摘要

墙纸广泛应用于室内装饰，但墙纸中广泛使用的淀粉基胶粘剂的易燃性和易发霉性是制约其应用的主要问题。本研究以水解淀粉（HSt）为碳源，植酸（PA）为酸源，哌嗪（PI）为气源，采用生物基三源集成阻燃剂（HSt- papi）作为淀粉粘合剂，制备了环境友好型木墙纸。采用植酸与哌嗪离子反应合成植酸哌嗪（PAPI），再引入水解淀粉制备HSt-PAPI。为配合壁纸中淀粉胶粘剂的环保性，选用天然防霉剂柠檬醛（CT）、肉桂醛（CA）、茶多酚（TP）、壳聚糖银（CS-Ag）等提高其防霉性能。结果表明，当HSt-PAPI添加量为30 wt%时，墙纸的UL-94达到V-0级，极限氧指数（LOI）达到36.6 %，总燃烧热（PCS）达到14.88 MJ/kg。在抗霉试验中，CS-Ag和肉桂醛（CA）浓度均为3 %时，其抗霉性均超过75 %。抑制带大于7 mm。本研究为多功能室内木质墙纸装饰材料的制造提供了一条环保、可持续的途径。

Environmentally friendly starch-based wood wallpaper with simultaneously flame-retardant and mildew-resistant properties

Wallpaper is widely used in indoor decoration, but its flammability and susceptibility to mold caused by the starch-based adhesive widely used in wallpaper is a major problem restricting its application. In this study, environmental friendly Wood Wallpaper was prepared by starch adhesive incorporated with bio-based three-source-integration flame retardant (HSt-PAPI) which was integrated with hydrolyzed starch (HSt) as carbon source, phytic acid (PA) as acid source and piperazine (PI) as gas source. The HSt-PAPI was prepared by synthesizing piperazine phytate (PAPI) through an ionic reaction between phytic acid and piperazine, followed by the introduction of hydrolyzed starch. To be compatible with the eco-friendliness of starch adhesive employed in wallpaper, natural anti-mildew agents like citral (CT), cinnamaldehyde (CA), tea polyphenol (TP) and chitosan-Ag (CS-Ag) were selected to improve the mildew resistance properties. The results indicated that with 30 wt% addition of HSt-PAPI, the wallpaper could achieve V-0 grade of UL-94, 36.6 % of LOI (Limiting Oxygen Index) and 14.88 MJ/kg of gross heat of combustion (PCS). In the mildew resistant test, with 3 % concentration for both CS-Ag and cinnamaldehyde (CA), the mildew resistance was exceeded 75 %. The inhibition zone was greater than 7 mm. This research provides an environmentally friendly and sustainable route for the fabrication of multi-functional interior wood wallpaper decorative materials.

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
