PURPOSE: A method for preparing biodegradable volatile polyethylene foam is provided to protect the iron or nonferrous metals from impact and to prevent corrosion and discoloration of products. CONSTITUTION: A method for preparing biodegradable volatile polyethylene foam includes: (S10) forming a first mixture by mixing and stirring sodium benzoate, benzotriazole, sodium molybdate and dextrin; (S20) pulverizing the first mixture; (S30) forming a second mixture by mixing and stirring hydroxy ethyl cellulose, zinc stearate and polyethylene wax; (S40) forming a third mixture by mixing and stirring polyethylene resin, alpha-olefin-based polymer and metal with thermal conductivity more than 200Kcal/mhr°C; and (S50) forming the polyethylene form by making the third mixture to foam. |
