Figure 47 Effect of variables on fruit ester resins, polyresins with
Dimethyl. The glass transition diagrams of the polyester resins all changed when the new glycol was used to replace part of the glycol, x, and the chemical situation is shown in Figure 48. The data in the figure illustrate that for the dicarboxylic acid-ethylene glycol system, when substituting isophthalic acid for g 10 leaves Caking-resistant fraction of terephthalic acid, the glass transition temperature (T, stable region of polyester resin although there is a decline, but always not less than 50 ℃; however, when using diacid or sebacic acid to replace part of terephthalic acid, with the increase in the amount of 2 substitution, the glass transition temperature (T, of polyester resin quickly fell to below 50 ℃. Such resins with too low glass transition temperature (T) cannot be used to formulate powder coatings when this explains the difference in the effect of aromatic dicarboxylic acid and aliphatic dibasic cool copolymer composition (adipic acid, adipic acid, on the glass transition temperature (Tg) of polyester resins, car synthetic wax sebacic acid, neoteric diol) /(mol/10)

Figure 4-8 Effect of copolymer composition on polyester resin T, the aliphatic carboxylic acid makes the glass transition temperature (T) of polyester resin o terephthalic acid-isophthalic acid-ethylene glycol system: a significant decrease. In addition, the glass transition temperature (T,) o terephthalic acid-sebacic acid-ethylene glycol system of polyester resin when replacing e terephthalic acid-adipic acid-ethylene glycol system with branched neopentyl glycol: partial glycol.

A terephthalic acid-new tiger glycol glycol system is also always above 50°C, which is suitable for the basic requirements of powder coatings, indicating that the mutual substitution of branched and straight chain alcohols has that obvious effect on the poly temperature (T,) that The effect of the glass transition temperature (T,) of polyester resin is not like the effect of aromatic binary carboxylic acid on the glass transition temperature (T,) and brittleness of polyester resin after being replaced by aliphatic carboxylic acid in polyester resin synthesis formulation, terephthalic acid and isophthalic acid can improve the glass transition temperature (T,) and brittleness of polyester resin, which is good for the storage stability and weathering resistance of powder coatings, and can also improve the miscibility with epoxy resin and the wettability of color filler, trimellitic anhydride It can also improve the miscibility with epoxy resin and the wettability of color filler, trimellitic anhydride can improve the functionality of resin, improve the reactivity during cross-linking and curing, and also improve the cross-link density of coating film and improve the mechanical properties of coating film. The straight-chain diols can improve the molecular weight and flexibility of the resin, but have a bad effect on the glass transition temperature (T,) and water resistance of the coating film.
