Abstract
The invention discloses a photocuring resin for investment casting in laser fast molding. The resin comprises the following materials in percentage by mass: 30 to 55 percent of unsaturated polyester, 20 to 35 percent of epoxy resin, 20 to 40 percent of active diluent and 1 to 6 percent of light initiator. A preparation process for the resin comprises the following steps of: adding the light initiator into the active diluent, dissolving in a water bath of 40 to 60 DEG C until the light initiator is transparent, adding the unsaturated polyester and the epoxy resin, and stirring and mixing for 1 to 2 hours. The resin has low viscosity, a mold shell does not crack during roasting, the thermogravimetric curve is flat in a roasting process, the gas evolution is uniform and the carbon residue is low.
Description
Technical field
The present invention relates to the light-cured resin technical field, be specifically related to moltening mold castings light-cured resin in a kind of laser fast shaping.
Technical background
Since rapid laser-shaping technique after rising the eighties, developed the light-cured resin of suitable different field both at home and abroad, for investment cast; The moulding process that is fit to it; Its resin must slowly be ablated in ablation process, and gas forming amount is steady, and remaining carbon is low.With reference to these requirements; Prepared the resin formula that is specifically designed to investment cast; Wherein bisphenol A epoxide resin is a most important composition in the resin system, affects the mechanical property of whole resin, but the benzene ring structure that it contains causes heat decomposition temperature height in ablation process; Therefore the shortcoming that remaining carbon is high can not solve the defective that causes the ceramic shell spalling at hot stage with it as matrix resin.In ablation process, because the thermal expansivity of resin and pottery differs an one magnitude, produce in narrow humidity province if add thermal weight loss, produce a large amount of gas this moment, is easy to cause the spalling of ceramic shell.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide moltening mold castings light-cured resin in a kind of laser fast shaping, it is low to have viscosity; Not spalling of shell when roasting; Thermogravimetric curve is mild in ablation process simultaneously, and gas forming amount is even, and remaining carbon is low.
