Abstract

The invention discloses a thermo-sensitive non-grain plate and a manufacturing method for the thermo-sensitive non-grain plate. The thermo-sensitive non-grain plate is formed by a support body, a hydrophilic layer and a thermo-sensitive layer, wherein the support body is coated with the hydrophilic layer and the thermo-sensitive layer in sequence. The surface of the support body is coated with nano-sized particles and / or micron-sized particles or combinations containing the nano-sized particles and / or the micron-sized particles, so that a hydrophilic coating is obtained and has proper roughness, and in this way the surface of a plate substrate has hydrophilicity and a water-retaining property. Due to the nano-sized and / or the micron-sized hydrophilic particles in the hydrophilic layer, not only is the requirement for ink absorption satisfied, but also the abrasion resistance of the surface of the plate substrate is improved, and meanwhile the bonding force between the hydrophilic layer and the support body and the bonding force between the hydrophilic layer and the thermo-sensitive layer are both good. According to the thermo-sensitive non-grain plate, the manufacturing method for the thermo-sensitive non-grain plate and the application of the thermo-sensitive non-grain plate, an improvement is made to an existing thermo-sensitive plate, so that the performance of the existing thermo-sensitive plate is improved; moreover, the environmental pollution caused by acid and alkali waste liquid produced in the process of electrolyzing and oxidizing an aluminum plate by the existing thermo-sensitive plate is avoided, meanwhile, water consumption is saved by 70%, and power consumption is saved by about 50%.

Description

technical field [0001] The invention belongs to the technical field of printing plate preparation, and in particular relates to a heat-sensitive non-gritty printing plate and a preparation method thereof, which are applied in the printing field. Background technique [0002] There are three main types of digital printing technologies: silver halide technology, high-sensitivity technology, and the latest heat-sensitive technology. The digital offset printing plate made by heat-sensitive technology is called heat-sensitive plate. The photosensitive range of the thermal version is 830-1064nm, or even wider. The production process of the thermal plate is: plate base cleaning - degreasing - cleaning - electrolytic sand mesh - washing - ash removal - washing - oxidation - washing - sealing - washing - drying - coating solution - drying - cutting - Package. The working principle of the thermal plate is: when the infrared laser of the thermal plate-making machine scans the plate,...
