Abstract

The invention discloses a novel anti-crack fiber and composite material preparation method. The formula comprises polypropylene, diethyl maleate, styrene, dicumyl peroxide, polyurethane resin, a reinforcing agent, an organic silicon defoaming agent and a coloring agent, and specifically 82-94 parts of polypropylene, 17-23 parts of diethyl maleate, 6-10 parts of styrene, 2-4 parts of dicumyl peroxide, 9-13 parts of polyurethane resin, 3-7 parts of the reinforcing agent, 1-3 parts of the organic silicon defoaming agent and 1-3 parts of the coloring agent in parts by weight. The composite material is used for replacing a traditional single material, the performance of the anti-crack fiber is reinforced, the use requirement of a high-strength scene is met, the application range of the anti-crack fiber is expanded, and the service life of the anti-crack fiber is prolonged; and polypropylene is subjected to grafting modification treatment in the preparation process, therefore, the performance of polypropylene is improved, and the comprehensive performance of the anti-crack fiber is improved.

Description

Technical field [0001] The present invention relates to fiber cracking technical field, and particularly for the preparation of new cracking fiber composite material. Background technique [0002] Cracking fiber is a 100% polypropylene as raw material, through a unique process and apparatus for, after melting, extruding, drawing, cutting, and other refining processes, is added to a special mortar, cement concrete can function the crack resistance of the fiber impermeability function, with its unique tensile strength, dispersibility, melting point, flash point, acid resistance and other properties, and can effectively prevent the propagation of cracks mortar, cement concrete. [0003] However, the conventional simple timber cracking fiber, low hardness and toughness, high strength can not meet the needs of the scene, limits the scope of application of the fiber cracking and corrosion resistance is insufficient, the process of using fiber serious loss, shorten the crack the life of...
