Abstract

The invention discloses a composite board produced from modified phosphorus slag and waste plastics and a production method thereof. According to the invention, waste polypropylene or polyethylene plastics and industrial waste phosphorus slag are taken as major raw materials, and formed into high strength composite board by an appropriate preparation method; as a result, pollution on environment caused by the waste plastics and phosphorus slag is reduced and a new material is added to the constructional engineering; the new material is capable of substituting for bamboo plywoods and wood building templates which are widely used in building operations. Furthermore, a coupling agent isopropyl trioctylpyrophosphatotitanate or isopropyl trioleyl titanate is utilized to modify the surface of the phosphorus slag so that the surface property of the phosphorus slag is changed from hydrophily into lipophilicity; the modified phosphorus slag has excellent dispersing performance in an organic phase, so that the blending compatibility and combinability of the modified phosphorus slag with the waste plastics are greatly improved; consequently, the performance of the composite board is improved.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a building formwork used in pouring concrete, in particular to a composite board made of modified phosphorus slag and waste plastics and a production method thereof, and also relates to a kind of Modified phosphorus slag for plastic filler and its preparation method. Background technique [0002] At present, the annual discharge of industrial waste phosphorus slag by my country's chemical industry is increasing year by year. In addition to being mostly used to produce phosphorus slag bricks, gypsum boards, and compound fertilizers, these phosphorus slags are currently piled in many ash storage yards for phosphorus slag. land, but also cause serious environmental pollution. In addition, with the increasing production capacity and consumption of plastic materials in my country, the output of plastic waste formed by discarded plastics is increasing, causing serious "white pollution"....
