Hot pressing method of PVC composite floor and PVC composite floor
The invention discloses a hot pressing method of a PVC composite floor and the PVC composite floor, and relates to the technical field of PVC composite floors. The hot-pressing method of the PVC composite floor comprises the steps that a first material layer, a first bonding layer, a PVC base plate, a second bonding layer and a second material layer which are sequentially arranged from top to bottom are subjected to hot-pressing attachment, and the first bonding layer and the second bonding layer are both hot-melt-set copolymer bonding layers; wherein the hot-pressing laminating process comprises a heating stage and a cooling stage, the temperature is gradually increased and gradually increased in the heating stage, and the temperature is gradually reduced and gradually reduced in the cooling stage. A step-by-step temperature rising and step-by-step pressure rising mode is adopted in the heating stage so as to promote heat conduction; and a gradual pressure reduction mode is adopted inthe cooling stage to ensure that the whole material reacts under the pressure condition and does not curl, so that the purpose of one-step hot pressing is achieved.
本发明公开了一种PVC复合地板的热压方法及PVC复合地板，涉及PVC复合地板技术领域。PVC复合地板的热压方法，将自上而下依次设置的第一材料层、第一粘结层、PVC基板、第二粘结层和第二材料层进行热压贴合，第一粘结层和第二粘结层均为热熔固性共聚物粘结层；热压贴合的过程包括加热阶段和冷却阶段，在加热阶段是将温度逐步升温并逐步升压，在冷却阶段是将温度逐步降温并逐步降压。在加热阶段采用逐步升温并逐步升压的方式，以促进热量传导；在冷却阶段采用逐步降压的方式，以保证整个材料在压力的条件下反应，不会出现卷曲，达到一步热压的目的。
