A kind of blanket reducing agent for printing

Abstract

The invention discloses a rubber blanket reducing agent used for printing. The rubber blanket reducing agent comprises, by weight, 60-70% of dichloromethane, 15-20% of terpilenol, 5-10% of 1,1,1-trichloroethane, 1-2% of sorbitan monostearate, 3-5% of triethylene glycol, 2-3% of cocofatty aid monoethanol amide, 0.5-1% of methyl lauroyl glucose esters, 4-6% of dipropylene glycol methyl ether and 1-2% of N-oleoyl-N-sodium methyl taurate. The reducing agent not only can rapidly flat concave faces generated on a rubber blanket in the printing process and eliminate the surface hardening phenomenon to recover original elasticity of the rubber blanket, but also can rapidly eliminate dirt, printing ink, oxidation films and the like, prolongs service life of the rubber blanket, improves printability of the rubber blanket, meanwhile, has the advantages of being rapid to volatilize and dry and free of benzene and does not leave remnant blots or damage human health.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a blanket reducing agent for printing. Background technique [0002] In the printing process, the blanket bears the transfer function of accurately transferring the graphic information on the printing plate to the paper. Not only does the blanket itself have good printability, it is important to maintain Excellent printability of the blanket. With the passage of time, paper fluff, paper powder, ink skin and other dirt will accumulate on the blanket, the printability will gradually decrease, and the quality of printed matter will also decrease, so the blanket should be cleaned in time. Nowadays, various blanket cleaning products such as gasoline and kerosene are used to clean the blanket. Although it can clean the surface stains (ink, paper wool, paper powder) of the blanket, it lacks the function of improving and restoring the printing suitability of the blanket and cannot be restored. The o...

Nowadays, various blanket cleaning products such as gasoline and kerosene are used to clean the blanket. Although it can clean the surface stains (ink, paper wool, paper powder) of the blanket, it lacks the function of improving and restoring the printing suitability of the blanket and cannot be restored. The original elasticity of the blanket does not restore the concave surface of the blanket that is pressed during printing, so that it cannot restore its elasticity and surface smoothness
