High impact-proof nylon alloy and production thereof

Abstract

A high impact-resistant intensity nylon alloy and its production are disclosed. The nylon alloy consists of nylon alloy resin 60-85 proportions, thermoplastic polyurethane elastomer 15-40 proportions, and high-polymer plastifier. The production is carried out by mixing by proportioning, adding into double-screw extruder, and controlling temperature between 150-250deg.C, rotating speed between 10-100rpm. It achieves good impact and machining performance.

Description

technical field

[0001] The invention relates to a nylon alloy and a preparation method thereof. Background technique

[0002] The prior art closest to the present invention is Chinese patent CN 1422900A, published on June 11, 2003, and the title of the patent application for this invention is "Nylon Alloy Resin". Disclosed is a nylon alloy resin, its components and content (weight %): 20-80% of short-chain nylon, 10-70% of long-chain nylon, 0.1-15% of compatibilizer, and 0.1-0.5% of antioxidant. The alloy resin can improve the compatibility of long-chain nylon and short-chain nylon, improve the flexibility of short-chain nylon, and has a certain economic significance because the price is lower than that of long-chain nylon. The normal temperature notched impact strength of the nylon alloy resin reaches 83.74KJ / m 2 , 8 times that of pure nylon 1010 resin. The invention patent also discloses the production method of its products. After the resin and various additives are mi...

Examples

Embodiment 1

[0033] 800 grams of nylon resin and 200 grams of polyester thermoplastic polyurethane elastomer (brand JZ85) are pre-mixed and added to the twin-screw extruder, and the nylon alloy is extruded through the die under the above-mentioned process conditions, and water-cooled After the pellets were dried, they were injected into standard splines to measure their mechanical properties. Its performance is detailed in Table 1.

Embodiment 2

[0035] 796 grams of nylon resin, 199 grams of polyester thermoplastic polyurethane elastomer (brand JZ85), and 5 grams of macromolecular plasticizer consumption are pre-mixed and added in the twin-screw extruder. The alloy is extruded through a die, water-cooled, pelletized and dried, then injected into a standard spline to measure its mechanical properties. Its performance is detailed in Table 1.

Embodiment 3

[0037] 788 grams of nylon resin, 197 grams of polyester thermoplastic polyurethane elastomer (brand JZ85), and 15 grams of macromolecular plasticizer consumption are pre-mixed and added in the twin-screw extruder. The alloy is extruded through a die, water-cooled, pelletized and dried, then injected into a standard spline to measure its mechanical properties. Its performance is detailed in Table 1.
