Method for producing crack-resisting insulation mortar by utilizing rock wool heels

Abstract

The invention discloses a method for producing crack-resisting insulation mortar by utilizing rock wool heels. The method is characterized by comprising the following steps: based on weight parts, adding 330 parts of No.42.5 cement, 25 parts of rock wool heels, 120 parts of vitrified microspheres, 120 parts of early strength agent, 2 parts of water-retaining agent, 10 parts of rubber powder, 1 part of wood fiber, 1 part of sodium lignin and 1 part of poval-2488 in a double-shaft horizontal type stirring kettle to stir for 20 minutes at the constant speed of 300-500 r / min; and then packaging the stirred material with an automatic packaging machine. The crack-resisting insulation mortar produced by the method can be directly constructed after a main body of a building is completed; when themortar is used for insulating an outer wall, the problems of burning, cracking, falling and the like can not occur; and the service life of the insulation material is the same as that of the building, thereby saving a large amount of repair cost.

Description

technical field [0001] The invention relates to a method for producing crack-resistant and heat-preserving mortar by using rock wool leftovers, which belongs to the field of fine chemical industry. Background technique [0002] After entering the 21st century, my country's urbanization process has developed rapidly, followed by a sharp increase in energy consumption. Construction, industry, and transportation are the three major areas of energy consumption in China. Among them, construction accounts for nearly 30% of China's total energy consumption. It is estimated that In 2020, the total energy consumption of buildings accounts for 50% of the total energy consumption of the whole society, of which external wall insulation, roof insulation, and door and window heat dissipation account for 50% of the energy waste of houses. It can be seen that heating in winter and cooling in summer are a great waste of energy. In terms of building insulation performance, the energy consumpti...

Problems solved by technology

The third point is that it is easy to fall off and be damaged: most of the building insulation and energy-saving materials are organic insulation materials that have been foamed, which are light in weight and poor in hardness. There are insulation nails, some insulation boards are easy to fall off due to the quality of the adhesive and insulation nails

The fourth is easy to crack: since the insulation material is organic, most of the walls, adhesives, exterior wall putty, and exterior wall elastic coatings are inorganic materials. , it is easy to crack the wall, causing rainwater to enter, and the paint to peel and fall off
