Description
Technical field
The present invention relates to a kind of expanded perlite fireproof heated board, particularly to fast rigid composite gelled material modified pearl rock warming plate of one and preparation method thereof.
Background technology
Along with the fast development of national economy, improving constantly of living standards of the people, the consumption of the energy is also increasing, and in the total energy consumption of China, building energy consumption is one of main aspect of China's energy consumption.According to relevant report, in China's newly-increased house architectural area every year, major part is built for highly energy-consuming, and existing building nearly 90% is built for high energy consumption.The whole nation annual power consumption of building accounts for more than the 20% of China's generated energy, and unit construction area power consumption is the several times of developed country.Wherein main cause is that fall behind relative with correlation technique of China's building heat preservation function imperfection is caused.
For energy-saving and emission-reduction, reducing building energy consumption, current most common method is to install heat insulation layer additional at exterior wall.What existing insulation material adopted mostly is low-density loose porous material, because convection current and the conduction of heat are played very big barrier effect by the internal air filled and close, thus realizing the effect of insulation.
The mainly organic insulation material that China's present stage uses, as: polystyrene block EPS, extruded polystyrene board XPS, granular polystyrene, spraying polyurethane SPU and polyurethane PU hard bubble.Organic insulation material has feature lightweight, good effect of heat insulation, easy construction.But existing organic insulation material also has its unavoidable shortcoming: inflammable, although the fire protecting performance that existing relevant art improves organic material reaches flame retardant effect, but when the intensity of a fire is bigger, flame treatment material remains to be ignited, some material is also possible to produce a large amount of toxic smog, increases escape personnel when fire occurs and dies like a rat or damped probability.After additionally organic material is heated in a fire, mechanical property reduces rapidly and is also possible to increase its risk come off, and causes unnecessary loss.And inorganic heat insulation material is just absent from such shortcoming, its fire resistance rating is A1 level, does not burn, is not fuming and Heat stability is good, loses intensity without because of high temperature.
Therefore, from the overall situation of building energy conservation and people life property safety, substitute, with outstanding inorganic heat insulation material, the problem that organic insulation material becomes extremely urgent.
Inorganic heat insulation material is based on rock wool, expanded perlite, they have acid and alkali-resistance, corrosion-resistant, stability is high, easy construction, applied widely, insulation suitable in various body of wall basic unit materials and variously-shaped complicated body of wall, the most important thing is that its fire protection flame retarding safety is good, fire-protection rating is required strict place by other to can be widely used for intensive house, public building, large-scale public place, combustible and explosive area etc..But, insulation and the hydrophobicity performance of existing inorganic heat insulation material are relatively poor, and resistance to compression, rupture strength are not high, and durability is bad, under relative humidity environment easily defeated and dispersed, for exterior-wall heat insulation on long terms, there are major safety risks, and many with waterglass for main binding, its pH value is more than 14, in strong basicity, easily cause the exterior wall accumulation of salt in the surface soil, grow dim and rate of drying is slow, it is necessary to mass energy is dried.This constrains its development significantly.
Therefore, a kind of replacement warming plate with waterglass for main binding material is researched and developed and density is low, intensity is high, the insulation material that do not fire of good endurance becomes the practical problem currently needing solution badly.
Summary of the invention
For existing problem, it is an object of the invention to provide a kind of fire protection flame retarding, bending and compressive strength is high, wet wet strength raises, not the accumulation of salt in the surface soil, good endurance, fast firmly quick-drying, without drying, hydrophobic effect is good, the fast gravity die Binder Materials modified pearl rock warming plate of excellent thermal insulation performance.The preparation method that present invention also offers this kind of warming plate.
To achieve these goals, the technical scheme is that a kind of fast rigid composite gelled material modified pearl rock warming plate, it is characterised in that: it is made up of Binder Materials, water repellent powder and expanded perlite；
Wherein Binder Materials is at least one in alumina cement, sulfur aluminum cement, ordinary portland cement；
Be preferably two kinds and more than.
In such scheme, the parts by weight of each component are: water repellent powder 1-8 part, expanded perlite 70-100 part；
Binder Materials: any one in alumina cement, sulfur aluminum cement, ordinary portland cement is as major ingredient, and the parts by weight of described major ingredient are 60-90 part, and all the other are 0-20 part.
In such scheme, described Binder Materials also includes Gypsum Fibrosum.It is to say, Binder Materials is composite gelled material, the mixing of at least one and Gypsum Fibrosum in alumina cement, sulfur aluminum cement, ordinary portland cement, improve warming plate durable, from dry, fast firmly quick-drying, insulation, resistance to compression, fold resistance.
In such scheme, according to parts by weight, the amount of Gypsum Fibrosum is 1-10 part.
In such scheme, the following raw material of parts by weight prepare: alumina cement 1-20 part, sulfur aluminum cement 1-20 part, ordinary portland cement 60-90 part, Gypsum Fibrosum 1-10 part, water repellent powder 1-8 part, expanded perlite 70-100 part.
In such scheme, described water repellent powder is at least one in calcium stearate, silylation powder, organosilicon powder.
Preferred: the unit weight of described expanded perlite is 70-105kg/m3, room temperature heat conductivity is 0.03～0.04w/m.k.
Preparation method is: a kind of fast rigid composite gelled material modified pearl rock warming plate preparation method, it is characterized in that: by each raw material of Binder Materials described in any one of embodiment 1-8 by dry powder mixing plant mix homogeneously, again with expanded perlite and water repellent powder mix and blend, water spray stirring, obtain half-dried material, it is then pressed into type, and naturally dries and get final product.From dry, quick-drying, preparation technology is simple.
The invention has the beneficial effects as follows: fast gravity die Binder Materials modified pearl rock warming plate of the present invention with expanded perlite be heat insulation function aggregate, fast gravity die Binder Materials is for binding agent, the warming plate making the present invention have excellence durable, from the characteristic such as dry, fast firmly quick-drying, insulation, resistance to compression, anti-folding, hydrophobic, fast firmly quick-drying, chance water intensity that obtained pearlite heat-insulation plate has other inorganic heat insulating pearlite material incomparable go up not down, with the building same life-span, excellent in mechanical performance, the advantage of fireproof heat insulating.Heat conductivity≤the 0.070w/m.k of warming plate of the present invention, comprcssive strength >=1.23MPa, rupture strength >=0.40MPa, density is less than 300kg/m3。
