Raised pavement marker with good anti-impact performance and manufacturing method thereof

Abstract

The invention belongs to the technical field of a raised pavement marker, and discloses a raised pavement marker with good anti-impact performance and a manufacturing method thereof. The raised pavement marker comprises a circular truncated cone and a hemispheroid, wherein each of the circular truncated cone and the hemispheroid is prepared from the following ingredients in percentage by weight: 67 to 78 percent of SiO2, 6 to 10 percent of Na2O, 9 to 11 percent of B2O3, 1 to 6 percent of CeO2, 1 to 6 percent of TiO2, 0 to 1 percent of ZrO2, 1 to 3 percent of BaO and 0 to 5 percent of PbO, wherein the sum of the weight percentage of all ingredients is 100 percent. According to the manufacturing method, firstly, raw materials are melted and pressed into a glass blank body; then, the glass blank body is put into a toughening furnace for toughening treatment; finally, the glass blank body subjected to toughening treatment is subjected to quenching treatment to obtain the glass blank body.The adhering degree and the occlusion degree of the glass body and the pavement are enhanced, so that the whole cannot easily fall off; the whole anti-impact performance of the glass body is enhanced;the condition that tires are pierced by glass disintegrating slag formed after the crushing is avoided. The raised pavement marker has the advantages of wear resistance, corrosion resistance and hightemperature resistance, and is suitable for being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of raised road signs, and in particular relates to a night elf with good impact resistance and a manufacturing method thereof. Background technique [0002] Night Elf, which is a product called raised road markings in the prior art, is a raised marking block fixed on the road surface to act as a marking line, and can be used to mark centerlines, lane boundaries, and edge lines on expressways or other roads; It can also be used to mark dangerous road sections such as bends, entrance and exit ramps, diversion markings, narrowing roads, and road obstacles. [0003] Since the raised road signs are generally glass products, when the existing raised road signs are used on some roads with bad road conditions or roads with many vehicles, brittle fractures will occur, and the broken glass fragments will puncture the tires, causing traffic accidents; At the same time, during the manufacturing process of the existing ...

AI Technical Summary

Problems solved by technology

[0003] Since the raised road signs are generally glass products, when the existing raised road signs are used on some roads with bad road conditions or roads with many vehicles, brittle fractures will occur, and the broken glass fragments will puncture the tires, causing traffic accidents; At the same time, during the manufacturing process of the existing raised road signs, micro-cracks are easily formed due to insufficient melting, fast or uneven cooling, collision or friction with solid materials, etc., resulting in brittle fracture and cracking. Multiple Fragments, Extremely Low Security
