Regarding the biological buffer TRIS, I believe that many people have seen its magical powers. It can be seen everywhere in skin care products, pharmaceutical intermediates, pharmaceutical excipients, and buffers, but it has another application that many people do not understand. Yes, today we will find out what role TRIS plays in coatings.
TRIS mainly plays the following four functions in the coating preparation process: pH adjuster, crosslinking accelerator, polyester coating raw material and phase change core material. The following is a detailed introduction to how TRIS plays these roles.
1. pH adjuster
TRIS is a weak base with a pKa of 8.1 at 25°C; according to buffer theory, the effective buffering range of Tris buffer is between pH 7.0 and 9.2. The pH of the aqueous solution of Tris base is about 10.5, and hydrochloric acid is generally added to adjust the pH to the desired value.
The pH value of the buffer can be obtained.
2. Cross-linking accelerator
TRIS is used as a cross-linking accelerator, which can act as a bridge between linear molecules, so that multiple linear molecules are bonded and cross-linked to form a network structure. It is a substance that promotes or regulates the formation of covalent bonds or ionic bonds between polymer molecular chains. Polyols are often used as crosslinking agents in the preparation of coatings.
3. Polyester coating raw materials
Polyester oligomers can be prepared by reacting polyols, polyacids, catalysts and antioxidants, which can be used as coating compositions.
4. Phase change core material
When the temperature reaches the phase transition temperature, the structure of the polyol phase change material will change from a layered body-centered structure to an isotropic face-centered structure. At the same time, the hydrogen bonds between the layers are broken, and the molecules will change from a crystalline state. For the amorphous phase transition, the bond energy is released.
The solid-solid phase transition enthalpy of polyol is relatively large, and its size is related to the number of hydroxyl groups contained in each molecule of the polyol. The advantages of TRIS are large phase transition enthalpy, stable performance and long service life.
