An energy-saving and environment-friendly water storage tank with a protective shell and its manufacturing method

Abstract

The invention discloses an energy-saving and environment-friendly water storage barrel with a protective case and a manufacturing method thereof. The water storage barrel includes a hard plastic liner and a steel structure protective case, the hard plastic liner is blow-molded from recycled polyethylene material, and the recycled polyethylene The ethylene material includes the following raw materials by weight: 80-100 parts of recycled HDPE particles, 30-50 parts of modified LLDPE masterbatch, 1-2 parts of antioxidant, 0.5-1 part of light stabilizer, 2-5 parts of lubricant; HDPE granules are made from waste high-density polyethylene HDPE by cross-linking modified dicumyl benzene; modified LLDPE masterbatch is made from linear low-density polyethylene LLDPE modified by organically modified zirconium hydrogen phosphate OZrP, organically modified Zirconium hydrogen phosphate OZrP is prepared by intercalating zirconium hydrogen phosphate ZrP with triethylenetriamine. In the present invention, the regenerated polyethylene material is obtained by compounding the waste high-density polyethylene material through cross-linking modification and modified linear low-density polyethylene LLDPE, which improves the mechanical properties and rheological properties of the regenerated polyethylene material, and is manufactured by modifying the material. The energy-saving and environment-friendly water storage barrel improves the application of waste polyethylene plastics.

Description

technical field [0001] The invention relates to the field of water storage barrels, in particular to an energy-saving and environment-friendly water storage barrel with a protective shell and a manufacturing method thereof. Background technique [0002] In the plastics industry, polyethylene has the largest output, the widest application and the largest consumption, and the amount of waste plastics is quite amazing. According to incomplete statistics, the amount of waste polyethylene accounts for 48% of the total amount of waste plastics. Due to reasons such as molecular structure, polyethylene waste is difficult to degrade in the natural environment, causing pollution to the environment. With the continuous expansion of the polyethylene consumer market and the continuous increase and diversification of polyethylene consumer products, the amount of waste is also increasing. The recycling of waste polyethylene is the focus of waste plastic recycling. [0003] A water storage...

Problems solved by technology

However, after the waste plastics are used, a certain degree of aging occurs, that is, degradation or cross-linking. At the same time, due to the migration of processing aids, the mechanical properties and other properties of waste plastics will be relatively low, so the performance and grade of directly recycled products Lower, narrow application area
