  • Publication number: 20240239059
    Abstract: A molding method of a support rod that first passing a plurality of long fibers through a resin bath for impregnating with resin, then passing the plurality of long fibers impregnated with resin through a bundling hole of a position-constrained vertical plate on a machine to preliminarily form a bundle end; providing a coating layer on the machine, one end of the coating layer obliquely passes through a guiding portion on the position-constrained vertical plate to downwardly contact the bundle end; then placing the one end of the coating layer and the bundle end into a mold cavity of a mold at the same time to form a long rod body; and then cutting the long rod body into multi-segment support rods through a cutting process.

  • Patent number: 10745556
    Abstract: Provided are an amino resin composition, a varnish, a coating layer, and a product. The amino resin composition comprises a repeating unit represented by the following Formula (I): A 13C-NMR spectrum of the amino resin composition has a first characteristic peak at 159 ppm to 161 ppm and a second characteristic peak at 70 ppm to 80 ppm. Based on the integral value of the first characteristic peak as 1, the integral value of the second characteristic peak is in the range from 0.01 to 0.25. Adopting the amino resin composition can accelerate the drying of the varnish and ensure the coating layer and the product have high hardness, high gloss and excellent color stability.
