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 releasing agent and preparation method thereof, it is applied to pharmaceuticals industry Capsuleses
Produce.
Background technology
The production technology of Capsuleses is viscose glue molding, and final products need to depart from from mould by releasing agent.The demoulding
The quality impact demolding rate of agent, also can affect the film forming of capsule simultaneously.Existing releasing agent generally has that viscosity is higher, film distribution
The shortcomings of face is little, coating is thicker, usage amount is big, after viscose glue, capsule is also easy to produce lace, glue skewness on mould, leads to
The consequence such as during the different big, filling of the capsule grain method of double differences loading amount is wayward.Accordingly, it would be desirable to a kind of viscosity is relatively low, confficient of static friction is little, oily
The wide releasing agent of film distribution solves the above problems.
Content of the invention
The purpose of the present invention is for problem above, provides the glue that a kind of low viscosity, coefficient of friction are little, film distribution is wide
Capsule parting agent special.
The technical solution used in the present invention is:
A kind of low viscous capsule releasing agent is it is characterised in that be made up of following components mass fraction:
80～99 parts of white oil；
0.5～20 part of soybean phospholipid；
0.1～0.5 part of stearic acid；
0.5～16 part of soybean oil.
A kind of preparation method of low viscous capsule releasing agent is it is characterised in that comprise 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, standby；
(2) 0.5～20 part of food level soybean phospholipid, 0.1～0.5 part of stearic acid are added in the mixed liquor in (1), emulsifying
15min～20min；
(3) mixed liquor after emulsifying is poured in heat-preserving container, filter after 85～95 DEG C of insulation 25min～35min, obtain
Viscosity is 50～90mpa s, and confficient of static friction is 0.15～0.45 releasing agent.
Compared with prior art, present invention has the advantage that
(1) used in the present invention, white oil is cheap, by as the lubricant of product or releasing agent in a lot of industries,
Itself stable chemical nature and safe.
(2) used in the present invention, soybean oil has good lubricating release effect, can be big as finished product coefficient of friction
Little regulator.
(3) used in the present invention, soybean phospholipid, stearic acid have good oleophylic performance, can have as surfactant
The surface tension of the reduction white oil of effect, makes releasing agent film distribution become wide, and featheredging reduces releasing agent in process of production
Usage amount.
(4) the releasing agent viscosity of the present invention is 50～90mpa s, only general capsule class releasing agent less than half, table
Face tension force is low, film distribution is wide, oil film thickness is thin, saves releasing agent usage amount in process of production, has saved and produced into
This.
(5) releasing agent of the present invention has relatively low oil film thickness, makes capsule closer to mould, so that the size of capsule
More accurate, improve the qualification rate of product, also make residual quantity in finished product for the releasing agent and the fall of the impact to capsule quality
Low.
(6) the releasing agent confficient of static friction of the present invention is little, has very excellent lubricant effect, makes mould have higher taking off
Mould success rate, thus improve the qualification rate of product.
(7) adopt the releasing agent of the present invention, generation and the glue of capsule lace can be greatly reduced when producing capsule
Capsule wall thickness variation.
(8) preparation method of the present invention is easy, and short preparation period greatly shortens preparation time, saved and produced into
This.
Specific embodiment
With reference to specific embodiment, the present invention is described further, but the scope of the present invention is not limited only to this.
The viscosity of the present invention is all to take appropriate mould oil, is heated to 40～45 DEG C, is recorded with dv2t viscosity instrument
Data.
