Blue red phosphorus flame retardance reinforced polyamide material

Abstract

The invention discloses a blue red phosphorus flame retardance reinforced polyamide material. The polyamide material contains the following raw compositions: polyamide resin, a reinforcing component,red phosphorus flame retardant, flame retardant synergist, pigment, a functional auxiliary agent and a disacidifying agent, wherein the functional auxiliary agent comprises components A and B; the component A is selected from a mixture of N, N-bis(2, 2, 6, 6- tetramethyl-4-piperidinyl)-1,3-phthalamide and a copper halide compound; the component B is selected from at least one of a cerium-containing compound, a zinc-containing compound and an aluminum-containing compound; and the pigment includes pigment blue, pigment black, pigment green, pigment yellow and pigment white. The blue red phosphorus flame retardance reinforced polyamide material provided by the invention has the advantages that the material has excellent moist heat resistance, laser marking property, clear laser marking effectand high contrast; the color stability can be well maintained; and excellent mechanical property and flame retardant property are maintained at the same time.

Description

technical field [0001] The invention relates to the field of red phosphorus flame-retardant polyamide materials, in particular to a blue red phosphorus flame-retardant reinforced polyamide material. Background technique [0002] The red phosphorus flame retardant reinforced polyamide material has the following significant advantages: less addition, high flame retardant efficiency, and the flame retardant system can maintain excellent mechanical properties; in addition, the red phosphorus flame retardant polyamide system has a higher CTI value, which is It is widely used in electrical switches, low-voltage circuit breakers, connection contactors, sockets and other fields. [0003] However, due to the red phosphorus's deep red limit, most of the products made of red phosphorus flame-retardant reinforced polyamide materials are formulated into dark colors such as black or deep red, and some electrical products such as the back seat of the wall are blue in color. The flame-reta...

Problems solved by technology

[0005] But at present, the application of laser marking in red phosphorus flame-retardant reinforced polyamide material electrical products is less. At the same time, the high-energy laser beam during the laser marking process will cause the red phosphorus flame retardant to undergo a chemical reaction, resulting in unclear effects of laser marking red phosphorus flame retardant nylon, showing a dark yellow or dark gray color. Formulated with blue or dark blue red phosphorus flame-retardant reinforced polyamide materials, the laser marking of red phosphorus flame-retardant nylon materials must be based on the premise of maintaining good color stability, and because different pigments can select different wavelengths of light in visible light Absorption, and the compatibility between various pigments and red phosphorus is inconsistent, resulting in blue red phosphorus flame-retardant reinforced polyamide materials are difficult to obtain high-definition laser marking
