Preparation and Performance Study of Methacrylate Malate Photocurable Resins
Compared with the traditional thermosetting resin,light curable resin is a photo-sensitive resin with low molecular weight.It can change rapidly in physics and chemistry un-der UV irradiation.It has the characteristics of high energy utilization and low heat release.Therefore,we proposed a preparation method of synthesizing methacrylate malate light cur-able resin.Using the advantages of DL-malic acid multifunctional group,methacrylic acid was grafted on the side chain of the resin,and the effects of different content of DL-malic acid on the properties of the resin were studied.The synthesized resin contains unsaturated double bonds in the side chain.After adding photoinitiator,the resin can be cured in a short time under light.Because malic acid is close to succinic acid in structure,the synthesized resin has excellent mechanical properties,the elongation at break can reach up to 38.52%,and the breaking strength can reach up to 19.25 MPa.
