Waterborne epoxy hammer paint and preparation method thereof

Abstract

The invention discloses waterborne epoxy hammer paint and a preparation method thereof. The waterborne epoxy hammer paint is prepared from a component A and a component B, wherein the component A is prepared from waterborne epoxy resin, deionized water, a co-solvent, a wetting agent, a hammering agent, a thixotropic agent, a thickening agent, a dispersing agent, silver powder, color paste and a defoaming agent; the component B is prepared from a waterborne epoxy curing agent and deionized water. The preparation method comprises the steps of adding the waterborne epoxy resin into a paint mixingtank, and then adding the dispersing agent, the wetting agent and the deionized water into the paint mixing tank; adding the co-solvent and the thixotropic agent in a high-speed stirring state, thenblending with the color paste so as to obtain the required color, and then adding the thickening agent and the silver powder; after the mixture is evenly stirred, reducing the stirring speed, and adding the hammering agent and the defoaming agent under the condition of low-speed stirring so as to obtain the component A; evenly mixing the waterborne epoxy curing agent with the deionized water to obtain the component B; evenly mixing the prepared component A and component B to obtain the waterborne epoxy hammer paint. The waterborne epoxy hammer paint prepared by the invention has the advantagesof being attractive in appearance, high in paint film hardness, good in corrosion resistance and high in glossiness.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based epoxy hammer paint and a preparation method thereof. Background technique [0002] Hammer paint is a commonly used industrial art paint. It can form a layer of paint film similar to the hammer pattern left after the hammer hits the iron sheet on the surface of the painted object, so it is called hammer paint. It can not only cover the unevenness or other defects of the substrate, but also does not have the disadvantage of easy accumulation of dust and dirt in the wrinkles of wrinkle paint, and has an excellent protective and decorative effect. Its application fields have been mainly used for decoration of metal surfaces such as instruments, meters, hardware parts, medical equipment, metal filing cabinets, safes, and security doors. [0003] At present, with the steady growth of China's economy, the pressure on the environment is also increasing, especially the smog that has...

Problems solved by technology

At present, water-based industrial paints have been successfully applied to construction machinery, baking varnishes, furniture paints and even automotive paints. However, in the field of hammer paint, the comprehensive performance of water-based paints is still difficult to meet the demand. For example, the construction performance of two-component polyurethane series is poor. , The pattern is not as beautiful as the paint, the hardness is poor, the gloss is poor, the weather resistance of the paint film is poor, especially the corrosion resistance is poor
