Abstract

The invention discloses environment-friendly water-borne paint, which is prepared from the following weight parts of raw materials: 50-60 parts of maleimide-based polyether film-forming polymer, 5-10parts of Ti-Zn-S-O, 10-15 parts of calcium carbonate, 1-3 parts of a dispersant, 1-3 parts of a leveling agent, 1-3 parts of a defoamer and 15-25 parts of water. The invention also discloses a preparation method of the environment-friendly water-borne paint, and the preparation method comprises the following steps: mixing the raw materials in proportion evenly, and performing grinding and filtering to obtain the environment-friendly water-borne paint. The environment-friendly water-borne paint has the advantages of low production cost, high film hardness, high wear resistance, high fullness, tolerance in construction, good stability, safe use, environmental protection and good heat resistance.

Description

technical field [0001] The invention relates to the technical field of paint materials, in particular to an environmentally friendly water-based paint and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the improvement of living standards, people's pursuit of a perfect life and material has become more and more intense, and higher requirements have been put forward for the decoration of the home in life. While these home furnishing materials bring comfort to people, they also bring the threat of environmental pollution to people. Paint material is a kind of in many decoration materials, because the paint material in the prior art mostly contains poisonous and harmful substances such as methanol, thereby causes serious pollution to environment, produces great harm to human body. [0003] Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. It does not contain benz...
