Silicone strip welding

Silicone strip welding, characteristics of automobile sealing strip In the -40℃ low temperature resistance test, the sealing strip does not become hard, not brittle, and still maintains softness and good adhesion of the rubber strip, showing excellent cold resistance, automotive sealing The strips are mainly composed of EPDM rubber foaming and dense compounding with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃). It is made of unique metal fixture and tongue buckle, which is durable and easy to install. 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. If the odor of the silicone strip is very strong, it is not a regular PVC. The sealing strip is a frequently used product, which is made according to a special process and special materials. The function of the sealing strip is to play a seal. It can effectively protect the performance of utensils. It is an indispensable part of many products. It can be said that it is indispensable, and it has played a great role. We cannot ignore it. Another point is that it does not absorb water. Therefore, it is also a material that replaces traditional asphalt. It is not because of its water resistance that it will not be saturated under high water pressure. Another point is that it is more environmentally friendly on the entire material. Human body causes any harm. 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. 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. For this reason, the GB12002-89 'Sealing Strips for Plastic Doors and Windows' was formulated very early to standardize the production and inspection of sealing strips. However, the quality and price of rubber and plastic sealing strips for doors and windows in the building materials market are very confusing. , Four-composite sealing strip-Our company takes the lead in the domestic development and production of a composite sealing strip composed of 4 kinds of rubber materials, and a thin protective layer of glue is coated on the surface of the foam rubber (bubble tube). Thereby further improving the service life of the seal. 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. The good airtightness and watertightness of the silicone strip can realize the green and energy-saving of the building, prevent the conduction of heat, 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 chaotic world Give you a quiet and comfortable life, here, we have a covered seal, which can meet the use of people of all ages, from the moment you are born, with you throughout your life! Choosing a covered seal, choosing a quiet life, happiness is so simple! . Talking about the important role of epdm for doors and windows. With the further development of science and technology and the continuous improvement of living standards, and the call of an energy-saving harmonious society that has been advocated, we all know that doors and windows are the eyes of the building, and its energy loss can be It accounts for 40% of the total energy loss of buildings, which has attracted enough attention, especially in large cities like the capital Beijing. In 2004, the heat transfer coefficient of doors and windows (indices for heat preservation and energy saving) was used as a mandatory acceptance index. Provinces, cities and regions across the country have also attracted great attention and implementation, and energy-saving doors and windows have become the mainstream of building doors and windows. In fact, there are many places in our lives that cannot be separated from this product, because its use effect is very good, friends who don’t know can join me to take a look at the characteristics of EPDM sealing strip. Third, ozone resistance The ozone resistance of the product is very good, and it can be completely exposed to the air to work, so that the superiority of the product is more prominent, and the anti-ultraviolet radiation effect of the EPDM sealing strip is also very good. Yes, but also has excellent physical and mechanical properties, so it is often used to make airplanes, trains, cars, and so on. Technical features: 1. An automobile product rubber, characterized in that the automobile product rubber is composed of EPDM, carbon black, softening oil, processing aids, and accelerators. 2. The automobile product rubber of claim 1, wherein the automobile product rubber is based on a weight ratio of 100 for EPDM, 90 for carbon black, 20 for softening oil, and 15 for processing aids. , The accelerator is 5.
