Abstract

The invention discloses transparent polyurethane paint for dyed veneer and a preparation method of the transparent polyurethane paint. The raw materials of the transparent polyurethane paint include,in parts by weight, 30-45 parts of polyurethane resin, 10-20 parts of xylene, 10-20 parts of butyl acetate, 4-6 parts of cyclohexanone, 4-8 parts of a cyanoacetoxy compound, 4-6 parts of a polyvinyl acetate emulsion, 10-15 parts of 107 glue, 4-5 parts of a whitening agent, 2-6 parts of a flocculant and 6-10 parts of clear water. The invention relates to the technical field of polyurethane paint. According to the transparent polyurethane paint for dyed veneer and the preparation method of the transparent polyurethane paint, the produced transparent polyurethane paint has three characteristics,a high condensation speed, more convenient use and a wider application range, use of the transparent polyurethane paint is not restricted, application is facilitated, and the problems are solved thatadhesion viscosity, adhesion strength and drying speed of existing transparent polyurethane paint cannot be ensured at the same time due to limitation of materials, and it is ensured that only one ofthe three indexes can be met.

Description

technical field [0001] The invention relates to the technical field of polyurethane paint, in particular to a transparent polyurethane paint for dyeing veneer and a preparation method thereof. Background technique [0002] Polyurethane paint is polyurethane paint. It has strong paint film, full luster, strong adhesion, water resistance, wear resistance and corrosion resistance. It is widely used in high-grade wooden furniture and can also be used on metal surfaces. Its shortcomings mainly include problems such as foaming when it is wet, and powdering of the paint film. Like polyester paint, it also has the problem of yellowing. The varnish variety of polyurethane paint is called polyurethane varnish. Polyurethane coating is a relatively common type of coating, which can be divided into two-component polyurethane coatings and one-component polyurethane coatings. Two-component polyurethane coatings are generally composed of isocyanate prepolymers (also known as low-molecular...
