Abstract
The invention relates to plaster mortar for a thermal insulation system of a foam glass building, which consists of dry materials and admixtures. The plaster mortar is characterized in that the dry materials consist of cement, fly ash and fine sand which account for 20 to 25 percent, 15 to 20 percent, and 55 to 60 percent of the total weight of the dry material respectively; and the admixtures consist of dispersible latex powder, hydroxypropyl cellulose ether, lignocellulose ether, polyacrylamide and anti-cracking fiber yarns which account for 0.30 to 0.35 percent, 0.03 to 0.05 percent, 0.02 to 0.03 percent, 0.08 to 0.1 percent, and 0.10 to 0.12 percent of the total weight of the dry material respectively. The plaster mortar has good workability of the admixture and high bonding strength, and is more suitable for the thermal insulation system of the foam glass building in water resistance, operable time and freeze-thaw resistance.
Description
Technical field
The present invention relates to the plastering mortar in a kind of building heat insulation system, relate in particular to a kind of plastering mortar that is used for foam glass building heat insulation system.
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---plastering mortar has obtained using widely especially.
Plastering mortar normally according to the difference of different heat insulation system needs, particularly lagging material, is selected the suitable polymer blend admixture for use, the dry-mixed mortar that is prepared from through mix, homogenizing.Since in the plastering mortar admixture certain the polymkeric substance admixture, so it has good performances such as good bonding, water-fast, freeze-thawing resistant, cracking resistance.
Traditional plastering mortar is divided into two kinds on one-pack type and polycomponent type usually.Single component is meant after mortar manufacturing enterprise is with various ingredients mixing, homogenizing and is packaged into bag that the amount of water by the proportioning regulation adds water at the construction field (site), stirs and can use; The polycomponent mortar is meant by two or more component such as powder component and gel component and constitutes, at the construction field (site) with two or more component by the mixed of proportioning regulation, stir and can use.Wherein therefore the polycomponent mortar all exposes not phenomenon easily at aspects such as transportation, storages owing to have a kind of liquid state that is in its component at least, stores difficulty simultaneously winter.
In the existing building heat preservation system; Thermal insulation layer is main with thermal insulation with molded polystyrene porous plastics (EPS) and extrusion molding polystyrene polyfoam for heat insulation (XPS) mainly, and therefore existing plastering mortar mainly is to develop, produce to the surface property of these two kinds of heat insulating products.Molded polystyrene porous plastics (EPS) and extrusion molding polystyrene polyfoam for heat insulation (XPS) all belong to organic foam plastic, and its surface is a flexible body, and traditional plastering mortar and its formation is organic-inorganic world surface layer and flexible body-just body interfacial layer.And main thermal insulation layer is a multicellular glass in the foam glass building heat insulation system; Multicellular glass belongs to the inorganic body material; Its surface is a stiffener; When traditional plastering mortar is used for the foam glass building heat insulation system, owing to shrinking big, interface, it infiltrates reasons such as more weak, make bad phenomenon such as occurring bonding strength is lower, multicellular glass cracking between plastering mortar and the multicellular glass.
Summary of the invention
Technical problem to be solved by this invention provides the good plastering mortar that is used for foam glass building heat insulation system of a kind of adhesiveproperties.
In order to address the above problem; A kind of plastering mortar that is used for foam glass building heat insulation system of the present invention; Form by siccative and extra material; It is characterized in that: said siccative is made up of cement, flyash and fine sand, and is respectively 20%～25%, 15%～20%, 55%～60% of siccative gross weight; Said extra material by dispersibility latex powder, TSK-Gel G 2000HXL ether, lignocellulose ether, gather third ethernamine and the anti-crack fiber silk is formed, and be respectively 0.30%～0.35%, 0.03%～0.05%, 0.02%～0.03%, 0.08%～0.1%, 0.10%～0.12% of siccative gross weight.
Said cement is the ordinary Portland cement of 32.5 grades of strength grades or 42.5 grades.
Said flyash is the first level flour coal ash.
Said fine sand is a building sand.
Said anti-crack fiber silk is polypropylene fibre or polyacrylonitrile fibre.
A kind ofly prepare the aforesaid method that is used for the plastering mortar of foam glass building heat insulation system, may further comprise the steps:
(1) according to each component of proportioning weighing;
(2) siccative and extra material are poured into stirring in the mixer successively, mixed;
(3) every bag is packaged into bag by 25kg.
The present invention compared with prior art has the following advantages:
1, because the core of dispersibility latex powder is a thermoplastic resin, be dispersed in behind the chance water and form polymeric film in the mortar, constitute snappiness with the solid surface film forming and be connected; Through mechanical build-in type principle, the slip of the hydraulicity is penetrated in the solid material hole simultaneously, solidifies gradually, forms the favorable mechanical build-in with solid material, has good adhesiveproperties between mortar and the multicellular glass thereby make.
2, because TSK-Gel G 2000HXL ether has surfactivity, there are hydrophilic and hydrophobic group in its molecule, emulsification, protective colloid and mutually stability action are arranged; Have HMW, neutral charge and efficient characteristic of condensing and gather third ethernamine; Therefore can make it keep certain water cut in the plastering mortar when being added into; Reduced the velocity of evaporation of moisture effectively, thereby played the water conservation effect, made mixture have good workability.
3, owing to being prone to be dispersed in, lignocellulose forms three-D space structure in the material; And can adsorb the moisture of 6～8 times of deadweights; Therefore make that pulp surface and basic unit's interface hydration reaction are sufficient; When improving workability ability of material, processing property, antiskid and weighing down performance and accelerate speed of application, also improved surface strength, and the cohesive strength of basic unit and the homogeneity of the strength of materials of lagging material; Because lignocellulose has dimensional stability and thermostability, therefore good insulation, cracking resistance effect can in lagging material, have been played simultaneously.
4, anti-crack fiber is to be raw material with the polypropylene, forms through the special process processing and manufacturing, and its outward appearance is the reticulated structure that the mutual commissure of plurality of fibers monofilament forms.After reticulin fiber is put in the mortar; In the mortar whipping process; Horizontal connection between fibre single thread can through mortar self rub and friction is worked and is destroyed and form fibre single thread or reticulated structure fully opens, thereby realize that the polypropylene fibre single thread of One's name is legion plays the effect of anticracking.Since admixture of the present invention reticulin fiber, therefore controlled the tiny crack that factors such as mortar plastic shrinkage, drying shrinkage, temperature variation cause very effectively, and prevented and suppress fissured formation and development.
5, since among the present invention admixture the polymkeric substance adulterating agent, make that the mortar workability is good, bonding strength is high, contractions is little and prolonged operable time, excellent in durability, so can guarantee that plastering mortar and multicellular glass form good bonding interface.
6, through test, the plastering mortar that employing the present invention makes and traditional plastering mortar relatively all are more suitable for the foam glass building heat insulation system on bonding strength, water tolerance, freeze-thawing resistant and operable time.
