[0016] A kind of preparation method of colored neon tube of the present invention, comprises the following steps:
[0017] (1) Prepare the color pigment and nitrocellulose glue according to the ratio of 100:20-100:40 (g / ml) so that the viscosity is 15-20s and the specific gravity is 1.5-2.0g / cm 3 color pigment paste;
[0018] (2) Evenly apply the prepared color pigment paste to the inner wall of the colorless glass lamp tube and dry to form the first layer of color pigment layer;
[0019] (3) Prepare fluorescent powder and nitrocellulose glue according to the ratio of 100:15-100:30 (g / ml) so that the viscosity is 10-15s and the specific gravity is 1.2-1.5g / cm 3 Phosphor paste;
[0020] (4) Apply the prepared fluorescent powder slurry evenly on the dried first layer of color pigment layer and dry to form a second fluorescent layer on the inner wall of the glass lamp tube;
[0021] (5) Install electrodes on both ends of the glass lamp tube to form a neon lamp.

[0022] Example 1: Manufacture of yellow neon tube
[0023] (1) Prepare powder slurry a. Put 100g of yellow pigment, 10ml of prepared nitrocellulose solution and 12ml of butyl acetate into a ball mill jar equipped with 250g agate balls, mill for 5 hours, pour out the material solution and stir for 40 minutes, then pass A 300-mesh sieve is used to obtain a prepared yellow pigment paste. B. Put 100g of Sanjise yellow powder, 20ml of nitrocellulose, and 16m of butyl acetate into a ball mill jar with 250g of agate balls, mill for 4 hours, pour out the slurry and stir for 30 minutes, pass through a 300-mesh sieve, and get Prepared yellow fluorescent powder paste.
[0024] (2) Powder coating: apply a layer of prepared pigment paste on the inner wall of the cleaned and dried glass tube, after it is dried, apply three primary color fluorescent powder paste, and then dry it to obtain a yellow appearance of light tubes.

[0025] Example 2: Manufacture of blue neon tubes
[0026] (1) Preparation of powder slurry a. Put 100g of blue pigment, 10ml of prepared nitrocellulose solution, and 10ml of butyl acetate into a ball mill jar equipped with 250g of agate balls, mill for 4 hours, pour out the material solution and stir for 40 minutes, then After passing through a 300-mesh sieve, the prepared powder slurry is obtained. b. Put 80g of tricolor blue powder, 15ml of nitrocellulose, and 13ml of butyl acetate into a ball mill jar with 160g of agate balls, mill for 3 hours, pour out the powder and stir for 30 minutes, pass through a 300-mesh sieve, and get Prepared blue fluorescent powder paste.
[0027] (2) Powder coating: apply a layer of prepared blue pigment paste on the inner wall of the cleaned and dried glass tube, after it is dried, apply the three primary colors of blue powder paste, and then dry it to obtain the appearance For the blue light tube.
