The price of high temperature resistant silica gel strip, the sealing strip
, is a product that seals a thing so that it is not easy to open, and plays the role of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixation. EPDM The rubber strip is formed by microwave vulcanization process at one time, the surface is smooth and beautiful, has good elasticity and resistance to compression deformation, weather aging resistance, ozone resistance, chemical resistance and a wide temperature range (-50℃~+150℃), etc. Performance has been widely used in manufacturing industries such as automobile doors, windows and curtain walls. Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. The price of high temperature resistant silica gel strip does not react with any paint or cleaning agent. Customers do not need to worry about the integrity and beauty of doors and windows being damaged. According to the composite structure of the rubber compound, it can be divided into pure rubber sealing strips-composed of a single rubber species ; The second composite sealing strip-composed of dense rubber and foam sponge rubber, often containing a metal skeleton material in the axial direction inside the dense rubber; three composite sealing strip-composed of two types of dense rubber (one of which is light-colored) and It is composed of sponge glue, usually containing a metal skeleton and reinforcing fibers inside the dense glue. It also has good dustproof, sound insulation and decorative effects, and also protects the car body, effectively improving the comfort of the ride. The characteristics of the car sealing strip are in the -40 ℃ low temperature resistance test, the sealing strip Does not harden, does not become brittle, still maintains softness and good adhesion of the rubber strip, showing excellent cold resistance, EPDM sealing strip performance characteristics: excellent overall performance, outstanding ozone resistance, excellent weather resistance Very good high temperature resistance, low temperature performance, outstanding chemical resistance, resistance to a variety of polar solutes, and low relative density. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass touch the glass, 3) It has an independent open-cell bubble structure, and the appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion. The shrinkage changes and changes to enhance the sealing, expansion, and water-stop effect of the joint. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety. For the price of high temperature resistant silicone strips, it is necessary to pay more attention to maintenance and to master the correct maintenance method, otherwise the maintenance effect will not be achieved. Let us understand the importance of car sealing strip maintenance together. The characteristics of the product The elasticity and compression resistance of the automobile sealing strip are very good, and it also has good resistance to aging, ozone and chemical effects, etc., making the product very strong and durable during use, and Installation is also very convenient. Automobile sound insulation and anti-collision strips are divided into 3M back-adhesive small D-shaped sealing strip, 3M back-adhesive large D-shaped sealing strip, 3M back-adhesive large P-shaped sealing strip, A, microwave continuous vulcanization composite sealing strip: microwave vulcanization technology is the 70s of the 20th century The production technology used and widely promoted after the foreign energy crisis in the 1940s, the use of microwave continuous vulcanization technology can not only produce composite strips of metal core, solid core rubber and sponge rubber, but also save energy and improve work efficiency. Other continuous vulcanization methods are superior. Among the raw materials for sealing strips, EPDM, the main raw material used in the past, is also constantly updated and developed. The new EPDM with excellent physical properties and good processing properties can control the long-chain branching in the molecule and make it The vulcanization performance is better, and the extrusion speed and the output of the product can be improved. These materials have the excellent engineering properties of elastomers and the excellent characteristics of plastics, which are convenient for processing and can be recycled and reused. These materials are gradually replacing EPDM. Products.
