Abstract

The invention relates to composite hydrocolloid, a preparation method thereof and a hydrocolloid dressing. The composite hydrocolloid is prepared from the following raw materials: 15 to 90 parts of an effective component, 10 to 30 parts of sodium carboxymethylcellulose and 40 to 100 parts of an adhesive, wherein the effective component comprises tourmaline powder and / or tea tree essential oil wrapped by microcapsules. The far infrared tea tree essential oil application is suitable for later recovery of superficial wounds and burn and scald wounds and inflammation elimination and nursing of acnes, and has a more outstanding effect than common inflammation elimination medicines or dressings.

Description

technical field [0001] The invention relates to a composite hydrocolloid, a hydrocolloid dressing and a preparation method thereof. Background technique [0002] Hydrocolloid functional dressing is a new type of dressing with the advantages of adsorption, waterproof, anti-adhesion, and moisturizing. At present, hydrocolloid functional dressings are widely used in a wide range of applications. The materials used and the auxiliary materials added determine different functional characteristics and types of wounds to be treated. The quality of hydrocolloid dressings on the market varies greatly. For different wound characteristics, hydrocolloid functional dressings with good safety and specific functions are required. [0003] A number of hydrocolloid patents have been retrieved from domestic and foreign patents. This type of hydrocolloid application patents mainly uses styrene, gelatin, chitosan, calcium alginate fiber, silver ions and other auxiliary materials. The functional...
