Halogen-free buckling deformation prevention glazed flame-retardant nylon 66 and manufacturing process thereof

Abstract

The invention relates to an organic polymer composite material, in particular to halogen-free buckling deformation prevention glazed flame-retardant nylon 66 and a manufacturing process thereof; the halogen-free buckling deformation prevention glazed flame-retardant nylon 66 is composed of the following ingredients by weight ratio: 45-70 percent of nylon 66, 5-20 percent of halogen-free retarding masterbatch, 2-6 percent of halogen-free auxiliary flame retardants, 1-30 percent of halogen-free glass beads, 1-5 percent of flexibilizer, 0.1-0.4 percent of coupling agent, 0.1-1 percent of antioxygen and 0.1-5.5 percent of other agents; the halogen-free buckling deformation prevention glazed flame-retardant nylon 66 and the manufacturing process thereof have the characteristics of good buckling deformation prevention performance and high lustrousness on the basis of keeping good comprehensive mechanical performance and fireproofing and flame-retardant performances, the flowability is good and the production procurement is convenient, thereby improving the competitiveness.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, relates to a halogen-free anti-warping deformation high-gloss flame-retardant nylon 66 and a preparation method thereof. Background technique [0002] Flame-retardant nylon 66 is one of the most widely used engineering plastics, and this type of material is widely used in various fields. 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 them, the requirement of halogen-free materials for electronic and electrical products is one of them. Therefore, it has caused serious 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...

Therefore, it has caused serious 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, the anti-warping nylon 66 material has been produced in the market, which has a series of shortcomings such as low strength, insufficient anti-warping effect, insufficient luster of the product appearance, and poor fluidity of the material.
