Compression-resistant antibacterial irradiation crosslinking polyolefin foaming material as well as preparation method and application thereof
The invention belongs to the technical field of foaming materials, and particularly relates to a compression-resistant antibacterial irradiation crosslinking polyolefin foaming material as well as a preparation method and application thereof. The compression-resistant antibacterial radiation crosslinking polyolefin foaming material comprises the following components in parts by weight: 60-80 parts of low-density polyethylene, 20-40 parts of high-density polyethylene, 3-10 parts of a foaming agent, 3-5 parts of an antibacterial agent, 2-4 parts of a compatilizer, 0-2 parts of a nucleating agent and 0.2-0.5 part of an antioxidant. According to the invention, low-density polyethylene is used as matrix resin, a certain amount of high-density polyethylene and antibacterial agent are added for melt blending modification, and processes of step-by-step banburying, extrusion molding, irradiation crosslinking, step-by-step foaming and the like are combined, so that the prepared compression-resistant antibacterial irradiation crosslinking polyolefin foaming material has relatively high hardness and compressive strength; and the antibacterial cross-linked polyolefin foam material has excellent antibacterial performance, can meet the requirements of the existing market on the antibacterial cross-linked polyolefin foam material, and improves the market competitiveness.
本发明属于发泡材料技术领域，具体涉及一种抗压抗菌型辐照交联聚烯烃发泡材料及其制备方法和应用。所述抗压抗菌型辐射交联聚烯烃发泡材料，包括以下组分，以重量份计，低密度聚乙烯60～80份、高密度聚乙烯20～40份、发泡剂3～10份、抗菌剂3～5份、相容剂2～4份、成核剂0～2份和抗氧剂0.2～0.5份。本发明以低密度聚乙烯为基体树脂，通过加入一定量的高密度聚乙烯和抗菌剂进行熔融共混改性，并结合分步密炼、挤出成型、辐照交联以及分步发泡等工艺，制备得到的抗压抗菌型辐照交联聚烯烃发泡材料具有较高的硬度和抗压强度，以及优异的抗菌性能，能够满足现有市场对抗菌交联聚烯烃发泡材料的需求，提升市场竞争力。
