Abstract

The invention relates to the technical field of edge sealing glue preparation, and discloses a preparation method and a use method of a moisture-cured polyurethane edge sealing glue with high initialadhesion. Polypropylene glycol ether, polytetrahydrofuran, amorphous polyester 7110, poly(neopentyl glycol adipate), poly(hexanediol adipate), terpene resin, copolymerized polyester resin, talcum powder and MDI are used as raw material to prepare the edge sealing glue; and the glue has the characteristics of short opening time, excellent initial adhesion, high curing speed, high peel strength, high temperature resistance, weather resistance, high-low temperature resistance, excellent water resistance, high adaptability and the like. The glue is moderate in viscosity, and is convenient to construct compared with the traditional hot melt glue.

Description

technical field [0001] The invention relates to the technical field of edge banding adhesive preparation, in particular to a method for preparing and using a moisture-curing polyurethane edge banding adhesive with high initial tack. Background technique [0002] Due to the convenient processing and high utilization rate of wood-based panels, laminated boards, density boards, particle boards, etc. can become the main materials for the building materials industry and the production of modern panel furniture. In order to increase the beautification and decorative effect of the edge of the end face of the plate, and considering that the side of the plate is loose and uneven after cutting, it is easy to absorb water and get damp, so the edge must be treated around it. Edge banding is the most widely used in the production process of panel furniture. The process is to press the edge banding strip on the edge of panel parts with adhesive, so as to play a protective and beautifying ...
