Problems solved by technology

The magnesium oxychloride sheet produced in the traditional way has the advantages of high strength, good elasticity, and good fire resistance. However, the magnesium oxychloride sheet has the fatal disadvantage of being easy to return halogen due to the high content of magnesium chloride, so it cannot be used in many building materials fields.
The traditional formula is used for mass production of plates. After the solution meets iron, the surface of the iron machine is prone to rust, which is not conducive to mass production of the machine.

Embodiment 1

[0027] The raw material weight ratio of the environment-friendly inorganic composite non-combustible board provided by the present invention is: 40 parts of light-burned magnesium oxide; 40 parts of magnesium sulfate solution, mix the two, and then add 10 parts of fillers, which are fly ash and talcum powder , a mixture of aluminate cement (the specific gravity is 5:2:3), 40 parts of fibrous fillers are fibrous filaments such as bamboo silk and wood wool that are processed and discarded; 3 parts of water-resistant additives (using paraffin wax ); 3 parts of toughening agent (using water-soluble resin material); 5 parts of modifying agent (foaming material Baolilong ball), the above formula is produced by the above-mentioned mechanical manufacturing method, and it is 18mm finished product in 7 days of natural maintenance. The dry flexural strength is 15Mpa; the data obtained after immersing in water at 25°C for 30 hours and placing the specimen in an oven at 100°C-105°C for 2 ho...

Embodiment 2

[0029] 35 parts of lightly burned magnesia; 30 parts of magnesium sulfate solution; 10 parts of filler (the proportion of fly ash, talcum powder, and aluminate cement is 5:2:3); 45 parts of fibrous filler; water-resistant additive 3 parts (using phosphoric acid); 3 parts of toughening agent; 5 parts of modifier. The above formula is produced according to the above-mentioned mechanical manufacturing method. After 6 days of curing, the dry bending strength of the 10mm finished product is 18Mpa; the moisture absorption deformation rate is 0.21%; it is placed in a 95-100% humidity box at 25°C for 30 days. Small drops of water appeared.

Embodiment 3

[0031] 40 parts of lightly burned magnesia; 35 parts of magnesium sulfate solution; 15 parts of filler (the specific gravity of fly ash, talcum powder, and aluminate cement is 7:3:5); 25 parts of fibrous filler; water-resistant additive 2 parts (using phosphate); 5 parts of toughening agent; 3 parts of modifier. The above formula is produced according to the above mechanical manufacturing method. After 6 days of curing, the dry bending strength of the 18mm finished product is 14Mpa; the moisture absorption deformation rate is 0.11%; it is placed in a 95-100% humidity box at 25°C for 30 days. Small drops of water appeared.

Abstract

The present invention relates to a new environment-protecting inorganic composite flame-resisting plate and its production method, belonging to the field of artificial plate material and its production technology. Said invention adopts a laminated structure, including face layer, inner core layer and bottom layer. It is characterized by that the proportional formula adopted by face layer and bottom layer is formed from (high concentration) magnesium sulfate solution, light calcined magnesia, filling agent, water-proofing additive and toughening agent. The formula of its inner core layer is characterized by that on the basis of above-mentioned face layer and bottom layer formula a fibrous filling agent and a modifying agent are added. Said invention also provides the concrete steps of its production method.

Description

technical field [0001] The patent of the invention relates to wood-based panel material and its manufacturing method, which is a new type of environment-friendly inorganic composite non-combustible panel. Background technique [0002] At present, the boards on the market can be divided into two categories according to their materials: solid wood boards and wood-based boards. Except for special parts that use solid wood boards, generally the boards we use are artificially processed wood-based boards. According to the classification of molding, it can be divided into: solid board, plywood, fiberboard, decorative panel, fireproof board and so on. [0003] Due to the increasing shortage of domestic timber resources and the implementation of the national sustainable development strategy, the market development of solid wood panels and wood-based panels processed from wood will be limited; another type of wood-based panels that use crop stems as raw materials will There are defi...
