Abstract
A fast -drying bottom coating, specifically a self -dry polyurethane anti -static paint.Involved in the field of chemical coatings preparation technology, the following raw materials are made of: 60‑80 copies, 50‑70 copies of polyurethane of glycopic acid, 3‑5 cobalt -cobaltate, 4 to 6 copies of solid fatty acid zinc, 6‑8 nylon 6‑8Severe, 3 to 5 copies of acrylate, 5‑7 parts of nano -zinc oxide, 80 to 90 parts of tailphenols, 1 to 3 parts of organic silicon, 6 ‑, 3 to 5 parts of silicon dioxide, and 3 to 5 parts of stems.Titanium dioxide 5‑7 parts, asphalt 3‑5 parts, nano -oxide dioxide 5‑7 parts, 6‑8 part of sulfuric acid, 35‑45 aluminum emulsion, and 220‑230kg of removal water.The beneficial effect of the present invention is: the process of the present invention is simple and the raw material ratio is reasonable. It uses acrylic polyurethane and alcohol -polyurethane as the main material, with the use of paraffin emulsion and the remaining aids, to obtain self -dry coatings, faster solidification, faster, and faster.After spraying, it can be completely solidified by 5 ,7 hours at normal temperature, fast and efficient, and easy to promote and use.
Description
technical field [0001] The invention relates to the technical field of chemical paint preparation, in particular to a self-drying polyurethane antistatic paint. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film.The film formed in this way is commonly called coating film, also known as paint film or coating. [0003] Polyurethane paint is polyurethane paint. It has strong paint film, full luster, strong adhesion, water resistance, wear resistance and corrosion resistance. It is widely used in high-grade wooden furniture, and can also be used on metal sur...
