The invention relates to ultralight bulletproof cloth and a manufacture method thereof, and belongs to the technical field of textile materials and protection materials. The manufacture method includes taking modified carbon fiber filaments as central core threads, taking modified ultra-high molecular weight polyethylene as a middle coating layer, taking cellulose acetate fibers as an outer coating layer, and preparing covering yarns; blending modified aramid fibers 1414, the modified ultra-high molecular weight polyethylene, graphene fibers and the cellulose acetate fibers to acquire blended yarns; spinning the covering yarns and the blended yarns into the ultralight bulletproof cloth by a spinner, wherein warp yarns are arrayed sequentially according to the principle that one covering yarn is matched with one blended yarn, and weft yarns are arrayed sequentially according to the principle that one covering yarn is matched with two blended yarns. The ultralight bulletproof cloth and the manufacture method thereof have the advantages that full polymer modified materials are adopted, and the carbon fiber framework design is introduced, so that strength, tenacity and impact resistance are high, penetration of low-speed bullets, bomb fragments and the like can be resisted effectively, and safety of human bodies can be guaranteed.

The invention relates to the technical field of building materials and discloses a polymer modified cement mortar steel fabric surface layer reinforcing structure. The polymer modified cement mortar steel fabric surface layer reinforcing structure comprises a reinforced layer; a groove is formed in the middle of the upper surface of the reinforced layer, an adhesion agent coating is fixedly connected with the upper surface of the reinforced layer, a major bearing frame of a steel fabric surface layer is fixedly connected in the groove through pins, and minor bearing frames of the steel fabric surface layer are fixedly connected with the upper surface of the adhesion agent coating; a polymer modified cement mortar coating is fixedly connected between the steel fabric surface layer and the adhesion agent coating. According to the polymer modified cement mortar steel fabric surface layer reinforcing structure, the major bearing frame and the minor bearing frames are installed, the major bearing frame is fixedly connected in the groove trough the pins, the two minor bearing frames are fixedly connected with the two sides of the lower surface of the steel fabric surface layer, and while light weight reinforcing is achieved, stability when the steel fabric surface layer is used is ensured.

The invention discloses a polymer modified carbon nanotube and a preparation method thereof. The preparation method of the carbon nanotube comprises the following steps: (1) in an aprotic organic solvent, reacting a hydroxylated carbon nanotube with an alkali metal compound or an alkali metal complex to obtain a carbon nanotube alkoxide; and (2) initiating a vinyl-containing monomer to polymerizeby using the carbon nanotube alkoxide to obtain the vinyl polymer modified carbon nanotube. The method has the advantages of simple preparation, mild reaction, safe operation and the like.
