Abstract

The invention discloses a cement-based sound insulation leveling adhesive material for an overall sound insulation floor. The adhesive material is formed by dry mixing of the following raw materials by mass: 55%-70% of cement, 20%-30% of a vibration reduction and sound insulation component, 1%-5% of a sound absorption and insulation component, 0.3%-0.7% of a stress dispersion component, 5%-13% of a reinforcement component, 0.3%-0.9% of a tackifying assistant, 0.1%-0.5% of a water retention assistant, and 0.1%-0.2% of an anti-cracking assistant. The invention also relates to a preparation method of the cement-based sound insulation leveling adhesive material. The cement-based sound insulation leveling adhesive material provided by the invention has good bonding properties and deformation resistant ability, is used for making a sound insulation leveling layer of the overall sound insulation floor, can realize direct laying of a surface layer thereon according to the ordinary decoration practice, and can form good cementation both with the floor and the surface layer material, thus reaching the overall sound insulation effect.

Description

technical field [0001] The invention relates to a building sound insulation cushion material, in particular to a cement-based sound insulation leveling adhesive material for an integral sound insulation floor. Meanwhile, the invention also relates to a preparation method of the adhesive material. Background technique [0002] The sound insulation cushion materials of the traditional floating sound insulation floor system are mostly low-strength materials, such as cross-linked polyethylene rubber pads, extruded polystyrene boards, rock wool boards, etc., which do not have bearing capacity, and the sound insulation cushion materials are different from There is no effective bonding between the floor and the surface, so it is necessary to make 40-50mm reinforced concrete or reinforced fine stone concrete on the cushion (Note: 40mm reinforced layer is the minimum requirement for this type of floating floor at home and abroad), The total thickness of the sound insulation layer st...
