Abstract
The invention relates to a method for producing adhesive flexible bond. Wherein, it uses flexible fabric, uses dual-layer adhesive machine. And the method comprises preparing adhesive, preparing flexible fabric, plating adhesive on the fabric, drying and producing final product. The invention coats adhesive on two surfaces of flexible fabric synchronously, with high efficiency. And it has uniform adhesive and better penetration.
Description
Technical field
The present invention relates to a kind of manufacture method of medical bandage, relate in particular to a kind of manufacture method of self-adhesive elastic bandage.
Background technology
At present, medical bandage product coating technique mainly contains several methods such as spraying, blade coating, roller coating, dip-coating.Spraying process is lower because of used adhesive solid content, produces atomizing on spraying process, and the glue waste is more, and utilization rate is low, easily environment is polluted simultaneously; The shortcoming of scraping coating method is that the glue-line that is coated with is even inadequately, the properties of product instability; Dip coating mainly is to push after allowing base material immerse adhesive again, and the product breathability of manufacturing is poor, bubbles because of the airtight skin whitening that makes easily during use; Roll coating process generally can only single spreading, and production efficiency is lower.
Said method also exists the adhesive solid content lower, and drying time institute's calorific requirement is more, the shortcoming that energy consumption is high.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of good evenness of product glue-line to be provided, and the product breathability is good, the manufacture method of the self-adhesive elastic bandage of efficient, energy-saving and environmental protection.
The objective of the invention is to be achieved through the following technical solutions: a kind of manufacture method of self-adhesive elastic bandage may further comprise the steps:
(1) preparation adhesive
Prepare adhesive by following component and weight portion content: 100 parts of Heveatexes, 0.5～5 part of thickening agent;
(2) prepare the elastic fabric base material
Choosing a kind of in non-woven fabrics, elasticity cotton, elastic polyurethane fiber cloth or the elasticity gauze places on the unwinding device as the elastic fabric base material;
(3) fabric gluing
The adhesive that step (1) is prepared is coated on the two sides of the elastic fabric base material that step (2) prepared equably by a dual-layer adhesive machine;
(4) oven dry
Step (3) gained material is placed oven for drying;
(5) make finished product
With the material after the oven dry through bundling, cut, repair, be packaged to be the self-adhesive elastic bandage finished product.
Described Heveatex is the nature rubber latex that contains the 35-68% natural rubber.
Described thickening agent is one or both the mixture in polyacrylate dispersion or the polyaminoester emulsion.
Dual-layer adhesive machine described in the step (3) comprises four round rollers that be arranged in parallel, forms two gluing combinations respectively, wherein is positioned at intermediary two rollers for can gummed upper glue roller being carried out on the two sides of elastic fabric simultaneously.
Fabric gluing described in the step (3) control coating speed be 5-50 rice/minute.
The temperature of the oven for drying described in the step (4) is controlled at 80-140 ℃.
Compared with prior art, the present invention makes the production efficiency height of self-adhesive elastic bandage at two surface while of elastic substrate gluing; The double spread of applicable multiple elastic substrate, and gluing is even, and the product breathability is good.The self-adhesive elastic bandage that adopts method of the present invention to make have can the oneself twine sticking, viscosity is moderate; can fix arbitrarily; advantage such as can not come off can be conveniently used in motion, hospital, beasts protection, field emergency, industrial labour protection, also is the desirable articles for use of family health care simultaneously.
