Description
Technical field
The invention belongs to material of construction and product technique field, inorganic foamed light fire-proof plate of the energy-conservation fire prevention usefulness of particularly a kind of simatic 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 necessary part during buildings is formed, have multiple functions such as sealing, safety, insulation, sound insulation and practicality, ornamental characteristics, because the function and the performance demands of opposite house constantly promote, therefore fire prevention, antitheft door also arise at the historic moment, and more and more are subjected to the extensive attention of the national parties concerned and society.
Though 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 and slack market inadequately.Therefore, mostly the fire door of Shi Yonging was fire-retardant materials such as filled and process, polyurethane foam material, mineral wool, rock wool, asbestos in metal shell (door-plate) afterwards, but because its fire-proof and thermal-insulation effect is undesirable, had withdrawed from market gradually.The substitute is integrally-built anti-fire door core board.
At present, domestic PLASTIC LAMINATED manufacturer selects for use 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 bigger, 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 contain the poisonous and harmful goods and materials unexpectedly in sending out material existing, and exist potential to threaten to 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 subjected to restriction to a certain degree in promoting the use of.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of light weight, intensity height in order to eliminate above-mentioned defective, scientific formulation, and method is simple, is easy to make, and comprehensive cost is low, inorganic foamed PLASTIC LAMINATED of magnesium oxide of fire-resistant and other high comprehensive performances and preparation method thereof.
For this reason, the present invention has taked following technical solution:
The inorganic foamed PLASTIC LAMINATED of a kind of magnesium oxide, 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 magnesium chloride and sal epsom is 5MgH in the described solution
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.
The making method of the inorganic foamed PLASTIC LAMINATED of a kind of above-mentioned magnesium oxide, its concrete processing step is:
1, modulates solution in said components and ratio respectively and efficient improvement auxiliary agent is standby.
2, solid material magnesium oxide, polypropylene fibre ultra-fine fibre and perlite fine powder are sent into stirrer and do to be mixed after, add calcium sulphate hemihydrate, water-soluble whipping agent, the solution that modulates and efficient improvement auxiliary agent successively, 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, together with the smooth hutte of the PLASTIC LAMINATED after the demoulding, height of embankment≤1.5 m, and avoid the sunlight direct projection, and carry out the sawing polishing behind the 72h, make the inorganic foamed PLASTIC LAMINATED of finished product magnesium oxide.
Beneficial effect of the present invention is:
Carry out inorganic modified because the inorganic foamed PLASTIC LAMINATED of the present invention's magnesium oxide 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 the inorganic foamed PLASTIC LAMINATED of magnesium oxide of the present invention had both had hard the coagulating 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 of forming by high efficiency water reducing agent, peregal (permeate agent) OS-15, emulsifier op-10 and four kinds of mixture of trimeric cyanamide in the inorganic foamed PLASTIC LAMINATED of magnesium oxide of the present invention, thereby improved the water cement ratio in the magnesium oxychloride cement product reaction, reduce the magnesium chloride solution usage quantity simultaneously, restrain the anti-halogen characteristic in the magnesia oxychloride cement, make temperature equalisation in the magnesia oxychloride cement reaction process.
The inorganic foamed PLASTIC LAMINATED of the magnesium oxide of the present invention science of selecting materials, prescription rationally need not more investments, and manufacture craft is simple, is convenient to operation, and comprehensive cost is low, can reduce cost 20% compared with similar products; Light weight, plasticity-is good, but the dry method engraving, 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 that state ministry of public security fire door emphasis is promoted development.
