The　influencing　factors　in　the　course　of　synthesis　of　furan　resin　modified　by　urea-formaldehyde　resin,　such　as　reaction　temperatures,　molar　ratio　of　formaldehyde　and　urea,　pH　values,　charging　ways　and　the　addition　of　modifying　agents,　have　been　studied.　Meanwhile,　a　more　proper　processing　condition　of　synthesis　of　furan　resin　with　high　water　content　has　been　found.　The　furan　resin　product　is　a　brown　transparent　liquid,　which　has　the　performance:　tensile　strength　2.28　MPa,　mass　fraction　of　water　18.9%,　mass　fraction　of　free　formaldehyde　0.23%,　viscosity　(20C)　31　mPas.
