Abstract

The invention discloses a microwave easy-to-remove modified hot-melt marked line for a cement pavement and a preparation method. The microwave easy-to-remove modified hot-melt marked line is preparedfrom the following components in parts by weight: 20-40 parts of modified C5 petroleum resin, 10-20 parts of EVA resin, 5-20 parts of terpene resin, 5-10 parts of a plasticizer, 2-5 parts of a leveling agent, 10-30 parts of titanium dioxide, 10-20 parts of siliceous low-dielectric-constant filler, 10-30 parts of wave-transmitting glass beads and 5-40 parts of a modified composite microwave absorber. According to the invention, an impedance matching structure is formed by adjusting the structure and material composition of the hot-melt marked line, and the propagation loss of microwaves in thehot-melt marked line is reduced. The obtained modified hot-melt marked line can meet the pavement performance of a conventional hot-melt marked line, can be quickly softened and efficiently separatedfrom the cement pavement after absorbing microwaves, basically has no residue on the cement pavement after being heated and removed by the microwaves, and does not damage the original surface textureof the cement pavement; and the preparation method and the clearing method are simple and efficient.

Description

technical field

[0001] The invention relates to the technical field of road markings, in particular to a microwave easy-to-clear modified hot-melt marking for cement pavement and a preparation method thereof. Background technique

[0002] Traffic marking is a traffic safety infrastructure that adheres to the road surface and has the function of indicating and guiding. It plays a very important role in rationally dividing lane boundaries, providing continuous traffic information flow, and ensuring smooth and safe driving of vehicles. Although new types of road marking tapes such as water-based marking lines, two-component marking lines, and preformed marking tapes have emerged in recent decades, hot-melt type marking lines are currently the most widely used in my country. At the same time, the increasing scale of road reconstruction and expansion and the demand for optimal allocation of road resources have put forward higher requirements for the flexibility of traffic marking...
