Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the current ordinary printing rubber roller swells greatly in UV ink and its cleaning agent, and the UV printing rubber roller swells greatly in ordinary ink and its cleaning agent and cannot be interchangeable, and provides a UV ink and cleaning agent. The rubber compound used for the coating rubber of ordinary ink dual-purpose printing rollers has good swelling properties for both inks and cleaning agents, and its physical properties are comparable to those of the two rubber roller coating rubber materials

Embodiment 1

[0019] The sizing material formula of embodiment 1 and the quality proportioning of various raw materials are as follows:

[0020]

[0021] The preparation of embodiment 1 sizing material: first prepare respectively the master batch of preplasticized nitrile rubber / polyvinyl chloride blend (hereinafter referred to as master batch N) and the master batch of silicone rubber compound rubber (hereinafter referred to as master batch S) , Then masterbatch N and masterbatch S were blended in proportion to prepare the compound of Example 1. ①Preparation of masterbatch N: In the above formula, except for the silicone rubber compound, cerium oxide and dicumyl peroxide, other raw materials are measured according to the mass ratio, and then the blend rubber (1234E) is added to the internal mixer in sequence. , small materials (zinc oxide, stearic acid, anti-aging agent), other compounding agents (white carbon black, zinc methacrylate, coupling agent, titanium dioxide, carbon black, oin...

Embodiment 2

[0024] The sizing material formula of embodiment 2 and the quality proportioning of various raw materials are as follows:

[0025]

[0026] The preparation of embodiment 2 sizing material: 1. masterbatch N: same as embodiment 1; 2. masterbatch S: batching mass ratio is R701 / 8030, R701 / 4070, cerium oxide 10, dicumyl peroxide (40%) 2.5 , the rest of the operations are the same as in Example 1; ③ masterbatch blending: the mass ratio of the ingredients is masterbatch N312.15 and masterbatch S33.75, and the rest of the operations are the same as in Example 1.

[0027] The shaping of rubber roller, vulcanization and post-processing are identical with embodiment 1;

Abstract

The invention relates to a coating rubber sizing material of a dual-purpose printing rubber roller for UV (ultraviolet) ink and common ink. The sizing material consists of pre-plasticized butadiene-acrylonitrile rubber / polyvinyl chloride blend rubber, silicone rubber compound, precipitation-process white carbon black, zinc methacrylate, a polyester plasticizer, a plasticizer TP-95, a plasticizer TP-90B, sulfur, an accelerant, dicumyl peroxide and other auxiliaries. The sizing material provided by the invention has the characteristics that the swelling property is relatively good in the UV ink and cleaning agent thereof and common ink and cleaning agent thereof, and the physical property is equivalent to that of the coating rubber sizing material of the UV ink printing rubber roller and common ink printing rubber roller. The dual-purpose printing rubber roller made from the coating rubber sizing material can be conveniently replaced between the UV ink and the common ink, and can be applied to UV ink printing as well as common ink printing.

Description

technical field [0001] The invention relates to a coating glue material for a dual-purpose printing rubber roller of UV ink and common ink. Background technique [0002] In recent years, due to the environmental protection advantages of UV ink (ultraviolet curable ink), it has been more and more widely used in offset printing. The composition of UV ink and its cleaning agent is very different from that of ordinary ink and its cleaning agent. UV ink contains unsaturated resin prepolymers, reactive diluent monomers, photoinitiators, etc. Under the irradiation of ultraviolet rays, the prepolymers will be polymerized, cross-linked and grafted, and cured to form a film in a short time. Ink (also known as oil-based ink) contains natural or synthetic resins, mineral oil and vegetable oil (such as linseed oil), etc., and forms a film through surface oxidation, binder penetration and solvent volatilization during the drying process of the printed matter. UV ink cleaning agents are ...
