。However, the current situation is that traffic regulations in the spring are almost impossible as the marking lines have been torn off by chains and spiked tires during the winter. Up to now, attempts have been made to use adhesive sheets (PVC-based sheets) and adhesive sheets (thermo-fusible resin-based) as marking materials that are durable during the winter, but adhesive sheets have poor work efficiency. Due to its ease of use, it is only used as part of the crosswalk strip. In addition, adhesive sheets have a high risk of peeling, so they are rarely used. The present invention was made to solve these problems, and provides a heat-welded road marking material that can provide a coating film that exhibits excellent durability even against severe impact and friction. be.

ある。If the lower alkyl ester of acrylic acid is less than 3% by weight, the melt viscosity will be too high and workability will be poor; if it exceeds 40 parts by weight, the melt viscosity will be low, but the flexibility at low temperatures will be poor. Undesirable. As the lower alkyl ester of acrylic acid, esters of alkyl acrylic acids having 1 to 4 carbon atoms, particularly ethyl acrylate, are preferred. The softening point of ethylene-acrylate copolymer is 70-150℃

Petroleum resins include aliphatic petroleum resins, copolymerized petroleum resins (based on aliphatic and aromatic monomers), acid and ester modified products of these petroleum resins, aromatic petroleum resins, and water additives of these petroleum resins. Of these, one or more types are used. In the present invention, the ethylene-acrylate copolymer and the rosin-modified resin or petroleum resin are mixed to form a binder, and the mixing ratio of the two is 10 to 50 parts by weight of the ethylene-acrylate copolymer. The optimal range is 10 to 80 parts by weight of the rosin-modified resin or petroleum resin (rosin-modified resin and petroleum resin can be used in any ratio).

Parts by weight are used, particularly preferably from 2 to 20 parts by weight. When the amount is less than 1.5 parts by weight, the coloring power is insufficient and visibility is reduced, and when it exceeds 20 parts by weight, the melt viscosity is high due to an increase in oil absorption, and the thixotropy is also strong, resulting in a decrease in workability.

路標示材料が得られる。The results are shown in Table 1. According to the present invention, by using an ethylene-acrylate copolymer containing a lower alkyl ester of acrylic acid as a polymer component and a petroleum resin or a rosin-modified resin as a caking agent, chain cars and spikes can be easily removed during snowfall. A heat-welded road marking material can be obtained that can provide a paint that exhibits sufficient durability (does not peel off) even when vehicles with tires are passing through.
