Abstract

The invention discloses a PVC environment-friendly color master batch which is prepared from the following raw materials in parts by weight: 40-60 parts of a pigment, 30-40 parts of a resin matrix, 15-20 parts of a dispersing agent, 8-10 parts of poly(1, 6-hexanediol succinate), 6-9 parts of flame-retardant micro-nano spheres, 5-7 parts of wet ultrafine calcium carbonate and 0.5-1 part of a processing agent. The PVC environment-friendly color master batch is prepared by the following steps: S1, drying raw materials; S2, premixing; S3, obtaining a premix; and S4, carrying out extrusion granulation and water-cooling grain-sized dicing. A resin matrix adopted in the color master batch disclosed by the invention is used as a carrier of pigment, and the resin matrix comprises PVC resin, polylactic acid and polycarbonate resin. Under the modification effect of poly(1, 6-hexanediol succinate), the PVC resin has good biodegradability. The raw materials are all green and environment-friendly. Because of the addition of the flame-retardant nano microspheres, the color master batch is endowed with good flame retardance, and the obtained PVC color master batch has the advantages of being environment-friendly, flame-retardant, high in toughness and the like and can be widely used.

Description

technical field [0001] The invention belongs to the technical field of color masterbatches, and in particular relates to a PVC environment-friendly color masterbatch. Background technique [0002] Polyvinyl chloride (PolyvinylChloride, hereinafter referred to as PVC) is a non-toxic, odorless white powder. In China, the production and consumption of PVC rank first among the five general-purpose resins. According to statistics, the total output value of PVC in China in 2008 was close to 67 billion yuan. The market for PVC downstream products is even wider. In 2008, the output value of downstream products using PVC as raw material exceeded 100 billion yuan. In the field of rigid PVC, profiles and profiled materials are the largest consumption areas of PVC in my country, accounting for about 25% of the total consumption of PVC. They are mainly used to make doors and windows and energy-saving materials, and PVC pipes are the second largest consumption area. , accounting for abo...
