Description

Wall heat-insulating boundary mortar
One, technical field
The present invention relates to a kind of wall heat-insulating boundary mortar, be mainly used in architectural exterior-protecting construction wall body outer wall outer heat insulation system.
Two, background technology
At present, China's building energy consumption has accounted for 27% of national total energy consumption, and, along with constant development of economy, improving constantly of living standards of the people, the proportion of building energy consumption will further increase, and the building energy consumption of present American-European developed country has reached 40% of whole society's total energy consumption.Therefore, save building energy consumption, promotion and implementation building energy conservation work meaning is great, and is imperative.The thermal isolation technique of body of wall; existing a large amount of research both at home and abroad; wherein the polystyrene granule insulating mortar external insulation system is the wider a kind of external wall heat insulation system of present China use range; have the reducing energy consumption that not only is adapted to the energy-saving protective of new building but also is adapted to existing building, simultaneously energy-conservation profit useless, do not produce outstanding advantage such as heat bridge effect.Generally, the polystyrene granule insulating mortar external insulation system is formed by interfacial layer, thermal insulation layer, cracking resistance protective layer and finish coat, and interfacial layer is thermal insulation layer and body of wall basic unit middle transitional layer, is the key structure that prevents that lagging material from producing hollowing, coming off.About the interfacial layer material, the research of boundary mortar, at present existing comparatively sophisticated research, and the lot of documents report is arranged, main in these documents
Technology contents is:
1. heat-insulation and heat-preservation material body of wall mainly is made up of binding agent, insulating, crack-resistant layer and finish coat; Processing to basic unit is to prevent that insulating from producing one of requisite measure of " empty, drum " phenomenon.Base treatment technology is generally Surface Physical and handles and chemical treatment, the situation of apparent surface, physical treatment is partly carried out in loosening, the weathering of reply surface of wall, can use the ordinary mortar levelling to the unfairness metope, bright and clean part then should be cut a hole hair and be handled or handle with the polymer cement mortar plucking.
2. boundary mortar is to add the interfacial agents that a certain amount of auxiliary agent is mixed with in the high molecular polymer, during use and cement and the medium sand mortar evenly made of mix by a certain percentage.Wherein interfacial agents is to be main base-material with emulsion, is a kind of high-molecular cement system, and this product has certain perviousness, with abundant infiltration base material, prevents hollowing, increases the adhesive property interface;
3. the ratio of boundary mortar: interfacial agents: fine sand (medium sand): cement was by 1: 1: 1 weight ratio.
Relatively more existing boundary mortar can be found: the preparation of boundary mortar almost all is polymer (or polymkeric substance) cement system at present, macromolecular material mainly act as water conservation, thickening power to cement system, wherein the macromolecular material consumption is more than 30%, a large amount of introducings of macromolecular material, not only caused with high costs, and its time of coagulation etc. be difficult to control, caused great inconvenience for site operation.
Three, summary of the invention
Technical problem to be solved by this invention provides the boundary mortar and the corresponding construction technology thereof of a kind of low cost, easy construction.The present invention uses self water-keeping thickening characteristic of various materials, has strengthened the combination of lagging material and body of wall basic unit, has that adhesive property is good, operating efficiency is high and advantage such as with low cost.
The present invention adopts following technical proposal to realize: a kind of wall heat-insulating boundary mortar, mainly to form by cement, sand and admixture, and the ratio of each component is cement: sand: the weight ratio of admixture 1: 1: 0.1~0.5.Wherein cement is 42.5 ordinary Portland cements, and sand is medium sand or fine sand, and admixture is by retardation setting type cement water reducing agent, water-holding agent and fibrous, and the basic ratio of each component is: water reducer: water-holding agent: fibre weight is than (1: 1~1.5: 2~4); Other admixture that the retardation setting type cement water reducing agent can be Sunmorl N 60S or has a similar functions combines, water-holding agent is one or more in methylcellulose gum (ether), carboxymethyl cellulose (ether), carboxylic propyl methocel (ether) or the basic Mierocrystalline cellulose of carboxylic (ether), fiber is a blend fiber, the composition length of blend fiber is that 3mm mixes with xylon or the man-made fiber of 6mm, and its ratio is 1: 2~4.It uses technology to be: after each component of admixture is proportionally prepared, directly add in cement, the sand at the scene.
The acting as of each component among the present invention: cement and sand provide basic mechanical strength, and admixture is used to improve the serviceability and the anti-shrinkage strain performance of cracking resistance of cement and sand.Wherein particularly, water reducer, water-holding agent are used to improve its construction working performance, prevent because the matrix of body of wall absorbs water in a large number, cause hydrated cementitious not enough and produce empty, drum, come off, and blend fiber mix the contraction that can reduce mortar, prevent to produce inconsistent distortion between itself and body of wall and the lagging material, reduce the possibility that it comes off.
Beneficial effect of the present invention is: the surface treatment of adopting proportioning provided by the present invention to carry out body of wall has not only solved " empty, the drum " problem that easily produces in the insulation construction, and has reduced material cost, has improved operating efficiency.As: 1. after adopting concrete admixture commonly used to make up, its consumption only is 0.5~2.5% of the total consumption of material, with existing interfacial agents: fine sand (medium sand): cement (weight ratio 1: 1: 1) is compared, and its admixture consumption has descended more than 30% by 33.3%; 2. owing to admixture in the body series is the combination of several admixtures, therefore, can be when satisfying its mechanical property by resize ratio, its serviceability of better controlled: 3. because body series admixture consumption is less, its material Financial cost can reduce more than 30%; 4. owing to can reduce manpower more than 40% the time of coagulation of the whole system of may command.
