Description
Technical field
The present invention relates to building material technical field, particularly a kind of bonding mortar for phenolic-aldehyde heat-insulation board.
Background technology
At present, along with the increasing of national building energy conservation dynamics, the application of External Thermal Insulation Technology for External also strengthens thereupon, and its important integral part-bonding mortar is widely used especially.
Bonding mortar is a kind of difference according to different heat insulation system need, particularly lagging material, selects suitable polymeric additives, through the dry-mixed mortar that mixing, homogenizing are prepared from.Due to the polymeric additives that admixture in bonding mortar is certain, therefore it has the good performance such as bonding, water-fast.
Traditional adhesive mortar is divided into one-pack type and two kinds, polycomponent type usually, and single component refers to that mortar manufacturing enterprise is packaged into bag by after various ingredients mixing, homogenizing, and the amount of water specified by proportioning at the construction field (site) adds water, and stirs and can use; Polycomponent mortar refers to and is made up of two or more the component such as powder component and gel component, at the construction field (site) by the ratio mixing that two or more component specifies in proportioning, stirs and can use.Wherein polycomponent mortar is a kind of liquid owing to having at least in its component, therefore, in transport, storage etc., all exposes not phenomenon easily, simultaneously storage in winter difficulty.
In existing heat insulation system, phenolic-aldehyde heat-insulation board is conventional warming plate.Phenolic-aldehyde heat-insulation board is the heat preservation plate material be made up of phenol formaldehyde foam, phenol formaldehyde foam adds by resol the closed pore rigid foam that whipping agent, solidifying agent and other auxiliary agent make, it has good thermal and insulating performance, and be a kind ofly novelly not fire, the lagging material of low cigarette, its fire-protection rating reaches A level, fundamentally stops the possibility of lagging material presence of fire.Wherein, phenol formaldehyde foam belongs to organic foam plastic, and its surface is flexible body, traditional bonding mortar and its formation organic-inorganic world surface layer and flexible body, stiffener interfacial layer.During the bonding phenolic-aldehyde heat-insulation board of traditional bonding mortar, easy to crack, bonding insecure.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of bonding mortar for phenolic-aldehyde heat-insulation board, easy to crack and bonding unstable problem when solving the bonding phenolic-aldehyde heat-insulation board of existing bonding mortar.
Technical scheme of the present invention is such realization:
A kind of bonding mortar for phenolic-aldehyde heat-insulation board, it is made up of the component of following weight parts: general purpose portland cement 350 ~ 450 weight part, flyash 50 ~ 100 weight part, quartz sand 500 ~ 600 weight part, redispersable latex powder 10 ~ 20 weight part, lignocellulose 0.5 ~ 1.5 weight part, hydrophober 1 ~ 3 weight part, poly-third fiber 0.5 ~ 1.5 weight part.
Wherein, preferably, a kind of bonding mortar for phenolic-aldehyde heat-insulation board, it is made up of the component of following weight parts: general purpose portland cement 350 ~ 400 weight part, flyash 60 ~ 90 weight part, quartz sand 500 ~ 550 weight part, redispersable latex powder 10 ~ 15 weight part, lignocellulose 0.8 ~ 1.2 weight part, hydrophober 1 ~ 3 weight part, poly-third fiber 0.5 ~ 1.5 weight part.
Wherein, preferably, a kind of bonding mortar for phenolic-aldehyde heat-insulation board, it is made up of the component of following weight parts: general purpose portland cement 380 weight part, flyash 70 weight part, quartz sand 532 weight part, redispersable latex powder 14 weight part, lignocellulose 1 weight part, hydrophober 2 weight part, poly-third fiber 1 weight part.
Wherein, preferably, described quartz sand is the dry quartz sands of 70 ~ 140 objects.
Wherein, preferably, described flyash is second class powered coal ash.
Bonding mortar preparation method of the present invention is as follows: accurately take each raw material, stir and form.For the dry powder compound of single-component.Blunge is needed during use, per ton with reference to amount of water 300kg.
The thin layer that bonding mortar of the present invention is used as Energy Conservation Project in Construction phenolic-aldehyde heat-insulation board is wiped one's face.During for external wall outer insulation, generally support the use alkali resistant glass fibre open weave cloth.
Beneficial effect of the present invention:
1. the silicate cement that the present invention is used as gelling material, fast solidifying, early strength and later strength high, frost resistance, anti-carbonation properties, wear resistance is better than other cement.
2. the SiO of solubility in raw material powder coal ash of the present invention
2, Al
2o
3isoreactivity composition when there being water to exist, can with Ca (OH)
2water generation reaction Calucium Silicate powder (C-S-H) and drated calcium aluminate (C-A-H), consume Ca
2+, reduce Ca
2+separate out surface probability.In addition, fly ash form effect improves workability, the homogeneity of mortar, enhances mobility, water-retentivity simultaneously, and mixing-water requirement is reduced, and reduces the rear mortar porosity of sclerosis.And flyash of the present invention and silicate cement react the intensity that can increase cement.
3. the redispersable latex powder that the present invention is used is spray-dired polymer dry powder, it can significantly improve inorganic mineral material adhesiveproperties, improve snappiness, hydrophobic nature, the weathering resistance of polymer mortar, clear up body of wall self stress-strain, thus greatly improve and ensured polymer mortar opposing and cleared up the circulation of self drying shrinkage stress-strain and the external world hot rain and freeze-thaw cycle causes the ability of warm and humid stress-strain, avoid the cracking of mortar synthem and come off.
4. the lignocellulose that the present invention is used is that natural timber processes through chemical treatment, mechanical process the organic wadding fibrous material obtained, nontoxic, tasteless, pollution-free, "dead", there is good effect to preventing coating cracking, raising water-retentivity, the stability improving production and the workability of construction, the sticking power etc. of effects on surface of gaining in strength, strengthen.
5. the hydrophober that the present invention is used can change material molecule structure, the permeability of system can be ensured again under the prerequisite making water molecules invade, when rainwater impacts on it, water droplet can trickle by nature, moisture is stoped to invade, building surface dust can also be washed away totally simultaneously, in indoor use procedure or the body of wall water saturation alluvial caused of trying to meet the deadline for the project progressively be discharged into outdoor by exterior trim surface layer, avoid the building that water causes to destroy, thus play make interior wall protection against the tide, mildew-resistant, exterior wall is clean and prevent the effect such as weathering, minimizing strain.
6. the present invention's polypropylene fibre used can reduce the shrinkage strain of cement matrix, improves its splitting resistance.
7. act synergistically between each composition of the present invention, form stereoscopic protective system, easy to crack and bonding unstable problem when fundamentally solving the bonding phenolic-aldehyde heat-insulation board of bonding mortar.Use bonding mortar of the present invention, firmly, convenient and quick construction, can reduce labour intensity, improve operating environment bonding, with low cost controlled.
