AI Technical Summary

Problems solved by technology

PC has poor hydrolysis resistance and cannot be used for products that are repeatedly subjected to high-pressure steam
The main performance defect of PC is that the stability of hydrolysis resistance is not high enough, it is sensitive to notch, it has poor resistance to organic chemicals and scratches, and it will turn yellow when it is exposed to ultraviolet light for a long time.

Abstract

The invention discloses a palm wax modified polyester material which comprises the following raw materials in parts by weight: 140-200 parts of polycarbonate, 40-50 parts of phosphatized palm wax solution, 0.3-1 part of lauryl dimethyl amine oxide, 13-20 parts of sisal fibers, 4-7 parts of dioctyl sebacate, 3-5 parts of calcium oxide and 0.08-0.1 part of triethylamine. According to the palm wax modified polyester material, the dispersion compatibility of all the raw materials can be effectively improved, and the mechanical stability of a finished product material is improved; through doping ofthe fibers, the palm wax modified polyester material also has good toughness and strength and is excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a palm wax modified polyester material and a preparation method thereof. Background technique [0002] Polycarbonate is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonate has been produced industrially. Due to the special structure of polycarbonate, it has become the fastest growing general-purpose engineering plastic among the five major engineering plastics. PC is an almost colorless glassy amorphous polymer with good optical properties. PC high molecular weight resin has high toughness, the Izod notched impact strength is 600-900J / m, and the...
