Abstract
A light-weight insulating compound board is made up through compounding aqueous high polymer modified magnesia kind of cementing material with insulating paint, and features light volume weight, low heat conduction coefficient and high strength.
Description
The present invention relates to a kind of energy-saving building material, particularly a kind of light-weight composite insulating plate and production technology thereof.
Current Building Trade in China development is exceedingly fast, but all kinds of materials for wall and roof insulation sheet material are very backward, basically still based on " Qin brick and Han tile ".This class materials for wall shortcoming of loam brick is a lot, destroy to plough in the production, energy consumption is big, and heaviness during construction, speed be slow, be difficult to mechanization, and heat insulating ability is poor, makes body of wall very thick, has reduced usable floor area.In addition, increasing highrise building adopts the integrated poured cement wall plate of frame construction mostly, and heat insulating ability is poor, must add insulation layer in addition.Therefore, the reform of the walling of China is imperative.Given this, several wall boards arise at the historic moment, and are nearly: foamed cement plate, Foamed Gypsum plate; Or, be aided with flyash, wood chip or string (agricultural residue) based on cementitious material such as cement, gypsum, magnesium oxychlorides.Here, need not each sheet material is done an evaluation, as a whole, most following shortcoming of tool: the big (700～900kg/m of capacity
3), coefficient of thermal conductivity is undesirable, and majority＞0.12W/mk has much more than 0.15w/mk, because intensity is low, sheet material is done very thickly (most be 50mm, also have between 60～100mm).In addition,, be difficult to the test of the time of standing, aspect durability, allow the people carry on a shoulder pole rather and disturb if do to strengthen framework material with wood chip and string.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of prescription and production technology thereof of light-weight composite insulating plate are proposed, the use high polymer is done modification to magnesite class cementitious material and is handled, and based on it, compound with thermal insulation coatings, again this compound by hand or machinery make light-weight composite insulating plate, have that unit weight is light, coefficient of thermal conductivity is little, advantages of high strength.
The light-weight composite insulating plate of indication of the present invention, by thermal insulation coatings and modified adhesive gel material in (1～1.4): the ratio of (1～2) is composited.Here said thermal insulation coatings is grouped into (percentage by weight) by following one-tenth:
Alumina silicate fibre 12～18
Sepiolite 15～22
Swell soil 7～12
Kieselguhr 8～12
Penetrating agent JFC 0.5～1
Water glass 2～3
Expanded pearlite 40～50
Here said modified adhesive gel material, form (percentage by weight) by following composition:
Magnesia 40～50
Magnesium chloride brine (d=1.2～1.25) 35～40
EVA emulsion 6～8
Amino resins 4～6
Production technology of the present invention is as follows:
1. after alumina silicate fibre, sepiolite, swell soil, four kinds of materials of kieselguhr being weighed up by prescription, place troughing, add an amount of water, the weight of water is four times of thermal insulation coatings all material gross weight, add the penetrating agent JFC that weighs up again, soak after 2～4 hours, start beater, pulled an oar 20～40 minutes, add the water glass that weighs up again, continue making beating 10 minutes, add load weighted perlite at last, mix and can obtain thermal insulation coatings, standby.
2. water dissolves magnesium chloride, and the proportion of pressing temperature control solution is between 1.2～1.25, and the technical hydrochloric acid of adding 1% is with standby; By the good magnesia of prescription weighing, add the magnesium chloride solution of proportional quantity again, the preliminary mixing, add modifier EVA resin and amino resins again, fully mix and promptly get cementitious material.
3. in 1: the ratio of (1～1.5), thermal insulation coatings and modified adhesive gel material are mixed, pour in the ready mould, floating deeply, the surface is smoothless, the core material part of sheet material.
4. in 1: the ratio of (1～2), thermal insulation coatings and modified adhesive gel material are mixed, pour in the mould of existing core material, on core material flat, the troweling in beach, just constitute the lining of sheet material.
5. sheet material maintenance in mould got final product the demoulding in 40～48 hours, removable, the stacking in rear in 4 days
Done batch to be tested by above-mentioned prescription and technology, made the test block (totally 10) of sheet material and 80 * 80 * 80mm of 200 * 200 * 20mm, sent the test of architecture engineering material inspection center of Xi'an University of Architecture and Technology, main result is as follows:
Coefficient of thermal conductivity w/mk 0.096
Dry density kg/m
3500～550
Pressure-resistant temp MPa 1.3
Thermal resistance m
2K/W 0.2
800 ℃ of noninflammability are not fired
By above data as can be seen, this sheet material no matter coefficient of thermal conductivity still be aspect such as compressive strength with existing similar sheet material relatively, all be in advanced level.This sheet material all has competitiveness economically with on the performance.
