Abstract
The invention discloses a polyurethane flame-retardant adhesive for aluminum-plastic compounding. The polyurethane flame-retardant adhesive comprises the following components in percentage by mass: 7-15% (effective addition amount) of flame retardant in polyurethane glue and 10-20% (addition amount) of surfactant in polyurethane glue. The preparation method comprises the following steps: carrying out wet grinding on the flame retardant and polyurethane glue while adding the surfactant, detecting the particle size of the flame retardant particles, and finishing grinding when the particle size of the flame retardant in the mixture is 600-1000nm, thereby obtaining the polyurethane flame-retardant adhesive. The nano sand grinder is used for finely grinding the powder flame retardant material, thereby increasing the specific area of the powder flame retardant, regulating the specific gravity of the flame retardant material, and enabling the particle size to reach nano size; and thus, the flame retardant can be suspended in the polyurethane glue without precipitation. When the polyurethane flame-retardant adhesive is used for compounding and producing the aluminum-plastic composite film, the aluminum-plastic composite film has uniform flame retardancy, and can achieve the optimal flame-retardant effect of UL94 V-0.
