Preparation method and application of cork prepolymer and construction method of cork floor
The invention discloses a preparation method and an application of a cork prepolymer and a construction method of a cork floor, and belongs to the field of cork floors. Cork or oak bark is used as a raw material to prepare cork particles, and the cork particles are treated to obtain the cork prepolymer. The preparation method comprises the following steps: stirring and mixing the cork particles and polyurethane to obtain a mixed material; carrying out baking hardening in a baking channel and normal-temperature hardening on the mixed material to harden the cork particles and the polyurethane into an agglomerated polymer; stirring, crushing and separating the polymer, adding a single-component rigid polyurethane adhesive, and uniformly stirring and mixing; after stirring is completed, carrying out baking hardening in a baking channel and normal-temperature hardening again to enable the polymer to be in an agglomerated state; and then stirring and crushing the polymer again, and crushingthe blocks into single particles to obtain the granular cork prepolymer. According to the preparation method, the cork particles are firstly treated to obtain the cork prepolymer, and the surface of the cork prepolymer is fully coated with polyurethane, so that the hardness and the impact strength of cork can be improved.
本发明公开了一种软木预聚体的制备方法及其应用和软木地面的施工方法，属于软木地面领域，以栓木或橡木树皮为原料制成软木颗粒，将软木颗粒进行处理得到软木预聚体，制备包括如下步骤：将软木颗粒和聚氨酯搅拌混合，得混合物料；将混合物料进行烘道烘烤硬化和常温硬化，使软木颗粒与聚氨酯硬化呈结块状态的聚合物；将聚合物进行搅拌破碎分离，然后加入单组分硬质聚氨酯粘合剂，搅拌混匀；搅拌完成后，再次进行烘道烘烤硬化和常温硬化使之呈结块状态；然后再次搅拌破碎，将结块打碎呈现单一颗粒状，得到颗粒状的软木预聚体。本发明先对软木颗粒进行处理，得到软木预聚体，软木预聚体的表面充分覆有聚氨酯，可以提高软木的硬度以及抗冲击强度。
