Abstract

The invention discloses a neopentyl glycol resin. The neopentyl glycol resin mainly comprises the following raw materials by mass percentage: 30 percent of neopentyl glycol, 6 to 8 percent of adipic acid, 20 to 25 percent of isophthalic acid, 6 to 8 percent of trimellitic anhydride, 2 to 4 percent of terephthalic acid, 0.1 percent of catalyst, 15 to 20 percent of S-150, 10 to 15 percent of DBE (dibasic ester) and 3 to 5 percent of dimethyl benzene, wherein all the raw materials are physically mixed to obtain the neopentyl glycol resin. The neopentyl glycol resin is an environment-friendly composite coating, has good antiseptic and anti-rust effects and good medium resistance and is environment-friendly.

Description

Technical field [0001] The invention relates to a material resin, especially a neopentyl glycol resin, which is suitable for various coiled steel plates. Background technique [0002] At present, the main anti-rust raw materials for coatings for pre-coated coiled steel sheets are strontium chromate and zinc chromate, which have strong anti-rust ability, good water solubility, and high temperature baking resistance, but are highly toxic and harmful to humans. , is not conducive to environmental protection. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a neopentyl glycol resin. The resin not only has a novel formula, is easy to operate, is safe and non-toxic to use, does not contain heavy metal materials harmful to the human body, but also has a more environmentally friendly coating film, strong anti-corrosion and anti-rust capabilities, meets the physical properties of color...
