Rubber sealing strip can be classified according to section shape, vulcanization method, application position and application, and material.
According to vulcanization method
(1) Discontinuous vulcanization method (cut the extruded rubber strip according to a certain length, put it into the curing tank for vulcanization, and put the extruded rubber strip semi-finished product into the model for vulcanization);
(2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method and other methods).
A. Microwave continuous vulcanization compound sealing strip: microwave vulcanization technology is a production technology widely used and widely promoted after the energy crisis in the 1970s. Microwave continuous vulcanization technology can not only produce composite strips of metal core, solid core rubber and sponge rubber, but also has advantages over other continuous vulcanization devices in energy saving and improving work efficiency. This technology is recognized by the world as the best process for producing extruded products. The characteristic of microwave heating is that the heat is generated directly in the heated object instead of being input from outside as usual. This not only generates heat quickly, but also distributes evenly, which is beneficial to improve the product quality and greatly shorten the heating time.
B. Salt bath continuous vulcanization sealing strip: the salt bath system containing nitrite is adopted in salt bath vulcanization, which causes great environmental pollution
Gradually eliminated. Vulcanization (Tmax: 450 \u00b0 C and Vmax: 60m \/ s) can also achieve flame pretreatment, and the safety is greatly improved.
2\u3001 Classification according to rubber sealing strip material
There are three kinds of rubber materials for automobile sealing strip: dense rubber, sponge rubber and hard rubber.
The hardness of hard rubber can reach shore A95. The rubber compound of the sealing strip is mainly composed of ethylene propylene diene monomer (EPDM) with aging resistance, low temperature resistance, water vapor resistance and chemical corrosion resistance. EPDM can be compounded with steel belt, steel wire braided belt, TPE, flannelette, flocking, PU coating, silicone coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration reduction, abrasion proof and decoration functions of the automobile interior, the outside world and itself.
Generally, EPDM sealing strip can be used stably for more than ten years. Chloroprene rubber (CR) with good ozone resistance and aging resistance can also be selected. Considering the process properties of common rubber compounds, it is necessary to select and use rubber, such as natural rubber (NR), Cr and styrene butadiene rubber (SBR). Rubber or PE, EPDM and NR rubber and plastic were used to improve ozone resistance.
3\u3001 Application site
Automobile sealing strip, door and window sealing strip, ship sealing strip and mechanical sealing strip;
The mechanical sealing strip includes cabinet sealing strip, container sealing strip, etc. [1] The principle consists of sealing and installation. This kind of product mainly uses the elasticity of lip, cavity, flange and other parts of the body structure and the contact pressure generated by the surface of the assembled coupling parts (glass, metal parts, etc.) to seal and decorate. It is generally used in the range of – 50 ~ 70 \u2103. It is composed of sealing and installation.
