A kind of sintering stone material bee-hole twice-laid stuff
Technical field
The invention belongs to building material technical field, be specifically related to a kind of sintering stone material bee-hole twice-laid stuff.
Background technology
Grouan be a kind of magma condense below earth's surface formed volcanic rock, main component is feldspar and quartz.Because grouan is plutonite, often can be formed physically well develop, mineral grain that naked eyes can be distinguished, thus gain the name.Grouan is easy-weathering not, beautiful appearance, and appearance luster can keep more than a century, because its hardness is high, wear-resistant, except being used as senior building decorative engineering, hall floor, or the material of the first-selection of outdoor engraving.The natural formation of grouan needs through upper a century even more than one thousand years, because the mankind constantly exploit, the reserves of natural granite constantly reduce, and waste material and the granite powder of much grouan can be produced in the course of processing of grouan, the words that these waste materials and granite powder are not used, severe contamination will be produced, welding, restriction expanding economy.The method of traditional digestion granite powder adopts low temperature, mixed sticky technique makes twice-laid stuff, and the density of its product is large, reaches 2.5 tons/m, and heat transfer is fast, and needs to add chemical adhesive in making processes.
CN101357838A discloses one and utilizes granite powder waste material artificial compound board prepared, is made up of granite waste material.Formula comprises resin, solidifying agent, promotor, granite powder, gravel particle etc.This artificial composite plank, pattern is many, and length can be accomplished enough large, thus can be applied to various place.But employ inflammable or poisonous chemicals in the formula due to described artificial composite plank, know from experience and damage, and density is large, heavy weight to people, transport and installation are all inconvenient, are not easily incubated again, nor can reuse.Therefore, the structure of this composition board also needs to be further improved.
CN102786316A and CN103073328A all discloses a kind of generative foaming material utilizing granite powder to be raw material, this product stable physical property, lightweight, insulation, resistance to compression, anti-folding, can be used for construction wall or decoration of exterior wall, reach building loss of weight and energy-conservation target, and there is the performance of fire prevention, waterproof, sound insulation, can be used for fire-retardant material, body of wall barrier material, but in its raw material, still wrap virose chemical additive such as borated tool such as grade, and firing temperature reaches 1400 degree, cause the energy consumption of its making processes high, be unfavorable for energy-saving and emission-reduction.
