Abstract

The invention discloses a treatment process for improving thermal expansion and cold contraction deformation of a hollow plastic template, and relates to the technical field of plastic template processing, and the treatment process specifically comprises the following steps: S1, preparation of a polymer organic framework material, S2, preparation of a composite fiber material, and S3, processing and manufacturing of the plastic template. According to the preparation method, the prepared polymer organic framework material and the composite fiber material are subjected to injection molding melting with premix particles respectively, a melt containing the polymer organic framework material is used as a middle layer of a plastic template, and the melt containing the composite fiber material ispoured on the periphery of the middle layer to form a coating layer; accordingly, a large number of independent supporting pieces which are evenly distributed are formed in the middle of the plasticformwork, the periphery of the plastic formwork is wrapped with a layer of composite fiber net, cold shrinkage deformation of the plastic formwork can be restrained through the supporting effect of the independent supporting pieces, and the composite fiber net wrapped on the periphery can restrain thermal expansion deformation of the plastic formwork. Therefore, the thermal expansion and cold contraction deformation of the plastic template can be reduced.

Description

technical field [0001] The invention belongs to the technical field of plastic formwork processing, and in particular relates to a treatment process for improving thermal expansion and cold contraction deformation of a hollow plastic formwork. Background technique [0002] The building formwork is a temporary support structure, which is manufactured according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct position, and bear the self-weight of the building formwork and the external load acting on it. At present, the building formwork on the market is mainly steel formwork or wood formwork. Among them, the steel formwork mainly has the disadvantages of high cost, heavy weight, and difficulty in hoisting, while the wood formwork mainly has the disadvantages of low rigidity, easy mold expansion, and few turnover times. [0003] For this reason, people have develop...
