Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Glass beads are glass (or ceramic) spheres with a diameter ranging from a few microns to several millimeters. There are solid, hollow, and porous glass beads. They have good optical properties, spherical lens characteristics, strong impact resistance, and rolling. Good thermal conductivity, low thermal conductivity, light weight, etc., have been widely used in urban traffic signs, car license plates, retroreflective curtains, injection technology, filling materials, insulation materials and other fields.

Abstract

The invention discloses a preparation method and a rheological property test method of a reinforced toughened nylon 11 ternary composite material. The reinforced toughened nylon 11 ternary composite material is a PA11/HGB/POE-g-MAH ternary composite material. The preparation method comprises the following steps of continuously baking PA11 in a vacuum oven at a temperature of 80 DEG C for more than 12h, then accurately weighing HGB according to requirements, adding the weighed HGB and the PA11 into a silane coupling agent dissolved by ethanol, uniformly stirring by a glass rod, drying in air for next use, and carrying out extrusion granulation of the PA11-treated HGB and POE-g-MAH by a double-screw extruder at a temperature of 200 to 240 DEG C at a screw rotating speed of 90rpm. The PA11/HGB/POE-g-MAH ternary composite material is prepared by a melt blending method. The preparation method realizes influence caused by POE-g-MAH content on composite material rheological properties and lays a solid foundation for preparation of nylon 11 composite materials having better performances.

Description

technical field [0001] The invention relates to the preparation and rheological performance test of a reinforced and toughened nylon 11 ternary composite material, in particular to the research and rheological performance test of a PA11 / HGB / POE-g-MAH ternary 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 expan...
