Definitions

  • the invention relates to a preparation method and application of a degradable composite material, in particular to a method and an application for preparing a composite material by using a drape coating technology, and belongs to the field of composite materials.
  • the coating is usually made of polyethylene (PE) or polypropylene (PP).
  • PE polyethylene
  • PP polypropylene
  • PLA polylactic acid coated coated paper
  • PLA can be naturally decomposed and non-toxic, which can achieve environmental protection effects, but PLA is brittle, tough and impact resistant.
  • the disadvantages such as poor thermal stability make the application range greatly limited, and the current PLA coating technology has certain limitations on the thickness of the coating.
  • the thickness of the PLA coating cannot be lower than 22g/m 2 , which causes the cost of PLA coating.
  • PBS polybutylene succinate
  • PLA and PBS are crystalline polymers, and their products often have certain properties. The brittleness, therefore, the scope of their application in the field of packaging is greatly limited.
  • the PBAT used in the present invention is a copolymer of butylene adipate and butylene terephthalate, which has good ductility and elongation at break, and also has good heat resistance and impact resistance.
  • PBAT is also an excellent biodegradable material, so it can be used to improve the mechanical properties of aliphatic polyesters such as PLA.
  • Xiao Yunhe et al. "Study on ultrafine calcium carbonate filled degradable polyester materials" (Plastic, 2009, 38(3): 69-71) shows that blending PBAT with ultrafine calcium carbonate can not only achieve the completion of the material.

  • the dried base material in the step I is transported to the storage bin of the laminating machine through the raw material conveyor;
  • the base material in the storage bin in the step II is heated and advanced through the feeding port into the laminating machine screw, and the laminating machine is divided into a plurality of heating segments along the screw direction, and the temperature of each heating segment gradually increases along the screw direction. Raising until reaching the melting point of the base material, and the molten base material reaches the film head of the laminating machine through the conveying elbow;
  • step IV Push the laminating machine to a certain position through the advancing guide wheel at the bottom of the laminating machine, so that the laminating machine head described in step III is located between the two rollers of the laminating machine, and then driven by the transverse cylinder.
  • the fixed sliding seat is finely adjusted, so that the film head of the laminating machine is located at a positive center line position between the two rollers of the laminating machine, and finally, the laminating machine is controlled by the pushing hydraulic cylinder to rise, so that a predetermined distance between the center line of the coating between the two rollers and the discharge opening of the shower head;
  • the base material shaft transports the substrate between the two rollers of the laminating machine table, and controls the laminating machine to coat the base material on the substrate, and controls the base by controlling the pressure between the two rollers through the transverse cylinder.
  • the composite strength between the material and the substrate, the substrate is one of paper, non-woven fabric or thin wood cardboard, and the cooling water is introduced into the roller to control the roller temperature to 20-30 ° C, Therefore, it is ensured that the molten base film can be rapidly cooled and solidified after being coated on the substrate, and the film is composited on the substrate and separated from the roller.
  • the method can successfully combine PBAT and a biodegradable mixture containing PBAT as a main component onto a substrate by a lamination method, and the obtained composite material has excellent mechanical properties and can exhibit the same performance as the PLA coated composite material. Or the above waterproof, oil-proof and temperature-resistant effects, and PBAT can be compounded to a wide thickness range, as low as 10g/m 2 , which greatly reduces the cost of the composite material.
  • the present invention can also be improved as follows.
  • step V the water spray device in the upper portion of the roller is opened while the cooling water is passed through the roller, and 10-20 ° C of water is sprayed.
  • the advantageous effect of the above further technical solution is that the base film can be rapidly cooled and solidified after being coated on the substrate, and is separated from the roller.
  • the roller is made of a release material.
  • the advantage of using the above further technical solution is that the base film can be easily separated from the roller by covering the substrate to achieve continuous production.
  • the release material is selected from the group consisting of polytetrafluoroethylene, ceramic, fluorocarbon rubber modified, and silica gel.
  • the other biodegradable plastic in the step I refers to one or a mixture of two of PLA, PBS;
  • the plurality of heating segments are 6 heating segments
  • the heating temperature of the six heating sections in the step III is increased from 150 ° C by a sequential increase of 30-40 ° C, 60-70 ° C, 10-20 ° C, 10-20 ° C, 10-20 ° C.
  • the predetermined distance between the center line between the two rollers in the step IV to the discharge opening of the dripping head is 3-7 cm.

