Abstract

The invention discloses a preparation method of a fusible multilayer composite asphalt filling bag. The method is characterized in that the method comprises the following steps: utilizing polyolefin, a modified polyolefin material and a compounding agent to prepare a fusible multilayer composite asphalt filling bag film blowing material, carrying out blow molding of the film blowing material and processing master batches through adopting a film blowing set to form a fusible multilayer composite asphalt filling bag body having a thickness of 20-100mum, and carrying out slitting and heat sealing to prepare the fusible multilayer composite asphalt filling bag. The processing master batches are a fusion compound comprising a polyethylene resin and a processing assistant. The fusible multilayer composite asphalt filling bag has the characteristics of high temperature filling resistance, realization of complete mixed fusion with asphalt, no edge leakage, no seepage, high heat sealing strength, wide range of the use temperature, ultraviolet resistance, weather resistance, strong designability, and relative low price. The fusible multilayer composite asphalt filling bag is used for the high and low temperature filling of pavement asphalt and various modified asphalts, and can be widely used in the petroleum field and the building field.

Description

technical field [0001] The invention relates to the technical field of preparation of functional polymer materials, in particular to a method for preparing a meltable multi-layer composite asphalt filling bag. Background technique [0002] Asphalt is one of the most basic materials in the road and construction industry. With the rapid development of the national economy and the increase in the country's investment in infrastructure construction, its current domestic consumption has exceeded 15 million tons per year, and has been growing steadily momentum is growing. [0003] Asphalt needs to be transported, packaged and transported before final use, and its transport mainly includes the following two methods: long-distance fluid transport by pipeline and sub-packaging and distribution. [0004] The former is mainly suitable for short-distance transportation or filling of asphalt transfer and modification stations, because this transportation mode often requires a higher tem...
