The invention discloses a blocky magnetic carpet. The carpet is divided into a base carpet layer, an EVA pre-smearing glue layer, an upper layer PVC glue layer,
glass wool cloth and a lower layer PVC magnetic glue layer from top to bottom in sequence. Meanwhile, the invention further discloses a preparing method of the carpet. The preparing method of the carpet comprises the steps of firstly smearing EVA pre-smearing glue on the back of the base carpet layer, and conducting
drying and curing to prepare a base carpet with a pre-smearing layer; then pressing the upper layer PVC layer and the lower layer PVC magnetic glue layer with the base carpet through glue formula matching and design of technological parameters and by adding the
glass wool cloth into the upper layer PVC layer and the lower layer PVC layer, delivering the upper layer PVC layer and the lower layer PVC layer into a
drying oven to conduct a plasticizing reaction for forming and block
cutting, and conducting magnetizing to prepare the magnetic square carpet. According to the preparing technology of the magnetic square carpet, the cost can be lowered by a large margin, the purpose that the size is stable is achieved, and torsion and layering do not easily occur.
