Noise reduction and heat-insulation cement mortar and method for preparing same

Abstract

The invention discloses noise reduction and heat-insulation cement mortar and a method for preparing the same, and relates to the technical field of cement mortar. The noise reduction and heat-insulation cement mortar comprises, by weight, 75-95 parts of ordinary silicate cement, 45-55 parts of carbon fiber-graphene reinforcing agents, 25-35 parts of redispersible latex powder, 25-35 parts of ethyl acetate, 25-35 parts of ardealite, 20-25 parts of fly ash, 20-25 parts of reinforced particle compositions, 15-20 parts of polyurethane, 15-20 parts of gelatin, 5-10 parts of modified rubber powder,5-10 parts of aliphatic amine, 5-10 parts of N-sodium cocoyl sarcosinate, 5-10 parts of aluminum sulfate, 5-10 parts of water repellents, 2-6 parts of triethanolamine and 100-120 parts of water. Thenoise reduction and heat-insulation cement mortar and the method have the advantages that excellent noise reduction and heat-insulation effects can be realized by the noise reduction and heat-insulation cement mortar, the noise reduction and heat-insulation cement mortar is high in abrasion resistance, chemical corrosion resistance, strength and impact strength, good in toughness and convenient toconstruct, and the like.

Description

technical field [0001] The invention relates to the technical field of cement mortar, in particular to a noise-reducing and heat-retaining cement mortar and a preparation method thereof. Background technique [0002] Existing building materials such as cement mortar are widely used due to their easy construction and high strength. However, with the improvement of user needs, the requirements for sound insulation performance of building materials are getting higher and higher. Sound insulation materials generally require high density and large thickness. At present, the density of composite building materials on the market is small, and the sound insulation effect is not obvious after the construction is completed. In order to achieve the purpose of sound insulation, it is often achieved by adding sound insulation cotton or sound insulation layer to the wall of the building, which is expensive and increases the difficulty of construction. . As people's awareness of environme...
