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
The present invention relates to a kind of low viscous Capsule demold agent and preparation method thereof, be applied to the production of pharmaceuticals industry Capsules.
Background technology
The production technology of Capsules is that viscose glue is shaping, and final products need to depart from from mould by releasing agent.The quality influence demolding rate of releasing agent, also can affect the film forming of capsule simultaneously.The consequences such as existing releasing agent generally has viscosity compared with the shortcoming such as high, film distribution face is little, coating is thicker, use amount is large, and after viscose glue, capsule easily produces lace, glue skewness on mould, and when causing different large, the filling of the capsule grain method of double differences loading amount is wayward.Therefore, a kind of viscosity is needed to solve the problem compared with low, that confficient of static friction is little, film distribution is wide releasing agent.
Summary of the invention
The object of the invention is for above problem, the capsule parting agent special that a kind of low viscosity, coefficient of friction are little, film distribution is wide is provided.
The technical solution used in the present invention is:
A kind of low viscous Capsule demold agent, is characterized in that being made up of following constituent mass number:
White oil 80 ~ 99 parts;
Soybean lecithin 0.5 ~ 20 part;
Stearic acid 0.1 ~ 0.5 part;
Soybean oil 0.5 ~ 16 part.
A preparation method for low viscous Capsule demold agent, is characterized in that comprising the following steps:
(1) 80 ~ 99 parts of food-level white oils, 0.5 ~ 16 portion of soybean oil are poured in heat-preserving container, be uniformly mixed, in 85 ~ 95 DEG C of insulation 15min ~ 20min, for subsequent use;
(2) 0.5 ~ 20 part of food level soybean phosphatide, 0.1 ~ 0.5 part of stearic acid are added in the mixed liquor in (1), emulsification 15min ~ 20min;
(3) pour in heat-preserving container by the mixed liquor after emulsification, filter after 85 ~ 95 DEG C of insulation 25min ~ 35min, obtaining viscosity is 50 ~ 90mPas, and confficient of static friction is the releasing agent of 0.15 ~ 0.45.
Compared with prior art, the present invention has following advantage:
(1) white oil used in the present invention is cheap, by as the lubricant of product or releasing agent in a lot of industry, and itself stable chemical nature and security is high.
(2) soybean oil used in the present invention has good lubricating release effect, can as the conditioning agent of finished product coefficient of friction size.
(3) soybean lecithin used in the present invention, stearic acid have good oleophylic performance, can effectively reduce white oil surface tension as surfactant, and make releasing agent film distribution become wide, featheredging, reduces releasing agent use amount in process of production.
(4) releasing agent viscosity of the present invention is 50 ~ 90mPas, and below the half only having general capsule class releasing agent, surface tension is low, film distribution is wide, oil film thickness is thin, saves releasing agent use amount in process of production, has saved production cost.
(5) releasing agent of the present invention has lower oil film thickness, makes capsule more press close to mould, thus the size making capsule is more accurate, improves the qualification rate of product, also makes the residual quantity of releasing agent in finished product and reduces the impact of capsule quality.
(6) releasing agent confficient of static friction of the present invention is little, has very excellent lubricant effect, makes mould have higher demoulding success rate, thus improves the qualification rate of product.
(7) adopting releasing agent of the present invention, significantly can reduce generation and the capsule wall thickness variation of capsule lace when producing capsule.
(8) preparation method of the present invention is easy, and manufacturing cycle is short, shortens preparation time greatly, has saved production cost.
