Problems solved by technology

[0005] For example, in the domestic market, there are anecdotes about the prices of related materials from large foreign companies, while the products of domestic manufacturers have sacrificed some of the advantages of nylon 6 itself, or the product quality stability is not well controlled due to insufficient craftsmanship or technology. Disadvantages that are not suitable for large-scale production

Embodiment 1

[0011] Embodiment 1 provides a special material for nylon casing, which is composed of the following components by weight ratio, nylon 6: 78%; cold-resistant agent: 12%; reinforcing agent: 4%; antioxidant: 1.0%; composite anti-aging agent: 2.5% %; other additives: 2.5%.

[0012] The specific method of the present invention is as follows: first dry nylon 6 at 85 degrees, then weigh it with all other additives according to the proportion and mix it in the mixer for 10 minutes at a low speed. The wall gap is less than 0.5 cm, and the mixing effect of raw and auxiliary materials should be visually observed that the various particles and powders are basically uniform, without obvious agglomeration or aggregation; the twin-screw extruder uses a 40 aspect ratio and medium-strength shear; adopts water-cooled strand cutting Through screening and dehydration, the special material for nylon casing can be obtained.

Abstract

The invention discloses a special material for a nylon sleeve. The special material comprises the following components in weight ratio: 49.5-90% of nylon 6, 1-35% of an anti-freezing agent, 1-10% of enhancer, 0.1-5.0% of antiager, 0.3-1.5% of antioxidant, and 0.3-5.5% of other assistants. The special material for the nylon sleeve, provided by the invention, can tolerate the low temperature of negative 40 DEG C and still keep good toughness, is easy to scale up to industrial production, is greatly increased in rigidity, weather resistance, age resistance and wear resistance, is convenient to produce, process, and procure, and adopts domestic materials and domestic manufacturing equipment, thereby being greatly improved in competitive power.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a special material for nylon casing. The invention also relates to a method for making the special material for the nylon sleeve. Background technique [0002] When manufacturing railway sleeper repair casing products, it is required that the material can withstand extremely low temperature and still maintain good toughness, and at the same time, the material can still maintain high strength under the high temperature of direct sunlight in summer, as well as long-term weather resistance and aging resistance characteristics etc. [0003] Nylon 6 is a polyamide resin, one of the most widely used engineering plastics. Its amide group is polar and has a strong hydrogen bond in its structure, which makes nylon 6 have a high melting point and good Excellent physical and mechanical properties, wear resistance and self-lubricating properties, these comprehensive ...
