The application discloses a high water pressure resistant, low temperature flexible waterproof and moisture permeable composite fabric and a preparation method thereof. The modified nano silicon dioxide has a nano scale effect, can efficiently shield ultraviolet radiation, and has chemical stability, endowing the material with inherent ability to resist external salt corrosion, and builds a double barrier of resistance to ultraviolet and salt corrosion in the fiber. The micro-nano surface topology of the pine needle shell layer increases the effective exposed area of the modified nano silicon dioxide, optimizes the functional interface, and the axial hollow cavity forms a stress buffer channel in the fiber, reduces the damage of external mechanical stress to the modified nano silicon dioxide dispersion structure to maintain uniform distribution. The high efficiency shielding and chemical resistance of the modified nano silicon dioxide resist ultraviolet penetration and salt erosion, and the micro-nano structure and hollow cavity of the pine needle shell layer maintain low temperature flexibility, and realize the balance of high water pressure resistance, waterproof and moisture permeability and resistance to ultraviolet and salt corrosion.

The present application relates to the technical field of paint, in particular to an alkali-resistant waterproof exterior wall paint and a preparation method thereof. In order to further improve the water resistance and alkali resistance of the stone-like paint, the stone-like paint is improved, a texture protective paint is added to the structure of the traditional stone-like paint, and colored sand is added to the components, so that a concave-convex texture can be provided for the surface of the stone-like paint after the stone-like paint is finally formed. In addition, boron nitride nanosheets are added to the texture protective paint and modified, and fluorine and silicon elements are introduced into the boron nitride nanosheets, so as to improve the chemical corrosion resistance of the resin, prevent the infiltration and invasion of external corrosive media, and effectively improve the acid and alkali resistance of the resin paint.

The application discloses a kind of polypropylene coating and preparation method thereof, belong to polypropylene coating technical field, first by photo-induced mercapto-alkene reaction preparation amino tung oil acid, again by template method copolycondensation synthesis mesoporous organosilica amino tung oil acid, simultaneously polypropylene and trifluoroethyl methacrylate melt grafting obtains TFEMA grafted modified polypropylene, finally with xylene as solvent, bismaleimide is used as crosslinking agent, and each component is blended to obtain polypropylene coating;The application is endowed with low surface energy and weathering stability by introducing fluorine-containing group to coating, combined with the ultraviolet shielding function of mesoporous organosilica, supplemented by BMI dynamic reversible crosslinking to build strong adhesion and self-repairing network, synergistically solve the technical problems that traditional polypropylene coating is poor in ultraviolet stability, weak in adhesion, and easy to age, significantly improve the outdoor durability, self-repairing and corrosion resistance of coating, and be applicable to outdoor building materials, automobile shell and other high-end protection fields with strict durability requirements.
