Problems solved by technology

Although this dyeing method can avoid the expensive or toxic shortcomings of directly adding cerium oxide, titanium oxide, silver compound, gold compound, copper compound, cadmium sulfide, cadmium selenide, etc. The dyed film belongs to medium or low temperature glass glaze, and its adhesion, acid and alkali resistance are not good. Because it is buried on the road surface and has multiple effects of tire rolling, acid rain, sewage and sunlight, the dyed layer of the glass road stud is prone to erosion. The phenomenon of peeling or blackening will affect the reflective function

preparation example Construction

[0047] In addition, the present invention further provides a method for preparing a glass road stud, comprising steps: (A) melting a glass raw material to form a glass paste; (B) placing the glass paste in a molding mold to shape it into a road nail shape , wherein the molded glass road stud has a base and a protrusion, the base is connected to the protrusion, and the protrusion protrudes from the base; (C) slowly cooling the road stud; (D) coating the surface of the cooled glass road stud with a metal ion material layer (that is, a material layer containing chromogenic metal ions); (E) heating the glass coated with the metal ion material layer coating Block to a suitable first temperature above the softening temperature (about 550° C.), so that the metal ions of the metal ion material layer penetrate from the surface of the glass block into the subsurface layer and develop color; and (F) quenching (for example, quenching with wind cooling) Temper the glass block.

Embodiment 1

[0075] The colorless glass melt paste is molded into a road stud-shaped glass block in a cat's-eye road stud mold, and then the formed glass block is slowly cooled to normal temperature in an annealing furnace.

[0076] Then, silver nitrate, iron oxide, and water are mixed thoroughly in a weight ratio of 1:50:50 to form a paste, and then the paste is applied to the entire surface of the glass block with a brush, and the glass block is reheated to an appropriate temperature above the softening point. The toughening temperature is maintained at 675°C for 8 minutes to allow silver ions to infiltrate from the surface of the glass block, and then it is taken out and quenched by air cooling to form a yellow cat-eye tempered glass road stud (yellow glass block). After cleaning, the aluminum metal reflective layer is coated on the bottom of the glass block by vacuum evaporation method to obtain a yellow cat's eye toughened glass road stud with yellow reflective effect, such as figure ...

Embodiment 2

[0079] The colorless glass melt paste is molded into a road stud-shaped glass block in a cat's-eye road stud mold, and then the formed glass block is slowly cooled to normal temperature in an annealing furnace.

[0080] Next, mix silver oxide, chromium oxide, and rosin oil in a weight ratio of 1.5:50:70 to form a paste, then spray the liquid on the entire surface of the glass block with a spray gun, and reheat the road stud to an appropriate temperature above the softening point. The tempering temperature is maintained at 685°C for 8 minutes to allow silver ions to penetrate into the glass block and turn yellow. Take it out and use wind cooling to quickly cool it into a yellow cat's-eye tempered glass road stud (yellow glass block). After cleaning the residue on the surface, the aluminum metal is plated on the bottom of the glass block by vacuum evaporation method to form a reflective layer, and the yellow cat's-eye toughened glass road stud with yellow reflective effect is obtai...

Abstract

Provided is a glass spike and a manufacture method thereof. The yellow and red toughened glass spike is obtained through an ion permeating chromogenic method, namely a metal ion coating with chromogenic effect is coated on the glass surface of the colorless glass spike to serve as a coating layer, and then the coating is heated to the proper first temperature higher than the softening point, so that the metal ions with the chromogenic effect permeate into the glass spike to enable the glass spike to be colored, the yellow or red toughened glass spike performed with quenching through the air can be taken out at the first temperature.

Description

technical field [0001] The invention relates to a glass road stud and a preparation method thereof, in particular to a glass road stud endowed with a coloring effect by ion penetration and color development and a preparation method thereof. Background technique [0002] Road studs are also called road studs, road signs, markings, reflective road studs, etc. The use of road studs is mainly to distinguish lanes and provide warning functions, so that drivers can distinguish the range, characteristics and direction of the road in a more comfortable situation, because If there are no road studs, it will be difficult for the driver to distinguish the range, characteristics and direction of the marking paint used to divide the road due to dust accumulation or dim lighting or rain, which will easily lead to confusion and fatigue, and even cause accidents. Therefore, on higher roads, protruding spikes will be installed to improve the driver's alertness, comfort and safety. So far, t...
