Abstract

The invention discloses a soft nonwoven master batch. The master batch is characterized in that the master batch comprises, by weight, 75-85 parts of a carrier, 14-24 parts of additives and 0.3-0.9 part of an active assistant, the carrier is a polypropylene homopolymer, the additives are oleamide and erucamide, and the active assistant is one or two of di-tert-butyl peroxide and dibenzoyl peroxide. A preparation method of the master batch comprises the following steps: proportioning all above components according to corresponding weight parts, heating and mixing erucamide powder and the activeassistant in a high-speed mixer in advance, adding the obtained mixture and other components into a co-rotating twin-screw extruder, and blending, extruding, drawing and pelletizing the finally obtained mixture to obtain the soft nonwoven master batch. The soft nonwoven master batch prepared in the invention allows the soft components to quickly and stably precipitate and achieves a good softening effect, so the influences brought by the environment and the like are reduced, and the softness of the product can be ensured without increasing the cost of raw materials.

Description

technical field [0001] The invention relates to a master batch and a preparation method thereof, in particular to a soft non-woven fabric master batch and a preparation method thereof. Background technique [0002] In the preparation process of non-woven fabrics, polypropylene is spun and then pressed into non-woven fabrics. The conventionally produced non-woven fabrics have rough surfaces, hard handles, and low comfort. In order to increase the softness and feel of non-woven fabrics, it is necessary to add soft masterbatches to polypropylene. The active ingredients of soft masterbatches currently used in non-woven fabrics are mainly divided into silicones and fatty amides. [0003] Silicone molecular polymer raw materials are easy to get and the price is low, but the compatibility with resin materials is poor. It needs to be modified or added with a dispersant to improve its dispersion in the resin, which increases the cost and production complexity. . [0004] There are ...
