Description
The present invention relates to the wrapping wax shell of traditional Chinese medicine pill.
The wax shell of traditional Chinese medicine pill be the protection honeyed bolus moisten, soft, prevent that honeyed bolus from making moist, go mouldy, damaging by worms and make it never lose the important inner packaging material of drug effect.Traditional honeyed bolus packaging wax shell is to adopt paraffin, beeswax as the manual wax shell prescription that hangs wax, there is poor, the easy shortcoming of embrittlement of resistance to low temperature in the wax shell of being made by this prescription, in storage and handling process,, easily cause breaking of larger proportion owing to run foul of each other.Raising along with the automation of industry level, wax shell wrapping machine place in operation, for satisfying the requirement of mechanical-moulded wax shell, adopt at present paraffin, ceresine, low molecular polyethylene, petroleum ointment compositing formula as machine-processed wax shell, but because ceresine is the compound of parabolic hydrocarbon and poly-methylene, includes and be difficult to the arene compound removed on a small quantity, though can improve the embrittlement of wax shell, but microtoxicity is arranged, be unsuitable for doing packing with food, medicine direct contact.
The objective of the invention is to: by adding thermoplastic polyethylene, EVA and tackifier rosin, plasticizer, castor-oil plant wet goods replace the improvement of honeybee wax And to the wax prescription, solve manual low-temperature embrittleness problem of hanging wax wax shell, reduce its cost significantly; Add thermoplastic base resin EVA, EAA, tackifier, rosin, plasticizer, castor-oil plant wet goods replacement ceresine, the toxicity problem of settlement mechanism wax shell.
Prescription of the present invention and preparing process:
1, the manual wax prescription that hangs:
| Material name | Specification | Consumption (percentage by weight) |
| Paraffin | Packaging for foodstuff level (meeting the SY1857-80 standard) | 60－80 |
| Material name | Specification | Consumption (percentage by weight) |
| EVA (or EEA) resin | VA＝28－30％ | 1-10 |
| Poly-vinyl resin | Industrial grade | 0-6 |
| Rosin | Industrial grade | 15-20 |
| Castor oil | Medical | 3-5 |
| Low molecular polyethylene | Industrial grade | 1-5 |
(annotate: each weight percentages of components sum should be 100%)
EVA(or EEA) resin is a kind of thermoplastic base resin of copolymerization, fusion index 20-300 has good flexibility, elasticity as the rubber, its resistance to ag(e)ing and ultra-violet resistance are good, have the characteristic of antifungi growth, nontoxic, and certain intermiscibility is arranged with paraffin.
Poly-vinyl resin is a thermoplastic base resin, and certain rigid is arranged, and is nontoxic, low temperature resistance is superior, and the low-temperature embrittleness temperature reaches-80 ℃, and the mixed boundless and indistinct pancreas Yin of the benzyl institute forget of this resin and paraffin reveals the magpie spit of fland
Adding above two kinds of resins can increase the low temperature resistance of wax shell, but addition too much can raise the cost, and increases viscosity, hangs wax and is difficult for evenly.When adding the resin total amount when surpassing 16%, therefore the obvious retrogradation of wax liquid is taken all factors into consideration and should be met performance requriements, opens the wax shell again easily, and resin adds total amount must not be greater than 16%.
Rosin: vitreous glazing shape brittle substance, it is the compound of various kinds of resin acid, metamer more than 9 kinds is arranged, main component is an abietic acid, and it not only has good intermiscibility, and contains the carboxyl of high polarity, dissolubility is widely arranged, with resin good intermiscibility being arranged also, is good tackifier, can improve the crystallinity of paraffin.Add rosin wax body hardness is reduced, low temperature resistance improves.But consider the color of wax shell, add 25% beginning flavescence, therefore maximum consumption must not surpass 20%.
