Photosensitive resin model and its post-processing method

Abstract

The invention provides a photosensitive resin model and a post-processing method thereof, and belongs to the technical field of photosensitive models. The post-processing method of the photosensitiveresin model comprises the steps that at least one photosensitive resin model is provided; the surface of each photosensitive resin model is coated with active agents and then is dried; and the photosensitive resin models are annealed. The photosensitive resin models prepared by the post-processing method of the photosensitive resin model are small in inner stress, and when the photosensitive resinmodels are applied to the photoelasticity technical field, the initial stress fringe order is small, and the photoelasticity test precision is high.

Description

Technical field[0001]The present disclosure relates to the field of photosensitive resin models, and more particularly to a photosensitive resin model and a subsequent treatment method.Background technique[0002]The optical elastic test is currently a valid means of verifying finite element analysis calculation results. The photoelastic test object is a photoelastic model. The quality of the photoelastic model is an important factor affecting the accuracy of light elastic test. The photosensitive resin model of direct molding of laser rapid molding techniques is one of the direction of research at home and abroad, which has a low cost, fast and environmentally friendly. In recent years, domestic photosensitive resin model production techniques have begun to promote application in the field of light elastic test in non-aeroquerination products. When the technology is applied to the plane of the avionics core machine and the technical verification machine stage thin-walled member, the ...

Problems solved by technology

However, due to the difference in the performance of different grades of photosensitive resins, the model post-processing processes of different grades of photosensitive resins may not necessarily be shared.

If the model of a certain grade of photosensitive resin directly adopts the processing method of other grades, it is easy to reduce the order of initial stress stripes and cause unsatisfactory conditions, and cause large experimental errors

Therefore, although there are some methods for reducing the order of the initial stress stripes of the photosensitive resin model in the prior art, there are still many brands of photosensitive resins prepared by the photosensitive resin model without suitable processing methods.

For example, the brand is 11122# photosensitive resin as a photosensitive resin model material with good optical and mechanical properties, and the photosensitive resin model prepared by it has no effective way to reduce the order of initial stress streaks
