Abstract

The invention relates to a bendable organic imitation steel fiber for building concrete. The preparation method of the bendable organic imitation steel fiber comprises the following steps of: adding a stiffness enhancing agent, a reinforcing agent, a lubricating agent, and the like to polypropylene used as a main raw material for blending; and then carrying out wire drawing with high multiplying power to manufacture a coarse fiber with teeth. The fiber can be used for suppressing a plastic shrinkage microcrack of cement mortar and concrete and improving the strength and the toughness of a cement product, and because the added stiffness enhancing agent forms a structure coupling hardness with softness together with the polypropylene, the fiber overcomes the defects of large elasticity and difficult bending of a pure polypropylene organic imitation steel fiber.

Description

Technical field: [0001] The invention relates to a polypropylene crude fiber and a preparation method thereof, in particular to a preparation method of a bendable organic imitation steel fiber for building concrete. Background technique: [0002] Concrete is a very important building material. It is currently developing towards high performance, high functionality, and high durability. However, the inherent shortcomings of concrete, such as low tensile and compressive strength, high brittleness, poor toughness, and poor resistance to deformation, restrict its development and development. Therefore, improving the flexural resistance and flexural toughness of concrete, and improving the durability and service life of structures have become the most concerned issues in the engineering field. At present, the commonly used method is to add steel fibers and organic imitation steel fibers in the concrete. in: [0003] The reinforcement effect of steel fiber on concrete to improve...
