Problems solved by technology

However, organic solvents need to be used in the production process of such products, and residual solvents may cause adverse consequences such as allergies during use. At the same time, the adhesive ability of the colloid and the skin is very small, so it does not have the application in medicine, cosmetics, health, and medical beauty industries. practicality
It can be seen that the currently published patents for silicone pressure-sensitive adhesives are not enough to fully satisfy the transdermal patch industry. Silicone pressure-sensitive adhesives are safe, non-toxic, easy to coat, well combined with common substrates, and can be quickly vulcanized and pasted. Adjustable performance, can adapt to many requirements such as rapid production

preparation example Construction

[0043] The invention also discloses a method for preparing a silicone pressure-sensitive adhesive, which specifically includes the following steps:

[0044] (1) Mix the vinyl silicone oil, filler, hydrogen-containing silicone oil and inhibitor in the formulated amount evenly to obtain Group A glue, which is set aside;

[0045] (2) Mix the vinyl silicone oil, filler and catalyst in the formula quantity evenly to obtain Group B glue, which is set aside;

[0046] (3) Mixing the group A glue and the group B glue evenly and then vulcanizing to obtain a silicone pressure sensitive adhesive.

[0047] In order to further realize the technical effect of the present invention, in step (3), the vulcanization temperature is from room temperature to 120° C., and the vulcanization time is from 3 to 10 minutes.

Embodiment 1

[0050] Take the raw material by the following parts by weight:

[0051] Component A: 45 parts of vinyl silicone oil, 0.1 part of hydrogen-containing silicone oil, 0.2 parts of inhibitor anethole, 3 parts of filler;

[0052] Component B: 45 parts of vinyl silicone oil, 0.02 parts of catalyst, and 3 parts of filler.

[0053] Mix and stir the two components A and B at a ratio of 1:1 and apply them on the backing material.

[0054] And vulcanized at 120° C. for 10 minutes to obtain the silicone pressure-sensitive adhesive disclosed in Example 1.

Embodiment 2

[0056] Take the raw material by the following parts by weight:

[0057] Component A: 48 parts of vinyl silicone oil, 0.1 part of hydrogen-containing silicone oil, 0.5 parts of inhibitor myrcene, 11 parts of filler;

[0058] Component B: 48 parts of vinyl silicone oil, 0.2 parts of catalyst, and 11 parts of filler.

[0059] The two components A and B are mixed and stirred at a ratio of 1:1, coated on the backing material, and vulcanized at 120°C for 10 minutes to obtain the silicone pressure-sensitive adhesive disclosed in Example 2.

Abstract

The invention discloses an organosilicon pressure-sensitive adhesive, and a preparation method and application thereof, belonging to the technical field of preparation of organosilicon pressure-sensitive adhesives. The organosilicon pressure-sensitive adhesive comprises the following raw materials by weight: 90-110 parts of vinyl silicone oil, 0.1-4 parts of hydrogen-containing silicone oil, 6-40parts of a filler, 0.01-10 parts of an inhibitor, and 0.02-20 parts of a catalyst. The organosilicon pressure-sensitive adhesive disclosed by the invention adopts a novel inhibitor, namely a natural aromatic substance, has higher safety and a better inhibition effect, and can effectively solve the technical problems of usage of an organic solvent, poor adhesion performance, long vulcanization timeand the like of conventional organosilicon pressure-sensitive adhesives. Because of the excellent performances of safety, no toxicity, easiness in coating, adjustable and controllable adhesion performance, rapid vulcanization, suitability for rapid production and the like, the adhesive is effectively applied to the fields of medicines, medical cosmetology and the like, and has great market application and popularization values.

Description

technical field [0001] The invention belongs to the technical field of silicone pressure-sensitive adhesives, and in particular relates to a silicone pressure-sensitive adhesive with natural aromatic substances as inhibitors, a preparation method and application thereof. Background technique [0002] At present, transdermal patches have been widely used in medicine, medical beauty, cosmetics and health industries, and are growing at a rapid rate, with extremely broad prospects. The pressure-sensitive adhesives used in traditional transdermal agents are made of polyacrylate or polyurethane. Although they are cheap and widely used, they are toxic to the skin, irritating, and have poor weather and sweat resistance, acid and alkali resistance, and oil resistance. , and when peeling off, the skin is torn relatively large, and the wound is easily damaged, which brings great discomfort and limitations to the manufacturer and the user. [0003] In addition, although the silicone ge...
