Abstract

Belonging to the technical field of concrete products and the novel building energy conservation field, the invention relates to a chemical foaming self-thermal insulation building block. The chemical foaming self-thermal insulation building block not only meets the requirements of outer wall envelop masonries, has all indicators meeting the requirements of ''normal concrete small hollow block'' (GB8239-1997) and ''light aggregate concrete small building block'' (GBT15229-2002), and at the same time can meet the outer-wall external thermal insulation requirements, and is in accord with 65% building energy conservation requirements of ''civil building design thermotechnical specification'' (GBT50176-1996). The fireproof grade of the material is grade A. The chemical foaming self-thermal insulation building block can be widely used in the outer-wall self-thermal insulation system of a non-bearing structure, adopts building block mortar special for polymers and a thin layer (with a mortar joint thickness of 3-5mm) building method for building. During building, the building block can protrude from a beam and a column by 40-60mm.Thermal insulation treatment is carried out on beam column and other thermal bridge parts so as to meet the minimum thermal resistance requirement.

Description

Chemical foaming heat insulation building block
Technical field
The present invention relates to a kind of chemical foaming heat insulation building block, belong to concrete product technical field and novel building energy-saving field.
Background technology
Lightweight concrete building block is a great development direction of current building material industry, and it can alleviate building bearing on the one hand, improves the defect of traditional architecture fat beams and columns, deep foundation, and it is raw material mainly with industrial residue on the other hand, energy-conserving profit waste.Under construction, the thermosteresis maximum of building external envelope structure, construction wall reform is the most important part of building energy conservation with body of wall power-saving technology.It is 50-700kg/m3 that current skin masonry adopts holllow building block, air-entrained concrete building block unit weight more, thermal conductivity 0.12-0.20w/m.k.For skeleton construction, at present the air-entrained concrete building blocks that adopt are as infilled wall more, are then incubated outward doing external wall.The outer insulation of external wall adopts at present pastes external wall insulation class and smears building heat-insulating mortar class.External wall outer insulation long construction period, needs scaffolding, due to construction technology error and material processing technique error, easily causes quality unstable, occurs that external wall outer insulation comes off.Public affairs in 2011 disappear and require for [2011] No. 65 external wall outer insulation material to adopt fire resistance rating A level material, and organic external wall outer insulation material can not meet fire protection requirement, is progressively eliminated.Inorganic heat insulation material is because thermal conductivity is low, and under building energy conservation 65% requires, especially in the north, inorganic heat insulation material, because insulation layer thickness exceeds standard, affects safety of structure, and inorganic heat insulation material cannot meet building energy conservation requirement.The object of the invention is to have above-mentioned deficiency for existing concrete building block and insulation, a kind of chemical foaming heat insulation building block is provided, not only meet the requirement of exterior wall enclosure masonry, indices meets " normal concrete small hollow block " (GB8239-1997) and " light weight small insulating concrete building block " (GBT15229-2002) requirement.Can meet external wall outer insulation requirement, meet " covil construction design thermal technology specification " (GBT50176-1996) 65% building energy conservation requirement, the fire-protection rating of material is A level simultaneously.Be widely used in the outer wall self heat-preserving system of non bearing structure, adopt polymkeric substance dedicated building block mortar, thin layer (gray seam thickness 3-5mm) building method is built by laying bricks or stones.The outstanding beam of building block, post 40-60mm while building by laying bricks or stones.The processing that the heat bridge positions such as beam column are incubated, meets minimum thermal resistance requirement.
Summary of the invention
Chemical foaming heat insulation building block of the present invention, prepared by following methods: cement 40-45%wt, rapid hardening and early strength cement 1.0-5.0% flyash 40-45%wt, quartz sand 8-15%wt, whipping agent 2.0-3.0%wt, suds-stabilizing agent 0.5-1.0% wt, stablizer 0.1-0.2%wt, water-resisting agent 0.1-0.4%, anti-fissuring agent 0.1-0.2%wt, accelerating chemicals 0.5-1.0% wt, toughener 0.5-1.0%wt, ratio of water to material 0.5-0.7, water temperature 50 is spent.Chemical foaming heat insulation building block of the present invention, after water, suds-stabilizing agent, water-resisting agent, stablizer should being stirred, adds cement etc. all after powders and anti-fissuring agent, to stir, and adds afterwards whipping agent to stir rapidly and pours in mould, the demoulding in 2 hours after moulding.After plastic covering cloth, within three days, cut by size.Above-mentioned cement is ordinary Portland cement PO32.5, and rapid hardening and early strength cement is 42.5 aluminosulfate cements, and flyash is I level flyash, and quartz sand fineness is 40-100 order.The excellent hydrogen peroxide of above-mentioned whipping agent, concentration >=27.5%, can be also sodium bicarbonate, carbonization calcium powder, phosphoric acid.The preferred perstearic acid sodium of above-mentioned suds-stabilizing agent, calcium stearate, Magnesium Stearate, water glass, sodium oleate.Aforementioned stable agent preferably phosphoric acid, oxalic acid, hydrochloric acid, formic acid, magnesium chloride.The preferred silicone resin of above-mentioned water-resisting agent, silicone oil, silicane, fatty acid salt.Above-mentioned anti-fissuring agent vinylon fiber, polypropylene fibre, wood fibre.Above-mentioned toughener preferably polyethylene alcohol, polyvinyl formal, urea-formaldehyde resin, ACRYLIC EMULSION, VAE emulsion, styrene-butadiene latex.The preferred unslaked lime of above-mentioned accelerating chemicals, high strength gypsum, Quilonum Retard, trolamine, two or more in Sodium sulfate anhydrous.min(99), nitrite.
