Embodiment 1

[0049]Preparation 1 of embodiment 1-modified resin

[0050] Mix 1.0 part of MAH, 0.1 part of antioxidant (compounded by antioxidants AO1010 and AO168 at a mass ratio of 1:1) and 100 parts of POE particles or powder through a temperature-controlled high-mixer for 2 minutes at a temperature of 25 °C, with a rotation speed of 500 rpm; then reduce the rotation speed to 50 rpm, and add 0.1 part of dicumyl peroxide crosslinking agent and 1 part of silane coupling agent A171 evenly by spraying. After the addition is complete, mix at a high speed of 700r / min at a temperature of 25°C for 10 minutes to obtain a premix; finally, the premix is ​​granulated through a twin-screw extruder with a length-to-diameter ratio of L / D of 44:1 to obtain modification Resin pellets.

[0051] The temperature of each zone of the extruder is: 80°C in the feeding zone, 140°C in the pre-melting zone, 200°C in the melting zone, 190°C in the metering zone, 200°C in the head, and 300 rpm.

Embodiment 2

[0052] Preparation 2 of embodiment 2-modified resin

After the addition is complete, mix at a high speed of 700r / min at a temperature of 25°C for 10 minutes to obtain a premix; finally, the premix is ​​granulated through a twin-screw extruder with a length-to-diameter ratio of L / D of 44:1 to obtain modification Resin pellets.

[0054] The temperature of each zone of the extruder is: 80°C in the feeding zone, 140°C in the pre-melting zone, 200°C in the melting zone, 190°C in the metering zone, 200°C in the head, and 300 rpm.

Embodiment 3

[0055] Preparation 3 of embodiment 3-modified resin

[0056] Mix 3.0 parts of MAH, 0.1 part of antioxidant (compounded by antioxidants AO1010 and AO168 at a mass ratio of 1:1) and 100 parts of POE particles or powder through a temperature-controlled high-mixer for 2 minutes at a temperature of 25 °C, with a rotation speed of 500 rpm; then reduce the rotation speed to 50 rpm, and add 0.1 parts of dicumyl peroxide crosslinking agent and 3 parts of silane coupling agent A171 evenly by spraying. After the addition is complete, mix at a high speed of 700r / min at a temperature of 25°C for 5 minutes to obtain a premix; finally, the premix is ​​granulated through a twin-screw extruder with a length-to-diameter ratio of L / D of 44:1 to obtain modification Resin pellets.

[0057] The temperature of each zone of the extruder is: 80°C in the feeding zone, 140°C in the pre-melting zone, 200°C in the melting zone, 190°C in the metering zone, 200°C in the head, and 300 rpm.

Abstract

The invention relates to a composite resin material with improved performance and application of the composite resin material in automobile decoration materials (such as layered automobile decoration materials). The composite resin material comprises a filler, a filler compatilizer, matrix resin, an optional antioxidant and the like, wherein the filler compatilizer is polyolefin-based modified resin double-grafted by MAH and a silane coupling agent.

Description

technical field [0001] The invention belongs to the field of resin graft modification and compounding, and in particular relates to a composite resin material with improved performance and its application in automobile decoration materials (such as layered automobile decoration materials). Background technique [0002] Polymer materials such as resins have low density and light weight, and have a wide range of application fields and performance advantages. As the application of polymer materials becomes more and more widespread, its common use with inorganic materials (such as fillers) is also more and more extensive. The blending of polymer materials and fillers (such as blending inorganic fillers) can effectively improve the mechanical properties, thermal properties, electrochemical properties or processing properties of plastics and other products in some cases, while reducing material costs to a certain extent. [0003] Fillers are usually inorganic mineral powders, fib...
