Water-based environmental protection paint specially used for container and preparation method thereof

Abstract

The invention provides water-based environmental protection paint specially used for a container, which belongs to the technical field of paint. The water-based environmental protection paint specially used for the container is prepared from, by weight, the following raw materials: 20-35 parts of water-based alkyd resin, 3-6 parts of a solvent, 1-2.5 parts of a pH regulating agent, 10-30 parts ofdeionized water, 0.3-0.4 part of a defoaming agent, 1-3 parts of a dispersant, 5-10 parts of organic bentonite, 0.1-0.5 part of a dryer, 1-2 parts of nanometer aluminum oxide, 1-3 parts of an ultraviolet ray absorbent, 0.2-0.5 part of graphene oxide, 20-30 parts of pigments and fillers, 0.5-1 part of a water-based oil resistance agent, 0.3-0.8 part of a wetting agent, and 5-10 parts of a poly(tetrafluoroethylene) solution, wherein the water-based alkyd resin is a water-soluble self-drying alkyd resin. A coating prepared by the water-based environmental protection paint specially used for the container of the invention has the characteristics of smooth surface without pinholes, oil resistance of more than 1000 h, and excellent stain resistance performance.

Description

technical field [0001] The invention relates to a special water-based environmental protection coating for containers and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] At present, my country is the largest manufacturer of containers in the world. The annual production capacity of containers in my country has reached 5.8 million TEU (standard containers), ranking first in the world; the specifications and varieties of containers produced are the first in the world. The production of containers in my country ranges from dry cargo containers to general cargo. Containers, as well as special containers and box-type transport vehicles, have more than 900 specifications and varieties, which can meet various transportation needs; the production and sales volume of containers ranks first in the world. Ten thousand TEU, (TEU is the international standard container unit). [0003] During the use of the container, it will be aff...
