Polypropylene fiber hydrophilic modification method based on BP neural network and method for enhancing flexural strength of inorganic terrazzo by using polypropylene fiber hydrophilic modification method
The invention discloses a method for polypropylene fiber hydrophilic modification and inorganic terrazzo flexural strength enhancement based on a BP neural network, and the method comprises the following steps: 1) preparing modified polypropylene fibers by using an ultraviolet lamp and a silane coupling agent; 2) screening an optimal modification condition by using a BP neural network; and 3) the hydrophilic modified polypropylene fiber reinforced inorganic terrazzo. According to the hydrophilic modification method for the polypropylene fiber, an optimal modification condition is screened out by utilizing a BP neural network; the polypropylene fiber is irradiated through an ultraviolet grafting method, so that chains on the surface of the fiber are degraded, the surface of the polypropylene fiber is etched while carbonyl groups are generated, and the surface roughness of the polypropylene fiber is increased; the method comprises the following steps: carrying out surface hydrophilic modification on polypropylene fibers by using absolute ethyl alcohol, water and a silane coupling agent KH-570 solution by using a solution grafting method; the modified polypropylene fiber prepared by the method is excellent in hydrophilic performance, the preparation process is simple, and a new thought is provided for rapidly screening optimal modification conditions.
