Abstract
The utility model discloses low-cost medical breathable tape. The low-cost medical breathable tape comprises a medical hot-melt pressure-sensitive adhesive coating, a base material layer and a waterproof and moisture permeable coating, wherein the medical hot-melt pressure-sensitive adhesive coating, the base material layer and the waterproof and moisture permeable coating are sequentially arranged from top to bottom, netted air holes are formed in the base material layer, and the medical hot-melt pressure-sensitive adhesive coating and the waterproof and moisture permeable coating are attached to the base material layer. The low-cost medical breathable tape has the advantages that base material pretreatment steps are reduced, no intermedium is used for colloid transferring, and the production process is safe and free of pollution; the production cycle is short, and cost is effectively reduced; the finished low-cost medical breathable tape is used for binding and fixing, has good breathability and flatness and can be used more conveniently.
Description
Technical field
This utility model relates to a kind of low-cost medical breathable adhesive tape, belongs to medical material tech field.
Background technology
Traditional Medical adhesive plaster adhesive tape is to take cotton as base material, with zinc oxide, natural rubber and Colophonium etc., makes for binding agent, easily produces pruritus and the easily redness harmful effect such as get blister after adhering skin.And along with the appearance of this new medical macromolecular material of pressure sensitive adhesive tape (abbreviation pressure sensitive adhesive), its viscosity is good, consumption is few, without rubber intrinsic easily aging, come off and the problem such as zest is large, its advance can replace traditional traditional products such as rubber plaster.Domestic normally used medical permeable adhesive tape mostly is with solvent-borne type rubbing method and the manufacture of emulsion-type rubbing method and forms.Solvent-borne type rubbing method is that binding agent is first dissolved in to (as gasoline, dimethylbenzene etc.) in solvent, after dissolving, be applied to again on adhesive (kraft paper, polyethylene film, silicone), drying process use again transfer coated method by adhesive transfer to base material, form breathability paster.Owing to selecting the frivolous property of base material, conventionally substrate backside need to first carry out starching processing, blocks pore and push after smooth to be coated with organic silicon-fluorine class material to reduce the adhesion of glue-line to substrate surface.And emulsion-type coating rule is glue is made to emulsion or be dissolved in a certain proportion of water, be then coated on adhesive, through shifting, be coated on breathability base material, drying is processed and is formed permeable adhesive tape.
The solvent that solvent-borne type rubbing method is used is inflammable and explosive, volatile, poisonous to human body, and production process has certain pollution to environment.And product resistance to water, peeling force and initial bonding strength that emulsion-type rubbing method is made are low, low-temperature stability is poor, little to pasta adhesion, and energy consumption is high, solidifies slow.Both all need be after organosilicon solidifies can coating adhesive, hardening time is long, the yielding foaming of base material or generation fold, cause crawling even.In the production process of the waterproof and breathable adhesive tape of producing at transfer method, solvent and emulsion all need to dry, and base material also will carry out twice drying and processing, and the production time is long, and energy resource consumption is large; And above-mentioned two kinds of adhesive tapes that method is made, during use, can only use the adhesive glue face portion that is stained with pressure sensitive adhesive, remainder (antiseized base material, slurry, antitack agent etc.) abandon and need not, increased the waste of the manpower and materials of product, product cost is also corresponding higher, and competitiveness reduces.
Utility model content
The purpose of this utility model is to provide a kind of low-cost medical breathable adhesive tape, to solve the too high problem of the production cost of medical air-permeable adhesive tape in prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of low-cost medical breathable adhesive tape, comprise: the medical hot melt pressure-sensitive adhesive coating from top to bottom setting gradually, substrate layer and Waterproof Breathable coating, on described substrate layer, be formed with Reticular breathable hole, described medical hot melt pressure-sensitive adhesive coating and Waterproof Breathable coating are fitted on substrate layer.
As a kind of preferred version, described substrate layer is medical gummed tape cotton paper.
The beneficial effects of the utility model are mainly reflected in: reduced the pre-treatment step to base material, do not used intermediate medium to carry out colloid transfer, production process safety non-pollution; With short production cycle, cost effectively reduces; Finished product is used for wrapping up fixing, and breathability and flatness are good, uses also convenient.In addition, owing to selecting nonpoisonous and tasteless medical hot melt pressure sensitive adhesive, manufactured goods do not have the dissolvent residual taste of solvent-borne type product after high-temperature sterilization, viscosity stabilized lasting.
Accompanying drawing explanation
Fig. 1 is the structural representation of low-cost medical breathable adhesive tape of the present utility model;
Fig. 2 is the production technological process of low-cost medical breathable adhesive tape of the present utility model.
The specific embodiment
Referring to accompanying drawing 1, medical air-permeable adhesive tape of the present utility model be by medical hot melt pressure-sensitive adhesive coating 1, substrate layer 2, Waterproof Breathable coating 3 form, and are formed with Reticular breathable hole on described substrate layer, and described medical hot melt pressure-sensitive adhesive coating and Waterproof Breathable coating are fitted on substrate layer.Substrate layer 2 network structure own can be stablized respectively firmly medical hot melt pressure-sensitive adhesive coating 1 and Waterproof Breathable coating 3, and play the effect of isolation.Effectively and base material combination, finished product is difficult for producing cull, excessive glue to the part that this new technology makes pressure-sensitive adhesive coating; Viscosity stabilized, be not subject to the impact of temperature and humidity, greatly improved medical personnel's work efficiency, and conveniently stored and use.
Embodiment 1, resin, thickening agent, waterproofing agent and water are mixed with to W/O emulsion according to the weight ratio of (10:6:3:100), it is waterproofing slurry, this waterproofing slurry and interleaving agent are coated on to the back side that grammes per square metre is the import medical gummed tape cotton paper of 26 ± 3g/ ㎡, make import medical gummed tape cotton paper weightening finish 0.02-0.5g/ ㎡, permeability reaches 1～99% of import medical gummed tape cotton paper thickness, then send in coating drying integral machine, the direct speed with 30-40m/min, by modes such as hot blast, baking ovens, dry, the parameter that coating drying integral machine is set is:
Coating head flow: 900-200mL/min; Interlock ratio: 0.9; Charging rate: 40 ± 15m/s; Dry air quantity: 35 ± 5Hz; Oven temperature (T1-T6): 150 ± 20 ℃; Traction wheel tension force: 1.5～3.5kg; Winding tension 35 ± 5kg.
The import medical adhesive tape of coated waterproof coating is sent in hot melt coating machine, and at the RT1100 hot melt coating machine coating CM919 hot-fusible pressure-sensitive adhesive for front of import medical gummed tape cotton paper, the parameter of setting hot melt coating machine is as follows:
Heat conduction transferring roller temperature: 80 ± 10 ℃; Chill-roll temperature: 5-10 ℃; Coating head temperature: 170 ± 10 ℃; Glue case temperature: 140 ± 10 ℃; Spread is set: 22 ± 2g (interlock); Coating speed: 30 ± 5m/s;
