Multi-color-selection and multi-base-material laser welding light-transmitting color master batch and preparation method thereof

Abstract

The invention discloses a multi-color-selection and multi-base-material laser welding light-transmitting color master batch and a preparation method thereof. The multi-color-selection and multi-base-material laser welding light-transmitting color master batch is prepared from the following raw materials in parts by weight: 78-99.4% of carrier resin, 0.01-5% of solvent blue, 0.01-5% of solvent yellow, 0.01-5% of solvent red, 0.01-5% of solvent violet, 0.01-1% of a dispersant, and 0.01-1% of a processing stabilizer. According to the invention, various colors including black are adjusted on the premise that the laser transmittance is guaranteed through combination of the toner, the defect that a conventional laser welding light-transmitting master batch is limited to be black is overcome, the compatibility of a carrier and a dispersing agent of the color master batch with various base materials such as PC, ABS, PA and PBT is improved through a pretreatment process, the application range of the laser welding light-transmitting color master batch is widened, when a resin base material changes, the component proportion can be adjusted to eliminate the influence caused by the change of the base material, and the color stability is improved, which cannot be achieved by conventional single dye black, and the processing stabilizer improves the color stability of the laser welding light-transmitting color master batch under a high-temperature condition in the processing process.

Description

technical field [0001] The invention relates to the field of polymer material coloring, in particular to a multi-color selection, multi-substrate application laser welding light-transmitting color masterbatch and a preparation method thereof. Background technique [0002] The welding process of laser welding is a heat conduction type. Laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Compared with other welding techniques, laser welding mainly has the following advantages: 1. Fast speed, large depth, and small deformation; 2. Can weld refractory materials such as titanium, quartz, etc.; 3. Can perform micro-welding and can be applied It is used in the assembly welding of micro and small workpieces produced in large quantities and automatic...

Problems solved by technology

The currently published technologies are all aimed at laser welding compositions of a single material or a single color. There are relatively few studies on color masterbatches for laser welding, especially the lack of in-depth research on color masterbatches suitable for multi-substrate and multi-color selection. , multi-color selection, research on laser welding light-transmitting masterbatches applied to substrates is of great significance for increasing the application of laser welding forming technology
