Problems solved by technology

Due to the addition of a large number of additives, on the one hand, it affects the compatibility of products made of PA6, and the problem of material inhomogeneity is prone to occur. The strength is greatly reduced, so the application field of high impact resistance of nylon 6 is greatly limited

Abstract

The invention discloses long fiber reinforced nylon plastic and a preparation method thereof. The long fiber reinforced nylon plastic is prepared from the following components in parts by weight: 88-96 parts of PA6, 12-15 parts of long fibers, 5-8 parts of polyethylene glycol, 4-6 parts of oleic acid, 3-5 parts of maleic anhydride grafted polypropylene, 2-3 parts of 2-hydroxy-4-n-octyloxybenzophenone, 1.5-3 parts of ethylene bis stearamide and 1-2 parts of phenyl phosphate bis-oxiranylmethyl ester. The invention also provides the preparation method of the long fiber reinforced nylon plastic.

Description

technical field [0001] The invention belongs to the field of plastic materials, in particular to a long fiber reinforced nylon plastic and a preparation method thereof. Background technique [0002] Nylon 6 (PA6) is a translucent or opaque milky white particle with thermoplasticity, light weight, good toughness, chemical resistance and durability. It is generally used in auto parts, mechanical parts, electronic and electrical products, engineering accessories and consumer goods. [0003] Nylon 6 is a crystalline polymer with a high melting point. It has excellent mechanical properties, good molding conditions, and low friction. Although polyamide resin has many excellent properties, in order to improve the mechanical properties of PA6, it is often necessary to add various Modifier. In order to improve the impact resistance of PA6, it is mainly by adding an appropriate amount of glass fibers or inorganic fillers, and sometimes by adding synthetic rubber. Due to the additio...
