Problems solved by technology

However, because the intake manifold generally has a three-dimensional structure, it is difficult to achieve one-time molding by ordinary injection molding technology, and it must be formed by blow molding technology. highly dependent on
The existing conventional materials that can be applied to blow molding are mainly ordinary plastics such as rubber elastomers, PP, HDPE, etc., which have great limitations in heat resistance and long-term aging resistance, and cannot meet the relevant requirements for materials for automobile engine intake pipes, so The application is quite limited, and it is impossible to realize the comprehensive plasticization of the piping around the engine

Abstract

The invention provides a composite material special for blow molding of a reinforced nylon air inlet pipe. The composite material comprises the following components in percentage by mass: 20-83 percent of main material, 3-10 percent of modifier, 3-35 percent of elastomer, 10-30 percent of enhancing filler and 1-5 percent of auxiliary agent. The composite material special for blow molding of the reinforced nylon air inlet pipe can be used in blow molded products of air inlet pipelines, oil paths or cooling system pipelines at the peripheries of automobile engines. The composite material contains the reinforcing filler; the strength and the high temperature resistance performance of the composite material are improved; and the composite material is rich and cheap in raw materials and is suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of special nylon materials for auto parts, in particular to a special composite material for reinforced nylon air intake pipe blow molding and a preparation method thereof. Background technique [0002] Lightweight is one of the development directions of the automobile industry. In order to save energy, reduce emissions, increase vehicle speed, and reduce costs, since the 1990s, functional parts made of plastics have been increasingly used in automobiles. The ease of molding of plastics has led to its increasing use in the manufacture of complex structural components such as engine intake manifolds and fuel tanks, thus playing an important role in promoting the advancement of automobile manufacturing technology. [0003] For a long time, most domestic engine intake pipes are made of aluminum alloy or stainless steel. In foreign countries, plastic intake pipes have been widely used. For example, plastic int...
