Problems solved by technology

Nylon 11 and Nylon 12 have not yet been industrialized in China, and the supply is limited and the price is high. However, long-carbon-chain diamine, one of the main raw materials for domestic long-carbon-chain nylon, is mainly derived from castor oil. The output is limited and the price is relatively expensive.

Embodiment 1

[0017] The formula is as follows: 100 parts of copolymerized nylon PA610 / 613 (where PA613 accounts for 10% of the copolymerized nylon), 10 parts of plasticizer N-butylbenzenesulfonamide, 10 parts of impact modifier EPDM-g-MA, antioxidant 1681.5 parts, antioxidant 1098 1.5 parts.

[0018] Add the copolymerized nylon PA610 / 613, antioxidant, and impact modifier EPDM-g-MA into the high mixer according to the ratio required by the formula, and stir for 8 minutes under the condition of 400r / min. After the materials are completely mixed, pass The feeder is fed into the twin-screw extruder at a constant speed, and the plasticizer is fed in at a calculated 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 melted and mixed uniformly by twin-screws, then extruded, cooled, granulated, dried and packaged to obtain the final product.

Abstract

The invention provides a formula of a nylon hose material, wherein the nylon hose material at least takes a polyamide resin, a plasticizer and an impact modifier as production raw materials, the polyamide resin is obtained by copolymerizing short-chain odd-even nylon and short-chain even-even nylon, the plasticizer is one or a combination comprising a plurality of materials selected from higher alcohol, hydroxybenzoate, aromatic sulfonamide and phenol, and the impact modifier is one or a combination comprising a plurality of materials selected from polyolefin, an olefin copolymer and an elastomer. According to the invention, the nylon hose material has the characteristics of low price, high strength, good low-temperature flexibility, oil resistance, good dimensional stability, stable extrusion molding and the like compared with the long carbon chain nylon hose, and completely meets the requirements of the nylon hose for vehicles.

Description

technical field [0001] The invention relates to a formula of nylon hose material, which belongs to the field of preparation and production of polymer materials. Background technique [0002] Nylon hoses are widely used in the automotive industry. Nylon hose is mainly made of long carbon chain nylon as the matrix resin, which is toughened and modified. In foreign countries, nylon 11 and nylon 12 are used as the main raw materials. In recent years, nylon hose materials with long carbon chain nylon 1012 and nylon 1010 as the main raw materials have been developed in China. Nylon 11 and nylon 12 have not yet been industrialized in China, their supply is limited, and their prices are high. However, long-carbon-chain diamines, one of the main raw materials for domestic long-carbon-chain nylon, are mainly derived from castor oil, with limited production and high prices. Contents of the invention [0003] The present invention discovers a formula of nylon hose material, which us...
