Abstract

The invention provides good-surface high-impact PA (Polyamide) / POK (Polyketone) alloy and a preparation method thereof. A preparation raw material of the good-surface high-impact PA / POK alloy is prepared from the following components in parts by mass: 47.5 to 67.5 parts of PA, 10 to 15 parts of POK, 3 to 5 parts of a compatilizer, 25 to 35 parts of fiberglass, 1 to 2 parts of a staining compound,0.3 to 0.5 part of an antioxidant and 0.5 to 1.5 parts of a lubricant, wherein the PA is a mixture of PA66 resin and PA66 / 6 resin, and a mass ratio of the PA66 resin to the PA66 / 6 resin in the mixtureis (1.4 to 2.5):1. In a formula of the raw material of the good-surface high-impact PA / POK alloy provided by the invention, due to the introduction of a PA66 / 6 copolymer PA system, the defects that afiberglass enhanced product is relatively serious in surface fiber floating and fast in crystallization can be overcome, the surface effect can be improved to a large extent under the situation thatthe temperature-resistant advantage of PA66 is not reduced, and meanwhile, the impact strength of the alloy can also be increased under the matching use of the POK.

Description

technical field [0001] The invention relates to the field of polymer material processing, in particular to a good-surface, high-impact, warpage-resistant nylon / POK alloy and a preparation method thereof. Background technique [0002] Nylon, or polyamide (PA), is a class of polymer compounds containing amide groups in the main chain, and is the most widely used general-purpose engineering plastic. Because the main chain contains a large number of highly polar amide groups, forming a "hydrogen bond" effect, resulting in a substantial increase in the intermolecular binding force, so that nylon resin has excellent mechanical properties and can be widely used in industrial fields. Among them, PA66 is a typical representative of general-purpose nylon, and PA6 is the most widely used general-purpose nylon. It has higher strength and heat resistance than PA6, and is mainly used in the automotive and electrical fields. But at the same time, PA66 also has the disadvantages of high wa...
