Abstract

The invention discloses a special protective adhesive for PS/CTP plates, which is prepared from the following components in parts by weight: 3-4 parts of Arabic gum, 2-3 parts of peach gum, 1-2 parts of pineapple pectin, 3-4 parts of hydroxyethyl fibers, 0.1-0.2 part of peppermint essential oil, 1-1.5 parts of polyvinyl alcohol, 1-2 parts of a compound additive, and 75-85 parts of deionized water; and in the process of preparation, components in a formula are added into hot water, and then fully stirred and filtered. The special protective adhesive for PS/CTP plates disclosed by the invention has a good uniform coating property, so that a smooth protective film can be formed after a small amount of the adhesive is used; the special protective adhesive for PS/CTP plates has an extremely strong protection ability, so that the service life of printing plates is prolonged; and the special protective adhesive for PS/CTP plates is aromatic in smell, so that the adhesive can improve the working environment, and improve the work efficiency.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a special protective glue for PS / CTP plates and a preparation method thereof. Background technique [0002] The protection of printed PS / CTP plates is usually protected by special protective glue. Some existing protective glues form uneven protective films when they are painted, which reduces the protective effect and fails to achieve the purpose of extending the life of the printing plate. Contents of the invention [0003] The invention discloses a special protective glue for PS / CTP plates. The special protective glue for PS / CTP plates has good leveling property, can form a smooth protective film with very little dosage, has super strong protection ability, and prolongs the service life of printing plates. . [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A special protective glue for PS / CTP plate, which is charac...
