Method for manufacturing novel material floor keel by utilizing wastes

Abstract

The invention relates to a method for manufacturing a novel material floor keel by utilizing wastes. The method is characterized by comprising the following steps: selecting 8% of attapulgite waste residue with the granularity of 80-200 meshes, 10% of fly ash, 3% of straw, 7% of mineral slag, 5% of sludge from a paper plant, 7% of waste plastic (bags) and 10% of perlite as raw materials; selecting 10% of cement, 5% of lime, 2% of talc powder and 3% of gypsum powder as auxiliary materials; selecting 2% of 50-100mm glass fiber yarn as aggregate; mixing the raw materials, the auxiliary materials and the aggregrate with 28% of magnesium chloride liquid material so as to prepare a slurry; and after mixing and soaking for 8-24 hours, stirring, discharging by a mold plate and drying, thus obtaining profile floor keel (1). The novel material manufactured by the method disclosed by the invention has the characteristics of low cost, high strength, waterproof and fireproof properties and capability of being cut and processed randomly. The novel material floor keel is of an environmentally-friendly product in the real sense.

Description

technical field [0001] The invention relates to a method for manufacturing a floor keel of a new material by utilizing waste such as fly ash, straw, slag and the like. Background technique [0002] Most of the floor joists used for decoration are wooden squares. During the construction, moisture-proof agent and insect repellant should be spread under the floor. Not only is it time-consuming and troublesome, but the life span is short, because the deformation of the keel will also affect the deformation of the floor. [0003] The circular economy promotes the widespread utilization of various wastes. Such as using fly ash to burn bricks; using shavings and wood chips to make large core boards; using slag to make cement and so on. [0004] The above-mentioned new materials made from waste materials generally cannot be used as load-bearing walls due to their high cost and low strength, poor waterproof and fireproof performance, inability to hold nails or insufficient nail ho...

Problems solved by technology

[0004] The above-mentioned new materials made of waste materials are generally unable to be used as load-bearing walls due to their high cost and low strength, poor waterproof and fireproof performance, inability to hold nails or insufficient nail holding power, and some cannot be cut and processed arbitrarily.
