Study on Preparation and Properties of Fiber Polyurethane Foam for Building Decoration
In order to improve the performance of polyurethane foam for building decoration,corn straw fiber was added to the traditional polyurethane foam composite for modification.Based on the compression strength,tensile strength,thermal conductivity and aging resistance tests,the mechanical properties,thermal insulation performance and durability of fiber polyurethane foam composite were systematically studied.The results showed that with the increase of straw fiber content,the compression strength and tensile strength of polyurethane foam first increased and then decreased,while the thermal conductivity first decreased and then increased.Adding appropriate straw fiber can improve the mechanical properties and thermal insulation property of polyurethane foam,but excessive fiber will weaken the mechanical strength and thermal insulation property of the foam.It is suggested that the optimal amount of straw fiber should be 8%.Adding straw fiber can reduce the aging rate of polyurethane foam and enhance the aging resistance of polyfoam.
