Abstract

The invention discloses a solvent-free environment-friendly printed rubber blanket and a production process thereof. The solvent-free environment-friendly printed rubber blanket comprises surface cloth, middle cloth and bottom cloth. The solvent-free rubber blanket disclosed by the invention is reasonable in structure, and various solvents such as methylbenzene are not used; the rubber blanket isproduced by directly using a blanket discharging method, so that the rubber blanket is environmentally friendly. Furthermore, the rubber blanket has the characteristics of effective compressive property, quick restoration, high viscosity and no retention of any adhesive; no matter at a network point or on a full page, ink can be conveyed more stably.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a solvent-free and environment-friendly printing blanket and a production process thereof. Background technique [0002] The blanket is the covering of the transfer cylinder on the offset printing machine, and it is an integral part of the packaging material. A blanket is a composite article of rubber coating and substrate used to transfer ink from a printing plate to a substrate in indirect lithography. The main component of the existing rubber coating is NBR, and the base material is mainly fiber fabric. [0003] The blanket plays an important role in the process of printing with the transfer unit. The blanket has effective pressure resistance, fast recovery, strong viscosity, and does not leave any sticky matter, whether it is a dot or a full page. Both can make the ink transfer more stable. [0004] At present, the production of solvent-free environment-friend...
