Embodiment Construction

[0012] A kind of photocurable resin preparation method of rapid prototyping is characterized in that comprising the steps:

[0013] (1) Pour the epoxy resin into a flask equipped with a stirrer and temperature control facilities, and pass in nitrogen for protection, heat up, add hydroquinone inhibitor, and stir evenly;

[0014] (2) Weigh acrylic acid according to the ratio of epoxy resin to acrylic acid substance 1:2, add tetrabutylammonium bromide, stir until it is completely dissolved, pour it into a constant pressure dropping funnel, and start adding the mixed solution dropwise. About 2s per drop, slowly warming up;

[0015] (3) After the reaction is stable, take samples at intervals and measure the acid value, stop heating until the acid value is less than 5mg / g KOH, and the product is the resin produced.

[0016] In the method for preparing a rapid prototyping photocurable resin according to the present invention, the heating temperature in step (1) is 60-80°C. The heat...

Abstract

A rapid prototyping method for preparing light-curing resin belongs to the field of material preparation. It is characterized by comprising the following steps: pouring the epoxy resin into a flask with a stirrer and a temperature control facility, introducing nitrogen for protection, heating at the temperature, adding a hydroquinone polymerization inhibitor, and stirring evenly; The amount of resin and acrylic acid substance Weigh the acrylic acid, add tetrabutylammonium bromide, stir until it is completely dissolved, pour it into the constant pressure dropping funnel, start to drip the mixture, about 2s every drop, slowly heat up; after the reaction is stable Take samples at intervals and measure the acid value. When the acid value is less than 5 mg / g KOH, the heating is stopped, and the product is the prepared resin. Through the effective improvement of the process, the preparation method of the photocurable resin is simplified, and the low viscosity of the prepared resin is conducive to the rapid leveling of the resin, easy operation, high curing rate, which is conducive to improving the molding rate, simplifies the preparation process, saves money The preparation cost is reduced, and it is suitable for promotion and use in related fields.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to a method for preparing a rapid prototyping photocurable resin. Background technique [0002] With the rapid development of science and technology, rapid prototyping photocuring technology is a new green and environmentally friendly technology developed in the 1980s. It is a new technology that fundamentally changes the traditional manufacturing method and promotes the rapid development of the modern manufacturing industry. In the rapid prototyping photocuring technology, the photocurable resin directly affects the precision of the manufactured product and the performance of the product. Most of its preparation process still uses the experimental method of the laboratory, the process is relatively complicated, and it cannot be industrialized on a large scale, which affects the development of new technologies in related industries. Contents of the invention [0003] The pres...
