Abstract

The invention discloses a spontaneous-heating dehumidification material and a preparation method thereof. The spontaneous-heating dehumidification material comprises the following ingredients (by weight): 100 parts of a carrier resin material, 15-25 parts of a curing agent, 4-8 parts of edible seaweed powder, 8-16 parts of calcite, 0.4-1.2 parts of potassium carbonate micro-powder, 3-7 parts of ferronickel powder, 2-6 parts of tungsten powder, 5-10 parts of zeolite powder, 1-3 parts of carbon nanotube, 6-14 parts of white carbon black, 1-3 parts of an accelerant M, 1-4 parts of an antioxidant,5-9 parts of calcium powder, and 6-12 parts of an auxiliary agent. The spontaneous-heating dehumidification material has a good spontaneous-heating dehumidification effect, can adsorb, transport andevaporate moisture, and has a hot-melting effect on snow cover and icing conditions so as to reduce water damage of roads. In addition, the spontaneous-heating dehumidification material has a simple and convenient preparation technology, can facilitate rapid construction and earlier opening to traffic, and has a good application prospect and broad development space.

Description

Technical field [0001] The invention belongs to the technical field of road materials, and more specifically relates to a self-heating dehumidification material and a preparation method thereof. Background technique [0002] In my country, due to the comprehensive influence of various factors such as internal and external factors, water damage to asphalt pavements is widespread, especially in the rainy areas in the south and under heavy load and heavy traffic conditions, causing significant economic losses and bad society. influences. And studies have shown that the early destruction of asphalt pavement is more or less related to the presence of water, that is, the destructive effect of water is one of the key factors. Water damage refers to the repeated action of water pressure, freeze-thaw cycles and vehicle load on the asphalt pavement under the action of water. The water inside the mixture will continuously produce dynamic water pressure and repeated pumping action on it. As...
