Problems solved by technology

[0003] Most of the road marking paints commonly used in the prior art are hot-melt road marking paints. The disadvantages of this marking paint are: low construction efficiency, poor recoatability, high energy consumption (need to be heated to 180-220 ° C), The poor road conditions are easy to fall off, and the low boiling point VOC volatilizes seriously during construction, which is easy to pollute the environment; thus limiting its application in the future marking paint

Abstract

The invention discloses an environment-friendly double-component marking coating as well as a preparation method, a use method and application thereof. The coating consists of a component A, a component B and glass beads, wherein the component A comprises the following components in parts by mass: 50 to 55 parts of 655 resin, 45 to 50 parts of rutile type titanium dioxide, 50-60 parts of calcium carbonate, 0.1 to 0.2 part of a rheological agent 2; 0.2 to 0.4 part of a dispersing agent, and 0.1 to 0.2 part of a rheological agent 1; the component B comprises the following components in parts by mass: 50 to 55 parts of 659 resin, 45 to 50 parts of rutile type titanium dioxide, 50 to 60 parts of calcium carbonate, 0.1 to 0.2 part of a rheological agent 2, 0.2 to 0.4 part of a dispersant, 0.1 to 0.3 part of a rheological agent and a curing agent; wherein the mass ratio of A to B is 1:1, and the glass beads account for 18-25% of the sum of the mass of A and B; the part number of the rheological agent 1 in A is smaller than that in B; the addition amount of the curing agent is 1.5-2.0% of the mass sum of the resin in the component A and the component B; the rheological agent 1 is fumed silica with the specific surface area of (200 + / - 25) m2 / g, and the rheological agent 2 is a low-molecular-weight polymer solution containing urea / carbamate functional groups.

Description

technical field [0001] The invention belongs to the technical field of traffic marking paint, and in particular relates to an environment-friendly two-component marking paint and its preparation method, use method and application. Background technique [0002] With the continuous deepening of national policies and regulations such as low-carbon energy saving, ecological environmental protection and high-quality development, there is a significant demand for the development of new road marking paints with excellent performance and environmental protection. For road marking paint, it can not only guide vehicles to drive in a standardized manner and ensure driving safety, but more importantly, the two-component marking paint is reactive, and VOC will not be released during the construction and curing process. The purpose of reducing environmental pollution and protecting human health. [0003] Most of the road marking paints commonly used in the prior art are hot-melt road mar...
