The present invention discloses a method for preparation of architectural interface mortar by using yellow phosphorus slag particles. The preparation method is as below: uniformly mixing and stirring 40-50 parts by weight of cement, 45-60 parts by weight of yellow phosphorus slag particles, 1.0-1.5 parts by weight of a JN-2 compound additive to obtain a dry sand; and adding water into the dry sand on the site to obtain the interface mortar. The present invention not only solves the shortage of sand resources for construction, but also solves the problem of industrial waste pollution in the production of yellow phosphorus. The method reduces the production costs of interface mortar, reduces the amount of machine-made sand, helps to reduce mining of machine-made sand, reduces environmental pollution and destruction in the rock mining process, and turns waste and harm into treasure and good. The standard state tensile bond strength of the interface mortar can achieve 0.7-1.2MPa, can be used in plastering base la
