preparation example Construction

[0011] The preparation method of the regenerated flexible solid photosensitive resin plate is:

[0012] The waste resin mixed in the solvent, that is, the liquid resin, is first used to recover the solvent by a recycling machine and filter it. Carry out tests, and then carry out targeted technical treatment according to the above technical solutions, waiting to enter the forming process.

[0013] Using the existing rubber and plastic equipment such as coating, extrusion, calendering, compounding, etc. in the market, and the existing traditional processing technology to carry out the required molding, the flexible photosensitive resin plate that meets the quality requirements can be produced.

Embodiment 1

[0016] Use a recycling machine to recover the solvent from the waste resin, dry it, and completely eliminate the volatile solvent. A standard flexible solid photosensitive resin plate support film is used for the resin, and the protective film is sandwiched in the middle, put into a flat vulcanizing machine, and a 2mm thick sheet is formed at 100 degrees.

Embodiment 2

[0018] According to the test data, the harmful impurities affecting the cross-linking and curing in the waste resin exceeded the standard five times, and the corresponding liquid was used to clean and extract, and it was repeated five times. Then select and add calcium oxide, acrylate, an appropriate amount of photosensitizer, polyurethane mixture, one or more of PVA and ethylene, vinyl acetate polymer to mix and mix evenly, and form a 2mm thick sheet in the same way as in Example 1. material.

Abstract

The invention relates to a regenerative flexible photosensitive resin plate. Currently, the flexible photosensitive resin plate is widely used for printing of carton boxes and flexible package printing material; generally, the flexible photosensitive resin plate is used for placing a negative image film with patterns or words on an unexposed flexible plate containing a photosensitive resin layer to be exposed with ultraviolet light; through ultraviolet irradiation, the solubility difference of solvents of a transparent part and an opaque part of the negative image film occurs, and a relief image containing the word patterns is obtained by cleaning and brushing; and the resin removed by cleaning and brushing is mixed in the solvent, the solvent is recycled through high temperature, and the resin and a part of solvent are abandoned as waste. Such waste resin is buried in the ground and cannot be rotten for hundreds of years, and a part of solvent also pollutes underground water and air; the waste resin reaches 30-50% of the purchase volume every year; and great harm is brought to the environment with the increasing use of the resin; and now the environmental protection department only charges environmental fees as a limitation way. The invention aims to protect the environment, waste resin pollution of the industry is prevented, the waste is utilized, and favorable economic benefit is achieved. The invention creates the flexible solid photosensitive resin plate using waste and old materials to produce and a preparation method of the flexible solid photosensitive resin plate.

Description

technical field [0001] The invention relates to a flexible photosensitive resin plate, in particular to a flexible solid photosensitive resin plate produced by comprehensively utilizing waste and old materials and a preparation method thereof. Background technique [0002] At present, flexible photosensitive resin plates are widely used in the printing of cartons, flexible packaging, and other substrates. [0003] Typically, a negative film with a pattern or text is placed on an unexposed flexographic plate containing a photosensitive resin layer and exposed to ultraviolet light. The transparent part of the negative image film is irradiated by ultraviolet light, and the relief image containing the text and graphics is obtained by washing and brushing by using the difference of their solubility in the solvent. After washing and brushing, part of the resin is mixed in the solvent, the solvent is recovered at high temperature, and the resin and part of the solvent are discarde...
