The invention discloses a preparation method for abrasion-resistant halogen-free extinction solder and belongs to the technical field of solder preparation. The preparation method comprises the steps that after being collected and ball-milled, akadama soil is mixed with tetrabutyl titanate and the like for water-bath heating, an ethanol solution is added, standing and aging are conducted, and evaporation is conducted till a mixture is dry; the dry mixture is mixed with a coupling agent for oil-bath heating, and then heat preservation is conducted, so that a filter cake is obtained through filtering; and after being cleaned, dried and ball-milled, the mixture is mixed with sodium benzoate and the like, and the abrasion-resistant halogen-free extinction solder is prepared after drying. The preparation method for the abrasion-resistant halogen-free extinction solder has the beneficial effects that the preparation steps are simple, the obtained solder is good in abrasion resistance, high in strength and long in service life, and no crack is generated after the solder is used for 10-12 years; and the airtightness is good, shadows of welding spots are bright, and the oxidation resistance and corrosion resistance are good.
