Abstract

The invention relates to a three-dimensional fiber inorganic composite (FCC: Fiber Cement Composite) product and a production method thereof, and the three-dimensional fiber inorganic composite product comprises a decorative layer and a three-dimensional fiber-reinforced cement structure layer. The decorative layer is prepared from decorative mortar and can be subjected to fiber reinforcement; and the structure layer is prepared from the fiber with high elastic modulus, the fiber with low elastic modulus and reinforced concrete mortar in three-dimensional distribution, and 0-3 layers of reticular reinforcing material is further laid. The decorative layer and the structure layer are compounded in a mold with the decorative effect and can be prepared by adopting an integral formula and process. The product is prepared through the fiber mixing technology and the premixing and forming technology, a high-performance novel material applied to the fields of building decoration engineering, anti-cracking engineering construction, building exterior wall repair and the like is realized, the product has the advantages of light weight, high strength, high durability, anti-cracking property and the like, and fiber-reinforced exterior wall plates, decoration members and other products in complex shapes and fineness can be further manufactured. Simultaneously, as the production process is simple, the degree of mechanized production is high, the production cost is low and the range of market applications is broad.

Description

Technical field [0001] The invention relates to a three-dimensional fiber inorganic composite product (FCC) and a production method thereof, and specifically refers to a three-dimensional distribution of multiple fibers in a cement matrix to realize a high-strength and high-toughness concrete product. The product application range includes the fields of building exterior wall decoration, anti-cracking engineering construction and building exterior wall repair. Background technique [0002] Cement concrete is one of the most widely used construction materials in my country, but at the same time, during the hardening process of concrete, it is easy to produce many micro-cracks along with various shrinkage (such as chemical shrinkage, temperature shrinkage, plastic shrinkage, drying and autogenous shrinkage, etc.). A brittle material with poor toughness, unevenness and easy cracking. In my country, glass fiber can improve the tensile strength and impact resistance of concrete and is...
