Abstract

The invention discloses a nitrocellulose varnish and a preparation method thereof. The raw material formula of the nitrocellulose varnish contains two components, namely main agent and electrostatic thinner; by reasonably selecting materials and adjusting the proportions of the materials, the nitrocellulose varnish has the same performance requirement on hardness, luster, hand feeling, adhesive force and the like as the conventional product; and by adjusting the formulas of the main agent and the electrostatic thinner, the nitrocellulose varnish disclosed by the invention has good conductivity, volatile speed, anti-sagging property, elevation levelling property and other performances. The nitrocellulose varnish disclosed by the invention is suitable for the electrostatic spraying process;compared with the air spraying nitrocellulose varnish, the utilization rate of the paint can be greatly increased; the nitrocellulose varnish is suitable for special-shaped pieces such as guitars andornaments; and the cost of the paint is greatly reduced, the loss is reduced and the pollution to the environment is lowered.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to coating technology, in particular to a nitro varnish suitable for an electrostatic spraying process and a preparation method thereof. Background technique [0002] At present, the nitro varnish used in the production of wood products such as musical instruments, handicrafts, and decorations is generally applied by compressed air spraying and brushing. Using conventional compressed air spraying, brushing and other processes, there are problems such as low paint utilization rate, large loss, large environmental pollution, high labor cost, low work efficiency, and difficult control of coating film quality by manual operation. [0003] At present, the process of using electrostatic spraying in industrial manufacturing is very mature, but because electrostatic spraying needs to put forward special requirements on the electrical conductivity, anti-sagging energy, and facade leveling pe...
