Problems solved by technology

The invention does not contain small molecular substances, increases the oil resistance and flux resistance of the color masterbatch, improves the migration resistance of the color masterbatch, and cannot cause precipitation in plastic products, but the carrier used in the preparation method is polyethylene, which is non-degradable Materials, and the pigments and additives used, there are heavy metals exceeding the standard, resulting in serious pollution of the land and cannot be planted again
[0004] In addition, at present, after most of the masterbatches are made into heavy-duty plastic products, such as water pipes, gears, casings, etc., when the load reaches or exceeds the warning weight, there is no relevant intelligent monitoring system to monitor it in real time to display its load. The degree of damage under pressure will virtually increase the damage rate and use cost of plastic products

Abstract

A degradable compressive discoloring plastic color masterbatch consists of the following substances by the mass fraction: 10-30% of a pigment, 10-40% of a filler, 0.1-1% of a coupling agent, 0.5-5% ofa lubricant, 40-80% of a carrier and 4-10% of a pressure sensitive discoloring material. With polylactic acid or butylene terephthalate as a carrier, the proportion of the pigment and the additive isoptimized, the degradable compressive discoloring color masterbatch is obtained, has the advantages of uniform coloring, low cost, easy control of processing technology, excellent dispersibility andthe like, and has broad industrial application prospects.

Description

technical field [0001] The invention belongs to the field of plastic coloring, and in particular relates to a degradable pressure-changing plastic color masterbatch and a preparation method thereof. Background technique [0002] Color masterbatch is a plastic coloring product developed in the 1960s. It is a polymer compound prepared by uniformly loading pigments in resin. It has the advantages of convenient use and stable color; color masterbatch Granules have entered China for more than 40 years. The variety has grown from scratch, and the output and quality have been greatly improved compared with the beginning of development. It is also widely used in the fields of plastic products such as films, plastic products, chemical fibers, cables, and building materials. Colored with masterbatch. [0003] Patent 107973957A discloses a precipitation-preventing masterbatch, which consists of the following components in parts by weight: 15-50 parts of polyethylene, 5-50 parts of pig...
