preparation example Construction

[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, and disperse at a medium speed for 10-15 minutes until fully uniform, with a viscosity of 5000±500CPS / 25°C;

[0024] Step 2: Add silicon dioxide and pigments to the mixed solution obtained in step 1 and disperse them evenly;

[0025] Step 3: Add leveling agent and 0.8 to 1 part by weight of defoamer to the mixed liquid obtained in Step 2 and disperse evenly;

[0026] Step 4: Add the remaining defoamer to the mixture obtained in Step 3 and disperse evenly until the fineness is ≤20um, and the viscosity is controlled at 5000±500CPS / 25°C.

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.

Description

technical field [0001] The invention relates to a white finish paint, in particular to a bright white finish paint with black edges. Background technique [0002] As a traditional material in China, wood is deeply loved by Chinese people. With the improvement of people's living standards, the wooden furniture market has been widely developed. Before leaving the factory, wooden furniture needs to be painted multiple times to extend the service life of the wood. The wood paint can choose glossy white topcoat with black edges, etc., but the existing glossy white topcoat with black edges has the disadvantage that it is not easy to cover the edges and corners, especially it cannot effectively cover the boards whose edges and corners are pierced by sand. Easy to prickly heat, poor adhesion, low fullness, fast drying, and poor sagging resistance. Contents of the invention [0003] The invention provides a glossy white paint with black edges to improve the hiding performance and...
