Abstract

The invention provides nanometer complex particle, comprising aliphatic polyamide, inorganic nano material, mineral filler, and organic auxiliary agent. The invention also provides the preparing method, which is simple and easy control. The nanometer complex particle can be used for lamp body, lamp shade, finishing material and other outdoor lamp materials, and the materials have the obvious anti-photoageing, good weatherability and light environmental pollution.

Description

technical field [0001] The invention relates to a nanocomposite masterbatch, specifically, it is a nanocomposite masterbatch specially used for outdoor lamps prepared from aliphatic polyamide, inorganic nanomaterials, inorganic fillers and organic additives, and belongs to the field of outdoor lamp materials . Background technique [0002] Plastics are widely used outdoors because of their advantages such as light material, insulation, wear resistance, corrosion resistance, aesthetics, simple processing technology, and low cost. However, when plastics (belonging to polymer resins) are exposed to high-energy ultraviolet radiation for a long time in outdoor use, they will undergo photoaging and lead to degradation, and the degradation products will react with oxygen or other active components in the air, resulting in yellowing. Glossiness and physical and mechanical properties will be greatly reduced, which will eventually lead to a reduction in its actual service life [Zhou ...
