Abstract

The invention relates to a construction waste recycled artificial marble and also relate to a preparation method of the construction waste recycled artificial marble. The construction waste recycled artificial marble comprises the following components by weight: 30-70% of construction waste dust, 10-50% of construction waste recycled fine aggregate, 10-40% of unsaturated polyester resin, 2-15% of accelerant, 0.5-4% of curing agent, 0.3-4% of acrylic paint and 0.2-4% of aluminum hydroxide. The preparation method of the construction waste recycled artificial marble comprises the steps as follows: mixing; forming by pouring, pulling and drying; coloring and drying; grinding and polishing; checking quality; and warehousing finished products. According to the construction waste recycled artificial marble, a problem of resource scarcity of natural marble is solved, and remarkable social and environmental benefits are obtained; and according to the preparation method of the construction waste recycled artificial marble, the process is advanced, the technology is mature, the resources are recycled, and requirements of national recycling economy development are met.

Description

technical field [0001] The invention relates to a kind of regenerated artificial marble from construction waste, in particular to a new type of regenerated artificial marble by recycling and reusing construction waste and dust, and also relates to a preparation method of the regenerated artificial marble from construction waste. Background technique [0002] With the acceleration of urban construction and the depletion of natural sand and gravel resources, the comprehensive utilization of construction waste to prepare recycled coarse and fine aggregates can completely replace natural sand and gravel, but there is no effective way to dispose of the dust generated during the processing. Random dumping will cause secondary pollution to the environment. After the dust generated in the production of construction waste is recycled, it can be returned to the preparation process for continued use, which can basically ensure that there is no secondary pollution. Contents of the inv...
