Abstract

The invention provides a water-based single-component white finish applied to a PVC (polyvinyl chloride) substrate and a preparation method of the water-based single-component white finish. The water-based paint is prepared from the following raw materials: water-based resin, a dipropylene glycol ether compound, a wetting agent, an organic silicon defoaming agent, white paste, a delustering agent, a flatting agent, a thickening agent and deionized water. The prepared finish paint has good wear resistance and scratch resistance, can be used as finish paint of a PVC base material, has excellent adhesion to both a PVC base material which is not subjected to surface treatment and a PVC base material which is subjected to surface treatment, and can omit a treatment procedure of wiping a solvent on the surface of the PVC base material in a PVC base material finish paint spraying process in a furniture factory; and meanwhile, the factory cost is saved, and the delivery efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of C09D133 / 00, and particularly relates to a water-based single-component white topcoat applied to a PVC substrate and a preparation method thereof. Background technique [0002] The water-based one-component topcoat has the advantages of energy saving, environmental protection and simple use process, and has been widely welcomed in the market in recent years. However, the common water-based one-component topcoats on the market are easy to scratch and scratch the paint film, which brings great difficulties to packaging, transportation and daily use. Chinese patent CN107312412A discloses a one-component matte finish, which has good water resistance, stain resistance and mechanical properties, and can be widely used in the surface coating of wood furniture and wood substrates. In addition to wood, furniture is made of metal materials, plastic materials, etc., such as PVC materials. However, at present, for t...
