Abstract

The invention discloses a PUR fitting hot melt adhesive for a door pocket line of a robot operation wooden door, which is prepared from the following raw materials in parts by weight: 50 to 70 parts of polyester polyol, 20 to 30 parts of polyether polyol, 15 to 30 parts of tackifying resin, 15 to 25 parts of isocyanate, 1 to 3 parts of an antioxidant, 1 to 5 parts of a flame retardant and 1 to 5 parts of hydrophobic nano silicon dioxide. The prepared PUR laminating hot melt adhesive has long opening time, good initial viscosity and high initial adhesion strength and final adhesion strength. And the automatic operation of a full-automatic robot on the wooden door wood sleeve line can be met, so that the working efficiency and the laminating quality are improved.

Description

technical field [0001] The invention belongs to the technical field of hot-melt adhesives, and in particular relates to a PUR-laminated hot-melt adhesive for robot-operated wooden door casings and a preparation process thereof. Background technique [0002] Moisture-curing reactive polyurethane (PUR) hot-melt adhesive has the advantages of high bonding strength, good flexibility, good weather resistance, wide range of applicable materials, environmental protection and no pollution. It has developed rapidly in recent years and has become an important hot-melt adhesive product. A big category. This product is more and more widely used in the fields of fabric bonding, furniture edge banding, home appliance assembly, electronic assembly, etc. The curing process of conventional reactive polyurethane hot melt adhesives is generally divided into two steps. The first step is physical curing, which increases the cohesive strength of the material by lowering the temperature of the gl...
