Problems solved by technology

The existing organophosphate series nucleating agents are mainly metal salts, represented by the products of Japan Asahi Denka Corporation, which have experienced three generations of products, namely NA-10, NA-11, NA-21, in polypropylene The dispersibility of the resin is relatively poor, and the general recommended dosage is about 0.3% of the base resin

Abstract

The invention discloses an organic ammonium phosphate nucleating agent for polypropylene transparency and a preparation method of the organic ammonium phosphate nucleating agent. The molecular formula of the organic ammonium phosphate nucleating agent is shown in the description, wherein R1, R2, R3 and R4 are all hydrogen atoms or C1-C4 alkyl or branched alkyl; R1, R2, R3 and R4 are completely the same, completely different or partly same. The organic ammonium phosphate can be used as a nucleating agent for polypropylene transparency and has the advantages of low melting temperature, good dispersing effect, high nucleating efficiency and significant antireflection effect. The method is simple in operation and the yield is more than 85%.

Description

technical field [0001] The invention relates to the field of material science, in particular to an organophosphate ammonium salt-based transparent nucleating agent for polypropylene and a preparation method thereof. Background technique [0002] At present, polypropylene (PP) is a kind of translucent semi-crystalline resin with excellent performance, low price, wide application, and translucency. By adding nucleating agent, its crystallinity and transparency can be improved, and transparent polypropylene plastic with better performance can be obtained. . The polypropylene nucleating agents currently on the market mainly include sorbitol type and organic phosphate. In recent years, organophosphate nucleating agents have been widely used. Such nucleating agents can not only improve the transparency of polypropylene, but also improve the rigidity and heat distortion temperature of polypropylene. The existing organophosphate series nucleating agents are mainly metal salts, rep...
