Single-component epoxy-resin-based building sound insulation adhesive high in corrosion resistance and bonding strength and preparation method thereof

Abstract

The invention discloses a single-component epoxy-resin-based building sound insulation adhesive high in corrosion resistance and bonding strength. The building sound insulation adhesive is prepared from, by weight, 55-57 parts of E-44 epoxy resin, 18-21 parts of epoxy acrylate resin, 0.02-0.05 part of aluminum powder, 10-13 parts of straw ash, 1.4-1.6 parts of oxidized paraffin soap, 1-2 parts of zirconium oxide, 7-9 parts of acrylic emulsion, 0.1-0.3 part of tea saponin, 0.5-0.7 part of 1, 2, 3-benzotriazole, 6-7 parts of tetraethylenepentamine, 1.8-2.2 parts of perfluorooctyl triethoxysilane, 9-12 parts of sticky rice starch, 1.3-1.5 parts of soybean oil, 82-84 parts of mixed solvent and a proper amount of water. The epoxy resin modified with the epoxy acrylate resin serves as a base body, the modified straw ash is added, and other effective auxiliary agents are compounded; the obtained building sound insulation adhesive is good in corrosion resistance and high in bonding strength, impact strength and shearing strength; and after being applied through brushes uniformly, the building sound insulation adhesive does not crack or generate residues and is impermeable to water.

Description

Technical field [0001] The invention relates to the technical field of adhesives, in particular to a single-component epoxy resin-based building sound-insulating adhesive with high corrosion resistance and high bonding strength and a manufacturing method thereof. Background technique [0002] With the rapid development of China'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, epoxy resin-based adhesives are used Widely used in the field of construction, especially the rapid development of the application as a structural adhesive. Its application range has expanded from home decoration, building repair and reinforcement to the construction of new buildings, and from general construction to roads, bridges, high-speed rail, and Water conservancy, airports and many other fields have become a new type of important che...

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.
