Abstract

The invention relates to a PVC (polyvinyl chloride) plastic building template which comprises raw materials as follows: PVC, foaming agents, foaming regulators, wetting agents, plasticizers, stabilizers, lubricating agents, anti-impact modifiers, processing auxiliaries, reinforced fiber, hollowed glass beads, hollowed ceramic micro powder, titanium dioxide, modified resin, filling agents and the like, wherein PVC can consist of a brand new PVC material and a PVC recovered material; and the modified resin can be at least one of PP (polypropylene) and PE (polyethylene) plastic particles. The hollowed ceramic micro powder with a small particle size and the hollowed glass beads with large particle sizes are mixed for use, the flatness of the surface of the building template is remarkably improved, the secondary plastering engineering is omitted, the demolding effect is good, the mounting is convenient, time and labor are saved, and the density of the building template is not remarkably increased; the heat absorptivity of the building template is reduced and the heat resistance of the building template is improved from the angle of color design; and even if the raw materials are doped with the PVC recovered material, a light-color building template even a white building template with less heat absorption can be manufactured.

Description

technical field

[0001] The invention relates to the field of building construction templates, in particular to a polyvinyl chloride plastic building template. Background technique

[0002] Building formwork is an important tool in the construction of concrete structures. In cast-in-place concrete structure engineering, formwork engineering generally accounts for 20%-30% of the cost of concrete structure engineering, 30%-40% of engineering labor costs, and about 50% of the construction period. Formwork technology directly affects the quality, cost and benefit of engineering construction, so it is an important content to promote the progress of my country's construction technology.

[0003] Among the building formwork currently used in the market, wooden formwork, steel formwork and plastic formwork are common. Compared with the first two types, the market prospect of plastic building templates is very promising. Its advantages are: ① It can save a lot of wood; ② It has adva...
