Novel vacuum ultraviolet coating material

Abstract

The invention discloses a novel vacuum ultraviolet coating material which is prepared from the following raw materials in parts by weight: 1.5-3 parts of toluene, 3.2-5.5 parts of organic sulfonic acid compound, 1.5-2 parts of aluminum acetylacetonate, 8.5-10 parts of tripropylene glycol diacrylate, 2.5-3.4 parts of thickener, 2.3-3.5 parts of epoxy resin, 4.5-7 parts of water, 3.4-5.6 parts of hexyl diisocyanate tripolymer and 0.07-0.12 part of preservative. The formula is relatively environment-friendly, optimizes the tripropylene glycol diacrylate and epoxy resin diluting monomer and enhances the adhesion property for the low-surface-tension substrate, so that the new developed product has higher heat resistance and favorable weather resistance and is applicable to multiple substrates. The ultraviolet resistance and stability of the paint are improved, the heat resistance, adhesive force and weather resistance are enhanced, the production cost is lowered, and the coating material is convenient for popularization.

Description

technical field [0001] The invention relates to a coating, in particular to a novel vacuum ultraviolet coating material, which belongs to the field of coatings. Background technique [0002] At present, the ultraviolet vacuum coating coating technology uses polyurethane acrylate as the main resin of the primer formula. Its function is mainly to provide good flexibility and certain adhesion of the cured film. Hardness, fast curing performance and good adhesion performance, but its high brittleness limits its dosage in the formula, so its dosage should not be too high; It is impossible to completely convert, so the amount of monofunctional reactive diluent in the formula should not be too high, which will cause the paint to be too viscous and inconvenient to use. Generally speaking, the existing vacuum-coated UV-curable coatings generally have disadvantages such as low heat resistance, poor adhesion and poor weather resistance.
