Preparation and Properties of Water Soluble Copolyester for Coating Solution
In this experiment, water soluble polyester (WSPET) was synthesized by two-step esterification with terephthalic acid (PTA), isophthalic acid (IPA), sodium phthalic acid-5-sulfonate (5-SSIPA), ethylene glycol (EG) and dihydroxymethyl propionic acid (DMPA) as raw materials, tetrabutyl titanate as catalyst. BOPET/WSPET composite membrane was prepared by emulsion crosslinking with hexa(methoxymethyl) melamine (HMMM) as crosslinking agent by the coating method. The effects of different amounts of 5-SSIPA and DMPA on the contact angle, thermal properties, boiling resistance, optical properties and physical properties of the samples were investigated. The result shows that with the increase of the amount of 5-SSIPA, the hydrophilicity of the water-soluble polyester increases, the glass transition temperature increases, and the boiling resistance decreases. With the increase of the amount of DMPA, the hydrophilicity of the water-soluble polyester is enhanced, the boiling resistance is enhanced, and the pencil hardness and adhesion of the composite membrane are significantly improved, but the flexibility is reduced. When the addition amount of 5-SSIPA is 50% (relative to IPA mole ratio) and the addition amount of DMPA is 250% (relative to IPA mole ratio), the comprehensive performance of the sample is the best.
