Embodiment 1

[0033] A method for manufacturing light-burned dolomite foamed lightweight partition boards, comprising the following steps in sequence:

[0034] (1) Raw material measurement: lightly burned dolomite powder, industrial waste residue, blending agent solution, thickener, light aggregate, chopped fiber, gas conditioner, water-resistant additive, and water reducing agent according to the requirements of embodiment 2-9 Mixing ratio, measured separately;

[0035] (2) mixing and stirring: the measured raw materials are mixed evenly, and stirred to make a lightly burned dolomite mixture;

[0036] (3) Pouring molding: inject the lightly burned dolomite mixture into the mold to make a solid or hollow cross-sectional shape. During the pouring process, the glass fiber mesh cloth needs to be evenly spread on the upper and lower surfaces of the 3-20mm slurry middle;

[0037] (4) Natural maintenance: After the light-burned dolomite foamed lightweight partition board is cured, it is demould...

Embodiment 2-17

[0038] Embodiment 2-17 list is as follows:

[0039] Use the preparation method of Example 1 in the embodiment 2-17, prepare light-burned dolomite foamed lightweight partition board (hollow) according to the formula of table 1 and table 2, light-burned dolomite foamed lightweight partition board specification It is 3600mm×600mm×90mm.

Abstract

The invention relates to a light-burned dolomite foam light partition board, which comprises the following components in part by weight: 20 to 55 parts of light-burned dolomite powder, 30 to 85 parts of conditioner solution, 0.1 to 5 parts of chopped fibers, 0.01 to 8 parts of gas regulator, 0.01 to 8 parts of water-resistant admixture, 1 to 60 parts of industrial waste residues, 1 to 30 parts of thickener, 1 to 35 parts of lightweight aggregate, 1 to 16 layers of glass fiber mesh fabrics and 0.1 to 1 part of water reducing agent. The foam light partition board has the advantages of no steam curing or autoclave curing, normal temperature quick reaction and curing, high strength and water resistance, no moisture absorption or halogenation, no scumming, freezing resistance, sound insulation, thermal insulation, heat preservation, flame retardance, utilization of a large number of industrial waste residues and agricultural wastes, resource and energy saving, no emission of waste gas, waste water and waste residues (three wastes), and the like, has low production cost and good social and economic benefits, and is mainly used for a non load bearing partition.

Description

technical field [0001] The invention relates to a partition wall board, in particular to a light-burned dolomite foamed lightweight partition wall board. Background technique [0002] The reform of wall materials is an important part of protecting land resources, saving energy, comprehensively utilizing resources, and improving the environment. Promoting the use of new wall materials is one of the important ways to develop a low-carbon economy, realize building energy conservation, and achieve sustainable social development. In modern buildings, especially high-rise buildings with frame structures, most of the interior walls use foamed lightweight profiles, such as foamed concrete lightweight wall materials processed from ordinary cement, fly ash and foaming agents. Its strength and rigidity are poor. In order to improve the strength of lightweight interior partition wall materials, some normal temperature curing foam wall panels with magnesium oxychloride cement as the cem...
