Problems solved by technology

[0003] The existing products are mainly solvent-based, and it is necessary to solve the problem of high VOC content and serious pollution in the paint. The existing water-based hammer paint products are used as topcoats and need to be equipped with epoxy primers, so the construction cost is much higher than that of solvent-based products. It affects the promotion of the product, and most of them are two-component acrylic polyurethane series, which has high cost and is not as convenient as single-component products in construction

Abstract

The invention discloses a one-component self-drying water-based hammer paint and a preparation method thereof. The one-component self-drying water-based hammer paint comprises the following componentsby mass: 60-75% of a water-based acrylic emulsion, 0.2-0.3% of a pH value regulator, 3-5% of an environmentally-friendly solvent, 0.1% of a substrate wetting agent, 0.2-0.3% of a water-based disperser, 0.3-0.4% of a defoamer, 2-3% of a non-floating aluminum paste, 0.2% of modified lithium magnesium silicate, 0.5% of bentonite, 1% of a water-based flash rust inhibitor, 1-3 % of a water-based thickener, 0.5-0.8% of a hammer finish additive, 5-8% of industrial alcohol and 3-6% of water-based color paste. The one-component self-drying water-based hammer paint of the invention has the advantages of environmental protection, equivalent cost, simple construction, no needfor a diluent, no defects such as prickly heat and pinholes, and fast drying.

Description

technical field [0001] The invention relates to the field of water-based paint, in particular to a one-component self-drying water-based hammer paint and a preparation method thereof. Background technique [0002] One-component hammer paint is a commonly used industrial art paint. It can form a layer of paint film similar to the hammer pattern left after a hammer hits an iron sheet on the surface of the painted object, so it is called hammer. Pattern 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 wrinkled 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. At present, with the steady growth of China's economy, the pressure on the environment is als...
