Polystyrene foam grain light-weight aggregate and preparation method thereof
The invention discloses a polystyrene foam grain light-weight aggregate and a preparation method thereof. The polystyrene foam grain light-weight aggregate is prepared from the following raw materials: polystyrene foam grains, E44 epoxy resin, T31, dibutyl ester and acetone. The preparation method comprises the following steps: weighing polystyrene foam grains, E44 epoxy resin, T31, acetone and dibutyl ester according to the mass ratio of 1: (2.5-3): (2-3): (0.25-0.3): (0.25-0.3) for later use; sequentially adding T31, acetone and dibutyl ester into E44 epoxy resin to prepare an epoxy resin adhesive; then pouring the prepared epoxy resin adhesive into the polystyrene foam grains, and uniformly stirring to obtain the polystyrene foam grain light-weight aggregate. The prepared polystyrene foam grain light-weight aggregate has the characteristic of light weight, overcomes the shortcoming that the surface cohesive force between the polystyrene foam grains and a binding material is relatively poor, is extremely low in water absorption and relatively good in service durability, and facilitates reclamation and utilization of waste polystyrene foam.
