Problems solved by technology

At present, most of the furniture products have direct contact with the human body, especially the office furniture series. If the painted surface is often exposed to these pollution sources, it will directly affect the effect of the painting, and then affect the service life of the furniture.
[0003] The PU transparent topcoat in the prior art cannot effectively block the corrosion of the paint film by pollutants such as hand sweat and oil stains, and the surface of the coating film is prone to local loss of gloss, which not only affects the effect of coating, but also shortens the furniture. service life

Abstract

The present invention relates to a kind of PU transparent topcoat and its preparation method; especially to a kind of anti-stain PU matte transparent topcoat and its preparation method, the present invention is suitable for furniture coating, especially suitable for often contact with hands and other body The coating of oil-secreting and sweat-contact parts and other furniture products that come into contact with oil. The present invention achieves the above-mentioned purpose by adopting the following formula, a kind of anti-adhesion PU matte transparent finish paint, it is formulated by the weight of 1:0.5:0.4-1:0.5:0.8 by main paint, curing agent and diluent than formulated. The anti-adhesive PU matte transparent topcoat provided by the invention can not only form a special long-term dense protective film on the surface of the fully film-formed coating film after painting, but also effectively block pollution such as hand sweat and oil stains Corrosion of the paint film by substances; and has the characteristics of good adhesion to the primer and good hardness.

Description

technical field [0001] The present invention relates to a kind of PU transparent topcoat and its preparation method; especially to a kind of anti-stain PU matte transparent topcoat and its preparation method, the present invention is suitable for furniture coating, especially suitable for often contact with hands and other body The coating of oil-secreting and sweat-contact parts and other furniture products that come into contact with oil. Background technique [0002] After the surface of some furniture is painted, due to the frequent contact of the human body, marks will be left on the contact surface. This mark will make the local gloss, feel and transparency abnormal, thus affecting the overall appearance and effect of the furniture. This is because the human skin, especially the hands, secrete a large amount of oil and sweat. These substances have strong oxidizing properties and are weakly acidic in performance. After a certain amount of accumulation, these acidic subs...
