Abstract

The invention relates to a nylon material and a preparation method thereof, in particular to a micro foamed nylon material for automobile engine covers and a preparation method of the micro foamed nylon material. The material of the present invention comprises the following compositions in parts by weight: 60 to 80 parts of nylon, 5 to 25 parts of glass fiber, 0 to 15 parts of filler, 0.3 to 1 part of tackifier, 0.2 to 0.6 part of anti-hydrolysis agent, 0.5 to 5 parts of foaming agent, 2 to 10 parts of foaming auxiliary agent, 0.2 to 0.5 parts of lubricant, and 0.2 to 0.5 parts of stabilizer.The micro foamed nylon material of the invention has the characteristics of high cell density and good apparent quality. An automobile engine cover product prepared from the material has the characteristics of high rigidity, good dimensional stability, high yield, etc.; under the circumstance that the overall product weight loss is over 18%, the strength retention is more than 88%; moreover, the product also has good long-term thermal aging performance, which meets the requirements of long-term thermal oxygen ageing of a host plant at 150 DEG C for 1000 hours; and in addition, the product process is easy to industrialize.

Description

technical field

[0001] The invention relates to a micro-foamed nylon material and a preparation method thereof, in particular to a micro-foamed nylon material for an automobile engine cover and a preparation method thereof, and belongs to the field of material technology. Background technique

[0002] Under the dual pressure of energy crisis and environmental pollution, lightweight has become an inevitable trend in the development of today's automobile industry. According to related research, for every 10% reduction in vehicle weight, fuel consumption can be reduced by 8% to 10%. However, at present, compared with foreign developed countries, the weight of Chinese cars is 8-10% higher than that of foreign developed countries, and the weight of commercial vehicles is 10-15% higher. To catch up with the world's advanced level, the weight of vehicles needs to be reduced by 25-30%. Therefore, my country's automobile lightweight task is very urgent.
