Problems solved by technology

[0003] During the printing process of various printed products, a lot of noise will be generated. The noise mainly comes from the printing roller of the printing machine. noise pollution
At the same time, the staff works under the noise for a long time, which seriously damages the hearing of the staff. Therefore, green printing without noise pollution is a subject that people need to study.

Embodiment 1

[0023] A green printing process without noise pollution, comprising the following steps:

[0024] (1) Preparation of sound-absorbing panels: Add polyurethane, phenolic resin, EVA and dispersant to the autoclave, then add bentonite and kaolin that have been ground to pass through a 400-mesh sieve for mixing, heat up and melt for 1-1.5 hours, and then pour them into the autoclave Add foaming agent and nucleating agent, keep warm and infiltrate to make the material foam for 20-30 minutes, then pass carbon dioxide gas into the autoclave, keep pressure and infiltrate for 1.5-2 hours, then slowly release the pressure to normal pressure, and then put the mixture into the mold , through high-temperature steam molding, and naturally cooled to room temperature to obtain sound-absorbing panels for use;

[0025] (2) Preparation of adhesive: add epoxy resin, vinyl resin, polymethyl acrylate and sodium carboxymethyl cellulose into the melting furnace for melting, heat up and melt for 1-1.5h...

Abstract

The invention provides an environment-friendly printing process without noise pollution, and relates to the technical field of printing. The steps are as follows: preparation of a sound absorbing panel, preparation of an adhesive, preparation of a sound absorbing cover, and printing. The invention overcomes the deficiencies of the prior art, and the noise generated by the printing is reflected andweakened by a large number of different sound absorbing chambers by the sound absorbing cover, effectively reducing noise pollution, and lubricating a printing roller shaft by lubricating oil, thereby reducing the noise generation from the root, and preventing the staff from working under the noise for a long time and thus damaging the hearing, green and environmental protection is realized, andthe printing effect is good.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a green printing process without noise pollution. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, and pressurization to copy the contents of the original manuscript in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. [0003] During the printing process of various printed products, a lot of noise will be generated. The noise mainly comes from the printing roller of the printing machine. noise pollution. At the same time, the staff works under the noise for a long time, which seriously damages the hearing of the staff. Therefore, green printing without noise pollution is a subject that people need to study. Contents of the invention [0004] Aiming at...
