Problems solved by technology

Solvent-based road marking paint refers to the marking paint that is constructed at room temperature and formed by solvent volatilization. This type of paint generally has a short service life, poor wear resistance and long drying time.
Hot-melt road marking paint is made of natural resin or petroleum synthetic resin as the film-forming material. It is incompatible with solvents. It is a powder block material at room temperature. It needs to be heated and melted when used. After coating, it is cooled to become a solid bonded to the road surface. The film layer has the characteristics of short drying time, good adhesion to the road surface, and no pollution to the environment. However, hot-melt coatings have disadvantages such as slow construction speed, complicated construction conditions, and difficulty in renewing or changing old lines.

Abstract

The invention provides a composition of a two-component marking coating and a preparation method thereof. The composition of the two-component marking coating comprises a component A and a component B, and the mass ratio of the component A to the component B is 3-3.5: 1. The component A is prepared from the following raw materials, by weight: 17 to 20 parts of acrylic resin, 15 to 18 parts of polycaprolactone polyol,1 to 1.8 parts of nano-zinc oxide loaded graphene oxide, 10 to 15 parts of modified hollow glass beads, 5 to 8 parts of titanium dioxide, 0.3 to 0.6 part of a silane coupling agent, 30 to 35 parts of fillers, 0 to 1.5 parts of pigment, 0.5 to 0.8 part of a dispersing agent, 0.2 to 0.3 part of a leveling agent and 0.1 to 0.3 part of a defoamer. The component B is a hexamethylenediisocyanate tripolymer. A coating film corresponding to the two-component marking coating is high in strength, toughness and hardness, has relatively high wear resistance and weather resistance, ishigh in bonding strength with a pavement, and is long in service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a composition of a two-component marking coating and a preparation method thereof. Background technique [0002] Road markings play an important role in ensuring the safety and smoothness of highway traffic, and improving road appearance and appearance. Especially on mountainous roads, reflective markings at night are very important for road traffic. [0003] Road marking is an important part of road traffic safety facilities and even road construction, and it is one of the most effective ways to guide vehicles to drive in a standardized manner. Road marking paints are generally divided into two types: solvent-based and hot-melt. Solvent-based road marking paint refers to a marking paint that is constructed at room temperature and forms a film by solvent volatilization. This type of paint generally has a short service life, poor abrasion resistance, and long drying time. Hot-...
