Abstract

The invention provides a preparation method of an inflaming-retarding nylon alloy material and belongs to the technical field of a high molecular material. The preparation method comprises the following steps of: weighing the following components in parts by weight: 62-68 parts of nylon 1010 resin, 28-34 parts of ethylene-octylene resin, 0.6-1.3 parts of coupling agent, 10-23 parts of fillers and 15-24 parts of fire retardant; adding the components into a high-speed mixing machine to be mixed; adding the following weighed components in parts by weight: 0.4-1.0 part of antioxidant, 31-40 parts of short glass fibers and 0.4-0.7 part of octadecanamide; continually mixing to obtain a granulating material; adding the obtained granulating material into a double-screw extruding machine to be melted and extruded; and controlling an extruding temperature of the double-screw extruding machine to obtain the inflaming-retarding nylon alloy material. The preparation method has the advantages that the tensile strength is more than 140 MPa, the flexural strength is more than 190 MPa, the impact strength of a cantilever beam notch is more than 29 kj / m<2>, the melt index is more than 21 g / 10 min, and the fire resistance is V-0 (UL-94-1.6 mm), so that the ideal fire resistance is represented and the brittleness is further eliminated.

Description

Technical field [0001] The present invention is a high -molecular material preparation technology field, which involves a method of preparation of flame -retardant nylon alloy materials. Background technique [0002] Nylon is a widely used engineering material that is used in machinery, electronics, electrical, military, transportation, etc., but because the nylon material is brittle, it restricts the expansion of its use to a certain extent.Ethylene-ethyne is recognized as an excellent elastic material. It is a good way to add it to the nylon material of the nylon and use reasonable preparation methods to make up for the brittleness of nylon.A beneficial attempt, the technical solution introduced below is based on the premise. Invention content [0003] The task of the present invention is to provide a method of preparing a flame retardant nylon alloy material. The nylon alloy material obtained by this method helps improve the flame retardability and conducive to the crispness....
