Silicone strip hardness

by:Kenna     2021-05-22
The hardness of the silicone strip is suitable for all kinds of doors, windows, etc. 2. The cabinet sealing strip has developed its own characteristics based on the use of electric cabinets and based on 20 years of experience in the research and development of sealing strips. It has the characteristics of good sealing, waterproof, fire-proof, insect-proof, wind-proof, light-proof, anti-collision and long service life. 1. The steel frame is three-composite, which is not easy to deform and shrink, the assembly is firm, and the sealing is good. 2. It is used for doors, windows and curtain walls. Sealing strip, the product has good elasticity, resistance to migration, can effectively block noise, dust, and weather. 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. Under normal circumstances, the hardness of silicone rubber strips can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application areas continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization (extruded After the rubber strip is cut to a certain length, it is put into a vulcanizing tank to vulcanize, and the semi-finished product of the extruded rubber strip is put into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, continuous hot air Several methods such as vulcanization). 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 times. 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. Material: 1. Made of high-quality EPDM rubber, made by foaming process, 2. The back is made of imported double-sided tape, and the interlayer is grid-shaped glass fiber. The scope of application and installation method: 1. The sealing strip of the electrical cabinet is made of good Elasticity and resistance to compression deformation, aging resistance, ozone, chemical action, wide use temperature range (-40℃~+120℃) EPDM rubber foamed and densely compounded, with unique content The metal clamp and tongue buckle are strong and durable. 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 hardness and durability of silica gel strips maintain stable performance and long service life in different environments, anti-aging, wear-resistant, non-wrinkle, non-stretching, non-stick paint surface, and will not be affected by high temperature and dust. Mildew and anti-ultraviolet and ozone erosion. Our value to you starts from your experience. It is durable and new forever. It is the real experience of users. The beautiful covered PU sealing strip is green and environmentally friendly, and it is stylishly sealed; it is a perfect solution for sealing and The contradiction of sound insulation achieves the dual effect of sealing and sound insulation; doors and windows are perfectly matched with products. 'Specialization' originated from Germany and has been popular in the European market for a long time. It is famous for its environmentally friendly sealing performance. The sound insulation, heat preservation, sealing, impact resistance and environmental protection characteristics of the coated sealing strip have been more and more Many consumers pay attention to 'functionality'. For a long time, German design has always been a well-functioning, rational and reliable image, especially the harmony and unity of the entire product in terms of technology, function, logic and sense of order. The sealing strip structure makes the door leaf and the door sleeve tight and seamless, and has stronger sound penetration resistance, and has strong resilience, sound insulation and environmental protection. According to the cross-sectional shape, the car sealing strip can be divided into solid core products (round , Square, flat cross-section shape), hollow products and metal rubber composite products, and secondly, the heat-aging resistance EPDM sealing strip has been tested many times before production. From the experiment, it can be seen that the product It can work continuously in a high-temperature environment without aging, so many companies use products to improve work efficiency, so as to obtain more profits. Technical features: 1. A kind of automotive product rubber, It is characterized in that the automobile product rubber is composed of EPDM rubber, carbon black, softening oil, processing aids, and accelerators. 2. The automobile product rubber according to claim 1, wherein the automobile product rubber The product rubber is calculated by weight ratio. EPDM rubber is 100, carbon black is 90, softening oil is 20, processing aid is 15, and accelerator is 5.
