Heat-insulating material applicable to anti-freezing road bodies and preparation method therefor

Abstract

The invention belongs to the field of heat-insulating materials and particularly relates to a heat-insulating material applicable to anti-freezing road bodies and a preparation method therefor. The heat-insulating material is prepared from the following ingredients in parts by weight: 35-45 parts of titanium silicate, 8-13 parts of aluminum oxide, 28-33 parts of alumina, 6-10 parts of glass fiber, 6-10 parts of cementing material, 0.3-0.7 part of viscosity modifier, 0.5-2 parts of thickener, 0.3-0.7 part of antioxidant and 0.3-0.7 part of opacifier. The heat-insulating material disclosed by the invention has better heat insulation and corrosion prevention effects, has extremely high strength, is not prone to breakage, can resist long-term heavy pressure, is particularly suitable for being sandwiched in the road bodies as a thermal insulating material, also has very good toughness and thus can be excellently laminated with other layers of the road bodies.

Description

technical field [0001] The invention belongs to the field of heat insulation materials, and in particular relates to a heat insulation material suitable for antifreezing road bodies and a preparation method thereof. Background technique [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. Take precautions 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. [0...

[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
