Abstract
The synthetic foam building block is made up of compound inorganic adhesive, flyash, light magnesium oxide, diluting liquid, solidifying agent and foaming agent through mixing, reaction, natural solidification for shaping and demoulding, and features high-temp and low-temp resistance, low water absorption, high strength and better thermal conductivity.
Description
The present invention is a kind of synthetic foam building block and product, and this product can be widely used on the various high-rises.
At present, both at home and abroad existing various light building blocks are with adding such as flyash, coal gangue and light magnesium oxide, lime, cement, gypsum fully or do not add chemical feedstocks, method such as repressed, as to fire, steam is produced, great majority are to introduce external bulky equipment, big, the complex manufacturing of its investment, the material cost height.Waste energy, the product pull-out capacity is little, water regain, water content height, easily efflorescence.
The objective of the invention is to provide the production formula and the product of the inorganic synthetic foam building block of a kind of novel powdered coal ash in order to overcome the deficiencies in the prior art, need not to steam pressure heating installation and electric energy thereof, heat energy, utilize power plant's waste material flyash and an amount of concretionary novel product of chemical additive building-up reactions natural foaming thereof.
The object of the present invention is achieved like this:
1, the prescription of this synthetic foam building block is made of composite inorganic glue 20～30%, flyash 60～70%, light magnesium oxide 25～30%, diluent 30～40%, solidifying agent 3～5%, 6～8% of whipping agents.
Wherein: diluent is made by hydrochloric acid, magnesium chloride.
Solidifying agent is made by three ethanol, alum, ethylene glycol.
Whipping agent is become by trolamine, hydrogen peroxide, third copper.
2, at first based on composite inorganic glue, adding screening back fineness is after 70～80 purpose flyash and light magnesium oxide, diluent, solidifying agent, whipping agent thoroughly stir, with the raw material that stirs pack into natural foaming and curing in the mould, after 3 hours foaming and solidifying, cut, react curing molding tread flaking in 5 hours once more, natural curing was finished product in 20 days.
The present invention is main raw material and in addition an amount of chemical additive with flyash, composite inorganic glue.Chemical reaction through the short period of time is plastic caking, and this product has resistance to compression, anti-folding, tensile strength height.Advantages such as water ratio, low, the anti-low temperature of water-intake rate, high temperature resistant, drying and watering cycle, good heat conductivity are the novel high-rise light building materials of a kind of ideal.
Embodiment:
Synthetic foam building block and product are that fineness is that 70～80 purpose flyash 60～70% are main raw material with screening afterwards with composite inorganic glue 20～30%, add light magnesium oxide 25～30%, diluent 30～40%, solidifying agent 3～5%, after whipping agent 6～8% thoroughly stirs, the raw material that stirs is packed in the mould, natural foaming and curing, after foaming in 3 hours and solidifying, cut, react curing molding tread flaking in 5 hours once more, natural curing was finished product in 20 days, result after this product test is: ultimate compression strength 2.4MPa, water ratio 2.2%, water-intake rate 30%, frost resistance is qualified, weight loss 2.7%, loss of strength 7.6%, drying shrinkage 0,0.03 kilocalorie/hmc of thermal conductivity.Above technical indicator meets GB11968-89 standard fully, and wherein: drying shrinkage, moisture, water-intake rate, frost resistance are better than national standard.Following table is this product and prior art index contrast table:
The production technique of composite flyash foamed building block is simple, need not huge mechanical means, invests little, instant effect, succeeding in developing of this product for China's building materials industry provides a kind of novel material resource, saved the soil, turning waste into wealth, is the ideal architecture material that high-rise is used.
