Abstract
The invention discloses a manufacturing method of an eco-friendly straw self-heat insulation brick. The manufacturing method comprises the following steps of crushing one or more of rice straws, wheat straws, corn straws, sorghum straws and weed straws into short segments, mixing the short segments and gel with stirring according to a certain ratio, carrying out granulation by a granulator to obtain straw granules, drying the straw granules in the sun or by an oven, stirring the dried straw granules, coal ash, slag, broken stone, tailings, building waste, quick lime and cement according to a certain ratio, and carrying out compression molding. The manufacturing method of the eco-friendly straw self-heat insulation brick has the advantages that through use of straw granules, the eco-friendly straw self-heat insulation brick has heat insulation effects; through use of coal ash, slag, broken stone, tailings and building waste, the eco-friendly straw self-heat insulation brick has a high fire retardant coefficient, good strength, a satisfactory dry shrinkage value, good water absorption, satisfactory water content, good freezing resistance, good permeability resistance, good fire prevention, good heat insulation, a satisfactory heat-transfer coefficient, satisfactory thermal inertia factors and good sound insulation; and the manufacturing method guarantees recycling and functional application of straws.
Description
Technical field
The invention belongs to building materials field, be specifically related to a kind of making method of environment-friendly stalk self-insulating brick.
Background technology
Market analysis, between last decade, China will be on the basis of 40,000,000,000 square metres of the existing building total areas, newly-increased 30,000,000,000 square metres floor area of building.China is in the fast-developing period of urbanization; Following 15 years; The annual newly-increased floor area of building of China will reach about 1,800,000,000 to 2,000,000,000 square metres, and under whole Chinese urbanization great development background, real estate is one of most important industry that promotes China's economic certainly.The Ministry of Construction requires: be around big, low in the pollution of the environment, the Remarkable Energy Saving production technology of sharp useless amount, and the sharp useless goods of exploitation high-quality.A medium-sized city, year building amount are about 4,000 ten thousand square metres, and the interior wall coefficient calculations as with 0.7 exterior wall coefficient 1.6 needs 2,800 ten thousand square metres of exterior walls; Even the outer body of wall thick with 240mm calculates, need nearly ten thousand stere, need 6,400 ten thousand square metres of interior walls; The interior body of wall thick with 190mm calculates, and needs more than 1200 ten thousand steres.
Stalk is the general name of ripe farm crop cauline leaf (fringe) part, is often referred to wheat, paddy rice, corn, potato class, oil plant, cotton, sugarcane and other farm crop remainder behind the results seed.The photosynthetic product of farm crop has over half being present in the stalk, and stalk is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter etc., is a kind of multiduty reproducible Biological resources that have.
People are exactly to burn in a large number down on the farm to the most direct impression of stalk processing mode now, and this phenomenon shows particularly outstandingly in east China.After the annual summer harvest, the autumn harvest, the flames lit up the sky in the field, and dense smoke shrouds, and thick smoke almost makes the people suffocate sometimes, and owing to stop transport in the airport that crop straw burning causes, the situation of motorway sealing happens occasionally, loss is difficult to counting.The harm of crop straw burning probably has the following aspects: 1. polluted air environment is detrimental to health.2. initiation fire, the security of the lives and property that threatens the masses.3. cause traffic hazard, influence road traffic and aviation safety.4. destroy Soil structure, cause farmland quality to descend.5. the formed billowing smog of crop straw burning, sheet sheet scorched earth are maximum destruction to a geographic environment image.
Stalk fibre is as a kind of native cellulose fibre, and biological degradability is good, can be used as industrial raw material, like the raw material of pulpwood, lagging material, wrapping material, all kinds of light weight boards.The advantage of functional material of construction such as performance stalk light, insulation, the project of producing self-insulating brick has the cost performance height, and is lucrative, extensive market, utilization is big, utilizes mode simple, advantages such as mode of production robotization.Therefore, producing the A level, not fire the stalk self-insulating brick be pressing for of energy-saving and emission-reduction.
Summary of the invention
Goal of the invention: the invention provides a kind of making method of environment-friendly stalk self-insulating brick, agricultural crop straw is fully used, produce the self-insulating brick of low-carbon (LC), environmental protection.
Technical scheme: the making method of a kind of environment-friendly stalk self-insulating brick of the present invention; Its objective is such realization: a kind of making method of environment-friendly stalk self-insulating brick; After in rice bar, straw, corn stalk, kaoliang stalk, the weeds cane one or more are ground into very short length; Mix stirring by a certain percentage with jelling agent; On tablets press, carry out granulation then, process the straw granule seed, dry or dry the back and be pressed after the stirring by a certain percentage with flyash, slag, rubble, mine tailing, building waste, unslaked lime, cement etc.
The diameter of said straw granule seed is between 2-10mm.
Said gellant material is selected water glass (Na2SiO3) for use, the chemical another name: SODIUM SILICATE (bubble flower alkali).
Beneficial effect: through the environment-friendly stalk self-insulating brick of present method production; Through adding the stalk particle; Make the insulating brick of production have certain heat insulation effect; Make the fire-retardant coefficient of brick body become higher after having added flyash, slag, rubble, mine tailing, building waste again; The stalk self-insulating brick is to be foundation with the light-weight insulating brick structure in performances such as intensity, drying shrinkage value, water-intake rate, water ratio, frost resistance, impermeability, fire prevention, and performance improves more, and the brick body is all having performance preferably aspect heat-proof quality, heat transfer coefficient, heat inertia index, the sound insulation property;
Simultaneously, utilize stalk for resource utilization, functionalization assurance is provided.In process of production, nontoxic, tasteless, no waste gas, no waste, low, the non-wastewater discharge of noise are Green Product.
Through test; The thermal conductivity of rice straw and slip mixtinite is 0.053W/mK, and the thermal conductivity of corn straw and slip mixtinite is 0.051W/mK, and the thermal conductivity of wheat straw stalk and slip mixtinite is 0.068W/mK; Be the excellent insulating material, be superior to energy-conservation 50% index request.
The fire-retardant rank of this self-insulating brick is the A level, meets the notice of The Ministry of Public Security of the People's Republic of China, MOPS's " public affairs disappear [2011] No. 65 " about further clear and definite covil construction heat insulating material for external fire supervision management relevant requirements fully.
Embodiment
Below in conjunction with specific embodiment the present invention is described further:
