Abstract

The invention provides non-yellowing high-bonding-force environment-friendly marking paint. The non-yellowing high-bonding-force environment-friendly marking paint comprises a component A and a component B in a mass ratio of (3-8): 1, wherein the component A comprises the following components in parts by weight: 20-40 parts of a base material, 20-40 parts of titanium dioxide, 0.2-1 part of a dispersing agent, 0.01-0.5 part of a catalyst and 20-40 parts of a solvent; and the component B is 10-30 parts of a curing agent. The non-yellowing environment-friendly marking paint is non-yellowing, and does not fade quickly as time goes on or rain erosion occurs; the product has excellent bonding force and is suitable for various substrates; and the solvent is an environment-friendly solvent, so that the harm to the body is reduced.

Description

technical field

[0001] The invention relates to the technical field of marking paint for sports grounds, in particular to a non-yellowing, high-adhesive, environmentally friendly marking paint. Background technique

[0002] The special marking paint for sports field is exposed to the sun, rain, wind, snow and freezing, and is subjected to the impact and wear of the soles. As time goes by, its white marking lines will fade or turn yellow quickly. If the resin and solvent system are not selected properly or are viscous The degree of control is not in place, and there are problems such as biting the bottom and burrs.

[0003] At present, most of the commonly used marking paints are based on thermoplastic acrylic resin, and are composed of pigments, fillers, additives, and solvents. Most of its solvents are toxic solvents such as xylene. In addition, some marking paints will show relatively large differences in the bonding effect to various substrates, among which the self-bon...

Examples

Embodiment 1

[0022] A non-yellowing, high-adhesion environmental-friendly marking paint, comprising A component and B component with a mass ratio of 5:1;
