Description
Technical field
The present invention relates to a kind of External Walls Heating Insulation, particularly a kind of high-fire-resistance polyurethane thermal insulation board and preparation method thereof.
Background technology
In existing External Walls Heating Insulation, based on rock wool, EPS and XPS plate, phenolic board, also enter the application stage at some regional conventional polyurethanes plates.But above material is due to the performance shortcomings of itself, the development need of economic society can not be met now.
The main component of rock cotton board is Black Warrior slag composition, it is mainly produced is by high smelting furnace, its composition of ores is fully melted, silk is got rid of through high speed centrifugation rod, form rock wool cotton for wadding, high-speed blower makes its cooling forming of jetting, a certain proportion of high-efficiency binder is added in winding-up process, (the production difference of hydrophobic rock cotton board is just, the water-repellancy difference of high-efficiency binder, efficient hydrophobic agent makes an addition in tackiness agent when producing by hydrophobic rock cotton board, the rock cotton board goods of production are made to reach efficient hydrophobic fire line) evenly cloth is cotton by large-scale pendulum equipment, its rock wool collodion is made to be three-dimensional cloth cotton like state, be evenly distributed with on crawler belt.By crawler belt, the rock wool that cloth is good is sent in press device, makes it form the rock cotton board of certain density, by hyperthermia drying stove, make it jet to the high-efficiency binder in rock wool efficiently to act on, bonded by rock wool as a whole, rock cotton board is after hyperthermia drying, paper feeding cooling air outlet goes out, and makes it cool.Through crawler-tread in cutting facility, cutting facility is according to different size, for the corresponding adjustment of cut lengths, adopt longitudinal cut method, make it form length rock cotton board, by parallel motion cast-cutting saw slice, speed is identical with travelling belt advances, adopt transverse cutting, make it form the identical rock cotton board of specification; Parallel overlap after high wind slag, makes it reach packaging thickness, through automatic thermal shrinkage packing machine, rock cotton board entire package, through thermal-shrinkage furnace, makes it pack contraction.
Application rock wool also exists problems in exterior wall heat-preserving system.Rock wool is the one of mineral wool, resource-constrained own, 2010 are added up according to special commission, China rock wool and goods output thereof are 860,000 tons, and wherein for the rock wool quantity not sufficient 100,000 tons of building field, overall completed floor space is less than 300,000 square meters, and rock wool production line production cycle is long, generally a domestic rock wool factory runs the needs time of about 2 years from founding the factory to, and therefore, rock wool Surgery therapy usage quantity cannot meet the requirement of current China building energy conservation far away.Every cubic metre of rock cotton board cost, far above the similar heat preservation construction material in market, considers the huge consumption of China's building energy-saving renovation to lagging material, and therefore, the price of rock wool is unfavorable for that market spread uses equally.To harm: although the fire resistance of rock wool can reach a level, but because it is serious to harm, there is carcinogenic problem, Systems in Certain Developed Countries has carried out strict restriction to the use of rock wool, long-term suction rock wool dirt can cause brochial mucosa inflammation and pulmonary emphysema, the symptoms such as contact dermatitis.From the viewpoint of industry personnel health, strictly use should be limited.Consume energy huge: rock wool produces need carry out remelting, fibrosis to starting material, and this process can produce a large amount of waste water, waste gas, and consumes mass energy, and belong to high energy consumption, high pollutive industries, the overall growth dynamic with China's energy-saving and emission-reduction is not inconsistent.Domestic rock wool technological deficiency: the performance of domestic " rock cotton board " comparatively external product there is a big difference, be mainly manifested in tensile strength and water-intake rate aspect, and these two indexs limit rock making sheet is just applied to the very crucial index of external thermal insulation system.The reason affecting these two indexs is content and the waterproof agent of fiber quality, binding agent, also relevant with production equipment and process condition.Due to the hydrophobic nature of rock wool, it is applied in exterior-wall heat insulation and very easily forms cavity, efflorescence, thus does not reach due heat insulation effect.
Phenolic-aldehyde heat-insulation board be by a certain proportion of resin, whipping agent, tensio-active agent mix becomes A material, then utilize phenolic foam machine that A material and solidifying agent B are expected that entering lamination streamline after high-speed stirring mixes foams for some time, obtains phenol formaldehyde foam after curing molding.
Phenolic resin plate surface strength is very low, is unfavorable for the reliability ensureing that it bonds.And the easy efflorescence of phenolic board etc.Be unfavorable for the splitting resistance of external insulation system.High-rise according to crab-bolt, the globality of phenolic foam board will be destroyed, do not find good solution at present.What is more important domestic phenolic-aldehyde heat-insulation board the coordination of construction technique is still immature, and does not have enough Engineering Projects to prove its safe reliability.
EPS plate is white polyethylene particle, automatically joins in prefoaming machine foam to regulation density according to specification, enters aging bunker ageing more than 8 hours; By in the automatic intake panel forming machine of particle that ageing is good, be called EPS with the sheet material of moulding method foaming.The sheet material of forming is pushed 60 degrees Celsius of steam-cured rooms, discharging in 5 days.Also can outdoor placement 42 days.As required large plate is cut into the sheet material of different thickness again.
EPS plate exists following not enough: Various Seasonal, day and night, the inside and outside change due to the temperature difference of body of wall, and facing tile can receive the impact of three-dimensional thermal stress, can produce stress raisers at finish coat, as at body of wall intersection in length and breadth; Wall or roof and wall junction; The position stress concentration such as in the middle part of big area wall, finish coat cracking causes Tile falling, also has adjacent bricks local compression to be out of shape and causes Tile falling.Meet fiery easy firing, poor thermal insulation property.Heat-proof quality is general, and water-absorbent is also comparatively large and transportation cost is higher, is unfavorable for way far away transport.
XPS plate is that other processes are substantially identical with EPS plate with the shaping white polyethylene particle of extrusion molding.
XPS plate, in completed exterior insulation work, cracking phenomena is commonplace, ftracture and the degree that comes off also comparatively serious.Extruded sheet causes heat-insulation system ftracture and come off and have following reason: do not match with whole system material, incompatible.Verify do not have standard collective drawings to be the fact that industry is all known in international and domestic insulation industry without large-scale weather resistant experiment.Although extruded sheet has good thermal-insulating waterproof, because its intensity high deformation stress is large, smooth surface, hydrophobic, be difficult to the tackiness agent of absorbent binder warming plate, poor with the stickup tack of body of wall.
Also enter the application stage at some regional conventional polyurethanes plates at present, common hard-foam polyurethane warming plate is that catalyst combination polyether glycol and isocyanic ester are mixed in certain proportion in order to amine, is single step reaction.Because conventional polyurethanes is the birth defect of chain-like molecular structure, cause anyway changing amount of flame-retardant agent, its flame retardant properties is all difficult to reach B1 level, and flame retardant properties difference is the subject matter of restriction conventional polyurethanes warming plate application.
