Abstract

The invention provides a high temperature-resistant heat activated adhesive and a preparation method thereof and belongs to the field of adhesive liquids. The high temperature-resistant heat activated adhesive solves the problem that the existing preparation technology has poor resistance to a high temperature. The high temperature-resistant heat activated adhesive comprises, by mass, 33-35% of aromatic polyester-type polyurethane, 0.6-0.8% of an additive, 12-30% of butanone and 33-53% of cyclohexanone. The preparation method comprises A, preparing 33-35% of aromatic polyester polyurethane, 0.6-0.8% of the additive, 12-30% of butanone and 33-53% of cyclohexanone on the basis of mass, and B, heating the standby cyclohexanone, aromatic polyester-type polyurethane and additive at a rotation rate of 3000-4000 r / min to 50-70 DEG C for melting for 2-3h to obtain an adhesive semi-finished product. The high temperature-resistant heat activated adhesive has good heat resistance.

Description

technical field [0001] The invention belongs to the technical field of glue, and relates to a high-temperature-resistant heat-activated glue, in particular to a high-temperature-resistant heat-activated glue used for warning labels of sun visors. Background technique [0002] Now the auto industry has mandated that sun visor warning labels be posted on both sides of the sun visor. At the same time, the vehicle factory must meet the requirements for the warning label of the sun visor: high temperature resistance of 90 degrees for 168 hours. [0003] The existing common sun visor warning labels have the following defects: [0004] Ordinary self-adhesive labels: the glue is solvent-based. Under high temperature conditions: there will be solvent volatilization in the car that does not reach the car VOC standard. Secondly, the solvent-based glue will melt, overflow, and fall off easily, which cannot meet the high temperature conditions in the car. [0005] Its publication numbe...
