Synthesized natural latex self-adhered elastic bandage and manufacturing method thereof

Abstract

The invention discloses a synthesized natural latex self-adhered elastic bandage and a manufacturing method thereof. The elastic bandage is composed of a synthesized natural latex adhesive and an elastic fabric component. The synthesized natural latex adhesive comprises components of: 100 parts of synthesized natural latex, 1-30 parts of a tackifying reinforcing auxiliary agent, and 0.1-3 parts of an antioxidant. The preparation method comprises steps that: the prepared synthesized natural latex adhesive is uniformly coated on two surfaces of the elastic fabric through spraying, dip-coating, roll-coating, and scrape-coating technologies; the fabric is dried and is processed by using a reeling apparatus, such that the synthesized natural latex self-adhered elastic bandage product provided by the invention is obtained. The self-adhered elastic bandage is advantaged in good safety, environment-friendliness, allergy-resistance, mildew resistance, good air permeability, convenient application, and the like.

Description

technical field [0001] The invention relates to the technical field of bandages, in particular to a synthetic natural latex self-adhesive elastic bandage and a manufacturing method thereof. Background technique [0002] The production technology of existing self-adhesive elastic bandage mainly contains following two big classes: [0003] One is a self-adhesive elastic bandage made by coating water emulsion adhesive on the surface of various elastic substrates. [0004] There are two main types of water emulsion adhesives used in this type of self-adhesive elastic bandage: the first is to use pure natural rubber latex to prepare adhesive as a self-adhesive elastic bandage produced by self-adhesive adhesive. A Chinese invention patent of ZL00117267.0 describes a natural latex medical self-adhesive bandage. The adhesive contains 100 parts of natural latex, 10-50 parts of white oil, 1-10 parts of butyl acrylate, and 0.1-10 parts of potassium sorbate. 1 part and MOA-30.5-5 part...

AI Technical Summary

Problems solved by technology

[0004] There are two main types of water emulsion adhesives used in this type of self-adhesive elastic bandage: the first one is to use pure natural rubber latex to prepare adhesive as a self-adhesive elastic bandage produced by self-adhesive adhesive. A Chinese invention patent of ZL00117267.0 describes a natural latex medical self-adhesive bandage. The adhesive contains 100 parts of natural latex, 10-50 parts of white oil, 1-10 parts of butyl acrylate, and 0.1-10 parts of potassium sorbate. 1 part and MOA-30.5-5 parts, because natural latex contains protein substances, long-term storage will not only cause mildew, but also cause skin allergic reactions; secondly, natural latex uses ammonia as a stable protective agent, the glue preparation process The ammonia gas escaped from the air will have adverse effects on the operating environment

The second kind utilizes hydrosol to make self-adhesive elastic bandage, as the Chinese invention patent application that the patent application number is 201010171978.6 records a kind of hydrosol self-adhesive elastic bandage, and this hydrosol contains emulsion adhesive 62~90%, tackifier 0.1~ 10%, softener 0.5-20%, anti-aging agent 0.001-2%, environmental protection additive 0.1-5% and colorant 0.1-1%. The emulsion used not only uses a large amount of organic solvents, but also many surfaces necessary for emulsification. Active auxiliary agent makes the preparation process complicated and not easy to operate, and because the surfactant is very active, it is easy to accumulate on the surface of the product after a certain period of time, forming an isolation layer on the surface of the adhesive layer, resulting in a decline in product performance; in addition, due to the use of materials Limited by its own characteristics, it cannot achieve the inherent viscoelastic properties of natural rubber (the main component of polyisoprene polymer), and the self-adhesive effect is relatively poor

Both of the above two patented technologies use a large amount of gasoline in the process of processing, not only the cost is high, the solvent volatilization causes environmental pollution and energy waste, and there are potential safety hazards; moreover, the solvent volatilization in the product is not complete, and the oily smell is heavy, which has fatal defects
