How much is the door sealing strip? All the above characteristics are also the advantages of foam sealing strips. Through understanding, we can find that the reason why this product is popular in the market is because the product has many characteristics and advantages. The temperature is very low. If a product such as a car seal is damaged, it is easy to allow air-conditioning to enter the car, and wind noise is also prone to appear. This sound feels like the car door is not closed tightly. Affect the comfort of the ride. 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 door sealing strip is also called fire-resistant silicone sealing strip and fire-resistant self-extinguishing silicone sealing strip. It is known for its good flame-retardant and self-extinguishing performance. The main process is to use high-quality silicone raw materials to make it through a large extruder. The molded silicone strip is then made through high room temperature vulcanization and drying. Compared with the general silicone strip, the high temperature resistant flame retardant silicone strip is different in that it needs to add flame retardant powder to the formula. Silicone strips have super flame-retardant and fire-resistant properties, and play a certain role in safety protection in the sealing of electronic appliances, so many people also call them fire-resistant sealing strips. Sealing strips are made of rubber, paper, metal, plastic and other materials. Low-end products use waste materials, substitute plasticizers and high filling levels, so that the strips have poor elasticity, easy to harden, and have a nasty smell. , Easy to migrate, make the frame material yellow, short service life, characteristics 1. EPDM has excellent weather resistance, weather resistance refers to long-term resistance to severe cold, heat, dryness, and humidity, and it is extremely corrosive to rain and snow. Good corrosion resistance can fully extend the service life of the rubber strip; 2. Heat aging resistance refers to strong heat-resistant air aging resistance. According to the material classification, the rubber materials of automobile sealing strips are compact rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shore A95. EPDM can be combined with steel belt, steel wire braided belt, TPE, flannel, flocking, PU coating, organic silicon coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration reduction, wear resistance and decoration effects of the car interior and the outside world and itself, and it can also choose to have good ozone resistance and good aging resistance Performance of neoprene (CR). 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.

According to the sealing characteristics, automobile sealing strips can be divided into weather sealing strips (WEATHERSTRIP) and general sealing strips (SEALING). Among them, weather sealing strips have hollow sponge foam tubes, which have better temperature and humidity maintenance function and are maintained in normal The process includes the following items. First, the detergent must be cleaned. After the cleaning is not done, a layer of protective agent must be applied. This can prevent aging and prevent dust.
