactive structural adhesive.
