The invention discloses a PP/PCTA cable material filled with biomass combustion ash and a preparation method thereof. The PP/PCTA cable material filled with the biomass combustion ash is prepared from the following raw materials in parts by weight: 45 to 55 parts of PP (Polypropylene), 20 to 40 parts of PCTA, 15 to 25 parts of biomass combustion ash, 12 to 20 parts of dimethoxyethyl phthalate, 5 to 10 parts of tetrahydrofurfuryl alcohol, 3 to 7 parts of yttrium oxalate, 10 to 5 parts of poly(propylene glycol sebacate), 7 to 11 parts of oxidized polyethlene wax, 20 to 30 parts of coal gangue, 15 to 55 parts of yellow phosphorus slag, 3 to 6 parts of Al-PTBBA, 11 to 19 parts of silica residue containing zirconium, 10 to 15 parts of natural colorful stone flour and 16 to 22 parts of fibrolite. The cable material prepared by the invention has an excellent comprehensive performance, has relatively high mechanical strength and also has good weather resistance, chemical corrosion resistance, low-temperature toughnes
