Problems solved by technology

However, its common defect is that nylon 66 materials generally also contain maleic anhydride graft copolymer as a compatibilizer, and the compatibility between organosilicon compounds and maleic anhydride graft copolymer is poor, and it is used for a long time, especially in When used at high temperature for a long time, it is easy to produce phase separation, cracks or material precipitation on the surface of nylon 66 materials, which greatly affects the application effect of organosilicon compounds in nylon 66 materials.

Abstract

The invention relates to a nylon 66 material of a hydrophilic group modified organic silicon polymer. The nylon 66 material comprises the following components in parts by weight: 40-100 parts of nylon66 resin, 10-50 parts of a hydrophilic group modified organic silicon polymer and 1-10 parts of a maleic anhydride graft copolymer. The highest glow-wire ignition temperature (GWIT) of the nylon 66 material of the hydrophilic group modified organic silicon polymer can reach 858 DEG C, and can be applied to long-term unattended electric equipment as an engineering plastic part, so that probabilityof fire hazard caused by electric equipment in industrial production is greatly reduced. In addition, the nylon 66 material of the hydrophilic group modified organic silicon polymer also has excellent physical stability, and after the nylon 66 material of the hydrophilic group modified organic silicon polymer is placed for a long time under a high-temperature condition, the conditions of phase separation, cracks, material precipitation and the like do not occur.

Description

technical field [0001] The invention belongs to the field of flame retardant materials, in particular to a nylon 66 modified with a hydrophilic group-modified organosilicon polymer [0002] Material. Background technique [0003] Engineering plastics are currently the pillar industry of my country's manufacturing and chemical industries, and are widely and deeply used in various fields. Statistics show that more than 40% of the weight of modern electronic and electrical equipment is composed of engineering plastics. However, electronic and electrical equipment will cause overheating, leakage, short circuit, aging and other phenomena due to long-term work or improper operation, which in turn brings potential safety hazards and risks. Relevant international standards clearly stipulate that the glow wire ignition temperature (GWIT) of engineering plastic parts used in long-term unattended electrical and electronic fields must be greater than 750°C, and the GWIT of plastic par...
