Anti-electrostatic flame-retardant PA (polyamide) color master batch and preparation method thereof

Abstract

The invention discloses an anti-electrostatic flame-retardant PA (polyamide) color master batch. The anti-electrostatic flame-retardant PA color master batch is prepared from the following raw materials in parts by weight: 50 to 70 parts of PA, 25 to 40 parts of inorganic pigment, 20 to 30 parts of fiber, 4 to 6 parts of composite anti-electrostatic agent, 3 to 5 parts of composite dispersant, 6 to 8 parts of magnesium hydroxide flame-retardant agent, and 1 to 2 parts of compatilizer. The anti-electrostatic flame-retardant PA color master batch has the advantages that the cost is low, the preparation technology is simple, and the anti-electrostatic property and flame-retardant property are excellent; when the anti-electrostatic flame-retardant PA color master batch is used for coloring thePA product, the fire risk of the PA product is reduced, the safety hidden hazards are reduced, and the fire propagation speed is effectively inhibited when a fire accident occurs, so as to provide the valuable time for fire extinguishing, and protect the property safety and body safety of people.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antistatic flame retardant PA color masterbatch and a preparation method thereof. Background technique [0002] Polyamide (PA) is a widely used engineering plastic resin. Due to its unique low specific gravity, high tensile strength, wear resistance, good self-lubricating property, excellent impact toughness, and both rigidity and flexibility, it has won people's attention. In addition, it is easy to process, high in efficiency, and light in specific gravity. It can be processed into various These products are used to replace metals and are widely used in the automotive and transportation industries. Masterbatch coloring is the most commonly used plastic coloring method today. [0003] At present, domestic masterbatch products have a single structure and incomplete varieties, and general-purpose products account for a large proportion. When plastics nee...

Problems solved by technology

[0003] At present, domestic masterbatch products have a single structure and incomplete varieties, and general-purpose products account for a large proportion. When plastics need to be colored, single-color masterbatches are used for coloring. When antistatic performance is required, antistatic masterbatches are added. When flame retardant performance is required Add flame retardant masterbatch

The method of adding a single masterbatch makes it necessary to add a variety of color masterbatches with different functions when the comprehensive performance of the carrier resin is high, thus consuming a large amount of carrier resin and resulting in the consumption of antioxidants during processing Due to the disadvantages of high volume, many components in downstream molding processing, and complicated processes, the future masterbatch will continue to develop in the direction of multi-functionality, high color content and high technology content.

[0004] PA is widely used in the automobile and transportation industry, and now traffic accidents occur frequently, and vehicles are prone to fire. If the fire is not extinguished in time, it will not only cause property loss, but also easily cause injury to the car owner, threatening the personal safety of the car owner.
