Abstract

The invention belongs to the technical field of paint and particularly relates to a clear polyurethane seal primer and a preparation method thereof. The clear polyurethane seal primer is prepared from a component A and a component B, wherein based on the total mass 100% of the component A, the component A is prepared from 75%-79% by mass of an alkyd resin solution, 0.1%-0.3% by mass of a defoamer, 3%-5% by mass of polypropylene wax powder, 6%-8% by mass of xylene and 9.7%-13.9% by mass of first butyl acetate; based on the total mass 100% of the component B, the component B is prepared from 73%-75% by mass of an aromatic isocyanate adduct and 25%-27% by mass of second butyl acetate. The clear polyurethane seal primer has good seal effect and excellent filling performance simultaneously, seal performance and filling performance can be both achieved by constructing one seal primer, so that the primer construction times can be reduced, and cost of a construction process is saved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a polyurethane sealing clear primer and a preparation method thereof. Background technique [0002] The furniture paint coating process can generally be divided into open, semi-open and fully enclosed coating processes. The open process is generally applied to woods such as ash and oak with wider and deeper conduits, and nitro lacquer with poor fullness, water-based wood lacquer, and specially designed polyurethane lacquer formula are used for 1-3 constructions , to show the conduit of the wood to the greatest extent, and at the same time, the entire wood base surface needs to be evenly covered with a layer of paint to show the best effect, which not only gives the furniture a natural decorative effect, but also gives the furniture all-round protection. The fully enclosed process is to carry out multiple constructions on the base material to completely fill the cond...
