Problems solved by technology

[0006] When changing the fluidity of hot-melt coatings, it is generally achieved by increasing the resin content or using various processing aids, which will make it difficult to dry the coating to a certain extent, and at the same time cause the coating film to be soft and easy to dry. sticky dirt
[0007] In addition, the more important point is that increasing the content of additives or resins in the coating will increase the manufacturing cost of the coating at the same time

Abstract

The invention provides a hot-melting road-marking coating and a preparation method thereof. The coating comprises the following components in percentage by weight: 13%-17% of C5 petroleum resin, 0.5-1.5% of EVA, 0.5-1.5% of PE wax, 0.5-1% of dioctyl ester, 3-4% of a pigment, 17%-22% of glass microspheres, 16%-21% of quartz sand, 36%-42% of ultra-fine talcum powder and 0.2%-0.4% of permeable crystallization-type water-resistant rubber powder. The fluidity of the coating is increased, the heating and stirring time is decreased and the production energy consumption is saved. The construction efficiency is improved, the melting temperature is decreased and the production energy construction is saved and meanwhile, the coating has the advantages of very strong adhesion force, abrasion resistance and long service life, good quality assurance degree and stable product quality.

Description

technical field [0001] The invention relates to a resin coating used for cement concrete or asphalt road pavement marking, that is, a hot-melt road marking coating. technical background [0002] Road marking paint is a paint that is applied on the road to mark road markings. Road marking paint is a safety mark and a "language" in road traffic. Road markings are an important part of traffic facilities. Clear and complete road markings can give drivers and pedestrians a good conditioned reflection, which can effectively reduce accidents and improve driving efficiency. A statistic shows that the correlation probability between road markings and accidents is 70%, which can improve transportation efficiency by 30%. The traffic flow on the highway is increasing, and the driving speed is gradually increasing. Therefore, higher requirements are put forward for the development and matching, safety, economy, durability and aesthetics of traffic safety facilities. [0003] Overs...
