The invention discloses an elastic mobile phone support frame material, wherein a support post part is prepared from 100 mass parts of ethylene propylene diene monomer rubber and 43.5 parts of auxiliary agents, wherein the auxiliary agents are prepared from carbon black, vulcanization accelerators, zinc oxide, vulcanizing agents and anti-aging agents D according to the mass ratio of 20:4:5:10:4.5.The base part is made of HDPE (high density polyethylene). The two materials are well connected in a die cavity of an injection machine, so that the mobile phone support frame has high intensity. Themethod has the advantages that the process is simple, and the production efficiency is high. The prepared mobile phone support frame has the characteristics that the performance is good; the anti-aging performance is realized; the elasticity is high, and the like.
Description
technical field [0001] The invention relates to an elastic mobile phone support material. Background technique [0002] The mobile phone stand, also known as the lazy person stand, is a portable daily necessities. Because it is easy to use, it can prevent people from holding their mobile phones when watching videos, which causes arm fatigue, and is widely used by people. At present, the skin of most mobile phone holders in the domestic market is made of metal. This kind of mobile phone holder is not easy to bend when in use, and it is not easy to adjust the position of the mobile phone. state. The inside of this mobile phone holder is hollow, and it is prone to cracks at the bends after being used for a period of time. If the quality is not good, metal shavings may even fall off. There are also a small number of mobile phone holders coated with a layer of colored paint on the outside of the metal, and the paint on this painted mobile phone holder will also be found to come...
