Waterborne dipping paint for engineering tracks and preparation method for waterborne dipping paint

Abstract

The invention discloses a waterborne dipping paint for engineering tracks, and a preparation method for the waterborne dipping paint, and relates to engineering track protective paints. The invention provides a waterborne dipping paint for the engineering tracks, and the volatile organic compounds (VOC) are less than 20g / L. The paint belongs to an environment-friendly coating, has low VOC content and small odor, is noninflammable and inexplosive, solves the problems that a solvent-based dipping paint and a water soluble dipping paint has harm to environment and human health, has the advantages of stable bath solution, convenience in construction, wide application range and suitability for large-scale industrial continuous production, solves various problems of sagging, edge shrinkage, bottom leakage, blur and the like of the dipping paint, and accords with the construction condition of low temperature drying or air drying. In the waterborne dipping paint for the engineering tracks, waterborne acrylic emulsion is taken as a base material, propylene glycol, a pH regulator, a dispersing agent, a wetting agent, a defoaming agent I, a defoaming agent II, an antiseptic, a film forming aid, a flashrust inhibitor, a base material wetting agent and a thickening agent are taken as aids, and carbon black and rutile type titanium dioxide are taken as pigments and fillers.

Description

technical field [0001] The invention belongs to the field of metal protection, and in particular relates to a paint for engineering track surface protection and a preparation method thereof. Background technique [0002] At present, most of the engineering crawler coatings in my country still use solvent-based spray (or dip) paint. The spraying process occupies a large production area, the production efficiency is low, and it is difficult to form a balanced production. The utilization rate of raw materials is low, the pollution is large, and the labor intensity of the operator is high. In addition, due to the complex structure and shape of the track, many parts are prone to spray leakage, which is serious. Affected the coating quality of the track. Although the utilization rate of coatings by dip coating is high, solvent-based dip coatings will release a large amount of VOC (volatile organic compounds, volatile organic compounds) during coating, causing air pollution, and s...

Problems solved by technology

The spraying process occupies a large production area, the production efficiency is low, and it is difficult to form a balanced production. The utilization rate of raw materials is low, the pollution is large, and the labor intensity of the operator is high. In addition, due to the complex structure and shape of the track, many parts are prone to spray leakage, which is serious. Affected the coating quality of the track

Although the utilization rate of coatings by dip coating is high, solvent-based dip coatings will release a large amount of VOC (volatile organic compounds, volatile organic compounds) during coating, causing air pollution, and solvent-based coatings are flammable and explosive. , there is always a fire hazard

There are also a small number of manufacturers using water-soluble dip-coating paint. Although water-soluble dip-coating paint belongs to the category of water-based coatings, water-soluble dip-coating paint requires a large amount of solvent dilution. In practical applications, the solvent consumption is extremely large, as high as 25%-30% , poor stability of the bath solution, serious sagging, edge shrinkage, bottom leakage, blooming and other paint film defects in the paint film, requiring a large number of repairs, emitting a large amount of harmful gases, polluting the environment and harming the health of employees
