Description
Technical field
The present invention relates to a kind of high cold-resistant, hydrolysis-resistant reinforced nylon 6 and preparation method thereof.
Background technology
Nylon 6 is a kind of broad-spectrum engineering plastics, is made by caprolactam polymerization, and its fusing point is 215～225 ℃, and is lower than nylon 66; In addition, because degree of crystallinity is lower than PA66, its Young's modulus is also low, and water absorbability is bigger, but good toughness is all good resin of rerum natura and price.
Amide group in the PA6 molecular chain has polarity, can form hydrogen bond, so the mechanical property excellence, and as tensile strength height, good toughness, ability repeated stock vibrations are tough and tensile engineering plastics; PA6 belongs to crystalline material, fusing point is obvious; Surface hardness is big, abrasion performance, frictional coefficient are little, self lubricity and noise reduction are arranged.The use temperature scope is at-40 ℃～100 ℃; Electrical insulation capability is good, anti-electric arc, but be subject to Temperature Influence; Be easy to painted and nontoxic; Organic solvents such as oil resistant, hydro carbons, ester class, anti-weak base, but not acidproof and oxygenant, not water-fast, alcohols isopolarity solvent; Be easy to machine-shaping.Weak point is that water-intake rate is higher, and dimensional stability is relatively poor.Generally can by strengthen, method of modifying such as toughness reinforcing, filling overcomes its weak point, and other performance is greatly improved.
Reinforced Nylon 6 kind in the market is a lot, and there is very big-difference in Reinforced Nylon 6 rerum naturas of different manufacturers production.In general, external manufacturer such as Bayer, BASF, Dupont etc. have a lot of different grades, and as high rigidity, high cold-resistant, heat-proof aging etc., still, the resistance to impact shock of general normal temperature can reach 25KJ/m
2Reinforced Nylon 6 be very high level just, therefore can't satisfy the needs of relevant field development, must the new Reinforced Nylon 6 of development research.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of high cold-resistant, hydrolysis-resistant reinforced nylon 6 and preparation method thereof, to overcome the above-mentioned defective that prior art exists, satisfy the needs of relevant field development.
