[0041] The preparation method of polyrock composite bearing board comprises the following steps:

[0042] Preparation of polyrock fluid: Add the raw materials of polyrock fluid into the reaction kettle, stir and mix evenly at 60-70°C and 1.5-1.7Mpa;

[0043] Preparation of polyrock material: Stir Portland cement, silica fume, carbon fiber, steel fiber, magnesium oxide, magnesium sulfate, straw fiber, and polyrock fluid with a high-speed mixer for 3-5 minutes, and stir evenly; wherein, the speed of high-speed stirring is 600 rpm or more;

[0044] Preparation of poly-rock composite load-bearing board: first pour a layer of poly-rock material with a thickness of 15-30mm into the mold, add foamed cement blocks, and the distance between foamed cement blocks is 20-30mm, and then pour a layer of thickness It is a poly rock material of 15-30mm, and it can be released after standing at 30°C±2°C for 12 hours.

[0045] In order to improve the connection between the poly-rock composite ...

Embodiment 1

[0065] Preparation of polyrock fluid: 9 parts of NNO (sodium methylene bis-naphthalene sulfonate), 0.9 parts of OP-10 (dodecylphenol polyoxyethylene ether), 0.4 parts of calcium formate, 80 parts of water, and 5 parts of water glass , 0.7 parts of water-based silicone waterproofing agent, 6 parts of bauxite, and 4 parts of quartz powder were added to the reaction kettle, and stirred and mixed evenly at 60°C and 1.5Mpa.

[0066] Preparation of inorganic welding agent: 30 parts of Portland cement, 20 parts of magnesium oxide, 15 parts of magnesium sulfate, 30 parts of river sand, 15 parts of quicklime, 8 parts of anhydrous calcium chloride, and 1 part of polyrock fluid are mixed with a high-speed mixer to Stir at a speed of 680 rpm for 3 minutes, stir evenly, and it is ready to use.

Embodiment 2

[0068] Preparation of polyrock fluid: 10 parts of NNO (sodium methylene bis-naphthalene sulfonate), 1.0 part of OP-10 (dodecylphenol polyoxyethylene ether), 0.5 part of calcium formate, 100 parts of water, and 6 parts of water glass , 0.8 parts of water-based silicone waterproofing agent, 7 parts of bauxite, and 5 parts of quartz powder were added to the reaction kettle, and stirred and mixed evenly at 65°C and 1.6Mpa.

[0069] Prepare inorganic welding agent: 35 parts of Portland cement, 25 parts of magnesium oxide, 20 parts of magnesium sulfate, 35 parts of river sand, 20 parts of quicklime, 9 parts of anhydrous calcium chloride, 1.5 parts of polyrock fluid, and use a high-speed mixer at 680 Stir at a speed of rpm for 4 minutes, stir evenly, and then use it.

Abstract

The invention relates to the field of inorganic building materials, and discloses an inorganic welding agent, a preparation method and a prefabricated building connection method. The inorganic welding agent is prepared from, by weight, 30-40 parts of Portland cement, 20-30 parts of magnesium oxide, 15-25 parts of magnesium sulfate, 30-40 parts of river sand, 15-25 parts of quick lime, 8-10 parts of anhydrous calcium chloride and 1-2 parts of polyrock liquid. The inorganic welding agent provided by the invention can be well bonded with a polyrock composite bearing plate, cracks are not generated after final setting is performed for 30 days, and the inorganic welding agent is high in drying speed and meets the construction requirements of prefabricated buildings.

Description

technical field [0001] The application relates to the field of inorganic building materials, and mainly relates to an inorganic welding agent, a preparation method and a connection method for prefabricated buildings. Background technique [0002] 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 (such as floors, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. [0003] There are two existing connection methods for prefabricated buildings, one is dry connection and the other is wet connection. Dry connection is generally welding connection, bolt connection, rivet connection, etc. Wet connection is mainly on-site The way concrete is poured. [0004] The applicant provided a new load-bearing wall for prefabr...
