Abstract

The invention relates to a method for manufacturing a thermosetting resin high-pressure laminated board. The method comprises the following steps: respectively dipping surface paper and decorative paper in a modified melamine resin at the temperature of 70-80 DEG C for 2-3 hours; laminating the dipped surface paper and decorative paper with bottom paper dipped by using a phenolic resin, and performing hot-pressing under the pressure of 8-10MPa and the temperature of 140-160 DEG C for 45-60 minutes. According to the thermosetting resin high-pressure laminated board disclosed by the invention, the surface paper is dipped by adopting the modified melamine resin, and a dense protective film is formed after hot pressing and is tightly combined with the bottom paper, so that the laminated board is high-temperature-resistant and water vapor-resistant and is difficult to bulge and crack.

Description

technical field [0001] The invention relates to a method for manufacturing a thermosetting resin high-pressure laminate, which belongs to the field of construction. Background technique [0002] Thermosetting resin high-pressure laminated board is a building decoration material formed by high-pressure hot pressing after laminating the surface paper impregnated with amino resin, decorative paper, and the bottom paper impregnated with phenolic resin. [0003] If the thermosetting resin high-pressure laminated board in the prior art is used under the condition of high temperature and high water vapor content, problems such as swelling and cracking of the surface layer of the laminated board are easily caused. Contents of the invention [0004] The purpose of the present invention is to provide a method for manufacturing a thermosetting resin high-pressure laminate to solve the problems in the prior art. [0005] Technical scheme of the present invention is: [0006] A meth...
