Heat molten pavement marking line paint

Abstract

The invention belongs to the technical field of paint, and particularly relates to heat molten pavement marking line paint. The heat molten pavement marking line paint is mainly prepared from the following ingredients in percentage by weight: 12 to 25 percent of modified petroleum resin, 5 to 10 percent of color pigments, 45 to 60 percent of filling materials, 16 to 23 percent of reflecting materials and 1 to 5 percent of plasticizers. The pavement marking line paint provided by the invention has the advantages of environmental-friendly effects, light hue, good water-resistant and alkali-resistant corrosion performance, low fusion viscosity, good flowability, good heat resistant stability, good weathering resistance, longer service life and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a hot-melt road marking paint. Background technique [0002] The main disadvantages of petroleum resins used in road marking paints produced in China at present are: poor heat resistance stability, poor fluidity, poor adhesion, and poor compatibility with polar resins. With the development of modernization, people have higher requirements for hot-melt road marking paint. However, the existing road marking paints have the following disadvantages: 1. The hot-melt marking lines are thermoplastic coatings that are soft and sticky when the temperature is high in summer, and the anti-fouling property is not good, which brings difficulties to the electronic police to take pictures and collect evidence, and affects the image of the city. , requiring higher pollution resistance and thermal stability; 2. Urban roads are mostly located in the living and working areas of residents. Nowaday...

[0002] The main disadvantages of petroleum resins used in road marking paints produced in China at present are: poor heat resistance stability, poor fluidity, poor adhesion, and poor compatibility with polar resins

However, the existing road marking paints have the following disadvantages: 1. The hot-melt marking lines are thermoplastic coatings that are soft and sticky when the temperature is high in summer, and the anti-fouling property is not good, which brings difficulties to the electronic police to take pictures and collect evidence, and affects the image of the city. , requiring higher pollution resistance and thermal stability; 2. Urban roads are mostly located in the living and working areas of residents. Nowadays, occupational health requirements are high, and people’s tolerance to odors is reduced, requiring materials to be safer and more environmentally friendly; 3. Cement concrete There is a layer of alkali on the surface of the road surface, and the existence of the alkali layer will affect the good adhesion between the marking paint film and the road surface, and the marking material is required to have good alkali corrosion resistance; 4. The traffic flow is large, and the drying time is required to be short , easy maintenance, good recoatability, long service life to reduce traffic interference

Although the material has good fluidity and compatibility, it has a high softening point, poor hue, poor weather resistance and thermal stability, and has a certain impact on the environment due to its strong odor.
