Description
Technical field
The present invention relates to a kind of manufacture method of flame-retardant board, more particularly, it relates to a kind of perlite flame-retardant board and preparation method thereof.
Background technology
The fire safety problem of wood materials is the important topic in building field always.In recent years, although there is the fire-proof products such as dissimilar PLASTIC LAMINATED, labeled door, but the fire prevention index that these products have does not reach fire protection requirement, can't resolve fireproof practical problem, the a large amount of high-quality timber of some consumptions, what also have is exactly process to material, badly will cause insect pest once process, especially the requirement also not reaching Environmental Safety performance that adhesive wherein has, pollutes the environment.
Owing to inevitably remaining a certain amount of sodium chloride composition in magnesium chloride raw material, should get damp so run into rainy weather at the perlite flame-retardant board one made, causing in the nail of wooden door even has the globule to overflow, after door makes moist, produce torsional deformation, the variable color because making moist of veneer plate face, when door leaf makes veneer also cannot with perlite flame-retardant board and boning, degumming phenomenon is very serious.Also steel plate is caused to get rusty because of getting damp when using as steel door inner core material, even rotten.Due to door leaf inner core in prior art and perlite flame-retardant board premature aging, product weathering is as bean curd shape, and touch can pierce with hand one, general intensity does not all have, and has got damp with not mentionleting alone anti-flammability and resisting.
Summary of the invention
For the deficiency that prior art exists, object one of the present invention be to provide a kind of have fire-retardant, heat insulation, nontoxic, bending and compressive strength is high, perlite flame-retardant board that is not aging and that do not get damp by force in high humidity hydrophobicity.
Object two is to provide a kind of perlite flame-retardant board preparation method.
For achieving the above object, the invention provides following technical scheme: a kind of perlite flame-retardant board, comprise door leaf door core and be filled in the auxiliary packing in door leaf door core, the composition weight proportion of described auxiliary packing is: expanded perlite 10-20kg; Magnesium chloride 26-39kg, magnesia 11-24kg, phosphoric acid solution 200-300 milliliter, French chalk 15-20kg, emulsifier 0. 1-2. Okg, adhesive 51-115kg, copperas solution 4kg, waterproof agent 25-30kg.
The present invention is set to further: the composition weight proportion of described auxiliary packing is: described expanded perlite 15kg, magnesium chloride 32kg, magnesia 18kg, phosphoric acid solution 250 milliliters, French chalk 18kg, emulsifier 1kg, adhesive 88kg, copperas solution 4kg, waterproof agent 28kg.
The present invention is set to further: described copperas solution is formed by 1kg ferrous sulfate and 3kg water Homogeneous phase mixing.
Perlite flame-retardant board is preparation method comprise the following steps:
1), by the composition weight proportion of flame-retardant layer press expanded perlite 15kg, magnesium chloride 32kg, magnesia 18kg, phosphoric acid solution 250 milliliters, French chalk 18kg, emulsifier 1kg, adhesive 88kg, copperas solution 4kg, waterproof agent 28kg gets the raw materials ready;
2) magnesium chloride is made into the liquid of density between 16%-29% by the magnesium chloride 18kg water, got in step 1;
3), the liquid in step 2 is mixed with other raw material in step 1 pour mixer into and stir 5-8 minute form slurry;
4), by slurry pour cold press in door leaf door core into cold pressing with the pressure of 39-41 ton and within 3.5-4.5 hour, make perlite flame-retardant board blank, take out after colding pressing and terminating through or dielectric drying or dry kiln dry; Baking temperature is 75-85 degree Celsius, is 24 hours drying time;
5), the perlite flame-retardant board blank got in step 4), put into mould hot press with the pressure hot pressing 20-30 minute of 42-44 ton, stripping forming after hot pressing terminates;
6), get shaping in step 5) after perlite flame-retardant board blank, by manually with neat saw in length and breadth or sizing saw machine deburring, sanding;
7) quality inspection, packaging and warehousing.
The present invention is set to further: the density of described magnesium chloride is 23%.
The present invention is set to further: described cold press pressure is 40 tons, and the time of colding pressing is 4 hours, and baking temperature is 80 degrees Celsius.
The present invention is set to further: described hot press pressure is 43 tons, hot pressing 25 minutes.
The present invention is set to further: described waterproof agent is waterproofing agent of organosilicon.
The present invention is set to further: described hot press is heated by conduction oil.
By adopting technique scheme, the perlite flame-retardant board that the present invention obtains has fire-retardant, heat insulation, nontoxic, that bending and compressive strength is high, not aging and high humidity hydrophobicity is not got damp advantage.Magnesium chloride is that in the interval range of 16%-29%, perlite flame-retardant board has fire-retardant, heat insulation, hydrophobicity, the advantage such as anti-aging in gravity Baume i.e. its concentration of normal-temperature water solution; Add phosphoric acid solution, French chalk and waterproof agent not only can improve the workability of compound but also effectively can reduce the coefficient of thermal conductivity of perlite flame-retardant board and improve the hydrophobic effect of perlite flame-retardant board; The hydrophily that waterproof agent can also destroy the sodium chloride because existing in magnesium chloride raw material and bring; But along with the increase of phosphoric acid solution, French chalk, waterproof agent addition, the coefficient of thermal conductivity of perlite flame-retardant board and hydrophobicity can be bad trend on the contrary; When density of magnesium chloride be 23%, concentration be phosphoric acid solution 250 milliliters, the French chalk 18kg and waterproof agent 28kg of 5% time, fire-retardant, heat insulation, hydrophobic, the aging-resistant effect of perlite flame-retardant board are optimum.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with specific embodiment, the present invention is described in further detail.
