Problems solved by technology

[0007] That is to say, ointments and gels generally use ointment base or gel base to load drugs and apply them to the affected area to play a therapeutic role. Due to the existence of the base, they will not dry under normal circumstances and are easy to be damaged during artificial contact with the outside world. Wipe off, thereby reducing the application time, and because it does not have good physical isolation properties, the affected area is easy to be infected or polluted during use
Composite material dressings in the field of medical materials often have shortcomings in adaptability, application time and tightness due to their poor conformability and hard film quality

Abstract

The invention belongs to the technical field of coating agents and particularly relates to a medical repair coating agent and a preparation method thereof. The coating agent is prepared from 8-35% ofa biological adhesive material, 3-18% of a plasticizer, 0.1-5% of active substances, 0.05%-0.5% of a bacteriostatic agent, 0.5-10% of an emulsifier, 0.5-8% of grease and the balance purified water, wherein the effective substances are at least one of micromolecule sodium hyaluronate, scutellaria root extract, salvia miltiorrhiza extract, trimethylglycine, allantoin and glucosamine. The coating agent is short in film-forming time, good in ductility and easy to apply, and a film formed after application has good toughness without cracking, tearing and the like; the adhesion property of the filmis proper, when the film is removed at the end of action, the comfort is high, and the conditions of skin pain, secondary wound cracking and the like in the pulling process are avoided.

Description

technical field [0001] The invention belongs to the technical field of coating agents, and in particular relates to a medical restoration coating agent and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the maintenance of appearance. Cosmetics, as a means of skin maintenance, are used by more and more people. However, due to market misleading or improper use of skin care products, causing People, especially teenagers, have excessive skin care behaviors, such as excessive cleaning, excessive application of masks to cause excessive skin hydration, excessive exfoliation of the stratum corneum, resulting in too thin stratum corneum, etc., resulting in a certain degree of damage to the skin barrier, while the skin barrier structure and Dysfunction is associated with a variety of skin problems. [0003] The skin barrier is mainly composed of stratum corneum, structural lipids and...
