Problems solved by technology

[0004] The general wall insulation system uses a single ordinary expanded perlite or EPS particles as the lightweight aggregate of the thermal insulation mortar. The expanded perlite lightweight aggregate has high water absorption, is easy to pulverize, and has a large volume loss rate during slurry construction. The product In the later stage, the strength is low, there are phenomena such as hollowing and cracking, and low thermal insulation performance; the...

Abstract

The heat insulating glue powder material for wall consists of cementing components and light aggregate. The cementing components include cement, lime, flyash, silica fume powder, re-dispersed emulsion powder, dispersed high strength high modulus PVA fiber, wood fiber, cellulose ether and water reducing agent in certain weight proportion. The light aggregate includes vitrified closed pore perlite bead and EPS grain in certain weight ration. The cementing components and the light aggregate are packed separately and in-situ mixed. The present invention has stable and reliable quality, light bulk density, high heat insulating performance, high strength, excellent construction performance and other advantages.

Description

Technical field [0001] The invention relates to a wall thermal insulation rubber powder material and a preparation method and a use method thereof. Background technique [0002] Wall insulation technology is energy-saving, anti-cracking, water-repellent and breathable, and is suitable for any new construction, renovation and expansion projects. The current wall insulation generally uses polystyrene board. Due to the thermal insulation effect of polystyrene board, the insulation system can keep warm in winter and meet the energy-saving requirements of heating buildings. In summer, it can meet the requirements of thermal insulation design. Therefore, according to the design requirements It can be used in areas that require thermal insulation in winter and summer. [0003] The building wall adopts thermal insulation technology, which has many advantages, which not only obviously improves the living comfort, but also has very good energy-saving effects and comprehensive economic bene...
