Problems solved by technology

[0003] Although water-based coatings have the advantages of being non-toxic, non-polluting, non-flammable and non-explosive, each type of coating has different defects. Before discovering suitable new materials, researchers must optimize the main components of various coatings and strengthen the synergy of each component, so as to make up for the defects of different water-based coatings

Abstract

The invention relates to the technical field of water-based paint, and particularly discloses a preparation method of high-wear-resistance and high-sewage-resistance water-based paint which comprises epoxy resin, inorganic filler, a silane coupling agent, pigment, a flatting agent, a defoaming agent, a curing agent, a paint additive and water. According to the technical scheme, by utilizing the synergistic effect of the raw materials, the wear resistance and pollution resistance of the epoxy resin water-based paint are improved on the premise of effectively ensuring high adhesive force and high chemical stability of the epoxy resin water-based paint. The invention also provides a preparation method of the high-wear-resistance and high-sewage-resistance waterborne coating. The preparation method comprises the following steps: adding water into the coating additive, and grinding to obtain a coating additive; blending the inorganic filler, the pigment, the epoxy resin and the residual water to obtain a mixture; and blending the coating additive and the mixture, adding the rest raw materials, and uniformly mixing to obtain the coating. The preparation method is simple, the preparation condition is mild, and the prepared water-based paint can be used for protecting various buildings and walls and has the effects of high wear resistance and high pollution resistance.

Description

technical field [0001] The application relates to the technical field of water-based coatings, more specifically, it relates to a coating with high wear resistance and high sewage resistance and a preparation method thereof. Background technique [0002] With the increasing awareness of environmental protection, countries around the world have successively formulated the limit standards and regulations for 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 paint has the characteristics of green, energy saving, safety and convenient function, and has been developed rapidly in all countries in the world. Water-based paint (also known as water-based paint) is a purely environmentally friendly product diluted with wat...
