Problems solved by technology

Foreign water-based road marking paints mostly use anionic pure acrylic emulsion and styrene-acrylic emulsion as the main base material, and are prepared by adding a small amount of water-soluble or water-dispersible amine-containing polymer and volatile alkali. The material requirements are relatively high (at present, the pavement materials mainly include asphalt, cement, and gravel). If the evaluation is not done before construction, it will often lead to large-scale peeling off of the coating film
Domestic Changzhou Ferrum Automobile Coatings Co., Ltd., the invention patent of which the authorized announcement number is CN1324099C discloses a self-crosslinking water-based road marking paint and its preparation and use method. It is obtained by using silicon acrylic emulsion. When using in the field with many or poor road surfaces, it is necessary to spray a layer of two-component water-based epoxy primer before the construction of the water-based road marking paint. After the primer is dry, spray the road marking paint, which solves the problem of water-based road marking paint. Adhesion on various road surfaces, but there are defects of cumbersome construction and high cost, and the requirements for the drying of the primer at the construction site are very strict. Once the judgment is wrong, it will lead to the problem of large-scale peeling off of the coating film

Description

technical field [0001] The invention relates to the field of paint manufacturing, and in particular to a super wear-resistant water-based road marking paint and a preparation method thereof. Background technique [0002] Road markings are an important part of roads, which refer to signs on the road surface that use lines, arrows, characters, marks, etc. to convey traffic information such as guidance, restrictions, and warnings to traffic participants, which can control and guide traffic Road markings are obtained by applying road marking paint to the road surface. [0003] At present, the existing road marking paints mainly include normal temperature type, hot-melt type and water-soluble type. Among them, the normal temperature type paint will have a large amount of organic solvent volatilization in the process of production and use, which will not only pollute the environment, but also the strength of the paint is low, Not wear-resistant, short service life, and poor affin...
