Embodiment 1

[0021] Example 1, resin, thickener, waterproofing agent and water are formulated into W / O emulsion according to the weight ratio of (10:6:3:100), that is, waterproof slurry, and the waterproof slurry and release agent are coated On the back of the imported medical tape tissue paper with a grammage of 26±3g / ㎡, the weight of the imported medical tape tissue paper is increased by 0.02-0.5g / ㎡, and the penetration reaches 1-99% of the thickness of the imported medical tape tissue paper, and then sent Put it into the coating and drying integrated machine, and dry it directly at a speed of 30-40m / min with hot air, oven, etc., and set the parameters of the coating and drying integrated machine as follows:

[0022] Coating head flow rate: 900-200mL / min; linkage ratio: 0.9; feeding speed: 40±15m / s; drying air volume: 35±5Hz; oven temperature (T1-T6): 150±20℃; pulley tension: 1.5~3.5kg; winding tension 35±5kg.

[0023] Send the imported medical tape coated with a waterproof coating into...

Abstract

The invention discloses low-cost medical breathable tape and a manufacturing method thereof. 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 arranged in sequence from top to bottom, netty 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 manufacturing method of the low-cost medical breathable tape comprises the steps of (a) preparing waterproof slurry for use, (b) enabling the back side of the breathable base material layer to be coated with separant and the waterproof slurry prepared in the step (a) and drying the separant and the waterproof slurry, and (c) adhering medical hot-melt pressure-sensitive adhesive to the front side of the breathable base material layer and carrying out rewinding and cutting after the medical hot-melt pressure-sensitive adhesive is dried. The low-cost medical breathable tape and the manufacturing method thereof have the advantages that preprocessing steps of base materials are simplified, no intermedium is used for colloid transferring, and the production is safe and free of pollution; the production cycle is short and cost is effectively reduced; finished low-cost medical athletic tape is used for binding and fixing, breathability and flatness are good, and using is more convenient.

Description

technical field [0001] The invention relates to a low-cost medical air-permeable adhesive tape and a preparation method thereof, belonging to the technical field of medical materials. Background technique [0002] The traditional medical adhesive plaster tape is made of cotton cloth as the base material, and zinc oxide, natural rubber and rosin are used as adhesives. After the skin is bonded, it is prone to itching, redness, swelling and blisters and other adverse effects. With the emergence of a new type of medical polymer material, pressure-sensitive medical adhesive tape (referred to as pressure-sensitive adhesive), it has good viscosity, less dosage, and no problems such as easy aging, falling off and irritating inherent in rubber. The advanced nature can replace traditional products such as traditional rubber plasters. Most of the medical air-permeable adhesive tapes commonly used in China are manufactured by solvent-based coating method and emulsion-type coating metho...
