Problems solved by technology

However, this kind of glass glue is often added with harmful substances such as formaldehyde, which is more polluting when used in interior decoration, and the adhesive has poor cohesiveness, takes a long time to solidify, and the viscosity is insufficient, especially when the temperature is high. It is greatly reduced, which is not conducive to the forming of plywood, the strength after forming is insufficient, the waterproof effect of the adhesive is poor, and the produced products are easy to crack after rain, resulting in low service life

Abstract

The invention provides a glass adhesive and a preparation method thereof and relates to the technical field of adhesives. The glass adhesive is prepared from the following raw material components in parts by weight: 100-120 parts of UF (urea-formaldehyde) resin, 10-20 parts of bentonite, 3-4 parts of metallic soap, 30-40 parts of starch, 5-6 parts of dimethyl carbonate, 6-10 parts of a curing agent, 30-50 parts of filler, 4-6 parts of a modifier and 90-110 parts of water. The preparation method comprises the following steps: 1) adding UF resin, coal tar, metallic soap, alkanolamide and water to a mixer for sufficient stirring and adhesive mixing; 2) adding the starch and the filler for stirring until no air mass is left in the mixer; 3) adding the curing agent to be stirred for 5-10 minutes, and then leaving the mixture to stand for 15 minutes; 4) adding the modifier for mixing finally. The glass adhesive has the advantages of good thermosetting property, high viscosity, high strength, good endurance, good waterproof effect and long service life, and is not easy to degenerate or crack.

Description

[0001] Technical field: [0002] The invention relates to the technical field of adhesives, in particular to a glass adhesive and a preparation method thereof. [0003] Background technique: [0004] Existing glass glue is a kind of adhesive commonly used in households, and its main components are sodium silicate (Na2O·mSiO2), acetic acid and organic silicone. Sodium silicate is easily soluble in water and has viscosity. It is also called sodium silicate in the south and sodium silicate in the north. But this kind of glass glue is often added with harmful substances such as formaldehyde, which is more polluting when used in interior decoration, and the adhesive has poor cohesiveness, takes a long time to solidify, and the viscosity is insufficient, especially when the temperature is high. It is greatly reduced, which is not conducive to the forming of plywood, the strength after forming is insufficient, the waterproof effect of the adhesive is poor, and the produced products a...
