Antistatic color gel coat and preparation method thereof

Abstract

The invention discloses an antistatic color gel coat and a preparation method thereof. The antistatic color gel coat is prepared from the following components in parts by weight: 100 parts of matrix resin, 8 to 20 parts of styrene, 10 to 30 parts of functional filler, 2 to 3 parts of a thixotropic agent, 0.12 to 0.2 part of a thixotropic stabilizer, 1 to 10 parts of an antistatic agent, 0.4 to 1 part of a surface auxiliary agent, 10 to 20 parts of color paste, and 0.1 to 0.4 part of an accelerant. The preparation method comprises the following steps of: putting the matrix resin into a dispersing kettle at first, adding the functional filler under stirring, then dispersing, adding the thixotropic stabilizer, adding the thixotropic agent under stirring, and dispersing again to obtain a matrix gel coat; and adding the color paste, the styrene, the antistatic agent, the surface auxiliary agent and the accelerant into the matrix gel coat, and uniformly stirring to obtain a finished product of the antistatic color gel coat. The antistatic color gel coat is controllable in gelatination and curing time, stable in surface resistance and rich in color.

Description

technical field [0001] The invention relates to a gel coat and a preparation method thereof, in particular to an antistatic colored gel coat and a preparation method thereof. Background technique [0002] Gel coat is a surface material with certain thixotropy, good rheology and excellent mechanical properties obtained by adding thixotropic agent and rheological additive to a suitable matrix resin through high-speed dispersion or grinding. Due to its good comprehensive performance, it is widely used in the fields of ships, vehicles, kitchen and bathroom, construction, anti-corrosion, flame retardant and so on. [0003] The colors of existing gel coats are mainly concentrated on darker colors such as black, dark green, and dark army green. The gel coats of these darker colors are unstable in gelation and curing, so they are easy to solidify during storage. [0004] The gel coats with lighter colors (such as light yellow, sky blue, white and other colors) have been difficult t...

Problems solved by technology

[0003] The colors of existing gel coats are mainly concentrated in darker colors such as black, dark green, and dark army green. The gel coats of these darker colors are unstable in gelation and curing, so they are easy to cure during storage.

[0004] However, gel coats with lighter colors (such as light yellow, sky blue, white and other colors) are difficult to control the gelation and curing time in the production process, making it difficult to be practically used in production for a long time.
