Embodiment 1

[0025] The present embodiment is a medical silicone gel tape, combined with figure 1 , including the non-woven layer 1, the silicone gel layer 2 and the release substrate 3, the non-woven layer 1, the silicone gel layer 2 and the release substrate 3 are arranged in order from top to bottom, and the silicone gel layer 2 It is formed by compounding semi-solid silicone gel on the non-woven fabric layer 1, and the release substrate 3 is attached to the silicone gel layer 2; when in use, the release substrate 3 is peeled off, and the silicone gel layer 2 is directly attached on the skin.

[0026] Among them, in this embodiment, the release substrate 3 is a fluorine release film with a thickness of 0.1 mm, and the amount of silicone gel glue is 100 g / m 2 , the non-woven fabric is spunlace non-woven fabric, the thickness is 35g / m 2 .

[0027] Step A: Apply the silicone gel to the release surface of the fluorine release film on the gluing machine according to the above amount of gl...

Embodiment 2

[0032] The setting and working principle of this example are the same as those of Example 1. The difference is that the release substrate 3 is a fluorine release film, with a thickness of 0.1 mm and a silicone gel gluing amount of 75 g / m. 2 , the non-woven fabric is spunlace non-woven fabric, the thickness is 40g / m 2 .

[0033] Step A: Apply the silicone gel to the release surface of the fluorine release film on the gluing machine according to the above amount of glue;

[0034] Step B: the first oven heating, the oven temperature is set to 65°C, and the heating time is 2min;

[0035] Step C: compound the non-woven fabric to the surface of the silicone gel;

[0036] Step D: the second oven heating, the oven temperature is set to 110 ° C, the heating time is 4 minutes, and finally the roll is wound and cut into corresponding specifications.

Embodiment 3

[0038] The setting and working principle of this example are the same as those of Example 1, the difference is: the release substrate 3 is a fluorine release film, the thickness is 0.1mm, and the amount of silicone gel glue is 150g / m 2 , the non-woven fabric is spunlace non-woven fabric, the thickness is 30g / m 2 .

[0039] Step A: Apply the silicone gel to the release surface of the fluorine release film on the gluing machine according to the above amount of glue;

[0040] Step B: the first oven heating, the oven temperature is set to 100°C, and the heating time is 1.5min;

[0041] Step C: compound the non-woven fabric to the surface of the silicone gel;

[0042] Step D: the second oven heating, the oven temperature is set to 130 ° C, the heating time is 4 minutes, and finally the roll is wound and cut into corresponding specifications.

Abstract

The invention discloses a medical silicone gel tape and preparation method thereof, which relates to the technology field of materials or devices of a bandage, a dressing, an absorbent pad or and a surgical article. The medical silicone gel tape comprises a nonwoven fabric layer, a silicone gel layer and a release type substrate. The nonwoven fabric layer, the silicone gel layer and the release substrate are arranged in order from top to bottom. The silicone gel layer is formed on the nonwoven fabric layer by a silicone gel semi-solid state. The medical silicone gel tape and preparation method thereof is applied to medical clinical dressing, and has the advantages of good air permeability, good fit and the like.

Description

technical field [0001] The invention relates to a medical silicone gel adhesive tape and a preparation method thereof, belonging to the technical field of materials or devices for bandages, dressings, absorbing pads or surgical supplies. Background technique [0002] Medical tapes are generally attached to the skin and are mainly used to fix wounds or as dressings; [0003] At present, the common medical tapes on the market are mainly divided into two categories: traditional pressure-sensitive adhesive tapes and silicone gel tapes. Traditional pressure-sensitive adhesive tapes are made by coating pressure-sensitive adhesive on the carrier layer. Allergy phenomenon occurs, and the skin is torn greatly when peeled off, which is easy to damage the wound; silicone gel tape solves various disadvantages of traditional pressure-sensitive adhesive tape, especially suitable for sensitive and fragile skin, and people who need to be covered for a long time; However, the current silico...
