但目前仍存以下缺点需要改进:
第一,传统的生产工艺步骤较多,需要多次热压及长时间的保压加工,且每次热压后的保压加工均需要保压12至24小时,传统的生产工艺所需的能耗较大,生产周期较长,生效效率较低,生产成本较高。
第二,在热压过程中,中间的塑料层无法排出存在于中部区域的空气,在完成压贴作业后,中空区域经常存在各种鼓包,严重影响复合地板的质量和寿命。
第三,由于不同材料之间的材料特征不同,其热胀冷缩系数也不相同,生产过程中不同的材料层存在不同程度的内应力,且以胶水作为粘结剂,复合地板的各个材料层之间还是容易出现分层,在复合地板投入使用一段时间后,复合地板的四周容易产生翘曲,其防水性能也非常差。

二次过胶处理,在防水基材复合层完成二次电晕处理后立即将防水基材复合层输送至过胶机,在第三电晕微孔面的表面涂布胶水,形成第二胶水复合面,以使胶水快速渗透进入以第三电晕微孔面的微型孔穴中。
复合处理,在完成二次过胶处理之后立即将经过养生处理的PVC复合层预制件3贴附在经过二次过胶处理的防水基材复合层,PVC复合层预制件3的第一电晕微孔面复合于防水基材复合层的第二胶水复合面,得到复合板材;
冷压处理,在完成复合处理后立即将复合板材输送至冷压机内,将压力调至3-15Mpa,保压4-8小时,得到复合板材原板,放置一边备用;
具体的,冷压机设置有超声冷压平台,超声冷压平台上方安装有超声冷压板,将复合板材置于超声冷压平台,控制超声冷压板向下移动并压贴于复合板材的背面,将超声冷压板的压力控制在1-10Mpa,同时开启超声发生器,在压力和超声波共同作用下,通过安装在超声冷压板上部的超声变频杆将超声波传导至超声冷压板,超声冷压板再将超声波传导至复合板材,进行超声冷压复合,使存留在带孔软垫层的内部以及上下两侧的空气通过贯穿孔22及微型孔穴排出到复合板材外部。

    c)、超声热复合子步骤,在温度、压力和超声波共同作用下,先使渗透到各软垫层(2)粉末、胶水以及存在于防水基材层(1)中的填料转变成微融状态,以形成一复合材料混合层,再使复合材料混合层在保压时固化,最终形成一所述复合材料粘结层(21),从而使带孔软垫层牢固复合在防水基材层(1)的上表面,得到防水基材复合层;
    所述软垫层(2)选用EVA片材或EVA膜材、IXPE片材、IXPE膜材、IXPP片材、IXPP膜材、PP片材、PP膜材、PVC片材、PVC膜材、软垫层(2)的中部布满贯穿孔(22);

  8. 一种防水耐磨复合地板,包括防水基材层(1)和软垫层(2),其特征在于:包括预先制作的通过热压工艺复合而成的PVC复合层预制件(3),PVC复合层预制件(3)从上往下依次包括PVC耐磨层(31)、PVC图案层(32)和PVC塑料层(33),
    经过表面电晕处理的PVC复合层预制件(3)、经过表面电晕处理的软垫层(2)和经过砂光处理的防水基材层(1)三者一同通过热压工艺复合一防水耐磨复合地板;
    PVC复合层预制件(3)的下表面和软垫层(2)的上下两个表面分别密集布满有上部具有一收缩型穴口、底部相互连通的微型孔穴;
    软垫层(2)的上表面热熔复合于PVC复合层预制件(3)、下表面热熔复合于防水基材层(1),分别在PVC复合层预制件(3)和软垫层(2)的相接表面以下的层面中形成一连成一体的网格形状的复合材料粘结层(21),在软垫层(2)和防水基材层(1)的相接表面以下的层面中形成一连成一体的网格形状的复合材料粘结层(21)。
  9. 根据权利要求8所述的一种防水耐磨复合地板,其特征在于:所述软垫层(2)选用EVA片材、EVA膜材、IXPE片材、IXPE膜材、IXPP片材、IXPP膜材、PP片材、PP膜材、PVC片材或PVC膜材,至少在软垫层(2)的中间区域布满有多个上下贯穿软件层的贯穿孔(22);软垫层(2)的四周边缘或开设槽榫(11)的位置不开设贯穿孔(22);防水耐磨复合地板的侧面设有槽榫(11),槽榫(11)仅开设在防水基材层(1)的侧面。
  10. 根据权利要求9所述的一种防水耐磨复合地板,其特征在于:所述PVC复合层预制件(3)是一PVC片材或PVC膜材,所述PVC塑料层(33)选用PVC片材或PVC膜材,PVC复合层预制件(3)的总厚度为0.5-2.5mm,PVC塑料层(33)的厚度为0.6-1.5mm;所述防水基材层(1)选用防水复合板材,防水复合板材至少包括木塑板材、石塑板材、塑料板材、防水复合木板中的一种,防水基材层(1)的底面复合有弹性层(4),弹性层(4)选用软木材料复合层、IXPE或EVA,弹性层(4)的厚度为1-5mm;防水基材层(1)的厚度为3-15mm,所述软垫层(2)的厚度为0.5-2.5mm;所述贯穿孔(22)的直径或宽度为2~20mm。
