Preparation method for aqueous floor coating

Abstract

The invention relates to a preparation method for an aqueous floor coating. The aqueous floor coating is prepared from the components in parts by weight of 80-100 parts of a component A and 40-50 parts of a component B, wherein the component A is prepared from the following components in parts by weight of 30-35 parts of water, 15-25 parts of an aqueous epoxy curing agent, 1-3 parts of an adjuvant, 0.1-0.7 part of an antifoaming agent, 10-15 parts of quartz powder, 5-10 parts of precipitated barium sulfate and 0.2-0.8 part of a thickening agent; the component B is prepared from the following raw materials in parts by weight of 15-18 parts of liquid epoxy resin, 1-3 parts of a reactive diluent and 3-4 parts of an environment-friendly type organic solvent. The preparation method comprises the following steps: dispersing the raw materials of the component A at a high speed of 1000-2000rpm for 5-10 minutes; grinding the raw materials of the component A until the fitness is 10-30 microns; mixing the raw materials with the residual water at a speed of 500-800rpm for 3-10 minutes, so as to obtain the component A; mixing the raw materials of the component B at a speed of 200-600rpm for 10-20 minutes, so as to obtain the component B; mixing the component A and the component B at a ratio ranging from 1:1 to 1:3, so as to obtain the aqueous floor coating. The aqueous floor coating can avoid the environment pollution and damage on human health, has strong air permeability, is applicable to wet basal plane, and meets the requirements on the environmental friendliness.

Description

technical field [0001] The invention relates to a method for preparing a water-based floor coating, in particular to a water-based floor coating that can avoid environmental pollution, avoid damage to personal health, has strong air permeability, is suitable for use on wet base surfaces, and meets environmental protection requirements, and belongs to coatings material field. Background technique [0002] Modern industry has put forward more and more stringent requirements on the floor. For example, food, medicine and other industries require the floor to be dust-free, free of harmful volatiles, and clean and dust-free; the machinery industry requires strong mechanical shock resistance, wear resistance, and It has been rolled by forklifts and other vehicles for a long time, and it is easy to repair even if it is partially damaged; the ground of industrial workshops such as machine tools and instruments is often corroded and leaked by various oils, which is difficult to comple...
