Description
Technical field
The present invention relates to a kind of hard polyurethane foams field, particularly relate to a kind of hard polyurethane foams with fire-proof function and preparation method thereof.
Background technology
Hard polyurethane foams is a kind of material with insulation and certain water-proof function, this foam has good insulation, heat insulating function, thermal conductivity factor is extremely low, and waterproof, non-hygroscopic, insulation, sound-absorbing, oil resistant, resistance to chemical attack, light weight, be highly suitable for all kinds new building and existing roof waterproof and insulation, be therefore widely used in the roofing of all types of industries and civil buildings, body of wall, the insulation of flooring, heat insulation, waterproof.
Wherein there is a kind of forming method of polyurethane hard foam to be directly be sprayed on base material by the raw material of liquid, then make the solid shape that its a lot of times of aftershapings that expand become to need.The hard polyurethane foams of spray mo(u)lding is called for short SPF.This solid-state hardness and other physical property can need according to final use and regulate.This is that one applies process very widely on European & American Market, and the application on the market of China is also being popularized gradually.SPF is the king of building trade multifunctional material, its feature be construction simple and convenient, insulation, heat insulation, sealing effectiveness is splendid, is universally acknowledged maximum energy-saving material.Due to the flammable nature of SPF itself, therefore want to use its do building thermal insulation material must on do fire prevention process.Even if added fire retardant in SPF can play certain flame retardant efficiency, but when burnt between long enough and flame temperature enough high time, SPF rigid foam still can be lighted, once be ignited, its ignition temperature can reach more than 2000 degree Celsius.The fire caused due to inner, external wall building heat-insulation material occurs again and again, and the therefore resistance to combustion of polyurethane foam, the problem such as fire-retardant have become problem in the urgent need to address.In addition, when environment for use is severe, SPF rigid foam also needs to do surface treatment that is anticorrosion or weathering.
Patent ZL200610043347.X proposes a kind of polyurethane rigid foam exterior wall thermal-insulation system material, is made up of poly-ammonia Moistureproof primer, polyurethane hard material, interfacial agents, the cracking resistance polymer cement mortar including fiberglass gridding cloth and coating ornamental surface.Be characterized in the phenomenon alleviating external wall outer insulation cracking of wall surface, make the coordination compatible with each other, mutual of each layer of material for external thermal insulation system of external wall reach balance, form an organic whole.Flexiblely deformational stress can be discharged between material layer, reduce the generation of external wall outer insulation cracking of wall surface, and make spray coating polyurethane rigid foam surface smooth, without " puffed rice " shape, uneven and spray foam strong adhesion between layers, overcomes " multi-layer steamed bread " shape delamination.But its cost is high, anticorrosion, fire resistance is poor.
Patent 200810204580.0 proposes a kind of exterior wall exterior heat preservation system for spray coating polyurethane rigid foam, be made up of Moistureproof primer, hard polyurethane foam, boundary mortar, screed-coat, alkaline-resisting grid cloth, decorative mortar, base course wall, polyurethane is directly located at and is scribbled on the base course wall of Moistureproof primer, screed-coat is provided with outside hard polyurethane foam, boundary mortar is provided with between screed-coat and hard polyurethane foam, alkaline-resisting grid cloth is provided with outside screed-coat, decorative mortar is provided with outside alkaline-resisting grid cloth, structure is simple, quick construction, can effectively prevent metope hollowing, Fire resistances is good.But its cost is high, the functional performances such as corrosion-resistant, resistance to cracking, water-impervious are poor.
Patent 201010174224.6 proposes polyurethane rigid foam exterior wall thermal insulation material of a kind of high flame retardant and preparation method thereof.The polyurethane rigid foam exterior wall thermal insulation material of described high flame retardant is made up of component A and B component, wherein, component A is made up of phenolic resins, brominated epoxy resin, phosphorous flame retardant polyether polyol, organic foam stabilizer, catalyst dimethylethanolamine, catalyst dibutyltin dilaurylate, fire retardant and blowing agent one fluorine dichloroethanes, and B component is flame-retardant polyisocyanates curing agent.Present invention also offers the preparation method of above-mentioned external-wall heat-insulation material.The present invention has excellent mechanical property and high flame resistance, overcomes the problem that original Polyurethane Thermal Insulation Building Materials fire retardant performance is conflicting with mechanical property, is applicable to fire-protection rating and requires that the exterior-wall heat insulation of higher buildings is constructed.But the poor performance such as insulation, fire prevention, resistance to combustion.
Summary of the invention
In order to solve the problem, the invention provides a kind of with basic unit firm pasting, corrosion-resistant, anti-flammability is high, the hard polyurethane foams with fire-proof function of long service life and preparation method thereof, comprise foamed bulk, it is characterized in that the upper surface of described foamed bulk is provided with one deck aqueous fire-proof coating.
The parts by weight of described aqueous fire-proof coating consist of: sodium carboxymethylcellulose: 0.1-0.2 part; Water: 12-15 part; Dispersant: 0.3-0.8 part; Defoamer: 0.3-0.8 part; Wetting agent: 0.3-0.8 part; Emulsifying agent: 0.5-0.8; Modification ammonium polyphosphate: 13-15 part; Melamine: 4-7 part; Many pentaerythritol esters: 6-10 part; Zinc aluminate: 4-8 part; Chlorinated paraffin wax: 2-6 part; Titanium dioxide: 4-8 part; Antimony oxide: 2-5 part; Aerosil: 0.4-0.6 part; Expanded graphite: 0.4-0.6 part; Acrylate and vinyl acetate emulsion: 7-10 part; Elastic emulsion: 1-3 part; Film forming agent: 0.4-0.8 part; Thickener: 0.1-0.2 part.
A kind of hard polyurethane foams its preparation method with fire-proof function, it is characterized in that the preparation first preparing aqueous fire-proof coating: by sodium carboxymethylcellulose, water, dispersant, defoamer, wetting agent, emulsifying agent, modification ammonium polyphosphate, melamine, many pentaerythritol esters, zinc aluminate, chlorinated paraffin wax, titanium dioxide, antimony oxide, aerosil, stir after 30 minutes and enter sand mill grinding, detect after fineness reaches 90 μm and stop grinding, under agitation add expanded graphite, acrylate and vinyl acetate emulsion, elastic emulsion, film forming agent, thickener; Then on foamed bulk, spray the aqueous fire-proof coating that a layer thickness is 1-3mm.
Beneficial effect of the present invention is: the present invention according to spraying polyurethane rigid foam fireproof coating exclusively and basic unit's firm pasting, corrosion-resistant, long service life, can on arbitrary surface the substrate performance such as spray mo(u)lding, plan as a whole in conjunction with the specific scope of application and service time the fireproofing technique route having formulated complete set; The present invention has selected a kind of fireproof coating system of a Rotating fields, and direct spraying, on hard polyurethane foam base material, defines this novel spraying polyurethane rigid foam insulation material; Brush one deck fireproof coating on hard polyurethane foam; consider the adhesive property of fireproof coating and hard polyurethane foam; select adhesive force is high, Tg is low elastic emulsion as the resin of fireproof coating; first its good penetrability; together with penetrating into be embedded in foam firmly at foam voids place after drying inside hard polyurethane foam when it; next selects novel N-P system intumescent flame retardent and low-temperature expansion graphite; its water-tolerant, bubbling efficiency are high, heat-proof quality good, have enough resistance to combustion protective effects for soft base material.
