Abstract

The invention discloses a productive technology method of composite insulation boards, the method takes magnesium oxide and magnesium chloride as major ingredients, takes agricultural and industrial wastes such as sawdust, straws, fly ash and the like as filler, synthesizes phosphate oxide materials with different components and organic compound into a new composite according to a proper proportion, and utilizes advanced magnesite technology for production. The composite insulation board is made of oxide materials containing phosphate, is subject to the process of depolymerization to repolymerization to form phosphatic reticular structure. The method of the invention changes traditional synthesized process, and has the characteristics superior to cement products, such as light, water resistance, fireproofing property, heat insulation, acid resistance, pressure resistance and corrosion resistance and the like. The composite insulation board can be widely use in decorations of hotels, wine shops, factories, bazaars, hospitals, office buildings and home furnishings.

Description

Productive technology method of composite insulation boards
Technical field the present invention relates to concrete or similar material of construction, particularly a kind of productive technology method of composite insulation boards.
Background technology, continuous development along with China's modernization construction, the method that tradition is fired clay solid brick does not more and more meet the requirement in epoch, it engulfs tract every year just as a huge lion is opening one's bloody mouth, about 14.3 billion cubic meters, be equivalent to damage 1,200,000 mu in soil, startling simply to the destruction of ecotope.Simultaneously, China also is coal energy consumption big country, and only coal more than 6,000 ten thousand tons is burnt in this coal consumption every year.
At present, the warming plate made from magnesite board is arranged, but there is the problem of returning halogen, warpage in this warming plate, in the middle of building material industry, use desirable not to the utmost, for addressing this problem, the invention provides a kind of productive technology method of composite insulation boards, in composition, add peculiar properties-correcting agent, what solved traditional magnesite board returns halogen, warpage and anti-aging problem, makes the overall technology index of magnesite product reach advanced international level.The present invention has changed traditional synthesis technique, has the advantages that lightweight, waterproof, fire prevention, heat insulation, resistance to acid, crushing resistance, preservative property etc. all are better than cement products.
Summary of the invention the purpose of this invention is to provide a kind of productive technology method of composite insulation boards.With magnesium oxide, magnesium chloride is major ingredient, with agriculturals such as sawdust, straw, flyash and industrial waste is stopping composition, adopt compacting synthetic method with new properties-correcting agent, the phosphoric acid salt oxide compound material and the organic compound of heterogeneity are synthesized new composition by proper proportion, finally obtain SL environment-friendly energy-saving composite partition wall plate.
The technical solution adopted for the present invention to solve the technical problems is: productive technology method of composite insulation boards is to be major ingredient with magnesium oxide, magnesium chloride, with agriculturals such as sawdust, straw, flyash and industrial waste is stopping composition, adopt compacting synthetic method with new properties-correcting agent, the phosphoric acid salt oxide compound material and the organic compound of heterogeneity are synthesized new composition by proper proportion, utilize advanced magnesite technology to produce.With phosphatic oxide material manufacturing, experienced the process of a depolymerization to repolymerization, form the phosphoric acid salt reticulated structure.Generate the phosphate compounds of indefinite form at ambient temperature.
The composite insulation boards composition:
Proportioning is:
Magnesium oxide (MgO) 40-50%
Magnesium chloride (MgCl 2) 40-50%
Straw or sawdust 10-15%
Magnesium chloride properties-correcting agent 2-5%
Weight is by 100%.
Chemical equation: MgO+MgCl 2+ H 2O=2Mg (OH) Cl
The mechanism effect of each component::
Chlorine China magnesium requires purity 99%, and its characteristics inclusion-free, the product of producing are difficult for producing scum, returning halogen, metamorphism.
Magnesium oxide requires that active purity is more than 85% more than 65%, and the product strength that its characteristics produce is big, and stability is strong, and it is tenderly white to cut color.
Straw or sawdust: mainly play the effect of stopping composition, make the product lightweight, and good springiness.Has waste utilization and emission reduction, the characteristics of energy-conserving and environment-protective.
Magnesium chloride properties-correcting agent: magnesium oxide, magnesium chloride are fully reacted better, and energy controlling reaction time, heating temp make product enhancing, toughness reinforcing, surface halide accumulation resistance.
EPS plate (claiming the benzene plate again) is the abbreviation of expandability polystyrene plate, requires fire-retardant material, and weight is at 12 kilograms/m 2Above.It is a very excellent material of a kind of heat preservation and insulation, therefore mainly plays the effect of insulation in composition board.
Concrete technology:
Feed intake-→ stir-→ two roll-in systems-→ health-→ the skinning side cut-→ pressing EPS plate-→ detect-→ the packing warehouse-in.
The key technical indexes:
Area density, 38kg/m 2
Resistance to impact shock is born the swing of 30kg sandbag drop 0.5m and is impacted flawless 5 times.
The bending resistance failing load, 416kg
Drying shrinkage value, 0.35mm/m 2
Water tolerance is soaked in the water and was not had distortion in 168 hours
Resistance to thermal shocks, no aliquation, flawless
Fire endurance, 〉=1h
Combustionproperty is not fired
Based on the binding characteristic of properties-correcting agent to extraordinary chemical substance.The gordian technique that SL environment-friendly energy-saving composite partition wall plate is adopted is exactly that properties-correcting agent is to phosphoric acid salt and organic selectivity absorption characteristic.Product is determined various proportioning raw materials through mechanism research back, utilizes technologies such as batching, mixing, stirring, powerful mixing to synthesize again, and finished product is the white panel shape, and the plate face is smooth, and heat-insulating property is better than 20 times of common brick, has the effect of resistance to acid, crushing resistance.
The invention has the beneficial effects as follows: the present invention selects distinctive properties-correcting agent, phosphoric acid salt oxide compound material and preparation method, enhanced products effect, what solved traditional magnesite board returns halogen, warpage and anti-aging problem.Because the present invention changed traditional synthesis technique, have the advantages that lightweight, waterproof, fire prevention, heat insulation, resistance to acid, crushing resistance, preservative property etc. all are better than cement products.And have energy-saving and emission-reduction, production technique advanced person, excellent product performance, and low production cost, the every technical indicator area density of composite insulation boards, resistance to impact shock, bending resistance failing load, drying shrinkage value, water tolerance, resistance to thermal shocks etc. all meet national standard, be a kind of material of construction of environment-friendly energy-saving, it has the incomparable advantage of many traditional construction materials.Composite insulation boards has premium properties, and can follow closely, can dig, can saw, can bending moulding, but ease of Use performances such as wallpaper, ceramic tile.Composite insulation boards can be widely used in the finishing of hotel, hotel, factory building, market, hospital, office building and household, and at special dimensions such as aircraft, boats and ships, trains, its Application and Development also has stronger development trend.
