A kind of normal temperature solvent type road marking paint and preparation method thereof

Abstract

The invention belongs to the technical field of road mark paint, and more specifically relates to a normal temperature solvent-type road mark paint, and a preparation method thereof. The normal temperature solvent-type road mark paint is mainly prepared from, by weight, 350 to 380 parts of an acrylic resin, 20 to 30 parts of branching modified polysulfone resin, 30 to 40 parts of epoxy resin, 10 to 12 parts of propylene glycol methyl cyclohexyl ether, 8 to 10 parts of diisobutyl nylon acid ester, 10 to 15 parts of a plasticizer, 8 to 10 parts of an antisettling dispersant, 80 to 100 parts of apigment, 350 to 380 parts of a filling material, 8 to 10 parts of toluene, 35 to 40 parts of butyl acetate, 55 to 70 parts of butanone, and 10 to 20 parts of ethanol. The acrylic resin is a monomer prepared from methyl methacrylate and butyl methacrylate at a ratio of 4:1; the branching modified polysulfone resin is prepared via adding a Si-containing chain extender in polymerization; the solid content ranges from 70 to 80%; and excellent road combination force, impact resistance, and water resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of road marking paint, in particular to a normal temperature solvent-based road marking paint and a preparation method thereof. Background technique [0002] Road marking paint is a paint that is applied on the road to mark road markings. It is a safety mark and a "language" in road traffic. Road markings are an important part of traffic facilities. Clear and complete road markings can give drivers and pedestrians good conditioned reflexes, which can effectively reduce accidents and improve driving efficiency. [0003] There are four types of road marking paints used in my country: hot-melt type, two-component type, water-based and normal temperature solvent type. Normal temperature road marking paint is a traditional product of road marking paint in my country. It is favored by users for its advantages of convenient construction and low one-time investment. However, unlike other paints, road marking paint...

AI Technical Summary

Problems solved by technology

Therefore, although the normal temperature solvent-based marking paint has the advantages of convenient construction and use, the current common normal temperature solvent-based marking paint has low solid content, thin coating film, low bonding force with the road surface, water resistance, heat resistance and Low impact performance, resulting in short service life of marking lines formed by normal temperature solvent-based marking paint
