Multicolor red phosphorus flame-retardant nylon composition and preparation method thereof

Abstract

The invention discloses a multicolor red phosphorus flame-retardant nylon composition. The multicolor red phosphorus flame-retardant nylon composition is prepared from, by weight, 40%-70% of polyamide, 5%-20% of a red phosphorus flame retardant, 10%-35% of an enhanced component, 0.2%-5% of pigments, 0-3% of 4,4'-bismaleimide diphenylmethane, 0-3% of triallyl isocyanurate and 0.2%-3% of an auxiliary. According to the multicolor red phosphorus flame-retardant nylon composition, by adding the pigments, the multicolor red phosphorus flame-retardant composition can be supplied, and the current situation that an existing red phosphorus flame-retardant composition is single in color is changed; meanwhile, the specific weight percentage combination is adopted, therefore, the good flame retardant property, mechanical property and thermal property and multiple prepared colors are achieved, and the composition is mainly applied to electronic and electric industry and has the wide application prospect. The invention further provides a preparation method of the multicolor red phosphorus flame-retardant nylon composition, the preparation method can be achieved by adopting an existing double-screw extruder, preparation is easy, and industrialized production and implementation are easy to achieve.

Description

technical field [0001] The invention relates to the field of red phosphorus flame-retardant nylon materials, in particular to a multi-color red phosphorus flame-retardant nylon composition and a preparation method thereof. Background technique [0002] Due to its outstanding advantages in mechanical properties, thermal properties and chemical properties, nylon has become the base resin with the largest output, most varieties, widest uses and excellent comprehensive properties among the five general engineering projects. With the rapid development of the electrical and electronic industry, the use environment faced by nylon is becoming more and more harsh, so the requirements for the mechanical properties, flame retardant properties, thermal properties, electrical properties and other aspects of nylon compositions are further increased. At present, most of the AC contactor bases, bases, coil skeletons, wall switch back seats, boat switch bases, bases and other plastic product...
