Problems solved by technology

Calcium silicate board (cement fiber pressure board) has the advantages of green, energy saving, environmental protection, fire prevention, waterproof and so on. In recent years, it has been used more and more in applications, but its decorative effect is poor. treatment to make it more decorative and colorful, such as surface-coated fireproof board, UV paint coating, PVC, wallpaper coating, etc. not ideal
People's attention began to turn to melamine impregnated paper, which is widely used. Because melamine resin and calcium silicate board cannot be directly bonded well, people apply epoxy resin, phenolic resin on the surface of calcium silicate board, or under melamine resin impregnated paper. Using phenolic resin impregnated paper transition to solve the problem of pressing and bonding, although the problem has been solved, but this is not only high cost, cumbersome process, low efficiency, large investment in equipment, and a series of shortcomings such as fire prevention, etc., which cannot reach Class A. Therefore, there is a need for the emergence of a new type of calcium silicate board hot-pressed veneer melamine impregnated paper

Abstract

The invention discloses a melamine impregnated paper for a hot-pressing veneering of a calcium silicate board and a manufacturing method thereof, the melamine impregnated paper comprises a calcium silicate substrate, the melamine impregnated paper is pasted on the calcium silicate substrate, and the melamine impregnated paper is modified by an organosilane coupling agent. The method specifically comprises the following steps: 1) preparing materials; 2) preparing a primary dipping mixed adhesive; 3) preparing a secondary dipping mixed adhesive; 4) carrying out primary impregnation; 5) carryingout secondary impregnation; 6) carrying out hot press molding. Compared with the prior art, the method has the advantages that according to the characteristics of the melamine resin, the organosilanecoupling agent is used for improving the crosslinking performance of the melamine resin to inorganic substances, so that the melamine impregnated paper and the calcium silicate board have good bondingcapacity, and the manufacturing method has the advantages of being rapid, efficient, low in cost, excellent in performance, capable of enabling the fireproof capacity of the product to reach the A level, formaldehyde-free, antibacterial and the like.

Description

technical field [0001] The invention relates to the field of decorative boards, in particular to the technical field of hot-pressed melamine-impregnated paper for oriented calcium silicate boards. Background technique [0002] With the progress of the times, the country's requirements for environmental protection and fire protection of decoration and decoration materials have increased. At the same time, the national industrial policy advocates and encourages prefabricated decoration, which requires the emergence and application of new materials. Calcium silicate board (cement fiber pressure board) has the advantages of green, energy saving, environmental protection, fire prevention, waterproof and so on. In recent years, it has been used more and more in applications, but its decorative effect is poor. treatment to make it more decorative and colorful, such as surface-coated fireproof board, UV paint coating, PVC, wallpaper coating, etc. not ideal.
