Abstract
The invention discloses a hot-vulcanization single-component silicone rubber sealing adhesive. The silicone rubber sealing adhesive is prepared from raw materials in parts by weight as follows: 50-150 parts of methyl vinyl silicone rubber, 40-80 parts of packing, 1-20 parts of a tackifier and 0.5-2 parts of a curing catalyst. The silicone rubber sealing adhesive has good joint strength at a high temperature and also has better elasticity, and the implementation process is good. The adhesive is mainly used for improving adhesive properties of different materials, such as adhesion of glass, metal and plastic as well as fastening and combining metal parts in machinery manufacturing.
Description
Technical field
The invention belongs to chemical technology field, relate to a kind of silicone rubber seal tackiness agent, be specifically related to a kind of hot sulfurization single-component silicone rubber seal tackiness agent.
Background technology
Along with industrial expansions such as space travel, aircraft manufacturing and electronics, require to have novel fire resistant rubber and high-temperature-resistant adhesive.Silicon rubber is used widely because having good thermostability, good winter hardiness, good electrical property and excellent weathering resistance; Silicone rubber adhesive, shortcoming is that cohesive strength is low, a little less than adhesive power, but can improve adhesion strength and cohesive strength by adding filler to carry out reinforcement, now as non-structural adhesive, is used widely.
Hot sulfurization single-component silicone rubber adhesive is comprised of single-component organic silicon macromolecular compound, there are stripping strength, cementability, lap shear strength and high temperature to protect the feature of the multifrequency nature overall balance performances such as viscosity, are applicable to not sulphurated siliastic and metal (stainless steel, steel, copper etc.), resin, glass fibre, ceramic bonding hot vulcanization.
The formula of silicone rubber adhesive is similar with silicon rubber, mainly comprises rubber, filler, solidifying agent, tackifier, oxidation inhibitor, thermo-stabilizer and tinting material etc.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of hot sulfurization single-component silicone rubber seal tackiness agent that has good adhesivity and water tolerance is provided.
Above-mentioned purpose of the present invention is achieved by the following scheme:
A kind of hot sulfurization single-component silicone rubber seal tackiness agent, described tackiness agent is made by the raw material of following weight part:
