Embodiment 1
[0025] The matrix resin adopted in the present invention is saturated polyester resin, and saturated polyester resin is a kind of polyester resin with higher reactivity, and the prepared coating can also realize curing under high temperature conditions, and the full armor that curing agent adopts A mixture of etherified amino resins and partially methylated amino resins. Partially methylated amino resins can effectively increase the ratio of imine groups to methoxy groups in paints, thereby increasing the hardness of the paint layer without using partial methyl ethers. Amino resins are all used to replace full methyl etherified amino resins, because the ratio of imine groups to methoxy groups is too high, which will cause the paint layer to become brittle and lack toughness. Polytetrafluoroethylene wax powder can improve wear resistance and prevent material Surface scratches, improve sliding properties, reduce friction, noise and adhesion between materials, and prepare material...