Description

一种PBAT淋膜的复合材料的制备方法及应用 技术领域
本发明涉及一种可降解的复合材料的制备方法及应用，尤其涉及一种使用淋膜披覆技术制备复合材料的方法及应用，属于复合材料领域。
背景技术
纸质食品容器和纸质防渗漏防水防潮垃圾等容器及纸尿裤、卫生巾等为了避免液体浸渗纸材，通常会在内外表面披覆一层塑料膜，以达到防水防漏的效果，而淋膜通常使用聚乙烯(PE)或者聚丙烯(PP)为原料，这种淋膜后的纸具有了防水防漏的效果，但由于聚乙烯(PE)和聚丙烯(PP)不能生物降解，会产生大量白色垃圾，对环境造成污染。
为了解决白色污染的问题，行业内发展出一种PLA(聚乳酸)披覆的淋膜纸，PLA可自然分解，且无毒性，可达到环保效果，但PLA质脆、韧性和抗冲击性差以及热稳定性差等缺点使其应用范围大大受限，且目前的PLA淋膜技术对于淋膜的厚度具有一定的局限性，PLA的淋膜厚度不能低于22g/m2,造成PLA淋膜的成本过高，另一种可生物降解的材料PBS(聚丁二酸丁二醇酯)的加工温度低，粘性低，熔体强度差，另外，PLA、PBS是结晶聚合物，其制品往往具有一定的脆性，因此，二者在包装领域中的应用范围大大受限。
本发明中使用的PBAT是己二酸丁二醇酯和对苯二甲酸丁二醇酯的共聚物，既有良好的延展性和断裂伸长率，也具有较好的耐热性和抗冲击性，此外，PBAT还是优良的生物降解材料，因此可以用它来改善脂肪族聚酯如PLA的力学性能，肖运鹤等的“超细碳酸钙填充可降解聚酯材料的研究”(塑料，2009，38(3)：69-71)表明，PBAT与超细碳酸钙共混不仅能实现材料的完 全快速降解，还能极大的节省成本，但由于PBAT本身的物理特性粘度太大，因而在淋膜的操作过程中，极易沾附于设备之上，造成不能连续生产，因此，至今未有成功使用PBAT淋膜的报道。
发明内容
本发明针对上述PBAT淋膜过程中的问题，提供一种PBAT淋膜的复合材料的制备方法及应用。
本发明解决上述技术问题的技术方案如下：
一种PBAT淋膜的复合材料的制备方法，包括以下步骤：
Ⅰ.将PBAT或者PBAT 100重量份与其他可生物降解塑料或者超细碳酸钙5-40重量份混合后的混合物作为基料加入搅拌桶内，通过搅拌加热干燥；
Ⅱ.将所述步骤Ⅰ中干燥后的基料通过原料输送机输送至淋膜机的储料仓；
Ⅲ.所述步骤Ⅱ中储料仓中的基料经进料口进入淋膜机螺杆加热推进，淋膜机内沿螺杆方向分为多个加热段，每个加热段的温度沿螺杆方向逐渐升高直至到达基料的熔点，熔融后的基料经输料弯头到达淋膜机膜头；
Ⅳ.通过淋膜机台底部的前进导轮将淋膜机台推进至一定位置，使步骤Ⅲ中所述的淋膜机膜头位于淋膜机台的两滚轮之间，再经横向气缸驱动的固定滑座进行微调，使得所述的淋膜机膜头位于淋膜机台的两滚轮之间的正中心线位置，最后经顶推油压缸控制所述的淋膜机台上升，使得所述的两滚轮之间的淋膜中心线至淋膜头的出料口一预定的距离；
Ⅴ.基材料轴将基材输送至淋膜机台的两滚轮之间，控制淋膜机使基料淋膜披覆在基材之上，并通过横向气缸控制两滚轮间的压力来控制基料与基材之间的复合强度，所述基材为纸、无纺布或薄木纸板中的一种，同时在所述滚轴内通入冷却水将滚轴温度控制在20-30℃，从而保证熔融状态的基料膜披覆在基材上后能够快速冷却凝固，使覆膜复合在基材上并与滚轮相分离。
本发明的有益效果是：
本方法可以将PBAT及以PBAT为主要成分的可生物降解的混合物通过淋膜方法成功复合到基材上，所得复合材料与PLA淋膜的复合材料相比，具有优异的力学性能，可呈现同等或以上的防水、防油和耐温的效果，且PBAT可以复合的厚度范围大，最低至10g/m2,大大降低了复合材料的成本。
在上述技术方案的基础上，本发明还可以做如下改进。
进一步，所述步骤Ⅴ中滚轴内通入冷却水的同时开启滚轮上部的喷水装置喷出10-20℃的水。
采用上述进一步技术方案的有益效果是，能够使得基料膜覆在基材上后快速冷却凝固，并与滚轮相分离。
进一步，所述滚轮由防粘材料制成。
采用上述进一步技术方案的有益效果是，能够使得基料膜覆在基材上很容易的与滚轮相分离，实现连续生产。
进一步，所述防粘材料选自聚四氟乙烯、陶瓷、氟碳橡胶改性、硅胶中的一种。
进一步，所述步骤Ⅰ中的其他可生物降解塑料是指PLA、PBS中的一种或者两种的混合物；
进一步，所述步骤Ⅲ中多个加热段为6个加热段；
进一步，所述步骤Ⅲ中6个加热段的加热温度自150℃以依次递增30-40℃、60-70℃、10-20℃、10-20℃、10-20℃的规律增加。
进一步，所述步骤Ⅳ中两滚轮之间的中心线至淋膜头出料口的预定距离为3-7cm。
进一步，所述步骤Ⅴ中两滚轮之间的压力控制在0.5-0.8Mpa。
本发明还保护一种PBAT淋膜的复合材料的制备方法在纸尿裤、卫生巾、包装领域的应用。
