Description
Technical field
The present invention relates to the preparation method of a kind of medical packing paper Cypres, belong to Cypres technology of preparing neck
Territory.
Background technology
Along with gradually integrating with of China and International Packaging, the packing instructions to curable product uprise increasingly, simultaneously take account of
Requirement to environmental conservation, praises highly paper-plastic stick in the world, moulds packaged form with paper generation.And Medical paper bag is exactly a kind of satisfied existing
The product required for medical package, it typically uses and plastic sheeting is compound makes, and has and seals the spy that reliable, heat-sealing is easily torn
Point.This product is applicable to the Medical treatment devices such as glove, gauze, cotton balls, swab stick, mask, conduit, operating equipment, dental instrument, syringe
Tool is packed, and is the most relatively commonly used, and domestic demand is the most increasing.The manufacture of medical disinfecting coated paper envelope is
The glue application layer being made raw material by the High Temperature High Pressure of Bag Making Machine is bonded with thin film, thus reaches good seal, Jing Guobiao
The paper of face applying glue needs have certain air permeability, the entrance of sterilizing factor during to meet sterilization, surface in sterilization process
Sizing agent must not stick on packing material destroy packing material health, require in use paper have good surface strength and
Heat-seal strength, thus ensure suitable bonding force when medical package paper bag is peeled off and peel off the absolute cleanliness at interface.Pin
Be accomplished by selecting special heat molten type Cypres to these features of Medical paper bag so that product meet good airproof performance,
Do not glue suitable and that paper can not be inter-adhesive with thin film when the peeling off performance requirement of medical apparatus and instruments, heat seal strength.Current is medical
Packaging bag typically uses and is coated with a circle adhesive in the side of medico paper around edge, is then covered by thin film, heat pressure adhesive, cuts,
Thus forming paper bag, reserved to put into packing material during hot pressing, sealing has only to open at one end on heat seal edge banding machine
Seal, as long as peeling off at paper bag opening end can open from two layers of paper bonding place during use.
Be presently used for medical packing paper Cypres generally exist Cypres in sterilization process be easily adhered bag
Destroying packing material health on dress thing, paper is inadequate with the heat seal strength of thin film, causes paper bag to seal insecure, and paper when peeling off
Open and be not completely separated with thin film, cause paper bag damaged or paper fibre glues.
Summary of the invention
The technical problem to be solved: generally there is sterilization process for current medical packing paper Cypres
Middle Cypres is easily adhered on packing material destruction packing material health, and paper is inadequate with the heat seal strength of thin film, causes paper
Bag seals insecure, and when peeling off, paper is not completely separated with thin film, causes paper bag breakage or paper fibre to glue asking of
Topic, it is provided that the preparation method of a kind of medical packing paper Cypres, first Xanthomonas campestris is carried out cultivating, sending out by the present invention
Obtain the supernatant containing xanthan gum after ferment, after fresher Os Bovis seu Bubali being carried out, rise with the methane liquid one after filtering
Ferment, then collects fermentation liquid and carries out decolouring with activated carbon, obtain filtrate after remove impurity, then mistake after being pulverized by zinc oxide etc.
Sieve, obtains mixed-powder, finally with auxiliary agent together high-speed stirred, the supernatant containing xanthan gum, filtrate etc. is obtained medical package
Paper Cypres.Sizing agent prepared by the present invention solves Cypres in sterilization process and holds hidden sticking on packing material
Problem, uses the paper bag prepared of sizing agent of the present invention, and paper is high with the calorific intensity of thin film, good airproof performance, during stripping paper with
Thin film can be kept completely separate, and does not results in that paper bag is damaged or paper fibre glues the problem, medical through Cypres applying glue
Wrapping paper has certain air permeability, resistance to water, good surface strength and paper adhesion.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
(1) 20～30g starch, 3～5g sodium nitrate, 2～4g potassium dihydrogen phosphate, 0.4～0.6g magnesium sulfate, 6～8g Fructus Citri Limoniae are weighed
Acid and 800～1000mL deionized waters, stirring is placed in sterilization tank, in 100～110 DEG C of sterilizings 5～10min, is cultivated
Base, is inoculated into Xanthomonas campestris in culture medium by inoculum concentration 8～10%, is subsequently transferred in incubator, 30～40 DEG C, 120
～cultivate 2～3 days under 130r/min, it is subsequently placed in centrifuge, under 1200～1300r/min, is centrifuged 20～30min, collects
Supernatant, i.e. Xanthomonas campestris bacterium solution；
(2) 30～40g starch, 6～8g peptone, 2～4g sodium nitrate and 800～1000mL deionized waters are weighed successively, stirring
It is transferred to after Jun Yun in sterilization tank, in 100～110 DEG C of sterilizings 10～20min, obtains fermentation medium, be subsequently transferred to fermentation
In tank, after fermentation medium temperature is down to 30～40 DEG C, takes 200～300mL above-mentioned Xanthomonas campestris bacterium solution and join fermentation
In tank, 30～40 DEG C of bottom fermentations 3～4 days, treat that fermentation ends is warming up to 100～110 DEG C, stir 5～10min, collect subsequently
Fermentation liquid, is placed in centrifuge, is centrifuged 30～40min under 6000～7000r/min, collects supernatant, standby；
(3) weigh 200～300g fresh Os Bovis seu Bubalis, be washed with deionized clean, be subsequently placed in fermentation tank, take methane liquid mistake
Filter, collect filtrate, take 1～2L filtrate and join in fermentation tank, control temperature at 30～40 DEG C, sealed fermenting 2～3 days, fermentation
Terminate, be warming up to 100～110 DEG C, stir sterilizing 20～30min, the Os Bovis seu Bubali after fermentation is taken out, collects fermentation liquid, be placed in
In centrifuge, under 5000～6000r/min, it is centrifuged 30～40min, collects supernatant, supernatant is joined in beaker, then
Add 2～4g activated carbons, stand 1～2h, filter, obtain filtrate, standby；
(4) weigh 3～5g zinc oxide, 2～4g carboxymethyl cellulose, 6～8g calcium carbonate to join in pulverizer and pulverize, mistake
100～200 mesh sieves, obtain mixed-powder；
(5) count by weight, weigh 40～50 parts of standby supernatant of step (2), filter that 20～30 parts of steps (3) are standby
Liquid, 5～8 parts of above-mentioned mixed-powders, 3～5 parts of sodium stearates, 1～3 part of dodecylbenzene sodium sulfonate, 1～3 part of tin dilaurate two
Butyl tin joins in blender, stirs 2～3h, obtain medical packing paper Cypres under 10000～12000r/min.
The application process of the present invention: Cypres prepared by a circle present invention is smeared by the side edge at medico paper,
Then thin film is covered on the medico paper scribbling sizing agent, under 150～160 DEG C, 4～6kPa, then seal 3～5s, reserve
While as sealing, forming paper bag, then packing material being loaded in paper bag, then carry out sealing by open at one end, use
As long as time paper bag opening end from two layers of paper bonding place peel off can open.
The present invention is compared with additive method, and Advantageous Effects is:
(1) sizing agent prepared by the present invention solves the hidden problem sticked on packing material of Cypres appearance in sterilization process,
Using paper bag prepared by the sizing agent of the present invention, paper is high with the calorific intensity of thin film, good airproof performance, paper and thin film energy during stripping
Enough it is kept completely separate, does not results in paper bag breakage or paper fibre glues the problem；
(2) medical packing paper through the Cypres applying glue of the present invention has certain air permeability, resistance to water, good surface
Intensity and paper adhesion；
(3) the main preparation process of the present invention is simple, required low cost.
