Abstract
This invention discloses an adhesive used on medical packaging paper bags. The adhesive comprises: main component polymer 10-35 wt.%, viscous resin 2-10 wt.%, lubricant 0-5 wt.%, solvent oil 60-90 wt.%, and coloring agent 0.001-0.002 wt.%. The main component polymer is an ethylene-vinyl acetate copolymer (EVA), or a mixture of two EVAs. The method for manufacturing medical packaging paper bags comprises: (1) coating medical paper with the adhesive; (2) placing the coated medical paper and PE-laminated paper in a bag maker, and adhering by hot-pressing at a T peeling strength of 5+-1 N/cm; (3) Peeling to transfer the adhesive layer to obtain the medical packaging paper bags. No leakage occurs when the bags are filled with a solution of 0.15% tween, 0.15% amaranth, 5% ethanol and 100 mL H2O at room temperature for 24 h. The bags have such advantages as convenient usage, moderate strength and good sealing.
Description
Technical field: the invention belongs to adhesive area, specifically about a kind of tackiness agent that is used for the medical package paper bag.
Background technology; Along with progressively integrating with of China and International Packaging, more and more higher to the packing instructions of curable product, consider needs simultaneously to environment protection, praise highly in the world paper compound, mould packaged form with paper generation.And medical paper bag is exactly a kind of product of satisfied modern medical package requirement, and it generally adopts paper, leaching membrane paper or lacquer painting paper is compound makes, and has the advantages that sealing is reliable, heat-sealing is easily torn.This product can be used for the packing of medical gloves, gauze, mouth mask, disinfecting towel and medical little apparatus, has obtained abroad more generally using, and domestic demand is also increasing.The manufacturing of medical disinfecting coated paper envelope is that the High Temperature High Pressure by bag machine makes raw-material rubberised layer and leaching membrane layer bonding, thereby makes it reach good stopping property, and requires the interface of peeling off definitely clean for the medical package paper bag in use.These characteristics at medical paper bag just need be selected special hot-melting type seal adhesive for use, thereby make product satisfy good airproof performance, easily between the bonding ply of paper, peel off, and peel off the back glue-line and transfer to leaching membrane paper one side, not inter-adhesive performance requriements after peeling off by leaching membrane paper one side not.Present medical bag paper bag is general to adopt the gusset at medico paper to be coated with a circle tackiness agent around the edge frame, cover leaching membrane paper then, heat pressure adhesive, cut, thereby formation paper bag, reserve on one side during hot pressing so that put into packing material, seal opening one end to be sealed on the heat seal bag sealer and get final product, during use as long as peel off and can open from the two layers of paper bonding place at the paper bag opening end.
At present, there is following shortcoming in commercially available medical paper bag:
1. two layers of paper can not be separated from the bonding place fully, easily cause paper bag to tear, or the paper fiber is torn;
2. bonding coat stopping property deficiency produces seepage, can not satisfy hygienic requirements.
Summary of the invention: the purpose of this invention is to provide a kind of solvent-borne type hot melt adhesive that is used for the good heat sealability of having of medical package paper bag and peels off effect, this tackiness agent has following characteristic: tackiness agent is easy to coating, heat-sealing back bonding strength is moderate, and pack into tween-ethanol aqueous solution 24 hours of the paper bag after the heat-sealing is impermeable.When paper bag was torn, glue-line was transferred to the leaching membrane paper face and the paper fiber that is unlikely to tear by paper.
Technical scheme of the present invention is as follows: the present invention glues the body polymkeric substance with the ethylene-vinyl acetate copolymer (EVA) of different molecular weight and different vinyl acetate contents or two kinds of (EVA) blend as the master, be aided with tackifying resin, tinting material, slipping agent etc. again, use the good and avirulent organic solvent dissolution of consistency to form.
The composition of tackiness agent of the present invention (weight %) is: main sticking body polymkeric substance is that ethylene-vinyl acetate copolymer (EVA) adopts a kind of or two kinds of blend 10～35, tackifying resin 2～10, slipping agent 0～5, solvent 60～90, tinting material 0.001～0.002.
The sticking body polymkeric substance of described master is ethylene-vinyl acetate copolymer (EVA), selects for use ethylene-vinyl acetate copolymer (EVA) blend of one or both different vinyl acetate contents, different melt viscosities to use, and the VA content of EVA is 28-45, and the MI value is 20-400.Its weight % is 10-35, optimum range 15-25.
The two blend can adjust that bonding strength is moderate, and cohesive strength is moderate, glued membrane only takes place shift, and adhesion destroys the hot melt adhesive of paper fiber.
Described tackifying resin can adopt fatty hydrocarbon petroleum resin, modified rosin resin, and as ester gum, rosin pentaerythritol ester, the alpha-methyl styrene resin (α-MS-80) etc., softening temperature (ring and ball method) is generally about 100 ℃.(α-MS-80) is best, and its weight % is 2-10, optimum range 3-8 with the alpha-methyl styrene resin.Demonstrate good consistency, the cementability of appropriateness, flowability etc.
Described organic solvent for ethylene-vinyl acetate copolymer (EVA) resin is had excellent compatibility and avirulent in low boiling range solvent, as 120
#Solvent oil or vinyl acetic monomer.Its weight % is 60-90, optimum range 70-80.
Described slipping agent is for being polyethylene wax (PE-Wax) or paraffin, and its weight % is 0-5, and optimum range is 1-3
Described tinting material is blue 106 dyestuffs of oil soluble.
The preparation technology of this tackiness agent is as follows:
Earlier solvent is dropped into reactor, open and stir back adding ethylene-vinyl acetate copolymer resin (EVA), tackifying resin, materials such as slipping agent and tinting material are warming up to 40 ℃, treat to dissolve fully even postcooling, discharging.
