Abstract
The improved inorganic adhesive is prepared through such steps as oxidation reaction of phosphoric acid or the mixture of phosphoric acid and sulfuric acid on hydrogen, addition of SiO2, diluting with water and regulating pH value to 5-7 with alkali solution and features its characteristics general inorganic adhesive does not have and wide application range such as wet production of refractory fibrous products.
Description
The present invention relates to the inorganic adhesive field.
Characteristics such as in the prior art, that inorganic adhesive has is high temperature resistant, have no side effect are applicable to a lot of high temperature adhesives occasions, but because it is acid big, corrodibility is big, user mode is difficult for adjusting, and its application is subjected to restriction to a certain degree, and some required field but can not be used., attempt not achieve success so far always in effort as Shandong Zibo city Luyang energy-saving material limited-liability company with the organic binder bond in the inorganic adhesive replacement refractory fibre product wet production.The tackiness agent that the wet production of refractory fibre product is used, always adopt organic binder bond, as methylcellulose gum, starch, polyvinyl alcohol etc., this class tackiness agent heatproof is poor, when use temperature surpasses 300 ℃, tackiness agent just begins to decompose gradually, loses bounding force, makes goods lose anchorage force, fall to the bottom of thermal insulation layer, reduce heat-insulating property greatly, the time is not long, just needs repair and replacement, so, temperature range is little, and work-ing life, weak point became fatal shortcoming, is badly in need of using the tackiness agent suitable with the refractory fibre heatproof to replace.
The object of the present invention is to provide a kind of improved inorganic adhesive and preparation method, this kind tackiness agent can be applied to multiple bonding occasion, especially can be used for the wet production of refractory fibre product.
Purpose of the present invention realizes by following scheme:
This inorganic adhesive mainly contains A solution, silicon-dioxide and water, and its weight proportion of composing is: A solution: silicon-dioxide=1.5～3: 1, (A solution+silicon-dioxide): water=1: 6～10.5
The pH value of product is 5～7,
Wherein, A solution is the mixed solution of phosphoric acid or phosphoric acid and vitriolic mixing acid and aluminium hydroxide, and its weight proportion of composing is (phosphoric acid+sulfuric acid): aluminium hydroxide=5～9: 1.
In more than forming, used phosphoric acid and sulfuric acid are that industrial concentrated acid is better, and the weight proportion of composing of two acid is: phosphoric acid: sulfuric acid=1: 0～1.5.Optimum proportion is 1: 0.6～1.2.
Inorganic adhesive preparation technology of the present invention is simple, is summarized as follows:
Phosphoric acid and sulfuric acid are mixed, add aluminium hydrate powder, treat that aluminium hydroxide dissolves fully after, add silicon dioxide powder, dilute with water is transferred pH value to 5～7 with alkali lye more then.
In preparation process:
(1) phosphoric acid and sulfuric acid mix, and two kinds of acid excite mutually, the active increasing, and reaction is carried out quicker more thoroughly, to obtain more adhesive component---aluminium dihydrogen phosphate, aluminium hydrogen sulfate, phosphoric acid hydrogen two aluminium etc.In actually operating, in order to add fast response, mixing acid can also be heated, be advisable with the near state of boiling.
(2) for well, thin more naturally good more, so that the reaction dissolving, wherein, the fineness of aluminium hydroxide is crossed 80 mesh sieves at least with fine powder for aluminium hydroxide that adds in the reaction and silicon-dioxide, and the fineness of silicon-dioxide is crossed 200 mesh sieves at least.
(3) transfer the used alkali lye of pH value, can be the aqueous solution of sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide etc., its concentration affects is little, and we have adopted 10～30% aqueous sodium hydroxide solution.
The inorganic adhesive of the present invention that above technology makes can be used for the wet production of refractory fibre product, and using method is as follows:
(1) water soaks into fiber, and it is unfolded evenly, and general 1 part of fiber needs 25～35 parts of hydrations suitable.
(2) with in the fiber injection moulding mould that soaks into, different moulds can make different types of product, as flame-retardant fibre board, refractory fibre brick, refractory fibre stone or metal plate for standing a stove on as a precaution against fire, refractory fibre shell etc., treat cloth cotton evenly after, the suction filtration moulding, moisture controlled is less than 40%.
(3), front suction filtration anti-with inorganic adhesive of the present invention, total amount of liquid is controlled at about 50～60%.
(4) oven dry promptly gets refractory fibre product.
Inorganic adhesive of the present invention compared with prior art has the following advantages:
(1) this inorganic adhesive has all characteristics of common inorganic adhesive, as high temperature resistant, nontoxicity etc. are because of taking special process to improve its user mode and having adjusted its potential of hydrogen, its range of application is enlarged, especially can be used for the production of refractory fibre product.
(2) price of phosphoric acid is 5～6 times of sulfuric acid price, introduces the gas washing in SA production inorganic adhesive in batching, has reduced the production cost of tackiness agent.
(3) this tackiness agent is used for the production of refractory fibre product, replace organic binder bond, enlarged the kind of refractory fibre product, improved the use temperature of refractory fibre product, and intensification along with refractory fibre product, silicon-dioxide wherein and alkaline constituents act on to some extent and generate silicate, thereby have increased the intensity of refractory fibre product.
(4) used organic binder bond is compared in this tackiness agent and the refractory fibre product production, and production cost is low, and preparation technology is simple, and using method is easy.
(5) intermediate product of this inorganic adhesive can replace mutually with general high-temperature adhesives such as aluminium dihydrogen phosphate, phosphoric acid hydrogen two aluminium etc. and use.
The present invention is further illustrated below in conjunction with specific embodiment.
