Abstract
The present invention is a flexibly thermal insulation material made of compound silicate, with aluminum silicate fiber, sepiolite cashmere, chrysotile, perlite powder is principal constituent, after auxiliary added ingredients mixed together slurrying such as silicon sol high-temperature agglomerant, sulfonate type whipping agent, oxalic acid and first hydroxyl Mierocrystalline cellulose and adorning mould, first low temperature is finalized the design through the foaming back of heating up after removing most of moisture again.
Description
What the present invention relates to is the compound lagging material that contains some kinds of silicate compositions, particularly a kind of lagging material with flexible section characteristics.
In various silicate lagging materials, divide the branch that coating type, hard section bar type and flexible section can be arranged with its proterties.As Chinese patent 88100561.4 introductions is a kind of by aluminum silicate fiber and perlite powder or the compound hard type lagging material that becomes of cenosphere powder.The Japanese Patent spy opens clear 55-71684 and has announced a kind of by the compound ceramic fiber blanket that becomes of ceramic alumina fiber and alumina-silicate ceramic fibre.German Patent 2537345 has been introduced a kind of heat-insulation and heat-preservation felt that is formed by cellulosic aluminum oxide, boron trioxide, zirconium dioxide, titanium trioxide or silicon-dioxide and gelationus silicon-dioxide gluing.Though the lagging material of various trait has characteristics separately, from convenient transportation, convenient construction uses and is convenient to material recycling angle and says, flexible section all has obvious superiority as various insulation quilts etc.
From the material composition that uses, what present various lagging materials generally adopted is pure aluminium silicate, diatomite, perlite, silicon-dioxide or other analogue, and takes with fibrous and granulate material compound form mutually more.
Sepiolite based on the Magnesium Silicate q-agent composition is a kind of fibrous clay mineral, and its specific surface area is big, and adhesive power is strong, but is just to be used nearly for some time as the composition of lagging material.As " New Building Materials " 92(4) 9-12 introduced a kind of follow-on two-pack sepiolite thermal insulation coatings, added expanded perlite granule in the coating of former single sepiolite composition, improved the use properties of some aspect.But as the coating type lagging material, it has all the time and uses inconveniently, and dry setting time is long, easily comes off in the use, and the Maintenance and Repair that are not easy to the equipment that is used with problem such as can't reuse.
The objective of the invention is to provides a kind of and contains the sepiolite composition for addressing the above problem, and has the construction environment of not being subjected to and use the object restriction arbitrarily to shear, and can reusable flexibly thermal insulation material.
Lagging material of the present invention has taked to generally acknowledge at present the comparatively ideal fibrous form that matches with granulate material equally, its main component (weight part) is: aluminum silicate fiber 33-37, sepiolite cashmere 38-42, swelling perlite powder 15-19, chrysotile 6-10, silicon sol high-temperature agglomerant 2.9-3.1, sulfonate type whipping agent 1.9-2.1, oxalic acid and each 1.4-1.6 of first hydroxyl Mierocrystalline cellulose.Form by these and to be not difficult to find out that the fibre composition in the lagging material of the present invention occupies significant proportion, and be several proterties fibrous materials different with characteristics.Wherein the aluminum silicate fiber that thermal conductivity is little be various lagging materials generally adopt, sepiolite cashmere adsorptivity, adhesive power, rheological and the distinct advantages that the aspect had such as high temperature resistant and anti-salt property be other filamentary material can't be obtained, the chrysotile composition can help slurrying.The result that the complementary composition cooperatively interacts on these appearance characters and the internal performance has improved heat-insulating property.Increasing substantially of fibrous material total amount ratio also is to make the important assurance that has the flexibility of the parcel of can reeling after the lagging material moulding.
Another important difference of lagging material of the present invention and aforementioned present various lagging materials also is the direct dehydration shaping of the mixture of perlite powder shape particulate material and various filamentary materials not to be become product, but remakes the type-approval process of just finishing product after the foaming that once heats up is handled after need removing most of moisture earlier.Product after handling like this under the high temperature user mode along with the decomposition of various organic ancillary components with disappear and unlikely heat-insulating property has been affected greatly positive effect.For example identical with composition but only be that the thermal conductivity detected result of thermal insulation coatings under differing temps of direct mixed form is as follows to lagging material of the present invention:
| Material of the present invention | The contrast thermal insulation coatings | |||||||||
| Medial temperature ℃ | 39.3 | 272.7 | 406 | 562.4 | 649.0 | 70 | 289 | 377 | 533 | 580 |
| Thermal conductivity (W/cm.k) | 0.0514 | 0.0750 | 0.0912 | 0.123 | 0.143 | 0.085 | 0.103 | 0.112 | 0.142 | 0.150 |
In the various complementary added ingredients that uses in lagging material of the present invention, the silicon sol high-temperature agglomerant is the bonding component that all will use usually in the various silicate lagging materials.The sulfonate type whipping agent belongs to the anionic foaming ingredient, and wherein best with the effect of using succsinic acid two hot sodium sulfonates, it also can have the effect of usually said fast penetration enhancer simultaneously.Oxalic acid and first hydroxyl Mierocrystalline cellulose can play the tenderizer effect in the manufacturing processed of lagging material of the present invention, in addition, first hydroxyl Mierocrystalline cellulose can also have auxiliary foaming effect.Except that these main components, can also increase other desirable proper composition according to actual needs.For example add with the color that can adjust the lagging material finished product behind the whitening agent of 1.9-2.1 part (weight) more satisfied.
Lagging material of the present invention during fabrication, can be earlier with various fibering compositions, fully soak as composition waters such as aluminum silicate fiber, sepiolite, chrysotiles, for example can soak 1 day or the longer time, then other particle powder and auxiliary added ingredients are adorned mould after the slurrying according to a conventional method.Earlier be lower than dewater under the blowing temperature be not more than 20% to water content after, foaming back typing again heats up.No matter resulting lagging material is to store, transport or construct can arbitrarily curl, wrap up, tie up and shear when using.Its outward appearance mostly is the grey that the depth does not wait, and density is about 140 kilograms per cubic meter, and water ratio is about 0.8%, the about 0.26MPa of tensile strength, the linear shrinkage when being heated to 1000 ℃ about 4.7%.Because can arbitrarily shear the back according to the shape, the big or small needs that use object when practice of construction uses in the Apparatus for strapping packages mode, not only flexible, also be convenient to use objects such as equipment, pipeline and carry out repair and maintenance at any time, but also lagging material is reused.
What below introduce is the example of content of the present invention, but the related scope of content topic of the present invention is not limited only to this example.
35 parts of (being weight) aluminum silicate fibers, 40 parts of sepiolite cashmeres and 8 parts of chrysotiles are incubated immersion after at least 24 hours with boiling water, add 17 parts of swelling perlite powders, 3 parts of silicon sol high-temperature agglomerants, 2 parts of succsinic acid two hot sodium sulfonates, 1.5 part oxalic acid and 1.5 parts of first hydroxyl Mierocrystalline celluloses, behind 2 parts of whitening agent, conventional stirring pulping.Adorn mould then, be not more than 20% in dewatering under the temperature that is lower than boiling point to water ratio after, heat up foaming and last typing promptly obtain a kind of flexibly thermal insulation material of the present invention.
