Tensile single-component epoxy resin based building sound isolation rubber and preparation method thereof

Abstract

The invention discloses tensile single-component epoxy resin based building sound isolation rubber which is prepared from the following raw materials in parts by weight: 59 to 60 parts of E-44 epoxy resin, 21 to 24 parts of waste polystyrene foamed plastic, 0.02 to 0.05 part of aluminum powder, 1 to 3 parts of glass fiber, 12 to 15 parts of sepiolite powder, 0.3 to 0.5 part of ammonium persulfate, 1.2 to 1.4 parts of cashew nut shell oil, 0.9 to 1.3 parts of nano calcium carbonate, 3 to 5 parts of triethylene tetramine, 1.7 to 2.1 parts of (3-aminopropyl) diethoxy ethyl silane, 4 to 6 parts of kelp mucus, 8 to 12 parts of corn starch, 83 to 86 parts of a mixing solvent and a proper amount of water. The waste polystyrene foamed plastic modified epoxy resin is used as a base body, the modified sepiolite powder is added and cooperated with other effective adjuvants, so that the prepared building sound isolation rubber has the characteristic of being quickly dissolved in cold water or warm water, can be mixed with various building materials such as gypsum for use, and has the advantages of tensile strength, drop resistance, water resistance, moisture retention, thickening, high constructability and the like.

Description

technical field

[0001] The invention relates to the technical field of adhesives, in particular to a tensile 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 building mate...
