Sealing adhesive for mounting mirror

Abstract

The invention discloses a sealing adhesive for mounting a mirror. The sealing adhesive is prepared from, by weight, 40-60 parts of vinyl acetate resin, 60-80 parts of an organopolysiloxane polymer, 60-80 parts of a filler, 0.4-1 part of a thixotropic agent, 2-6 parts of a coupling agent, 0.2-0.6 part of a catalyst, 2-6 parts of a defoaming agent, 2-4 parts of a toughening agent and 2-4 parts of awaterproof agent. The adhesive overcomes the defects in the prior art, can seal a mirror and a mirror frame tightly and prevent insects and ants from entering the frame, has a mildew-proof function, and can prevent bacteria and viruses from breeding between the mirror and the mirror frame. Meanwhile, by adding a perfluoro-hydroxyl carbon-silicon copolymer, a stable invisible waterproof molecular coating film can be formed on the basis of the ultralow surface tension of the perfluoro-hydroxyl carbon-silicon copolymer and has excellent lasting water repellency and oil repellency effects on moisture and oil stains.

Description

technical field

[0001] The invention relates to the technical field of adhesives, in particular to a sealing adhesive for mirror mounting. Background technique

[0002] There is a saying: a husband uses copper as a mirror to correct his clothes, history as a mirror to know the ups and downs, and man as a mirror to know the gains and losses. Mirrors are a necessity for life and work, and they 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 frame, the existing technology is to block the mirror by setting a positioning slot, 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 frame, and it is very unhygienic. It is easy to breed viruses. Contents o...
