Embodiment 1

[0012] A cement foam light board is formed by adding cement foaming agent to the cement slurry and then pouring it into a mold to solidify. The cement slurry includes the following components in parts by mass: 25 parts of acid cement, 10 parts of sodium polyacrylate , 10 parts of calcium chloride, 5 parts of sodium bicarbonate, 5 parts of magnesium oxide, 5 parts of sodium dodecylbenzenesulfonate, 3 parts of disodium edetate, 10 parts of quartz sand, 5 parts of sodium pyrophosphate; The acid cement of the present embodiment is a mixture of Portland cement and sulphoaluminate cement;

[0013] The cement foaming agent comprises the following components by mass: 25 parts of cement composite foaming agent paste, 10 parts of hydrogen peroxide, 1 part of polyether modified silicone oil, and 10 parts of water; The paste, hydrogen peroxide, polyether modified silicone oil and water are added into a high-speed mixer and stirred to obtain a cement foaming agent.

Embodiment 2

[0015] A cement foam light board is formed by adding cement foaming agent to cement slurry, stirring it, pouring it into a mold and solidifying it. The cement slurry includes the following components by mass: 35 parts of acid cement, 15 parts of sodium polyacrylate , 25 parts of calcium chloride, 10 parts of sodium bicarbonate, 15 parts of magnesium oxide, 8 parts of sodium dodecylbenzenesulfonate, 5 parts of disodium edetate, 15 parts of quartz sand, and 9 parts of sodium pyrophosphate; The acid cement of the present embodiment is sulphoaluminate cement;

[0016] The cement foaming agent comprises the following components by mass: 80 parts of cement composite foaming agent paste, 35 parts of hydrogen peroxide, 5 parts of polyether modified silicone oil, and 45 parts of water; The paste, hydrogen peroxide, polyether modified silicone oil and water are added into a high-speed mixer and stirred to obtain a cement foaming agent.

Embodiment 3

[0018] A cement foam light board is formed by adding cement foaming agent to the cement slurry and then pouring it into a mold to solidify. The cement slurry includes the following components by mass: 25 parts of acid cement, 10 parts of sodium polyacrylate , 10 parts of calcium chloride, 5 parts of sodium bicarbonate, 5 parts of magnesium oxide, 5 parts of sodium dodecylbenzenesulfonate, 3 parts of disodium edetate, 10 parts of quartz sand, 5 parts of sodium pyrophosphate; The acid cement of the present embodiment is Portland cement;

[0019] The cement foaming agent comprises the following components by mass: 25 parts of cement composite foaming agent paste, 10 parts of hydrogen peroxide, 1 part of polyether modified silicone oil, and 20 parts of water; The paste, hydrogen peroxide, polyether modified silicone oil and water are added into a high-speed mixer and stirred to obtain a cement foaming agent.

[0020] Since the cement slurry is made of acid cement, sodium polyacry...

Abstract

The invention discloses a foamed light cement board, and belongs to the technical field of production of foamed cement boards. The foamed light cement board is formed by adding a cement foaming agentinto a cement slurry, stirring, pouring into a mould and curing, wherein the cement slurry comprises the following components in parts by mass: 25-35 parts of acid cement, 10-15 parts of sodium polyacrylate, 10-25 parts of calcium chloride, 5-10 parts of sodium hydrogen carbonate, 5-15 parts of magnesium oxide, 5-8 parts of sodium dodecyl benzenesulfonate, 3-5 parts of disodium ethylenediaminetetraacetate, 10-15 parts of quartz sand and 5-9 parts of sodium pyrophosphate; the cement foaming agent comprises the following components in parts by mass: 25-80 parts of a composite cement foaming agent paste, 10-35 parts of hydrogen peroxide, 1-5 parts of polyether-modified silicone oil and 10-45 parts of water. Compared with the prior art, the foamed light cement board has the advantage as follows: the problem that the conventional foamed cement board has a poor foaming capability can be solved.

Description

technical field [0001] The invention relates to the technical field of cement foam board manufacture, in particular to a cement foam lightweight board used for building exterior walls. Background technique [0002] Cement foam board is launched in response to the national "Interim Regulations on Fire Protection of Civil Building External Thermal Insulation System and External Wall Decoration". After the cement foaming agent is mixed with the cement slurry and poured into shape, it is the best product currently used in the fire barrier. At present, the foaming agents used in the manufacture of cement foam boards can be divided into three categories: chemical foaming agents, physical foaming agents and surfactants; Correspondingly, the foaming ability is poor, which directly increases the bearing capacity of the main project, and cannot meet the needs of customers pursuing lightweight and environmentally friendly products. Contents of the invention [0003] The technical p...
