Problems solved by technology

Removing the medical dressing from an adult often feels a "tearing pain", and if the medical dressing is removed from the baby's skin, it is likely to damage the skin and cause obvious scars
In addition, most of the currently used medical applicators have poor compatibility with the skin, poor air permeability and water absorption. When they are attached to the skin for a long time, water accumulation will occur, and the skin will be macerated or even whitened, causing damage to the skin. , and even cause bacterial infection of the wound, affecting the therapeutic effect

Embodiment approach

[0043] The term "tackifier" in the present invention means that it is added to the adhesive, has a wetting effect on the adherend, and can produce high adhesion under certain conditions (temperature, pressure, time) through surface diffusion or internal diffusion. sexual substance. Common tackifiers include terpene resins, C 5 Petroleum resin, C 9 Petroleum resin, C 5 / C 9 Copolymer resin, rosin, hydrogenated rosin, polymerized rosin, rosin glyceride, 210 resin, 422 resin, 240 resin, ancient road resin, QMS resin, polyethylene, etc. Dermatitis is often caused by acidic tackifying resins such as rosin and its derivatives, certain phenolic modified products, etc. Therefore, as a preferred embodiment of the present invention, the tackifier is one or more of polyethylene, polypropylene, polystyrene and polyisobutylene.

[0044] The term "plant polysaccharide" in the present invention refers to a compound composed of many identical or different monosaccharides with α- or β-gly...

Embodiment approach 1

[0056] Embodiment 1, a kind of medical application adhesive, said medical application adhesive is prepared from raw materials comprising the following percentages by weight:

[0057] SBS 20~40%

[0058] Tackifier 30~50%

[0059] Plant polysaccharide 5~10%

[0060] Modified nano zinc oxide 2~5%

[0061] White mineral oil 10~30%

[0062] Antioxidant 0.3~0.8%;

[0063] Wherein, the modified nano-zinc oxide is prepared by modifying the nano-zinc oxide with a silane coupling agent.

Embodiment approach 2

[0064] Embodiment 2 is the same as Embodiment 1, except that the SBS is a mixture of different molecular weights, wherein those with a number average molecular weight of 5000 to 20000 account for 10 to 25% of the total weight of the SBS, and the number average molecular weight is 30000 Those with a molecular weight of ~85,000 account for 35-50% of the total weight of SBS, and those with a number average molecular weight of 90,000-110,000 account for 25-40% of the total weight of SBS.

Abstract

The invention discloses a medical application adhesive and a preparation method thereof. The medical application adhesive comprises SBS, plant polysaccharide, modified nano-zinc oxide, white mineral oil and an antioxidant. The medical dressing prepared from the medical application adhesive through coating has better bio-adhesion, good air permeability, antibacterial property, no sensitization, no residue, strong permanent adhesion and stripping performance.

Description

technical field [0001] The invention relates to a medical adhesive used in the field of medical and sanitary materials, and more specifically, the invention relates to a medical application adhesive and a preparation method thereof. Background technique [0002] Clinically, medical applicator is a kind of applicator used by doctors to patients for wound repair. With the improvement of medical level, the comfort of medical application is more and more valued by medical staff and patients. When removing the medical applicator from an adult, you will often feel a "tearing pain". If you remove this medical applicator from the baby's skin, it is likely to damage the skin and cause obvious scars. In addition, most of the currently used medical applicators have poor compatibility with the skin, poor air permeability and water absorption. When they are attached to the skin for a long time, water accumulation will occur, and the skin will be macerated or even whitened, causing damag...
