Abstract

The invention discloses a processing technology for producing a refractory board from modified kraft paper, which specifically comprises the following steps: 1) production of modified kraft paper and 2) dipping and hot-pressing treatment of the modified kraft paper. The present invention improves the refractoriness and abrasion resistance of the existing kraft paper by modifying it, then adopts the treatment method of sodium borohydride + silanization to treat the surface of the modified kraft paper, and then assists the method of vacuum impregnation treatment by ultrasonic waves The fiber structure of the modified kraft paper is covered by melamine glue and phenolic glue to a greater extent, so that the fire-resistant board has better fire resistance, abrasion resistance and water resistance, thereby improving the service life of the fire-resistant board.

Description

Technical field [0001] The present invention belongs to the technical field of building materials, and more particularly to a process of processing refractory panels in a modified kraft paper. Background technique [0002] With the development of society, people's safety awareness is gradually improved. For people of building materials, it is gradually attaches importance, especially fire protection, fire-resistant. The fire-resistant plate is also known as fire boards, is surface decoration with refractory building materials, rich surface color, ripples, and special logistics performance, widely used in interior decoration, furniture, cabinets, laboratory countertops, exterior walls and other fields. [0003] Refractory plates are usually titanium powder, kraft paper passes through melamine and phenolic resin, and then high-temperature high pressure molding. With the rapid development of all walks of life, new materials are also constantly developing. As the indispensable new ma...
