Abstract
The invention discloses a novel straw insulation board, and the straw insulation board is prepared from the following raw materials in parts by weight: 40-80 parts of straw, 5-20 parts of epoxy glue, 1-10 parts of univalent dihydric phosphate powder, 3-20 parts of metallic oxide powder, 0.5-5 parts of borate powder, 3-6 parts of jade powder, 8-12 parts of pearlite, 5-10 parts of modified kaolin and 30-50 parts of water. The straw insulation board comprises a core material layer and a cladding layer, the core material layer is mainly prepared by press-forming the epoxy glue, the jade powder, the pearlite and the straw, the surface cladding layer is obtained by mainly uniformly cladding an inorganic cementing material with an adhesion effect on the surface layer of the straw board, and therefore, the novel straw insulation board using the straw as a board is obtained. The novel straw insulation board has excellent performances of fast forming, preserving heat and insulating, flame retarding, mould proofing and high strength, and has a clear market prospect whether being applied to the building field or other related fields in future.
Description
Technical field
The present invention relates to a kind of heat-insulation board made by straw and preparation method thereof, belong to building material field.
Background technology
Agricultural crop straw is the byproduct of quantity maximum in agriculture production, and in recent years, rural economic development was very fast, the improvement of house condition, and 80% family has been used electrical equipment and liquefied gas, some use biogas, warming turns to electricity consumption and uses coal.Therefore, peasant is for the rate of utilization reduced year by year of stalk, and the direct burning even having, like this, not only can cause very large pollution to environment, causes sometimes larger financial loss, and according to data introduction, the stalk comprehensive utilization ratio in the whole nation is in 24% left and right.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 do well stalk transforms and deep processing on the spot, becomes assistant officer's problem to be solved, improves the utilization of stalk, development to sustainable rural economy, must produce far-reaching influence.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 utilizes problem to seem particularly urgent, in all parts of the country all in new way, the novel method of trying to explore straw circulating recycling.The heat-insulation board made by straw that the stalk of take is core, realized and having turned waste into wealth, reduced the cost of building materials, in addition, the top layer of heat-insulation board made by straw adopts novel gelled material, the concrete heat-insulation and heat-preservation of this gelling material itself and concrete consistency is good, fast solidifying, hard characteristic soon, therefore, this heat-insulation board made by straw, can avoid that traditional warming plate price is high, inflammable, heat insulation effect is poor, the not defect of aspect of constructing easily.In addition, utilize the standby novel heat insulation plate of straw have feature, the humidity of " super insulation " 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 ofly can effectively utilize the method for agricultural crop straw, and utilize stalk to prepare for core to there is some strength, the new green environment protection straw heat-insulating board of heat-insulation and heat-preservation, fire-retardant, mildew-resistant.
The present invention realizes by following technical scheme:
A heat-insulation board made by straw, by the raw material of following weight part, made:

Water 30-50.
Described stalk is common agricultural crop straw, comprises maize straw, wheat stalk, rice straw, broomcorn straw etc., and stalk length is 4-5cm.
Described monovalence dihydrogen phosphate powder is selected from a kind of in potassium primary phosphate, primary ammonium phosphate, SODIUM PHOSPHATE, MONOBASIC, monometallic.
Described metal oxide is selected from a kind of in magnesium oxide, zinc oxide, aluminum oxide, calcium oxide, barium oxide.
Described borate selects a kind of 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: kaolin is placed at 680-720 ℃ and calcines 3-5h, being cooled to normal temperature is placed in the hydrochloric acid soln that concentration is 10-15%, heating in water bath is to 70-80 ℃, insulation 30-40min, filter, with distilled water, residue washing is extremely neutral, dry, then add be equivalent to the sepiolite powder of kaolin weight 5-10%, the asbestos powder of the vermiculite power of 4-6%, 3-5%, the γ-aminopropyl triethoxysilane of the calcium lignin sulphonate of 2-3% and 0.5-1%, speed lapping 20-30min; Finally add the plant ash that is 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, dries, and calcines 1-2h at 960-1120 ℃, is cooled to normal temperature, pulverizes and sieves.
The preparation method of heat-insulation board made by straw, comprises the following steps:
(1) the straw utilization epoxy glue of 4-5cm, jade powder and pearlife are pressed into and have certain size and the good stalk board of mildew resistance in a fixed mold, this stalk board is as the core of novel heat insulation 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 fully mixed, then add water, stir 20-30s, pour that in the Standard Module that stalk board is housed, to carry out top layer coated into, the demoulding after 10-15min, normal temperature maintenance 2h can obtain a kind of heat-insulation board made by straw.
Advantage of the present invention:
The present invention mainly comprises two parts, core layer and coating layer, core layer is mainly that effect by epoxy glue, jade powder and pearlife is first moulding of stalk at random, and there is certain mildew-resistant heat insulation effect, for surface coated novel inorganic gelling 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 has solved the problem of stalk poor efficiency, meet on the other hand the strategic requirement of national development recycling economy, and production method is simple to operation, and cost is low, environmental protection; The heat-insulation board made by straw of preparing 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.
