Beschreibung
Zusammenfassung:	The invention relates to the technical field of building templates, and provides modified desulfurized fly ash, the modified desulfurized fly ash is prepared by mixing dry-process/semi-dry-process desulfurized fly ash with a first modifier, and the first modifier is selected from one or more of polyethylene glycol, chlorinated polyethylene and polyacrylate. The invention also provides a PVC building template and a preparation method thereof. The modified desulfurized fly ash provided by the invention can be used as a filler of a skin layer of the PVC building template, the PVC building template can be reduced in density and good in dimensional stability under the condition that the original mechanical strength is ensured, the production cost of the PVC building template can be greatly reduced, comprehensive application of industrial solid wastes is realized, the mining quantity of limestone mines is reduced, and the production cost is reduced. And the environment-friendly and economic win-win situation is rea
