Resin curing of polyester resin

There are two kinds of room temperature curing and thermal curing: ① room temperature curing, adding initiator (such as benzoyl peroxide, cyclohexanone peroxide, etc.) and accelerator (such as N, N-dimethylaniline, cobalt salt) to the above unsaturated polyester solution, so that the polyester solution can form gel at room temperature before curing. ② Heat curing can be achieved by adding only benzoyl peroxide initiator and heating to around 100 ℃. Whether it is room temperature curing or thermal curing, the reaction is initiated by the primary free radicals generated by the decomposition of the initiator to polymerize styrene, forming the active free radicals of the oligomer, and then connected to the double bonds on the unsaturated polyester main chain for copolymerization and crosslinking reaction. In addition, UV, electron beam γ Radiation curing, such as radiation.
