Description
Technical field
The present invention relates to the materials for wall manufacturing process in the building field, be a kind of manufacture method of heat insulating wall material and the heat insulating wall material of production thereof, its product is mainly used in the civilian or Industrial buildings of heat preservation energy-saving.
Background technology
Current resource problem primarily is an energy problem, wherein 27.8% of the building energy consumption account total energy consumption.And the use energy consumption in the building energy consumption (contain and build energy consumption, use energy consumption) accounts for building energy consumption more than 80%.The heat preservation and insulation of building external envelope structure has determined the building energy conservation success or not, and the ratio maximum that exterior wall accounts in the peripheral structure of building, the thermosteresis that wall heat transfer causes accounts for about 50% of whole Building Heat loss.Therefore the heat-insulation and heat-preservation of body of wall is the important component part of building energy conservation.
The mode of body of wall heat-insulation and heat-preservation mainly is divided into: outer insulation, interior insulation and three kinds of patterns of self-heat conserving.Outer insulation pattern: external wall outer insulation (being commonly called as the coat of buildings) is by construction technologies such as powder, spray, subsides, and bag one deck insulating in the basic unit of wall outer side makes its resistance of heat transfer satisfy the energy-saving design standard outside; Phenomenons such as this pattern exists the displacement of external wall outer insulation surface layer, hollowing, ftracture, come off, and easily produce textural defect such as local mouldy, dewfall even Cheng Shuan; In addition, this pattern also exists energy-saving investment than problems such as big and poor durability, be about 70～90 yuan/square metre by the investment increase that insulating brought, and its working life is generally in 15～25 years.Interior insulation pattern: the heat-insulation and heat-preservation material that is adopted is identical with outer insulation pattern basically with construction technology, and different is that increase one deck insulating in the inboard basic unit of body of wall makes its resistance of heat transfer satisfy energy conservation standard outside; This pattern is subject to the influence of " cold bridge " phenomenon, and its insulating easily goes to pot when interior decoration, thereby influences the heat preservation and insulation of body of wall; And the inner heat insulation layer similarly exists problems such as poor durability and energy-saving investment be bigger.
Because there are many defectives in above-mentioned two kinds of patterns, for reaching the energy-saving design standard and improving its weather resistance and save investment, external wall heat-insulation and heat-preservation mode the best is the self-heat conserving pattern.Self-heat conserving pattern: rely on the thermal property technical indicator of outer body of wall itself, to reach the energy-saving design standard.At present, generally the self-insulation wall material of Shi Yonging is not all reaching design requirements aspect its thermal conductivity.As being the construction material of leading with structural clay tile (use clay fire, tie up arable lands), flyash brick etc.; Because its thermal conductivity height, general thermal conductivity (is built by laying bricks or stones and the thick 20mm sand-cement slurry of each powder in both sides with conventional cement mortar, K＞1.8 down together), formed building enclosure thermal property is poor, can't satisfy the energy-saving design standard, insulation pattern or outer insulation pattern add one deck thermal insulation layer in addition to form composite wall body material in must adopting on the original wall body material; Both made so, also had the problems such as difficulty and matrix material poor durability that cost an arm and a leg, construct.Materials for walls such as gas concrete that generally adopt and for example, though have in light weight, characteristics such as heat insulating, acoustical effectiveness are good, but because the air-entrained concrete building block water-absorbent is strong, water-intake rate is high, easily cause the masonry mortar dehydration too fast, it is full that mortar joint is difficult for, cohesive strength is on the low side, and UNICOM not mutually between the pore in the building block makes the cement and the decortication of body of wall basic unit of primary coat, forms that hollowing causes ftractureing, scaling, thereby influence its heat insulation effect, finally also can't reach the energy-saving design standard.
In recent years, the building energy conservation production development impetus is swift and violent, and the architectural exterior-protecting construction heat insulation system is just promoted the use of, as above-mentioned aerated concrete building block etc., though the thermal and insulating performance of construction wall is made moderate progress, but still be difficult to the requirement that reaches more satisfactory.In addition, also have characteristics such as exquisiteness, loose, light weight, porous, diatomite has been had further exploitation at diatomite.Make stupalith or as the carrier in sterilant and the siccative or be used to prepare waste water conditioner or the chemical catalyst except that being mainly used in, aspect material of construction, be used to make coating, thin fire-resistant coiled material and refractory brick again; They are mainly as the lagging material of boiler, distiller, heat treatment furnace, moisture eliminator etc. and light heat-insulating plate, insulating pipe etc.At publication number is among the CN1038237A, a kind of diatomite that passes through is disclosed, sawdust powder, coal ash, the microporous light-weight hollow-brick that methods such as terra alba and other catalyst and water mixing make, wherein except that diatomaceous usage quantity (being 50～80%) is higher, other industrial raw material such as terra alba etc. have also been used, though, the heat-insulating property of this brick is improved, but cost is higher, and in high-load diatomite, add a large amount of sawdust powder (can up to 30%) and a spot of terra alba (content is 2～8%) and carry out sintering, be difficult to the globality of finished product behind the assurance sintering and thermal property thereof etc.
