Abstract
The invention disclosed a kind of glassified superbead incubation and heat insulation compound material which is a kind of wall adiabator. The ingredients of the material include 40-60 parts of high aluminium cement, 40-60 parts of glassified superbead, 3-10 parts of polyvinyl alcohol, 1-3 parts of polyphenylene thiol ether, 0.3-1.2 parts of methyl cellulose, 1-2.5 parts of calcium hydroxide and 1-5 parts of xylon. The invention has many advantages such as convenient to construct, good effect of incubation and heat insulation, good ability to stop burning and prevent fire, small volume weight and light mass.
Description
One, technical field
The present invention relates to building wall material, particularly energy-saving heat-insulating wall material is made the field.
Two, background technology
Energy-saving building technology not only can be saved the energy, cuts down expenses, and improves thermal environment in indoor winter, transforms the constant indoor temperature environment summer, saves the consumption of the energy, reduces environmental pollution and Greenhouse effect, keeps ecological balance and Sustainable development.Building energy conservation has become the problem of whole world common concern and attention.
The Chinese government puts on agenda building energy conservation, and has proposed energy-conservation hard and fast rule to newly building the project of building, and the former building of haveing been friends in the past has been proposed the requirement of transforming.
From the main insulating material of existing structure body of wall, glass wool (as glass fiber blanket, block of glass wool, glass cotton blanket, glass wool band etc.) generally commonly used, polystyrene foam plate and urethane foam-in-place plate etc.Adopt the essential structure of the heat-preserving wall of polystyrene board to be: basic unit's metope, caking agent, polystyrene board, reinforced grid cloth, priming paint, putty, finish coat.The essential structure of polyurethane coating External Walls Heating Insulation is: basic unit's body of wall, polyurethane primer, polyurethane insulation coating, front mortar, lightweight leveling layer, anticracking grout composite gridding cloth, putty, exterior coating (if the exterior wall tiling, it is fixed then to add anchoring in the alignment material layer in addition).The glass wool material exists construction trouble, the relatively poor problem of heat-insulating property.There are the construction technology complexity in polystyrene foam plate and polyurethane foam board, wall weight big (adding outer raw material), and cystose easily comes off, and easily shrinks, and is inflammable, and the burning back produces defectives such as poison gas.
Chinese patent literature discloses a kind of " hollow centered microbead portland cement " (CN1061014), and it is to be mixed by Portland clinker, gypsum and cenosphere.This cenosphere utilizes sorting unit to separate from flyash.Chinese patent literature has also disclosed a kind of " energy-saving and heat-insulating material ", and it is made up of magnesium oxide, material (as: silicon-dioxide), coal fly ash hollow micro bead, perlite, mica powder, caking agent and vegetable-protein glue, modified-cellulose etc.Above-mentioned two kinds of lagging materials have low price, advantage that cost is low, but remain at heat preservation and insulation good, not ideal enough inadequately, with the not good enough weakness of sticking power of basic unit's body of wall.
Therefore, exploitation new high-efficiency heat preserving and insulating material is imperative.
Three, summary of the invention
The object of the present invention is to provide a kind of easy construction, thermal and insulating performance is better, and is fire-retardant, the vitrified micro bubbles heat preservation and insulation composite material of high-and low-temperature resistance.
The object of the present invention is achieved like this: a kind of vitrified micro bubbles heat preservation and insulation composite material, and it is made up of following raw material by weight:
High-alumina cement 40～60; Glass bead 40～60; Polyvinyl alcohol 3～10; Polyhenylene thioether 1～3; Methylcellulose gum 0.3～1.2; Calcium hydroxide 1～2.5; Xylon 1～5.
The granularity of described polyvinyl alcohol is the 320-400 order.
In the technical solution of the present invention, polyvinyl alcohol is the macromolecular compound that is formed through saponification by polyvinyl acetate (PVA).The polyhenylene thioether is made through polycondensation by santochlor and sodium sulphite.It is a kind of thermoplastic resin, and to sulfuric acid, hydrochloric acid, phosphoric acid, hydrofluoric acid, sodium hydroxide, potassium hydroxide, hydrogen peroxide etc. are constant.To little change of nitric acid or decomposition.Be insoluble to common organic solvents, good thermotolerance and self-extinguishing are arranged.Heating is not decomposed for 450-500 ℃ in air.(mixture of the present invention in use under the alkaline condition that calcium hydroxide (as promotor) exists, adding water mixes, be put on basic unit's body of wall, as thermal insulation layer), after polyhenylene thioether and the polyvinyl alcohol generation crosslinking reaction, heat-resisting being increased to more than 600 ℃, and adhesiveproperties further improves, as, the pressure of single polyvinyl alcohol is cut bonding strength (7 days): 7.5MPa, and the pressure of the cross-linking agent of polyvinyl alcohol and polyhenylene thioether is cut bonding strength and is brought up to 12.5MPa.
The main chemical compositions of glass bead (also being vitreous light hollow microballon) is titanium dioxide two silicon and aluminium sesquioxide, and it is a kind of light-weight inorganic non-metallic material, and diameter is between the 0.01-400 micron, and outward appearance is greyish white or grey, good fluidity.Examine under a microscope to having silvery white glossy spheroid, hollow has hard shell, is N in the shell
2Or CO
2Rare gas element, wall thickness are 10% of diameter.Its characteristics are as follows: tap density is little: float pearl at 0.3-0.45g/cm
3, microballon is at 0.9-1.2g/cm
3Between; Intensity height: can bear 1000-7000kg/cm
2Compressive strength; Heat-insulating sound-insulating: thermal conductivity 0.036-0.054w/mk; Low-shrinkage (manufacturer is as the smart inferior nano material of: Shanghai IC company limited, Dongying ten thousand Jia Qingzhicailiaochang etc.).
The inventor if substitute high-alumina cement with silicate cement, can cause the too slow problem of whole thermal insulation layer material cured through experiment discovery repeatedly.Methylcellulose gum is swelled into translucent viscous colloidal solution in water, to litmus neutral.Methylcellulose gum (being Walsroder MC 20000S) belongs to modified fibre, and the polymerization degree of the ethyl cellulose in the modified fibre (being hemicellulose) is little more a lot of than methylcellulose gum, should not be used as this materials for wall.
The present invention as the essential structure of heat-preserving wall is: basic unit's body of wall, thermal insulation layer of the present invention (lagging material of the present invention adds water and mixes, and scrapes to be put on the body of wall to form), priming paint, putty, finish coat.
