Spraying-free aesthetic resin composition with magnetism and preparation method thereof

The invention relates to a spraying-free aesthetic resin composition with magnetism. The resin comprises the following components in parts by weight: 70-90 parts of matrix resin, 0.1-2.0 parts of lubricant, 0.1-1.0 part of antioxidant and 10-30 parts of magnetic metallic pigment master batch. The magnetic metallic pigment master batch comprises the following components in parts by weight: 100 parts of matrix resin, 1.0-20 parts of magnetic metallic pigment, 1.0-30 parts of pearlescent pigment, 1.0-2.0 parts of lubricant and 0.1-0.3 parts of antioxidant. The preparation method comprises the steps of preparing the magnetic metallic pigment master batch; agitating and mixing the raw materials, extruding, drawing into bars, cooling and cutting into grains to obtain the spraying-free aesthetic resin composition. The spraying-free aesthetic resin composition with magnetism has the advantages that the flow marks and the weld lines occurring in the injection molding or extrusion process of the aesthetic resin containing aluminum powder pigment are effectively reduced, the metal effect of produced parts is enhanced at the same time, the amount of the used aluminum powder pigment is reduced and the cost is saved.
