Problems solved by technology

Rubber powder polystyrene particle insulation mortar and inorganic vitrified microbead insulation mortar have superior thermal insulation properties. The engineering insulation layer using rubber powder polystyrene particle insulation sand is relatively low in cost, but its safety performance is not high. Because it is not resistant to high temperature, Flammable, used less and less

Abstract

The invention discloses insulation mortar, prepared from, by weight, 480-520 parts of mullite powder, 540-580 parts of sepiolite powder, 15-25 parts of silica fume, 140-160 parts of kaolin, 20-30 parts of redispersible latex powder, 4-6 parts of a penetrant, 10-15 parts of asbestos wool fiber, 5-8 parts of modified polyoxyethylene, and 15-20 parts of sodium silicate powder. The mullite added herein helps increase heat capacity of the insulation mortar; kiln roof wall has less amplitude of surface temperature under same thermal barrier conditions, and the highest temperature time is extended; the insulation mortar is convenient and flexible to construct on industrial kilns, insulation dead corners are decreased, and the insulation mortar is detected to gain high strength, light weight, goodthermal insulation and good electrical insulation after using; intra-kiln heat ray in-position rate is increased, radiation heat transfer is enhanced, the diffuse disordered state is regulated into ordered state, and heat is directionally emitted to the inside of a hearth. Extra-kiln heat dissipation is lessened, so that heat preservation and energy saving are achieved; the feature that a workplace has too high temperature is improved; the insulation mortar is a simple unshaped insulation material available to many fields.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a thermal insulation mortar and a preparation method thereof. Background technique [0002] The energy-saving methods and technologies currently used in the field of industrial heating furnaces mainly include: lightweight furnace lining materials, the typical representative of which is "full fiber furnace"; regenerative industrial furnaces, which start to recover waste heat downstream of the heat flow; infrared coating technology , its fundamental weakness is the aging of the coating and the emissivity attenuation; in addition, there are protrusions to increase the furnace area; the computer distributed control method is used to improve the control accuracy, but it cannot play a fundamental role in improving the thermal efficiency of the furnace . During the heating process of the kiln, it is necessary to absorb and dissipate a large amount of heat gener...
