Embodiment 1-4

[0035] The preparation method of embodiment 1-4:

[0036] Step 1. Weigh PA6 resin powder and MCA flame retardant according to the ratio in Table 1, and put them into a high-speed mixer at a speed of 600r / min, mix for 2 minutes, mix well and evenly to form a flame retardant powder package, and set aside;

[0037] Step 2. Weigh the deodorant, calcium stearate and antioxidant 1098 according to the ratio in Table 1, and put them into a low-speed mixer at a speed of 100r / min, mix for 5min, mix well and form an additive package, and set aside ;

[0038] Step 3. Weigh the PA66 resin slices according to the ratio in Table 1, and feed the PA66 resin slices and the additive package obtained in step 2 from the main feeding port of the twin-screw extruder through weight loss weighing; The obtained flame retardant powder package is metered and fed from the side feeding port of the twin-screw extruder through a weight loss scale; the vacuum number of the twin-screw extruder is double vacuu...

Abstract

A low-odor low-precipitation flame-retardant polyamide material, its preparation method and application are provided. The low-odor low-precipitation flame-retardant polyamide material comprises the following raw materials in percentage by weight: 84.5-92% of polyamide, 7-13% of a flame retardant, 0.5-1.5% of a deodorant, 0.3-0.5% of a lubricant and 0.2-0.5% of an antioxidant, wherein the flame retardant is melamine cyanurate flame retardant; the deodorant is a composition of an organic zinc salt and a silica-alumina molecular sieve; the organic zinc salt is a reactive organic zinc salt with long carbon chain, the particle size of silica-alumina molecular sieve is <= 15 Mum. The low-odor low-precipitation flame-retardant polyamide material provided by the invention not only has good flame retardancy, but also has low flame retardant small molecule precipitation, less injection mold deposition problem and product odor problem. The low-odor low-precipitation flame-retardant polyamide material can be applied to the automotive electronic and electrical field which requires high odor grade of the material.

Description

technical field [0001] The invention relates to an MCA flame-retardant polyamide material, in particular to a flame-retardant polyamide material with low odor and low precipitation, its preparation method and application. Background technique [0002] Polyamide (nylon, PA) is one of the five major engineering plastics with large output, variety and wide application. Nylon has high mechanical strength, high softening point, heat resistance, wear resistance, oil resistance, weak acid resistance, alkali resistance, general organic solvent resistance, electrical insulation and self-extinguishing properties. Nylon materials are widely used in the automotive industry, electrical and electronic industries, transportation, machinery, aerospace and other fields. Among them, the application of flame-retardant nylon materials in automotive electronics and electrical fields requires flame retardancy, environmental protection and health. [0003] With the continuous improvement of envi...
