Embodiment 1

[0031] The preparation of this permeable two-component polymer cement-based waterproof coating is realized according to the following steps:

[0032] 1. Preparation of liquid material component A material:

[0033] Step (1): Add 40g of acrylic resin with a solid content of 55% and 20g of water in the dispersing tank of the disperser, stir for 5 minutes at 15°C, the mixer speed is 900 rpm, and then add 0.2g of dispersant , and stir for 10 minutes.

[0034] Step (2): Adjust the speed of the disperser to 500 rpm, then add 0.3 g of fungicide and 0.2 g of color paste in sequence, without stopping the stirring during the addition, and stir for 10 minutes after adding.

[0035] Step (3): Adjust the rotational speed of the disperser to 300 rpm, add 0.2 g of silicone oil defoamer, do not stop stirring during the addition, and stir for 10 minutes after adding.

[0036] Material A is stored separately after production.

[0037] 2. Preparation of powder component B material

[0038] S...

Embodiment 2

[0045] Example 2: The differences between this example and Example 1 are shown in Table 1 and Table 2. The mixing device of component A and component B in Example 2 uses a powder-liquid stirring device, and the structure of the powder-liquid stirring device is as follows.

[0046] as attached figure 1 As shown, the powder-liquid stirring device includes a cover body 20 and a tank body 10; a central rotating shaft 30 driven by a gear and a stirring shaft 40 are installed on the cover body 20, and a powder material inlet 61 and a liquid material inlet 60 are arranged on the tank body 10; The body 20 and the tank body 10 are detachably connected by threads.

[0047] The cover body 20 is provided with a fixed ring gear 212 , and the center of the ring gear 212 is provided with a sun gear 21 . The outer periphery of the sun gear 21 meshes with a planetary gear 211 . The lower end of the central gear 21 is fixedly connected to the central shaft 30, and the upper end of the central ...

Embodiment 3

[0058] Embodiment 3: The differences between this embodiment and Embodiment 1 are shown in Table 1 and Table 2.

Abstract

The invention relates to the technical field of building materials, and particularly discloses a high-permeability two-component polymer cement-based waterproof coating which is prepared by the following steps: pouring acrylic resin and water into a dispersion machine, adjusting the rotating speed of the dispersion machine to 900 revolutions per minute, stirring for 5 minutes, then adding a dispersing agent, and stirring for 10 minutes; adjusting the rotating speed of the dispersion machine to 500 revolutions per minute, then sequentially adding the bactericide and the color paste without stopping stirring in the adding process, and then stirring for 10 minutes; adjusting the rotating speed of the dispersion machine to 300 revolutions per minute, adding a silicone oil defoaming agent without stopping stirring in the adding process, and then stirring for 10 minutes; pouring the white Portland cement into a dry powder stirrer, stirring for 5 minutes, adding the quartz sand without stopping stirring in the adding process, and then stirring for 10 minutes; the water reducing agent and the waterproof powder are sequentially added, stirring is not stopped in the adding process, and stirring is conducted for 10 min; propylene glycol and ethylene glycol ether are sequentially added, and stirring is not stopped in the adding process;

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-permeability two-component polymer cement-based waterproof coating. Background technique [0002] For the top floors of high-rise buildings, wall waterproofing has become an increasingly prominent problem, and the quality of waterproofing measures can affect the life of the building. If the waterproof measures are not in place, water infiltration into the wall will accelerate the corrosion of steel bars and carbonization of concrete; the water seepage problem in the building floor will affect the normal life and production of users, and generate high maintenance costs. [0003] The waterproof coating in the prior art produces a hard layer after being applied and dried, which is subjected to pressure and causes the surface layer to rupture. Long-term high-temperature exposure will cause cracks, which are prone to peeling and peeling off, and the waterproof perfor...
