Toughening agent with core-shell structure as well as preparation method and application of toughening agent

Abstract

The invention discloses a core-shell structure flexibilizer as well as a preparation method and application thereof, and belongs to the field of high polymer materials. The toughening agent disclosed by the invention is of a three-layer core-shell structure comprising an inner core, a middle layer and an outer layer, the inner core is prepared from the following raw materials: sepiolite, tris (2-hydroxyethyl) isocyanurate and methyl ethyl ketone peroxide; the preparation raw materials of the middle layer comprise styrene, cyclohexanone oxide and hydroxyl-terminated butadiene; the outer layer is prepared from the following raw materials: N, N-dimethylaniline, norbornene-5, 6-cis-dicarboxylic anhydride and xylene. The toughening agent comprises a three-layer core-shell structure and has good bonding force with the polydicyclopentadiene resin, and the rigid core-shell structure provides good toughness for the resin and maintains the rigidity of the resin. When the toughening agent is applied to modification of a polydicyclopentadiene resin material, the mechanical property of the material is obviously improved.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a toughening agent with a core-shell structure and a preparation method and application thereof. Background technique [0002] Polydicyclopentadiene is a new type of high-performance engineering plastic, which is formed by ring-opening metathesis of cyclopentadiene. It has excellent mechanical properties, electrical properties, corrosion resistance and easy decoration properties. It has become a polymer Research hotspots in the field of materials. The material can be flexibly designed according to the structure, so it can be used in a wide range of fields, including automobiles, sports equipment, medical equipment, etc. Although the overall performance of polydicyclopentadiene is better than that of common engineering plastics, with the expansion of its application range, the performance requirements for materials are gradually increasing, and the application of this...

AI Technical Summary

Problems solved by technology

Polydicyclopentadiene is usually toughened and modified by adding rubber and elastomers. When this type of modification method is toughened, part of the strength and heat resistance must be sacrificed, thus greatly reducing the mechanical properties of polydicyclopentadiene materials.
