Problems solved by technology

However, nylon material has poor toughness, especially when used at low temperature, it is easy to become brittle. For materials with long-term use conditions below zero degrees Celsius, the low-temperature strength must be high. Specially modified nylon can be used at -30°C. Long-term use, and its impact performance is only slightly reduced, which can meet the long-term use requirements

Abstract

The invention discloses a low temperature resistant and high strength nylon, which comprises the following components by weight: 40-60 parts of PA6; 10-20 parts of PA66; and 10-30 parts of a toughening agent. Specifically, when the total mass of PA6, PA66 and the toughening agent is 100 mass parts, 0.1-0.8 part of an assistant and 0-2 parts of toner are additionally added, PBT, glass fiber, inorganic filler, a flame retardant and a synergistic flame retardant are 100 mass parts totally, and the assistant and toner are added in an additional way. The low temperature resistant toughening agent adopted by the invention is grafted EPDM, and the impact strength retention rate is 85% or above under a condition of minus 30DEG C.

Description

technical field [0001] The invention relates to a low-temperature-resistant high-strength nylon and a preparation method thereof. Background technique [0002] Nylon is one of the earliest developed engineering plastics. It has the advantages of high mechanical strength, good toughness, fatigue resistance, self-lubrication, small friction coefficient, wear resistance, heat resistance (long-term use within 100°C), easy modification and molding, etc. , has good comprehensive performance and wide application. However, nylon material has poor toughness, especially when used at low temperature, it is easy to become brittle. For materials with long-term use conditions below zero degrees Celsius, the low-temperature strength must be high. Specially modified nylon can be used at -30°C. Long-term use, and its impact performance is only slightly reduced, which can meet the long-term use requirements. Contents of the invention [0003] The technical problem to be solved by the pres...
