Polyurethane matrix resin has made contributions to lightweight.
with the continuous development of science and technology, polyurethane technology has gradually matured, and light structure technology is increasingly important in the automotive industry, because these technologies help to reduce the weight of the vehicle. Through the development of its new slider, the scale instigated by the pointer is the 1-half polyurethane matrix resin Loctite max3 of the reciprocating stroke of the lower gripper, Henkel has taken another important step towards the fully automated mass production of composite components in the automotive industry
the global market leader in adhesives, sealants and surface treatment technology, the impact knife of Jinan Shijin low-temperature groove is generally installed and fixed with screws. By cooperating with kraussmaffei of Germany, Henkel has developed a component manufacturing process based on glass fiber or carbon fiber, and uses high-pressure RTM (hp-rtm) technology to create a high-quality surface for automotive body exterior decoration
improve the temperature resistance immediately after demoulding
compared with the epoxy resin often used in RTM (resin transfer molding) process, the polyurethane matrix resin technology developed by Henkel significantly improves the curing speed. Due to the low viscosity of polyurethane matrix resin, the resin is easier to penetrate into fiber materials, resulting in less splitting, which shortens the injection time and thus shortens the batch production cycle time. The outstanding toughness of Loctite max3 is also conducive to obtaining an optimized component structure
Henkel also improves the temperature resistance of polyurethane resin, so that Loctite max3 can be comparable to epoxy resin in this special property. High temperature resistance means that fiber reinforced composites can demould more quickly. The internal release agent ensures that the components can be easily separated from the mold, so that the surface quality of the synthetic material is excellent enough to realize immediate spraying and bonding. This accelerates the production process and ensures the production of externally visible components with excellent surface quality
realize flexible integration within the framework of integration concept
especially for the automotive industry, a complete set of solutions that can be integrated into an overall system is very important for the technology to achieve application readiness. Therefore, Henkel provides self-made adhesives to ensure the reliable joint process of different component materials within the framework of the advanced composite concept. If these adhesives are to give full play to their potential role, it is necessary to ensure that the different elements are perfectly coordinated
Frank Deutschl nder, global marketing manager of the Automotive Department of henkelag AA, said: Loctite max3 now enables us to have such a matrix resin system, which can further improve the feasibility and attractiveness of using composite materials to manufacture automotive parts. Through close cooperation with Klaus mafi, we have optimized the performance of the resin, so that both paint coatings and adhesives can be applied to the surface of synthetic composite materials without any pretreatment. Henkel's adhesive portfolio provides a complete system solution to ensure the production and integration of automotive synthetic components
the roof part of the driving roadster R1 model uses this kind of carbon fiber material model with light weight and high strength. This innovative production process will appear at the world's most important trade fair (k exhibition) of the plastic and rubber industry held in Dusseldorf, Germany, from October 16 to 23
in order to meet the strict requirements of exhaust emission reduction, and as a way to reduce fuel consumption and CO2 emissions, light structure technology is increasingly becoming a necessity. The packaging materials based on carbon fiber or green plastic should not only be hygienic and environmental friendly, but the composite materials of glass fiber combine lightweight and high strength to provide excellent performance closely related to safety and collision avoidance
up to now, the use of lightweight components is still limited. These components are limited by the requirements of the automotive industry related to cycle cycles and automation levels. In particular, the necessary surface post-treatment procedures in subsequent spraying are too time-consuming and must be completed manually. Therefore, composite materials are rarely used in the production of external components of vehicles
Klaus Murphy, a leading manufacturer of mechanical equipment for plastic manufacturing and processing, in conjunction with Henkel, a matrix resin expert, and R hlpuromergmbh, a globally active independent developer of polyurethane systems, have successfully produced composite components with surface quality suitable for direct painting by fully automated processes. This result benefits from the three component polyurethane matrix resin system Loctite max3 developed by Henkel, which not only contains resin and curing agent, but also contains high-performance internal release agent matching with the self shedding polyurethane varnish of R hlpuromer GmbH
therefore, Henkel, together with dieffenbacher of Germany, Zoltek of the United States, chomarat, R hlpuromer, ALPEX, m hlmeier and Roding automotive, has become a member of Klaus Maffei's professional partner network and is committed to establishing a mature and reliable production chain, including fibers, matrix materials and finished products
