释香型实木复合地板的制备及其性能
Preparation and Performance of Fragrance-Release Engineered Wood Flooring
摘要
Abstract
To prepare fragrance-release wood flooring,two sandalwood essential oil microcapsule emulsions were added to acrylic coatings:β-cyclodextrin-microcapsule(β-CD-MC)emulsion and melamine-formaldehyde resin-microcapsule(MF-MC)emulsion.These emulsions were thoroughly mixed through physical blending process to create two distinct microcapsule coatings,which were subsequently applied to the surface of engineered wood flooring.The effects of the ratio of microcapsule emulsion,accounting for 5%,10%,15%,20%,and 25%of the coating mass,on the viscosity of the coating and the sustained-release performance were analyzed.Scanning electron microscopy(SEM)and Fourier transform infrared spectroscopy(FTIR)were employed to characterize the microscopic morphology and chemical compositions of the essential oil microcapsules,microcapsule coatings,and fragrance-release flooring products.The physical and chemical properties of the flooring were tested.Based on the viscosity test results,the optimized ratios of β-CD-MC emulsion and MF-MC emulsion were 20%and 15%,respectively,yielding viscosity values of 2 817.57 and 3 526.13 mPa·s.The SEM results present the wall structures of both types of microcapsules remain stable after dried at 60℃for 10 hours,with no significant rupture observed.These microcapsules demonstrate good compatibility with the coating and are uniformly distributed within it.FTIR results show no new characteristic peaks in the coatings with microcapsules after curing stages.It indicates that there are no chemical reactions that occurred to generate new substances,and the inherent properties of the coating remain unaffected.Aroma release tests were conducted at both 60℃and the room temperature.The results demonstrate that the fragrance-release flooring possesses excellent sustained-release property.At the high-temperature of 60℃with air-blowing,the fragrance retention time of both two fragrance-release flooring reach 96 and 104 hours,while at the room temperature ventilation condition,the retention time exceed 24 weeks.Furthermore,the adhesion,hardness,wear,and stain resistance of the coating film all meet the requirements of the National Standard GB/T 18103-2022 Engineered Wood Flooring.关键词
