Abstract

The utility model provides a reflecting glass bead which comprises a bead core and glass microballoons, wherein the glass microballoons are adhered to the outer surface of the bead core by use of powder coating. The reflecting glass bead has the advantages of strong reflecting strength and long effective reflecting distance. A ground marked line made of the reflecting glass beads is clear and bright either in sunny days or in rainy days and has exceptional reflecting performance. The reflecting glass bead provided by the utility model is a weatherproof reflecting glass bead.

Description

A kind of reflective beads

Technical field: the utility model relates to a kind of granulated glass sphere, particularly a kind of reflective beads.

Background technology: along with Economic development, motor vehicle is constantly popularized, and highway communication more and more becomes people's indispensable important component part of living, and highway traffic safety becomes the social safety problem that people generally pay attention to and pay close attention to.How effectively to avoid and reduce traffic accident taking place, the safety of life and property of effectively protecting people is that current the pressing for of people solves and social concern deeply concerned.

According to incompletely statistics, present most highway road traffic accident about 70% took place in rainy night, this is because following rainy night, visibility meter reduces greatly on the highway, reflecting effect was poor after traditional ground graticule soaked in humidity or by rainwater on the highway, and twenty or thirty rice just is difficult to see clearly at a distance, and the driver is difficult to differentiate the track, especially graticule loses the indication and the effect of standard traffic on motorway that does not have illumination and national highway, and rainy night is the district occurred frequently of accident; For make on the highway the reflective function of graticule with obvious excellence, people constantly improve the granulated glass sphere or the glass microballon product performance of the effect of present preparation sign, as Chinese patent application number is 96120575.X " crystallized glass microball and technology " and CN200710028239.4 " a kind of nanometer hot melt road line paint additive ", before a kind of be that existing granulated glass sphere or glass microballon product are improved, but it is monocrystalline or single glass pearl or glass microballon product; A kind of employing nanometer group material in back is formed, as nanometer SiO ₂, TiO ₂Waiting it only is weathering resistance to graticule, and easy clean not viscosity and dispersiveness are improved, and its reflective function be there is no much changes.

The particle diameter of its two granulated glass sphere now prepared or glass microballon is general less generally at the 100-800 micron, and effective reflective distance is short, generally is no more than 60 meters, overcast and rainy then shorter, generally is no more than 50 meters, and is even not reflective; Therefore how to make the ground graticule not only clear bright at fine day, simultaneously rainy night the sky also have better reflective function, bring into play guiding function better, effectively avoid and reduce the generation of traffic accident, be one of important basic condition that ensures highway traffic safety.

Summary of the invention:The utility model will provide a kind of reflective beads exactly, and its intensity of light reflection is big, and effective reflective distance adopts the clear bright reflective function in graticule rain or shine sky, ground of this reflective beads preparation superior.

The utility model reflective beads comprises pearl nuclear and glass microballon, and described glass microballon adheres on the outside surface of pearl nuclear border.

The utility model reflective beads, its described glass microballon adheres on the outside surface of pearl nuclear border with powder coating.

Reflective beads profile described in the utility model is the ball shape, and its particle diameter is the 0.6-2.2 millimeter.

Pearl described in the utility model nuclear is the granulated glass sphere of 0.5-1.5 millimeter for the particle diameter of common specific refractory power, or with ceramic particle or other inorganic hard particle of particle size range.

The specific refractory power of glass microballon described in the utility model is 1.7-2.4, and its particle diameter is the 25-80 micron.

Powder coating described in the utility model is Resins, epoxy or vibrin, or the mixing of Resins, epoxy and vibrin.

Contain titanium dioxide and/or lime carbonate that mass ratio is 10-30wt% in the powder coating described in the utility model.

The utility model reflective beads, be round-the-clock highlighted reflective beads, it is a kind of compound reflecting granulated glass sphere, the attached glass microballon that has high refractive index of outside surface at pearl nuclear can promote the Road safety grade significantly, overcomes the defective of traditional graticule, even also can become clear reflective as usual in rainy night, vehicle is taken their own roads, guarantee the rainy night traffic safety, can be used for the reflector marking system of motorway, mountain highway, urban road, airfield runway.

The performance comparison of the utility model reflective beads and simple glass pearl sees Table 1.

Below the present invention is done further detail explanation.

Description of drawings: Fig. 1 is the utility model granulated glass sphere product structure synoptic diagram;

Among the figure: 1. pearl nuclear, 2. glass microballon, 3. powder coating.

Embodiment:

Embodiment 1

1, with particle diameter be 0.6-0.8 millimeter, specific refractory power be 1.5 granulated glass sphere as pearl nuclear 1, drop into the drying machine drying and be warming up to 130-150 ℃; After pearl nuclear 1 heats up, disperse, fall into the container that powder coating 3 is housed through the vibratory screening apparatus multiple times of filtration; Consisting of mixing of Resins, epoxy and titanium dioxide of powder coating, the titanium dioxide add-on is the 10wt% of powder coating total amount, and median size is 30 microns, and second-order transition temperature is 70 ℃; Because the temperature of pearl nuclear 1 is higher than the second-order transition temperature of powder coating 3, examine on pearl that fusing adheres to one deck powder coating 3 on the 1 border outside surface; Molten pearl nuclear 1 with powder coating filters through vibratory screening apparatus, separate and reject defective microballon and unnecessary powder coating, with molten pearl nuclear 1 with powder coating 3 by disperseing screen cloth, disperse to enter be equipped with that specific refractory power is 1.9 or 2.2, median size is that glass microballon 2 temperature about 40 microns are in 100 ℃ the container; Because the temperature of high refractive index glass micro pearl 2 is higher than the second-order transition temperature that pearl is examined powder coating 3 on 1 outside surface, examine on the 1 border outside surface so make its fusing and stick to pearl firmly, make glass microballon 2 be wrapped in pearl and examine on the 1 outside surface border; After separating the rejecting unacceptable product after filtration, be the utility model reflective beads ball shape product; The reflective beads product cut size of preparation is the 0.7-0.9 millimeter.

Embodiment 2

All the other are identical with example 1 except that following explanation, pearl nuclear 1 is selected ceramic particle for use, also can select other inorganic hard particle for use, 1.2 millimeters of particle diameters, pearl is examined 1 dry heat be warming up to 180 ℃, powder coating 3 is Resins, epoxy and vibrin and the mixing of lime carbonate, the addition of lime carbonate be the powder coating total amount 20 wt %; The specific refractory power of glass microballon 2 is 2.4, particle diameter is 30 microns, and preparation reflective beads product cut size is between the 1.26-1.4 millimeter.
