Abstract

The invention relates to the technical field of plastic uptake materials, in particular to a high-peel-strength vacuum plastic uptake material and a preparation method thereof, wherein the high-peel-strength vacuum plastic uptake material comprises the following raw materials: polycaprolactone triol, polypropylene glycol, diisocyanate, epoxidized soybean oil / modified polyacrylate mixed solution, acatalyst, acetone, a chain extender, ethylenediamine and deionized water. The vacuum plastic uptake adhesive has higher solid content and lower thermal activation temperature, so that the curing speed is higher, and the film forming time is shorter.

Description

technical field [0001] The invention relates to the technical field of plastic suction, in particular to a vacuum plastic suction with high peel strength and a preparation method thereof. Background technique [0002] Vacuum blister technology is widely used in the manufacture of computer desks, dressing tables, cabinets, door panels and furniture. The construction process is to cover the PVC film on the density board that has been dried after spraying glue, heat and soften the PVC through a vacuum suction machine and activate the plastic suction glue, use vacuum to remove the air between the PVC film and the density board film, rely on the atmosphere The pressure makes the PVC film stick tightly to the MDF. The biggest feature of this process is that it does not need to spray paint or paint. It is a paint-free process. This feature is especially important in the preparation of door panels and furniture. [0003] The adhesive used in the vacuum suction process is called va...
