Problems solved by technology

[0002] Mobile phones are common items in daily life, but the use of mobile phones has radiation effects on the human body. At present, most of the plastics used to make mobile phone cases are relatively ordinary, not only do not have radiation protection, but also have poor strength. To improve strength, add carbon fiber, but the cost is relatively high

Embodiment 1

[0014] Taking the preparation of 100kg of plastic for mobile phone casing as an example, the preparation steps of the present invention are as follows:

[0015] Step 1: Put 55kg PA6 in a thermostat at 230℃ and bake for 6-7 hours, add 25kg basalt fiber, stir and mix evenly, lower the temperature of the thermostat to 100℃, and leave it for 20 minutes;

[0016] Step 2: Put the mixture obtained in step 1 into an injection molding machine, add 10 kg of aluminum oxide, 5 kg of antimony trioxide, and 5 kg of vinyl triethoxy silane and mix them uniformly, and then perform injection molding to obtain a mobile phone shell.

Embodiment 2

[0018] Taking the preparation of 100kg of plastic for mobile phone casing as an example, the preparation steps of the present invention are as follows:

[0019] Step 1: Put 50kg of PA6 in a thermostat at 230℃ and bake for 6-7 hours, add 25kg of basalt fiber, stir and mix evenly, reduce the temperature of the thermostat to 100℃, and leave it for 20 minutes;

[0020] Step 2: Put the mixture obtained in step 1 into an injection molding machine, add 15 kg of magnesium oxide, 5 kg of antimony trioxide, and 5 kg of vinyl triethoxy silane and mix them uniformly, then perform injection molding to obtain a mobile phone shell.

Abstract

The invention discloses a plastic for a mobile telephone shell and a preparation method thereof. The plastic comprises by mass: 30 to 70% of a high-molecular matrix material, 10 to 20% of a heat-conducting filling material, 5 to 10% of a fire retardant, 1 to 5% of a coupling agent and 25 to 40% of a basalt fiber, wherein the high-molecular matrix material is PA6, the heat-conducting filling material is aluminum oxide or magnesium oxide, the fire retardant is antimony trioxide, the coupling agent is vinyltriethoxysilane, and the filament diameter of the basalt fiber is 9 to 18 mu m. The plastic has the advantages of radiation protection performance, high strength, low cost, etc.

Description

Technical field [0001] The invention discloses a plastic for a mobile phone casing and a preparation method thereof, which are applied to the field of manufacturing the mobile phone casing material. Background technique [0002] Mobile phones are common supplies in daily life, but the use of mobile phones has radiation effects on the human body. At present, most of the plastics used to make mobile phone cases are relatively ordinary, not only do not have radiation protection, but also have poor strength. To improve the strength, add carbon fiber, but the cost is relatively high. Summary of the invention [0003] In order to solve the defects of the existing technical solutions, the present invention discloses a plastic for mobile phone housing with radiation protection, high strength and low cost, and a preparation method thereof. [0004] The invention discloses a plastic for a mobile phone shell, which comprises 30%-70% polymer body material, 10%-20% thermal conductive fi...
