Abstract

The invention discloses a modified aeolian sand reinforced and toughened thermoplastic resin building template composition and a preparation method thereof. The modified aeolian sand reinforced and toughened thermoplastic resin building template composition comprises the following components in parts by mass: 40-70 parts of PP resin, 1-5 parts of PE resin, 30-60 parts of modified aeolian sand, 1-3 parts of a lubricant, 0.2-1 part of an anti-aging agent and 0.5-3 parts of titanium dioxide. The preparation method comprises the following steps: uniformly stirring the components, carrying out melting and extrusion through a twin-screw extruder, cooling, drying and pelletizing to obtain the modified aeolian sand reinforced and toughened thermoplastic resin building template composition. The modified aeolian sand reinforced and toughened thermoplastic resin building template disclosed by the invention is rigid and tough, high in strength, good in impact resistance and long in service life; through the application of aeolian sand, the material performance which can only be obtained by compounding and combining several fillers in the previous building template formula can be obtained, the production material management and processing operation process is simplified, and batch production is realized; and in addition, sand damage is reduced, development of other mineral resources is reduced, and the ecological environment is protected.

Description

technical field [0001] The invention relates to the field of polymer matrix building materials, in particular to a modified aeolian sand-reinforced and toughened thermoplastic resin building formwork composition and a preparation method thereof. Background technique [0002] In the field of building formwork, thermoplastic resin building formwork gradually replaces wood, metal, etc. due to its remarkable advantages such as flat and smooth board surface, good water resistance and corrosion resistance, strong machinability, recyclability, and no environmental pollution in construction applications. Building formwork is an energy-saving and environmentally friendly product. The development and promotion of thermoplastic resin building formwork has broad market prospects. [0003] Currently commercially available thermoplastic resin building templates are mainly based on thermoplastic resins such as polypropylene, polyethylene, polyvinyl chloride, and ABS, and inorganic fillers ...
