Document Type and Number:
WIPO Patent Application WO/2023/174010
Kind Code:
A1
Abstract:
Disclosed in the present invention are a spraying-free effect pigment, a preparation method therefor and an application thereof. The spraying-free effect pigment comprises the following components in parts by weight: 100 parts of effect pigment, 10-200 parts of coupling agent, and 10-200 parts of thermosetting resin microspheres, wherein the effect pigment is in a sheet shape, and the average particle size is 6-350 μm; and the ratio of the average particle size of the thermosetting resin microsphere to the average particle size of the effect pigment is 1:(3-100). According to the present invention, the steric hindrance effect of the small-particle thermosetting resin is synergistically improved, such that the spraying-free effect pigment is added into a plastic matrix, a good spraying-free metal effect can be brought, and the phenomena of weld marks and flow marks are avoided.
