Embodiment Construction

[0025] A method for preparing magnetic fully aluminized reflective glass beads, comprising the following specific steps:

[0026] (1) Preparation of plating solution:

[0027] 6 parts of NiCl 2 ·6H 2 O, 3 parts of sodium citrate, 0.5 part of potassium sodium tartrate are dissolved in 80 parts of distilled water, and then 80 parts of NaH with a concentration of 5wt% are taken 2 PO 2 ·H 2 O aqueous solution is added wherein, and finally adding 6 parts of concentrations wherein is 25wt% ammoniacal liquor, promptly obtains plating solution after stirring;

[0028] (2) Plating:

[0029] After pretreatment, the glass beads were put into the above-prepared plating solution, heated to 70°C at a heating rate of 4°C / min under stirring, and then kept for 40 minutes, filtered and washed with distilled water to obtain coated Ni- Magnetic glass beads of P alloy layer;

[0030] (3) Bead planting:

[0031] Coat the acrylic resin adhesive on the PET film A, and after drying in an oven ...

Abstract

The invention discloses a preparation method of a magnetic complete-aluminum-plating reflective glass micro-bead. According to the present invention, a magnetic Ni-P alloy layer is arranged on the surface of the core of a glass micro-bead by using a chemical composite plating process, and an aluminum-plating layer is precipitated on the surface of the alloy layer through two high temperature plating treatments, such that the all-round aluminum plating on the surface of the glass microsphere can be achieved, and it can be ensured that the aluminum-plating layer is attached onto the surface of the glass micro-bead being not embedded into the bead embedding film after the bead embedding treatment so as to substantially improve the reflex reflection coefficient and provide the excellent light reflection effect; and the product prepared by using the glass micro-bead has the magnetic property so as to enhance the use performance, and can provide advantages of convenient use, convenient replacement and convenient washing in the application in the reflective warning labeling.

Description

technical field [0001] The invention relates to the technical field of manufacturing reflective glass beads, in particular to a method for preparing magnetic fully aluminized reflective glass beads. Background technique [0002] Glass beads are the main raw material for the manufacture of reflective materials, and can be widely used in reflective materials in roads, railways, airports, ports, ocean transportation, mines, tunnels, fire protection, urban construction and other fields. With the increase of my country's investment in infrastructure construction, the demand for glass beads is increasing, and the performance requirements for glass beads are also getting higher and higher. At present, only a few manufacturers in my country have mastered the production technology of high refractive index glass beads, and the performance of their products is very unstable, and the reflective performance still cannot meet the actual needs and market requirements. [0003] Therefore...
