Description
Technical field
The invention belongs to material of construction and product technique field, particularly inorganic foamed light-weight fireproof plate of using of a kind of simatic energy-saving fire proof and preparation method thereof.
Background technology
Along with the raising of people's living standard and quality of life, the fire-fighting of public place requires and for the consideration to the person and material safety, and is more and more higher to the requirement of material of construction fire resistance.For example, door is a requisite part during buildings forms, have the multiple functions such as sealing, safety, insulation, sound insulation and practicality, ornamental characteristics, because the function of opposite house and the requirement of performance constantly promote, therefore fire prevention, antitheft door also arise at the historic moment, and more and more are subject to the extensive attention of the national parties concerned and society.
Although the fire door of initial production also has the situation that adopts fire-retardant material directly to make, because of intensity relatively poor, especially ornamental poor, attractive in appearance not and slack market.Therefore, mostly the fire door that used afterwards is the fire-retardant materials such as filled and process, polyurethane foam material, mineral wool, rock wool, asbestos in metal shell (door-plate), but because its fire-proof and thermal-insulation effect is undesirable, has withdrawed from gradually market.The substitute is integrally-built anti-fire door core board.
At present, domestic PLASTIC LAMINATED manufacturer selects aluminium silicate wool plate, expanded pearlite rock beam, vermiculite board, polyurethane foam board, aluminosulfate cement plate as anti-fire door core board mostly, but because these quality of materials are larger, cause the weight of fire door excessive, the load of door is overweight, reduces work-ing life, produce and use cost too high, the material fire resistance that in addition has is poor, the strength of materials that has is low, damaged heavy, and the complex manufacturing technology that has, price are too high; Even unexpectedly contain the poisonous and harmful goods and materials in sending out material existing, and there are potential threat in human body and environment, the use that has been under an embargo is so the anti-fire door core board of above-mentioned production all has been subject to restriction to a certain degree in promoting the use of.
Summary of the invention
Purpose of the present invention is exactly in order to eliminate defects, provides that a kind of quality is light, intensity is high, scientific formulation, and method is simple, is easy to make, and comprehensive cost is low, magnesium oxide inorganic foamed fireproof board of fire-resistant and other high comprehensive performances and preparation method thereof.
For this reason, the present invention has taked following technical solution:
A kind of magnesium oxide inorganic foamed fireproof board, the ratio of the feed composition of its PLASTIC LAMINATED and weight is:
Magnesium oxide, calcium sulphate hemihydrate, polypropylene fibre ultra-fine fibre, perlite, the proportioning that efficiently improves between auxiliary agent, solution and the water-soluble whipping agent are: 1:0.05:0.0035:0.03:0.00015:0.8:0.083;
Described solution is the mixing solutions of magnesium chloride and sal epsom;
The mixture that described efficient improvement auxiliary agent adopts high efficiency water reducing agent, peregal (permeate agent) OS-15, emulsifier op-10 and trimeric cyanamide to form.
The mole ratio of described Chlorine in Solution magnesium and sal epsom is 5MgH
2O:MgCI
2=1:0.6.
The ratio of high efficiency water reducing agent, peregal (permeate agent) OS-15, emulsifier op-10 and trimeric cyanamide weight is in the described efficient improvement auxiliary agent: 10:2.5:0.8:1.
Described polypropylene fibre ultra-fine fibre diameter is≤1 μ m.
A kind of making method of above-mentioned magnesium oxide inorganic foamed fireproof board, its concrete technology step is:
1, modulates solution in said components and ratio respectively and efficient improvement auxiliary agent is for subsequent use.
2, solid material magnesium oxide, polypropylene fibre ultra-fine fibre and perlite fine powder sent into stirrer be dry mixed after, add successively calcium sulphate hemihydrate, water-soluble whipping agent, the solution that modulates and efficient improvement auxiliary agent, and stir into the magnesia oxychloride cement foamed material.
3, releasing agent is spread upon on the plastic mould that size and dimension is made in accordance with regulations, and the template that coats is carried on the combination grillage.
4, the magnesia oxychloride cement foamed material that stirs is poured onto in the template that combines, makes firm by ramming and flatten.
5, template is transported in the curing kilns together with the good PLASTIC LAMINATED of pouring, maintenance 8～10h afterreaction finishes the demoulding under 35 ℃ of temperature condition.
6, with the smooth hutte of the PLASTIC LAMINATED after the demoulding together, height of embankment≤1.5 m, and avoid direct sunlight, and carry out the sawing polishing behind the 72h, make the finished product magnesium oxide inorganic foamed fireproof board.
Beneficial effect of the present invention is:
Carry out inorganic modified because the present invention's magnesium oxide inorganic foamed fireproof board adopts the mixing solutions of magnesium chloride and sal epsom to add calcium sulphate hemihydrate to magnesium oxychloride cementing material, form inorganic coagulation material, the solid phase of its generation is 5:0.7:6, compare with the chlorine oxygen magnesium gelling material that traditional 5:1:8 coagulation phase generates, become chemical reaction by original physical reaction, chloride ion content is 1% after testing, it is 0.4mm/m that gas is done shrinking percentage, therefore not only greatly improve the intensity of PLASTIC LAMINATED, and can save magnesium chloride 20%; And magnesium oxide inorganic foamed fireproof board of the present invention had both had the hard solidifying property of magnesium oxychloride cementing material, and the drying property of sulfate hemihydrate calcium product is arranged again.
Owing to be added with the efficient improvement auxiliary agent that is formed by high efficiency water reducing agent, peregal (permeate agent) OS-15, emulsifier op-10 and four kinds of mixture of trimeric cyanamide in the magnesium oxide inorganic foamed fireproof board of the present invention, thereby improved the water cement ratio in the magnesium oxychloride cement product reaction, reduce simultaneously the magnesium chloride solution usage quantity, restrain the anti-halogen characteristic in the magnesia oxychloride cement, make temperature equalisation in the magnesia oxychloride cement reaction process.
The magnesium oxide inorganic foamed fireproof board of the present invention science of selecting materials, prescription rationally need not more investments, and manufacture craft is simple, convenient operation, comprehensive cost is low, can reduce cost 20% compared with similar products; Quality is light, and plasticity-is good, but the dry method engraving, and goods unit weight only is 300～330kg/m
3Especially fire performance is good, and its fire endurance can reach 180min under 1200 ℃ of conditions of refractoriness, belongs to the green product of state ministry of public security fire door emphasis Popularization And Development.
