Description

technical field

[0001] The invention relates to a preparation method of a plastic composition based on polyurethane and epoxy resin, in particular to a preparation method of a waterproof potting material based on polyurethane and epoxy resin composite material. Background technique

[0002] In order to survive and develop, human beings vigorously develop water resources. The concept of water resources development is the whole act of exploring, exploiting and utilizing underwater mineral resources, biological resources, water resources and space resources by using technical means. According to the different attributes of the developed resources, it can be divided into five aspects: biological resource development, mineral resource development, chemical resource development, energy development, and space utilization. Human beings have been developing water resources for thousands of years. Taking ocean development as an example, from the 1620s to the 1950s, some coastal count...
