绝缘材料在建筑环境中无处不在，在减少维持可居住的室内环境所消耗的能源方面发挥着关键作用。矿棉绝缘（MWI）产品，包括玻璃，石材和矿渣变体，是欧洲使用最广泛的绝缘材料类别，占总市场的50%以上。MWI通常由两个关键部件组成：直径为几微米的无机纤维网和通常称为“粘合剂”的有机热固性粘合剂。MWI生产中使用的传统苯酚-甲醛-尿素（PFU）粘合剂在其生产和使用寿命期间释放的甲醛越来越多地受到审查。最近各种安全组织将甲醛分类为致癌物，加速了行业内向替代粘合剂技术的范式转变，这些技术可最大限度地减少或消除甲醛排放。本文综述了最近实现MWI低添加或零添加甲醛粘合剂的策略，特别关注专利文献。介绍了传统PFU粘合剂的化学基础，并与涉及清除分子的新策略进行了比较，这些分子可减少甲醛排放，以及零添加甲醛粘合剂技术，如聚酯，美拉德和环氧热固性树脂。矿棉绝缘产品中使用的传统苯酚-甲醛-尿素粘合剂在其制造和使用寿命期间释放甲醛。本文综述了实现低甲醛或零甲醛粘合剂的最新策略，例如通过使用清除分子减少甲醛排放，以及无甲醛粘合剂，包括聚酯，美拉德和环氧热固性树脂。
Insulating materials are ubiquitous in a built environment and play a critical role in reducing the energy consumed to maintain habitable indoor environments. Mineral wool insulation (MWI) products, including glass, stone, and slag variants, are the most widely used class of insulating materials in Europe and account for more than 50% of the total market by volume. MWI typically consists of two key components: a mesh of inorganic fibers that are several micrometers in diameter, and an organic thermosetting adhesive commonly referred to as the “binder.” Traditional phenol‐formaldehyde‐urea (PFU) binders used in the manufacture of MWI are increasingly being scrutinized for the formaldehyde released during their manufacture and service lifetime. The recent classification of formaldehyde as a carcinogen by various safety organizations has accelerated a paradigm shift within the industry toward alternative binder technologies that minimize or indeed eliminate formaldehyde emissions. This review examines more recent strategies for achieving low‐ or zero‐added formaldehyde binders for MWI, with a particular focus on the patent literature. The chemistry underpinning traditional PFU binders is presented and compared to new strategies involving scavenging molecules that decrease formaldehyde emissions, as well as zero‐added formaldehyde binder technologies such as polyester, Maillard, and epoxide thermosets. Traditional phenol‐formaldehyde‐urea binders used in mineral wool insulation products release formaldehyde during their manufacture and service lifetime. This review examines recent strategies for achieving low‐ or zero‐formaldehyde binders, such as through the use of scavenging molecules that decrease formaldehyde emissions, as well as formaldehyde free binders including polyester, Maillard, and epoxide thermosets.
