Technical Field
The invention relates to a nylon hose formula, and belongs to the field of polymer processing.
Background
Nylon, which is a commonly used engineering material, has excellent corrosion resistance, tensile strength, abrasion resistance, and fluidity, and thus is easy to process and manufacture, and thus is widely used in various aspects of industry, such as automobiles, electronic and electronic appliances, machinery, and living goods.
In practical use engineering, especially in the process of conveying liquid or fluid materials, the shape of the hose may not be fixed, and in addition, in a conveying environment with large flow and high pressure, the hose is greatly impacted, so that a nylon material with excellent toughness and high impact strength is needed. Therefore, various improvements are made on nylon materials by domestic and foreign companies, and super-tough nylon alloys, high-impact nylon alloys and other materials are derived.
The invention discloses a super-tough nylon alloy and a preparation process thereof, which greatly improve the strength and impact resistance of the nylon alloy; the invention discloses a super-tough nylon 6 alloy prepared by an in-situ method and a method thereof, which greatly improve the toughness of the nylon alloy. Although the above patents all obtain comparatively excellent nylon materials, none of them provides a technical scheme which can improve the toughness of nylon materials and also can improve the high impact strength of nylon materials.

The invention aims to provide a nylon material with good toughness and high impact strength.
The invention discloses a nylon hose formula which comprises the following components:
further, the nylon is nylon 66.
Further, the main toughening agent is a copolymer of ethylene and higher alpha-olefin.
Further, the auxiliary toughening agent is hydrogenated styrene-butadiene-styrene block copolymer.
Further, the anti-aging agent is 2-mercaptobenzimidazole.
Further, the antioxidant is antioxidant 1010.
Further, the compatilizer is polypropylene grafted maleic anhydride.
Further, the nylon 6660 parts, the ethylene-higher alpha-olefin copolymer 15 parts, the hydrogenated styrene-butadiene-styrene block copolymer 0.1 part, the 2-mercaptobenzimidazole 0.2 part, the antioxidant 10100.2 part, and the polypropylene grafted maleic anhydride 6 parts.
The modified polypropylene composite material comprises 6667.5 parts of nylon, 16.5 parts of ethylene and higher alpha-olefin copolymer, 0.55 part of hydrogenated styrene-butadiene-styrene block copolymer, 0.7 part of 2-mercaptobenzimidazole, 10100.7 parts of antioxidant and 15.5 parts of polypropylene grafted maleic anhydride.
Further, the nylon 6675 parts, the ethylene/higher alpha-olefin copolymer 18 parts, the hydrogenated styrene-butadiene-styrene block copolymer 1 part, the 2-mercaptobenzimidazole 1.2 parts, the antioxidant 10101.2 parts, and the polypropylene grafted maleic anhydride 25 parts.
Compared with the prior art, the product of the invention has better toughness and impact strength, and can meet the use requirements under the environment of large flow and high pressure. In addition, the raw materials of the formula are derived from the existing mature technology, so the invention has the characteristics of low cost, easy processing and manufacturing and the like, thereby having better market prospect.
