一、概述随着农业科技的进步和生产的发展,农业新设施如塑料温室大棚已广为应用。全国塑料大棚面积达51万多亩,并仍以较快的速度发展。因此,塑料薄膜的耗量逐年增多。此外,农产品(如蔬菜、粮食等)广泛采用气调密封贮藏。塑料薄膜在这一领域的应用也正在发展。但由于塑料薄膜易破损,不仅影响设施的正常使用,而且增加成本,所以,迫切需要解决塑料薄膜的破损修补问题。本工作研究对聚乙烯薄膜能良好粘贴和耐老化的聚丙烯酸酯压敏胶配方及胶带制作工艺,重点探讨压敏胶老化规律及其同压敏
I. Overview With the progress of agricultural science and technology and the development of production, new agricultural facilities such as plastic greenhouse have been widely used. The national plastic greenhouse area of 510,000 mu, and still at a faster pace of development. Therefore, the consumption of plastic film increased year by year. In addition, agricultural products (such as vegetables, food, etc.) widely used atmosphere sealed storage. Plastic film in this area is also being applied. However, due to the plastic film is easily damaged, not only affect the normal use of facilities, but also increase costs, therefore, there is an urgent need to solve the problem of plastic film repair damage. This work on the polyethylene film can be good paste and anti-aging polyacrylate pressure-sensitive adhesive formula and tape production process, focusing on pressure-sensitive adhesive aging law and its pressure-sensitive
