China has a large amount of newly constructed house every year, only within 2013, just has 20.1 hundred million square metres of newly constructed houses, and annual newly constructed house area is also in increase.Along with the needs of the construction of national development " resource-conserving, environmentally friendly " society, building energy conservation is subject to increasing attention.Present stage building energy conservation enforcement, mainly reduce the energy loss of refrigeration and heating in house use procedure, this not only relates to the improvement of heating refrigeration equipment, the more important thing is and strengthens house building enclosure energy-efficient treatment, reduces Discussion on architecture thermal convection thus realizes building energy conservation.No matter the energy-efficient treatment to the building enclosure that newly finishes a house, or the reducing energy consumption to old house building enclosure, all need to use a large amount of heat insulating wall materials.Wherein, cement based foamed products, as cement foaming insulation board, aerated blocks etc., has the advantages such as cost is low, performance good, environment friendly and pollution-free, is widely used gradually.
In the production of China's cement insulation board, remain in some technological deficiencies, the sedimentation wherein comparatively seriously occurred in cement foaming insulation board production process, mould situation of collapsing, had a strong impact on the quality of production efficiency and product; The problem that the not enough water-intake rate caused of the compactness of cement foaming insulation board air vent wall is higher in addition, easily causes product heat-insulating property to decline and weather resistance declines.Cause sedimentation, mould phenomenon of collapsing occur reason be: add in the cement slurry good to mixing whipping agent formed porous foaming idiosome after, because suds-stabilizing agent surely steeps limited time, and cement setting formation intensity needs the regular hour, to support its deadweight, the even overall sedimentation of subsiding of local will be there is, collapse mould in the foaming idiosome undercapacity of porous.
In addition, when producing at different ambient temperatures, the surface hardening time of cement foaming insulation board and envrionment temperature are obvious negative correlation, and when winter environment temperature is not less than 5 DEG C, its surface hardening time is not less than 135min; And when summer environment temperature is not less than 25 DEG C, its surface hardening time is not less than 75min.When only using ammonium stearate as suds-stabilizing agent, the foaming idiosome surface hardening time is not better higher than foam stabilizing effect during 60min, and mould rate of collapsing is very low; There is certain sedimentation phenomenon and along with the increase of mould rate of collapsing in foaming idiosome surface hardening time 60 ~ 90min; The foaming idiosome surface hardening time, mould rate of collapsing was higher when more than 120min.
For solving the problem, the steady bubble time of suds-stabilizing agent need be extended and accelerate the rate of setting of cement.Comparatively general way uses the rapid hardening cement Substitute For Partials such as aluminosulfate cement or whole silicate cement at present, thus shorten the time of coagulation of gelling material.But do like this along with series of side effects: 1) rapid hardening cement longterm strength causes product strength to decline lower than ordinary Portland cement; 2) rapid hardening cement aquation condensation post-shrinkage ratio is comparatively large, easily causes the decline of product compactness thus causes ftractureing and the increase of water-intake rate; 3) when using part or all of rapid hardening cement to substitute ordinary Portland cement, the Costco Wholesale of production is added, the complexity of production technique also increased.
