Problems solved by technology

The keel made of wood is easy to process and easy to use, but it is flammable and does not meet the fire safety requirements. At the same time, its strength is also weak; while the keel is made of steel Although the bone has the characteristics of non-combustibility and good strength, it is not easy to process and manufacture, and the production cost is too high. At the same time, its weight is relatively heavy, so it is not suitable for use as a ceiling and other purposes, and it is also inconvenient to install.

Embodiment 1

[0041] Embodiment 1, a non-combustible lightweight keel that can replace wood of the present invention, it includes the following components and parts by weight: cement 25, magnesium oxide 5, aluminum oxide 1.5, silicon dioxide 40, calcium oxide 21, Reinforcing fiber 2, vegetable fiber 15, admixture 0.008, and auxiliary agent 1; wherein, the admixture is moisture-proof liquid; the auxiliary agent is industrial alkali; the reinforcing fiber is glass fiber.

[0042] see figure 1 Shown, lightweight keel of the present invention is made by following steps;

[0043] Step a is the batching process 1. This process is to select cement, magnesia, aluminum oxide, silicon dioxide, calcium oxide, glass fiber, vegetable fiber, moisture-proof liquid, and industrial alkali as raw materials, and use the above formula in parts by weight weighing separately;

[0044] Step b is the initial mixing process 21, 22. The process 22 is to put the weighed cement, magnesia, aluminum oxide, silicon dio...

Embodiment 2

[0053] Embodiment two, see image 3 As shown, a non-combustible lightweight keel that can replace wood in the present invention is different from Embodiment 1 in that it is a strip 30 made by one-time extrusion molding, and the strip 30 has a frame The cross section is rectangular, and the strip 30 is provided with a through hole 31 along the middle of the cross section, and the shape of the through hole 31 is rectangular.

[0054] The keel 30 is more suitable as an aggregate for indoor suspended ceilings, and can also be used as an aggregate for making furniture.

Embodiment 3

[0055] Embodiment 3, a non-combustible lightweight keel that can replace wood of the present invention, it includes the following components and parts by weight: cement 28, magnesium oxide 30, aluminum oxide 0.5, silicon dioxide 37, calcium oxide 6, Reinforcing fiber 8, vegetable fiber 23, admixture 0.075, auxiliary agent 0.35; wherein, the admixture is a moisture-proof liquid; the auxiliary agent is baking soda; the reinforcing fiber is an organic fiber. The above raw materials can be obtained after the steps of batching 1, initial stirring, that is, dry material stirring 22 and mixture stirring 21, stirring 3, vacuum pumping 4, extrusion molding 5, steam curing 6, detection and storage 7, etc. lightweight keel.

Abstract

The invention discloses a non-combustible lightweight keel for substituting timber and its preparing process, which is produced from cement, magnesium oxide, alumina Al2O3, silicon dioxide, calcium oxide, fortifying fiber, plant fiber, additive and auxiliary agent through the steps of proportioning, mixing, vacuum evacuating, extrusion molding, vapor curing and inspecting.

Description

technical field [0001] The invention relates to a building material, in particular to a non-combustible lightweight keel that can replace wood and a manufacturing method thereof. Background technique [0002] The keel is a commonly used building material. It is mostly used as an aggregate for the decoration of buildings. For example, the roofs of many family rooms or offices are usually made of suspended ceilings. The suspended ceiling is made of keels. As the skeleton in the ceiling, the ceiling can be fixed on the top of the house only when the keel is used; the keel is also used more often as the skeleton of the partition wall of the building. With the rapid development of my country's national economy, people's living standards A large number of high-rise buildings have appeared, and these buildings are generally frame-type. One advantage of this frame-type structure is that it can be convenient to separate different indoor spaces according to needs. When separating these ...
