Problems solved by technology

Therefore, it has caused great troubles to many export enterprises in my country.
At the same time, since nylon 66 is a crystalline material, it is easy to generate large internal stress during molding, resulting in warping and deformation of the finished product
At present, there are anti-warping nylon 66 materials in the market that 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

[0009] Embodiment 1 provides a halogen-free high-gloss anti-warping deformation filled nylon 66, which is composed of the following components by weight: nylon 66: 53%, nylon 66 carrier high-pigment black masterbatch: 1.5%; talcum powder: 15%; Whiskers: 8%; Halogen-free glass beads: 18%; Toughener: 2%; Coupling agent: 0.3%; Other additives: 2.2%;

[0010] First weigh nylon 66, nylon 66 carrier high-pigment black masterbatch, halogen-free glass beads, toughening agent, coupling agent, and other additives according to the proportion, then mix in the mixer at low speed for 10 minutes, and the mixer adopts low speed For mixing, the gap between the stirring 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 aggregation; the twin-screw extruder uses a 36 aspect ratio and a medium-strength shear Screw co...

Abstract

The invention relates to an organic polymer composite material, in particular to a high-gloss anti-warp-distortion nylon 66 and a production process thereof. The high-gloss anti-warp-distortion nylon 66 consists of the following compositions in percentage by weight: 46.5 to 80 percent of nylon 66, 0 to 25 percent of talcpowder, 0 to 25 percent of whisker; 0 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 aids. By the production process, the halogen-free high-gloss anti-warp-distortion nylon 66 is halogen-free and environment-friendly, preserves good mechanical properties and has the characteristics of anti-warp-distortion performance, attractive appearance, small contraction, uniformity and high temperature resistance, the production and the procurement are convenient, so that the competiveness of the product is improved, and the halogen-free high-gloss anti-warp-distortion nylon 66 is suitable for producing workpieces such as face mask / shell which require tight fitting and attractive appearances.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, to a high-gloss anti-warping deformation nylon 66 and its manufacturing process. Background technique [0002] Nylon 66 is one of the most widely used engineering plastics. This kind of material is widely used in various fields and can be seen everywhere in industry and our daily life. At present, for various reasons, developed countries such as Europe / Japan have imposed various restrictions on foreign imports and set up a series of barriers, among which the requirement for halogen-free materials for electronic and electrical products is one of them. Therefore, it has caused great troubles to many export enterprises in our country. At the same time, since nylon 66 is a crystalline material, it is easy to generate large internal stress during molding, which will lead to warping and deformation of the finished product. At present, the anti-warping nylon 66 material in th...
