Abstract
The invention relates to vitrified microsphere thermal insulation mortar with a self-humidity-control function, which has components as follows: vitrified microsphere, perlite sand, cement, re-dispersible latex powder, high silicon mordenite powder, methyl hydroxyethylcellulose ether, blended fiber, thickener and water reducer. The invention successfully introduces natural zeolite into preparation of the vitrified microsphere thermal insulation mortar, which, on the one hand, improves compactness of the mortar and on the other hand does not reduce thermal insulation performance of the mortar and displays certain hydrophilicity, thus reducing the bleeding of the mortar; when the environmental temperature changes, the mortar is characterized by automatic moisture absorption or release which plays a role of conditioning moisture content of surrounding environment. Therefore, the thermal insulation performance of the mortar is not reduced but the strength is improved. Addition of hydration products in the mortar leads to density of internal structure and improves impermeability and frost resistance of the mortar. At the same time, the zeolite has good acid resistance; and after the natural zeolite is processed into the powder, the dosage of the cement can be replaced which undoubtedly makes contribution to improving the thermal insulation performance.
Description
Technical field
The present invention relates to a kind of thermal insulation mortar for building, refer in particular to and have the thermal insulation mortar of humidity-self-regulation function preferably, be specially the kervit microbead insulated sand slurry that has from the damping function.
Background technology
Sustainable development along with China's fundamental construction, all kinds of buildingss, structures get more and more, and tissue has been built high-quality all kinds of buildings, structures are sign and the embodiments in construction work of China's every profession and trade scientific and technological level, latest technological achievements and level of management.Simultaneously, according to engineering characteristic and environment for use condition, satisfying the various functional requirement of modern architecture to material and structure, and prolong its work-ing life as far as possible, also is the important task that construction industry and engineering technical personnel thereof bear.
Kervit microbead insulated sand slurry belongs to the heat insulating inorganic material of construction, and the heat-insulation system of being made up of this mortar makes indoor temperature and humidity more tame stable when changing season, changes for a short time, has improved the level of comfort of inhabitation significantly.Temperature variation and the humidity condensed of this system by reducing external wall of building reduced the possibility of buildings damage and reduced whole building cost.
Since kervit microbead insulated sand slurry uses, owing to self a lot of good performance, as resistivity against fire, nonstaining property etc., so have good market outlook.But a lot of problems have also appearred in actual use; for example; because the kervit microbead insulated sand slurry water-retentivity is bad; cracking, hollowing phenomenon appear through regular meeting; add chemical water-retentivity material or swelling agent; other performance of kervit microbead insulated sand slurry can be influenced again, even the weather resistance of thermal insulation mortar can be directly influenced.And because the improper operation in the construction operation also can influence the performance of its heat-insulating property, people are studying the approach that improves this situation always, but are improving its various aspect of performances, and always this disappears, and that is long, does not take all factors into consideration the matching between the various performances.
Summary of the invention
The present invention is directed to the problems referred to above that existing kervit microbead insulated sand slurry exists; provide a kind of and can comprehensively improve the various performances of kervit microbead insulated sand slurry; have the thermal insulation mortar of humidity-self-regulation function preferably, promptly have kervit microbead insulated sand slurry from the damping function.
The present invention has adopted following technical scheme to realize above-mentioned purpose: a kind of kervit microbead insulated sand slurry that has from the damping function; its component and proportioning (weight percent) are: glass bead: 30%-50%; pearl rock sand: 5%-15%; cement: 20%-40%; redispersable latex powder: 1%-3%; high silicon mordenite powder (particle diameter≤15 μ m): 15%-30%; methyl hydroxyethylcellulose ether: 0.05%-0.1%; blend fiber: 0.005%-0.1%; thickening material: 0.0002%-0.0003%, water reducer: 0.002%-0.005%.Blend fiber consists of anti-crack fiber and lignin fibre, and its weight percent is: anti-crack fiber 35%-60%, lignin fibre 40%-65%.
The preparation process of above-mentioned blend fiber is as follows: the lignin fibre with aforementioned proportion places whipping device fully to stir earlier, make it be complete expanded shape, anti-crack fiber with aforementioned proportion adds fully stirring in the whipping device again, makes it be complete expanded shape, and blend fiber is promptly manufactured and formed.
The above-mentioned making method that has from the kervit microbead insulated sand slurry of damping function: glass bead, cement, pearl rock sand, the high silicon mordenite powder of aforementioned proportion added in the agitator successively stir; again redispersable latex powder, methyl hydroxyethylcellulose ether, the blend fiber of aforementioned proportion added in the agitator equally successively and stir; the thickening material, the water reducer that add aforementioned proportion then; stir, get final product.When construction, the adding suitable quantity of water stirs (generally speaking, the weight ratio of dry mash and water is 1: 1), stirs to become slurry after 10 minutes, and denseness is controlled at 40-80mm, can use.
The present invention draws on the basis of practice for many years, the present invention has successfully introduced natural zeolite in the making of kervit microbead insulated sand slurry, on the one hand, the pozzolanic activity of zeolite powder is by the content decision of its active silica and activated alumina, and active silica and activated alumina can participate in the aquation and the setting and harden process of gelling material, and the free hydrogen calcium oxide of being separated out in the time of can be with hydrated cementitious reflection, generate hydrated calcium silicate and drated calcium aluminate, promoted the process of hydrated reaction of cement, increase hydrated product, thereby improved the degree of compactness of mortar; On the other hand, because the zeolite intracell has a lot of uniform holes, though, there is passage to link to each other between the hole, but generally speaking, do not reduced the heat-insulating property of mortar, show certain wetting ability, thereby its bleeding is reduced, when ambient moisture changes, have the characteristic of automatic moisture absorption or moisture releasing and the effect of adjusting surrounding environment moisture.Therefore, not only do not reduce its heat-insulating property, improved its intensity on the contrary, the increase of hydrated product in the mortar has caused the internal structure densification, has improved its impermeability and frost resistance.Simultaneously, zeolite has good acid resistance, and after natural zeolite is processed into powder, can replace the consumption of portion water mud, and this also contributes for improving heat-insulating property undoubtedly.
