Heat-insulating material applicable to anti-freezing road

Abstract

The invention specifically relates to a heat-insulating material applicable to an anti-freezing road, which belongs to the field of road construction. The heat-insulating material comprises, by weight, 35 to 45 parts of titanium silicate, 8 to 13 parts of aluminum oxide, 28 to 33 parts of aluminum dioxide, 6 to 10 parts of glass fiber, 6 to 10 parts of an adhesive, 0.3 to 0.7 part of a viscosity conditioning agent, 0.5 to 2 parts of a thickening agent, 0.3 to 0.7 part of an anti-oxidant and 0.3 to 0.7 part of an opacifier. The heat-insulating material provided by the invention has the following advantages compared with other conventional commercially-available heat-insulating materials: a low heat conductivity coefficient, more than four times lower than the low heat conductivity coefficient of the conventional heat-insulating materials; good temperature tolerance and capacity of long-term working at a high temperature of 150 DEG C; good thermotechnical characteristics, small specific heat, low accumulation of heat and thermal shock resistance; health, environment-friendliness and no toxicity and harm as a non-fiber material; easiness in installation and capacity of being cut, perforated and bonded; and high strength, small possibility of breakage and good toughness.

Description

Technical field [0001] The invention is the field of thermal insulation materials, which involves a insulation material suitable for anti -freezing roads. Background technique [0002] The existing commonly used road melting ice removal methods mainly include artificial or mechanical removal method and snow melting agent method. It is not ideal for snow and ice removal effects.Prevention of the road surface.The most commonly used snow melting agent will also damage the existing pavement performance, and the slow snow melting speed, low intelligence, low efficiency, and high energy consumption.The method of warming, but fast heat dissipation and poor effect, so it is also very important to carry out thermal insulation on the road body. [0003] Traditional thermal insulation materials include asbestos, diatomic soil, perlite, glass fiber, foam glass concrete, calcium silicate, polystyrene foam plastic, polyvinyl chloride foam plastic, auretic foam plastic, cork, etc.The advantages...

AI Technical Summary

Problems solved by technology

[0002] The existing commonly used road surface snow melting and deicing methods mainly include manual or mechanical removal method, snow melting agent method, etc. The effect of snow melting and deicing is not ideal, and snow can only be melted when there is ice and snow on the road surface, and it cannot be used when ice and snow accumulate on the road. prevention before pavement

The most commonly used snow-melting agent can also damage the performance of the existing road surface, and the snow-melting speed is slow, the degree of intelligence is low, the efficiency is low, and the energy consumption is large. However, the heat dissipation is fast and the effect is poor, so it is also very important to insulate the road body

[0003] Traditional insulation materials include asbestos, diatomaceous earth, perlite, glass fiber, foam glass concrete, calcium silicate, polystyrene foam, polyvinyl chloride foam, urethane foam, cork, etc. The advantages are applicable to different environments, but all the above-mentioned insulation materials have limited strength. If the above-mentioned insulation materials are added to the road body, various phenomena such as tearing and fracture will occur during construction or use. For the road body such None of the above insulation materials can be applied in the special environment of use
