Problems solved by technology

These methods have high processing costs and strict construction requirements. The key is that the material that is electroplated or coated is not flexible enough and has insufficient adhesion. When the plastic titanium is bent at 90 degrees, the paint film on the frame is easy to burst, which affects the appearance and use of the frame.

Abstract

The invention discloses a special paint for plastic cement materials, which is characterized by comprising a component A and a component B, and is matched with a thinner, wherein the component A comprises the following ingredients in percentage by weight: 48-52% of acrylic acid resin, 23-27% of polyester resin, 14-16% of epoxy modified resin, 0.5-1% of accessory ingredient and 6-10% of butyl acetate; the component B is a curing agent; the thinner comprises the following ingredients in percentage by weight: 90% of methyl isopropyl ketone (MIBK) and 10% of butyl acetate; the ratio of the component A to the component B to the thinner is 4:1:2; and the component A and the component B are mixed and evenly stirred in ratio. The special paint disclosed by the invention has excellent adhesive force and good flexibility and glossiness and is convenient to construct.

Description

technical field [0001] The invention relates to a special paint for special materials, in particular to a special paint for plastic titanium materials. Background technique [0002] Plastic titanium (TR-90) is a polymer material with super toughness and special memory function. The material can still return to its original shape after being bent at 90 degrees. The material is light, 30% lighter than acetate plastic (CA). The impact resistance of the material is more than 2 times that of acetate plastic (CA). The material is resistant to high temperatures, can withstand high temperatures of 350 degrees for a short time, and is not easy to melt and burn. It is currently widely used in eyeglass frames. At present, for the treatment of the surface of the eye frame, the commonly used methods generally include electroplating precious metals, using ionized titanium compounds for sputtering ion coating method, electroplating on the substrate in advance and color plating of electrod...
