Problems solved by technology

[0002] At present, my country's waterproof coatings are generally divided into water-based waterproof coatings and oil-based waterproof coatings. Water-based waterproof coatings generally include polymer cement waterproof coatings, one-component acrylic waterproof coatings, and modified asphalt waterproof coatings. However, these types of water-based waterproof coatings exist. Some defects limit its application value, such as: polymer waterproof coatings have disadvantages such as easy cracking and poor weather resistance; single-component acrylic waterproof coatings have disadvantages such as low strength and poor water resistance; modified asphalt has problems of poor waterproof and weather resistance; oily waterproof The coatings include polyurethane waterproof coatings and polyurea waterproof coatings. These two types of oily waterproof coatings contain harmful substances when they are prepared or used, and their environmental protection indicators do not meet international requirements.
[0003] In the face of the existing problems of waterproof coatings at this stage, it is still an important challenge for researchers to prepare a water-based coating with excellent water resistance and excellent weather resistance, and the raw materials are environmentally friendly and safe, and the use of non-toxic and harmless
