Abstract

The invention discloses a sealing adhesive for a mirror. The sealing adhesive is prepared from the following raw materials in parts by mass: 45 to 80 parts of vinyl acetate resin, 60 to 85 parts of organic polysiloxane polymers, 55 to 90 parts of fillers, 0.3 to 0.8 part of a thixotropic agent, 1 to 4 parts of a coupling agent, 0.1 to 0.4 part of a catalyst, 2 to 7 parts of a defoaming agent and 1to 3 parts of a flexibilizer. The sealing adhesive for the mirror, disclosed by the invention, is applied to a part between the mirror and a mounting frame of the mirror and can tightly seal the mirror and the mounting frame of the mirror, so that insects and termites are prevented from entering the frame, and further the service life of the fitting frame is prolonged; in addition, the sealing adhesive has a mold-proof function, thereby preventing bacteria and viruses from being generated between the mirror and the fitting frame of the mirror.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a mirror sealing adhesive. Background technique [0002] There is a saying: A husband uses copper as a mirror to straighten his clothes, history as a mirror to know the ups and downs, and man as the mirror to know the gains and losses. [0003] Mirrors, as a necessity for life and work, are used in various fields. In life, mirrors can be seen everywhere, but as a separate item, mirrors often need to cooperate with other items. For example: When a mirror is framed, it is often matched with aluminum alloy or plastic. In order to prevent the mirror from moving in the mounting frame, the prior art is to block the mirror by setting positioning slots, but because of the existence of gaps in the frame, it is very easy for insects and ants to enter, resulting in a greatly reduced service life of the mounting frame, and it is very uncomfortable. Hygienic, easy to breed viruses. Con...
