Abstract

The invention provides a tackifier composition for addition type silica gel. The tackifier composition is prepared from the following raw materials in parts by weight: 100 parts of silane containing epoxy group or siloxane oligomer and 0.01-5 parts of photo-acid generator. The invention also discloses an application method of the tackifier composition for addition type silica gel. The application method specifically comprises: mixing two raw materials of the tackifier composition and adding the mixed raw materials in the addition type silica gel, or respectively adding the two raw materials in the two components of the addition type silica gel. The tackifier composition for addition type silica gel provided by the invention has the advantages of simple process, simple application method, good versatility, no effect on curing performance of the silica gel and no effect on storage stability of liquid cement.

Description

technical field [0001] The invention relates to a tackifier, in particular to a tackifier composition for addition-type silica gel and its application. Background technique [0002] Addition-type silica gel has incomparable advantages in performance compared with condensation-type silica gel: better mechanical properties; no release of small molecules, will not affect bonding materials and other components; lower shrinkage, better dimensional stability; The performance is better and more stable, and there is basically no change during and after curing. Although the addition type has better comprehensive performance, it also has some disadvantages, such as general adhesion, and poor adhesion to most substrates, which limits its application to a large extent. When potting, coating, adhesive fixing and other materials are used, in order to improve the adhesion with the contact substrate, it is usually necessary to pre-coat the substrate or add a tackifier.
