Preparation of Melamine-Formaldehyde Resin/Rice Husk Powder Coated Epoxy Resin Microcapsules and Effects of Different Microcapsule Contents on the Properties of Waterborne Coatings on Tilia europaea Surface

With the development of economy and science technology, people put forward higher standards for performance surface coating wood products, which requires us to carry out innovative research on coating. In this work, a kind microcapsule was prepared with melamine-formaldehyde resin/rice husk powder as wall material epoxy resin core material. The microcapsules were added waterborne acrylic according contents 0%, 1.0%, 4.0%, 7.0%, 10.0%, 13.0%, 16.0% 20.0% respectively, coated Tilia europaea boards in form topcoat. effects different optical properties, mechanical properties aging resistance explored, optimal content that can effectively improve analyzed. Test results indicated when is comprehensive optimal. At time, color difference 6.96, gloss at 60° 13.4%, hardness 2H, adhesion grade 1, impact 12.0 kg·cm. After test, loss rate decreases, 5.69, 11.6%. test show has certain self-healing function. study, optimize prolong service life prepared. This meet diverse needs consumers, supply theoretical reference preparation functional microcapsules, provide value furniture surface.
