Problems solved by technology

[0006] CN102839581A The asphalt thin layer used in the high-viscosity modified asphalt thin layer pavement of assembled coil (plate) material structure discloses the technology of integrating asphalt thin layer into factory production and assembly construction; CN110256994A and CN108529957A are high-viscosity special Mortar technology has small thermal deformation and is not easy to crack, but it will still crack under the influence of long-term thermal expansion and contraction, especially at the joints and corners of components where the stress is relatively concentrated, cracking is difficult to avoid. Although the asphalt thin layer It is very effective in overcoming cracking, but the bonding between the asphalt layer and the high-viscosity mortar is poor, and the asphalt material is not easy to disperse, and is easy to gather and flow freely, which is a headache for technicians in the industry

Embodiment 1

[0048] Embodiment 1, manufacture of prefabricated building components: Pour the high-viscosity special mortar of the present application into the mold of prefabricated building components, and use the vibrating rod to vibrate those modified quartz that are well combined with asphalt-containing glass fibers and quartz sand The sand will not migrate and accumulate. If the method of masterbatch is not used, the same amount of glass fiber and asphalt is directly added to the quartz sand and stirred. No matter how uniform the mixing is, the process of shaking will inevitably lead to the migration and accumulation of glass fiber and asphalt, forming A large number of weak links seriously attenuate the life of components. After shaking, use hydraulic presses, heavy boards, road rollers, scrapers and other tools to flatten the high-viscosity special mortar of this application, fit the mold well, and let it stand for 1-5 hours It can be removed from the mold without conventional standin...

Embodiment 2

[0049] Embodiment 2, assembly of prefabricated building components: when assembling buildings, first spray or scrape an appropriate amount of high-viscosity special mortar on the junction of prefabricated building components, then perform assembly and compaction, and finally scrape off excess High-viscosity special mortar can improve the bonding performance of components, form a smooth whole, and improve earthquake resistance and crack resistance.

Embodiment 3

[0050] Example 3, maintenance and remediation after partial damage of the prefabricated building: due to various reasons, the prefabricated building is partially damaged, and the conventional remedial scheme has poor combination and poor material compatibility, so it cannot be tightly combined, and the damage will continue to be repaired in the future, and the damage will be aggravated For repairing with the high-viscosity special mortar of this application, it is necessary to cut and chisel out a certain material repair accommodation space, then fill in the high-viscosity special mortar, press it with a wooden board or metal board coated with a thin layer of vegetable oil and let it stand for more than 6 hours , and then demolded, due to the interaction between the microscopic asphalt-containing glass fiber modified quartz sand and the combination of the colloidal components in the high-viscosity special mortar, the repaired part is closely combined with the original component ...

Abstract

The invention discloses high-viscosity special mortar for prefabricated buildings and a preparation method of the high-viscosity special mortar, wherein the high-viscosity special mortar comprises a biogel modified aqueous acrylic acid solution, a high-adhesion silane modified polyether sealant, asphalt and glass fibers. The invention also provides the preparation method of the high-viscosity special mortar. The preparation method of the high-viscosity special mortar comprises a high-viscosity special mortar main material preparation method, a high-viscosity special mortar auxiliary material preparation method and a special mortar blending process. According to the method, large-batch rapid production of the fabricated building components can be met. The mortar has high viscosity and good shaping property after molding, is convenient for compression molding and rapid demolding, and greatly improves the molding efficiency; especially, when components are assembled and prevented from deforming, cracking and being repaired after being damaged, construction is convenient, connectivity is good, repairing efficiency is high, the service life is long, and defects are few.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-viscosity special mortar for prefabricated buildings and a preparation method thereof. Background technique [0002] A building assembled on site by prefabricated components is called a prefabricated building. According to the form and construction method of prefabricated components, it is divided into five types: block building, plate building, box building, skeleton plate building and rising plate building; as long as the prefabricated building components are transported to the construction site, the building can be built. Like machine production, it is manufactured in batches and complete sets. The types of components mainly include: exterior wall panels, interior wall panels, laminated panels, balconies, air-conditioning panels, stairs, prefabricated beams, prefabricated columns, etc. Standardization of design and informationization of management, The more standard t...
