Abstract

The invention discloses a complexing type nylon nucleating agent and a preparation method thereof, and also provides a nylon compound containing the nylon nucleating agent, and a preparation method thereof. Carbonyl groups in polyamide 22 react with calcium ions in long-carbon-chain fatty acid calcium salt at a high temperature to generate a complex, so the hydrogen bond acting force between molecules of the nucleating agent is reduced, the nucleating agent does not agglomerate in a nylon resin system, and the dispersity is better, thereby the nucleating points are increased, the nucleating efficiency is increased, the crystallization temperature is increased, the crystallinity is increased, and the rigidity, toughness, heat resistance and transparency of a nylon product are improved. Theproblems that the single variety of nylon 22 (P22), calcium monophosphate (CaV102), inorganic filler and the like which are commercially available in the prior art is poor in dispersity and cannot beobtained in crystallization, lubrication and demolding at the same time are solved.

Description

technical field [0001] The invention belongs to the technical field of nylon nucleating agents, and in particular relates to a complex type nylon nucleating agent and a preparation method, as well as a nylon compound containing the nylon nucleating agent and a preparation method. Background technique [0002] Nylon is one of the five general-purpose engineering plastics with the largest production and consumption. It has many advantages such as high mechanical strength, heat resistance, low friction coefficient, self-lubrication, oil resistance, and weather resistance. It is widely used in automobiles, electronics, household consumer goods, Household appliances and other fields. In the production process of many nylon injection molded parts, there are generally problems such as slow crystallization rate and low crystallinity, and the resulting defects such as long production cycle, poor mold release performance, low modulus, and poor heat resistance restrict nylon Expansion...
