Plant fiber master batch as well as preparation method and application thereof

Abstract

The invention discloses a plant fiber master batch as well as a preparation method and application thereof, plant fibers with a certain size are firstly treated in alkali liquor and then internally mixed with a thermoplastic elastomer with a specific melting temperature and a silane coupling agent at a relatively low temperature to prepare the plant fiber master batch, so that gas generation of the plant fibers is reduced; the plant fiber master batch is further used for preparing the plant fiber reinforced thermoplastic composite material, feeding is convenient, compatibility of the plant fiber master batch and a thermoplastic polymer matrix is good, and the prepared plant fiber reinforced thermoplastic composite material has good mechanical properties and low odor and can be applied to the fields of automotive interior materials, household appliance materials and the like.

Description

technical field [0001] The invention relates to the technical field of modified materials, more specifically, relates to a plant fiber masterbatch and its preparation method and application. Background technique [0002] Using plant fiber as the reinforcement of the polymer matrix to prepare thermoplastic composite materials, compared with synthetic fibers, the advantages of plant fibers are: degradable, environmentally friendly, carbon emission reduction, renewable, abundant sources, low cost, low density, and relatively High specific strength, less wear and tear on processing equipment, no skin irritation, less damage to workers, good heat and sound insulation properties, etc. Plant fiber reinforced thermoplastic composites have been widely used in transportation (automotive, railway passenger cars, aerospace), ships, sports products, construction industry, electronics industry, packaging and other fields. [0003] Although plant fiber reinforced thermoplastic composites ...
