Problems solved by technology

The quality of the release agent affects the release rate and also affects the film formation of the capsule
Existing mold release agents generally have disadvantages such as high viscosity, small oil film distribution surface, thick coating, and large usage. After gluing, the capsules are prone to lace, and the glue is unevenly distributed on the mold, resulting in large differences in capsule particle weight. , Filling volume is not easy to control and other consequences

Embodiment Construction

[0023] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

[0024] The viscosity of the present invention is the data measured with a DV2T viscosity instrument after heating an appropriate amount of release oil to 40-45°C.

[0025] Example 1

[0026] A kind of capsule release agent of low viscosity, its preparation method comprises the following steps:

[0027] (1) Take 82 parts of white oil and 10 parts of soybean oil, pour them into a heat preservation bucket, stir and mix evenly, keep warm at 95°C for 15 minutes, and set aside;

[0028] (2) Add 8 parts of soybean lecithin and 0.5 part of stearic acid into the mixture in (1), and emulsify for 17 minutes;

[0029] (3) Pour the emulsified mixture into a heat preservation bucket, keep it warm at 95°C for 30 minutes, and then filter to obtain a release agent with a viscosity of 62mPa·s and a coefficient of static...

Abstract

The invention discloses a low-viscosity capsule mold release agent and a preparation method thereof. The low-viscosity capsule mold release agent consists of the following components in parts by weight: 80-99 parts of white oil, 0.5-20 parts of soybean lecithin, 0.1-0.5 part of stearic acid and 0.5-16 parts of soybean oil. The viscosity of the mold release agent disclosed by the invention is 50-90mPa.s, the static friction coefficient is 0.15-0.45 and is only less than a half of that of a general capsule mold release agent, and the mold release agent is excellent in lubricating effect and relatively high in capsule product mold release rate. The preparation method of the low-viscosity capsule mold release agent disclosed by the invention has the advantages of simple and convenient process, short preparation period, high production efficiency and the like, and the produced mold release agent has the advantages of small surface tensile force, wide oil film distribution area, less dosage, uniform coating and the like, and is easy to realize low-cost large-scale production.

Description

technical field [0001] The invention relates to a low-viscosity capsule release agent and a preparation method thereof, which are applied to the production of hollow capsules in the pharmaceutical industry. Background technique [0002] The production process of the hollow capsule is viscose molding, and the final product needs to be released from the mold with the help of a release agent. The quality of the release agent affects the release rate and also affects the film formation of the capsule. Existing mold release agents generally have disadvantages such as high viscosity, small oil film distribution surface, thick coating, and large usage. After gluing, the capsules are prone to lace, and the glue is unevenly distributed on the mold, resulting in large differences in capsule particle weight. , Filling volume is not easy to control and other consequences. Therefore, there is a need for a release agent with a low viscosity, a small static friction coefficient, and a wi...
