Aging-resistant single-component epoxy resin-based building sound-insulation glue and making method thereof

Abstract

The invention discloses aging-resistant single-component epoxy resin-based building sound-insulation glue which is prepared from the following raw materials in parts by weight: 61-63 parts of E-44 epoxy resin, 18-20 parts of rosin, 9-11 parts of starch, 0.2-0.4 part of zinc stearate, 12-14 parts of blast furnace slag, 0.02-0.03 part of aluminum powder, 0.1-0.2 part of an ultraviolet light absorber, 0.2-0.4 part of silicon carbide, 1.3-1.6 parts of methacrylic acid-2-hydroxyethyl ester, 4-6 parts of vinyl acetate, 2.2-2.3 parts of dimethyldichlorosilance, 5-7 parts of amide, 84-86 parts of a mixed solvent and a proper amount of water; the building sound-insulation glue prepared by taking the rosin-modified epoxy resin as a matrix, adding the modified blast furnace slag, matching other effective auxiliaries and compounding with one another is convenient to operate and has the advantages of being good in anti-aging elasticity, good in bonding property, excellent in shock resistance, high in drying speed and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an aging-resistant single-component epoxy resin-based building sound insulation adhesive 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 chemical buil...

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.
