Problems solved by technology

The early building formwork was made of iron, which was heavy, expensive, inconvenient to transport, and had hidden safety hazards in construction; currently, steel-wood composite formwork is mainly used in large-scale construction projects, while wood is still used in general construction projects. Glue formwork or bamboo formwork, made of multi-layer thin wood chips glued and hot-pressed, is easy to crack after water seepage, and the number of uses is only 3 to 5 times. After a short period of use, it can only become a pile of garbage, causing great harm to the environment. big negative impact
In recent years, various types of "plastic building formwork" have appeared one after another, such as wood-plastic formwor

Abstract

The invention discloses a building template reinforced by composite of a continuous fiber plastic coated belt material, which has the advantages of favorable mechanical property and complete waterproof and dampproof properties and can be recycled more than a hundred of times. In the composite reinforced building template of the continuous fiber plastic-coated belt materials, a wooden oriented structural board is used as a core layer, a macromolecular adhesive membrane and 2-4 layers of continuous fiber plastic-coated belt materials are outwards sequentially and flatly paved and fixed on the two sides of the wooden oriented structural board symmetrically to form multilayer-combined composite reinforced building template of the continuous fiber plastic-coated belt materials, with a sandwich structure, wherein surface resin on one face of the macromolecular adhesive membrane is polypropylene resin, the surface resin on the other face of the macromolecular adhesive membrane is maleic anhydride modified polypropylene resin, a macromolecular adhesive membrane face with the surface resin of the maleic anhydride modified polypropylene resin is laminated with the wooden oriented structural board as the core layer, and a macromolecular adhesive membrane face with the surface resin of the polypropylene resin is adhered to a thermoplastic resin plastic-coated layer of the continuous fiber plastic-coated belt materials through thermal compression; and the continuous fiber plastic-coated belt materials are manufactured by coating thermoplastic resin on continuous fiber warp-knitted unidirectional cloth, and the fiber content of the continuous fiber plastic-coated belt materials is 20-60%.

Description

technical field [0001] The invention relates to a building formwork and a preparation method thereof, more specifically to a continuous fiber plastic-coated tape composite reinforced building formwork and a preparation method thereof. Background technique [0002] Common building formwork is used for concrete pouring and molding. The early building formwork was made of iron, which was heavy, expensive, inconvenient to transport, and had hidden potential safety hazards in construction; currently, steel-wood composite formwork is mainly used in large-scale construction projects, while wood is still used in general construction projects. Glue formwork or bamboo formwork, made of multi-layer thin wood chips glued and hot-pressed, is easy to crack after water seepage, and the number of uses is only 3 to 5 times. After a short period of use, it can only become a pile of garbage, causing great harm to the environment. big negative impact. In recent years, various types of "plasti...
