Problems solved by technology

On the other hand, because polystyrene foam particles are processed from organic matter, in actual construction, the bonding strength is low, the bonding time is short, easy to fall off, and the waste is difficult to handle and degrade, so it becomes a white pollution that endangers the atmosphere and groundwater environment. At the same time, harmful substances in polystyrene foam particles are gradually released. As an indoor insulation material, it will cause harm to the human body. It is flammable during use, has a low ignition point, poor fire resistance, and produces harmful gases at high temperatures. Cracks, shrinkage and other phenomena occur; perlite is in an open state, with large expansion volume and thin wall, and the thermal insulation mortar made of it has a large water absorption rate, high breakage rate, poor thermal conductivity, and poor crack resistance, and its application has great limitations. The thermal conductivity is 0.07-0.08W / m.k; the energy-saving effect is poor, and the thermal performance needs to be further improved

Description

technical field [0001] The invention relates to a preparation method for making waterproof, antifouling, environment-friendly, A-level flame-retardant and heat-insulating mortar with closed-cell puffed microspheres, and belongs to the technical field of heat-insulation materials for interior and exterior walls of buildings. Background technique [0002] At present, there are many kinds of thermal insulation mortar for walls at home and abroad. Most of the thermal insulation mortars are processed by organic synthesis methods. Commonly, polystyrene foam particles are used as light aggregates, and inorganic gelling materials are used as binders. It has excellent heat insulation and chemical corrosion resistance, and it is a closed-cell hydrophobic structure that does not absorb water. It has the advantages of toughness, water resistance and fiber toughening. It has the characteristics of crack resistance, good thermal performance and low engineering cost. It can be used for ext...
