Abstract
The invention relates to a method for producing a fire-proof protein plate. The method comprises the following steps of: resolving protein-containing waste serving as a raw material into a protein peptide solution at a high temperature; adding a stabilizer into the solution to prepare a concrete foaming agent; and preparing a light, energy-saving and fire-proof protein plate by taking early-strength sulphoaluminate cement as a primary material and taking fly ash and sand as auxiliary materials. The produced plate has the advantages of light weight, saving in energy, sound insulation, dampness resistance, fire resistance, and overcoming of the defect of easiness in burning of the conventional energy-saving plate.
Description
Technical field
The present invention relates to a kind of production method of the albumen sheet material of preventing fires, belong to building materials field.
Background technology
Application to energy-conserving plate material is quite extensive on the market at present, and common energy-conserving plate material is of a great variety, wherein relatively common are: rock wool-steel plywood, plant fiber composite board, Rigid foam polyurethane, polystyrene board.
Although energy-conserving plate material at present on the market is of a great variety, advantage is respectively arranged, still have deficiency.Although the composite sheet of filamentary material class has preferably physics characteristic and chemical property, have advantages of that the heat insulation and contamination-free of light weight produces, but its pressure-proof and snap-resistent intensity is little, the water-intake rate aspect does not reach national requirements, can only be as the main material of construction such as movable plank house and steel-structure factory building, perhaps use as non-lbearing wall material, because the complicacy of construction aspect is not suitable as external-wall heat-insulation material.And the energy-conserving plate material that uses chemical foaming agent to produce has advantages of that intensity is high, heat-insulating property is high, can be used as bearing wall, also can be used as external-wall heat-insulation material, but because its whipping agent mainly is chemical composition, can cause to a certain degree impact to environment.Polystyrene material for example, it is that a kind of salvage value is low, is not easy the organic materials of cycling and reutilization, is difficult to degraded under the natural condition.Use polystyrene plates in building operation, can produce can not recycling, environmental pollutant that again can not natural degradation.Its topmost shortcoming is inflammable, and directly there are problem of environmental pollution in mounting suspension member, waste construction material, needs to install boiler etc. in the production process.The polyurethane foam composite sheet is widely used in exterior-wall heat insulation, but it is a kind of inflammable substance, and discharges afterwards a large amount of poisonous prussic acid gases in burning, and in a single day human body sucks, and namely can poison dead.
Albumen waste (sludge of sewage treatment plant, food factories mud) contains abundant protein, pass through the alkaline process forced hydrolysis, remove slag, can prepare protein liquid, this liquid is mixed with raw materials such as xanthan gum, gelatine, sanitass, can produce foam through stirring or the direct mechanical stirring of ventilating, before existing bibliographical information.The peptizer such as this foam and cement are mixed can become foamed concrete, can be widely used in roof insulation, insulation, and exterior wall, interior wall are heat insulation, insulation; Sound insulation, dry etc., realize the preparation of lightweight, energy-conservation, fire prevention green construction material.
Summary of the invention
Technical problem to be solved by this invention provides a kind of fire prevention albumen preparation of plates method.
The present invention at first prepares whipping agent by sludge protein, then take quick hardening sulphoaluminate cement as major ingredient, with flyash and husky as auxiliary material, by mensuration and the analysis to demould time, Absolute Dry Density, water-intake rate and the ultimate compression strength of foamed concrete piece, the reaction parameter that optimization is suitable.
Technical scheme of the present invention is:
(1) will contain albumen mud, unslaked lime and water and mix in the 100:10:50 ratio, then in the suction reactor, and pass into the steam of 0.6～0.7MPa, 140～150 ℃ of lower hydrolysis 1～2 hour;
(2) filtration obtains protein solution, is concentrated into to contain 4 protein 22～25wt%, adds the Sodium Benzoate of protein solution quality 0.1～0.2% as sanitas again, and 3～4% xanthan gum mixes as stablizer, and swelling 12 hours is whipping agent;
(3) with sand: flyash; Quick hardening sulphoaluminate cement: whipping agent: water reducer: water is raw material, by mass parts 800-1000:500-700:200-300:4-7:3-5:80-100 proportioning, stirs;
(4) join in the prefabricated mould, the demoulding after 12-24 hour is transferred to the curing room of relative humidity more than 90%, minimum maintenance 4 days.
The present invention utilizes the foaming character of albumen itself to make it as whipping agent; make protein foam be filled in raw material inside by simple operation technique; form porous material; sheet material light weight, insulation, heat insulation good characteristic have been guaranteed; environment protection and energy-conserving profit waste have been paid attention to; even simultaneously albumen is taken in and also can not produce any side effect in human body, can not produce hazardous and noxious substances from building operation to the process that comes into operation and threaten HUMAN HEALTH.The board lightweight of producing, energy-conservation, not only sound insulation, protection against the tide, and fire prevention have overcome the inflammable shortcoming of existing energy-conserving plate material.
