Abstract
The invention provides a double curing coating applied to substrates with difficulty in coating and a preparation method thereof. The double curing coating comprises 10-15 of tri(2-hydroxyethyl) isocyanurate diacrylate, 10-15 of pentaerythritol triacrylate, 15-20 of hexamethylene diisocyanate, 20-30 of acrylic polyol, 5-7 of photoinitiators, 0.2-0.5 of UV absorber, 2-3.5 of hindered amine light stabilizers, 0.2-1 of auxiliary flow agent and 20-30 of methyl ethyl ketone. The invention has the advantages of strong adhesion to various metals and composite materials and low VOC discharge.
Description
Technical field
The present invention relates to a kind of double curing coating that is applied to difficult coated substrate, it is suitable for ferrous metal (iron, steel and alloy thereof), non-ferrous metal (aluminium, zinc, magnesium and alloy thereof), matrix material (carbon fibre, glass) the upward coating and the preparation method of use.
Background technology
In order to reduce the topsoil that causes by the volatile solvent of emitting in the coating process, general requirement is tried not with an organic solvent, but, the organic solvent that does not use flowability and levelling property to coating that huge contribution is arranged, often be difficult to obtain high quality, the coating of high gloss, except the flawless outward appearance in needs surface, these coatings also need good endurance and are easy to apply.It is infeasible that the thermosetting acrylic resin of the thermofixation of routine is used for double curing coating, because solvent must during curing be removed from coating.In order to alleviate this problem, developed photo curable coating, it has reduced or has eliminated demand to solvent.But the film flexibility of photocuring can be lower, and sticking power is difficult to be applied to various ground.Based on this, developed double curing coating.The sticking power problem that this coating has solved on various metals and matrix material reaches very low VOC discharging.
