Abstract
By the tackiness agent that EVA resin, ester gum, oxidation inhibitor, stearic acid, silicone oil and solvent are made, put into the coating machine storagetank of repacking, coat on the paper, by regulate the film thickness that two between centers clearance control tackiness agent form on paper.Dry, cut, vacuum-drying removes residual trace solvent, promptly gets medical gluing ventilating paper, can be applicable to sealing of medical device package plastics bag, box or case, significantly improves the sterilisation effect of oxyethane steam to medicine equipment.
Description
The invention relates to medical gluing ventilating paper and preparation technology thereof, particularly relate to a kind of gluing ventilating paper and preparation technology thereof that medical device package plastics bag, box or case seal that be mainly used in.
In recent years, the Dispoable medical apparatus is replacing traditional glass medical equipment gradually.This is because the use of Dispoable medical apparatus can make the possibility of cross infection significantly reduce, and uses disposable syringe or infusion set to make patient to their wholesomeness the sense of security arranged especially, has also alleviated medical personnel's cleaning and disinfection simultaneously.Yet the Dispoable medical apparatus must be through strict sterilization when dispatching from the factory, so packing bag must have and can see through the oxyethane steam, can stop dust and bacterium etc. to enter function in it again.The packing plastics bag that uses is composited by two layers of plastics film and certain thickness is arranged at present, after the medicine equipment of packing into the sealing, in the oxyethane steam that the carries out disinfection bag more difficult to get access.Present domestic sterilization is with the pure ethylene oxide steam disinfection, also difficult effusion the after minute quantity oxyethane steam enters in the bag, and the residual ethylene oxide in the plastics bag is more, influences the use of Dispoable medical apparatus.
At above-mentioned situation, the present invention is intended to solve medical device package bag, box or case oxyethane steam in sterilization and can enters smoothly, can overflow smoothly again, can intercept the problem that dust and bacterium enter again simultaneously.
The present invention can seal by putting in medical device package bag, box or case, can solve the problems referred to above by gas-pervious medical gluing ventilating paper again.
Medical gluing ventilating paper is made up of common paper and tackiness agent two parts.Described common paper is domestic ordinary white or painted cylinder coil paper or flat stacker, tackiness agent has polyethylene one acetate ethylene copolymer (EVA) resin, ester gum by different content, stearic acid, dimethyl silicone oil, oxidation inhibitor are (as 2,6-di-tert-butyl-4-methylphenol etc.), compositions such as silicone oil and solvent.
The structural formula of EVA resin is
, common n＞m.Owing to have in the molecule
Structure, according to the similar person principle that mixes, the EVA resin preferably with polyethylene
Polypropylene
Deng the film bonding that close molecular structure is arranged, and in the EVA molecular resin
M, promptly the molecular chain of vinyl acetate between to for plastic (VA) has hydrophilic lipotropy.Therefore, water, oxyethylene isopolarity solvent can reach the disinfectant purpose by penetrating eva film, enter in plastics bag, box or the case through paper with combining of vinyl acetate between to for plastic.
After single tackiness agent coating by EVA resin and solvent composition, the adhesive power of the adhesion of film of its formation on paper is less.With Plastic film Bag, box or case bonding after, the paper upper film will change soon to adhere on the plastics film and separates with paper, does not reach disposable purpose of sealing.In order to increase the adhesive power of eva film and paper, can add rosin or terpine resin usually, but the rosiny softening temperature is lower, feel is more sticking, and air-permeable paper must do not locate below 50 ℃ bonding voluntarily.Therefore, it is higher to use softening temperature instead, the ester gum that meets food hygienic standard, make the adhesive power of eva film and paper that increase largely be arranged, substantially after reaching air-permeable paper and film and tearing packing bag after bonding, paper is destroyed substantially, does not recover former state, reached the purpose of really sealing, to the user a kind of this kind medical equipment being arranged is to use for the first time and not by the used sense of security repeatedly.
But in order to make row produce serialization, must make plate-like or tubular coil paper or flat stacker to air-permeable paper, therefore air-permeable paper be had adherent requirement mutually between air-permeable paper after the long-term storage.For this reason, added be applicable to food product pack do not influence not only ventilation property but also surface lubricant such as nontoxic stearic acid, rather than add unfavorable gas-pervious surface lubricant such as paraffin class.Also added the oxidation inhibitor (as 2,6-di-tert-butyl-4-methylphenol etc.) that is applicable to food product pack in the component, aging with eva film after preventing the air-permeable paper long storage.
Medical gluing ventilating paper is made up of following compositions usually: EVA resin 5～15%(is 15%VA 20～80% wherein, 28%VA 20～80%, 40%VA 10～20%), rosin 0.5～10% or ester gum 2～10%, oxidation inhibitor (as 2,6 one di-tert-butyls-4-cresylol etc.) 0.1～0.5%, hard ester acid 0.5～5%, silicone oil 0.01～0.1%, solvent (as toluene, dimethylbenzene, methylene dichloride, trieline and gasoline etc.) 70～90%.
Solvent toluene is heated to 40～110 ℃, and by dissolving in it, the solute of waiting all adds an amount of gasoline dilution after the dissolving again, to reduce the toxicity of toluene, is beneficial to the volatilization of coating back solvent again EVA resin and ester gum etc.The present invention also makes the storagetank of common coating machine into chuck heating or the groove airtight far infrared heater heating of placement down, is aqueous to guarantee the tackiness agent in the storagetank, and the temperature of storagetank generally is controlled at 40～100 ℃ in order to even coating.Also the container of seasoning tackiness agent is also made the equipment that can heat simultaneously, in the bucket exit, the tackiness agent that outflow tap mouth is flow in the storagetank is always liquid, rather than the jelly shape with screen cap.Chart drive speed is 2～10m/min during coating, by regulate the film thickness that two between centers clearance control tackiness agent form on paper, makes every square of rice paper coating 2～16g(dry product meter) tackiness agent.Passage (temperature be controlled at 50～120 ℃) oven dry of the paper of coated with adhesive through heating rod and hot-blast are arranged, solvent in the tackiness agent brings to ventilation duct cooling back by hot blast and recycles, the EVA resin is distributed in paper surface equably and forms one deck and the paper very thin film that is bonded together, and promptly gets medical gluing ventilating paper.
According to the different requirements of medical device package, can select for use the roll paper of different size or flat stacker to be coated with and make medical gluing ventilating paper, cut into the coil paper or the flat stacker of different in width, put into (20～80 ℃ of vacuum drying ovens, 5～40min takes out after removing residual trace solvent in 600～760mmHg), packing.
Medical gluing ventilating paper shows nontoxic through institute for drug control, Shanghai toxicity test, can be used for the medicine equipment outer packaging.It and high molecular polymer medical device package plastics films such as polyethylene, polypropylene, polyester, polymeric amide and polyvinyl chloride stitch weldering and make plastics bag, box or the case that medical gluing ventilating paper seals on high-frequency induction welder.
