Problems solved by technology

The nucleating effect of the organic nucleating agent is obvious, but the price is relatively high, and when its added amount reaches a certain value, the rigidity of nylon remains basically unchanged, that is, the mechanical properties will not be further improved with the increase of the added amount.
Inorganic nucleating agents affect the transparency and surface gloss of nylon products, and their application in transparent materials is limited

Abstract

The invention discloses a preparation method of a nylon nucleating agent, a prepared nylon nucleating agent and an application. The preparation method comprises the following steps: dissolving a benzoate nucleating agent in water to serve as an aqueous phase, using a light stabilizer as an oil phase, uniformly mixing the aqueous phase and the oil phase with a cosurfactant and a surfactant to form microemulsion. The nylon nucleating agent prepared by the preparation method is applied in modified nylon resin, and counted by 100 parts by weight of nylon resin, the use amount of the nucleating agent is 0.01-10 parts by weight. The nylon nucleating agent has the advantages of small use amount, good effect, low processing cost and simple preparation process, thereby being an ideal nylon resin nucleating agent. Meanwhile, the light stabilizer serving as the oil phase is synchronously added to not only help the nucleating agent to disperse, but also can improve the ageing resistance of the nucleating agent.

Description

technical field [0001] The invention relates to the field of nylon, and more specifically, relates to a preparation method of a nylon nucleating agent, a nucleating agent prepared therefrom and an application thereof. Background technique [0002] Nylon (Nylon), Chinese name polyamide, English name Polyamide (referred to as PA), is a general term for thermoplastic resins containing repeated amide groups -[NHCO]- on the main molecular chain. Nylon, as the most important engineering plastic, is used in almost every field and is the most widely used variety among the five major engineering plastics. In order to better meet the requirements of applications and other aspects, people continue to study various methods to improve the performance of nylon. Among them, improving the mechanical properties of nylon products by adding nucleating agents is one of the simple and effective modification methods to realize high performance nylon resins. [0003] At present, nylon nucleating...
