Problems solved by technology

Because wooden formwork is processed by cutting down trees, it takes a lot of trees to produce wooden formwork, which is not environmentally friendly
In addition, because the wooden formwork is used for a limited number of times, it needs to be replaced more frequently, resulting in a lot of waste of wood
[0003] In addition, the existing iron formwork that can replace wooden formwork is generally iron formwork, but iron formwork also has a large number of defects

Abstract

The invention belongs to the field of composite materials, and relates to a nano-calcium highly-filled polypropylene building formwork, in particular to a nano-calcium highly-filled polypropylene anti-aging building formwork and the technology thereof. The nano-calcium highly-filled polypropylene anti-aging building formwork comprises a building formwork body made of nano-calcium highly-filled polypropylene composite materials, and the nano-calcium highly-filled polypropylene composite materials comprise polypropylene plastics, polyethylene substrates, nanoscale calcium carbonate, coupling agents, a flexibilizer and an ultraviolet light absorber. The nano-calcium highly-filled polypropylene anti-aging building formwork with the technology has the advantages of being low in cost, environmentally friendly, recyclable and the like. The manufacturing technology of the nano-calcium highly-filled polypropylene building formwork comprises the steps that materials are mixed at first, melt blending forming is conducted on the mixture at the temperature ranging from 160 DEG C to 180 DEG C, an extruder conducts extruding forming, cooling and cutting, and anti-aging enhanced calcium plastic particles are obtained; the enhanced calcium plastic particles are sent to a formwork profile extruder to be extruded to form formwork profiles, and the extruded formwork profiles are cooled in a vacuum mode, pulled and cut to be the nano-calcium highly-filled polypropylene anti-aging building formwork.

Description

Technical field [0001] The invention relates to the field of composite materials, in particular to a polypropylene building template. Background technique [0002] Existing building templates often use a large number of wooden templates. Because the wooden formwork is processed by cutting down trees, the production of the wooden formwork requires a lot of trees, which is not environmentally friendly. In addition, because the wooden formwork is used for a limited number of times, it needs to be replaced more frequently, which causes a lot of wood waste. [0003] In addition, the existing iron templates that can replace the wooden templates are generally iron templates, but iron templates also have a lot of defects. Therefore, a new type of building template with the advantages of low cost, environmental protection, and reusability is needed. Summary of the invention [0004] The purpose of the present invention is to provide a nano-calcium high-filled polypropylene building templa...
