Problems solved by technology

However, because it is easy to cause orientation and anisotropy, it is easy to generate large internal stress during molding, which will lead to warping and deformation of the finished product
At present, there are anti-warping high-temperatu

Example Embodiment

[0010] The first embodiment provides a halogen-free high-gloss anti-warpage deformation filled high-temperature nylon raw material, which is composed of the following ingredients in a weight ratio: high-temperature nylon: 55%, high-temperature black masterbatch: 1.5%; talc: 15%; whiskers : 8%; halogen-free glass beads: 15%: toughening agent: 3%; coupling agent: 0.3%; other additives: 2.2%;

[0011] 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 proportions, and then mix in the mixer at low speed for 10 minutes. The mixer uses low speed mixing and stirring The gap between the leaf and the barrel wall should be less than 0.5 cm. The mixing effect of the raw and auxiliary materials should be visually uniform, with no obvious agglomeration or agglomeration; the twin-screw extruder uses a 36 L / D, medium-strength shear screw combination, Set the rotati...

Abstract

The invention relates to an organic polymer composite material, in particular to a manufacture process of halogen-free high-gloss buckling deformation resisting nylon which comprises the following ingredients by weight: 49.5 to 90 percent of high-temperature nylon, 0 to 25 percent of talcum powder, 0 to 25 percent of whisker, 0 to 30 percent of halogen-free glass microspheres, 1 to 5 percent of flexibilizer, 0.1 to 0.4 percent of coupling agent and 0.1 to 5.5 percent of other additives. According to the halogen-free high-gloss buckling deformation resisting nylon and the manufacture process thereof which are provided by the invention, the environment is protected; halogen is avoided; the characteristics of high buckling deformation resistance and beautiful and high-gloss appearance are further achieved on the basis that the comprehensive mechanical property is maintained well; and the production and the purchase are convenient. Therefore, the competitiveness is improved; and the requirements on production of workpieces such as face masks and housings which are required to be assembled tightly and be beautiful and fire-resistant can be met better.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, relates to a production process of a halogen-free high-gloss anti-warping deformation nylon. Background technique [0002] At present, the use of plastics to replace metals in industry is expanding. Scientists from all over the world are actively looking for new high-performance thermoplastics through various experiments. The development of high temperature nylons made this possible. High temperature nylon can bring higher temperature performance to some parts. This material can withstand continuous high temperatures of 180°C, has excellent long-term and short-term thermal properties, can withstand the high temperatures generated by infrared (IR) reflow ovens used in lead-free soldering processes, has excellent mechanical strength, and is resistant to humidity. Provides the same strength and toughness in the environment, excellent chemical resistance, excellent electri...
