Abstract

The invention relates to a preparation method of epispastic material employing electron beam radiation crosslinking and compositions thereof; when the epispastic material is applied, foaming agent is added at the moment of mixing one thermoplastic high molecular compound and at least one thermoset rubber, the foaming agent is ensured to be homodispersed fully in the crosslinked polymer and then the crosslinking is carried out by electron beam irradiation. After foaming, the foaming is even and good, the crosslinking density is increased and the crosslinking time is reduced.

Description

technical field [0001] The present invention relates to a foaming material manufacturing method and its composition, especially to a foaming material manufacturing method and its composition using electron beam radiation cross-linking to improve the uniformity of foaming. Background technique [0002] Polyolefin foam material is a crystalline polymer (crystallinity about 30-70%), which is susceptible to permanent deformation due to external force, and does not meet the long-term elastic recovery requirements of end products such as sports and insoles, and polyolefin foam The material mainly uses the addition of peroxide to achieve the cross-linking effect of the polymer. The full effect of peroxide needs to last for 10-12 minutes at least 140 degrees, but the use of peroxide cross-linking agent is very harmful to the environment. , because the organic peroxide contains a divalent peroxy-O-O- structure, it can also be seen that "- +" is a derivative of hydrogen peroxide, in w...
