China's auto industry new materials, new technology continues to promote the use of automotive adhesives continue to improve and specialization. It is estimated that by 2010, the total demand of various types of adhesives will reach 100,000 tons in China's automobile industry. Thus, the application of adhesives in vehicle manufacturing is in a very important position, the scope of an application is also constantly expanding, the amount is also increasing. The development and application of new high-quality automotive adhesives will become more and more important with the development of energy-saving, safe, comfortable, lightweight, low-cost, long-life and pollution-free.
(1) light-weight adhesive such as low-density PVC weld sealant, low-density PVC anti-stone hit paint. Ordinary PVC sealing material density of 1.40g / cm3, and low density PVC sealing material density can reach 0.9 ~ 1.Og / cm3, in the same thickness (volume) of the sealing material can reduce the quality of 30% to 35% .
(2) environment-friendly adhesive water-based material has begun to appear and replace the oil to remove bonding, sealing products. Such as the use of water-based sealant to replace the widely used PVC cutting sol, as well as the use of asphalt-based vehicle damping plate. As the water-based materials can be dry or dry-type, damping coefficient than PVC, asphalt materials, high environmental pollution, good prospects for application. In addition, PVC sealant, car anti-stone coating is also in the automotive manufacturing process has been applied.
(3) wet wet type PVC sealing material The so-called wet-wet process that PVC sealing material is not pre-curing (pre-gel) process, and directly in the wet PVC coating surface coating material, PVC material to dry The oven was dried with the coating. This requires PVC material and paint a good adaptability does not appear floral, sagging, shrinkage, pinhole and so does not complete the problem. So that the car plant's painting shop without the need to set up PVC pre-drying furnace, in order to improve production efficiency and energy conservation.
 (4) multi-functional plate reinforcement materials with the requirements of lightweight vehicles, the body of the steel plate thickness is getting thinner, but some parts (such as the door handle hole) require a higher intensity. The application of sheet reinforcement can solve this problem. Commonly used thin-layer reinforced materials mainly composed of epoxy resin modified materials. There are preforms, there are liquid sprayable material. Reinforced materials in the curing process of drying paint, paste on the steel plate, not only play a role in local reinforcement, but also can reduce the vibration of steel plate to eliminate noise. For example, a lightweight, multi-functional reinforcing material having shock resistance and heat insulation properties has been newly developed, which is made of a mixture of a thermosetting epoxy resin and a PVC resin, which is blended with a foaming agent and other additives, and is heavier than the surface material. Between the surface material and non-adhesive paper paste such a layer of reinforced sheet, and then release the electrophoretic coating oven foam, curing. The foam sheet having a thickness of about 1 mm forms a foam sheet of about 6 mm, which serves as a reinforcing and anti-shock effect and exhibits a good balance. The price compared with the original reduced by about 40%, weight reduction of about 60%.
 (5) to meet the requirements of the clean paint shop clean paint shop concept is not directly related with the painting of the construction of the material from the painting shop ahead of the welding shop or moved to the assembly plant to reduce Affect the cleanliness of the coating shop operation, reduce rework, rework, reduce manufacturing costs. The adhesive construction in the welding shop to change the requirements of the development of welding workshop used decorative welding seam sealant. The anti-stone paint coating in the end after moving to the assembly plant construction, requiring the use of materials can be cured at room temperature.
(6) Spray-type vibration-damping sound-absorbing material to replace the asphalt damping plate As the car manufacturing asphalt damping plate used in different shapes, need to take up a lot of storage space, construction waste of manpower, while bringing a lot of dust, affecting the paint shop environment . The use of spray-type vibration and sound insulation materials can be automated by the robot construction, while reducing manufacturing costs. Spray-type vibration insulation materials are PVc plastic sol, water-based acrylic glue.
(7) The new polyurethane glass adhesive The appearance of aluminum body and the application of glass built-in antenna, the use of glass adhesive with high resistance (low rate of arrival), to prevent corrosion caused by the body and the antenna to accept the effect Of the adverse effects. Adhesive corridor foot profile modulus to improve the rigidity of the body, to improve the anti-distortion, to ensure the safety of the crew of the umbrella. New, published polyurethane glass adhesive with low conductivity type, high modulus, high modulus low conductivity type, fast curing type.
 (8) Approximate curing type semicircular structure adhesive Original semi-circular structure such as roof cover or door is used as anti-rust purpose solution-type heat curing epoxy resin adhesive. To improve the rust resistance of the semicircular structural part by one step, it is desirable to completely fill the semicircular structure with the adhesive. The original adhesive system When the filling rate is high, in the oven baking the paint curing adhesive, the pre-treatment process will make the water or air into the semicircular structure, with the adhesive curing Flow and other causes of adhesive overflow. Such a processing method is the cause of various problems. To solve this problem, preheating at a relatively low temperature, in a very short time gelatinization, to get a newly developed, easy to peel similar curing type adhesive. The adhesive is mixed in the liquid epoxy resin properties of acrylic powder, heating (120 ℃ above) acrylic powder and liquid epoxy resin to swell to form a rubber membrane.
 (9) The universal application of induction curing device For the curing of hemming glue, the induction curing equipment is widely used to solidify the workpiece (such as door, hood, trunk lid, etc.) in order to improve the production efficiency.
 (10) adhesive construction automation system widely used in foreign automobile factory, the adhesive coating equipment can be seen everywhere. From the welding of the plastic welding flange, rubber coating workshop coating, to the assembly shop glass adhesive, ceiling interior adhesives have been widely used. Due to the precise construction of automation equipment, in ensuring quality while also reducing the consumption of materials.
