——Graduation thesis "Research on New Waterproof Coatings" Literature Retrieval Report
Project Analysis
Waterproof Coatings It can be divided into many types according to its use. My graduation thesis mainly studies the most widely used building waterproof coating.
Building waterproof coating is composed of polymer materials, asphalt, polymer modified asphalt, and inorganic materials. It is made by mixing appropriate amounts of additives, modified materials, filling materials, etc. into the main body. Compared with waterproof membranes, waterproof coatings are simple and convenient to construct, are suitable for base surfaces of any shape, and can form a dense and seamless coating. Membrane, therefore, waterproof coatings have been widely used in various waterproofing projects and have achieved rapid development. The research on this topic is mainly divided into three stages.

2. Background information
2.1 Concept of building waterproof coating
Building waterproofing material is an important part of building materials and is functional The main purpose of materials, buildings and structures to use waterproof materials is to prevent moisture, seepage and leakage.
Building waterproof coating, (referred to as waterproof coating) is a kind of building waterproof material. The coating Alone or combined with carcass reinforcement materials, layered brushing or spraying on the surface of the base layer that needs waterproofing treatment can form a continuous, seamless and integral coating waterproof layer with a certain thickness under normal temperature conditions, thus meeting the needs of industrial applications. It is related to the waterproofing and impermeability requirements of roofs, basements, bathrooms and exterior walls of civil buildings. Waterproof coatings are generally made of asphalt, synthetic polymers, synthetic polymers and asphalt, synthetic polymers and cement or inorganic composite materials Solvent-based, water-emulsion-based or reaction-based, which is a viscous liquid or liquefiable solid powder that has no fixed shape at room temperature and is processed by adding an appropriate amount of pigments, additives, solvents, etc. as the main film-forming substances. Composite materials containing polymer synthetic materials, its development profile can be found in the search results (1).
2.3 Current problems that still need to be solved in the research and application of waterproof coatings
(1 ) Most waterproof coatings are solvent-based, which pollutes the environment greatly, while the quality of water-emulsion polymer-modified waterproof coatings is not stable enough.
(2) The mechanical properties of some polymer waterproof coatings are The waterproof performance and durability are not very ideal.
(3) In order to reduce costs, some manufacturers cut corners and pass off inferior products, resulting in a large number of substandard products flowing into the market.
3. Problems solved
(1) Retrieve the background knowledge and related basic knowledge of the preparation of building waterproof coatings.
(2) Retrieve the research status of domestic building waterproof coatings Retrieve building waterproofing Background knowledge of coating preparation.
(3) Retrieve the current application status of architectural waterproof coatings.
(4) Understand the current problems that urgently need to be solved in architectural waterproof coatings.

6. Summary
Although we are in the Department of Chemistry, we are still far away from waterproof coatings in the chemical industry. I chose this topic from my own life experience. During my internship, the school happened to be painting, and my classmates were really intolerable to the smell of the paint. The paint is a waterproof coating for steel. At that time, I wondered if there could be an environmentally friendly coating instead that would not have such an intolerable smell. Later, when I saw this topic when choosing a topic, I chose it without hesitation. After contacting the instructor, Knowing that this topic is not very simple requires good professional knowledge and research spirit. But I can say that I know nothing about this topic, even the simplest components. After studying the chemical retrieval course, I have a good understanding of various aspects of the topic. Through mutual retrieval of large databases, I learned about the relevant knowledge of building waterproof coatings, preparation methods and formulas, and the production locations of some related coatings. I also learned about some relevant research in this area at home and abroad, which aroused my interest in this topic.
, although I am still an outsider, but I believe that interest is the first step to success. In the future, I will make better use of information retrieval as a tool to successfully complete this topic.
But I still feel inadequate in some places. Like many students, it is foreign language retrieval. I am unfamiliar with some English words in this major. This is also an area where I need to improve. I need to be more familiar with related English words and make Chinese and English interoperable.
7. Suggestions< /p>
I have benefited greatly from studying the literature retrieval course. I no longer let the school’s data resource library be wasted. I know how to find some professional documents I need, which will be helpful for my graduation thesis and beyond. The research on the topic has a very big effect. And Teacher Yang’s courseware is even more impressive, making it much easier to learn.
But in teaching, it may vary from person to person, and there are still some Things need to be improved. Sometimes the classroom atmosphere is still dull. We should create a relaxed and pleasant atmosphere that is conducive to all students participating in teaching, especially senior students. The teacher should properly complete the literature with the students while giving lectures. For retrieval, use more examples and less theoretical knowledge. Literature retrieval is a very practical course, allowing students to do more hands-on work and less theoretical knowledge.
However, in this course I learned a lot, which is inseparable from Teacher Yang’s hard work.
