Problems solved by technology

The other is a non-metallic dielectric film, which uses silicon monoxide SiO and zinc sulfide ZnS, and is continuously and alternately evaporated in a vacuum state. The disadvantage is that a complete film cannot be deposited at a time.
like figure 1 As shown, the existing lamp cup includes a cup body 11′ in the shape of a conical truncated cup and a cup bottom 12′ in a cylindrical shape. Due to the shape of the cup, the film layer can only be coated on the cup body 11′, while the bottom of the cup 12' cannot be plated, this is because the inner diameter of the bottom of the cup is limited, the probability of material molecules entering is too low, even if a small amount enters, the crystallization film cannot be completed
[0004] In addition, most of the existing coatings are carried out by a vacuum process, such as the invention patent "Lamp Cup Magnetron Sputtering Coating and Surface Vacuum Hardening Protective Layer Continuous Production Process" disclosed by the publication number CN102776482A. However, this type of invention requires a lot of equipment. , and the price is expensive, causing the price of the product to be high

preparation example Construction

[0052] Correspondingly, the present invention also provides a method for preparing a pressed glass lamp cup, comprising:

[0053] (1) Mix component A, component B and thinner to obtain an insulating coating. After mixing component A, component B and diluent, it is also necessary to perform bubble removal treatment on the insulating coating to avoid bubbles during film formation.

[0054] (2) Dip or spray the insulating paint on the inner surface of the pressed glass lamp cup body, and then perform leveling treatment.

[0055] Dip coating and spray coating adopt different methods for different product specifications and comprehensive output efficiency. For example, when it is applied to PAR lamps, the spray coating process is used; when it is applied to MR16, GU10 and other spotlights, the dip coating process is used.

[0056] (3) drying the glass;

[0057] Specifically, step (3) includes:

[0058] First dry in the low temperature zone of 50-70 degrees for 2-7 minutes; then ...

Embodiment 1

[0065] (1) Production component A: 5% pyromellitic dianhydride, 35% diaminodiphenyl ether, 40% organosilane, 5% 3-aminopropyltrimethoxysilane, β-(3,4- Epoxycyclohexyl) ethyltrimethoxysilane 5%, ethyl orthosilicate 5%, ethyl acetate 5% are mixed according to the proportion;

[0066] (2) Making component B: mixing 60% of siloxane oligomer, 20% of metal oxide catalyst, and 20% of structure control agent according to the proportion;

[0067] (3) Mix component A and component B at a ratio of 100:5 to obtain an insulating coating;

[0068] (4) Dip-coat the insulating paint on the inner surface of the pressed glass lamp cup body, and then perform leveling treatment;

[0069] (5) Dry the glass in a low temperature zone of 50 degrees for 5 minutes; then dry it in a medium temperature zone of 90 degrees for 6 minutes; finally dry it in a high temperature zone of 140 degrees for 10 minutes;

[0070] (6) The glass is forcedly air-cooled until it reaches normal temperature.

Embodiment 2

[0072] (1) Production component A: 10% pyromellitic dianhydride, 25% diaminodiphenyl ether, 30% organosilane, 5% 3-aminopropyltrimethoxysilane, β-(3,4- Epoxycyclohexyl) ethyl trimethoxysilane 10%, ethyl orthosilicate 10%, ethyl acetate 10% mixed according to the proportion;

[0073] (2) Preparation of component B: mix 70% of siloxane oligomer, 15% of metal oxide catalyst, and 15% of structure control agent according to the proportion;

[0074] (3) Mix component A and component B at a ratio of 100:7 to obtain an insulating coating;

[0075] (4) Dip-coat the insulating paint on the inner surface of the pressed glass lamp cup body, and then perform leveling treatment;

[0076] (5) Dry the glass in a low temperature zone of 60 degrees for 4 minutes; then dry it in a medium temperature zone of 100 degrees for 5 minutes; finally dry it in a high temperature zone of 150 degrees for 8 minutes;

[0077] (6) The glass is forcedly air-cooled until it reaches normal temperature.

Abstract

The invention discloses a pressed glass lamp cup. The pressed glass lamp cup comprises a cup body and an insulating film arranged on the inner surface of the cup body. The insulating film is arrangedon the inner surface of the cup body through insulating paint, and the coating range of the insulating film covers the whole inner surface from a cup opening to a cup bottom. The insulating paint comprises a component A and a component B, and the mixing ratio of the component A to the component B is 100:(1-10). Correspondingly, the invention further provides a preparation method of the pressed glass lamp cup and a lamp adopting the pressed glass lamp cup. According to the pressed glass lamp cup, the insulating film arranged on the pressed glass lamp cup can be formed at a time and is uniformlyand completely smeared on the whole inner surface from the cup opening to the cup bottom, and the inner electroconductive problem is solved.

Description

technical field [0001] The invention relates to the field of lamp cups, in particular to a pressed glass lamp cup and a preparation method thereof. Background technique [0002] Existing lamp cups are generally made of a transparent or translucent material to place a light source so that the light can be projected softly. However, accessories such as power supply, light source, and radiator need to be loaded into the inside of the cup body. People can directly watch the accessories inside the cup body, which is very unsightly. In order to make it artistic and ornamental, it needs to be coated on the cup body. [0003] Existing coatings generally include two types: one is a conductive metal film, such as an aluminum film, etc., the aluminum film is relatively simple in the coating process, and can be coated with a complete film at a time (that is, one-time molding). It is required to extend from the mouth of the cup to the entire inner surface of the bottom of the cup. The...
