Description of the main application information of carbon five petroleum resin for hot melt road marking paint

Carbon five petroleum resin for hot-melt road marking paint is an insulating material, potting material and casting material. Aliphatic petroleum resin has good weather resistance and can be made into outdoor high-voltage insulators to replace ceramic products. It has the characteristics of light weight, small size, good impact resistance and easy production. Because of its excellent electrical properties and color stability, it can be used as a packaging material for light-emitting diodes. After being plasticized with polyols, it is widely used in potting of transformers, high voltage coils and various small electronic components. Such products can simultaneously meet the requirements of good thermal shock resistance, high thermal deformation temperature, and excellent critical electrical characteristics.

Because the alicyclic petroleum resin has high heat resistance, small curing shrinkage, and good dimensional stability, it can be used to make petroleum cast mold tires (plastic molds). It has the advantages of easier processing than metal molds, lower price, lighter weight, and convenient molding operation. It is especially suitable for composite parts with large molding size, complex profile, high precision and low output. It has been widely used in aircraft and automobile manufacturing.

Coatings for road signs and road markings are generally called road paints, and mainly include normal temperature type, heating type and melting type.

The resins used in road marking paint mainly include: acrylic resin, alkyd resin, chlorinated rubber, modified alkyd resin, epoxy resin, petroleum resin, etc. Compared with other resins, petroleum resin has the advantages of low price and excellent performance. The resin has good adhesion to concrete or asphalt pavement, and has abrasion resistance and water resistance. In addition, petroleum resin has good affinity with inorganic substances, easy to coat, good weather resistance, fast drying, and high firmness. , Petroleum resin can not only improve the physical and chemical properties of the coating, such as hardness, impact strength and bending, but also improve its UV resistance and weather resistance. The longest service life can reach 3 years. The usage amount accounts for 25%-30% of the total road marking paint.
