Abstract

The invention discloses a special material for a composite glass fiber heat-insulation strip using high-fluidity high-temperature nylon resin as a matrix. The material comprises the following components: 72-77.5wt% of high-fluidity high-temperature nylon, 22-27.5wt% of glass fiber, 0.05-1wt% of a fiber treating agent, 0.1-2wt% of a coloring agent, 0.1-1wt% of an antioxidant, 0.05-1wt% of a plasticizer, 0.05-1wt% of a coupling agent and 0.1-1wt% of additives. The invention also discloses a polymerization method of high-fluidity high-temperature nylon and a preparation method of the special material for the heat-insulation strip. Since a melt of the high-temperature nylon adopted in the material has good fluidity so that the process is simple, the energy consumption can be reduced, the cost conservation is achieved, the added aid is protected from being decomposed at a high temperature to cause failure and meanwhile, the prepared special material for the heat-insulation strip has excellent performance, high strength and good dimensional stability and the excellent performance can be still maintained at large temperature difference.

Description

technical field

[0001] The invention relates to a heat-insulating strip material, in particular to a high-fluidity high-temperature polyamide heat-insulating strip special material and a preparation method thereof. Background technique

[0002] The heat insulation strip material is the core component of the strip heat insulation profile. It is not only a "broken bridge" on the heat transfer path in the aluminum profile, which can reduce the heat transfer in the aluminum profile; Structural connector, through which the connection of the three parts of the insulating profile becomes a whole and bears the load together. At present, the thermal insulation strip material of broken bridge aluminum alloy doors and windows is made of PA (polyamide, commonly known as nylon) as the base material and added with glass fiber for extrusion.

[0003] PA heat insulation strip material has the characteristics of high tensile strength (PA heat insulation strip material: ≥126N / mm), high therm...
