Analysis of various reasons for hot melt marking line cracking

Analysis of the reasons for the application of hot-melt marking paint on the pavement cracking. As the season changes, some pavement markings will begin to change with the season and begin to crack in different shapes and degrees. Some are cracked longitudinally, and some are cracked. The cause of the cracking of the marking paint may come from the construction aspect, or from the force of the road surface or the road sinking. 总结如下: Hot melt marking paint manufacturers are summarized as follows:


施工时的温度,涂料在施工的时候,会有个加热的过程,一般热熔标线涂料在道路施工的时候温度要比熔炉的温度低 20 摄氏度左右。 (1) Temperature during construction. When the paint is applied, there will be a heating process. Generally, the temperature of hot-melt marking paint during road construction is about 20 degrees Celsius lower than the temperature of the furnace .

路面温度过低,则会导致高温度的涂料在短时间内冷却,直接影响涂料本身跟路面之间的融合程度。 (2) If the road temperature is too low, it will cause the high-temperature paint to cool in a short time, which directly affects the degree of fusion between the paint itself and the road.

施工速度的影响,一般施工过程中,厚度控制在 1mm-2mm 之间,但施工划速要保持匀速状态。 (3) The impact of construction speed. In general construction, the thickness is controlled between 1mm-2mm , but the construction speed must be kept at a uniform speed.

路面受到外力影响作用产生裂纹。 (4) The road surface is affected by external forces and cracks occur.

涂料本身的原因。 (5) The reason for the coating itself. The coating itself is a polymer mixture without a fixed melting point. When heated, it will soften with increasing temperature and continue to be molten when heated. 生产热熔涂料常用的就是石油树脂。 Petroleum resins are commonly used by hot-melt coating manufacturers to produce hot-melt coatings. Secondly, the plasticizer itself also plays a certain auxiliary role in the coating. Polymer stiffness decreases and flexibility increases.
