Abstract

The invention relates to waterborne environment-friendly paint and a preparation method thereof, and belongs to the field of waterborne paint. The waterborne environment-friendly paint is formed by adopting polyurethane modified acrylic latex as a main raw material, adding alkylate modified gas phase method white carbon black, a dispersing agent, a flatting agent and a defoaming agent and dispersing them in water, and has the excellent tenacity, abrasion resistance, acid resistance and hardness. The adopted alkylate modified gas phase method white carbon black has the thickening and reinforcing effects, and is good in dispersibility. The adopted waterborne amine curing agent has the functions of an emulsifier and a curing agent, and can be mixed with other components to obtain the stable waterborne paint system. The waterborne environment-friendly paint obviously lower VOC volatilization, and transition to the environment-friendly paint from a traditional solvent type paint is achieved, in accordance with the environment-friendly development trend. The preparation method is simple, feasible and good in stability and repeatability and easily achieves industrial production.

Description

technical field [0001] The invention relates to a preparation method of water-based paint, in particular to a water-based environmental protection paint and a preparation method thereof, belonging to the field of water-based paint. Background technique [0002] Paint refers to the resin paint used on wooden furniture, which is divided into two types: water-soluble and oil-soluble. With the continuous progress of society, environmental protection has attracted more and more attention from the world, and people's awareness of environmental protection has also been continuously strengthened. Due to global warming and the destruction of the ozone layer, worldwide industrial environmental protection requirements are getting higher and higher. There will be a large amount of volatile organic solvents in the construction process of oil-soluble paint, which will be discharged into the atmosphere during use, which not only damages the environment and endangers people's health, but a...
