With the continuous development of science and technology, polyurethane technology has gradually matured, lightweight construction technology in the automotive industry is increasingly important, because these techniques help reduce vehicle weight of car. By developing its new polyurethane resin Loctite (Loctite) MAX3, Henkel (Henkel) to the car industry fully automated batch production of components of composite materials is an important step.
Adhesives, sealants and surface treatment technology of the global market leader in henkel by hand in hand to German Klaus murphy (KraussMaffei), has been developed based on glass fiber or carbon fiber components manufacturing process, using high pressure RTM (HP - RTM) technology for car body exterior trim surface of good quality.
After demoulding instantly improve heat resistance performance
Compared with the RTM (resin transfer molding) process using epoxy resin, polyurethane resin technology developed by henkel sharply improve the curing rate. Because of polyurethane resin viscosity low, more easily penetrate into the resin fiber material, produced by the split less, so as to shorten the injection time, and shorten the production cycle time. Loctite MAX3 outstanding toughness but also to get the component structure optimization.
Henkel also improves the temperature resistance of polyurethane resin, so that the loctite MAX3 ascend into in the special property on the height of the comparable with epoxy resin. High temperature resistant performance means that the fiber reinforced composite material can release more quickly. From the internal release agent to ensure that the components and mould easily, so that the surface of the composite material quality excellence enough, realize immediately coating and adhesive. This speeds up the production process, and make sure can produce excellent surface quality of externally visible components.
Flexible integration in the integration concept within the framework of implementation
Especially for the auto industry, can be integrated in a whole package of technology application in place is very important. Therefore, henkel provide independent manufacture of adhesive, designed to ensure that the advanced composite material within the conceptual framework of reliable joint of materials of different components. If these adhesives to give full play to their potential role, you need to ensure that various elements to get perfect coordination.
Henkel (HenkelAG&Co. KGaA) car department manager Frank Deutschl global market? Nder said: "the loctite MAX3 now that we have such a matrix resin system, it can further enhance the use of composite materials manufacturing feasibility and attractiveness of auto parts.
By working closely with Klaus murphy, we have to optimize the performance of the resin, so the paint coating and adhesive can be applied to synthesis of the surface of the composite material, without any pretreatment." Henkel adhesive products portfolio provides complete system solutions, to ensure that the car component production and integration of synthetic material.
Roding Roadster R1 top part of the model is to use this kind of light weight, high strength carbon fiber material model, the innovative production technology will debut on October 16 to 23 in Dusseldorf, Germany plastic and rubber industry of the world's most important trade fair exhibition (K).
In response to face the strict exhaust emission reduction requirements, and as to reduce fuel consumption and a way to reduce CO2 emissions, lightweight construction technology is increasingly becoming a necessity. Based on the carbon fiber or glass fiber composite materials combining lightweight and high strength, provides outstanding performance which is closely linked with the safety and collision avoidance.
Until today, the use of lightweight components also. These components by the auto industry and limit cycle and automation related requirements. Especially necessary in subsequent spraying the surface of the post-processing program is too time consuming, and must be finished by artificial, therefore, the composite material rarely applied in the production of external components of the vehicle.
For a leading manufacturer of plastic manufacturing and processing to provide mechanical equipment, Klaus murphy, a joint expert henkel and global active matrix resin polyurethane system independent developers RuhlPuromerGmbH, has been successfully rely on automated processes directly spray paint surface quality is suitable for producing composite material components. The results from henkel development department of three component polyurethane resin system loctite MAX3 - its not only contains resin and curing agent, also contains match since the loss of RuhlPuromerGmbH type polyurethane varnish of high-performance internal mold release.
Therefore, henkel, along with Germany difen Bach (Dieffenbacher), the United States drow teck (Zoltek), Chomarat, RuhlPuromer, Alpex, Muhlmeier and Roding Automotive - has become a Klaus murphy a member of the professional partner network, is committed to establish a mature and reliable production chain, including the fiber and matrix materials and finished products.
