Problems solved by technology

However, the price of new carbon fiber is high, and the cost performance of the prepared carbon fiber composite building formwork is low
Chinese patent CN101538934A discloses a thermoplastic composite building formwork and its preparation process. The method adopts 8mm-30mm long glass fiber reinforced thermoplastic material to prepare building formwork. The performance of the shorter glass fiber reinforced thermoplastic material is improved, but the strength and rigidity remain the same. It is not as good as carbon fiber reinforced thermoplastic materials to prepare building templates, and the specificity is large
With the rapid development of the economy, the use of CFRP in various fields is increasing rapidly, and the waste CFRP generated is also increasing day by day. In 2019, more than 30,000 tons of CFRP were discarded globally, and the components in the waste CFRP are not biodegradable. If they are discarded directly To the environment, on the one hand, it will bring serious pollution to the environment; on the other hand, these waste CFRP often contain about 60% of high value-added carbon fibers, and the production of carbon fibers is a high energy-consuming process. Recycling will also cause a serious waste of resources

Abstract

The invention discloses a preparation method of a green regenerated carbon fiber thermoplastic material plate and a building template. The preparation method comprises the following steps of: preparing a regenerated carbon fiber thermoplastic material and preparing a regenerated carbon fiber thermoplastic composite material building template, wherein the regenerated carbon fiber thermoplastic material is prepared by hot press molding of regenerated carbon fiber non-woven felt and thermoplastic material fibers or powder; the regenerated carbon fiber thermoplastic composite material building template is prepared by preheating and mold pressing of a regenerated carbon fiber thermoplastic material sheet; regenerated carbon fibers are used as novel high-performance fibers and are obtained by pyrolysis recovery of carbon fiber composite material wastes; the regenerated carbon fiber non-woven felt is prepared from regenerated carbon fibers; and the length of regenerated carbon fiber filamentsin the regenerated carbon fiber felt reaches 50-100mm. Compared with a traditional building template, the green regenerated carbon fiber thermoplastic composite material building template has the advantages of high strength, easiness in cutting, light weight, corrosion resistance, easiness in demolding, high turnover frequency, low cost, recyclability and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of the manufacture of a recycled material building template, in particular to a preparation method of a green recycled carbon fiber thermoplastic material sheet and a building template. Background technique [0002] Building formwork is an important tool for concrete structure construction in construction engineering. At present, the building formwork commonly used in the construction field is divided into four categories: one is wood multi-layer plywood; one is steel formwork; one is bamboo sheet; the other is composite building formwork. [0003] The building formwork used in the early days was mainly wood formwork, which required a lot of wood consumption, high cost, short service life, and not easy to store. Steel formwork is also widely used, but there are also disadvantages such as high cost, high quality, inconvenient handling, and it is not easy to assemble and cut on site. Bamboo chip board formwo...
