Embodiment 1

[0010] The substrate board 3 is a multilayer board of 1220mm×2440mm×18mm, the composite laminate 1 is a magnesia glass fiber board with a thickness of 3.5mm, and the adhesive 2 is a phenolic resin glue: 0.5 kg, flour: 0.15 kg, After blending with each other, apply it evenly on the multi-layer board with a glue spreader, spread the magnesium oxide glass fiber board, pre-press for 18 minutes, and then put it into a hot press for hot pressing. The pressure is: 8 kg / cm2, hot pressing temperature The temperature is: 140°C, the hot pressing time is: 30 minutes, and then taken out, after sanding, shaping, and packaging, a fireproof and waterproof composite board with a size of 1220mm×2440mm×20mm is completed.

Embodiment 2

[0012] Substrate 3 is made of multi-layer plywood of 1220mm×2440mm×15mm, composite laminate 1 is made of magnesia glass fiber board with a thickness of 3mm, the temperature is normal temperature, adhesive 2 is made of styrofoam: 1 kg, pressing pressure: 3 kg / Cm2, pressing time: 40 minutes, after taking it out, sanding, shaping, and packaging to form a fireproof and waterproof composite board of 1220mm×2440mm×18mm.

Abstract

The fireproof and waterproof composite board with magnesia layer consists of one glass fiber reinforced magnesia board and one woody base board combined together with resin glue, foamed glue, universal glue or powerful glue, and the woody base board may be veneer, multilayer board, shaving board or artificial board. The fireproof and waterproof composite board is produced through painting adhesive between the glass fiber reinforced magnesia board and the woody base board and pressing to combine. It has simple structure, simple production process, high fireproof and waterproof performance, high strength and environment friendship.

Description

technical field [0001] The invention relates to a fireproof and waterproof composite board with a magnesium oxide board layer. Background technique [0002] At present, there are many types of wood-based panels and plywood with different performances, but because this kind of boards are all made of wood materials, they often have the disadvantages of poor fireproof and waterproof performance. In order to improve their fireproof and waterproof performance, various manufacturers have gradually introduced some Composite panels with fireproof and waterproof properties, but their performance is not ideal, at present, there is no very ideal solution. Contents of the invention [0003] In order to solve the problem of poor fireproof and waterproof performance of wood composite boards, the present invention provides a fireproof and waterproof composite board. Although the structure and process of the composite board are relatively simple, its fireproof and waterproof performance i...
