Embodiment 1

[0014] Embodiment 1 prepares nylon 66 modified plastics

[0015] The preparation method of the nylon 66 modified plastic in this embodiment includes the following steps: Step 1: vacuum-dry the nylon 66 resin and the nylon 6 resin respectively at a drying temperature of 85° C. and a drying time of 16 hours for later use.

[0016] Step 2: get the above-mentioned dried nylon 66 resin 52% and nylon 6 resin 18% in the component formula by weight percentage, get toughening agent 1.8%, coupling agent 1.2%, red phosphorus 17%, antioxidant 1.2% and Diatomaceous earth 8.8% is mixed by a mixer, and the sum of the quantities of each component is equal to 100%.

[0017] Step 3: Put the mixed mixture into a twin-screw mixer to melt at a temperature of 270°C, extrude through a twin-screw mixer, water-cool, cut into pellets, and dry to obtain the finished product.

Embodiment 2

[0018] Embodiment 2 prepares nylon 66 modified plastics

[0019] The preparation method of the nylon 66 modified plastic in this embodiment includes the following steps: Step 1: vacuum-dry the nylon 66 resin and the nylon 6 resin respectively at a drying temperature of 90° C. for 12 hours, and set aside for later use.

[0020] Step 2: Get the above-mentioned dried nylon 66 resin 77% and nylon 6 resin 9% according to the component formula by weight percentage, get toughening agent 1.2%, coupling agent 0.5%, magnesium hydroxide 5%, antioxidant 0.5% and 6.8% of white carbon black are mixed by a mixer, and the sum of the quantities of each component is equal to 100%.

[0021] Step 3: Put the mixed mixture into a twin-screw blender to melt at a temperature of 300°C, extrude through a twin-screw blender, water-cool, pelletize, and dry to obtain the finished product.

Embodiment 3

[0022] Embodiment 3 prepares nylon 66 modified plastics

[0023] The preparation method of the nylon 66 modified plastic in this embodiment includes the following steps: Step 1: vacuum-dry the nylon 66 resin and the nylon 6 resin respectively at a drying temperature of 87° C. and a drying time of 14 hours for later use.

[0024] Step 2: The component formula by weight percentage is to get the above-mentioned dried nylon 66 resin 64% and nylon 6 resin 13%, get toughening agent 1.5%, coupling agent 0.8%, aluminum hydroxide 11%, antioxidant 1.2% of the agent and 8.5% of diatomaceous earth are mixed by a mixer, and the sum of the quantities of each component is equal to 100%.

[0025] Step 3: Put the mixed mixture into a twin-screw mixer to melt at a temperature of 290°C, extrude through a twin-screw mixer, water-cool, pelletize, and dry to obtain the finished product.

Abstract

The invention discloses a nylon 66 modified plastic. The nylon 66 modified plastic comprises the following components in percentage by weight: 52-77% of nylon 66 resin, 9-18% of nylon 6 resin, 1.2-1.8% of a toughening agent, 0.5-1.2% of a coupling agent, 5-17% of a fire retardant, 0.5-1.2% of an antioxygen and 5-10% of a filling agent, wherein the sum is 100%. The nylon 66 modified plastic disclosed by the invention has the following technological effects; the nylon 66 modified plastic is reasonable in design; and the produced modified nylon 66 has low water absorptivity, good flame retardant property, friction resistance and anti-fatigue property and proper rigidity.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a formula of nylon 66 modified plastics and a preparation method thereof. Background technique [0002] Modified plastics are intermediate products in the petrochemical industry chain. With the continuous improvement of people's requirements for material performance, my country is becoming the world's largest potential market for modified plastics and the main driving force for demand growth. [0003] Modified nylon 66 is widely used in automobiles, machinery industry, electronic appliances, precision instruments and other fields due to its advantages of small specific gravity, high gloss, good toughness and good heat resistance. However, as people's living standards and industry standards are increasing day by day, the existing formulations and preparation methods of nylon 66 modified plastics can no longer meet the needs of production and life.
