Embodiment 1

[0033] Such as figure 1 As shown, a preparation method of a silicone gel scar patch with adjustable viscosity comprises the following steps:

[0034] Step (1), preparation of semi-cured silicone gel: evenly coat the silicone gel on the template A, let it stand at room temperature 25°C until the bubbles are completely precipitated, and then heat the template A to half of the silicone gel. solidified state, then stop heating and cool to obtain semi-cured silicone gel;

[0035] Step (2), preparation of silicone gel films with different viscosities on both sides: positively press the template B brushed with a release agent on the semi-cured silicone gel after step (1), heat until it is completely cured, and remove the template A and template B, the reverse structure of the micro-nano array structure prepared on the template can be transferred to the colloidal film to obtain a silicone gel film with different viscosities on both sides;

[0036] Step (3), preparation of silicone g...

Embodiment 2

[0038] Determination of curing time and temperature of silicone gel with fixed ratio:

[0039] Coat the silicone gel evenly mixed according to a certain ratio (polymethylsiloxane: curing agent = 3:1) on the common template, and let it stand at room temperature 25°C for 2 hours until the bubbles are separated and distributed. After uniformity, put the ordinary template on the heating plate and heat it at a temperature of 40°C until the silicone gel is completely cured, and measure the time required for complete curing.

[0040] The measured results showed that the curing time was 8 hours.

Embodiment 3

[0042] Determination of curing time and temperature of silicone gel with fixed ratio:

[0043] Coat the silicone gel evenly mixed according to a certain ratio (polymethylsiloxane: curing agent = 9:1) on the common template, and let it stand at room temperature for 2 hours at 25°C until the bubbles are separated and distributed. After uniformity, put the ordinary template on the heating plate and heat it at a temperature of 100°C until the silicone gel is completely cured, and measure the time required for complete curing.

[0044] The measured results show that the curing time is 30min.

Abstract

The invention discloses a viscosity-adjustable silica gel scar patch and a preparation method thereof, and belongs to the technical field of medical cosmetology, and the preparation method of the viscosity-adjustable silica gel scar patch comprises the following steps: step (1) preparing semi-cured silica gel; step (2) preparing a silica gel film with two side surfaces having different viscosities; and step (3) preparing the silica gel scar patch. In order to solve the technical problem that the viscosity difference of the inner surface and the outer surface of silica gel is difficult to coordinate in the prior art, the viscosity of the silica gel scar patch is controlled by regulating micro-nano bulges on the surface of the silica gel scar patch, so that the viscosity difference of the inner surface and the outer surface of the silica gel is controlled; the control method is that: transferring micro-nano-level structures on different surfaces of the template A and the template B to the inner surface and the outer surface of the silica gel; no solution participates in the transfer printing process, no residual silica gel treatment process exists, the operation is easy and fast, and the cost-effectiveness is high.

Description

technical field [0001] The invention belongs to the technical field of medical cosmetology, and in particular relates to a silicone gel scar patch with adjustable viscosity and a preparation method thereof. Background technique [0002] After the human body is damaged by trauma, especially in the self-repair process after surgery, scar hyperplasia may be accompanied by the formation of scar hyperplasia, which mostly occurs on the face, neck, limbs and trunk of patients, which not only affects the physiological functions of the skin, but also Affect the beauty of the patient, and seriously cause the psychological shadow in the patient's heart. Therefore, it is necessary to adopt scientific and effective methods to treat and prevent scar hyperplasia, which has also attracted more and more people's attention. How to prevent and treat scar hyperplasia has always been a hot topic in the field of wound repair, but there is no effective method for the prevention and treatment of s...
