Problems solved by technology

[0003] However, even if the adhesive is widely used, the existing adhesives still cannot meet the performance requirements in some fields
For example: the mirror surface of a mirror, because the surface of the mirror surface is particularly smooth, it is difficult for existing adhesives to adhere to the surface well, and the bonding strength is not high, and the mirror surface is very easy to fall off
And the existing small amount of adhesive is applied to the mirror surface of the mirror, but it adds a large amount of organic materials, which is easy to burn. Once the temperature is slightly higher, it will cause a fire, and the consequences will be disastrous

Abstract

The invention discloses flame-retardant type glue for a mirror surface. The flame-retardant type glue is prepared from the following raw materials and components in parts by mass: 55-72 parts of polydimethylsiloxane, 4-34 parts of organosilicon polysiloxane, 35-42 parts of dimethyl silicon oil, 48-62 parts of filler, 8-14 parts of flame-retardant agent, 5-9 parts of coupling agent, 10-16 parts ofplasticizer, 3-6 parts of catalyst and 4-7 parts of antioxidant. The flame-retardant type glue for the mirror surface provided by the invention is applied to the mirror surface, and has the beneficialeffects that the cohesiveness is better, so that the mirror surface and a glue layer are not easy to drop; the glue layer has good flame retardance and can not burn even though an open fire exists, so that the safety performance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a flame-retardant adhesive for mirror surfaces. Background technique [0002] With the development of society and the continuous progress of industrial technology, the use of adhesives is becoming wider and wider. [0003] However, even if the adhesives are widely used, the existing adhesives still cannot meet the performance requirements in some fields. For example: the mirror surface of a mirror, because the surface of the mirror surface is particularly smooth, it is difficult for existing adhesives to bond well on the surface, and the bonding strength is not high, so the mirror surface is very easy to fall off. And existing a small amount of adhesive is applied on the mirror surface of mirror, but it has added a large amount of organic materials, is easy to burn, once temperature is slightly higher, will cause fire, and consequence is disastrous.
