Problems solved by technology

The existing partition boards have the following disadvantages: 1. Poor flexural strength, which is only 0.75 to 1.2 times the weight of the partition board body; 2. Easy to distort and deform; 4. After the partition board is installed, a layer of oxide film is formed on the surface of the board. After painting, the paint layer is partially yellowed and easy to fall off; 5. The expansion rate is large. After installation, the distance between the partition board and the partition board prone to cracks

Embodiment 1

[0015] Present embodiment is to be made by the raw material of following percentage by weight:

[0016] Magnesium oxide 45%, magnesium chloride 30%, dry stone powder 5%, fly ash 4%, talcum powder 2.5%, high alumina cement 1.5%, ferrous sulfate 1%, trisodium phosphate 1%, phosphoric acid solution 0.2%, sawdust 9.8 %.

[0017] The preparation method is as follows: prepare the raw materials according to the above formula, add water, roll and stir, pour into the mold cavity for one-time molding, after curing for 72 hours, soak the board in clean water for 48 hours, take it out, stack it, dry it, and store it after passing the inspection .

Embodiment 2

[0019] Present embodiment is to be made by the chemical raw material of following percentage by weight:

[0020] Magnesium oxide 43%, magnesium chloride 32%, dry stone powder 6%, fly ash 3%, talcum powder 3%, high alumina cement 1%, ferrous sulfate 1%, trisodium phosphate 1%, phosphoric acid solution 0.2%, sawdust 9.8 %.

[0021] The preparation method of this embodiment is the same as that of Example 1.

Embodiment 3

[0023] Present embodiment is to be made by the chemical raw material of following percentage by weight:

[0024] Magnesium oxide 40%, magnesium chloride 33%, dry stone powder 5%, fly ash 3%, talcum powder 3%, high alumina cement 2%, ferrous sulfate 1%, trisodium phosphate 1%, phosphoric acid solution 0.2%, sawdust 11.8 %.

[0025] The preparation method of this embodiment is the same as that of Example 1.

Abstract

The invention is about a sort of lightweight partition wall board. It is made from magnesium oxide, magnesium chloride, dry rock powder, flyash, French chalk, high alumina cement, ferrous sulfate, tertiary sodum phosphate, phosphoric acid solution and sawdust. The lightweight partition wall board has the following advantage: the fist, it can save energy, reduce cost and have no pollution. The second, the board has fine intensity, good water resistance and resistance to aging. The third, it has small shrinkage, get over the problem that appear when the boards join. The fourth, the partition wall board no longer distort for using inorganic material and controlling the quality of material. Lastly, it has good shock resistance, waterproof, fire resistance, soundproofing and it get over the partition wall board to be yellow.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a lightweight partition wall board. Background technique [0002] At present, although there are various kinds of partition boards used on the market, there are also many shortcomings. The existing partition boards have the following disadvantages: 1. Poor flexural strength, which is only 0.75 to 1.2 times the weight of the partition board body; 2. Easy to distort and deform; 4. After the partition board is installed, a layer of oxide film is formed on the surface of the board. After painting, the paint layer is partially yellowed and easy to fall off; 5. The expansion rate is large. After installation, the distance between the partition board and the partition board Cracks are prone to appear. Contents of the invention [0003] The object of the present invention is to overcome the deficiency of the background technology, and provide a kind of light-weight partiti...
