Problems solved by technology

[0003] However, in the existing lightweight wall panels, there is a problem of poor fire and heat insulation effect
When a fire occurs, it is difficult to prevent the spread of the fire in time, and to isolate the heat released by the combustion, so as to prevent major accidents; and the overall strength of the existing lightweight wallboards is low, often resulting in excessive external force or impact. It is bent, broken or cracked, which will affect the normal service life

Embodiment 1

[0026] A fire-proof and heat-insulating lightweight wallboard, comprising an integral layer and an embedded layer, the embedded layer is evenly arranged in the integral layer, the embedded layer is a modified grid cloth, and the length, width and thickness are respectively 50 mm , 50 mm and 2.5 mm;

[0027] The modified mesh cloth is produced by the following steps: first cut the mesh cloth to the required size, then repeatedly polish both sides of the mesh cloth with sandpaper until fluffy short fibers appear, and then place it in a 75-degree Soak in styrene-butadiene latex for 30 minutes, then take it out and use a steel needle to evenly pierce the pinholes, and after drying and cooling, to obtain a modified mesh cloth with a gel-like interlayer attached to the surface;

[0028] The raw materials in the overall layer are respectively 30% Portland cement, 15% cinder, 15% slag, 15% sawdust, 7.5% borax, 7.5% glass fiber, 5% Sodium rosinate and 5% modified flame retardant addit...

Embodiment 2

[0038] A fire-proof and heat-insulating lightweight wallboard, the difference from Example 1 is that the modified flame-retardant additive is prepared by the following steps: first, 2-ethyl ethanol, propylene alcohol and phosphorus oxychloride Add together in the reaction kettle for mixing, and the temperature in the reaction kettle is controlled at 5 degrees. After stirring for 5 minutes, it is initially heated to 20 degrees and kept for 30 minutes, and then raised to 40 degrees for the second time and kept for 30 minutes. Add liquid bromine to the reaction kettle and keep it for 15 minutes, and finally pass through ammonia water and wash with water, distill and cool to obtain a modified flame retardant additive;

[0039] The raw materials in the modified flame retardant auxiliary agent are respectively 20% of 2-ethyl ethanol, 20% of propylene alcohol, 45% of phosphorus oxychloride and 15% of liquid bromine by weight percentage.

Embodiment 3

[0042] A fire-proof and heat-insulating lightweight wallboard, the difference from Example 1 is that the modified flame-retardant additive is prepared by the following steps: first, 2-ethyl ethanol, propylene alcohol and phosphorus oxychloride Add them together to the reaction kettle for mixing, and the temperature in the reaction kettle is controlled at 5 degrees. After stirring for 5 minutes, it is initially heated to 20 degrees and kept for 30 minutes, and then raised to 40 degrees for the second time and kept for 30 minutes. After that, the When the temperature of the reaction kettle is lowered to 10 degrees, sodium phenate is introduced, and kept at 50 degrees for 30 minutes, and finally ammonia water is introduced and washed with water, distilled and cooled to obtain a modified flame retardant additive;

[0043] The raw materials in the modified flame retardant auxiliary agent are respectively 20% of 2-ethyl ethanol, 20% of propylene alcohol, 45% of phosphorus oxychloride...

Abstract

The invention discloses a fire-proof and heat-insulating light-weight wallboard and its production process. , width and thickness are 50 millimeters, 50 millimeters and 2.5 millimeters respectively; Described modified mesh cloth is produced by following steps: first mesh cloth is cut to the required size, and its both sides are all repeatedly polished with sandpaper, Until fluff-like short fibers appear, then soak them in styrene-butadiene latex at 75 degrees for 30 minutes, then take them out and use steel needles to evenly pierce the pinholes, and dry and cool to obtain gel-like fibers attached to the surface. Modified mesh cloth for the interlayer; the light-weight wallboard in the present invention has easy-to-obtain raw materials and low cost, not only can make full use of cinders, slag and sawdust, greatly improves energy conservation and environmental protection, but also has excellent fire protection The heat insulation effect is suitable for large-scale promotion and use.

Description

technical field [0001] The invention relates to the technical field of lightweight wall panels, in particular to a fireproof and heat-insulating lightweight wall panel and a production process thereof. Background technique [0002] Lightweight wallboard is an abbreviation for a class of lightweight partition wall slats for construction. It refers to the use of lightweight materials or light components. Both sides are equipped with tenon, tenon and joint grooves. It is often used in industrial and civil buildings. Prefabricated battens for non-load-bearing internal partition walls. Lightweight wall panels can be divided into four categories: hollow slats, solid slats, composite slats and energy-saving slats according to the type of structure. [0003] However, in the existing lightweight wallboards, there is a problem of poor fireproof and heat insulation effects. When a fire occurs, it is difficult to prevent the spread of the fire in time, and to isolate the heat released...
