PMMA (Polymethyl Methacrylate) type two-component road marking material and preparation method thereof

Abstract

The invention relates to a PMMA (Polymethyl Methacrylate) type two-component road marking material and a preparation method thereof. The PMMA type two-component road marking material is prepared from the following raw materials in percentage by mass: 40% of liquid PMMA resin, 15% of rutile titanium dioxide, 36% of 325# calcium carbonate, 0.5% of a BASF (Badische Anilin Soda Fabrik) antioxidant, 1.5% of an organic anti-settling agent, 0.5% of a BYK surface wetting agent, 2.5% of organic pigment, 0.3% of a molecular weight regulator, 1.5% of a plasticizer, 0.5% of a permeation aid, 0.2% of an acid value balancing agent and 1.5% of high-cobalt naphthenic acid-containing cobalt. The PMMA type two-component road marking material has the beneficial effects that the problems of poor weather fastness, slowly drying property and initial properties of the materials are solved; the product is green and environment-friendly material; and the PMMA type two-component road marking material as a novel material with low carbon emission is convenient to use, high in construction efficiency, simple to prepare and easy to operate.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a PMMA type two-component pavement marking material and a preparation method thereof. Background technique [0002] At present, the existing two-component marking paint is mainly epoxy type, polyurethane type, polyurea type, MMA (methyl methacrylate monomer) type. The main defect of the epoxy type is that it has poor weather resistance, and it is easy to pulverize and crack after being irradiated by ultraviolet rays. The solid drying time is too long, which is not suitable for the construction requirements of modern roads; the main defect of the polyurea type is high cost, the construction equipment is not only huge and complicated, but also the application is extremely difficult, and it is basically impossible to apply on a large scale; MMA (methyl methacrylate monomer) The type is an ester monomer. For long-term protection, it is not suitable for coating on alkaline ...

AI Technical Summary

Problems solved by technology

The main defect of the epoxy type is that it has poor weather resistance, and it is easy to pulverize and crack after being irradiated by ultraviolet rays. The solid drying time is too long, which is not suitable for the construction requirements of modern roads; the main defect of the polyurea type is high cost, the construction equipment is not only huge and complicated, but also the application is extremely difficult, and it is basically impossible to apply on a large scale; MMA (methyl methacrylate monomer) The type is an ester monomer. For long-term protection, it is not suitable for coating on alkaline cement. The main disadvantages are relatively slow drying time, poor adhesion, poor initial stain resistance, and prominent discoloration problems.
