Abstract
The invention discloses an electron beam radiation curing coating for metal heavy anti-corrosion. The coating is prepared from, by mass, 50%-80% of oligomer, 0.1-0.5% of reactive diluent, 1-10% of functional filler, 5-20% of antirust dyestuff and 5-15% of auxiliary filler, and the total mass percentage of the components is 100%. The curing coating for metal heavy anti-corrosion is cured by electron beam radiation, has the advantages of high efficiency and energy conservation, environment friendship and convenient operation, cured depth of the coating is high, thickness is big, and the adhesive force between the coating and the substrate is strong. A conductive carbon material is doped in the curable coating, thus the problem of metal heavy anti-corrosion is solved while electron beam energy absorption is avoided, and it is guaranteed that cured efficiency is not affected. The electron beam radiation curing coating for metal heavy anti-corrosion has excellent wear-resistance and corrosion-resistance, can be applied to the field of metal heavy anti-corrosion anti-corrosion, and is particularly applicable to the field of maritime work heavy anti-corrosion.
Description
technical field [0001] The invention belongs to the technical field of radiation-cured coatings, in particular to an electron beam radiation-cured coating for metal heavy-duty anticorrosion. Background technique [0002] At present, with the gradual improvement of people's awareness of environmental protection, light-curing coatings are widely used as a new generation of environmentally friendly coatings. Ultraviolet (UV) light-curing coating is to cure the resin by UV light irradiation. The system does not contain volatile organic compounds (VOC), and the curing speed is fast and the efficiency is high. However, UV energy consumption is large, and there is a radiation "blind zone" for workpieces with complex shapes, which cannot be effectively cured, and the curing thickness of UV coatings is limited to 20-40 μm, and the deep curing is not complete. The adhesion of the material is not strong, and the anti-corrosion and mechanical properties are reduced. At present, it can ...
