Abstract
A fluorescent powder coating liquid is prepared from fluorescent powder and inorganic adhesive which contains nm-class high-viscosity silica sol and optional solvent, strengthening agent, disperser, defoaming agent, plasticizer and surfactant through mixing and ball grinding. With said coating liquid, high-temp baking step is omitted, saving energy and avoiding the sodium releasing from glass at high temp, which can improve the light efficiency and quality of fluorescent lamp.
Description
The present invention relates to the fluorescent material paint-on technique of fluorescent tube bulb, belong to the fluorescent tube bulb production technical field.
Need in the fluorescent tube bulb production fluorescent material firmly and equably is coated on the inwall of Glass tubing (or glass bulb).In existing luminescent lamp coating processes, at first mixing and ball milling such as fluorescent material, binding agent, solvent, strengthening agent, dispersion agent, defoamer and softening agent are become phosphor slurry, adopt certain mode that phosphor slurry is coated on the internal surface of glass-tube (glass bulb) then.Because binding agent adopts organic soluble polymer binding agent (for example nitro-cotton binding agent) and water-soluble polymers binding agent (for example polyvinyl alcohol), thereby requisite high temperature roasted tube technology is together arranged in the manufacturing process of luminescent lamp, so that binding agent is decomposed from coating.High temperature roasted tube technology has not only been wasted a large amount of energy, and the sodium high temperature in the glass is disengaged, and the optical efficiency of fluorescent tube is descended.
The objective of the invention is at the deficiencies in the prior art, a kind of inorganic adhesive fluorescent powder coating liquid and compound method thereof that does not need high temperature roasted tube technology in fluorescent tube is made is provided, thereby help improving the optical efficiency of fluorescent tube, minimizing equipment, operator, plant area and power consumption are shortened the production cycle and are reduced cost.
Inorganic adhesive fluorescent powder coating liquid of the present invention can be made up of fluorescent material and binding agent, is characterized in that binding agent adopts mineral compound nanometer glue (or claiming nano paint).Nanometer glue is that (viscosity can be greater than 0.015NS/m for a kind of high viscosity
2) silicon sol, it can add one or more reagent that can increase viscosity (for example increasing a certain amount of sodium ion or potassium ion) and constitute in ordinary silicon colloidal sol.According to the needs of viscosity, can in fluorescent powder coating liquid, add suitable quantity of water (for example deionized water) as solvent, the weight percent of fluorescent material, binding agent and water can be (40～5%), (55～90%), (0.5～50%).Also can in fluorescent powder coating liquid, add an amount of strengthening agent, dispersion agent, defoamer, softening agent or tensio-active agent according to actual needs.
The compound method of inorganic adhesive fluorescent powder coating liquid of the present invention can prepare the nanometer glue of certain viscosity at normal temperatures, slowly pour in the ball grinder that fills a certain amount of fluorescent material, add quantitative ball milling ball mixing and ball milling again and form, the weight percent of nanometer glue and fluorescent material is (55～90%) and (45～10) %.
The present invention compared with prior art, have easy to use, cohesiveness good and the light efficiency advantages of higher, particularly in making luminescent lamp technology, do not need the high temperature roasted tube, both saved the energy, improved the fluorescent tube optical efficiency again.Weight percent by adjusting nanometer glue and fluorescent material is the caking ability of nanometer glue when, realize the needed thickness of phosphor powder layer, also can further improve the outward appearance and the quality of phosphor powder layer, thereby help improving the optical efficiency and the quality of luminescent lamp by adding proper amount of solvent, strengthening agent, dispersion agent, defoamer and softening agent etc.
The present invention can realize according to the scheme of following examples.Binding agent nanometer glue can increase an amount of sodium ion or potassium ion in ordinary silicon colloidal sol, reach needed caking ability.
Embodiment 1: the weight percent of nanometer glue and fluorescent material is that the proportioning ball milling of (55～90) % (for example 70%) and (45～10) % (for example 30%) forms.
Embodiment 2: the weight percent of nanometer glue, fluorescent material and deionized water (or distilled water) is respectively (55～90) % (for example 65%), (40～5) % (for example 30%) and (5～40) % (for example 5%) and the proportioning ball milling forms.
Embodiment 3: the proportioning ball milling that the weight percent of nanometer glue, fluorescent material, deionized water (or distilled water) and strengthening agent (triethyl phosphate or calcium pyroborophosphate) is respectively (55～90) % (for example 66%), (45～10) % (for example 30%), (5～40) % (for example 3%) and (0.5～2) % (for example 1%) forms.
