Problems solved by technology

However, due to the low solid content of normal temperature road marking paint, the road marking coating is thin (generally only 0.1-0.3mm), so it is difficult to ensure the hardness and strength of the coating, and it cannot adhere to enough glass Reflective beads can not achieve the reflective effect at night, and the service life is short (generally only about 3 months), resulting in frequent construction of road marking lines, which not only affects traffic operations, but also increases the manpower and material resources of construction marking lines
Some thick-build road marking paints currently used have high solid content (generally more than 65%), reflective properties, and long service life. However, traditional thick-build road marking paints need to be pre-heated before use. Solvent-based high-build coatings, although water-based high-build coatings have also been researched and developed in the follow-up, but they often have slow drying speeds and long construction periods, which affect vehicle traffic

Abstract

The invention relates to the technical field of road marking coatings, in particular to a waterborne high-build marking coating and a preparation method thereof. The coating is prepared from a waterborne acrylic emulsion, a water soluble dispersant, silicon-aluminum porous micro-spheres, inorganic filler, chlorinated paraffin, a waterborne polyethylene wax emulsion, methylene dichloride, ethanol,water, lithium silicate, sodium silicate, dietary alkali, sodium chloride, a coupling agent, a coalescing agent and pigment. The raw materials have a synergistic effect in a limited dosage range, theprepared high-build marking coating is high in solid content, drying speed and permeability, has strong ground binding force and high strength and is resistant to shoveling and anti-rutting, and scraping and applying construction can be performed at normal temperature. According to the preparation method, the mixing sequence, the heating temperature and the stirring time of the raw materials are limited, emulsification shearing is performed under the condition of certain pressure, so that the prepared high-build marking coating is good in stability, and the drying speed, the ground binding force and the strength of markings prepared with the coating are further increased.

Description

technical field [0001] The invention relates to the technical field of road marking paint, in particular to a water-based thick build marking paint and a preparation method thereof. Background technique [0002] Road demarcation lines, crosswalks and seat belt markings on highways, expressways, urban roads, airports and docks are important signs for traffic flow, vehicle operation, pedestrian safety and traffic violation accidents. Due to the sharp increase in road paving rate, higher requirements are put forward for the marking paint on the road surface. At present, the most widely used road marking paint is the normal temperature road marking paint. Normal temperature road marking paint is widely used because of its simple production process and convenient construction and application. However, due to the low solid content of normal temperature road marking paint, the road marking coating is thin (generally only 0.1-0.3mm), so it is difficult to ensure the hardness and s...
