Problems solved by technology

The traditional painting method is to spray multiple primers on the wood surface. However, after each primer is sprayed, it needs to wait for a period of time to dry completely before polishing, and then proceed to the next painting process. Such a painting process requires consumes a lot of time and manpower
[0003] But, along with the progress of technology, researchers have all done more improvement and optimization in aspects such as the formulation and performance of two-component coatings, Chinese invention patent CN111040601A discloses a kind of water-based skin feeling two-component wood coating, in In the published patent, it is prepared by water-based polyurethane, defoamer, wetting agent, matting powder, and isocyanate. However, after the two-component coating prepared in the published patent is after-coated at one time, bubbles, Detrimental effect on subsequent topcoat application

Abstract

The invention belongs to the technical field of C09D coatings, and particularly relates to a thick-coating anti-foaming two-component coating as well as a preparation method and a construction method thereof. The invention relates to an anti-foaming double-component coating capable of being thickly coated. The preparation raw materials comprise a first component and a second component, the weight ratio of the first component to the second component is 1: (0.3-0.5); the anti-foaming double-component coating capable of being thickly coated, which is prepared by the preparation method disclosed by the invention, is mainly applied to decorative materials for furniture and home decoration, is an odorless environment-friendly coating and has convenient and rapid construction performance; according to the anti-foaming double-component coating capable of being thickly coated, the specific alkyd resin and the second filler added into the system are compounded, so that an excellent compounding synergistic effect is generated, a very remarkable contribution is provided for the anti-foaming property of the coating, the effect of post-coating can be realized in the use process of the coating, and the anti-foaming performance of the coating is improved. And internal defects are avoided, so that the performance of the paint film is prevented from being influenced.

Description

technical field [0001] The invention belongs to the technical field of CO9D coatings, and more particularly relates to thick-coating and anti-foaming two-component coatings and a preparation method and construction method thereof. Background technique [0002] With the development of my country's social economy and people's increasing demand for wood furniture, with the increase in the use of wood furniture, the traditional method of painting the surface of furniture is increasingly unable to meet people's needs. The traditional coating method is to spray multiple primers on the surface of the wood. However, after each primer is sprayed, it needs to wait for a period of drying before grinding, and then proceed to the next coating process. Such a coating process requires Consume a lot of time and manpower. [0003] However, with the advancement of technology, researchers have made more improvements and optimizations in the formulation and performance of two-component coating...
