Abstract
The invention relates to the technical field of building materials, in particular to a lightweight foamed wall building material manufactured through recycling of solid waste and a manufacturing method. The foamed wall building material is a large block wall building material manufactured by applying a physical principle through instant foaming expansion, boiler heating is not needed, the wall building material is heated through magnesium chloride water, high-speed stirring is conducted, and the wall building material is formed through integral casting by pouring the materials into a large mold. The lightweight foamed wall building material manufactured through recycling of the solid waste and the manufacturing method have the advantages that specific investment is less, a boiler does not need to be installed, atmospheric pollution is reduced, the cost is low, the solid waste is utilized, the heat preservation effect is good, and the strength is higher than that of an aerated building block and reaches above 8.2 mpa; the waste is turned into treasure, and the silicate component in the solid waste is recycled.
Description
[technical field]
The present invention relates to building material technical field, is using the technology of construction wall packing material waste material as regeneration stopping composition, and solid waste regeneration utilizes the light-weight foam wall body building material and making method made specifically.
[background technology]
At present, high buildings and large mansions are built higher and higher, generally all adopt skeleton construction, need a large amount of partition wall building materials, and in order to alleviate the weight in building, the demand of light filling materials for wall body is increasing.Construction method is widely known by the people.Meanwhile, along with the continuous transformation in city, industry is greatly developed, and increasing building waste, industrial slag, cinder, slag the like waste are badly in need of solving.Containing gold in these wastes, silver, copper, iron, phosphorus comprises a large amount of flyash containing silicate, if arbitrarily wasted, not only contaminate environment, waste soil, has also wasted wherein favourable valuable composition.These waste materials above-mentioned can be used as the packing material of construction wall completely, and can be good at solving the prejudice that people cannot recycle for industrial residue.
Before this, had many people for developing in this respect and attempting, concrete aerated foam building block brick is in widespread use, but the investment of this manufacture method is large, boiler must be installed, steam, need to burn coal, waste resource, air is polluted, and intensity is poor, cannot nail be bored.
The patent that a castoff regenerative of China Patent No. to be 201210084892.9 be the applicant's earlier application utilizes, it discloses concrete grammar is under machine,massing or material distributing machine stir, add above-mentioned content light-burning magnesium powder, organosilicon, tertiary sodium phosphate, composite modifier, Aminosulfonic-acid high-efficiency water reducer, stir ten minutes, after making its uniform decomposition, batching is sent into full automatic brick making machine, the automatic compression moulding of hopper.
[summary of the invention]
The object of the invention is to produce a kind of lightweight building wall material of novelty, technique is advanced, need not install boiler, without steam, without maintenance, rapid shaping, and all adopt waste as stopping composition, through research, in industrial waste, building waste, especially flyash, containing a large amount of silicate component in slag, specifically has good modifying function.
To achieve these goals, design a kind of solid waste regeneration and utilize the foaming wall material of construction made, comprise rectangular tiles body and body of wall, the base material formula of this bulk one-piece casting and weight ratio as follows: building waste or solid industrial abandoned mine slag 65% ~ 75%, light-burning magnesium powder 8% ~ 10%, magnesium chloride, change water and be heated to 70 degree Celsius 3% ~ 6%, phosphoric acid 0.5% ~ 1%, oxalic acid 0.3% ~ 0.6%, inorganic compounding water repellent agent 0.3% ~ 0.5%, terra alba 2% ~ 4%, aluminium powder 0.3% ~ 0.5%, flyash 20% ~ 30%, wherein solid waste comprises building waste, industrial residue, flyash, slag and mud.
A kind ofly prepare the one-piece casting method that above-mentioned solid waste regeneration utilizes the foaming wall material of construction made, comprise rectangular tiles body and body of wall, one-piece construction casting method adopts the design of large mould, bulk is built, 70 degrees Celsius are warmed to by after the magnesium chloride water of above-mentioned content, the light-burning magnesium powder of above-mentioned content is added under strong stirring, phosphoric acid, oxalic acid, inorganic compounding water repellent agent, terra alba, aluminium powder, flyash, building waste or abandoned mine slag strong stirring made base material uniform decomposition after 6 minutes, reach instantaneous expansion, then pour in large-scale mould, after question response fully solidifies, building block and the large-sized sheet material of various desired shape can be cut into, base material hardness after shaping is more than 8.2mpa.
The present invention compared with the existing technology, its advantage is: structure is different, and technique is different, and technique effect is different, the wall body building material adopting this proportioning and method to make is higher than concrete aerated fly ash building block intensity, and heat-insulating property is also higher than concrete aerated fly ash building block, thermal conductivity can reach 0.27, greatly reduces the consumption of the energy, the minimizing of work personnel and the reduction of cost, because aerating need not be heated, without boiler, decrease the pollution of environment.
[embodiment]
The invention will be further described below, and the proportioning of this material and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment 1: every cube of base material formula per-cent of thorough piece of this entirety casting is as follows:
This entirety is cast building block and is provided with large mould, the magnesium chloride water of above-mentioned content is heated to 70 DEG C of degree, under the stirring of machine,massing, add the light-burning magnesium powder of above-mentioned content, phosphoric acid, oxalic acid, compound water repellent agent, terra alba, aluminium powder, flyash, building waste (or solid abandoned mine slag) strong stirring 6 minutes, make base material uniform decomposition, instantaneous expansion, then pour that to make it solidify physics voluntarily in pre-designed mould shaping into, shaping rear intensity is more than 8.2mpa, ultimate compression strength is high, thermal conductivity reaches 0.27, good heat insulating, lightweight, good endurance, long service life, easy processing, can cut, can certificate, can follow closely.
