In view of the current situation and existing problems of traditional nitrocellulose coatings,the key technology and application research products of new nitrocellulose coatings were developed with low cost and easy to obtain raw materials such as fatty acid,glycerol,phthalic anhydride,etc.At the same time,the new nitrocellulose coatings were developed with thermoplastic acrylic resin instead of nitrocellulose various factors affecting the preparation of nitro coatings were discussed emphatically.The developed products have excellent properties and improve the safety of the coatings during production and transportation.
