Problems solved by technology

[0003] Plexiglass is a polymer obtained by polymerization of acrylic acid and its esters. Plexiglass has excellent light transmission properties, high mechanical strength, corrosion resistance, and easy processing, but its texture is brittle and easily soluble in organic solvents. The surface hardness is not enough, easy to rub hair, etc.
Because of its brittle texture, plexiglass needs to use adhesives when combined with other products, but the adhesives currently used have poor bonding effect and poor resistance to acid and alkali

Abstract

The invention discloses a glass adhesive and a preparation method thereof. The glass adhesive is prepared from ethyl cyanoacrylate, polyvinyl acetate, hydroxypropyl methylcellulose, stearic acid, pentamethyldiethylenetriamine, dimethyl sebacate, tricalcium phosphate, silica, glass frit, dioctyl phthalate and azodicarbonamide. The preparation method comprises the following steps: stirring and mixing the polyvinyl acetate, hydroxypropyl methylcellulose, dimethyl sebacate, tricalcium phosphate and glass frit to obtain a first mixture, adding the first mixture into a reactor, adding stearic acid and azodicarbonamide under a vacuum condition, and performing heating and stirring to obtain a first material; adding the ethyl cyanoacrylate, pentamethyldiethylenetriamine, silica and dioctyl phthalate to the first material, and performing heating and stirring under the protection of an inert gas to obtain the glass adhesive. The glass adhesive provided by the invention has the advantages of goodadhesion and good resistance to acids and alkalis.

Description

technical field [0001] The invention belongs to the technical field of adhesive preparation, and in particular relates to a glass adhesive and a preparation method thereof. Background technique [0002] Glass is usually divided into oxide glass and non-oxide glass according to the main components. There are few varieties and quantities of non-oxide glasses, mainly chalcogenide glasses and halide glasses. The anions of chalcogenide glass are mostly sulfur, selenium, tellurium, etc., which can cut off short-wavelength light and pass through yellow, red light, and near and far infrared light. It has low resistance and has switching and memory characteristics. Halide glass has low refractive index and low dispersion, and is often used as optical glass. [0003] Plexiglass is a polymer obtained by polymerization of acrylic acid and its esters. Plexiglass has excellent light transmission properties, high mechanical strength, corrosion resistance, and easy processing, but its tex...
