Description
Technical field
The present invention relates to a kind of material of construction, relate in particular to thermal-insulating waterproof material of using on a kind of buildings roof and preparation method thereof, belong to building material field.
Background technology
Defective that adopts at present the lagging material of styrofoam, compact substance styrofoam and thermal insulation mortar (cement mixing granular polystyrene) all to exist technically on the insulation market self can't to overcome and part not fully up to expectations.
Styrofoam is the organic materials that extracts from oil.Styrofoam does not absorb water, and thermal conductivity is little, between 0.029-0.035w/ (m.k), and the temperature influence sensitivity, molecule activity is very active.Heat resisting temperature has only 70 ℃, and when experiment recorded 70 ℃, size changing rate reached 5% after 48 hours.Area, Northeast China outdoor temperature in winter is-45 ℃～-20 ℃, and southern area metope in summer temperature can reach 70 ℃～75 ℃.The styrofoam material is subjected to the acute variation of outside air temperature, just can't change by nature to expand and warpage, and warpage, cracking are unavoidably.Be inevitable so use styrofoam to go wrong, the time length that goes wrong depends on the bonding object, selects for use ether of cellulose and vinylformic acid as cohesive body usually, the mixed cement mortar.These three kinds of materials all have aging time and thermal conductivity.Warpage, the cracking that can not stop styrofoam also can further aggravate the conduction of temperature.The styrofoam construction is gone up and is adopted rivet firmly to go up wall in addition.This constructional method makes styrofoam and metope produce the hollowing distance.The benefit that has distance is to a certain extent to having stoped the inside conduction of temperature.The problem that faces is, in case the styrofoam warpage, hot and cold air-flow just enters the hollowing distance, becomes hot and cold air-flow storing spot, is stored into certain value, and interior wall just becomes pontic, has destroyed indoor isoperibol.The person's character that can not change styrofoam just can not solve warpage, rimose problem, and also to be the Chinese and foreign department scholar be difficult to the problem of capturing so far using on the styrofoam for this.Main raw material vinylbenzene and the butane produced as styrofoam can produce obnoxious flavoures such as a large amount of benzene and carbon monoxide when burning.In case blaze up, the people sucks this kind obnoxious flavour, just loses self-saving ability, finally gets killed.The living environment of China is quite intensive again, in case produce burning, will cause large-area loss of life and personal injury, and the people are lived in unsafe hidden danger.Polyphenyl is the extract in the oil, and the lagging material of China all adopts styrofoam, Imported oil in a large number, and then cause worldwide rise in oil price; The costliness that also can cause the styrofoam material simultaneously conversely.Cause outside a large amount of loss of foreign exchange, be incubated, cause the insulation planned outcome in the whole nation can't smooth implementation, national insulation policy can't be prosecuted to the end, die on the vine as independent dependence styrofoam.In addition, styrofoam belongs to organism, and aging time is short, and 10-20 just begins degraded, and point of ignition is low, vary with temperature and change to expand and shrink, and easy deformation is inflammable, and the burning back discharges obnoxious flavour, and human body is had huge lethality.
Thermal insulation mortar only adds the polyphenyl particle by cement and adds caking agent and mix.The thermal conductivity of cement is high to 1-2w/mk, and the parcel thermal conductivity is the granular polystyrene of 0.042-0.043w/mk, and formed cement and polystyrene mortar thermal conductivity is 0.095-0.098w/mk.Show via Shanghai test center of capital construction commission test result, use the thermal insulation mortar thermal conductivity at 0.1-0.2w/mk on the existing market, do not meet the standard of thermal conductivity below 0.06w/mk of national requirements lagging material.Because there is little conduction in the thermal conductivity height of cement between the cement glue.Exist little conduction to be meant that promptly hot and cold air-flow gathers earlier between the cement glue in distance element, cement can also produce certain barriering effect as the filtering net of current when gathering beginning, gathering of certain hour, body of wall stores hot and cold air and reaches certain value, make interior wall become hot and cold pontic, hot and cold air-flow importing is indoor, and it is indoor to cause outdoor hot and cold flow conductance to be advanced, and has finally destroyed the constant temperature of the interior space.
Existing lagging material can not really reach the insulation requirement.(above Haiti district is an example, and the energy-conservation requirement of secondary reaches 55.6% energy-saving index; The three grades of energy-conservation requirements in Beijing area reach 65%).Along with the standard day by day of the energy-conservation cause of country and perfect, the generally raising of energy-conservation requirement.The energy-conservation requirement regulation of existing Beijing area reaches energy-conservation 65%.Concrete enforcement in the face of this requirement and standard, existing Guan Yong heat preserving exterior wall system, styrofoam, compact substance plate will face the practical problems in technology and the construction: the thermal conductivity of styrofoam is 0.04w/mk, the thermal conductivity of compact substance plate is 0.027-0.029w/mk, though the thermal conductivity of compact substance plate is good, use its Wind-Pressure Resistance value on Highrise buildings just can not be born.The thermal conductivity of cement and polystyrene mortar will reach 65% heat preservation energy-saving index at 0.095-0.098, thickness with thick to 10 or 15cm.This kind thickness will increase the weight of the bearing capacity of body of wall greatly, and the carrying capacity of buildings is strengthened.Also there is proposition " sandwich " method promptly to use wall on the cement and polystyrene mortar therebetween styrofoam of the right and left 3cm.The problem that occurs at first be both sides the cement and polystyrene mortar can not with the firm combination of styrofoam, cause situation about coming off easily.Body of wall is an inorganics again, and the cement and polystyrene mortar is an organism, and inorganic and organic two kinds of materials can not fine combination, in case come off, will cause casualties, and has great potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, the lagging material that provides a kind of new skin roof or vault to use.
