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 relates to an antiflaming and antistatic POM dedicated color master batch and a preparation method thereof, and belongs to the technical field of high polymer materials. The color master batch comprises the following raw materials in parts by weight: 80-100 parts of polyformaldehyde, 12-18 parts of nano-montmorillonite, 10-30 parts of electric mountain flour, 30-80 parts of toner, 12-25 parts of zinc stearate, 1-8 parts of ethoxylation dodecyl amine, 1-5 parts of dimethyl dimercaptoacetic acid isooctyl ester tin, 5-8 parts of cyanuric acid melamine and 2-4 parts of teflon ultrafine powder. According to the invention, the preparation method is simple, and the prepared color master batch has the advantages of high color stability, less aberration and no stratification when being applied to coloring of POM products; in addition, as antistat and halogen-free flame retardant are added into the raw materials, the antiflaming and antistatic POM dedicated color master batch has excellent anti-static function and flame retardant property, and safety during the production and using process is greatly increased.

Description

Technical field [0001] The present invention is a high -molecular material technology field, which involves a special color mother granules and their preparation methods for flame retardant POM. Background technique [0002] Polytealdehyde, an English abbreviation as POM, is a thermoplastic crystalline polymer, known as "ultra -steel" or "Saigang", also known as polyoxyama.POM has the hardness, strength and steel of similar metals. It has good self -lubricating, good fatigue resistance and elasticity in a very wide temperature and humidity range. In addition, it also has good chemical resistanceCharacterity.Since its inception, POM has been widely used in electronics, machinery, instrumentation, daily light industry, automotive, building materials, agriculture and other fields. [0003] At present, when the composite formaldehyde composite material is produced, most of the color mother used in the color mother with LLDPE, HDPE, or PP is the color mother.Layers and other problems,...
