Problems solved by technology

[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 hig

Example Embodiment

[0021] Example 1

[0022] Mix 15 parts of modified petroleum resin, 30.1 parts of calcium carbonate, 30.1 parts of quartz seconds, 5 parts of titanium dioxide, 18 parts of glass beads, and 1.8 parts of soybean oil and soybean oil modified alkyd at 200°C. In 15 minutes, a hot-melt pavement marking paint material composition was obtained; the modified petroleum resin used 1900 g of crude dicyclopentadiene with a purity of 83%, 900 g of C5 fraction and 1000 g of toluene, which were added to a high-pressure reactor with agitator Stir uniformly in the medium, slowly heat up to 260°C, and the reaction pressure is 2.0Mpa. After reacting at 260°C for 6 hours, the unpolymerized light components are first distilled out under normal pressure, and then the oligomers are distilled out under reduced pressure to obtain the basis of the molten state. Petroleum resin 2000g; under the protection of nitrogen, add 26g of modifier maleic anhydride, increase the temperature to 200°C and keep it unchan...

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...
