Quick-drying type primer-topcoat coating

Abstract

The invention provides a quick-drying type primer-topcoat coating and relates to the technical field of chemical coating preparation. The quick-drying type primer-topcoat coating is prepared from the following raw materials: 60-80 parts of water-based acrylic resin, 20-30 parts of amino resin, 6-8 parts of coloring pigment, 10-20 parts of a filler, 8-10 parts of a de-foaming agent, 6-8 parts of a leveling agent, 120-130 parts of de-ionized water, 6-8 parts of nanometer titanium dioxide, 5-7 parts of maleic anhydride, 8-10 parts of ethanol and 15-25 parts of curing powder. The quick-drying type primer-topcoat coating provided by the invention has the benefits that the technological process is brief, the raw material ratio is reasonable, the water-based acrylic resin and the amino resin are adopted as main materials and work together with other auxiliaries during use to obtain the quick-drying type coating, the curing speed is higher, the coating can be completely cured in 6-8 minutes at the temperature of 80-90 DEG C after being sprayed, quickness and high efficiency are realized, and the popularization and the use are convenient.

Description

technical field [0001] The invention relates to the technical field of chemical paint preparation, in particular to a quick-drying bottom-surface-in-one paint. Background technique [0002] Most of the existing domestic anti-corrosion coating systems use primers, intermediate paints, top coats or composite anti-corrosion coating systems of primers and top coats. The main function of the primer is to lay a good foundation on the substrate, which has good adhesion to the substrate and has anti-rust performance; the main function of the intermediate paint is to increase the film thickness, so as to play a more effective shielding effect, and to make the The surface is smooth, which is conducive to topcoat coating; the main function of the topcoat is to prevent harmful corrosive media in the external environment, such as oxygen, water vapor, sulfur dioxide and chemical atmosphere, and it is also beautiful and decorative. However, these two composite anti-corrosion coating syste...

Problems solved by technology

However, these two composite anti-corrosion coating systems have a long construction period, complicated operation procedures, and high cost. At the same time, it is also necessary to consider the compatibility of each coating to prevent poor inter-layer bonding and poor compatibility, resulting in the entire coating. Layer system quality drops

[0003] Therefore, the combination of base and surface paint has been widely used in recent years. The combination of primer and topcoat has no primer, is convenient for construction, and does not have cumbersome operation steps. However, the combination of bottom and surface is used in daily fields. After construction, the drying speed is slow, and the harmful gas generated during curing takes a long time. Therefore, how to make the paint with the bottom surface integrated after construction and dry quickly is the most important research topic at present.
