What is the role of plasticizer and dibutyl in building waterproof coatings

The functions of plasticizer and dibutyl in building waterproof coating are as follows:
1. Plasticizer, also known as dioctyl ester, is used to plasticize, which can improve the flexibility and low-temperature performance of film-forming, and improve the compactness of waterproof coating.
2. Dibutyl ester is mainly used as auxiliary plasticizer of polyvinyl chloride. Compared with dioctyl ester, dibutyl ester is easy to migrate and is often used in combination with dioctyl ester to reduce the addition cost of plasticizer.
plasticizer (Plasticizer) is a kind of polymer material additive, and it is also a phthalate ester in environmental estrogen. It has a wide variety, and the common variety is DEHP. DEHP chemical name di (2-ethylhexyl) phthalate, is a colorless, odorless liquid, widely used in industry. Plasticizer is a polymer material additive widely used in industry. Adding this substance in plastic processing can enhance its flexibility and easy processing.
 

The significance and function of rubber blending are briefly described

The significance of rubber blending is to improve the process performance, service performance and technical and economic performance. More than 70% of rubber is processed and used in the form of rubber or rubber and plastic.
The process compatibility of rubber, through mechanical methods or other conditions, the thermodynamic incompatible system can be mixed to obtain a sufficiently stable blend, which forms a multiphase morphology in the micro region, but still maintains its uniformity in the macro.
Factors affecting polymer blending:
Mixing process conditions: time, strength, roll temperature, processing method
Formula composition: raw rubber, blending ratio, compatibilizer, processing aids
