Problems solved by technology

Existing silicone nipple stickers generally achieve adhesiveness by adding methyl silicone oil to ordinary silicone rubber or coating the surface with glue. When only methyl silicone oil is used, the viscosity is poor when the time is long, especially methyl silicone oil. When the added amount is insufficient, the viscous supply is insufficient. If the content of methyl silicone oil is increased, the product will cause oil separation, which will affect the use effect
Although applying glue on the surface of silicone rubber can satisfy good viscosity, the production process is complicated, and the solvent in the glue can easily cause skin allergies and cannot be reused

Abstract

The invention discloses self-adhesive solid silicone rubber, which is prepared from the following materials in parts by weight: 100 parts of raw methyl vinyl silicone rubber, 10-50 parts of white carbon black, 2-10 parts of hydroxyl silicone oil, 1-30 parts of methyl silicone oil, 0.05-0.5 parts of zinc stearate, 1-20 parts of a tackifier, 0.1-1 part of a platinum catalyst and 0.1-1 part of a cross-linking agent. The tackifier has adhesiveness and is compatible with the raw methyl vinyl silicone rubber, and the tackifier is a mixture of vinyl silicone resin and hydroxyl silicone resin. The self-adhesive solid silicone rubber provided by the invention has the advantages of no oil separation, reusability, good rebound resilience, soft hand feeling, good skin adhesiveness, safety and environment-friendliness. The invention also provides a preparation method of the self-adhesive solid silicone rubber and an application of the self-adhesive solid silicone rubber in silica gel breast stickers.

Description

Technical field[0001]The present invention relates to the field of silicone rubber, and more particularly to a self-adhesive solid silicone rubber and a preparation method thereof.Background technique[0002]Silicone rubber has excellent high temperature resistance, safe environmental protection, non-toxic and tasteless, good gas permeability, oxygen transmittance is the highest in synthesis polymers, and has excellent physiological inert, and does not cause prone or allergies. Widely used in medical, daily necessities and other industries, good contact with human body, such as used for milk stickers. The existing silica gel stickers are generally pasted by adding methyl silicone oil or surface coating glue in ordinary silicone rubber. When only methyl silicone oil is used, when the time is longer, the viscosity is poor, especially methyl silicone oil. When the addition is insufficient, the viscosity provides insufficient, and if the content of the methyl silicone oil can cause the pr...
