Abstract

The invention belongs to the technical field of high-molecular materials, and relates to a universal fully-biodegradable color masterbatch and a preparation method thereof. The universal fully-biodegradable color masterbatch comprises the formula compositions in parts by weight: 30-80 parts of biodegradable polyester, 10-40 parts of a pigment, 10-30 parts of a filler, 0.5-3 parts of a compatilizer, 5-20 parts of a lubricant and 0.1-0.6 part of an anti-oxidant. The fully-biodegradable color masterbatch is obtained through melt blending, extrusion, strip pulling and pelletizing by employing a double screw extruder. The fully-biodegradable color masterbatch is completely biodegradable, good in processing performance and good in dispersing effect in a matrix, and has extremely good compatibility with a polyester matrix even a masterbatch carrier and a biodegradable polyester matrix are different polyesters. The masterbatch gives play to extremely good coloring effect on a product when being applied to a biodegradable polyester.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and relates to a universal fully biodegradable color masterbatch and a preparation method thereof. Background technique

[0002] The use of plastic materials has penetrated into all areas of people's lives, and is widely used as food packaging, electronic and electrical product packaging, shopping bags, garbage bags and disposable injection molding products. The raw materials of traditional plastic materials such as polypropylene (PP), polyethylene (PE), polystyrene (PS) are petroleum, which are difficult to degrade when discarded in nature after use, causing great harm to the environment. With the depletion of petroleum resources and the continuous enhancement of people's awareness of environmental protection, the development of fully degradable, environmentally friendly polymer materials used in the field of films and disposable injection molding products has become the mainstream of ...
