Abstract

The invention discloses a waterproof heat preservation material for floors of a floor heating system. The heat preservation material is prepared from the raw materials of silicon dioxide, glass fiber, porous ceramisite, cement, graphite modified expanded polystyrene, a waterproof agent, calcium hydroxide, dimethyl siloxane and water according to the mass ratios of (20 to 30) to (30 to 40) to (40 to 45) to (35 to 45) to (20 to 30) to (15 to 18) to (3 to 8) to (5 to 10) to (140 to 150). The heat preservation material disclosed by the invention combines the advantages of raw materials of various heat preservation materials, and a novel heat preservation material which is good in comprehensive technical effect, high in fire and water prevention performance and good in heat preservation effect can be provided; the heat preservation material can be used in occasions such as roof heat preservation engineering and floor heating engineering or used for manufacturing a composite heat preservation plate.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a waterproof thermal insulation material for floor heating floors. Background technique [0002] As a common basic raw material for building waterproof and fireproof materials, polystyrene has good thermal insulation performance, but its fireproof performance is low. As the most widely used and most used cementitious material in the field of building materials, the production of high alumina cement or sulfoaluminate cement has strict requirements on raw materials, requires specific technology, and has a high market price, so it is generally not suitable for use as cement. To adjust the performance of general Portland cement, ceramsite is a kind of heat preservation, heat insulation, light wall, light aggregate concrete, structural concrete, etc. in construction engineering, but due to the excavation of clay, shale, Loess, sludge, etc. will cause soil erosion, environmental pollut...
