Abstract

The invention discloses a sound insulation adhesive and a preparation process thereof. The sound insulation adhesive is prepared from the following components in percentage by mass: 10 to 15 percent of an asphalt waterproof emulsion, 1 to 3 percent of a water-based elastic emulsion, 5 to 8 percent of a PTFE emulsion, 1 to 5 percent of an acrylic emulsion, 5 to 10 percent of inorganic gel, 0.5 to 1 percent of aerogel, 60 to 65 percent of barite powder, 4 to 8 percent of an additive and 1.5 to 5 percent of an adjuvant. According to the invention, a mixed emulsion solution and some materials with special properties are fully utilized for matching, so the sound insulation adhesive has considerable improved excellent targeted properties including fire prevention, water prevention, high temperature resistance, low temperature resistance, high flexibility, sound insulation, radiation protection, vibration reduction and the like; and the sound insulation adhesive is simple in manufacturing process and convenient to construct, and can be used for directly filling and plugging gaps of doors and windows in virtue of a glue gun.

Description

technical field [0001] The invention relates to building sound-absorbing materials, in particular to a sound-insulating glue and a preparation process thereof. Background technique [0002] In order to facilitate the installation of doors and windows, holes are often reserved at the installation positions of doors and windows during the construction process, resulting in the formation of redundant gaps after the installation of doors and windows. Therefore, caulking and sealing have become an important link in the installation of doors and windows. The quality of caulking and sealing materials is one of the most important factors affecting the quality of doors and windows engineering. The commonly used joint filling materials are cement mortar, glass fiber, rock wool, wool top, silicone glue, polysulfide sealing material, polyurethane sealing material, etc. Ordinary cement mortar has poor bonding force, poor deformation ability, and is easy to shrink and crack; it is sealed...
