Problems solved by technology

The anti-slip epoxy floor generally uses aggregates such as coarse-grained quartz sand, and then roll-coats a layer of epoxy topcoat on the aggregate layer. The wear of the tires is relatively large, and there will be a large friction sound when the car is running, and this coating is difficult to clean
In addition, because the outdoor durability of epoxy floor coating is poor, it is easy to yellow and powder, so epoxy floor coating is only suitable for indoor use
At present, the polyurethane floor coating used in outdoor parking lots contains a large amount of organic solvents, which will release a large amount of volatile organic compounds during the construction process, which is poor in environmental protection and is not conducive to the health of construction workers.

Abstract

The invention belongs to the technical field of floor paint, and particularly relates to composite floor paint, a preparation method thereof and a using method thereof. The composite floor paint comprises an epoxy primer, leveling blanket paint and surface coating paint. The surface coating paint comprises solvent-free epoxy self-leveling surface paint and polyurethane finish paint. When construction is performed, the epoxy primer, the leveling blanket paint, the solvent-free epoxy self-leveling surface paint and the polyurethane finish paint are painted in order on a pretreated floor. The composite floor paint has a low content of volatile organic compounds, and is suitable for indoor or outdoor floor decorative painting. A composite floor manufactured by the composite floor paint is antiskid, wear resistant, acid and alkali resistant and weather-proof, and is high in hardness, high in bonding strength with a floor base surface.

Description

technical field [0001] The invention relates to the technical field of floor coatings, in particular to a composite floor coating and a preparation method and application method thereof. Background technique [0002] Floor coatings are mainly used in building floor decoration in industrial plants, warehouses, parking lots, shopping malls, sports fields, schools, hospitals and offices. Floor coatings can be divided into epoxy floor coatings, polyurethane floor coatings, vinyl floor coatings, and acrylic floor coatings. [0003] Indoor parking lots often use epoxy floor coatings to coat the building ground of the parking lot, while outdoor parking lots usually use polyurethane coatings to coat the building ground of the parking lot. The floor coating of the driving area and the parking area of ​​the indoor parking lot are different. The parking area is a smooth epoxy floor coating, and the driving area is a non-slip epoxy floor coating. The smooth epoxy floor coating is easy...
