Embodiment 1

[0033] The preparation method of the cement steel wire grid insulation board foamed by magnesia salt gel material, the method specifically includes the following steps:

[0034] (a) Preparation of foamed cement

[0035] 65 kg of magnesia salt cement, 3 kg of foam stabilizer and 5 kg of foaming agent, add water according to the water-cement ratio of 0.45, and stir to make foamed cement slurry. The foam stabilizer is silicone amide; the foaming agent is sodium lauryl sulfate.

[0036] The preparation method of the magnesia salt cement is as follows: 100-200 mesh MgO, 100-200 mesh MgSO 4 and H 2 O, the three are mixed according to the ratio of the amount of substances of 9:1:25, and then add the inducer, the addition of the inducer is MgO, MgSO 4 and H 2 O 1 wt% of the total mass of the three, stirring for more than 24 hours, drying, grinding, and passing through a 200-mesh sieve to obtain magnesia salt cement.

[0037] The preparation method of the inducer is as follows: ad...

Embodiment 2

[0043] The difference between this embodiment and embodiment 1 is:

[0044] The inducer is composed of A component and B component, and the preparation method of A component is as follows: 200-400 mesh talcum powder is added to the vinegar-acrylic emulsion, and the mass ratio of the talc powder to the vinegar-acrylic emulsion is 8:27, Stir, be heated to 60 ℃ and keep 4 hours, filter and dry; Join in the tannic acid aqueous solution in the obtained solid product, the massfraction of tannic acid in the tannic acid aqueous solution is 10wt%, the mass ratio of solid product and tannic acid aqueous solution The ratio is 1:30, heated to 100°C and kept for 5 hours, filtered, dried and pulverized, and passed through a 100-mesh sieve to obtain component A; the preparation method of component B is as follows: add 200-400-mesh fly ash to three In the ethanolamine aqueous solution, the mass fraction of the triethanolamine aqueous solution is 5wt%, the mass ratio of the fly ash to the trie...

Embodiment 3

[0047] The difference between this embodiment and embodiment 2 is:

[0048] (a) Preparation of foamed cement

[0049] Add 65 kg of magnesia salt cement, pretreated fly ash, 3 kg of foam stabilizer and 5 kg of foaming agent, add water according to the water-cement ratio of 0.45, and stir to make foamed cement slurry. The amount of fly ash after pretreatment is 10wt% of the mass of MgO used in the preparation of magnesia salt cement.

[0050] The preparation method of the fly ash after the pretreatment is as follows: 200-400 mesh fly ash is added in the triethanolamine aqueous solution, the mass fraction of the triethanolamine aqueous solution is 3wt%, and the mass ratio of the fly ash and the triethanolamine aqueous solution is 1: 12. Stir, heat to 70°C and keep for 12 hours, filter and dry; add the obtained solid product to the silane coupling agent solution, the mass ratio of the solid product to the silane coupling agent solution is 1:16, silane coupling The mass fraction ...

Abstract

The invention discloses a cement steel mesh frame heat insulation board foamed from a magnesian salt gel material. The heat insulation board comprises a magnesium-based cement foamed board, a first steel wire screen piece and a second steel wire screen piece, the first steel wire screen piece and the second steel wire screen piece are arranged in the magnesium-based cement foamed board and are both of a screen-shaped structure composed of transverse steel wires and longitudinal steel wires, and the transverse steel wires and the longitudinal steel wires are perpendicular to each other. Inclined joint bar sets are arranged between the first steel wire screen piece and the second steel wire screen piece. The prepared cement steel mesh frame heat insulation board foamed from the magnesian salt gel material is simple in preparation line, capable of saving energy, environmentally friendly and capable of using waste, the required raw materials are low in price and easy to obtain, and production cost of the product is low.

Description

technical field [0001] The invention relates to the field of building material construction, in particular to a cement steel wire grid insulation board foamed with magnesia salt gel material. Background technique [0002] Inorganic cementitious materials with calcium salts as hydration products are widely used in civil engineering such as buildings, roads, bridges, tunnels, airports and dams. Common calcium cementitious materials include lime, gypsum, Portland cement, Aluminate cement and sulfoaluminate cement, calcareous cementitious materials have made significant contributions to the development of modern civil engineering. At present, most of the cement foam boards made of calcareous cementitious materials on the market use lime, gypsum and Portland cement as the main raw materials. This product has relatively high early strength, large later strength attenuation, poor thermal insulation performance, and low strength. Disadvantages such as poor durability. [0003] Sim...
