Abstract
The invention provides a hollow plastic capsule and fiber composite material and a preparation method thereof. A hollow insulation board comprises wood fiber, hollow plastic capsules and a binding agent, wherein the length of the wood fiber is 1-3mm, the diameter of the wood fiber is 0.1-0.3mm, and the diameter of the hollow plastic capsules is 0.5-8mm; and the hollow plastic capsules are bonded into a body through polyurethane glue. As the hollow plastic capsule and fiber composite material adopts the hollow plastic capsules with different grain diameters and is bonded through the environment-friendly non-toxic polyurethane glue, compared with a solid fiber board material, under the premise that mechanical properties are ensured, the density can be greatly decreased, the effects on the aspects of operational performance of sound insulation and thermal insulation, energy conservation and the like are greatly increased, and the effect that resources are saved and fully utilized is also obviously superior to that of the solid fiber board material.
