Abstract

The invention discloses water-based metal antirust paint. The water-based metal antirust paint is prepared from, by mass, 35-45 parts of pigment, 8-15 parts of filler, 8-15 parts of corrosion inhibitors, 10-20 parts of deionized water, 15-25 parts of silicone acrylic emulsion, 0.1-0.2 part of a dispersing agent, 0.1-0.2 part of a flatting agent, 2-5 parts of an adhesive force promoting agent, 1-3 parts of film-forming aiding agent, 0.1-0.3 part of surfactant OP-10, 0.1-0.2 part of a defoaming agent and 0.05-0.1 part of bacteriacide. The invention further discloses a preparation method of the water-based metal antirust paint. The water-based metal antirust paint solves the problems that water-based metal antirust paint used in the current market is poor in corrosion resistance and adhesive force, slow in drying, poor in early-stage water resistance and high in cost.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based antirust coating and a preparation method thereof. Background technique [0002] With the enhancement of environmental protection awareness, countries have successively formulated the limit standards and regulations of volatile organic compounds (VOC) emissions. Solvent-based coatings are an important source of VOC, which cause great pollution to the environment and great harm to the human body. At the same time, there are safety hazards such as flammability and explosion in construction, storage, and transportation. Water-based coatings are green, energy-saving, safe, and easy to use, and are rapidly developing in countries all over the world. [0003] my country's water-based coating technology level is far behind developed countries. So far, there is no mature technology in China. Key materials such as high-performance water-based resins still rely ...
