Embodiment 1

[0011] Embodiment 1 provides a halogen-free anti-warping and deformation-reinforced high-temperature nylon, which is composed of the following components by weight: high-temperature nylon: 55%, high-temperature-resistant black matrix: 1.5%; halogen-free and alkali-free glass fiber: 23%; Halogen glass beads: 15%: toughening agent: 3%; coupling agent: 0.3%; other additives: 2.2%;

[0012] First, weigh the high-temperature nylon, high-temperature-resistant black masterbatch, halogen-free glass beads, toughening agent, coupling agent, and other additives according to the proportion and mix them in the mixer at low speed for 10 minutes. The mixer adopts low-speed mixing, stirring The gap between the leaves and the cylinder wall should be less than 0.5 cm, and the mixing effect of raw and auxiliary materials should be visually observed that the various particles and powders are basically uniform, without obvious agglomerates or agglomerations; the twin-screw extruder uses a 36 aspect...

Abstract

The invention relates to an organic high-polymer composite, in particular to halogen-free buckling deformation resistant reinforced high-temperature nylon and a preparation method thereof. The halogen-free buckling deformation resistant reinforced high-temperature nylon comprises the following components by weight percentage: 49.5 to 90 percent of high-temperature nylon, 1 to 35 percent of halogen-free and alkali-free glass fiber, 1 to 30 percent of halogen-free glass beads, 1 to 5 percent of flexibilizer, 0.1 to 0.4 percent of coupling agent, and 0.1 to 5.5 percent of other assistants. The halogen-free buckling deformation resistant reinforced high-temperature nylon and the preparation method thereof are halogen-free and environment-friendly, have the additional characteristic of good resistance to buckling deformation on the basis of maintaining good comprehensive mechanical performances, are more suitable for being used for producing workpieces which need to be assembled tightly, such as mask / shell and product frameworks, and are also convenient for producing and purchasing, thus improving the comprehensive competitiveness of products in all aspects.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, relates to a halogen-free anti-warping deformation reinforced high-temperature nylon and a preparation method thereof. Background technique [0002] At present, the use of plastics to replace metals in the automotive industry continues to expand internationally. Scientists around the world are actively looking for new high-performance thermoplastics through various experiments, which has also become an important part of companies' efforts to win more customers and expand market share. The development of glass fiber reinforced high temperature nylon made this possible. High temperature nylon can bring higher temperature performance to some parts. There is also a trend of replacing metal and thermosetting materials with high-temperature resistant nylon in the engine cases of new cars, as well as in the brakes and clutch components of cars. All of these will increase the ...
