Dental plastic light curing compound material dowel and preparation method thereof

[0031] Example 1: Weigh 80 grams of bisphenol A bisglycidyl methacrylate into a small glass and store it in a vacuum oven at 60°C. Weigh 0.6 g of methacrylate, 1 g of ethyl p-aminobenzoate, 0.15 g of azobisisobutyronitrile, 20 g of methyl methacrylate, dissolve in 20 g of dimethacrylate triethylene glycol In the ester, stir evenly to obtain mixture A. Mix mixture A and bisphenol A diglycidyl methacrylate evenly, and store in the dark at room temperature for 15 minutes to obtain mixture B. The mixture B was diluted with 130 grams of acetone, and the unidirectional high-strength glass fiber was impregnated to obtain a prepreg. Leave the prepreg in the air until the acetone volatilizes until it is not sticky to the hands, and lay it in the mold according to the size of the mold. After the prepreg is fully covered, it is light-cured for 2 hours, and the required preformed fiber post is obtained.

[0032] Example 2: Weigh 85 grams of bisphenol A diglycidyl methacrylate into a small glass and store in a vacuum oven at 60°C. Weigh 0.8 grams of camphorquinone, 1.2 grams of ethyl p-aminobenzoate, 0.26 grams of dibenzoyl peroxide, 15 grams of hydroxyethyl methacrylate, dissolve in 25 grams of triethylene glycol dimethacrylate , stir evenly to obtain mixture A. Mix mixture A and bisphenol A diglycidyl methacrylate evenly, and store in the dark at room temperature for 15 minutes to obtain mixture B. Mixture B was diluted with 150 grams of ethanol and impregnated with unidirectional E-glass fibers to obtain a prepreg. Leave the prepreg in the air until the ethanol volatilizes until it is not sticky to the hands, and lay it in the mold according to the size of the mold. After the prepreg is fully covered, perform UV curing for 2 hours, and slowly take the fiber prepreg out of the mold. That is, the required preformed fiber post is obtained.
