Plastic and solid waste combined building material and production method thereof

Abstract

The invention relates to a plastic and solid waste composite building material which comprises the following raw materials: 30-60 weight parts of plastic and 40-70 weight parts of solid waste, wherein, the plastic is one or more mixture from polyethylene, polyvinyl chloride, polypropylene, polystyrene and polyethylene terephthalate; the solid waste is one or more mixture from of furnace slag, fly ash, building material industry dust and dewatered sludge; and the building material is obtained by uniformly mixing the raw materials in proportion and delivering the raw materials to a pressing machine for press forming after the temperature is raised to 120-180 DEG C. The invention has the advantages that the sources of the raw materials are wider, washing is not required in processing, no adhesive is adopted, and the plastic raw material cannot decompose, thereby having no environmental pollution during the production process; and the product is nontoxic and odorless, and can be recycled for reuse after abrasion, no secondary pollution is caused, scraps and scrap products are all recycled and reutilized in time, and the requirements and the predominant ideas of clean production are satisfied.

Description

Technical field [0001] The invention relates to a building material and a manufacturing method thereof, in particular to a composite building material of plastic and solid waste and a manufacturing method thereof. Background technique [0002] With the improvement of people's living standards, the waste generated in daily life is also increasing, causing environmental pollution and waste of resources. For this reason, a variety of building materials made of waste have appeared in the prior art. CN1109451 discloses a foamed plastic ceramic fly ash cement lightweight wall material, which is made of 1.0-2.5 parts by weight with a particle size not greater than 10mm. Foam plastic (polystyrene) waste, 5-15 parts by weight of ceramic powder with a particle size of not more than 1mm, 20-40 parts by weight of fly ash and 100 parts by weight of cement are mixed uniformly, add appropriate amount of water to make a paste, and inject The wall material needs to use a large amount of cement, a...

Problems solved by technology

This method is only applicable to the use of cooked ceramic powder to manufacture imitation white marble building decoration materials. The heating temperature is 90-95 degrees Celsius. At this temperature, the plastic has just begun to soften and has not yet fused with other materials, so the performance of the obtained building materials is average.
