Problems solved by technology

The color paste dyeing has the following problems: 1. The storage performance is poor, and the color paste will settle and delaminate if it is not used for a day; 2. The color paste has the defects of polluting the environment and processing equipment
Because the color paste is difficult to clean, workers need to spend a lot of time cleaning equipment, hoppers and the environment after each production. They can only wipe it with organic solvents. The volatiles are discharged into the atmosphere and cause exhaust gas pollution. There will be a certain amount of residue and waste every time; 3. The concentration of the color paste cannot be made higher (currently 5%)
Since the amount of color paste added in this industry is usually 3 to 8 / 10,000, if the concentration of color paste is increased, the amount of color paste added will be less. If the dispersion is not uniform enough, the problem of color inaccuracy will easily occur.

Abstract

The invention provides a dyeing composition, a preparation method and a dyeing technology. The dyeing composition is solid particles and is prepared from, by weight, 3%-75% of pigments, 1%-3% of a dispersing agent, 5%-10% of a high-molecular polymer and 12%-91% of a low-molecular polymer, wherein a resin polymer is adopted as the high-molecular polymer, and a wax substance is adopted as the low-molecular polymer. The pigment content of the dyeing composition can reach up to 75%, the dispersity is good, and equipment and an environment are easy to clean when the dyeing composition is used.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a dyeing composition, a preparation method and a dyeing process. Background technique [0002] In the current plastic dyeing market, there are three main types of dyeing materials, namely toner, masterbatch, and color paste, as follows: [0003] Regarding toner, in plastic products, most companies still use toner, such as carbon black. The advantage of toner is that the unit price is relatively low, which is more suitable for enterprises with stricter cost requirements. The disadvantages are also obvious: first, during the processing, the toner dust pollution is very large, and will cause secondary pollution of the product; second, since the toner is usually a chemical, the dust of the toner is very harmful to the health of the employees. And in the processing process, the reusability of resin added with toner is poor, especially some important colors. [0004] Masterbatches ar...
