Anti-seepage single-component epoxy resin-based building sound insulation glue and production method thereof

Abstract

The invention discloses anti-seepage single-component epoxy resin-based building sound insulation glue. The sound insulation glue is prepared from the following raw materials in parts by weight: 61-64 parts of E-44 epoxy resin, 17-19 parts of terpene resin, 7-8 parts of triethylene tetramine, 15-17 parts of coal ash, 0.01-0.03 part of aluminum powder, 2.1-2.3 parts of chitosan, 4-6 parts of polyester fiber, 1.6-1.8 parts of N-vinyl pyrrolidone, 0.7-0.9 part of methyl ethyl ketone peroxide, 0.9-1.2 parts of epoxidized soybean oil, 2.5-2.7 parts of urea propyl triethoxysilane, 10-12 parts of konjaku flour, 81-82 parts of a mixed solvent and a proper amount of water. The terpene resin modified epoxy resin is taken as a matrix and is added with modified coal ash and is compatible with other effective aids to obtain the building sound insulation glue. The building sound insulation glue has good cohesiveness and high shock resistance and shear strength, is applicable to the surface adhesion of cement, green red bricks, glass, wood and the like and further has the good properties of seepage resistance, acid-alkali resistance and ultraviolet ray resistance after being thoroughly dried by 7 days.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a single-component epoxy resin-based building sound insulation adhesive capable of preventing leakage and a production method thereof. Background technique [0002] With the rapid development of my country's construction industry, new building materials are constantly being developed and applied. In order to meet the bonding requirements of most building materials such as stone, wood, concrete, metal, ceramics and glass, the adhesive with epoxy resin as the main body is being used. Widely used in the field of construction, especially as a structural adhesive, the application has developed rapidly. Its application range has expanded from home decoration, building repair and reinforcement to new building construction, and has developed from general construction to roads, bridges, high-speed rail, Water conservancy, airports and many other fields have become a new type of important ...

Problems solved by technology

[0005] However, in this paper, expandable graphite is used as the flame retardant material. The high cost is not conducive to mass production, and with the expansion of the application field, the requirements for construction adhesives are getting higher and higher. In addition to mechanical properties, bonding properties, flame retardant properties and other requirements In addition, for the convenience of construction, users prefer single-component adhesives, which do not require on-site weighing, configuration, mixing and other processes, which can improve work efficiency; in addition, with the improvement of people's quality of life, in addition to requiring long life and weather resistance of buildings, etc. In addition, people have higher and higher requirements for the living environment, especially for building sound insulation and noise reduction. Therefore, it is necessary to modify the existing construction adhesives. On the basis of ensuring its comprehensive performance, add corresponding additives to improve the adhesive properties. Therefore, it is necessary to modify the waste residue produced by industrial production, optimize the formula to improve the existing production process, and develop a single-component epoxy resin-based building sound insulation adhesive with sound insulation function.
