Problems solved by technology

[0009] As mentioned in the background technology section, the acrylic, styrene-acrylic and other emulsions used in the existing water-based base treatment agents are prone to water channeling when exposed to water, causing a large amount of water vapor to exist between the base and the coil, resulting in poor bonding performance The problem

Embodiment 1

[0063] This example is used to illustrate that the water-based base treatment agent composition according to the present invention is prepared according to the formula and process parameters in Table 1, and the water-based base treatment agent is prepared according to the following method.

[0064] The method for preparing the water-based base treatment agent comprises the following steps:

[0065] (1) Stir the water and the thickener at 150 rpm for 8 minutes at normal temperature to obtain the first mixture;

[0066] (2) Stir the first mixture obtained above and the pH regulator at 150 rpm for 8 minutes at normal temperature to obtain the second mixture;

[0067] (3) at normal temperature, the second mixture obtained above was stirred with SBS emulsion and defoamer at 800rpm for 15min to obtain the third mixture;

[0068] (4) At room temperature, the third mixture obtained above and the emulsified asphalt were stirred at 800 rpm for 15 minutes to obtain the water-based base ...

Embodiment 5

[0071] In this example, a water-based base treatment agent is prepared using a formula and method similar to that of Example 1, except that in the SBS emulsion, the molar ratio of the amount of SBS to the acrylate is 1:5, see the table for details 1.

Embodiment 6

[0073] This example adopts the formula and method similar to Example 1 to prepare the water-based base treatment agent, the difference is: in the SBS emulsion, the molar ratio of the SBS to the acrylate is 1:0.2, see the table for details 1.

Abstract

The invention relates to the technical field of building waterproofing, and discloses a water-based base layer treating agent composition, a water-based base layer treating agent and a preparation method and application of the water-based base layer treating agent. The water-based base layer treating agent composition contains two or more of emulsified asphalt, water, an SBS emulsion, a pH regulator, a defoaming agent and a thickening agent which are stored in a mixed mode or stored independently, wherein the emulsified asphalt is anionic emulsified asphalt, and the SBS emulsion is an interpenetrating polymer network emulsion of SBS and acrylate. The emulsified asphalt, the SBS emulsion, the thickening agent, the defoaming agent and the pH regulator are synergistically compounded, the formed water-based base layer treating agent can be effectively integrated with the asphalt waterproof coiled material, the bonding strength between the asphalt waterproof coiled material and the water-based base layer treating agent is enhanced, the current standard requirements can be met after long-term water soaking, and the water channeling possibility is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a water-based base treatment agent composition, a water-based base treatment agent and a preparation method and application thereof. Background technique [0002] Building waterproofing is an effective means to prolong the life of a building. Building waterproofing is divided into material waterproofing and structural waterproofing. Material waterproofing is to rely on building materials to block the passage of water to achieve waterproofing or enhance the ability to resist leakage, such as coiled materials Waterproofing, coating waterproofing, rigidity of concrete and cement mortar, and clay and lime soil waterproofing, etc. Among them, asphalt membrane waterproofing is the most important material waterproofing, but asphalt membranes are directly laid on the base layer, which will easily lead to weak bonding between the membrane and the base layer , and due to the...
