Problems solved by technology

[0002] At present, domestic marking paints are mainly thermoplastic solvent-based marking paints. The construction process requires special heating equipment. The construction is difficult and there are potential safety hazards. In addition, solvent-based marking paints will volatilize a large amount of VOC harmful substances during the drying process. , causing great pollution to the surrounding environment

Abstract

The invention discloses a water-based marking paint which comprises the following components in parts by weight: 300-500 parts of water-based emulsion, 15-25 parts of industrial alcohol, 5-15 parts of titanium white, 200-350 parts of coarse whiting, 5-15 parts of glass bead, 5-15 parts of film-forming assistant, 1-2 parts of defoaming agent, 0.5-1.5 parts of wetting agent, 1.0-2.5 parts of dispersant, 0.5-1.0 part of pH regulator, 0.5-1.5 parts of thickening agent and 10-20 parts of water. The water-based marking paint disclosed by the invention uses water as the dispersion medium, thus, is safe and environment-friendly, and does not need heating in the construction process; and the water-based marking paint has the characteristics of favorable wear resistance, weather resistance, rain water resistance, acid resistance, alkali resistance and the like.

Description

technical field [0001] The invention relates to a marking paint, in particular to a reflective water-based marking paint and a preparation method thereof. Background technique [0002] At present, domestic marking paints are mainly thermoplastic solvent-based marking paints. The construction process requires special heating equipment. The construction is difficult and there are safety hazards, and solvent-based marking paints will volatilize a large amount of VOC harmful substances during the drying process. , causing great pollution to the surrounding environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water-based marking paint with simple and safe construction operation and extremely low VOC content and a preparation method of the water-based marking paint. [0004] The present invention adopts following technical scheme: [0005] A water-based marking paint, comprising the following components by ...
