Problems solved by technology

[0004] For the three-dimensional blow molding process with more advantages, the requirements for the melt strength of the polyamide material or its composition are higher, otherwise it is easy to cause uneven wall thickness of the blown pipe body or fail to meet the wall thickness requirements
This kind of parts also requires high temperature resistance, and it is difficult to use traditional impact-resistant modified nylon materials for long-term use at 160 °C.

Abstract

The invention provides an automotive pipeline three-dimensional blow molding glass fiber reinforced polyamide 6 composition and a preparation method thereof. The automotive pipeline three-dimensionalblow molding glass fiber reinforced polyamide 6 composition comprises the following components in parts by weight: 25-83 parts of high-viscosity polyamide 6, 5-20 parts of an impact modifier, 10-40 parts of chopped glass fibers, 1-10 parts of a chain extender and 1-5 parts of other promoters. The relative viscosity of the high-viscosity polyamide 6 in 98wt% of concentrated sulfuric acid at the temperature of 25 DEG C is 3.4-4.0. The automotive pipeline three-dimensional blow molding glass fiber reinforced polyamide 6 composition has high melt strength, high mechanical property, excellent ageing resistance and good three-dimensional blow molding performance.

Description

technical field [0001] The invention belongs to the field of polymer materials and their molding processing, and in particular relates to a three-dimensional blow-molded glass fiber reinforced polyamide 6 composition for automobile pipelines and a preparation method thereof. Background technique [0002] With excellent mechanical strength, chemical resistance and high temperature resistance, polyamide material has become the most suitable engineering plastic for application around the engine. With the rapid development of automobile lightweight, more metal parts around automobile engines are replaced by polyamide materials, such as intercooler inlet pipes, air filter outlet pipes and other traditional metal pipes are replaced by polyamide materials. There are several processes for processing and forming similar pipes: injection molding and then welding into pipes; two-dimensional blow molding, pipes with complex structures need to be equipped with accessories such as pipe jo...
