Preparation method for anti-abrasion nylon heat insulation strip for bridge-cut-off aluminum doors and windows

Abstract

The invention discloses an anti-wear nylon heat insulation strip for bridge-cut-off aluminum doors and windows. The anti-wear nylon heat insulation strip is prepared by performing mixed melting on resin particles, nylon particles, heat insulation fibers, organic fluorine epoxy particles, an aluminate coupling agent, a dispersing agent, a nucleating agent and an antioxidant are mixed according to amass ratio of 20 to 20 to 10 to 12 to 5 to 1 to 0.5 to 0.5 and then extruding a product into a die for modeling. The invention further discloses a preparation method for the anti-abrasion nylon heatinsulation strip for the bridge-cut-off aluminum doors and windows. The preparation method comprises the following steps that 1, the resin particles, the nylon particles, the heat insulation fibers, the organic fluorine epoxy particles, the aluminate coupling agent, the dispersing agent, the nucleating agent and the antioxidant are mixed; and 2, heating work is performed on the uniformly mixed rawmaterials so as to melt the raw materials. For the anti-wear nylon heat insulation strip and the preparation method disclosed by the invention, a specially-made feeding device is adopted, the interior of a rolling shaft is hollow, a second straight plate is interconnected with the rolling shaft through a connecting shaft, and the situation that cooling liquid in a water storage tank in the secondstraight plate flows into the rolling shaft subsequently is facilitated.

Description

technical field [0001] The invention belongs to the field of heat-insulation strip processing, and in particular relates to a preparation method of an anti-wear nylon heat-insulation strip for broken bridge aluminum doors and windows. Background technique [0002] The heat insulation strip is mainly a structural connector for reducing heat transfer in the profile. It is a composite material made by mechanical rolling and cannot be replaced separately. During the processing of the heat insulation strip, it needs to be mixed , hot-melt and extrusion processes, and the overall performance of the heat-insulating strip can be produced according to different raw materials. The heat-insulating strip can be used in various equipment and products, including for bridge-breaking aluminum On the doors and windows.

AI Technical Summary

Problems solved by technology

[0003] (1) During the processing and production of nylon heat insulation strips, after the nylon heat insulation strips are extruded through the mold, the nylon heat insulation strips will be removed, and thus need to be transported smoothly through the feeding device, but due to the nylon heat insulation After the strip is extruded, it has a certain temperature, which will easily cause the nylon heat insulation strip itself to wear out in the process of performing other processes on the nylon heat insulation strip;

[0004] (2) Using other cooling devices will increase the working steps of the overall device, thereby increasing the volume of the entire production device, and at the same time will increase the work of energy consumption during the processing and production of nylon heat insulation strips, which is not conducive to the overall energy saving effect
