Problems solved by technology

However, the elastic film has low adhesive force and weak mechanical strength on the skin surface.
When thin coating is applied to meet the invisible function, the coating film is easy to break and fall off from the surface, and the service life is not as good as that of traditional artificial skin materials

Abstract

The invention discloses high-strength elastic invisible artificial skin and relates to the field of fine chemistry. The high-strength elastic invisible artificial skin is prepared from a component A and a component B, wherein the component A is prepared from vinyl silicone oil, vinyl modified silicon dioxide particles, a chitosan vinyl derivative and hydrogen-containing silicone oil; the componentB is prepared from a platinum catalyst, silicone oil, a matting agent and a wetting agent. The invention further discloses a production method of the high-strength elastic invisible artificial skin;the preparation method comprises the following steps: preparing the component A, preparing the component B and preparing a coating film. After the component A and the component B are coated, the component A and the component B can be rapidly crossly linked to form the film at room temperature, so that the high-strength elastic coating film is formed and the elasticity of the skin is recovered instantly; the color of the coating film is similar with the color of the skin and the stealthiness is good. The coating film also has a relatively good adhesive force, waterproof performance and scrubbing resistance, and daily washing of the skin is not influenced. In addition, the elastic coating film has relatively high strength and can be peeled from the surface of the skin.

Description

technical field [0001] The invention relates to the field of fine chemistry, in particular to a high-strength elastic invisible artificial skin and a manufacturing method thereof. Background technique [0002] The human skin is in direct contact with the environment and is a barrier to protect the human body from external aggressions. With age, the skin will gradually lose its elasticity, and aging phenomena such as wrinkling, sagging, and stains will occur, especially the skin aging on the exposed external skin such as the face and hands will seriously affect people's image. Therefore, there is an urgent market demand for skin beauty and health care. At present, there are two ways to perform beauty treatment on the face in the market. One is liposuction and injection. This method has quick results, but it will cause harm and cause irreversible skin damage. For example, repeated liposuction for eye bags will make the eye circles black and sagging gradually serious, eventua...
