Abstract

The invention discloses a convex hot-melt marking line. The convex hot-melt marking line is prepared from the following raw materials in parts by weight: 10-15 parts of modified C5 petroleum resin, 5-10 parts of polyurethane, 30-45 parts of glass beads, 30-40 parts of nano silicon dioxide, 10-15 parts of calcium carbonate, 10-15 parts of titanium dioxide, 3-5 parts of polypropylene wax, 2-3 partsof stearic acid, 1-2 parts of glyceryl stearate, 1-3 parts of a flatting agent and 2-5 parts of a plasticizer. The invention also discloses a preparation method of the convex hot melt marking line. The modified C5 petroleum resin not only has high polarity, and also endows the convex hot-melt marking line with good corrosion resistance and film forming performance; the calcium carbonate and the titanium dioxide are added in a preparation process, so that the reinforcing, anti-aging and filling effects can be exerted; wear resistance of the marking line can be enhanced through addition of the polyurethane and the nano silicon dioxide; and the modified C5 petroleum resin has high polarity, and then can be better blended with polyurethane, so that stability of the system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of marking lines, in particular to a raised hot-melt marking line and a preparation method thereof. Background technique [0002] There are three types of road markings: hot melt type, water type and normal temperature solvent type. With the environmental protection of modern construction and the high requirements for wear-resistant, anti-skid, weather resistance and durability of markings, low-cost hot-melt markings have become the first choice for road markings. When changing the fluidity of the hot-melt marking line, it is generally achieved by increasing the resin content or using various processing aids, which will make it difficult to dry the marking line to a certain extent, and at the same time cause the coating film to be soft and easy to stick to dirt. In addition, the more important point is that increasing the content of additives or resins in the marking line will increase the manufacturing co...
