Description

Technical Field

[0001] The utility model relates to the technical field of sheet material processing, in particular to a sheet material surface hard coating spray baking forming equipment. Background Art

[0002] PETG resin is an amorphous copolyester. The commonly used comonomer of PETG is 1,4-cyclohexanedimethanol (CHDM), the full name of which is polyethylene terephthalate-1,4-cyclohexanedimethanol ester. It is a product of terephthalic acid (TPA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM) by ester exchange polycondensation. PETG sheet has outstanding toughness and high impact strength. Its impact strength is 3 to 10 times that of modified polyacrylates. It also has a wide processing range, high mechanical strength and excellent flexibility. Compared with PVC, it has higher transparency, better gloss, is easy to print and has environmental advantages.

[0003] In the traditional sheet hard coating spraying process, the nano coating is often more fluid, and the coating is prone to accumulation in the baking stage after wet spraying. In addition, a scraper is added to the equipment. After the scraper coating accumulates, the subsequent sheets entering the equipment will be contaminated by the excess coating, increasing the defective rate of the sheet. At the same time, a utility model is proposed to solve the above problems. Utility Model Content
