Abstract
The invention discloses a process for manufacturing inorganic vitrified microbead insulating mortar and relates to the technical field of heat-insulating material manufacturing. The inorganic vitrified microbead insulating mortar manufactured by the process is manufactured through proportionally weighing and mixing silicate cement, mineral additives, tackifying water retention agent gray powder, chopped-fiber polypropylene chopped fibers, dispersible latex powder and inorganic vitrified microbead particles. The inorganic vitrified microbead insulating mortar manufactured by the process has the characteristics that the compression resistance and durability are relatively good, the rate of shrinkage during coagulation and after hardening is low, the heat insulating effect is good, and the mortar is environment-friendly and the like.
Description
Technical field
The present invention relates to lagging material manufacturing technology field, be specifically related to inorganic kervit microbead insulated sand slurry manufacturing process.
Background technology
China is Energy resources countries in short supply, research and develop novel heat preserving and insulating material and can directly obtain higher economic benefit, be considered to the cycle short, instant effect, the effective way of less investment, along with the proposition of building energy conservation, the development of thermal insulation mortar has been subject to the attention of more and more people, a lot of report was had abroad to the research of thermal insulation mortar, the U.S., the European countries such as Germany have all formulated relevant standard and have made it to implement, heat-insulation system is according to chemical composition divided into organic heat-insulating and inorganic heat preservation: organic heat-insulating mortar is widely used in cold district, from for many years make for, although organic heat-insulating system thermal and insulating performance is good, but there is all drawbacks, such as: the feature of environmental protection is poor, whole system is inflammable and weathering resistance is poor, easily aging, shrinkage cracking etc., inorganic heat preservation system, as a kind of novel lagging material in the market, with the high-performance of its uniqueness, solves these problems.
Summary of the invention
The object of this invention is to provide inorganic kervit microbead insulated sand slurry manufacturing process; the inorganic kervit microbead insulated sand slurry of manufacture of the present invention has good crushing resistance and weather resistance, solidificating period and sclerosis post-shrinkage ratio are low, high insulating effect, and the feature such as environmental protection.
In order to solve the problem existing for background technology, the present invention comprises following steps:
1, six kinds of starting material are selected: (1) inorganic glass bead particle: particle diameter 0.5 ~ 1.5mm, tap density is not more than 250kg/m3, volume water absorption rate≤45%, surface vitreous rate of closed hole >=80%, thermal conductivity≤0.070W/mK, cylindrical compress strength >=200kPa, refractory temperature 1280 ~ 1360 DEG C, (2) strength of cement grade is the ordinary Portland cement of 42.5, (3) mineral additive, (4) sticking enhancing water-loss reducer grey powder, (5) chopped strand polypropylene chopped strand (being called for short PP fiber), 6 ~ 9mm, (6) polymer dispersion powder;
2, silicate cement, mineral additive, sticking enhancing water-loss reducer grey powder, chopped strand polypropylene chopped strand and polymer dispersion powder are measured mixing in proportion, form mixed base;
3, inorganic glass bead particle is mixed with mixed base ratio on demand, the stirring that directly adds water during construction can use, and inorganic glass bead particle can be packed separately, also can pack together with mixed base.
