Abstract

The invention relates to water-based industrial paint, in particular to high-hardness single-component water-based paint and a preparation method thereof. The high-hardness single-component water-based paint is prepared from water-based resin, water-based emulsion, a drier, conventional auxiliaries, a neutralizer, a pigment, a filler, deionized water, a thickener and a solvent, the high-hardness single-component water-based paint is prepared by mixing the proper modified acrylic resin and the water-based acrylic emulsion with the high TG value and matching the mixture with the proper pigment,filler and assistant, so that the film forming property is ensured, the film forming speed can be improved, and the drying speed is increased; the prepared finished paint has the characteristics of high hardness improvement speed, good salt spray resistance, no harm to a human body, good environmental protection performance and the like, and the hardness can be improved to H level; the preparationprocess is simple, easy to operate and low in production cost, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a water-based industrial coating, in particular to a water-based one-component coating with high hardness, strong adhesion and good salt spray resistance of the paint film. Background technique [0002] The existing methods for preparing one-component paints often use thinners as diluents. The paints prepared by this method often contain toxic and harmful substances such as formaldehyde, toluene, and xylene, which seriously pollute the atmosphere and are not conducive to the protection of personal life and property safety. , At the same time, the hardness of traditional water-based one-component coatings is low, the highest can reach HB, and the paint film has poor salt spray resistance and other characteristics. [0003] Therefore, there is an urgent need to develop a high-hardness one-component water-based coating, which is harmless to the human body, and has high hardness and good salt spray resistance.
