Problems solved by technology

[0003] At present, in the production of polyoxymethylene composite materials, most of the color masterbatches used are LLDPE, HDPE or PP as the carrier. These color masterbatches are not well compatible with POM, which will lead to the appearance of products in the injection molding process. Delamination and other issues, so the research and development personnel began to develop POM special color masterbatch
The special color masterbatches for POM on the market are single in performance and cannot meet the needs of production. Especially in the process of people using color masterbatches to produce products, it is easy to generate a large amount of charge, and the accumulated large amount of charge is easy to cause fire, and there is a potential Danger

Abstract

The invention involves a flame retardant anti -static POM -specific female granules and their preparation methods, which belongs to the field of polymer material technology.The female grains include the following raw materials according to the weight of the weight: 80 ~ 100 copies of the formaldehyde, 12 ~ 18 copies of nanomonians, 10 ~ 30 parts of electrical stone powder, 30 ~ 80 parts of color powder, zinc 12 ~ 12 ~ 12 ~ 12 ~ 12 ~25 copies, 1 ~ 8 parts of ethyl oxidation dulate, 1 ~ 5 parts of di methyl acetate, 5 ~ 8 parts of cyanal melamine, polytimononylin hyperfluoride ultra -fine powder 2 ~ 4share.The preparation method of the present invention is simple. When the coloring female grains are used in POM products, they have the advantages of high color stability, small color difference, and no layered phenomenon.The burning agent makes this product have good anti -static and flame retardant performance, which greatly increases the safety in the process of production and use.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant and antistatic POM special color masterbatch and a preparation method thereof. Background technique [0002] Polyoxymethylene, abbreviated as POM, is a thermoplastic crystalline polymer known as "super steel" or "sai steel", also known as polyoxymethylene. POM has the hardness, strength and rigidity similar to metal, and it has good self-lubrication, good fatigue resistance and elasticity in a wide range of temperature and humidity. In addition, it has good chemical resistance. character. Since its inception, POM has been widely used in electronics, machinery, instruments, daily light industry, automobiles, building materials, agriculture and other fields. [0003] At present, in the production of polyoxymethylene composite materials, most of the color masterbatches used are LLDPE, HDPE or PP as the carrier. These color masterbatches are ...
