Description

Hydrophobic concrete-based polyphenylene granule heat-insulating mortar dry powder and using method thereof
Technical field
The present invention relates to a kind of heat-insulating mortar dry powder that is applied to building energy saving field, the especially a kind of heat-insulating mortar dry powder of external thermal insulation system, exterior wall internal insulation system, roof heat insulation system or stair heat-insulation system and using method of this heat-insulating mortar dry powder of being applied to.
Background technology
At present, according to the requirement of national architectural development planning, country will greatly develop the technology of building energy conservation, and building energy conservation will become the developing direction of China's building trade.External wall outer insulation is the important technical of building energy conservation, has become the focus of building energy conservation.External wall outer insulation mainly contains warming plate (mainly containing EPS plate and XPS plate two big classes) and two kinds of forms of concrete-based polyphenylene granule heat-insulating mortar (abbreviation thermal insulation mortar) now: warming plate is not high in present share of market, it is main because the warming plate construction is complicated, comprehensive cost is high and be not suitable for the irregular building part insulation of profile, surface crack is not solved preferably, thereby use is subjected to certain restriction; Thermal insulation mortar has that light weight, thermal conductivity are low, easy construction is not subjected to advantages such as buildings profile control, can overcome many deficiencies of warming plate [1] [2]It has improved the thermal and insulating performance of buildings, has reduced the heating air-conditioner energy consumption, and save energy has improved people's living quality, has favorable economic benefit and social benefit.Thermal insulation mortar utilizes municipal wastess such as waste and old EPS and flyash, turns waste into wealth, and belongs to the environment protecting and power-saving building materials, has very large development space and application prospect [3]
Because body of wall or roof heat insulation market upper layer cracking problem can't obtain basic solution, average external wall surface layer more than 80% all can occur after 2,3 years in various degree and dissimilar crackles.Thermal insulation mortar does not in the market have hydrophobic nature, in case the thermal insulation mortar water content reaches certain degree, its thermal conductivity will raise greatly.The author has also carried out great deal of experimental to the water-intake rate and the relation between the thermal conductivity of thermal insulation mortar.Numerous data are being weighted on average as can be known: when its volume water absorption rate was increased to 5%, 10% and 15% respectively under by the over dry state, its thermal conductivity value had increased by 122%, 198% and 361% respectively.Hence one can see that in order to ensure the thermal and insulating performance later stage stability of thermal insulation mortar, and its water-intake rate index will cause enough attention.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the technical problem of the later stage stability of the thermal and insulating performance of solution concrete-based polyphenylene granule heat-insulating mortar, a kind of concrete-based polyphenylene granule heat-insulating mortar dry powder with high hydrophobic effect is provided, the measure that this heat-insulating mortar dry powder adopts for the hydrophobic rate that improves concrete-based polyphenylene granule heat-insulating mortar is to seek several macromolecular materials and adulterant to carry out compositely coming the thermal insulation mortar of original not hydrophobic nature is carried out modification, and by orthogonal test prescription is optimized processing, improves the hydrophobic rate of concrete-based polyphenylene granule heat-insulating mortar with this.
