Abstract

The invention discloses a preparation method and a test method of a composite material modified by nylon 11-based hollow glass bead. The preparation method comprises the steps of firstly putting nylon 11 and hollow glass beads into an oven at 80 DEG C and 0.09 MPa of the pressure of a vacuum pump to be dried for 12 hours in vacuum; respectively proportioning the nylon 11 and the hollow glass beads according to the required volume required in the formula; preparing materials by an extruder; drying the extruded materials; and injecting the materials to be formed. The test method comprises the steps of filling the nylon 11 with the hollow glass beads to be modified, extruding, pelletizing and preparing the composite material into a standard sample in a molten state by a double-screw extruder, and then testing various kinds of mechanical properties and the crystallization behavior of the sample. By analyzing the results, the influence of the glass beads of different content on the mechanical property and the crystallization behavior of the sample can be achieved, and the nylon 11-based modified composite material with better performance can be prepared.

Description

technical field [0001] The invention relates to the research and performance test of a nylon 11-based hollow glass microsphere modified composite material, in particular to the research and performance test of a nylon 11 / hollow glass microsphere composite material. Background technique [0002] With the rapid development of society and science and technology, the performance of a single material can no longer meet the growing situation, and high performance, multifunctionality and compounding have become the inevitable trend of material development. Compared with other polyamide materials, nylon 11 has the advantages of low water absorption, good oil resistance, low temperature resistance, good elastic memory effect, good stress crack resistance, and easy processing. However, the performance of pure nylon 11 can no longer meet the special requirements of various products for material performance, and its relatively high market price also limits the further expansion of its a...
