Problems solved by technology

Although there are also a small amount of water-based UV floor paints on the market, because the viscosity of water-based UV resins is much lower than that of traditional UV resins, it is difficult for a single rubber roller to apply more than 10g / ㎡ during roller coating. Affect the overall coating effect and wear resistance; if the coating amount is increased simply from the perspective of increasing the viscosity of the product, it will seriously affect the performance of paint film leveling, cycle defoaming, etc., resulting in poor workability, serious roll marks, and poor coating effect. Inferior ills

Abstract

The invention relates to the technical field of paints, particularly to a high-wear-resistance waterborne UV floor paint and a preparation method thereof. The high-wear-resistance waterborne UV floorpaint is composed of, by weight part, 67-80 parts of waterborne UV polyurethane dispersion, 3-5 parts of waterborne alkali-soluble acrylic emulsion, 0.4-0.8 parts of defoamer, 0.3-0.6 part of wettingagent, 0-2 parts of solubilizer, 0.1-0.2 part of neutralizer, 0.1-0.5 part of in-tank bactericide, 0.2-1 part of rheologic additives, 0.5-2 parts of matting powder, 9-22 parts of deionized water and 1-3 parts of photoinitiator. Compared with the prior art, the h high-wear-resistance waterborne UV floor paint can meet floor painting requirements and achieve high wearing resistance, specifically, can firstly meet the requirements on floor painting roller construction and UV curing, and above all, by matching different types of resins, improves product viscosity without affecting paint film performance and increases single-roller coating capacity to achieve final painting effects.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a high wear-resistant water-based UV floor paint and a preparation method thereof. Background technique [0002] In the field of wood floor coatings, most of the coating systems currently used in my country are ultraviolet curing (UV) paint and solvent-based polyurethane (PU) paint. Although there are a small amount of water-based UV floor paint on the market, the viscosity of water-based UV resin itself is much lower than that of traditional UV resin. It is difficult for the coating amount of single rubber roller to exceed 10g / ㎡ during roller coating. Affect the overall coating effect and wear resistance; if the amount of coating is increased simply from the perspective of increasing the product viscosity, it will seriously affect the film leveling and circulating defoaming properties, resulting in poor workability, serious roll marks, and coating effects Bad ills.
