High-strength bamboo fiber wound composite pipe and preparation method thereof

Abstract

The invention discloses a high-strength bamboo fiber wound composite pipe and a preparation method thereof. The high-strength bamboo fiber wound composite pipe sequentially comprises a lining layer, a reinforcing layer and an outer protective layer from inside to outside, and belongs to the field of bamboo wound composite pipes. A lining layer sheet is wound around the surface of a mold roller, compacted through a pressure roller and finally cured to obtain the lining layer; a bamboo fiber lining sheet is composed of a thin film layer and a bamboo fiber layer adhered to the thin film layer, and the bamboo fiber layer is formed by adding glue into a bamboo fiber net; a bamboo fiber reinforced sheet is wound on the lining layer, compacted through the pressure roller, and cured to obtain the reinforcing layer; and outer protective layer glue is sprayed on the reinforcing layer and cured to obtain the outer protective layer. The high-strength bamboo fiber wound composite pipe has the beneficial effects that: the lining layer is composed of the thin film layer and the bamboo fiber layer, so that thin films as well as the thin films and the glue can be tightly bonded, and the added bamboo fiber layer can also improve the strength of the lining layer; and lining layer glue is coated with the thin film, and the curing thickness of the lining layer is controlled by controlling the feeding of the glue and fibers, so that the production is more convenient.

Description

technical field [0001] The invention relates to the field of bamboo winding composite pipes, in particular to a high-strength bamboo fiber winding composite pipe and a preparation method thereof. Background technique [0002] At present, in water supply and drainage projects and petrochemical anti-corrosion applications, the pipes used are generally polyvinyl chloride pipes, polyethylene pipes, glass steel pipes, glass fiber reinforced plastic sand pipes, etc. Most of the pipes have obvious advantages and disadvantages and are not environmentally friendly. Commonly used ones, such as polyvinyl chloride pipes and polyethylene pipes, are light, smooth and corrosion-resistant, but their rigidity and strength are insufficient, and the raw materials are synthetic products of petroleum products, and the products and waste materials are not recyclable. Therefore use above-mentioned pipeline product, also caused environmental pollution while consuming a large amount of precious petr...
