Which is better, door stitch top or silicone?

by:Kenna     2021-03-20
Which one is better for door seam strips or silicone? In the past, traditions have always paid more attention to materials and workmanship, ignoring the attention to humanization in use. What are the performance advantages of coated sealing strips? 1. Compression deformation test: 70 Compression rate of 50% at ℃ for 22 hours continuous compression, deformation rate ≤ 10% 2, compression force test, under 25% compression rate, 15N/100mm force applied, compression rate ≤ 10N3, temperature range test: from- There is no significant change in sealing performance from 40°C to 90°C. 4. Thermal conductivity K value test: K value ≤ 0 at 0°C. Automotive product rubber formula and its preparation method and process Background technology: The low temperature performance of rubber products currently used in automobiles on the market is generally low -25℃, but in a harsh climate, the rubber parts on the car cannot withstand the airflow of the cold air, which causes the product life to be greatly reduced. The performance of the rubber products used in the car directly affects personal safety, such as the previous Toyota The recall of some of the sold cars caused serious reputational consequences due to the problem of auto parts in the year. Therefore, all automobile manufacturers need a rubber product with long-term stable performance and sufficient safety. Which is better for door seam strips and silicone? Under high temperature, the weather resistance of the sealing strip is still good, and the elastic performance is maintained. The shape and function are not affected. The low temperature elasticity, the temperature when the tensile capacity reaches 100MPa is -58. The characteristics of the neoprene sealing strip: Compared with special rubber, the individual performance is worse, but the overall performance balance is good. It has excellent weather resistance, ozone resistance, heat aging resistance, oil and solvent resistance, good chemical resistance and excellent flame resistance. The auxiliary seal of the compensation ring is a metal bellows, which is called a bellows mechanical seal. 2. The composition of the mechanical seal: mainly includes the following four types of components, a. The main seals: moving and static rings, b, Auxiliary seals: sealing ring, c, compression parts: spring, push ring, d, three. At the same time, put the PVC sealing strip and the silicone rubber sealing strip in the freezer compartment of the refrigerator. After a few hours, the PVC sealing strip will become feel It is very stiff, easy to break, and the physical properties of silicone rubber sealing strips are unchanged. The sealing strips are made of rubber, paper, metal, plastic and other materials. Low-end products use waste materials, substitute plasticizers and high filling content. To make the rubber strips have poor elasticity, easy to be hard, have a nasty smell, easy to migrate, make the frame material yellow, and have a short service life. Features 1. EPDM has excellent weather resistance and weather resistance means long-term resistance to severe cold and heat , The ability to be dry and humid, it has excellent corrosion resistance to the erosion of rain, snow and water, which can completely extend the service life of the rubber strip; 2. Heat aging resistance refers to strong heat-resistant air aging. Technical realization Elements: 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 harsh climate, and guarantees good performance, thereby ensuring the human body 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 and can withstand the harsh climate. The invasion of cold air guarantees good performance and personal safety. Which one is better, which is better for door seam strips or silicone? 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. The characteristics of sound insulation, heat preservation, sealing, impact resistance and environmental protection have attracted more and more consumers' attention. 'Functionality' has long been a functional, rational and reliable image of German design, especially The whole product is in harmony and unity at the level of technology, function, logic and sense of order. 'The covered sealing strip structure makes the door leaf and the door sleeve tight and seamless, blocking sound penetration, and has strong resilience and sound insulation. Performance and environmental protection. 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, the metal rubber composite sealing strip accounts for more than 60%. The cross-section design of the rubber sealing strip 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 car window glass with the same and appropriate force. They are classified according to the sealing characteristics. It can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). Technical features: 1. An automobile product rubber, characterized in that the automobile product rubber is composed of EPDM, carbon black, softening oil, It is composed of processing aids and accelerators.
