Abstract

The invention provides a method for preparing nanometer heat-insulation composite material, which mainly comprises nylon PA66, long alkali-free glass fiber yarn, short alkali-free glass fiber, nano-titanium dioxide (TiO2) and nano-montmorillonite; the method adopts high-temperature (150 DEG C) activation technology to activate the mixture of the nano-titanium dioxide (TiO2) and the nano-montmorillonite, adds small amount of nano-composite additives when in preparation, and adopts the long alkali-free glass fiber yarn, the short alkali-free glass fiber, a plasticizer and a coupling agent for stage addition; and as a special extrusion material, the composite material can achieve the effects of high tensile strength, high rigidity, stable molding, etc.

Description

technical field [0001] The invention relates to a method for preparing heat-insulating composite materials, in particular to a method for preparing nano-heat-insulating composite materials composed of nylon PA66, nano-titanium dioxide, montmorillonite and the like. Background technique [0002] Nylon PA is one of the important varieties of polyamide. Polyamide is the earliest variety in engineering plastics. Its current output ranks first in engineering plastics. Nylon PA66 is one of the most widely used brands in polyamide. It has polyamide varieties. Among the main features, it has excellent mechanical properties, self-lubricating properties, friction resistance, heat resistance, weather resistance and electrical properties. After nylon PA66 is reinforced with glass fiber, its thermal deformation temperature can reach above 250°C. Water absorption is also a major feature of polyamide, which affects the dimensional stability of parts to a certain extent and limits its appl...
