Stone adhesive and preparation method thereof

Abstract

The invention discloses a stone adhesive. The stone adhesive is characterized in that alpha-ethyl cyanoacrylate is taken as a main body, and components also comprise a pyrogallic acid ester compound and titanium dioxide, wherein the mass of pyrogallic acid esters accounts for 500-800 ppm of the mass of the alpha-ethyl cyanoacrylate; the mass of the titanium dioxide accounts for 500-1000 ppm of themass of the alpha-ethyl cyanoacrylate. Compared with the prior art, the stone adhesive has the advantages that 1, the stone adhesive can permeate into marble gaps due to small viscosity and good permeability; 2, the dried stone adhesive is large in bonding strength and good in stability; 3, the stone adhesive does not yellow either after being placed for a long time; 4, a preparation technology is simple and easy to operate.

Description

Technical field [0001] The invention relates to the technical field of α-ethyl cyanoacrylate adhesives, in particular to a stone adhesive and a preparation method thereof. Background technique [0002] In 1947, A·E·Ardis first synthesized α-cyanoacrylate and obtained a patent. In the 1950s, Eastman Kodak researchers accidentally discovered the adhesive properties of α-cyanoacrylate and officially launched the world's first α-adhesive. Subsequently, Japan, West Germany and other countries have also been put into production. my country began to research and produce in the 1960s. The α-adhesive has developed rapidly once it came out. It has fast curing speed, convenient use, strong adhesion, and wide range of bonding materials. For bonding steel, non-ferrous metals, rubber, leather, plastics, ceramics, glass, wood, stone, etc., it is widely used in electrical, instrumentation, machinery, electronics, optical instruments, medical, light industry and civil industries.

AI Technical Summary

Problems solved by technology

The stone glue in the prior art often has the following disadvantages: 1. The dark traces at the cracks cannot be covered when the cracks are repaired, and the aesthetics after repairing the light-colored stones is poor; 2. After the adhesive is placed for a long time, the bonding 3. The bonding strength is not large, and it is often necessary to rely on the bottom plate to increase the strength during the stone repair process.
