Abstract

A manufacturing method of a high-strength thermosetting resin high-pressure laminated board is characterized by comprising the following manufacturing steps: 1, impregnating surface layer paper and decorative paper in a melamino-formaldehyde resin for 1.5-2 hours; 2, dissolving triglycidyl isocyanurate in a mixed solution of acetone and propionic acid at 50 DEG C, and impregnating bottom layer paper in the mixed solution for 30 min; 3, laminating the impregnated surface layer paper and the bottom layer paper impregnated with phenolic resin, and hot-pressing at 135-145 DEG C under 7-10 MPa pressure for 40-50 min. The manufacturing method has the advantages that as the bottom layer paper is impregnated with the triglycidyl isocyanurate, when the laminated board is hot-pressed, the strength of the impact layer can be greatly improved, the mechanical performance is improved, the impact resistance is high, adhesiveness between the surface layer paper and the decorative paper is higher, and the laminated board has little possibility of cracking.

Description

technical field [0001] The invention relates to a method for manufacturing a high-strength thermosetting resin high-pressure laminate, belonging to the field of building materials.
