Abstract
The invention relates to an elastic inorganic thermal-insulation material, which comprises fly ash fibers and a cement clinker, wherein the cement particles separated at the fiber overlapping position slide in the fiber gap so as to produce elasticity. According to the present invention, the material has good mechanical strength, the burning grade is the grade A homogenization, the thermal conductivity is 0.035-0.043, the bulk density is 80-150, and the material can be used in the fields of building, thermal insulation, fire prevention, fire retardation, sound absorbing and the like.
Description
Technical field
The present invention relates to a kind of preparation method of elastic inorganic heat preserving and insulating material.Belong to silicate material class, be applicable to the fields such as building, insulation, heat insulation, fire prevention, fire-retardant, sound-absorbing.Material combustion grade is A level homogeneous material, and between thermal conductivity 0.035 to 0.043, unit weight is between 80 to 150.And there is good physical mechanical strength.
Background technology
At present, the organic aggregate of the many uses of elastic inorganic material, organic adhesive etc. realize the elasticity of inorganic materials.This technology produces flue gas when material runs into high temperature or burning, even reduces burning grade.The present invention uses a large amount of space in material structure, allows the particle of the separation of fiber lap-joint slide between fiber gap and produces elasticity.The present invention and prior art have remarkable difference.This light material thoroughly can solve the inflammable problem of lagging material in heat insulating application.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of elastic inorganic heat preserving and insulating material, its scientific formulation, processing step is reasonable, low production cost, have both the Common advantages of organic and inorganic material, realize fire-retardant while heat insulating, the function of heat insulating is provided under fire-retardant guarantee prerequisite, and there is unit weight and the mechanical property of familiar organic materials.
Fly ash in electric power plant after desulfurization often carries the residual of desulfurization thing, and these active substances can change the cement character of mix with it and then affect concrete properties, and this change brings very large impact to original not wide in range flyash application channel.Especially remarkable in the Xinjiang of rich coal resources.But when the fly ash in electric power plant after desulfurization is applied to coal ash fiber production, impact is but positive.The present invention will widen the application of this coal ash fiber.
The object of the present invention is achieved like this: a kind of elastic inorganic heat preserving and insulating material is characterized in that being made up of following process steps:
1, in the water of 10-100 part, add 0.25 part of liquid anion tensio-active agent, fully add 1.25-25 part superfined flyash fiber after dispersion; 25-75 part coal ash fiber; 25-75 part cement clinker, 2, above-mentioned raw materials fully stirs and stops after obtaining the pre-feed of budget volume stirring, 3, the pre-feed that above-mentioned abundant stirring completes adds mould, and 4, above-mentioned mould to become quadratic function to load negative pressure domain of function at 0.01-0.1Mp vacuum-drying 85-185 degree Celsius of dry 1-24 hour with pressure in vacuum room with the time.The normal maintenance of cooling and demolding obtains elastic inorganic heat preserving and insulating material.
Embodiment
A kind of elastic inorganic heat preserving and insulating material, is made up of the following step:
1, in the water of 100 parts, add 0.25 part of liquid anion tensio-active agent, fully obtain liquid 100.25 parts of dispersion liquids after dispersion, 2, prepare 12.5 parts of superfined flyash fibers; 50 parts of coal ash fibers; 50 parts of cement clinkers, 3, raw material described in step 2 is added in the dispersion liquid of step 1 and fully stir, 4, calculate and measure above-mentioned 212.75 parts of mixture volumes and obtain stopping after the pre-feed of budget unit weight volume stirring, 5, the pre-feed that above-mentioned abundant stirring completes add ready enter mould, 6, above-mentioned mould to become quadratic function to load negative pressure domain of function in 0.01-0.1Mp vacuum-drying with pressure in vacuum room with the time, keep 125 degrees Celsius 4 hours.The normal maintenance of the negative pressure demoulding is gone to obtain elastic inorganic heat preserving and insulating material after cooling.
