Description
Technical field
The present invention relates to preparation method of the inorganic building thermal insulation material of a kind of high-efficient energy-saving environment friendly and products thereof.
Background technology
Be used for mainly being divided three classes of external-wall heat-insulation material at present: the one, the thermoplasticity heat insulating material mainly contains the EPS external insulating system for thinly plastered external wall, and the XPS external insulating system for thinly plastered external wall is netted cast-in-place nothing and is netted cast-in-place system, the composite insulation boards system; The 2nd, the thermosetting heat insulating material comprises polyurethane foam-in-place system, the phenolic board class; The 3rd, inorganic heat insulation material: mainly contain foam glass, the rock wool exterior wall heat-preserving system, or the like.These system fireproof performances are not quite similar, and are specific as follows:
The thermoplasticity heat insulating material: the thermoplasticity heat insulating material is applied in the external wall outer insulation, is present the most perfect the most ripe external thermal insulation system.The burning grade is the B2 level, belongs to from fiery self-extinguishing type.
The thermosetting heat insulating material: in the thermosetting heat insulating material, the fire-protection rating of polyurethane foam also is the B2 level.The fireproof performance of phenol formaldehyde foam is better than polyurethane foam, and its combustibility approaches A level material, is reasonable fireproof heat insulating material in the organic insulation material at present; But system itself is applied in the check that technical experience in the external wall outer insulation does not all also have the elapsed time, the poor stability of system; Particularly the coefficient of thermal conductivity after the polyurethane suction raises greatly; Cause system's heat insulating ability, freeze-thaw resistance, safety reduces greatly.
Inorganic heat insulation material: be representative with rock wool and foam glass again in the inorganic heat insulation material.(about 25 ℃) coefficient of thermal conductivity is usually between 0.036～0.041W/ (mK) under normal temperature condition for rock wool, mineral wool, and itself belongs to the inanimate matter silicate fiber, and is not flammable.
" combustibility is the heat insulating material of A level " mainly is meant the inorganic heat insulation material of glass bead, closed-cell expanded perlite, rock wool, mineral wool, glass wool, cement based or gypsum base inorganic heat insulation mortar and light block self-heat conserving system etc. at present.In general, inorganic material generally can both reach B1 level or the fire protection requirement of A level, but the density of its unit volume is bigger, and coefficient of thermal conductivity is higher, compares with organic insulation material, and its heat preservation and energy conservation effects is poorer.Especially in the cold north, the construction thickness below 10 centimetres is difficult to reach the requirement of code of building energy efficiency.
The inorganic heat insulation mortar of selling on the market now; Combination property is lower; Quality is uneven, is unable to undergo the conscientious inspection of relevant department mostly, and the burning grade that is called inorganic heat insulation mortar equally can not be adopted a casual attitude; Because coefficient of thermal conductivity, raising compressive strength and the workability of some enterprise in order to reduce thermal insulation mortar; Often will come modification by adding multiple organic material, after the organic component in the mortar surpassed certain proportion, inorganic heat insulation mortar people's fireproof performance of speaking approvingly of the most equally also can be had a greatly reduced quality.The increase of thickness has increased the weight of whole heat insulation system, and difficulty of construction has also increased, and material cost also increases thereupon, but security performance has reduced.
On the other hand, inorganic material can be paid the cost of high energy consumption in process of production, and at present, the energy consumption of producing inorganic heat insulation material is higher than the energy consumption of producing organic insulation material.Such as, temperature reaches 100 degrees centigrade just can produce the expandable polystyrene plate, produces rock wool and will melt the back to rock, and temperature will reach more than 1000 degrees centigrade at least ".It is higher to produce the inorganic heat insulation material energy consumption, does not meet the requirement that the speed production mode changes, accelerates the energy-saving and emission-reduction paces.If use the material of combustibility in the External Thermal Insulation System without exception as the A level, reach very high Debao warm nature ability simultaneously again, then the market of heat insulating material will almost become blank.
Therefore, can to reach A level fire prevention again extremely urgent to the appearance of human body and environmentally friendly external-wall heat-insulation material simultaneously for a kind of existing efficient energy-saving heat-preservation.
Summary of the invention
For solving the problems of the technologies described above; The present invention provides a kind of cost of production low, and less energy consumption has extremely low coefficient of thermal conductivity; Can greatly block conduction of heat; Realize the heat preservation energy-saving of building, heat insulation effect is very outstanding, can the natural inorganic mineral material preparation be become the preparation method and products thereof of the inorganic building thermal insulation material of high-efficient energy-saving environment friendly of high-efficiency environment friendly warming plate.
