Abstract

The invention provides a special color master batch for a non-woven fabric, wherein the special color master batch comprises the following raw materials in parts by weight: 50-60 parts of a polypropylene resin, 20-30 parts of an organic pigment, 3-8 parts of a dispersing agent, 4-6 parts of a coupling agent, 2-6 parts of a flame retardant, and 2-5 parts of a lubricant. The invention further discloses a preparation method of the special color master batch for the non-woven fabric. According to the invention, the polypropylene resin adopted by the invention is a hydrocarbon polymer, the molecular chain contain tertiary carbon atoms, cracking easily occurs at the tertiary carbon atoms after being heated and illuminated, the prepared non-woven fabric fiber product is easy to diffuse at high temperature by adding the dispersing agent, the coupler and the lubricating agent, the quality of the non-woven fabric fiber product is not damaged, the non-woven fabric fiber product is not faded, andgood light resistance and abrasion resistance are achieved.

Description

technical field [0001] The invention mainly relates to the technical field of color masterbatches, in particular to a special color masterbatch for non-woven fabrics and a preparation method thereof. Background technique [0002] Color masterbatch is a mixture of resin and a large number of pigments or dyes to make a high concentration of color. Color masterbatch, also known as color species, is an aggregate made by uniformly loading super-normal pigments or dyes in resin. When processing, a small amount of color masterbatch and uncolored resin is mixed to achieve the colored resin or product with the designed pigment concentration. [0003] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics are moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, a...
