Modified flame-retardant PET (polyethylene terephthalate) material

Abstract

The invention provides a modified flame-retardant PET (polyethylene terephthalate) material. The PET material comprises the following raw materials in percentage by weight: 70-80% of polyethylene terephthalate, 2-6% of modified montmorillonite, 2-4% of nano titanium nitride and 10-20% of a composite flame retardant. The invention discloses the modified flame-retardant PET material which is reasonable in component preparation, a preparation process is scientific, simple and convenient, and modified preparation is achieved by mixing inorganic nano particles with a flame retardant to ensure that the prepared PET material not only has excellent molding crystallization properties and mechanical properties, but also has excellent flame-retardant property, and is suitable for preparation of PET sheets in various fields.

Description

technical field

[0001] The invention relates to a PET material, in particular to a modified flame-retardant PET material, which belongs to the technical field of plastic materials. Background technique

[0002] Polyethylene terephthalate PET is an important engineering plastic, which has excellent physical and mechanical properties in a wide temperature range, and can still maintain excellent electrical insulation properties under high temperature and high frequency. It is used to produce PET sheets are widely used in electronics, food, medicine, office supplies, toys and other industries. However, PET also has many shortcomings, such as: poor impact performance, low tensile and bending strength, slow crystallization, long molding cycle, poor flame retardancy, etc., which limit its application in many aspects, so it is necessary to carry out research on PET materials. Certain modifications are required to obtain PET materials that meet the requirements of various applicatio...
