Problems solved by technology

[0002] Halogen-free flame retardants are mainly phosphorus compounds and metal hydroxide compounds. These two types of compounds do not volatilize and do not produce corrosive gases when burned. They are called non-disclosure flame retardants. Among the existing technologies, there are many developments and applications of halogen-free flame-retardant PA6, but at present, there are generally situations where the molding cycle is long or injection mold release is difficult, and there are relatively few researches and developments on rapid prototyping, and there are few public records. involves
In the injection molding process of the existing halogen-free flame-retardant PA6 materials, there are often situations such as mold sticking and mold release top deformation. The lengthening of the molding cycle reduces the production efficiency

Abstract

The invention relates to a rapidly-formed halogen-free flame-retardant PA6 composite material and a preparation method thereof. The rapidly-formed halogen-free flame-retardant PA6 composite material comprises the following raw materials in percentage by mass: 65-80% of PA6 resin; 15-25% of a phosphorus-nitrogen composite flame retardant; 3-5% of a synergistic flame retardant; 0.5-2% of a nucleating agent; 0.5 to 1% of an antioxidant; and 1-2% of a lubricant. The prepared rapid prototyping halogen-free flame-retardant PA6 composite material does not contain halogen, meets the green and environment-friendly requirements, has the characteristics of rapid prototyping, shortening of the injection molding period and the like, is especially suitable for injection molding of thin-wall plastic products, effectively shortens the molding period during injection molding of the material, and improves the production efficiency. Meanwhile, the physical property and the flame retardant property of the material are kept.
