Problems solved by technology

The inherent shortcomings of nylon are also important factors that limit its application, especially for the two major varieties of 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

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 toughened composite nylon material, modified nylon PA66 59-61 and nylon PA6 49-51. The invention solves performance defects such as low strength of the existing nylon materials. The glass fiber has a good reinforcing effect on the nylon materials and is compounded with other raw materials. The resulting product has stable quality, improves production efficiency and reduces production costs. The addition of modified expanded vermiculite powder can well enhance the dimensional stability of the present invention.

Description

Technical field [0001] The present invention involves the field of nylon materials, and it is precisely a compound nylon material with glass fiber. Background technique [0002] Because nylon has a lot of characteristics, it is widely used in automotive, electrical equipment, mechanical structures, transportation equipment, textiles, and papermaking machinery. [0003] With the miniaturization of cars, the high performance of electronic and electrical equipment, and the lightweight process of mechanical equipment, the demand for nylon will be higher and larger.Especially as structural materials, nylons have put forward high requirements for its strength, heat resistance, and cold resistance.The inherent disadvantage of nylon is also an important factor restricting its application. Especially for the two varieties of PA6 and PA66, it has a strong price advantage compared with PA46 and PAL2. Although certain performances cannot meet the requirements of the development of related in...
