1. Bonding of PVC roof and insulation layer, etc.

Most of the bonding of PVC roofing uses solvent-based adhesive, which is used in large quantities. But the use of this adhesive need to ventilate the solvent blow-drying, poor operating conditions, and very environmentally friendly, affecting the health of workers. Therefore, this year and the use of polyamide Hot Melt Adhesive to replace the above adhesive, in addition, the car roof and other heat insulation of the body, but also according to the following sequence of hot pressing and become (hot pressing temperature of 150 ℃). 1. water-resistant corrugated material 2. polyamide hot melt adhesive 3. polyurethane foam 4. polyurethane adhesive 5. polyvinyl chloride plate

Another type of polypropylene honeycomb insulating partition manufactured by vacuum forming, with the following sequence of construction: 1. polypropylene honeycomb core 2. polyamide hot melt adhesive 3. polypropylene film 4. polyurethane adhesive 5. polyvinyl chloride sheet. After the bonding is completed, it can then be formed into a shell with appropriate curvature by vacuum forming method, as the roof or other parts of the body of the car body parts.

2, the bonding of automotive interior decorations

There are many types of automotive interior decorations, in terms of material, most of them belong to PVC or ABS film, sheet, plate, foam plastic sheet, carpet and wood grain decorative panels and other non-metallic materials. The force of the larger decorative panels generally use epoxy resin and other adhesives, while the force of the smaller decorative panels are generally used hot melt adhesive, acrylate emulsion adhesive or solvent-based adhesives, such as plastic sheet wrapped door edges and decorative liner edge, hot melt adhesive can be used to make the edge of the roll to make its position.

Car roof lines, sound-deadening gaskets and rubber windbreaks generally use neoprene or SBR solvent adhesive fixed in the car or door slots; carpets and floors are generally used PA class hot melt adhesive paste.

3, the car body covering parts of the welding seal

In the sealing of the body, the whole car has been in the late stage of the device, therefore, the construction quality requirements are higher, especially some parts of the body outside, the requirements of the adhesive seam as small as possible and smooth, in order to keep the body beautiful. In order to ensure the construction quality and sealing, generally use two-component rubber adhesive, so that the glue has a high initial bonding strength and faster loss of adhesion speed. However, due to the two-component in the construction of temporary preparation, more trouble, can be replaced by hot melt adhesive. Hot melt adhesive is usually applied by a pressure gun with a heating device.

In addition to the above hot melt adhesive, there are also some accessories, such as batteries, sun visors and so on.
