[0016] A preparation method of a moisture-proof film coating agent for traditional Chinese medicine tablets, comprising the following steps:
[0017] (1) Throw vinylpyrrolidone-vinyl acetate copolymer, 5-15 centipoise hypromellose, polyethylene glycol 6000, iron oxide, titanium dioxide and talc into a high-speed mixer at a speed of 2700 rpm Mix for 0.5 to 3 minutes; the speed of the high-speed mixer is 2700 rpm, and the mixing time is 0.5 to 3 minutes.
[0018] (2) Sprinkle Tween 80 evenly on the material in the high-speed mixer, and mix at a speed of 2700 rpm for 0.5-3 minutes to make a finished Chinese medicine tablet moisture-proof film coating agent.
Embodiment 1
[0020] A preparation method of a moisture-proof film coating agent for traditional Chinese medicine tablets, comprising:
[0021] (1) Weigh 20 parts of vinylpyrrolidone-vinyl acetate copolymer, 30 parts of hypromellose of 5-15 centipoise, 600020 parts of polyethylene glycol, 803 parts of Tween, iron oxide 10 parts, 17 parts of talcum powder;
[0022] (2) Put vinylpyrrolidone-vinyl acetate copolymer, 5-15 centipoise hypromellose, polyethylene glycol 6000, iron oxide, titanium dioxide and talcum powder into a high-speed mixer, at a speed of 2700 Mix for 2 minutes at rpm;
[0023] (3) Sprinkle Tween 80 evenly on the material in the high-speed mixer, and mix at a speed of 2700 rpm for 15 minutes to prepare a moisture-proof film coating agent for traditional Chinese medicine tablets.
Embodiment 2
[0025] (1) Weigh 50 parts of vinylpyrrolidone-vinyl acetate copolymer, 10 parts of hypromellose of 5-15 centipoise, 600010 parts of polyethylene glycol, 803 parts of Tween, and 10 parts of iron oxide according to the ratio of parts by mass. 17 parts and talcum powder;
[0026] (2) Put 5-15 centipoise of hypromellose, polyethylene glycol 6000, iron oxide, titanium dioxide and talc into a high-speed mixer, and mix for 2 minutes at a speed of 2700 rpm;
[0027] (3) Sprinkle Tween 80 evenly on the material in the high-speed mixer, and mix at a speed of 2700 rpm for 15 minutes to prepare a film coating agent for Chinese medicine tablets.
[0028] Using a conventional method, a kind of moisture-proof film-coating agent for Chinese medicine tablets of Example 1 and Example 2 is made into a solution, and sprayed on the surface of the Chinese medicine core to make a moisture-proof film-coated tablet. Then carry out the moisture-proof test: use the constant temperature and humidity box...
