Embodiment Construction

[0007] The present invention is a kind of preparation method of spraying photosensitive heat-sensitive CTP plate, and it uses aluminum plate as base plate, and it comprises the following steps, step 1, put base plate into sodium hydroxide aqueous solution to wash first, then wash with water, Remove the dirt on the surface; step 2, put the cleaned base plate into the electrolytic tank and use hydrochloric acid as the electrolyte to perform three-phase electrolysis on the base plate, forming a multi-layer fine and uniform sand mesh layer; step 3, after electrolysis Clean with clear water; Step 4, put the substrate into sulfuric acid solution, anodize the surface of the substrate, coat the oxidized substrate with a connection layer, and then clean it with clean water; Step 5, connect The heat-sensitive resin layer is coated on the layer, and the heat-sensitive resin layer is a temperature-sensitive polymer coating selected through a synthetic sieve through the principle of heat-ac...

Description

technical field [0001] The invention relates to a method for making a spray-coated photosensitive thermosensitive CTP plate. Background technique [0002] The current photosensitive thermosensitive CTP plates have the following defects: (1) The general CTP plate production line uses extrusion coating, which is easy to form thicker coating edges and affects plate making. It is reported in China that the advanced CTP plate production line is equipped with vertical trimming devices on both sides on the basis of horizontal cutting devices to solve the problem of coating edges, so as to meet the requirements of automatic plate making machines. However, multi-knife cutting affects the accuracy of cutting size, resulting in waste of resources and high cost; (2) The traditional CTP coating process requires secondary coating, so two coating machines are required, one for hydrophilic coating Layer, a photosensitive solution is also a waste of coating.
