Abstract

The invention relates to a polyolefin material with a spray-free metal effect and a preparation method and an application thereof. The polyolefin material with the spray-free metal effect comprises the following components in part by weight: 5-30 parts of modified spherical micro-particles, 50-80 parts of polyolefin polymer, 0.5-10 parts of sheet metal-effect pigment and 0.1-10 parts of auxiliaryagent; the modified spherical micro-particles are spherical micro-particles modified with a surfactant. According to the polyolefin material with the spray-free metal effect and the preparation methodand the application thereof, the spherical micro-particles are modified by using the surfactant to greatly improve the dispersibility of the spherical micro-particles; the modified spherical micro-particles are good in dispersibility; the sheet metal-effect pigment at the melt junction can be inhibited to deflect with the melt flow direction through the steric hindrance effect to achieve the purpose of eliminating the welding mark of the polyolefin material with the spray-free metal effect; the existing process and equipment do not need to be improved, thus the cost is low.

Description

technical field [0001] The invention belongs to the field of plastic coloring, and in particular relates to a polyolefin material without spraying metal effect and its preparation method and application. Background technique [0002] At present, as all walks of life pay more and more attention to environmental protection issues, plastic products without spraying metal effects are gradually gaining people's favor. Spray-free plastics can reduce painting or electroplating production processes and avoid environmental pollution, and spray-free plastics can also achieve diversified metal effects to meet the diverse needs of consumers and have huge market potential. However, there are still deficiencies in the realization of the current spray-free metal effect. Due to the use of flake pigments such as metal flakes or pearl powder, during injection molding production, when the melt flows in the mold, the pigments are oriented in the flow direction. When the melt flow is deflected,...