Castor oil: be a kind of plasticizer, can improve the low-temperature embrittleness of paraffin, the viscosity when adjusting fusion adds the low temperature resistant crumbliness that castor oil can strengthen the wax body, but the wax fluid viscosity becomes big, and curing rate is slack-off, so the maximum consumption of castor oil is 5%.
Low molecular polyethylene: be a kind of dibutyl phthalate, can change the crystallinity of paraffin, increase the toughness of paraffin.Its structure is similar to paraffin, and intermiscibility is good, is easy to the wax casing forming.But consumption surpasses at 5% o'clock, can make wax shell surfaces of tacky, is 1-5% so select amount ranges.
With EVA(or EEA) resin, PE resin, rosin, castor oil and low molecular polyethylene be used the replacement beeswax, both can solve the easy embrittlement problem of wax shell, and cost is reduced.
Preparing process:
After weighing according to prescription, the paraffin of EVA resin, PE resin and 1/5 total weight is put into heating container to heat up, under 140-160 ℃, make the resin fusion, start stirring, and add the paraffin of remaining 4/5 total weight, be stirred to fine melt, add low molecular polyethylene, castor oil more successively, add rosin at last.This process is generally carried out under 120-130 ℃, treat fine melt after, discharging is filtered, and is cooled to 80-90 ℃, this filtrate promptly can be used for the manual wax that hangs and makes honeyed bolus packing wax shell, also can filter thoroughly cooling of back in discharging, make wax stone, interim heating and melting when to be used.
2, machine-processed wax prescription
(annotate: each weight percentages of components sum is 100%)
EVA(or EEA) resin: be a kind of thermoplastic base resin of copolymerization, fusion index 20-300 has good flexibility, the elasticity as the rubber, its ageing-resistant and ultra-violet resistance is good, have the characteristic of antifungi growth, nontoxic, and certain compatibility is arranged with paraffin.
The EAA resin: the themoplasticity copolymer resins has good heat stability and environmental stress crack resistance, nontoxic.
Adding above two kinds of resins can increase the low temperature resistance of wax shell, but addition too much can raise the cost, and increases viscosity, make machine-processed wax shell housing inhomogeneous, when adding resin total amount surpasses 6%, the obvious retrogradation of wax liquid, therefore take all factors into consideration, the adding total amount of resin must not be greater than 6%.
Beeswax: be impalpable structure, can be used as the plasticizing substance of paraffin.Increase with beeswax increases to the toughness reinforcing degree of paraffin, but beeswax adds too much, and the rigidity of wax body and heat stability will variation, and the beeswax price is more expensive, so the maximum consumption of beeswax can not surpass 30%.
Rosin: vitreous glazing shape brittle substance, it is the compound of various kinds of resin acid, metamer more than 9 kinds is arranged, main component is an abietic acid, and it not only has good intermiscibility, and contains the carboxyl of high polarity, dissolubility is widely arranged, with resin good intermiscibility being arranged also, is good tackifier, can improve the crystallinity of paraffin.Add rosin the reduction of wax body hardness, low temperature resistance are improved, but consider the color of wax shell, add 25% beginning flavescence, therefore maximum consumption must not be above 20%.
Cooperation with EVA, EAA resin, beeswax and rosin replaces ceresine, and the low temperature resistant embrittlement that can improve machine-processed wax shell effectively makes wax body avirulence.
Preparing process:
After weighing according to prescription, the paraffin of EVA resin, EAA resin and 1/5 total weight is put into heating container, intensification, under 140-160 ℃, make the resin fusion, start stirring, and add the paraffin and the beeswax of remaining 4/5 total weight, and be stirred to fine melt, add low molecular polyethylene, petroleum ointment more successively, add rosin at last, this process is generally carried out under 120-130 ℃, treat fine melt after, discharging is filtered, be cooled to 80 ℃-90 ℃, this filtrate promptly can be used for machine-processed wax shell.Also can after filtering, discharging thoroughly cool off, make wax stone, interim heating and melting when to be used.
