Abstract

The invention provides a desulfurized fly ash / PVC calendering film base material and a preparation method thereof, and belongs to the field of PVC calendering film base materials. A superfine tire vertical mill is combined with a surface modifier to form modified semi-dry desulfurized fly ash superfine powder, and then the modified semi-dry desulfurized fly ash superfine powder, general-purpose plastic, an elastic complex, a plasticizer and a stabilizer are prepared into the desulfurized fly ash / PVC calendering film base material. According to the invention, the industrial bottlenecks of high price and large primary resource consumption existing in composite modification of PVC by adopting inorganic rigid nanoparticles and elastomers are solved; a conical vertical mill and a common tire vertical mill can only be used for processing the materials until the fineness is 450 meshes and the specific surface area is 500m < 2 > / kg; the defects that ball milling energy consumption is high, processed superfine powder forms spherical morphology and does not have fiber characteristics are overcome, solid waste semi-dry desulfurization ash is fully utilized, the toughness of the calendering film base material is improved, the strength and rigidity of the calendering film base material can be guaranteed at the same time, and the industrial development requirements of energy conservation, environmental protection and circular economy at present are met.

Description

technical field [0001] The invention belongs to the field of PVC calendered film base material, and particularly relates to a desulfurized ash / PVC calendered film base material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic that is widely used. It has the advantages of low price, high strength, high modulus, flame retardancy, and corrosion resistance. However, its low notched Izod impact strength and poor thermal stability are limited. its scope of use. Traditionally, methyl methacrylate-butadiene-styrene terpolymer, chlorinated polyethylene, polyurethane elastomer, methacrylate-acrylate copolymer, etc. are commonly used to toughen PVC, but toughening will also To reduce the rigidity and strength of the material, the use of inorganic rigid particles, especially nanoparticles and elastomers to composite modified PVC can not only improve the toughness of the material, but also ensure that the strength and ...
