Problems solved by technology

However, the hydrophobic additives used are all low-molecular polar compounds and are not fixed. Soaking in water or its solution will quickly cause its hydrophobic components to be extracted and lose its due effect.
On the other hand, its original intention is to introduce alkyl branches int

Abstract

The invention relates to a hydrophobic polyolefin composition and a preparation method thereof. The composition comprises the following components: polyolefin resin, an elastomer, mineral powder, organic fluoride, an antioxidant, other processing aids and functional aids. The hydrophobic property of a material is improved through a special system and structure, and meanwhile, the mechanical property of the material is maintained, so that the use requirements in the fields of automobiles, electronic appliances, household appliances, buildings, offshore power generation and the like are met.

Description

technical field [0001] The invention belongs to the field of modified plastics and its preparation, in particular to a hydrophobic polyolefin composition and its preparation method. Background technique [0002] With the advancement of national energy conservation and emission reduction measures and the rapid development of the modern modified plastics industry, many aspects can be combined to achieve coordinated development. [0003] Offshore photovoltaic power generation is a major part of the country's energy conservation and emission reduction, but its base is blow molded with polypropylene or polyethylene, which requires a service life of 30 years, but after a period of time, cracks and water leakage are found. Water molecules penetrate in large quantities, resulting in a violation of the structural strength. [0004] In building construction, water insulation is required between layers. Asphalt is commonly used. In recent years, more and more PP materials have been gr...
