Abstract
The invention discloses a waterproof modified expanded perlite thermal insulation board and a production method thereof. The thermal insulation board comprises the following components, by weight: 20-30 parts of cement, 5-8 parts of fly ash, 2-5 parts of popyltrimethoxysilane, 5-10 parts of polyacrylate emulsion, 50-70 parts of modified expanded perlite, 0.7-2.9 parts of sodium dodecylbenzenesulfonate, 5-10 parts of additives, 1-3 parts of quicklime, 0.1-0.5 parts of PP fiber, 0.5-2 parts of zirconium fiber, 5-10 parts of kaolin and 10-20 parts of water. According to the modified expanded perlite thermal insulation board, cement, fly ash, kaolin, PP fiber and other organics and inorganics are adopted as raw materials, such that industrial and mining waste materials are effectively utilized, and no toxic or harmful substance is added. Therefore, the modified expanded perlite thermal insulation board is green and environment-friendly. The modified expanded perlite thermal insulation board has the advantages of wide raw material source and low cost. The production process is simple and is easy to operate. With the thermal insulation board, requirements by different building materials can be satisfied, and good social and economic benefits are provided.
Description
Technical field
The present invention relates to a kind of water proof type modified expanded perlite insulation board and production method thereof, belong to building material technical field.
Background technology
Building energy conservation is the industry that national industrial policies are given special assistance to.At present, energy-saving building materials is broadly divided into the light bone of inorganic heat preservation
Material and the light bone material of organic heat-insulating, but due to materials chemistry character, whether inorganic system or organic system, all
The requirement of properties of heat preservation and energy saving and security against fire cannot be taken into account: for heat-insulating property, organic material is better than inorganic material simultaneously；
Considering from Performance-based fire, A level anti-flammability insulation material is again only selection.In recent years, inorganic heat insulation material expands
Perlite the most progressively becomes the first-selection of inorganic external wall thermal-insulation material with its excellent fire retardancy energy, the advantage such as environmentally safe.
