A kind of packaging of the medical sterilization based on serigraphy coating technique, utilize adhesive and auxiliary agent, the solvent of allotment, by screen printing forme, adhesive is coated in sheet-fed surface, then gluing paper non-with another is colded pressing together with adhering and solidifying by machine of colding pressing, it is made to become bag, entirety is put into pressuresteam sterilization instrument high-temperature sterilization again, when making finished product reach use, glue-line is peeled off clean, and paper fiber can not be drawn out of.
The mesh number of the screen printing forme of the gluing employing of described screen printing forme selects 200 orders, and material is nylon wire, and spread is 24.928 ~ 67.343g/m
2.
The allotment of described adhesive and auxiliary agent, solvent: adhesive
:auxiliary agent
:solvent=100
:(0.2 ~ 0.5)
:(0.4 ~ 1), wherein, solvent is alcohol solvent.
Described adhering and solidifying of colding pressing adopts normal temperature cure mode, leaves standstill adhesive solidification after 10 minutes at normal temperatures.
In described pressuresteam sterilization instrument, high-temperature sterilizing process Selecting parameter works 40 minutes under 134 DEG C of sterilizing programs, and sterilizing terminates.
The invention has the beneficial effects as follows:
1 pair of silk screen coating technique parameter is studied, and determines the matching of the parameters such as screen printing forme mesh number, spread and other relevant parameters.
The various water soluble adhesive used in 2 pairs of silk screen coating techniques and various auxiliary agent, solvent are analyzed and researched, and finally determine the proportion relation of different types of water soluble adhesive, auxiliary agent and solvent the best, guarantee the quality of medical sterilization packaging adhesive.
The various medical sterilization packaging paper used in 3 pairs of medical sterilization packaging coating techniques are analyzed and researched, and determine the matching of different paper and silk screen gluing and related process parameters.
4 pairs of medical sterilization packaging coating technique parameters are studied, and determine curing rate, the matching of the parameter such as sterilising temp and time and other relevant parameters.
Therefore, the present invention realizes medical sterilization packaging coating technique by screen printing mode on paper material surface, solves when peeling off in medical sterilization packaging and easily occurs the problems such as paper fiber extraction on paper material surface.The inventive method is utilized to improve the sticky stickiness energy of medical sterilization adhesive at special dimension.
