The present invention relates to a method for manufacturing antibacterial sand used for molding excellent in contamination resistance and cohesiveness, and more specifically the manufacturing method comprises: a releasable wax coating step (S101) for coating a releasable wax on sand an adhesive wax coating step (S103) for coating an adhesive wax mixture on the sand obtained from the releasable wax coating step an insect repellent spraying step (S105) for spraying an insect repellent on the sand obtained from the adhesive wax coating step an animal-blocking agent spraying step (S107) for spraying an animal-blocking agent on the sand obtained from the insect repellent spraying step and a cooling and selecting step (S109) for cooling and selecting the sand obtained from the animal-blocking agent spraying step. The sand manufactured through the steps has excellent cohesiveness to be suitable for molding, and is excellent in contamination resistance and antibacterial performance and, in addition, is coated with an insect repellent and an animal-blocking agent, thereby maintaining cleanliness for a long period.COPYRIGHT KIPO 2014[Reference numerals] (AA) Start (BB) End (S101) Releasable wax coating step (S103) Adhesive wax coating step (S105) Insect repellent spraying step (S107) Animal-blocking agent spraying step (S109) Cooling and selecting step본 발명은 내오염성 및 응집성이 우수한 조형용 항균모래의 제조방법에 관한 것으로, 더욱 상세하게는 모래에 이형성 왁스를 코팅하는 이형성왁스코팅단계, 상기 이형성왁스코팅단계를 거친 모래에 점착성 왁스 혼합물을 코팅하는 점착성왁스코팅단계, 상기 점착성왁스코팅단계를 거친 모래에 곤충기피제를 분무하는 곤충기피제분무단계, 상기 곤충기피제분무단계를 거친 모래에 동물접근방지제를 분무하는 동물접근방지제분무단계 및 상기 동물접근방지제분무단계를 거친 모래를 냉각 및 선별하는 냉각선별단계로 이루어진다.상기의 과정을 통해 제조된 모래는 응집성이 우수하여 조형용으로 적합하며, 내오염성 및 항균성능이 우수할 뿐만 아니라, 곤충기피제와 동물접근방지제가 코팅되어 오랜 기간 동안 청결한 상태를 유지할 수 있다.
