(only be 0.1W/ (mK),, can reduce the thermal conductivity of mortar because the thermal conductivity of rubber is less so the alternative a part of sand of rubber grain that tire is made is incorporated in the mortar.In addition, rubber grain is equivalent to the foam air entrapment agent, can introduce a certain amount of fine, disconnected, the micropore of remaining silent, and is dispersed in the mortar matrix, blocks or has slowed down passing through of hot-fluid.The thermal conductivity of air is very little, and heat-transfer capability is relatively poor, and itself belongs to insulating material rubber, heat conductivility difference and rubber damping are big, therefore can consume a large amount of heat energy, improve the thermal resistance of rubber grain mortar, reduce thermal conductivity, make it have certain thermal and insulating performance.Rubber grain is a resilient material, and its modular ratio mortar matrix reduces by 1000 times approximately.The interpolation of rubber grain has increased the maximum distortion limit when mortar destroys, and can absorb defective and the required energy of micro-crack extension to greatest extent, makes mortar can bear bigger stress before destruction.In addition, rubber grain can be used as the buffer zone of stress, can relax inner various stress, comprises contraction from stress, thermal stress etc., thereby reduces the generation and the development of inner primary crackle.Therefore, the adding of rubber grain not only can counter stress be concentrated and is played dissemination, and can absorb, consume a large amount of strain energies by being out of shape, and realized the conversion of energy, delay fissured time of origin, reduced fissured occurrence probability, suppressed fissured tempo.The present invention is before rubber grain substitutes sand; earlier rubber grain is carried out the interface pre-treatment with inorganic interfacial agents; after the pre-treatment; rubber grain meeting and surface treatment agent form more satisfactory interface; rubber grain and other materials after will handling stir together again; the delicate surface of rubber grain and mortar improves to a certain extent, and inorganic and organic interface adhesive property is improved, thereby and little to the intensity reduction of its mortar.Because rubber grain itself has lower thermal conductivity, excellent water tolerance and less water-intake rate, therefore can improve the heat-proof quality of mortar under the high humidity environment, secondly, because the adding of this special aggregate of rubber grain, have good distortion and alleviate inner tensile stress and make mortar have good splitting resistance, delay cracking time, better restraining effect is played in fissured development.In addition, rubber grain is carried out surface preparation, the present invention interface between rubber and the matrix cohered be enhanced and improve, and then can make the not obvious reduction of intensity of mortar, so can improve splitting resistance, intensity and the heat-insulating property under high humidity environment of thermal insulation mortar.
General traditional thermal insulation mortar porosity is bigger, and water-intake rate is very big, in the higher Working environment of the such humidity under mine, and the moisture around absorbing soon, thermal conductivity will improve significantly, loses its thermal and insulating performance soon after the thermal insulation mortar suction.It is very big that thermal insulation mortar of the present invention has overcome traditional thermal insulation mortar water-intake rate; splitting resistance is poor; weathering resistance is poor; shrinkage strain is big; easy to crack; defectives such as hollowing phenomenon easily take place; waste old is made rubber grain; carry out adding in the mortar after the pre-treatment of interface with inorganic interfacial agents; the water-intake rate of mortar is reduced greatly; when being used for this hot and humid Working environment of similar mine; can improve Working environment effectively; junked tire is called " black pollution " simultaneously; the present invention can effectively utilize junked tire to make rubber grain; be used in the thermal insulation mortar of the present invention, so the present invention has wide application prospect in environment protection and the realm of building construction.
