Abstract:

In order to prepare UV curable melamine resin,hydroxyethyl acrylate (HEA) was used to modify methyl etherified melamine resin (HMMM). The unsaturated C=C double bond was introduced to increase the photocurability of melamine resin.The structure of the product was characterized by infrared spectroscopy.As a result,amino acrylate (HEA-MF) is successfully synthesized.Then,the photocurable melamine resin film and coated fabric were prepared,and the thermal property of the film was characterized by Thermal Gravity Analysis(TGA).The mechanical properties,stiffness,wear resistance,waterproof,moisture permeability and air permeability of coated samples were analyzed.The results show that under 300 ℃,the UV-cured film has stable structure and good thermal stability,it begins to lose weight quickly at 350 ℃.After coating,the breaking strength,stiffness and abrasion resistance of the fabric are improved.The fabric elongation at break,moisture permeability and air permeability are adversely affected,but the waterproof properties of the coated fabric are outstanding.

Key words: melamine resin, UV curing, amino acrylate, coating fabric, waterproof
