Composite board made of waste plastic and phosphorus slag fine powder and production method thereof

Abstract

The invention discloses a composite plate made of waste and old plastics and phosphorus slag fine powder and a production method thereof. The composite plate is prepared from the waste and old plastics and the phosphorus slag fine powder in a certain weight ratio through mixing, plastic extrusion and rolling. The waste and old polypropylene and waste and old polythene plastics and the phosphorus slag fine powder are used as raw materials, wherein the phosphorus slag fine powder is prepared by the method that phosphorus ores for chemical engineering industry are subjected to extraction of yellow phosphorus in a high-temperature electric furnace, and the discharged industrial waste slag and phosphorus slag are crushed, powdered and sieved so as to obtain the phosphorus slag fine powder. A proper preparation method is adopted to prepare the high-strength composite plate, so the pollution on the environment by the waste and old plastics and the phosphorus slag is reduced, and a new material is added to the building engineering. The prepared composite plate can reach the state standard of building templates, and can replace bamboo plywoods and wood building templates which are widely used in the building construction, so the effects of changing harmful materials into favorable materials and changing waste materials into valuable materials are realized, and the resource utilization process of solid waste materials in China is greatly accelerated. The composite plate has the advantages that the production cost is low, the strength is high, the shock-resistant performance is realized, the weight is light, the easy demoulding is realized, and the market prospect is better.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a building formwork and a production method thereof, in particular to a composite board made of waste plastics and phosphorus slag fine powder as raw materials and a production method thereof. 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. At the same time, 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". On the other hand, the loss of bamboo plywood and wood formwork used ...
