Abstract

The invention relates to a manufacturing technology for an air cushion printing rubber blanket on a printing roller of a hectograph machine, which adopts the technical proposal that the manufacturing technology comprises a plurality of ordinal steps as followings: firstly, coating a rubber glue on single side of a cotton cloth of a surface layer and drying the glue, calendering a rubber sizing material simultaneously on the both side of the rest cotton cloth of a middle layer, and calendering the rubber sizing material on the single side of the cotton cloth of a bottom layer; secondly, folding the cotton cloths coated the rubber glue or calendered the rubber sizing material, and compounding the cloths on a dual-roller compound machine directly; thirdly, vulcanizing the compounded rubber blanket; fourthly, and grinding the vulcanized rubber blanket. The invention is characterized in that the calendering rubber sizing material on the single or both side of the cotton cloths is proceed on a four-roller calender, the running speed of the calender is 3 to 5 meters per minute and the calendering temperature is 70 to 100 DEG C.

Description

technical field [0001] The invention relates to a blanket production process, in particular to an air cushion printing blanket production process on a printing roller of an offset printing machine. Background technique [0002] The blanket on the printing roller of the existing offset printing machine is a four-layer cloth and four-layer glue structure: its surface glue, inner layer glue and foam layer are all completed by steam coating; Rubber glue is coated on the cotton cloth and heated and dried with steam, then as shown in Figure 2, four layers of cotton cloth coated with rubber glue are compounded and vulcanized, and then the blanket is ground. This process not only wastes solvent (xylene or toluene) and steam, but also pollutes the environment, and is inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improvement in the production process of printing blankets. This production process should b...
