Preparation of low-carbon energy-saving modified polyethylene waterproof special material

Abstract

The invention relates to the preparation of a low-carbon energy-saving modified polyethylene waterproof special material, which belongs to the field of the preparation of high molecular materials. The preparation of the low-carbon energy-saving modified polyethylene waterproof special material solves the problems of low performance and high price of a single raw material of polyethylene; and recovered polyethylene plastics is applied as a modified base material, which conforms to the requirements of energy saving, low carbon and environmental protection and also widens the application field of the recovered material. The low-carbon energy-saving modified polyethylene waterproof special material belongs to a blended modified material and has low manufacturing cost and excellent performance, and various advantages of the low-carbon energy-saving modified polyethylene waterproof special material are incomparable to novel materials. The modified polyethylene waterproof special material has the excellent performances of high tensile strength, large elongation at break, corrosion resistance, ageing resistance, good impermeability and the like; the modified polyethylene waterproof special material is used for manufacturing products, such as impermeable waterproof coiled materials, plates, sheets and the like, and also has the advantage that cold construction can be carried out; and the modified polyethylene waterproof special material is largely used in the engineering of water prevention, corrosion prevention and leakage prevention in various fields of railways, bridges, refuse landfill and the like, and has extensive market.

Problems solved by technology

[0003] my country has entered the era of high-speed development and construction. In 2008, the country issued ten economic measures worth RMB 4 trillion to stimulate domestic demand. Among them, the construction of railway passenger lines, intercity railways, coal transportation channel projects and the development of western trunk railway projects will be the next two years. In the key areas of railway construction in my country, 1.3 trillion yuan will be invested in railway construction in the past two years; The demand for materials provides a broad market, especially high-performance PE waterproof materials are urgently needed in various construction fields such as chemical industry, railways, bridges, tunnels, building materials, and landfills in my country! Facing the urgent needs of the market, especially for the shortcomings of existing PE materials such as high cost, low performance, easy aging, and low elongation at break, it is the general trend to develop this energy-saving and low-carbon modified PE waterproof special material.
