摘要

Two component polyurethane water dispersions (PUDs) based on 1,3-Propanediol polyester polyols (PDO Adipate 2000 and PDO Sebacate 2000) and polyether polyols (Velvetol H 2000,Allessa) were produced and applied on three uncoated fabric sources (cotton sateen,polyester duck,and textured nylon) to evaluate their performance and commercial viability.The commercial reference PUDs were based on BDO Adipate 2000 and poly(oxytetramethylene) glycol 2000 (PTMG 2000).The use of solvent-free waterborne urethane dispersions (PUDs) is widely discussed in literature and growing across various industries due to environmental factors.The introduction of 1,3-Propanediol (1,3-PDO) as a bio-based component of chain diols in polyurethanes is accepted as shown by its use on commercial scale to produce polyester and polyether polyols for various applications.Solvent-free bio-based systems must offer all the same required properties of current commercial products with the added advantage of being eco-friendly and sustainably sourced.PUDs are a desirable coating for various textile application since they provide very good tensile strength,wear resistance,have good adhesion to various substrates,and can be formulated to be moisture resistant while maintaining vapor permeable (or breathable) properties.To obtain PUDs with good performance,the effects of varying the building block components (soft and hard segments) needs to be understood.The introduction of dimethyl propionic acid (DMPA) pendant ionic groups into hard segment block facilitates the formation of stable PUDs of acceptable solids loading by increasing hydrogen bond interactions.The bio-based coatings prepared in this investigation provided useful physio-mechanical properties,chemical resistance,and water resistance compared to reference commercial petroleum based two-component (2K-PUDs) and one-component (IK-PUD) w;aterbome polyurethanes.
