Thermal insulation mortar for thermal insulation prefabricated part of building wall, and preparation method and equipment

Abstract

The invention discloses thermal insulation mortar for a thermal insulation prefabricated part of a building wall. The thermal insulation mortar is prepared from the following components in parts by weight: 350 parts of Portland cement, 7 parts of polyphenyl granules, 100 parts of ash calcium powder, 520 parts of quartz sand, 20 parts of silica fume, 15 parts of modified seaweed, 15 parts of a concrete admixture and the balance of water. The invention also discloses a preparation method of the thermal insulation mortar, which comprises the following steps: S1, well mixing and stirring Portlandcement, ash calcium powder, quartz sand, silica fume and water; S2, adding polyphenyl granules into a mixture obtained in the S1 and stirring well; and S3, adding modified seaweed into a mixture obtained in the S2 and stirring well to obtain the thermal insulation mortar for a thermal insulation prefabricated part of a building wall. The invention further discloses preparation equipment of the thermal insulation mortar, which can prevent the mortar from splashing out through a feeding tank in the stirring process. The mortar provided by the invention has the advantages of good heat insulationand heat preservation performance, low preparation cost, high viscosity, strong polyphenyl particle wrapping performance, good crack resistance and short hard drying period.

Description

technical field [0001] The invention relates to the field of thermal insulation mortar, in particular to thermal insulation mortar for building wall thermal insulation prefabricated parts, a preparation method and equipment. Background technique [0002] The prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories are processed and manufactured, transported to the construction site, and assembled and installed on site through reliable connection methods. ; [0003] Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., because of the use of standardized design, factory production, assembly construction, information management, and intelligent applications, they are representatives of modern industrial production methods; [0004] In the industrialization of construction, the com...

AI Technical Summary

Problems solved by technology

[0006] In summary, the existing thermal insulation mortar for building wall thermal insulation prefabricated parts has certain defects. It needs to add a large amount of fiber and rubber powder, the preparation cost is high, and the wrapping degree of polyphenylene particles is poor. At the same time, the preparation of building wall The feeding port of the equipment used for thermal insulation mortar for prefabricated body heat preservation cannot be closed. During the mixing process, the mixture is easily splashed through the feeding port.
