The invention uses the chlorinated butyl rubber as the main material of the rubber layer, which endows the product with better heat resistance and toughness, and increases the use times and storage stability.

Background
The equalizing plate is an important auxiliary material in the vacuum bag autoclave forming process, and is mainly a plate profile placed on the surface of a prepreg layering. The pressure equalizing plate has the main effects that in the thermosetting process of the prepreg, the prepreg is stressed more uniformly by means of the gravity of the pressure equalizing plate, the temperature transmission is more stable, and the surface of the cured composite material is smoother. At present, in the can feeding process, steel plates, aluminum plates, paperboards, silicon rubber, acrylic rubber and the like can be used as equalizing plates.
In the use process of the equalizing plate, the most important is that the equalizing plate has good ductility, thermal conductivity, heat resistance and certain flame retardance, in the current aerospace autoclave process auxiliary material market, the provided equalizing plate is always gradually crosslinked under the action of a vulcanizing agent in the autoclave high-temperature high-pressure vulcanization process, but the toughness (the toughness is determined by the elongation and strength, the larger the strength is, the better the elongation is), the weaker the toughness of the vulcanized equalizing plate is, the cracking occurs at the position with certain radian and edge angle after repeated use for a period of time, the characteristic of repeated use is lost, the main reason is that the unvulcanized equalizing plate has poor heat resistance, the equalizing plate manufactured by using the chlorinated butyl has better heat resistance, and the equalizing plate manufactured by using the brominated butyl has poor storage stability, because bromine is more active, and meanwhile, the thermal conductivity of the equalizing plate in the current market is general, and the prepreg such as carbon fiber cannot be heated uniformly in the autoclave use process, so that certain differentiation, layering, bridging and other diseases can occur to the final product.
At present, the brominated butyl is used as main rubber in the high-heat-conductivity high-wear-resistance flame-retardant composite rubber equalizing plate, the heat resistance is inferior to that of chlorinated butyl, the vulcanized equalizing plate has weaker toughness, and after the vulcanized equalizing plate is repeatedly used for a period of time, cracking occurs at a certain radian and edge angle, so that the characteristic of repeated use is lost.
