Abstract
The invention discloses a formula of a plastic building template. The building template is prepared by the following raw materials by weight: 100 parts of polyvinyl chloride PVC, 3-4 parts of heat stabilizer, 8-12 parts of chlorinated polyethylene CPE, 1.5-2.5 parts of ACR processing aid, 10-20 parts of light calcium and 2-3 parts of titanium dioxide. The plastic building template prepared by theformula has the following advantages of being (1) light in weight; (2) convenient to construct; (3) ultralow in cost and multiple in recycling times; (4) low in cost of mobilization and transition; (5) good in stability, high in bearing capability, cold-resistant, heat-resistant, free of deformation and good in flame retardant performance; (6) vertical and flat and capable of achieving a smooth wall body and serving as a clear water concrete panel; (7) capable of being reused, environmentally friendly, clean and high in plastic residual value.
Description
technical field [0001] The invention relates to the technical field of templates, in particular to a formula for plastic building templates. Background technique [0002] Building formwork is an indispensable appliance in building construction. Existing building templates include steel templates, wooden templates, and bamboo templates. Among them, the steel formwork has high strength, good finish, and strong wear resistance, but its production cost is high, and a large number of steel fasteners are required for installation. It is easy to bond with concrete and requires a large amount of release agent. The labor intensity is high; although the wood formwork and bamboo formwork are relatively cheap in cost and the finish is acceptable, they are not strong enough, have poor corrosion resistance, acid resistance, and wear resistance. Moreover, when they are unloaded, they are severely damaged due to the expansion and deformation of the wood board when it absorbs water, and the...
