Abstract

The invention discloses a preparation method of PE (Polyethylene) black backing varnish. The PE black backing varnish comprises a first component and a second component; various ingredients of the first component are mixed at the ratio and then are scattered at a speed of 1200-1400 revolutions per minute for more than 20 minutes, and then the temperature is reduced to less than 40 DEG C; various ingredients of the second component are mixed at the ratio, then are scattered at a speed of 1200-1400 revolutions per minute for more than 20 minutes, and then are grinded to particles with a fineness being less than 50 microns; the treated first component and the treated second component are mixed with 3-7 parts of a solvent, and then the mixture is scattered at a speed of 800-1000 revolutions per minute for more than 10 minutes to acquire a finished product. The PE black backing varnish prepared through the method has the advantages of long storage time, difficulty in flocculation and capability of being applied to industrial production instead of black backing varnish in the prior art.

Description

technical field [0001] The invention relates to the field of PE paint, in particular to a preparation method of PE black primer. Background technique [0002] Polyurethane paint, also known as PU paint, is generally composed of isocyanate prepolymers (also known as low molecular carbamate ester polymers) and hydroxyl-containing resins, commonly known as curing agent components and main agent components. Polyurethane paint film is tough, full of luster, strong adhesion, water-resistant, wear-resistant, and corrosion-resistant, but it has problems such as blistering when it is wet, powdering of the paint film, and TDI content. [0003] Unsaturated polyester paint, also known as PE paint, is cured by blending the main agent, accelerator and initiator for polymerization and bridging reaction. The solvent can be styrene, which participates in the reaction when forming a film, and has a full Good temperature, fast drying speed, suitable for industrial assembly line production and...
