Abstract

Provided is an inorganic nano particle modified coating polyurea road marking composite coating and a preparation method thereof. The inorganic nano particle modified coating polyurea road marking composite coating is composed of an A component and a B component, wherein the formula of the A component is that 10-35 parts of thermoset resin, 10-35 parts of thermoplasticity resin; 20-70 parts of polyaspartic acid ester; 0.1-1part of inorganic nano materials, 5-100 parts of pigment; 0.15-0.3 parts of dispersing agent; 0.15-0.3 assistant; and diluent margin; so that total parts are 100; the formula of the B component is that 80-90 parts of aliphatic series polyisocyanates; 10-20 parts of diluent and so that total parts are 100; the A component and the B component are mixed with a size ratio of 1-4: 1 in the using process; the preparation method is that the A component and the B component are respectively prepared, and are mixed based on the ratio and use a coating machine to coat in the using process. The road marking composite coating of the inorganic nano particle modified coating polyurea road marking composite coating effectively overcomes a plurality of defects of a traditional road marking composite coating, thereby possessing good adhesive force, wear resistant performance and anti-pollution performance, so that the construction performance and the mechanics performance of the inorganic nano particle modified coating polyurea road marking composite coating are excellent.

Description

technical field [0001] The invention relates to an inorganic nano particle modified road marking composite paint for spraying construction and a preparation method thereof. Background technique [0002] Traditional solvent-based, hot-melt or water-based road marking coatings have poor adhesion to the road surface after construction, and are easy to fall off from the road surface, and the paint film is easy to stick to dust, mud, oil and other dirt, making the markings Lines become unclear, and the overall appearance effect is poor, affecting road traffic safety. In addition, the traditional road marking paint is made of thermoplastic resin, and the formed paint film has poor mechanical properties, low strength, poor wear resistance, short service life, poor affinity with reflective glass beads, and the reflective glass beads sprinkled on the surface are easily damaged. At the same time, the rough surface formed after film formation reduces the anti-fouling performance of th...
