Abstract
The invention discloses a novel composite building energy-saving building block and a manufacturing method thereof. The building block is characterized in that two vertically staggered rows of hole grooves are provided on a microporous lightweight concrete block, wherein each row of hole groove is separated into 2 holes by a rib. Insulation molded polystyrene boards and vermiculite boards are arranged in the holes with a staggered manner. The manufacturing method comprises the point that: a microporous lightweight concrete slurry is composed of common Portland cement, fast-hardening sulphoaluminate cement, vermiculite powder, spontaneous-combustion coal gangue powder, alkali-resistant chopped crack-resistant reinforcing fiber, a high-efficiency dispersing agent, and a foaming agent. The vermiculite boards are prepared through the steps that: vermiculite powder, phenolic resin, and silicone emulsion are blended; and the obtained material is subjected to extrusion molding in a mold. The building block provided by the invention has the advantages of good thermal insulation effect, high strength, and no fire hazard risk. The building block can be widely applied as building insulation and energy-saving building blocks.

Highrise building mostly is frame construction, and its body of wall is generally all filled with building block, and because there is the energy conservation standard requirement in country to building, body of wall must have function of heat insulation.The building block of present architectural use is generally sneaked into the moulding of insulation particle aggregate by bonding slurry and is made, and its defective is that intensity is low, and bad adhesion affects the follow-up face operation of plastering, and easily forms hollowing.Be that coefficient of thermal conductivity is high on the other hand, do not reach 65% energy conservation standard of national requirements.Some bodies of wall adopt outer wall pasting benzene plate method heat-insulation and heat-preservation, although improve heat insulation and preservation effect, the exterior wall large tracts of land is pasted the benzene plate, buries disaster hidden-trouble, is unfavorable for fire-fighting.
Three, summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide that a kind of heat insulation and preservation effect is good, intensity is high, do not stay NEW TYPE OF COMPOSITE building energy conservation building block of disaster hidden-trouble and preparation method thereof.
The building block of a kind of NEW TYPE OF COMPOSITE building energy conservation of the present invention, comprise the Lightweight porous concrete block, be characterized in: two round grooves vertically are crisscross arranged on described block, every round groove cuts off into two holes by rib, and one is blind hole, and one is uncovered hole, bolt rivet hole groove also is set in described uncovered hole, adiabatic molded polystyrene plate is set in described blind hole, in described uncovered hole, vermiculite board is set, the enterprise of described block closes end tongue-and-groove is set.
the preparation method of NEW TYPE OF COMPOSITE building energy conservation of the present invention building block is: at first prepare described vermiculite board standby, its preparation method is: vermiculite power 85%, phenolic resins 13%, the mould extrusion modling of packing into of organic silicon emulsion 2% mix, it is standby that adiabatic molded polystyrene plate is cut out in choosing, be ready to mould, and spray higher fatty acids water-based interleaving agent at die surface, conveniently to open mould, described higher fatty acids water-based interleaving agent is by higher fatty acids 10%, polyhydric alcohol polymer 0.05%, NaOH 3%, sorbester p17 0.95%, all the other form for water, described adiabatic molded polystyrene plate and described vermiculite board are arranged in mould, the described Lightweight porous concrete slip of cast in mould, fill it up with strike off after, insert maintenance in fog room, the water/binder ratio of described Lightweight porous concrete slip is between 0.4～0.6, it is according to the weight portion proportioning of following each material:
40 parts of Portland cements; 3 parts of quick hardening sulphoaluminate cements; 2 parts of vermiculite powers;
55 parts of spontaneous combustion gangue powders; 0.2 part of alkaline-resisting chopped cracking resistance fortifying fibre;
0.02 part of dispersant with high efficiency, described dispersant with high efficiency is comprised of calgon 50% and sodium phosphate trimer 50%;
Blowing agent, add 100 grams in every cubic metre of described Lightweight porous concrete slip, described blowing agent is comprised of lauryl sodium sulfate 55%, dodecyl sodium sulfate 28% and triethanolamine 17%, during use, water is pressed the dilution proportion of 1: 40, can join after dilution in foamed pot summer by dilution in 1: 50, uses air compressor machine, pressure is between 0.5～0.8MPa, and the foam of the compressed air stirring formation of described blowing agent bubble diameter 1mm is stand-by.
The present invention is owing to arranging two round grooves on block, filling with insulation material, and good heat-insulation effect, adiabatic molded polystyrene plate and vermiculite board are arranged alternately, and are provided with rib between groove, can improve on the one hand the intensity of body of wall, on the other hand good flame retardation effect.Bolt rivet hole groove is set in uncovered hole, can prevents that vermiculite board from coming off.The enterprise of block closes end tongue-and-groove is set, and is conducive to mortar bonding.
NEW TYPE OF COMPOSITE building energy conservation block performance of the present invention:
Over dry body unit weight 450～600 kilograms per cubic meter
Cubic compressive strength 〉=2.5MPa
Drying shrinkage value≤0.5mm/m
