Embodiment Construction

[0008] 1. The speed of ball milling is 45-60 rpm, and when the fineness reaches 5 microns, add matting agent and leveling and smoothing agent to disperse and make the main agent.

[0009] 2. The solvent is prepared from propylene glycol, butyl acetate and heavy aromatic hydrocarbon S-100B.

[0010] 3. When adding matting agent and leveling and smoothing agent, the dispersion speed is 1800-3500 rpm, and the time is 8-28 minutes.

[0011] 4. The surface additive is made of aromatic polyisocyanate resin, butyl acetate and silicone. Matching ratio 1.8-2.1: 1.2-0.9: 0.006-0.01.

[0012] 5. Implementation example:

[0013] The main ingredient is formulated (weight KG) Degussa acrylic resin 60, solvent 24 (propylene glycol, butyl acetate, heavy aromatic hydrocarbon S-100B prepared in a ratio of 1:3:4), pigment 8. After pre-mixing each material, add and carry out ball milling, the rotating speed is 45] rpm, when the fineness of the slurry reaches 5 microns, it will be discharged, t...

Abstract

A preparation method of an environmentally-friendly blackboard paint comprises the following steps: pre-mixing Degussa resin, a solvent, a pigment, a wetting dispersant, an antifoaming agent and a surfactant, carrying out ball milling, adding a flatting agentand a leveling smoothing agent when the fineness reaches 5-8 [mu]m to carry out dispersion in order to prepare a main agent, uniformly mixing the main agent with a special curing agent and a diluent during construction in proportion for coating. The paint prepared in the invention has the advantages of no light reflection, dustiness resistance, good adhesion, scrubbing resistance, anticorrosion, high ageing resistance and no cracking, and is suitable for coating blackboards with the substrates being cement plates, iron plates and glass plates.

Description

technical field [0001] The invention relates to a preparation method of blackboard paint. Background technique [0002] The blackboards used for teaching in many schools are permanent. Under the strong outdoor light, local reflections will occur, which not only affects the students to see the teacher's writing on the blackboard clearly, but also damages the health of teachers and students' eyes. Therefore prepare environment-friendly blackboard paint, solve the above problems, become the demand of market. Contents of the invention [0003] The purpose of the present invention is to provide an environmentally friendly blackboard paint that is non-reflective, dust-resistant, plump, smooth, bright in color, good in flexibility, strong in adhesion, scrubbing resistant, anti-corrosion, anti-aging, and non-cracking. . [0004] The object of the present invention is to adopt the following method to realize: [0005] Premix Degussa PQ611 acrylic resin, solvent, pigment, wetting...
