Abstract

The invention relates to a cold-resistance super tough nylon polyolefin alloy, which is prepared by the following raw materials in part by mass: 45 to 75 parts of polycaprolactam, 15 to 30 parts of polyolefin, 4.8 to 9.7 parts of compatilizer, 5 to 15 parts of flexibilizer, 0.1 to 0.3 part of antioxygen and 0.1 to 0.5 part of assistant. The invention also provides a method for preparing the cold-resistance super tough nylon polyolefin alloy. In the method, polycaprolactam, polyolefin and the like are used as basic materials, maleic anhydride-grafted polyolefin is used as the compatilizer, maleic anhydride-grafted POE is used as the flexibilizer, and the double screw extrusion blending is used to prepare the cold-resistance super tough nylon polyolefin alloy. The cold-resistance super tough nylon polyolefin alloy prepared by the method is low in cost, high in comprehensive performance and high in low temperature and impact resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a cold-resistant super-tough nylon polyolefin alloy and a preparation method thereof. Background technique [0002] Polyamide (PA), commonly known as nylon (Nylon), is a general term for thermoplastic resins containing repeated amide groups - [NHCO] - in the main molecular chain. Nylon plastic has superior heat resistance, mechanical strength, and chemical resistance, and is widely used in electronic appliances, building materials, automobiles, films, monofilaments, etc. However, nylon plastics have defects such as a decrease in mechanical strength and a change in product size. For this reason, the pure resin raw materials on the market cannot meet the existing market demand, and the modification of nylon plastics has attracted people's attention. [0003] Cold-resistant super-tough nylon is a kind of modified nylon, which has the properties of low temperature resista...
