Problems solved by technology

[0003] However, due to the fragility of glass, there are also three problems that plague the industry: First, if the glass bulb is in contact with other glass or hard objects during the transfer process, it is extremely easy to scratch or even break, and the lighter will affect The appearance of the finished product will cause the glass bulb to be scrapped, so the packaging of the glass bulb is also a test; second, if the glass bulb that leaves the packaging box is accidentally dropped during the transfer process, it is extremely easy to break, and the glass fragments splashed and scattered are used. Third, some users who do not operate in accordance with the specifications find that although the glass is broken, the wick of the exposed bulb is still usable after being powered on, and they continue to use it rashly, resulting in a great electric shock safety hazard

Effect test

Embodiment 1

[0026] Protective coating of the present invention is a kind of non-water-soluble coating, and its preparation takes the following components by weight parts:

[0027] Alcohol-soluble resin 30-50 leveling agent 0.1-1 alcohol or ether solvent 30-85

[0028] Stir and mix the above components evenly to obtain a protective coating.

Embodiment 2

[0030] A method for protecting glass lamps, the specific steps are as follows:

[0031] First obtain the protective coating according to Example 1, dip-coat the protective coating on the surface of the glass lamp, and then dry it naturally at 25°C for 30 minutes to volatilize the solvent in the protective coating on the surface of the glass lamp, that is, obtain transparent protection on the surface of the glass lamp. The surface roughness of the protective film and the roughness deviation of the original glass substrate surface is 5 microns, the light transmittance of the protective film is 95%, and the refractive index is 1.44. The protective film is tightly wrapped on the surface of the glass lamp without peeling off. The lamps treated with the protective film rub against each other without any scratches on the glass surface.

Embodiment 3

[0033] A method for protecting glass lamps, the specific steps are as follows:

[0034] First obtain the protective coating according to Example 1, apply the protective coating to the surface of the glass lamp by brushing, and then dry it in an electric oven at 120°C for 0.5 minutes to volatilize the solvent in the protective coating on the surface of the glass lamp, that is, obtain a transparent coating on the surface of the glass lamp. Protective film, the roughness deviation between the surface roughness of the protective film and the roughness of the original glass substrate surface is 50 microns, the light transmittance of the protective film is 85%, and the refractive index is 1.50. The protective film is tightly wrapped on the surface of the glass lamp without peeling off. Two lamps treated with a protective film rub against each other without any scratches on the glass surface.

Abstract

The invention relates to a method for protecting a glass lamp, and also discloses a formula of protective coating. The method comprises the following steps: treating the surface of the glass lamp with the protective coating through film coating, and then volatilizing a solvent in the protective coating on the surface of the glass lamp by a drying process to obtain a transparent protective film on the surface of the glass lamp, wherein the protective film can prevent the glass lamp from being scratched or directly collided in the transporting and transferring processes; even if the glass lamp is ruptured accidentally, the glass lamp can be completely enwrapped by the protective film and glass fragments are not exposed, so that injuries to a user are avoided.

Description

technical field [0001] The invention relates to the lighting field of glass lamps, in particular to a method for protecting glass lamps. Background technique [0002] There are several reasons for using a large number of glass lamps in the lighting field: 1. The glass material has excellent light transmittance; 2. The source of glass material is rich, the processing technology is mature, and it can be made into any shape; 3. Glass is an insulator during use. Electric shock can be avoided. [0003] However, due to the fragility of glass, there are also three problems that plague the industry: First, if the glass bulb is in contact with other glass or hard objects during the transfer process, it is extremely easy to scratch or even break, and the lighter will affect The appearance of the finished product will cause the glass bulb to be scrapped, so the packaging of the glass bulb is also a test; second, if the glass bulb that leaves the packaging box is accidentally dropped d...
