Abstract

The invention discloses matched paint capable of realizing wet-spraying wet construction and a preparation method and a construction process of the matched paint. Acrylic resins, unsaturated polyesterresins and amino resins are selected as film forming matters in finishing coat, so that the finishing coat has excellent adhesive force and also has a primer-free function; moreover, two amino resinsof different acid values are selected to be matched with the acrylic resins and unsaturated polyester resins in varnish, so that the varnish and the finishing coat have excellent compatibility. The matched paint composed of the finishing coat and the varnish can realize the wet-spraying wet construction process while meeting properties of the film such as appearance, gloss, hardness, salt spray resistance and the like, so that the production efficiency is greatly improved, the energy consumption is reduced, and the requirements of energy conservation and emission reduction are met. The glossof the film can reach 100 (60 degrees) or higher, the hardness can reach 2H, the adhesive force reaches level 0, the weather resistance can reach 5000h or more (the thickness of the composite dry filmis 30-40 microns), the water resistance can reach 30 days, the salt spray resistance can reach 30 days, and chemical resistance, oil resistance and the like are excellent.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a matching paint capable of wet-spraying construction, a preparation method and a construction process thereof. Background technique [0002] With the improvement of people's environmental protection concept, the demand for new green and environmentally friendly coatings is increasing, and the water-based industrial coatings are getting more and more attention. Water-based paint is a new type of green and environmentally friendly paint with mostly excellent properties. Its development and use have pointed out a new way out for the paint industry. However, there are still many problems to be solved in the existing water-based coatings. For example, the construction process of water-based coatings is relatively complicated, and it needs to go through three basic steps of spraying, leveling and baking, which seriously affects the construction efficiency. Moreover, the drying proces...
