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

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...
