Embodiment 1

[0007] Composition ratio

[0008]

[0009] Among them, the magnesium-aluminum composite cementitious material is made by stirring and mixing uniformly 40 kg of light-burned magnesium oxide (Mg0 > 80%), 30 kg of brine, 3 kg of aluminate cement, and 5 kg of talcum powder.

[0010] Mix the magnesium-aluminum composite cementitious material with hollow floating beads, expanded vermiculite, rice straw, fly ash, and silica fume evenly, then add sodium dihydrogen phosphate and boric acid to stir and mix, add and adjust to formable materials, pour into molding, and maintain In 7 days, the present invention was obtained. Its performance indicators are shown in Table 1.

Embodiment 2

[0012] Composition ratio

[0013]

[0014] Among them, the magnesium-aluminum composite cementitious material is prepared by stirring and mixing uniformly 45 kg of light-burned magnesium oxide (Mgo>80%), 32 kg of brine, 2 kg of aluminate cement, and 1 kg of talcum powder.

[0015] After the magnesium-aluminum composite gelling material is uniformly mixed with expanded vermiculite, wheat straw, fly ash, and water glass, phosphoric acid and boric acid are added to stir and mix, water is added to adjust to become a material, casting is formed, and the invention is obtained by curing for 10 days. Its performance indicators are shown in Table 1.

Embodiment 3

[0017] Group ratio

[0018]

[0019]

[0020] Among them, the magnesium-aluminum composite cementitious material is prepared by stirring and mixing uniformly 42 kg of light-burned magnesium oxide (Mg0>80%), 30 kg of brine, 5 kg of aluminate cement, and 2 kg of talcum powder.

[0021] Mix the magnesium-aluminum composite cementitious material with hollow floating beads, expanded vermiculite, rice straw, fly ash, and alumina evenly, then add aluminum phosphate and 8291 unsaturated polyester resin to mix, add water to adjust to a moldable material, and cast to form , the present invention was obtained after 8 days of maintenance.

Abstract

The invention provides a composite environment-friendly fireproof board which comprises the following components in parts by weight: 50-80 parts of magnesium-aluminum composite gel material, 0-20 parts of hollow floating beads, 2-20 parts of expanded vermiculite, 8-32 parts of at least one of crop straws, saw wood dust and grain bran meal, 5-20 parts of coal dust, 2-8 parts of flame-proofing agent and 1-10 parts of compound modifier. The wallboard has the advantages of excellent fireproof and sound-isolating performances, high strength, no halogen return, no frost return and waterproofness and can be sawed and nailed, industrial and agricultural wastes are comprehensively utilized, and no three wastes are generated in production. The board is mainly used for non load bearing partitions.

Description

technical field [0001] The invention relates to a building board, in particular to a composite environment-friendly fireproof board. Background technique [0002] At present, various wall panels have been widely used as building partition walls. Chinese patent CN1173475 discloses a lightweight partition wall panel whose components are composed of fly ash, magnesium oxide, magnesium chloride brine, ordinary cement and expanded foaming liquid. , it takes 4 to 24 hours to cure at room temperature, and the curing time is long. Two layers of medium-alkali glass mesh cloth or steel wire mesh cloth need to be embedded in the middle of the partition wall to meet the strength requirements. The board is reinforced with PVC plastic pipe or steel pipe, which is costly. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a composite environment-friendly fireproof board with excellent fire resistance, sound insulati...
