Problems solved by technology

Therefore, it has caused serious troubles to many export enterprises in my country.
At the same time, since nylon 6 is a crystalline material, it is easy to generate large internal stress during molding, resulting in warping and deformation of the finished product
[0003] At present, there are anti-warping nylon 6 materials in the market, which use talcum powder to prevent warping, which has a series of disadvantages such as low strength, insufficient anti-warping effect, affecting the appearance of the product, and poor fluidity of the material.

Embodiment 1

[0010] Embodiment 1 provides a halogen-free high-gloss anti-warping deformation filled nylon 6, which is composed of the following components by weight: nylon 6: 48%, nylon 6 carrier high-pigment black masterbatch: 1.5%; talcum powder: 15%; Whiskers: 8%; Halogen-free glass beads: 22%; Toughener: 3%; Coupling agent: 0.3%; Other additives: 2.2%;

[0011] Dry nylon 6 first, and then weigh the dried nylon 6, nylon 6 carrier high-pigment black masterbatch, halogen-free glass beads, toughening agent, coupling agent, and other additives in the mixer according to the proportion Mix at low speed for 10 minutes, the mixer adopts low speed mixing, the gap between the mixing blade and the cylinder wall should be less than 0.5 cm, the mixing effect of raw and auxiliary materials should be visually observed that the various particles and powders are basically uniform, and there is no obvious agglomerate or agglomeration; twin-screw extruder Use 36 length-to-diameter ratio, medium-strength s...

Abstract

The invention relates to an organic polymer composite material, in particular to halogen-free buckling deformation resisting filling nylon 6 and a manufacture process of thereof. The halogen-free buckling deformation resisting filling nylon 6 comprises the following ingredients by weight: 45 to 70 percent of nylon 6, 1 to 25 percent of talcum powder, 1 to 25 percent of whisker, 1 to 40 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 filling nylon 6 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, high-gloss appearance, and low and uniform shrinkage ratio 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 favorable in appearance can be met better.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a halogen-free anti-warping deformation filled nylon 6 and a manufacturing process thereof. Background technique [0002] Nylon 6 is one of the most widely used engineering plastics. Its amide group is polar and has a strong hydrogen bond in its structure, which makes nylon 6 have a high melting point and good physical and mechanical properties. And wear resistance and self-lubricating properties, these comprehensive characteristics are not available in other plastics. However, the heat distortion temperature of pure nylon 6 is low, the water absorption is high, the impact strength before water absorption is low, the rigidity drops sharply after water absorption, and the size is unstable, which limits the application of nylon 6 and further reduces the downstream industry. Material selection for design engineers. Therefore, research on compound modificatio...
