A kind of water-based paint and its preparation and use method

Abstract

The invention provides a water-based paint and preparation and application methods thereof. The water-based paint is mainly prepared from a specific amount of water-based polyurethane resin, water-based organosilicon-modified polyurethane dispersion, organic silicon resin, water-based fluorocarbon resin, water-based organosilicon-modified acrylate, polyethylene wax slurry and water-based acrylic resin. The water-based paint is moderate in viscosity, uniform in raw material dispersion, good in physical property, good in film-forming property, leveling property, heat stability and glossiness, good in anti-ultraviolet property, antifouling property and wear-resisting property, and high in operability, can be used in a simple wiping manner, and is free of waste, free of pollution, safe and environment-friendly. The preparation method of the water-based paint is simple and suitable for large-scale production. The water-based paint can be used in manners, such as wiping, brush coating, roller coating and spray coating, especially can be used in a wiping manner, and is time-saving and labor-saving.

Description

technical field [0001] The invention relates to the technical field of modified paint, in particular to a water-based paint and its preparation and use method. Background technique [0002] As a paint substitute product, water-based paint has the following advantages: [0003] Using water as a solvent saves a lot of resources; eliminates the risk of fire during construction; reduces air pollution; only uses a small amount of low-toxic alcohol ether organic solvents to improve the working environment. Water-based paint has good adaptability to the surface of the material, and the coating has strong adhesion. The coating tools can be cleaned with water, which greatly reduces the consumption of cleaning solvents and effectively reduces the damage to construction personnel. [0004] In the related art, the water-based paint has poor leveling property and quick drying, so it can only be applied by spraying and other energy-intensive coating methods. If spraying is used, its ut...

AI Technical Summary

Problems solved by technology

[0004] In related technologies, water-based paints have poor leveling and fast drying, so they can only be applied by spraying and other energy-intensive coating methods.

If spraying is used, its utilization rate will be very low, only 30%-40% of the paint can be attached to the surface of the target object, and a large amount of paint will enter the air, wasting a lot of paint raw materials and water, and bringing Pollution

In addition, the way of spraying is also easy to produce paint residue, which needs to be polished later, which will generate dust and other pollution

The cost of spraying equipment itself is relatively high, the power consumption during the construction process is large, the construction process is complicated, the labor cost is high, and the efficiency is low. The actual promotion is limited.
