Abstract

The invention discloses a delustering color master batch based on polytrimethylene terephthalate. The delustering color master batch comprises the following ingredients, by weight, 15%-40% of PTT, 20%-40% of titanium dioxide, 10%-30% of delustering agents, 5%-15% of light stabilizing agents, 5%-10% of fluorescent brighting agents, 8%-15% of 5-sulfoisophthalic acid monosodium salt, 3%-8% of compatilizer and 0.5%-3% of dispersants. The delustering agents are crosslinking butadiene-acrylonitrile polymers or crosslinking styrene-acrylonitrile polymers. The compatilizer is polymethyl methacrylate grafting maleic anhydride. The beneficial effects are that when the delustering color master batch is applied in PTT production, good low-gloss matte modification effects are achieved, the appearance is good, usage is convenient, the cost is low, the processability is good, the preparation technology is simple, and the delustering color master batch is helpful for cleaning production and raising the production efficiency.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a matting color masterbatch based on polypropylene terephthalate. Background technique [0002] Polytrimethylene terephthalate (PTT) is a new development after polyethylene terephthalate (PET) in the 1950s and polybutylene terephthalate (PBT) in the 1970s. Promising new polyester polymer material. Due to its excellent comprehensive performance, it has been widely used in the fields of fibers, monofilaments, films, engineering plastics, and non-woven fabrics. Especially in the field of engineering plastics, PTT has both the high performance of PET and the ease of processing of PBT, and its price is much lower than that of PBT. With the increasingly fierce market competition, various application fields have put forward higher requirements on the performance of PTT in all aspects. It is difficult for ordinary PTT to meet the needs of the industry. Usually, it can be modi...
