Problems solved by technology

Although the water-based epoxy floor paint prepared by this method overcomes the agglomeration phenomenon of graphene, making the paint film withstand the erosion of a certain concentration of acid-base medium, but due to not considering the relationship between graphene and water-based epoxy floor paint Interface, in long-term use, its stability is poor, and it cannot withstand the erosion of acid and alkali for a long time

Abstract

The invention discloses a preparation method of waterborne epoxy floor paint, and belongs to the technical field of floor paint processing and preparation, wherein the preparation method comprises thefollowing steps: S1, preparing a modified inorganic filler; S2, weighing raw materials; and S3, preparing a finished product. The invention provides the preparation method of the waterborne epoxy floor paint. The special modified inorganic filler is added in the preparation of the waterborne epoxy floor paint; the compatibility of the modified inorganic filler and the matrix component is excellent; the acid and alkali resistance, the oil resistance, the water resistance and the wear resistance of the finally prepared waterborne epoxy floor paint are effectively improved, so that a paint filmis corroded by an acid and alkali medium with a certain concentration, the acid and alkali resistance time is prolonged, the performance stability is good, the defect that the hardness of the paint film is too low is overcome, the hardness can reach 4H, and the comprehensive performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of floor paint processing and preparation, and particularly relates to a preparation method of a water-based epoxy floor paint. Background technique [0002] Epoxy floor paint (or epoxy paint) coating is a ground and wall coating method that has risen rapidly with the advancement of industrial technology and the improvement of people's living standards. At present, epoxy floor paint has become the coating industry. One of the strongest developing lacquers in China. Epoxy floor paint is known for its many advantages, such as the coating surface is smooth and clean, and can be in a matte state of diffuse reflection; good integrity, less or complete, no gaps, so it is not easy to accumulate dust and bacteria , easy to clean; high surface hardness, with a certain degree of wear resistance and compressive strength; rich colors, bright, decorative; good waterproof and anti-permeability, which can avoid polluting ...
