Embodiment 1

[0022] Example 1 Preparation of a Metal Aging Resistant Reinforced Nylon Material of the Present Invention (1)

[0023] The raw materials were weighed according to the following weight ratio: 45% nylon, 25% continuous long glass fiber, 24% compound halogen-free flame retardant, 0.3% antioxidant, 0.3% anti-copper agent, 5% compatibilizer, Lubricant 0.4%.

[0024] Add nylon, compound type halogen-free flame retardant, antioxidant, anti-copper agent and compatibilizer into the three-screw extruder in proportion. The body is calendered and infiltrated into the mold, the mold temperature is 280°C, and the temperature of the three-screw extruder is 270°C; then the continuous long glass fiber is drawn into the mold at a speed of 150m / min, and the length of the mold is 4m. After full calendering and infiltration, cool , pelletized, you can get metal aging-resistant reinforced nylon material.

Embodiment 2

[0025] Example 2 Preparation of a Metal Aging Resistant Reinforced Nylon Material of the Present Invention (2)

[0026] The raw materials were weighed according to the following weight ratio: nylon 49%, continuous long glass fiber 23%, compound halogen-free flame retardant 22%, antioxidant 0.3%, anti-copper agent 0.3%, compatibilizer 5%, Lubricant 0.4%.

[0027] Add nylon, compound type halogen-free flame retardant, antioxidant, anti-copper agent and compatibilizer into the three-screw extruder in proportion. The body is calendered and infiltrated into the mold, the temperature of the mold is 270°C, and the temperature of the three-screw extruder is 270°C; then the continuous long glass fiber is drawn into the mold at a speed of 130m / min, and the length of the mold is 4m. After full calendering and infiltration, cool , pelletized, you can get metal aging-resistant reinforced nylon material.

Embodiment 3

[0028] Example 3 Preparation of a Metal Aging Resistant Reinforced Nylon Material of the Present Invention (3)

[0029] The raw materials were weighed according to the following weight ratio: 44% nylon, 27% continuous long glass fiber, 22% compound halogen-free flame retardant, 0.4% antioxidant, 0.3% anti-copper agent, 6% compatibilizer, Lubricant 0.3%.

[0030] Add nylon, compound type halogen-free flame retardant, antioxidant, anti-copper agent and compatibilizer into the three-screw extruder in proportion. The body is calendered and infiltrated into the mold, the temperature of the mold is 300°C, and the temperature of the three-screw extruder is 280°C; then the continuous long glass fiber is drawn into the mold at a speed of 150m / min, and the length of the mold is 5m. After full calendering and infiltration, cool , pelletized, you can get metal aging-resistant reinforced nylon material.

Abstract

The invention relates to a metal ageing resisting type enhanced nylon material. The nylon material is prepared from the following raw materials in percentage by weight: 44 to 63% of nylon, 23 to 32% of continuous long glass fibers, 22 to 26% of a complex halogen-free flame retardant, 0.3 to 0.5% of an antioxidant, 0.3 to 0.5% of an anti-copper agent, 4 to 6% of a compatilizer, and 0.1 to 0.6% of a lubricant. The invention further provides a preparation method of the metal ageing resisting type enhanced nylon material. The metal ageing resisting type enhanced nylon material has an advantage that the proper anti-copper agent is adopted, so that the copper damage resisting effect is obvious; the metal ageing resisting type enhanced nylon material further has the advantages of being high in compatibility for nylon, high in dispersing performance, free of migration, free of pollution, resistant to water, high in oil extraction performance, and free of influence on electric insulation performance and other performances of the nylon; meanwhile, a rolling and infiltration mode is adopted in production, so that the retention length of the continuous long glass fibers is more than that of the common method, and thus, the material is very high in strength.

Description

technical field [0001] The invention relates to the field of metal aging-resistant reinforced nylon material, in particular to a method for preparing the metal aging-resistant reinforced nylon material. Background technique [0002] Nylon, especially modified nylon, has been widely used in the field of home appliances due to its excellent performance and low price. Different uses have different requirements for the performance of nylon. When nylon is used in the field of sockets, in addition to flame retardancy, mechanical properties, In addition to dielectric properties and heat resistance, thermo-oxidative aging performance is also an important performance requirement. The thermo-oxidative degradation of nylon is carried out according to a typical free radical chain reaction mechanism. The hydroperoxide generated in the reaction is decomposed by heat to generate free radicals that cause a chain reaction. This reaction is generally carried out at a temperature of 120 ° C or...
