MMA bicomponent protruding road coating and preparation method and application thereof

Abstract

The invention belongs to the technical field of road coatings, and in particular relates to an MMA bicomponent protruding road coating and a preparation method and an application thereof. The coatingis prepared from a component A, a component B and an initiator in a mass ratio of 50: 50: 2. The component A is prepared from the following raw materials in parts by weight: 20-30 parts of MMA resin 1#, 3-8 parts of a pigment, 20-40 parts of natural quartz sand, 20-40 parts of glass beads and 5-12 parts of an auxiliary agent. The component B is prepared from the following raw materials in parts byweight: 20-30 parts of MMA resin 2#, 3-8 parts of a pigment, 20-30 parts of natural quartz sand, 20-40 parts of glass beads and 5-12 parts of an auxiliary agent. When the road coating is used, the components A and B are uniformly stirred, separately, and the initiator is added into the component B in parts by weight. Then the mixture is mixed with the component A uniformly, the mixture is added into a hopper of a lineating machine, and the coating is protruded, formed and cured to obtain the road coating. The road coating is free of volatile solvent and green and environment-friendly. In thecuring process, heating is needed, so that the road coating is green and environment-friendly. The road coating has the advantages of being unlikely to crack, firm and good in impact resistance, pressure resistance and durability and weather resistance.

Description

technical field [0001] The invention belongs to the technical field of road coatings, in particular to an MMA two-component protruding road coating and its preparation method and application. Background technique [0002] Road marking paints serve as reminders and warnings, and are essential for smooth transportation and the safety of people and vehicles. At present, most of the existing protrusion-type road coatings are hot-melt type. They need to be heated and melted to a fluid state before they can be used, and their durability and weather resistance are limited. There are disadvantages such as easy deformation when heated, and liquefaction is required when heated. Gas or oil is used as the heating source, which consumes energy, wastes resources, and increases costs. Therefore, traditional road coatings have shortcomings in energy saving and environmental protection, and cannot meet the current market demand for energy-saving, green and environmentally friendly new produc...

At present, most of the existing protruding road coatings are hot-melt type, which need to be heated and melted to a fluid state before use, and the durability and weather resistance are limited, and there are disadvantages such as easy deformation when heated, and need to be liquefied when heated. Gas or oil is used as the heating source, which consumes energy, wastes resources, and increases costs. Therefore, traditional road coatings have shortcomings in energy saving and environmental protection, and cannot meet the current market demand for energy-saving, green and environmentally friendly new products.
