This embodiment 1 provides an SPC floor, including: an SPC floor comprising: the SPC floor comprises the following components in parts by weight: 70-80 parts of PVC resin and 230 parts of heavy calcium carbonate
And 14.7-20.4 parts of auxiliary agent.
Further, the auxiliary agent comprises the following components in parts by weight: 6.5-7 parts of stabilizer, 1.7-2.4 parts of lubricant, 2.5-3 parts of forming agent and 4-8 parts of toughening agent.
Specifically, the PVC resin adopts ethylene-process five-type resin powder, so that the strength and toughness are good and the PVC resin is environment-friendly; the stability of the SPC floor can be improved by the matching of the PVC resin, the toughening agent and the stabilizer.
In the embodiment, the calcium carbonate is added in a large proportion, which directly affects the formulation cost, the processing performance, the wear of the screw barrel and the product performance, so that 400-mesh and 450-mesh heavy calcium carbonate is selected.
Further, the lubricant comprises the following components in parts by weight: 0.9-1.2 parts of ZB-60 lubricant, 0.5-0.7 part of internal lubricant and 0.3-0.5 part of external lubricant.
Furthermore, the inner lubricant and the outer lubricant both adopt PE wax to meet the lubricating requirement of SPC floors.
Further, the stabilizing agent adopts a calcium zinc stabilizing agent to improve the heat stabilizing effect of the SPC floor.
Further, the forming agent adopts WY-68 type forming agent; and the toughening agent adopts RGC-135A type toughening agent.
Specifically, the plasticizing is assisted by a forming agent, and certain strength of a melt is ensured.
Specifically, the SPC flooring requires not only low shrinkage, good rigidity, but also certain toughness, ensures the firmness of the locking, does not soften at high temperatures, and maintains certain toughness at low temperatures. The traditional CPE toughening agent has good toughness, but the rigidity is poor under the condition of large addition part, the heat-resistant Vicat temperature is reduced, and the shrinkage rate is increased. The toughening agent adopted by the embodiment is the RGC-135A chlorinated polyethylene toughening agent grafted with rigid groups on the basis of the original CPE135A, so that the low-temperature toughness of the CPE is maintained, the rigidity is increased, the heat-resistant Vicat temperature is increased, the toughening agent does not soften at high temperature, the defects of the original CPE135A are overcome, and the plasticization and the flowing can be assisted.
