Problems solved by technology

[0002] Due to its low price and convenient use, cement mortar is currently one of the most commonly used waterproof materials in bathroom, kitchen and other house decoration. However, cement mortar is not water-resistant, needs maintenance, and is prone to cracking and other problems, especially cement. Mortar has poor tolerance to acid and alkali, and it is prone to corrosion for long-term use, making it fall off or lose its waterproofness
[0003] In order to overcome the above problems, the art once tried to mix polymer emulsions, such as styrene-butadiene rubber emulsions, acrylate emulsions, etc., with cement mortar to enhance the performance of cement mortar, but the cost of polymer emulsions is too high, and its promotion and use are restricted by the construction and decoration industry. limit
For this reason, in recent years, this field has also tried to explore the use of asphalt to improve the performance of cement mortar, but in the long-term construction, it was found that the compatibility between ordinary emulsified asphalt materials and cement is relatively poor, resulting in the waterproof quality and construction performance of the product being affected.

Embodiment 1

[0030] The emulsified asphalt raw materials are proportioned according to the following (Table 1) (weight ratio, the same below):

[0031] Table 1 emulsified asphalt formula table (100 parts of emulsified asphalt)

[0032]

[0033] The manufacturing process of emulsified asphalt is as follows:

[0034] (1) Dehydrate the asphalt at 110°C-130°C for 1 hour to 2 hours, then heat it gently to 130°C-160°C, and measure it for later use;

[0035] (2), heat the tap water to 45°C-65°C, and measure it for later use;

[0036] (3) Add the emulsifier and stabilizer to the spare hot water, stir evenly to make an emulsified aqueous solution, control the temperature at 45°C-65°C, and set aside;

[0037] (4) Turn on the emulsifier system, pour the emulsified aqueous solution that meets the temperature requirements into the emulsification, and immediately pour in the hot asphalt that meets the temperature requirements, and the emulsified asphalt that meets the requirements is prepared.
