Abstract

The invention discloses a recyclable PC-ABS plastic building template, relates to the field of building templates and aims to solve the problem of poor reusability of existing building templates. Thebuilding template is technically characterized by being prepared from the following raw materials in parts by weight: 50-65 parts of polycarbonate, 45-70 parts of carbon black modified ABS plastic, 15-26 parts of alkali-free glass fiber, 8-15 parts of polydimethylsiloxane-maleic anhydride, 10-15 parts of carbon black-benzophenone, 10-16 parts of polyacrylamide-acetic acid and 10-18 parts of triphenyl phosphate. The template is reusable.

Description

technical field [0001] The invention relates to the field of building formwork, more specifically, it relates to a recyclable PC-ABS plastic building 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 to maintain their correct positions, and bear the self-weight of the building formwork and the external load acting on it. Cast-in-place The building formwork structure used in the construction of concrete structures is mainly composed of three parts: panels, supporting structures and connectors. The panels are bearing slabs that directly contact the newly poured concrete; the supporting structures are temporary structures that support the panels, concrete and construction loads. Ensure that the building formwork structure is firmly combined without deformation or ...
