Embodiment 1

[0026] Put 170 grams of rubber elastic body, 90 grams of plasticizer and zinc oxide into the sigma mixer according to the composition ratio in Table 2, and mix for 45 minutes at 150°C. Then at 140 DEG C, 250 grams of tackifier were added and continued to mix for 30 minutes. At a temperature of 120 DEG C, 490 grams of hydrophilic polymer sodium carboxymethyl cellulose CMC was dropped into the mixer, and continued to mix for 20 minutes.

[0027] The elastomer is Kraton's product polyethylene isoprene ethylene D1611.

[0028] The plasticizer is mineral oil or DOP.

[0029] The tackifier is C5 hydrocarbon petroleum resin of Clay Power.

[0030] The hydrophilic polymer is sodium carboxymethyl cellulose CMC of Ashland Company of the United States.

[0031] Zinc oxide was purchased from Aladdin Corporation.

Embodiment 2

[0032] Example 2 sample preparation

[0033] The hydrocolloid prepared by embodiment 1 is put into an extruder and extruded into a sheet with a thickness of 0.45mm, and simultaneously rolled and clad on the hydrocolloid sheet with polyurethane film and release paper to obtain a hydrocolloid dressing material.

Embodiment 3

[0034] Embodiment 3 water absorption test

[0035] Water absorption test: Cut the sample into a circular sample with a diameter of 1 inch with a cutter; stick the sample and PP synthetic paper with double-sided tape; remove the backing, weigh it, and place it in 60ml of test solution , Take it out at 2, 4, 6, 18, 24, 48, and 72 hours, and weigh it when it stops dripping, and measure it by water absorption.

[0036]

[0037] where W 2 Weigh the weight for the nth hour, W 1 It is the weight of the application sample and PP synthetic paper. The water absorption results are shown in Table 2.

Abstract

The invention relates to the field of medical colloidal fixing adhesives and wound dressings, in particular to a hydrocolloidal adhesive especially applicable to the preparation of various wound dressings or stoma bases, seal materials and fixing materials, and an applicator. The hydrocolloidal adhesive and the applicator are characterized in that the hydrocolloidal adhesive comprises zinc oxide, a plasticizer, a rubber elastic material and a hydrophilic polymer. The hydrocolloidal adhesive containing zinc oxide has high exudate absorbing efficiency and excellent self-adhesion, stoma and wound peculiar odors can be decreased or eliminated, a patient's pain and inconveniences are relieved, mental block is overcome, the patient's self-confidence is enhanced, and early recovery to health is benefited.

Description

Technical field: [0001] The invention relates to the field of medical colloid fixing adhesives and wound dressings, in particular to a hydrocolloid adhesive that is particularly suitable for preparing various wound dressings or stoma chassis, sealing materials and fixing materials that can suppress or absorb peculiar smell And apply. Background technique: [0002] Hydrocolloids are mainly composed of elastomer polymer materials, plasticizers, viscosifying materials and hydrophilic polymer materials. It has elastic self-adhesive and water-absorbent functions at the same time. The hydrophilic polymer material swells after absorbing water, forming a layer of wet gel, which promotes wound debridement and wound healing. When the colloidal material is removed, there is no adhesion to the wound, no secondary trauma, and almost no pain. therefore. Hydrocolloids are widely used in wound care and ostomy care. [0003] Ordinary hydrocolloid materials do not have the function of in...
