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. Silicone sponge strips, of course, rubber sealing strips can also be used in medical applications.

The packaging requirements are also based on the needs of the installation customers, so choosing this product can bring you Great convenience. Good airtightness and watertightness can realize the green and energy-saving of the building, prevent heat conduction, and realize the energy-saving and thermal insulation function of warm in winter and cool in summer. The coated sealing strip keeps you away from the hustle and bustle of the world and gives you a A quiet and comfortable life, here, we have a covered sealing strip, which can meet the use of people of all ages, from the moment you are born, to accompany you throughout your life! Choosing a covered seal, choosing a quiet life, happiness is so simple! . The characteristics of automobile sealing strips In the -40℃ low temperature resistance test, the sealing strips do not become hard or brittle, and still maintain softness and good adhesion of the strips, showing excellent cold resistance. The automotive sealing strips are mainly composed of It is made of ethylene propylene diene monomer (EPDM) rubber with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃). Contains unique metal clamps and tongue buckles, which are durable and easy to install. 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. Silicone sponge strips Silicone sealing strips can also be glued to materials with smooth surfaces because of its high shock resistance and waterproof performance. According to the compound structure of the rubber material, the car sealing strips can be divided into pure rubber sealing strips-a single type of rubber Composition; two composite sealing strips-composed of dense rubber and foam sponge rubber, often containing metal skeleton materials in the axial direction inside the dense rubber; three composite sealing strips-composed of two types of dense rubber (one of which is light-colored) It is composed of sponge glue and usually contains a metal skeleton and reinforcing fibers inside the dense glue. Where can it be used? Wooden windows, aluminum clad wood, aluminum alloy doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, Bronze doors, cast aluminum doors, plastic steel doors and windows, etc., 035W/m2K; 5. Fatigue resistance test: imitating window opening and closing 500,000 times, no obvious change in shape 6. Sound insulation test: only IV68 windows with intermediate strips, reducing noise 7. The IV76 window with intermediate and additional adhesive strips can reduce noise by 45 decibels. 8. Outdoor aging resistance test: It has been more than 20 years and the performance remains intact. The series of products are environmentally friendly products and do not contain CFC harmful substances. According to the cross-sectional shape, it can be divided into solid core products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products. Among them, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips The cross-section design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force. According to the sealing characteristics, they can be divided into weather seals. Strip (WEATHERSTRIP) and general sealing strip (SEALING).
