Description
One, technical field
The present invention is specifically related to a kind of novel anti-crack inside heat insulation wall body and construction technology, is mainly used in insulation in the external wall.
Two background technologies
At present, China's building energy consumption has accounted for 35% 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 interior heat preservation technology of body of wall, existing both at home and abroad a large amount of research, and lot of documents is arranged:
Major technique content in these documents is:
1, interior insulation mainly is made up of basic unit, thermal insulation layer, cracking resistance overcoat and skin coat;
2, how the used heat preserving and insulating material of thermal insulation layer is formed with granules of polystyrene, rock wool and thermal insulation plaster;
3, crack-resistant layer is made up of gypsum mortar and fiberglass gridding cloth or nonwoven.
The construction technology of original internal thermal insulated wall system places middle or other positions of anticracking grout, construction technology complexity, the time-consuming material that takes with grid cloth or nonwoven mostly in the construction and use of reality.Efficiency of construction is low simultaneously, and the material consumption is big, can not satisfy the enforcement of current building energy conservation fundamental state policy, is unfavorable for popularizing in an all-round way using.
Three, summary of the invention
Technical problem to be solved by this invention provides a kind of novel anti-crack inside heat insulation wall body and construction technology.Apply materials of the present invention compensation, stress dispersion principle and special construction technology make this body of wall have that thermal and insulating performance is good, little, the high efficient construction of material consumption.
The present invention adopts following technical proposal to realize: a kind of novel anti-crack inside heat insulation wall body, comprise basic unit's body of wall, thermal insulation layer, cracking resistance overcoat, finish coat, the thermal insulation layer is a kind of Multifunction thermal insulation plaster, its component and weight content are: granules of polystyrene B1 part, composite dry powder material A8-13 part, 6～15 parts in water; Wherein the component of composite dry powder material A and weight content are: cement 50～80%, sial hollow glass spheroid material 10～40%, fiber 0.1～5%, air entraining agent 0.005～0.05%, modifier 1～5%, water reducing agent 0.2～1.2%, tackifier 0.5～2%; The cracking resistance overcoat is a kind of cracking resistance gypsum mortar, it consist of 1000 parts in gypsum, 0.3～7 part of water-loss reducer, 1～30 part of retarding agent, 1～2500 part in sand; Finish coat is formed by putty with flexibility, water-fast function and color coating.A kind of construction technology of novel anti-crack inside heat insulation wall body, construction technology is as follows: Multifunction thermal insulation plaster that base treatment → smear is made up of polystyrene foam particles, composite dry powder material and water and levelling → smear cracking resistance gypsum mortar and levelling → finish coat of forming by gypsum, water-loss reducer and retarding agent to handle.
1, base treatment
Processing to basic unit is to prevent that the thermal insulation layer 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 out-of-flatness metope, bright and clean part then should be cut a hole hair and be handled or handle with the polymer cement mortar plucking.
2, thermal insulation layer construction
The thermal insulation layer is respectively composite dry powder material and polystyrene foam particles to be pre-mixed also quota packing, directly mix in proportion at the construction field (site), adding water stirs, its thickness should determine that one-shot forming and levelling are adopted in the construction of thermal insulation plaster according to the coefficient of thermal conductivity and the coefficient of heat accumulation of body of wall in 4cm according to designing requirement.
3, cracking resistance overcoat construction
After the thermal insulation plaster drying (an about week), on the basis of thermal insulation plaster, smear the gypsum anticracking grout.
4, finish coat construction
After the cracking resistance overcoat drying, whitewash have flexibility, the putty of water-fast function and color coating.
Beneficial effect of the present invention:
1, the realization mechanism of thermal and insulating performance
Material:
Adopt granules of polystyrene: because the thermal and insulating performance of polystyrene is good, its coefficient of thermal conductivity is less: λ g=0.041w/ (mk).In this heat preserving and insulating material, dose the granules of polystyrene of some rational gradation compositions, reached the double effects that improves thermal and insulating performance and utilize solid waste.
Technology:
Adopt the closed pore foaming technique: in order to eliminate the heat convection of gas in the hole, adopt miniature pore can reduce radiation heat transfer between the hole wall, thereby further improve the thermal and insulating performance of solid-state material.
Make the uniform miniature closed pore bubble that contains some in the heat preserving and insulating material: because still air is fabulous thermal insulation material, coefficient of thermal conductivity λ g=0.026w/ (mk) in the time of static 0 ℃, coefficient of thermal conductivity than existing various heat preserving and insulating materials is all little, so still air is best thermal insulation material.Make the uniform miniature closed pore bubble that contains some in the heat preserving and insulating material, in solid-state heat preserving and insulating material, dosed best thermal insulation material one still air in fact exactly, can improve the thermal and insulating performance of solid material greatly.
2, the realization of the anti-cracking function of cracking resistance overcoat
Material:
Gypsum itself has good characteristics such as volume stability, high temperature resistant, good permeability, can avoid wall dewfall to occur; In addition, compare with cement, the coefficient of thermal conductivity of gypsum is lower and with insulation layer better compatibility is arranged.
Technology:
Compare with existing interior heat preservation method, simplified construction sequence, improved efficiency, saved material usage, reduced material cost.
To sum up: in whole construction course, selected for use material to have good thermal and insulating performance to guarantee walling system with thermal and insulating performance, meanwhile, by determining good process system, " empty, drum, the split " problem that has solved not only that the heat-preserving heat-insulating wall material often occurs, use this system process to construct, body of wall can satisfy the requirement of building energy conservation.Economically,, can improve efficiency of construction more than 40%, save material cost simultaneously owing to reduced work progress.
