What is the difference between hot melt wire paint and cold?

Road traffic is divided into: hot melt marking paint, room temperature cold paint marking paint, color ground slip road marking, vibration ground anti-skid backlight road marking and prefabricated road marking, hot melt marking paint is currently widely used in my country’s road traffic. A kind of line drawing process, the project construction time is short, the use performance is high, and the construction cost is low.

The road marking ground is exposed to the sun, rain, snow and snow, and the impact friction coefficient of the car, so there are strict requirements for its characteristics. First, the boring time is short and the actual operation is simple to reduce traffic interference; second, the reflective surface requires strong working ability, bright colors, and strong brightness, so as to have good visibility during the day and night; second, it must have anti-skid performance and use performance, In order to ensure the safety and service life of the manhole.

Road marking, industrial area road, factory underground parking lot line, underground parking lot line, school road line, occupation residential area line and other construction projects are divided into cold paint line and hot melt line, and the colors are divided into light yellow and White.

1. Cold paint line: Use special distance public cold building paint, body spray paint, average thickness, and fresh air color. Including parking lot, no-parking double yellow line area, safe passage line, water retaining belt, guide arrow.

2. Hot-melt coating line: Hot-melt coating is made of petroleum resin, EVA, PE wax, color filling and other materials, the normal temperature is powder, and the hot-melt kettle is heated to 180-220℃, while mixing and heat insulation 3- After 5 minutes, the subject moves and sticks to the ground to form a hard coat. It has the characteristics of rich linear shape and strong performance. The light-back beads on the surface of the building have a good light-back effect at night, and are widely used in the driving of highways and big cities. When using the voucher, according to the customer’s request, we will provide conflicting specification types for you to choose.

Hot melt wire coating material characteristics

1. Strong adhesion: The epoxy resin composition is uniform, and the bottom is coated with a special rubber polyurethane elastomer, which has strong adhesion. Make sure the construction technique is fair and it is not easy to swell the scattered scenery.

2. Good crack resistance: Hot-melt pavement signs may crack at will due to changes in temperature difference. It is estimated that a sufficient amount of EVA epoxy resin should be used during painting to prevent cracking.

3. Bright colors: using high-quality outer film color paste, uniform preparation, good aging resistance, long-term bursting and fading

4. High sizing rate: small relative density, large volume and high sizing rate are a major feature of everyone.

5. Good stain resistance: The quality and use of PE wax is the key link of stain resistance.
