Embodiment Construction

[0016] A glass fiber toughened composite nylon material, which is made by granulating the raw materials of the following parts by weight (kg):

[0017] Modified nylon PA66 60, nylon PA6 50;

[0018] The modified nylon PA66 is made by granulating the following raw materials in parts by weight: antioxidant 1010 0.8, antioxidant 168 0.2, polycaprolactone 3, silicone oil 0.4, silane coupling agent KH550 2, stearic acid Zinc 1, calcium stearate 0.3, oxidized polyethylene wax 1.8, glass fiber 10, nylon PA66 70, ASA resin 8, modified expanded vermiculite powder 8;

[0019] The preparation method of described modified expanded vermiculite powder is:

[0020] Burn the expanded vermiculite at 500°C for 4 hours, then grind it into powder, then soak it in 15% acetic acid solution for 4 hours, then wash it with deionized water until it is neutral, after drying, add an amount equivalent to the weight of the powder 4% silane coupling agent KH560 is stirred evenly, dried, and crushed into p...

Abstract

The invention discloses a glass fiber reinforced nylon composite material comprising modified nylon PA66 59-61 and PA6 49-51. The invention solves the performance defects such as general low strength of the existing nylon material; the glass fiber has good enhancement effect on nylon material; and compound of the glass fiber with other raw materials enables the obtained product to have stable quality, and realizes improved production efficiency and reduced production cost. Addition of the modified expanded vermiculite powder can improve the dimensional stability of the composite material provided by the invention.

Description

technical field [0001] The invention relates to the field of nylon materials, in particular to a glass fiber toughened composite nylon material. Background technique [0002] Because nylon has many characteristics, it is widely used in automobiles, electrical equipment, mechanical parts, transportation equipment, textiles, and papermaking machinery. [0003] With the miniaturization of automobiles, the high performance of electronic and electrical equipment, and the acceleration of the lightweight of mechanical equipment, the demand for nylon will be higher and greater. In particular, as a structural material, nylon has high requirements for its strength, heat resistance, and cold resistance. The inherent shortcomings of nylon are also important factors that limit its application, especially for PA6 and PA66, which have a strong price advantage compared with PA46 and PAl2, although some properties cannot meet the development requirements of related industries. Therefore, ...
