Problems solved by technology

However, because natural latex contains a small amount of soluble proteins, and these soluble proteins can cause allergic reactions on human skin, common self-adhesive elastic bandages may cause skin allergies when used.
Self-adhesive elastic bandages cannot be directly in contact with human skin or wounds during use, which limits the use of self-adhesive elastic bandages and reduces their economic benefits
Some people use synthetic natural latex instead of natural latex to prepare self-adhesive elastic bandages. Although some effects have been achieved, the self-adhesive self-adhesive elastic bandages of synthetic rubber are not good, and they are easy to fall off when used. The preparation of synthetic natural latex is cumbersome and unstable, and the cost is relatively high high

Embodiment 1

[0016] 1. Low-protein or deproteinized natural latex refers to the use of natural latex as raw material to remove the soluble protein in natural latex by mechanical sedimentation, chemical sedimentation, vulcanization irradiation or other methods, so that the soluble protein content in natural latex is reduced to 110 ×10 -6 The following preparations are ready to use.

[0017] 2. Glue preparation: Prepare the ingredients according to the following composition by weight:

[0018] Low protein or deproteinized natural latex 100

[0019] Water 100~150

[0020] Sodium lauryl sulfate 10~50

[0021] Antiaging agent 264 1~10

[0022] Methyl p-hydroxymethylbenzoate 1~10

[0023] White oil 1~10

[0024] First weigh low-protein or deproteinized natural latex and water into the reactor, add anti-aging agent 264, stir for a certain period of time, add sodium lauryl sulfate and white oil to the glue in the reactor by dropping, wait for the reaction After a certain period of time, add...

Embodiment 2

[0027] Preparation technology is with embodiment 1, difference is:

[0028] Sodium dodecylbenzenesulfonate is used as emulsifier, Wingstay-L and Lowinoxcpl are used as anti-aging agent, ethyl p-hydroxybenzoate is used as preservative, glycerin is used as smoothing agent, and bandage base material is made of elastic cotton and chemical fiber blended fabric.

Embodiment 3

[0030] Preparation technology is with embodiment 1, difference is:

[0031] The emulsifier uses sorbitol stearate and fatty alcohol polyoxyethylene ether (AEO-3), the anti-aging agent uses anti-aging agent 2246, the preservative uses ethyl p-hydroxybenzoate and potassium sorbate, and the smoothing agent uses white oil and olive Oily, the base material of the bandage is made of elastic non-woven fabric.

Abstract

The invention discloses a non-sensitized self-adhesive elastic bandage and a preparation method thereof, which belong to the technical field of medical material. The non-sensitized self-adhesive elastic bandage comprises a bandage substrate and non-sensitized glue, wherein the non-sensitized glue comprises the following compositions in portion by mass: 100 portions of low-protein or deproteinization natural emulsion, 100 to 150 portions of water, 10 to 50 portions of an emulsifier, 1 to 10 portions of an anti-aging agent, 1 to 10 portions of an antiseptic and 1 to 10 portions of a smoothing agent. The method combines the formula and the preparation technology to prepare the non-sensitized self-adhesive elastic bandage after specially treating the low-protein or deproteinization natural emulsion. The bandage has the advantages that the bandage completely accords with the standards after undergoing biological performance detection, can not cause anaphylaxis of the human skin, is safe to use and has no toxic and side effects; and simultaneously the bandage has moderate self viscosity, only generates self-adhesion, does not adhere to the skin, the hair and so on, and is convenient to use.

Description

technical field [0001] The invention relates to a bandage, in particular to a non-allergenic self-adhesive elastic bandage and a preparation method thereof, which can be widely used in the fields of medical dressings, sporting goods and the like. Background technique [0002] As a kind of medical dressing, bandages are widely used in medical fields such as surgery and wound dressing. At the same time, they are also widely used in daily care and sports protection, mainly for supporting, protecting, orthopedic and other special functions. Self-adhesive elastic bandage is easy to use and does not need other objects to fix it. It only sticks to itself and does not stick to skin or hair. It has a wider range of applications and is the first choice for medical care, fashion sports, and pet grooming. The preparation of self-adhesive elastic bandages generally adopts natural latex as an adhesive, which is sprayed on substrates such as non-woven fabrics or cotton cloths, and is dried...
