There are natural cracks and holes in some stone materials, which make the surface effect of plates poor and the breakage rate is high during processing and installation, especially in stone materials and some large plates. Therefore, unsaturated resin is introduced into the repair and reinforcement of stone.
The scientific name of unsaturated resin is unsaturated polyester resin. When a linear polymer compound condensed from a saturated or unsaturated dibasic acid and a saturated or unsaturated dibasic alcohol is dissolved in a monomer (usually styrene) and becomes a viscous liquid, we call it an unsaturated polyester resin.
Unsaturated polyester resin is a thermosetting resin, which can be cured into polymer network under the action of heat or initiator. Its application in stone repair and reinforcement is based on the following aspects: fast consolidation speed; Low viscosity and convenient operation; Light color and good transparency; The colloid has high hardness and good polishing performance; Simple preparation and low cost.
