Description
Technical field
The present invention relates to a kind of straw heat-insulating board and preparation method thereof, belong to building material field.
Background technology
Agricultural crop straw is the byproduct that in agriculture production, quantity is maximum, and in recent years, rural economic development was very fast, and the improvement of house condition, the family of 80% employs electrical equipment and liquefied gas, and some use biogas, warming turns to electricity consumption and uses coal.Therefore, peasant reduces year by year for the rate of utilization of stalk, the direct burning even had, and like this, not only can cause very large pollution to environment, cause larger financial loss sometimes, and according to data introduction, the stalk comprehensive utilization rate in the whole nation is about 24%.Agricultural crop straw is a kind of important physical resources, disposal irrelevantly, not only cause the wasting of resources, more seriously environment is damaged, how to carry out stalk to transform on the spot and deep processing, become the problem that assistant officer is to be solved, improve the utilization of stalk, to the development of sustainable rural economy, far-reaching influence must be produced.Therefore, the straw utilization mode that reform traditional falls behind, development straw circulating economy is imperative, how to solve the reasonable whereabouts of stalk, effectively Utilizing question and seems particularly urgent, in all parts of the country all in new way, the novel method of trying to explore straw circulating recycling.Take stalk as the straw heat-insulating board of core, achieve and turn waste into wealth, reduce the cost of building materials, in addition, the top layer of straw heat-insulating board adopts gelling material, the concrete heat-insulation and heat-preservation of this gelling material itself and concrete consistency is good, coagulate soon, characteristic hard soon, therefore, this straw heat-insulating board, can avoid that conventional vacuum plate price is high, inflammable, heat insulation effect is poor, the defect of the not aspect of constructing easily.In addition, the warming plate utilizing straw standby have the feature of " super insulation ", humidity high, contribute to HUMAN HEALTH.
Summary of the invention
The present invention is directed to the problem of above-mentioned proposition, object is to propose a kind of method that effectively can utilize agricultural crop straw, and utilizes stalk to prepare the environmental protection straw heat-insulating board with some strength, heat-insulation and heat-preservation, fire-retardant, mildew-resistant for core.
The present invention is realized by following technical scheme:
A kind of straw heat-insulating board, be made up of the raw material of following weight part:
Described stalk is common agricultural crop straw, and comprise maize straw, wheat stalk, rice straw, broomcorn straw etc., stalk length is 4-5cm.
Described monovalence dihydrogen phosphate powder is selected from the one in potassium primary phosphate, primary ammonium phosphate, SODIUM PHOSPHATE, MONOBASIC, monometallic.
Described metal oxide is selected from the one in magnesium oxide, zinc oxide, aluminum oxide, calcium oxide, barium oxide.
Described borate selects the one in sodium tetraborate, sodium tetraborate potassium.
The granularity of described monovalence dihydrogen phosphate powder, metal-oxide powder and borate powder is 0.3-0.5mm.
The preparation method of described modified kaolin is as follows: calcine 3-5h at kaolin being placed in 680-720 DEG C, being cooled to normal temperature, to be placed on concentration be in the hydrochloric acid soln of 10-15%, heating in water bath is to 70-80 DEG C, insulation 30-40min, filter, with distilled water, residue washing is extremely neutral, dry, then the γ-aminopropyl triethoxysilane of sepiolite powder, the vermiculite power of 4-6%, the asbestos powder of 3-5%, the calcium lignin sulphonate of 2-3% and the 0.5-1% being equivalent to kaolin weight 5-10% is added, speed lapping 20-30min; Finally add the plant ash being equivalent to the silicon sol of kaolin weight 10-15%, the tripoly phosphate sodium STPP of 3-5% and 5-10%, high-speed stirring 10-15min, dry, calcine 1-2h at 960-1120 DEG C, be cooled to normal temperature, pulverize and sieve.
The preparation method of straw heat-insulating board, comprises the following steps:
(1) the straw utilization epoxy glue of 4-5cm, jade powder and pearlife are pressed in a fixed mold have certain size and the good stalk board of mildew resistance, this stalk board is as the core of warming plate;
(2) monovalence dihydrogen phosphate powder, metal-oxide powder, borate powder and modified kaolin are put into agitator for cement mortar and stir 2-4min, it is made fully to mix, then water is added, stir 20-30s, pour in the Standard Module that stalk board is housed that to carry out top layer coated into, the demoulding after 10-15min, normal temperature maintenance 2h can obtain a kind of straw heat-insulating board.
Advantage of the present invention:
The present invention mainly comprises two parts, core layer and coating layer, core layer is mainly first shaping stalk at random by the effect of epoxy glue, jade powder and pearlife, and there is certain mildew-resistant heat insulation effect, for surface coated inorganic coagulation material, there is fire-retardant, insulation, water-fast, rapid shaping, high-strength excellent properties, greatly evaded the shortcoming of short, inflammable, poor water resistance of traditional stalk board life-span.
One aspect of the present invention solves the problem of stalk poor efficiency, and meet the strategic requirement of national development recycling economy on the other hand, and production method is simple to operation, cost is low, environmental protection; The straw heat-insulating board prepared has the excellent properties such as rapid shaping, heat-insulation and heat-preservation, fire-retardant, mildew-resistant, no matter be applied in building field or other association areas in the future, all has very bright and clear market outlook.
