Problems solved by technology

An important indicator of road traffic marking paint is the adhesion between the paint and the road surface and the glass beads used to reflect light. However, the common problem in some trial water and water-soluble paint markings is that the paint and road materials ( Especially the cement pavement) and glass beads have poor bonding force, and this bonding force will be greatly weakened when soaked in rainwater, resulting in the reduction of the reflective ability of the marking line and shortening the service life of the marking line

Abstract

The invention discloses a water-based long-acting reflective road traffic marking paint and preparation and usage, which is characterized by the following: comprising with adhensive, filler, color, coupling agent, each aids and organic dissolvent. This invention can keep road traffic marking long life and high reflecting property.

Description

Technical field: [0001] The invention relates to a water-based long-lasting reflective road traffic marking paint and its preparation and application methods. Background technique: [0002] At present, road traffic marking paints used on high-grade highways, urban roads and expressway pavements are mostly three types: normal temperature solvent type, heating solvent type and hot melt type. In recent years, due to the various advantages of water-based coatings, such as non-toxicity, low volatile organic compounds (VOC), no heating required for construction, easy cleaning of machines and tools, and thinner thickness, etc., it has gradually been recognized by people in the industry and has become a road marking coating. It is a rookie emerging in China, especially to provide long-lasting night bright reflective instructions for roads that lack lighting, thereby improving driving safety to a large extent. An important indicator of road traffic marking paint is the adhesion betw...
