Abstract
The invention discloses a polyethyleneimine-modified regenerated EPS particle and portland cement composite foamed warming plate. In the foamed warming plate, waste and old polystyrene foamed plastics which is cheap and is low in cost is modified to obtain regenerated EPS particles which are excellent in toughness and low in thermal expansion coefficient and resist to temperature and flame. A mixed solution of beta-cyclodextrin and polyethyleneimine is used for surface treatment of the regenerated EPS particles. Bonding strength of the regenerated EPS particles and a thick cement liquid is raised, the dispersity of the regenerated EPS particles is improved, and the rheological property of the mixed thick liquid is improved. The added raw materials including portland cement, bauxite, fine dregs of natural zeolite tailings and maize straw fiber cooperate with each other to provide a thick liquid with superior foaming performance. The prepared foamed material is high in porosity and good in heat preservation effect and has certain temperature conditioning ability. The foamed warming plate is economic and practical, is efficient and simple in production process, and has bright application prospects.
