Adhesive special for heat-insulation sound-absorbing heat-isolation fiber coating and preparing method

Abstract

The invention discloses a method for preparing an appropriative bonding agent for fiber spraying, which is insulating, absorb in sound adiabatic. It consists of pure acrylic ester emulsion, acrylic acid associative thickeners, water soluble trochaic ammine, burning retardant, dim ethyl, diamino,1-propanol, multifunction substance and purified water. After mixing them and stirring, comes the bonding agent. It has many advantages: high binding strength, high resistively against water and hydrophobic after dryness or film formation, high flame retardancy, atoxigenic and flavorless and resistant to corrosion, etc. Besides, it is low-cost, high-performance, and easy to generalize.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a special adhesive for thermal insulation, sound absorption and thermal insulation fiber spraying and a preparation method thereof. 2. Background technology [0002] Binder is the main raw material used in thermal insulation fiber spraying construction. It is sprayed by the nozzle of the fiber spraying machine and mixed evenly with the heat-insulating fiber in an instant, and the heat-insulating fiber is bonded to the surface of the object to be sprayed in a three-dimensional state to form a sprayed layer, which plays a role in thermal insulation, sound absorption and sound insulation for the object to be sprayed. role. The adhesives currently used are all water-based adhesives, and the following problems occur during use: 1. The bonding strength is low. During spraying construction or when the sprayed layer is in a wet state, local peeling and adhesive ...

AI Technical Summary

Problems solved by technology

The adhesives currently used are all water-based adhesives, and the following problems occur during use: 1. The bonding strength is low. During spraying construction or when the sprayed layer is in a wet state, local peeling and adhesive flow are prone to occur Especially when the ambient temperature is low, the peeling of the sprayed layer and the flow of the adhesive are more serious

2. The binder has poor cohesiveness in a wet state, resulting in serious rebound and flying of the fiber cotton during the spraying process, resulting in waste of materials and deterioration of the construction site environment

3. After the binder is dried and formed into a film, its water resistance and hydrophobicity are poor, and the sprayed layer will fall off when the ambient humidity is high (relative humidity above 90%)
