Embodiment 1

[0026] The preparation method of the anti-deformation polycarbonate composite material for household appliances comprises the following steps: weighing 90 parts of PC-1250Y, 1 part of maleic anhydride grafted ABS (KT-2), 2 parts of MBS (EM500), Mix 1 part of bisphenol A epoxy resin in a high-speed mixer for 3-5 minutes; then add 0.1 part of antioxidant 1010, 0.2 part of antioxidant 168, 6 parts of polyphosphate PX-220, and 0.5 part of dipentaerythritol Stearate (PETS) was stirred at a low speed for 2 minutes to prepare the mixed material; the mixed material was added to a twin-screw extruder at a temperature of 240 degrees, a screw speed of 380 RPM, and a vacuum of 0.05 MPa to extrude and granulate to obtain a protective film for household appliances. Deformable polycarbonate composite.

Embodiment 2

[0028] The preparation method of the anti-deformation polycarbonate composite material for household appliances comprises the following steps: weighing 83 parts of PC-1250Y, 2 parts of maleic anhydride grafted ABS (KT-2), 4 parts of MBS (EM500), Mix 2 parts of bisphenol A epoxy resin in a high-speed mixer for 3-5 minutes; then add 0.2 parts of antioxidant 1010, 0.3 parts of antioxidant 168, 8 parts of polyphosphate PX-220, and 1 part of dipentaerythritol Stearate (PETS) was stirred at a low speed for 2 minutes to prepare the mixed material; the mixed material was added to a twin-screw extruder at a temperature of 270 degrees, a screw speed of 420 RPM, and a vacuum of 0.03 MPa to extrude and granulate to obtain a protective film for household appliances. Deformable polycarbonate composite.

Embodiment 3

[0030] The preparation method of the anti-deformation polycarbonate composite material for household appliances comprises the following steps: weighing 85 parts of PC-1250Y, 2 parts of maleic anhydride grafted ABS (KT-2), 3 parts of MBS (EM500), Mix 2 parts of bisphenol A epoxy resin in a high-speed mixer for 3-5 minutes; then add 0.2 parts of antioxidant 1010, 0.3 parts of antioxidant 168, 7 parts of polyphosphate PX-220, and 0.6 parts of dipentaerythritol Stearate (PETS) was stirred at a low speed for 2 minutes to prepare the mixed material; the mixed material was added to a twin-screw extruder at a temperature of 250 degrees, a screw speed of 400 RPM, and a vacuum of 0.04 MPa to extrude and granulate to obtain a protective film for household appliances. Deformable polycarbonate composite.

Abstract

The invention discloses a deformation-resistant polycarbonate composite material for household electrical appliances and a preparation method thereof, wherein the composite material comprises the following components in parts by weight: 83-90 parts of PC resin, 1-2 parts of a compatibilizer, 2-4 parts of a toughening agent, 1-2 parts of an end-capping agent, 6-8 parts of a flow modifier, 0.3-0.5 part of an antioxidant and 0.5-1 part of a lubricant. The prepared composite material greatly improves toughness, fluidity, forming stability and dimensional stability, reduces the internal stress of the material, is not deformed and cracked in high and low temperature cycling experiments, is mainly used in air conditioning panels, dehumidifier panels, small household appliance outer parts and thelike, can be subjected to two-color injection molding, has post-shrinkage temperature, and has the advantages of high and low temperature resistance, no deformation and the like.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a deformation-resistant polycarbonate composite material for household appliances and a preparation method thereof. Background technique [0002] With the progress of society and the continuous improvement of people's living standards, household appliances closely related to people's clothing, food, housing and transportation are also developing rapidly and undergoing innovation. The mainstream trend of traditional home appliances is developing toward health, aesthetics, intelligence, and environmental protection. Among them, aesthetics has become a kind of home appliance art that affects human life. The aesthetics of home appliances are not only ever-changing in color, but also innovative in structure. Among them, the curved surface structure not only makes the home appliance beautiful but also saves space, such as cylindrical air conditioners; curved TVs; wave-shaped dehumidif...
