Example Embodiment

[0016] Example 1

[0017] The formula is as follows: 100 parts of long-chain nylon PA1010, 10 parts of polyamide elastomer Pebax3533, 10 parts of plasticizer N-butylbenzenesulfonamide, 0.2 parts of antioxidant 168, 0.3 part of antioxidant 1098 and lubricant stearic acid Calcium 0.5 servings.

[0018] Add long-chain nylon, polyamide elastomer, antioxidant and lubricant calcium stearate to the high mixer according to the proportion required by the formula, and stir for 3 to 5 minutes under the condition of 400r / min. After the materials are completely mixed evenly, The plasticizer is added to the twin-screw extruder at a constant speed through the feeder, while the plasticizer is added at a constant speed through the liquid feeding port reserved in the extruder with a liquid metering pump to ensure that the ratio meets the formula requirements. All materials are extruded, cooled, granulated, dried, packaged, and finally finished after being melted and mixed evenly by twin-screw....

Abstract

The invention relates to a formula of a nylon hose. The nylon hose prepared according to the formula provided by the invention is mainly applied to oil hoses and brake hoses of cars. The formula proportion of the nylon hose in parts by weight is as follows: 100 of long-chain nylon, 1-30 of polyamide elastomer, 0-30 of a plasticizer, 0.1-3.0 of an antioxidant, and 0.1-3.0 of a lubricant. The nylon hose prepared by the formula provided by the invention has the characteristics of high strength, good low-temperature flexibility, oil resistance, good dimensional stability, stable extrusion molding and the like; and after the nylon hose is processed into tubing, the tubing completely accords with the requirements of the standard of DIN73378:1996-02, and completely meets the requirements of replacing the imported tubing PA11 and PA12.

Description

technical field [0001] The invention relates to a formulation of a nylon hose. The nylon hose prepared according to the formulation of the invention is mainly used for oil delivery pipes and brake hoses on automobiles. Background technique [0002] Automobile hoses, especially fuel pipes and brake hoses, have very high requirements on materials because they involve the safety of automobile driving. DIN73378: 1996-02 is an application standard for the "polyamide pipe" industry formulated according to the German FAKRA (Fachausschuβ Kraftfahrzeuge) committee SPA22 / 2 / 1R group No. 03 / 96 in 1996. At present, most of the domestic automobile industry still use this standard, or the enterprise standard revised according to this standard. There are strict regulations on the strength, corrosion resistance, thermal stability at high temperature and low temperature performance of materials in the standard. At present, this field is almost completely occupied by nylon 11 (PA11) and nylo...
