Abstract

The invention provides a black-edge-covering bright white paint that is prepared from a component A, a component B and a component C, wherein the component A is prepared from the following raw materials in parts by weight: 34-48 parts by weight of synthetic fatty acid resin, 10-20 parts by weight of vegetable oil acid resin, 5-8 parts by weight of acrylic resin, 0.5-0.8 part by weight of silicon dioxide, 37-40 parts by weight of pigment, 0.2-0.3 part by weight of dispersing agent, 0.5-0.9 part by weight of leveling agent and 1.8-3 parts by weight of defoamer. The component B is a light curingagent, and the component C is a light diluent. Detection and use prove that the black-edge-covering bright white paint has excellent covering power for a plate of which corners are not easy to cover or corners of a substrate are sanded; the paint is not easy to miliaria, and has excellent adhesive force, high fullness, high dryness and strong sinking resistance.

Example Embodiment

[0022] The preparation method of the first component of the embodiment of the present invention is as follows:
[0023] Step 1: Mix synthetic fatty acid resin, vegetable oleic acid resin, acrylic resin and dispersant, disperse at medium speed for 10-15 minutes until fully uniform, and the viscosity is 5000±500CPS/25℃;
[0024] Step 2: add silica and pigment to the mixed solution obtained in step 1 and disperse uniformly;
[0025] Step 3: add a leveling agent and 0.8 to 1 part by weight of a defoaming agent to the mixed solution obtained in step 2 and disperse evenly;
[0026] Step 4: Add the remaining defoamer to the mixed solution obtained in Step 3 and disperse it evenly until the fineness is ≤20um, and the viscosity is controlled at 5000±500CPS/25℃.
