Problems solved by technology

[0002] Currently commonly used wall thermal insulation systems, polystyrene particles, polystyrene extruded board, thermal insulation mortar, complex construction process, the load-bearing capacity of the thermal insulation layer and the fixing of the building wall rely on organic adhesives and steel nails, steel wires The fixing of the net, steel nails damage the base layer of the wall; polystyrene particles and polystyrene extruded boards have poor fire resistance, large deformability, high cost, and are prone to large-scale shedding
According to the search, the hollow vitrified microbeads and expanded perlite mentioned in the technical papers provided by Beijing Huanyimei Polymer Research Institute are light in weight, have a large blocking force during construction, and are prone to sagging, so the coating cannot be guaranteed. The thickness of batch scraping, the particles are easy to break when stirring and batch scraping, the adhesion between the wall and the slurry is not stable, it is difficult to ensure the effect of thermal insulation and long-term performance of quality

Abstract

The invention relates to hollow heat-retaining putty which is prepared by the following steps: mineral fiber, heat-response powder and base material gluing auxiliary powder are evenly mixed with a weight proportion of 1.0-2.0:0.2-0.8:89.5-137.3 to prepare the putty, ant the putty is weighted and packaged by bags. The putty overcomes the defects that the prior product has large blocking force, is easy to sag and can not ensure the blow thickness of a coat when being used in construction, the grains of the product are easy to smash when being stirred and blown, and the adhesive force is unsteady. The invention has fire resistance, heat insulation, heat preservation, sound insulation, crack resistance and yellowing resistance, steady structure, long quality guarantee period and low cost, thereby being particularly suitable for the actual need of energy saving in construction engineering.
