Description

Thick fireproof mortar phenolic resins plate and the phenolic aldehyde special fireproof mortar of plastering
Technical field
The invention belongs to building field, is that a kind of building exterior wall heat preserving is used for fireproof mortar phenolic resins plate and dedicated mortar specifically, and this phenolic resins plate fireproof mortar thickness is that slurry hardening time is fast about 5mm, and intensity is good.
Background technology
Along with the rapid increase of the whole world to energy demand, can be reduced fast by non-renewable energy resources such as human use's oil, natural gas, coals, and the problem of environmental pollution of following energy resource consumption to bring is on the rise, and energy-saving building technology is taken seriously gradually and promotes.Exterior-wall heat insulation is one of energy-saving building technology, is that a kind of main purpose is to reduce the power-saving technology of building energy loss.Exterior-wall heat insulation is the technology by plinth course outside (comprising cast or building block exterior wall) one or more layers adiabator layer of surface recombination.
The outer wall thermal insulation material can be divided into organic material and inorganic material, and organic material comprises polyphenyl material, polyurathamc, foamed phenolic resin etc., and inorganic material comprises rock wool, foam cement, perlite etc.From the thermal conductivity factor of different insulation materials, the organic insulation material thermal conductivity factor is lower than inorganic heat insulation material, so the organic material heat-insulating property generally is better than inorganic material.Yet organic material is with respect to inorganic material, although heat-insulating property has superiority, fire protecting performance is lower than inorganic heat insulation material.
The phenolic resins plate that exterior-wall heat insulation is used claims again phenolic fireproof insulating plate, is to be formed by the thermosetting phenolic resin foaming, has the characteristics of lightweight, insulation (thermal conductivity factor can be lower than 0.030w/mk).For improving the fire line of phenolic resins plate, the general screed of also smearing the 1mm left and right thickness in phenolic resins plate outside, screed is to be made into by cement, quartz sand, flyash, redispersable latex powder, fiber ether, glass fibre, waterproofing agent, because screed is mainly inorganic material, therefore this fire-protection rating of plastering fireproof mortar phenolic resins plate will be higher than simple phenolic resins.
But, several the generations that cause the building exterior wall heat preserving firing accident of casualties and the heavy losses of property, fire department is had higher requirement to the fire protecting performance of architecture exterior wall insulating materials, suggestion is further brought up to the motar layer thickness of phenolic resins outside about 5mm, namely adopts thick motar.But this has proposed a difficult problem to manufacturing enterprise, this is because if the thickness of compound motar layer is brought up to 5mm outside the phenolic resins, will reach 4-5 days the complete hardening time of this mortar, production cycle is oversize, need simultaneously larger factory building, so production capacity reduces, the economic benefit variation.Although can adopt measures such as increasing early strength agent, minimizing agent and employing quick-hardening cement to reduce hardening time, but also need to be no less than 2 days hardening time, and adopt more quick-hardening cement, although the surface seems the curing that becomes dry, but does not still solidify fully inside, and quick-hardening cement too much can make again mortar strength not reach requirement simultaneously.Although therefore many manufacturing enterprises still can't be reduced to hardening time below 2 days through repeatedly the mortar prescription being adjusted.The another one problem is, after screed reached 5mm, because mortar ratio is important more much higher than phenolic resins, therefore the unit weight of whole plate increased, and the weight increase is larger, the application property variation.
Summary of the invention
The object of the present invention is to provide a kind of thick fireproof mortar phenolic resins plate of plastering, this thick fireproof mortar resin plate of plastering although motar thickness reaches about 5mm, only has 4-5 hour its complete hardening time, and the screed intensity after the curing is good.
Technical scheme of the present invention is: the thick fireproof mortar phenolic resins plate of plastering, and there is thickness to be not less than the motar layer of 4mm in the surface recombination that is the foamed phenolic resin material, the motar layer mainly is to be mixed by mortar major ingredient and sand material small powder to be solidified into,
Consisting of of described mortar major ingredient:
Strength grade is not less than 42.5 portland cement 315-385 weight portion,
Sulphate aluminium cement 315-385 weight portion,
50-100 order sand 90-110 weight portion,
Flyash 90-110 weight portion;
Consisting of of described mixing small powder:
For further reducing mortar unit weight and improving the screed heat insulation effect; also in mortar, be added with glass bead as aglite; per 1 kilogram of redispersable latex powder is allocated 0.35-0.40 kilogram glass bead into; making mortar unit weight is about 110 kilograms/cubic metre, and the excessive mortar strength of addition reduces.
It is 6-10 ten thousand that cellulose ether can adopt viscosity, to take into account intensity and rate of drying.
In described motar layer, also can be compounded with fibrous mesh cloth.
Be compounded with the fibrous mesh cloth reinforcing material in the described foamed phenolic resin.
The present invention also provides the phenolic aldehyde dedicated mortar, and mortar forms as previously mentioned, no longer is repeated in this description at this.
Thick fireproof mortar phenolic resins plate and the dedicated mortar of plastering of the present invention; by the mortar prescription is improved; quote intensity and rate of drying that multiple reactant improves mortar; enable rapid draing moulding in 4-5 hour after phenolic resins plate surface is laminated with; and intensity is better than existing kervit microbead insulated sand slurry, and the phenolic-aldehyde heat-insulation board after being laminated with can reach A level material (8624-1997 country examination criteria).If the adding glass bead, to be laminated with stack pile lighter than unit weight with other mortars, taken into account insulation and two important performances of preventing fires.Also have simultaneously good thixotropy, contract with dry rate is little, and overall performance is stable.Good freeze-thaw resistance and resistance to water.Good cohesive force and shearing force have outstanding cracking resistance resisting wind press capacity.
