Abstract

The invention discloses a rubber powder material, a rubber powder polyphenyl granule, a heat-insulating material and preparation methods thereof. The rubber powder material comprises the following raw materials: 70.77-76.77% of cement, 10.8-16.08% of fly ash, 7.8-13.8% of additive and 0.10-0.15% of polypropylene chopped fiber, wherein the additive comprises the following components in percentage by weight: 2.5-4.0% of hydroxypropyl methylcellulose ether, 40.0-42.0% of smectite and / or lime, 3.6-4.5% of silicon powder, 40.0-42.0% of wood fiber, 10.0-12.0% of vinyl acetate-ethylene copolymer powder, 0.2-0.3% of starch ether and 1.3-1.5% of water repellent. The rubber powder polyphenyl granule heat-insulating material disclosed by the invention is low in heat conductivity coefficient, low in water absorptivity, high in combustion performance level and high in fire safety.

Description

technical field [0001] The invention relates to the field of thermal insulation materials for building exterior walls, in particular to a rubber powder material, rubber powder polystyrene particles, thermal insulation material and a preparation method thereof. Background technique [0002] At present, in the building energy-saving market, the system materials used in the external wall insulation system include: molded polystyrene board (EPS), extruded polystyrene board (XPS) and polystyrene particle insulation system. When using molded polystyrene board (EPS) and extruded polystyrene board (XPS) systems, cement-based or gypsum-based adhesives and plastering mortar are generally used to paste the insulation board and protect the surface layer. The polystyrene particle thermal insulation system also has two types of cement-based and gypsum-based, and a small amount of vitrified microbead inorganic thermal insulation mortar system. [0003] The current patents on polystyrene p...
