Problems solved by technology

[0006] It can be seen that although the above patents are related to the odor of the nylon 6 composition, their main goal is not to reduce the odor of the nylon 6 composition, and because these methods improve the nylon 6 composition by adding adsorptive substances or reactive substances The problem of high odor often leads to different degrees of reduction in the performance of nylon 6 compositions and an increase in production costs

Abstract

The invention introduces a low-smell nylon 6 composition, whose components comprises nylon 6 resin, compatilizer, filler, lubricant polysiloxane and additive. The invention is characterized in that the compatilizer of the composition is polyolefin and grafted copolymer of unsaturated acid and anhydride; the lubricant is super high molecular weight polysiloxane. The mixing amount (in part by weight) of the components respectively is: nylon 6 resin 40 to 97, the compatilizer 1 to 20, the filler 1 to 40, the lubricant 0.5 to 5, the other additives 0.3 to 2. The way to reduce the smell of the nylon 6 composition uses the modified technique with low cost to reduce the smell of the nylon 6 composition with simple operation, and meanwhile increases the performance of the nylon 6 composition.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a low-odor nylon 6 composition and a preparation method thereof. technical background [0002] Nylon 6 resin is a general-purpose engineering plastic with excellent comprehensive properties. It has excellent mechanical properties and advantages such as wear resistance, solvent resistance, and oil resistance. It is widely used in various industries. It is becoming more and more widespread and has received great attention from the majority of users. Since its industrialization more than 50 years ago, its application fields have continued to expand, and it has become the main material for the automotive industry and electronic appliances, and has developed into the world's largest engineering plastic. Although nylon material has many advantages, due to the volatilization of residual monomers in the polymerization process during the molding process, the odor emitted is relatively larg...
