Abstract

The invention discloses a building material based on waste polystyrene foam plastic recovery, and relates to the technical field of the polystyrene recovery. The building material comprises the following raw material components in parts by weight: 28-32 parts of polystyrene, 20-24 parts of ethyl acetate, 11-15 parts of methylbenzene, 1-4 parts of acetone, 2.5-3 parts of a plasticizer, 0.5-1.5 parts of maleic anhydride, 8-12 parts of benzoyl peroxide, 3-4 parts of phenolic resin, 1-2 parts of 801 glue, 4-6 parts of filler, 1-5 parts of water, and 2-3 parts of an emulgator. Through a preparationmethod of the building material based on the waste polystyrene foam plastic recovery, problems existing in an adhesive directly prepared by the waste polystyrene foam plastic that the glue layer is hard and crisp, the intensity is unstable and the cost is high are solved.

Description

technical field [0001] The invention belongs to the technical field of polystyrene recycling, and in particular relates to a building material and method based on the recycling of waste polystyrene foam plastics. Background technique [0002] Polystyrene foam, referred to as PSF, is one of the most widely used plastics in the world today, because it has good water resistance, heat insulation, insulation, low moisture absorption and strong shock resistance, and it is light and strong. , easy molding, low price and other characteristics, are widely used in packaging, heat preservation, waterproof, heat insulation, shock absorption, decoration, catering and other fields. [0003] my country is a big consumer of building materials. Building materials are indispensable materials for people's life and production. Construction adhesives are indispensable materials for construction projects and have a wide range of applications. [0004] Due to the natural decomposition of polystyr...
