Problems solved by technology

At present, domestic ballast manufacturers generally adopt the production process of double immersion and double drying or double immersion and one drying. The production efficiency is low, and the uniformity of the ballast surface after dipping is poor.
At the same time, due to the defects of insulating paint materials, it is difficult to meet the requirements of uniform paint film coverage, strong adhesion, no yellowing, and smooth appearance after one baking at the same time.

Embodiment 1

[0018] The specific preparation method is as follows:

[0019] a) Paint grinding treatment, the specific preparation process is: first add 60% heat-resistant unsaturated polyester resin, 7% xylene and 10% mixed dibasic ester solvent into the paint grinding tank, and disperse at a high speed of 2500r / min 15min; then add 20% new titanium dioxide to the above mixed raw materials, and disperse at a high speed of 2500r / min for 30min; finally add glass beads accounting for 30% of the total amount of the above mixture, turn on the cooling water, and disperse at a high speed of 3800r / min for 5h .

[0020] b) Paint letdown treatment, the specific preparation process is: first pour the mixed raw materials prepared in step a) into the paint letdown tank; then add 1.9% curing agent, 0.1% polymerization inhibitor and 0.5% catalyst to the paint letdown tank at one time , 0.2% leveling agent and 0.3% defoamer, and fully stirred, the stirring speed is 2800r / min, and the stirring time is 0.5h...

Embodiment 2

[0022] The specific preparation method is as follows:

[0023] a) Polishing treatment, the specific preparation process is: first add 40% polyimide and polyamideimide mixed resin, 11% xylene and 15% mixed dibasic ester solvent into the grinding paint tank, and use 2500r / min speed of high-speed dispersion for 15 minutes; then add 30% new titanium dioxide to the above mixed raw materials, and disperse at a high speed of 2500r / min for 30min; finally add glass beads accounting for 40% of the total amount of the above mixture, turn on the cooling water, and use 3800r / min Disperse at high speed for 5 hours at min speed.

[0024] b) Paint letdown treatment, the specific preparation process is: first pour the mixed raw materials prepared in step a) into the paint letdown tank; then add 2.2% curing agent, 0.2% polymerization inhibitor and 0.7% catalyst to the paint letdown tank at one time , 0.4% leveling agent and 0.5% defoamer, and fully stirred, the stirring speed is 2800r / min, an...

Abstract

The invention discloses novel insulating paint for ballast and a preparation method of the insulating paint. The insulating paint contains the components in percentage by weight: 40-60% of resin, 7-11% of xylene, 10-15% of mixed dibasic ester solvent, 20-30% of novel titanium white, 1.9-2.2% of curing agent and 1.1-1.8% of adjuvants. The preparation method comprises the following steps: (a) grinding paint; and (b) preparing paint. According to the novel insulating paint for the ballast and the preparation method of the insulating paint, disclosed by the invention, the insulating paint is excellent in performance, has strong adhesive power and good rust resistance and can enable the ballast to have a flat, smooth and non-yellowing appearance after paint dipping; the preparation method is simple and convenient and meets the process requirements on one-dipping and one-baking, and thus, the production efficiency can be doubled.

Description

technical field [0001] The invention relates to an insulating varnish, in particular to a novel insulating varnish for a ballast and a preparation method thereof, belonging to the technical field of insulating materials. Background technique [0002] Insulating varnish is an important insulating material based on high molecular polymer, which can be cured into an insulating film or an insulating whole under certain conditions. Insulating varnish has a wide range of uses, and its types mainly include: enameled wire insulating varnish, impregnated insulating varnish, covering insulating varnish, silicon steel sheet insulating varnish, bonding insulating varnish, electronic component insulating varnish, etc. An insulating varnish with excellent performance should have excellent insulation performance, good adhesion, small shrinkage stress, high heat resistance, low toxicity and non-toxicity, and be able to meet special requirements such as radiation protection, corrosion resist...
