Embodiment Construction

[0012] The protective layer formula for printed matter disclosed by the invention is characterized in that each group of formula composition includes the following components: 40-60% room temperature cross-linking polyacrylate emulsion, 2-7% styrene-acrylate resin liquid, waterproof wax Emulsion 5-10%, photoinitiator 3-7%, 4-8%, water 3-6%, non-reactive solvent 15-30%, the additives include polymerization inhibitor, defoamer, slip agent and film-forming aids. The defoamer is a mixture of foam-breaking polysiloxane, hydrophobic particles and polyethylene glycol, and the solid content of the mixture is 95-100%. The slip agent is an aqueous dispersion of ultra-high molecular weight polytetramethylsiloxane. The film-forming aid is dodecyl alcohol ester or propylene glycol methyl ether. The polymerization inhibitor includes any one of hydroquinone and arylamine. Described non-reactive solvent comprises any in ethyl acetate, chlorobenzene, toluene, xylene, acetone, methyl ethyl k...

Abstract

The invention discloses a formula of a protective layer for a printed matter. The formula is characterized in that each group of formula compositions comprises the following components: 40-60% of room-temperature cross-linked polyacrylate emulsion, 2-7% of styrene-acrylate resin liquid, 5-10% of waterproof wax emulsion, 3-7% of a photoinitiator, 4-8% of auxiliary agents, 3-6% of water, and 15-30%of a non-reactive solvent, wherein the auxiliary agents comprise a polymerization inhibitor, a defoaming agent, a slip agent and film forming auxiliary agent. The protective layer prepared according to the formula provided by the invention is suitable for various printed matters, can realize corrosion resistance, abrasion resistance and oxidation resistance of the surfaces of the printed matters,and effectively improve the luster of the surfaces of the printed matters.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a protective layer formulation for printed matter. Background technique [0002] In order to further protect the printed matter, it is often necessary to coat the printed matter with a protective layer after printing. However, the protective layer currently on the market is still insufficient in terms of gloss, anti-corrosion, wear resistance, and oxidation resistance. Satisfy the needs of customers well, and the present invention aims to solve this technical problem. Contents of the invention [0003] In view of the deficiencies in the background technology, the technical problem to be solved by the present invention is to provide a protective layer formulation that can be applied to various types of printed matter, can achieve anti-corrosion, wear-resistant and anti-oxidation on the surface of printed matter, and effectively improve the surface gloss of printed matter. [0004] For ...
