Embodiment Construction

[0017] Below in conjunction with specific embodiment, the present invention will be further elaborated and described:

[0018] An anti-sticking and anti-scribbling coating, according to the mass ratio, includes 60-65 parts of water-based polyurethane of Bayer company AXP2695; 10-20 parts of DuPont R706 pigment and filler; 2 to 5 parts of acrylate; 1 to 3 parts of 650 type dispersant of Digao company; 0.5 to 1 part of leveling agent of BYK3550 type of BYK company; 0.2 to 0.5 part of defoamer of BYK035 type of BYK company; The wetting agent of the WET270 model is 0.5 to 1 part; the curing agent of the Bayer N3790BA model is 0.1 to 0.3 parts; the water is 8 to 15 parts.

[0019] Bayer's AXP2695 waterborne polyurethane has a high degree of cross-linking, so it has excellent chemical resistance and high hardness. If it is not completely, there will be no coating defects such as shrinkage and blooming, and the adhesion between the coatings is good. Although the surface tension of t...

Abstract

The invention discloses an anti-sticking and anti-scribbling coating which comprises the following components in parts by mass: 60-65 parts of waterborne polyurethane; 10-20 parts of pigment and filler; 2-5 parts of hydroxyl-containing organic silicon modified polyacrylate; 1-3 parts of a dispersant; 0.5-1 part of a leveling agent; 0.2-0.5 part of a defoaming agent; 0.5-1 part of a wetting agent; 0.1-0.3 part of a curing agent; and 8-15 parts of water. The anti-sticking and anti-scribbling coating disclosed by the invention has the characteristics of lasting anti-scribbling and anti-sticking properties, and is simple in proportioning.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an anti-sticking and anti-scribing paint. Background technique [0002] Graffiti is a form of cultural expression, a reflection of life, views and perspectives on life. However, graffiti scribbled in public places has seriously affected the cityscape and damaged the image of the region.
