Problems solved by technology

[0002] At present, the thermal insulation materials used in the market mainly include perlite blocks, color steel plates, polystyrene foam boards, etc. These various products have certain technical problems. The cost of perlite block products is relatively low, but this product Water absorption and swelling, high energy consumption, color steel plate, high cost, and rain noise is loud, rust life is short, polystyrene foam heat insulation, high cost, low compressive strength, polystyrene foam board and its upper and lower The cement concrete layer is not bonded, and the service life is short. Through the patent search of the existing technology, it is found that the invention patent number (02138293.X) records a polystyrene foam concrete insulation material and its preparation method, in which waste poly

Abstract

The invention discloses a waste foam concrete insulation material and a preparation method thereof. The waste foam concrete insulation material is characterized by comprising the following components in percentage by mass: 5-15 percent of polystyrene granule with particle size of 2-10mm, 20-50 percent of cement, 15-25 percent of aggregate, 0.2-3 percent of function modifier and 4-7 percent of water, wherein the function modifier comprises a foaming agent, a foam stabilizer, a water reducing agent, an early strength agent and a coagulant, the foaming agent can be sodium dodecyl benzene sulfonate, the foam stabilizer can be arachidic acid or triethanolamine, the water reducing agent can be polycarboxylate or calcium lignosulphonate, the early strength agent can be sodium silicate, and the coagulant can be calcium chloride. The waste foam concrete insulation material is mainly prepared from waste polystyrene foam, and thus the recycling rate of waste can be effectively increased, energy resources are saved and the environment is protected.
