Abstract

An anti-collision composite material, which comprises 100 parts by weight of modified epoxy resin, 5-40 parts by weight of active toughening agent, 0.03-0.05 parts by weight of surfactant, 20-50 parts by weight of powder, and 10-50 parts by weight of gravel material. parts by weight. The invention overcomes the deficiencies of the existing concrete gate wall which is not resistant to collision, friction and the like, and has the characteristics of high epoxy resin hardness, strong cohesion, polyurethane toughness and wear resistance. The invention also discloses the preparation method of the anti-collision composite material.

Description

technical field [0001] The present invention relates to a composite material with a new structure, more specifically, it is an anti-collision composite material, and also relates to a preparation method of the anti-collision composite material. technical background [0002] Ship lock is one of the important projects in water conservancy and hydropower projects, and it is a key navigable structure. It can not only greatly improve shipping conditions and undertake frequent navigation tasks, but also play an indispensable role in the normal and effective operation of flood control and power generation functions of water conservancy and hydropower projects. The role of neglect. The durability of ship locks has always been an important research topic in the field of water conservancy and hydropower. However, the concrete of ship lock walls is easily damaged by the collision and friction of passing ships, forming scratches, which greatly affects the durability of ship locks and af...
