The energy consumption loss can account for 40% of the total energy loss in 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 taken as mandatory The performance acceptance indicators have also attracted great attention and implementation in various provinces, cities and regions across the country. Energy-saving doors and windows have become the mainstream of building doors and windows. 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 strips are hard and durable sealing strips, which seal a thing so that it is not easy to open, and play the role of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixation. EPDM rubber strips It is formed by microwave vulcanization process at one time, the surface is smooth and beautiful, has good elasticity and resistance to compression deformation, weather aging resistance, ozone resistance, chemical resistance, and a wide temperature range (-50℃~+150℃). It has been widely used in manufacturing industries such as automobile doors, windows and curtain walls. It is a kind of sealing strip that uses the characteristics of certain materials to make pores appear inside through processing. It is divided into EPDM foam sealing strips, silicone foam sealing strips, and PU foam sealing strips.

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.
