The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present invention provides a thermal insulation material, which includes, as shown in fig. 1, a filter layer 1, a first water storage layer 2, a second water storage layer 3, and a water-repellent layer 4 that are sequentially arranged, where the filter layer 1 is used to filter saline and alkaline in water, the first water storage layer 2 and the second water storage layer 3 are used to store water filtered by the filter layer 1, and the water-repellent layer 4 is used to prevent water in the second water storage layer from permeating. When in use, the water repellent layer 4 is connected with the building wall, and the filter layer 1 is positioned at the outermost layer.

According to the heat insulation material, the filter layer 1 positioned on the outermost layer filters particulate matters in moisture, so that the probability that other layers are corroded by the matters in the moisture is reduced, and the heat insulation effect of the heat insulation material is improved. The first water storage layer 2 and the second water storage layer 3 are used for storing water, when the temperature is high, moisture in the first water storage layer 2 and the second water storage layer 3 is heated and evaporated, heat on the surface of the attached building wall is transferred, the heat is reduced from entering the building, and a heat insulation effect is achieved; when the temperature is low, the moisture in the first water storage layer 2 and the second water storage layer 3 freezes into ice, so that the heat in the building is prevented from being transferred out through the wall body, and the heat preservation effect is achieved. The water-repellent layer 4 positioned on the innermost layer prevents water stored in the first water storage layer 2 and the second water storage layer 3 from permeating into the building wall, keeps the building wall dry, reduces the breeding of organisms such as bacteria and the like, reduces the probability of mildewing, and prolongs the service life of the heat-insulating and heat-preserving material.

Preferably, the filter layer 1 is made of plant fibers by an electrospinning technique.

The filter layer 1 of the embodiment adopts plant fiber, has good biodegradability, reduces secondary pollution to the environment, and has low cost.

Preferably, the first water storage layer 2 is made of a hydrogel material and plant fibers which are interwoven. The hydrogel material can adsorb moisture, and when the temperature rises, the evaporation speed of the moisture can be slowed down, so that the effects of heat insulation and temperature regulation are achieved. Plant fibers are interwoven in the hydrogel material, so that the strength of the whole first water storage layer 2 is improved, and meanwhile, the biodegradability of the heat insulation material is improved.

Preferably, the second water storage layer 3 is made of plant fibers and is of a three-dimensional net structure, and water adsorption nano-particles are filled in the three-dimensional net structure. The water adsorption nano-particles are nano-scale hydrogel particles prepared from cellulose, and can be sodium carboxymethyl cellulose hydrogel, ionic liquid regenerated cellulose hydrogel, methyl cellulose temperature-sensitive hydrogel and the like, so that the second water storage layer 3 also has a water absorption function.

Adopt first reservoir stratum 2 and the dual water storage of second reservoir stratum 3, when the absorbed moisture of first reservoir stratum 2 was too much, can permeate into second reservoir stratum 3, second reservoir stratum 3 continues to absorb water and stores, better preventing moisture loss. During water storage, only when the first water storage layer 2 is saturated, the water slowly permeates into the second water storage layer 3 and is stored by the second water storage layer 3, so that the water storage probability of the second water storage layer 3 closer to the building wall is ensured, the building wall is kept dry, the breeding of organisms such as bacteria and the like is reduced, the mildew probability is reduced, and the service life of the heat insulation material is prolonged. When the first water storage layer 2 is not saturated, gaps are formed among the three-dimensional net structure of the second water storage layer 3 and the moisture adsorption nano particles, and the porosity of the second water storage layer 3 is high, so that the heat preservation effect of the heat insulation material is improved. When the temperature rose, first reservoir stratum 2 was heated, and the moisture that the aquogel was stored can slowly evaporate, and after the moisture of first reservoir stratum 2 all evaporated, the moisture of second reservoir stratum 3 also gradually evaporated, and the moisture of evaporation is absorbed by first reservoir stratum 2 and is stored, and then the rethread first reservoir stratum 2 is heated the evaporation to keep the invariant of temperature.

The number of the columnar support legs 5 is at least one, and the columnar support legs are used for connecting the water-repellent layer 4 and the base layer 6, so that the connection performance between the water-repellent layer 4 and the base layer 6 is improved, the layering probability is reduced, the integrity of the form of the heat-insulating material is improved, and the condition that a certain layer falls off and needs to be repaired again is avoided.

Preferably, the cylindrical legs 5 are made of metal. The columnar support leg 5 made of metal has high hardness and is not easy to deform, and the connection strength of the water repellent layer 4 and the base layer 6 is improved, so that the strength of the heat insulation material is enhanced.

Preferably, the outer part of the columnar support foot 5 is wrapped with a hydrogel column, and the outer part of the hydrogel column is wrapped with a plant fiber layer. The columnar support legs 5 are made of metal, are exposed in the air and are easy to corrode, and are wrapped by hydrogel to protect the columnar support legs 5 and reduce the probability that the columnar support legs are corroded. Still can adsorb the unable moisture that continues the absorption after the second reservoir stratum saturation, simultaneously, moisture volatilizees during high temperature, further improves thermal-insulated insulation material's aridity, reduces bacterial growing, improves the life of material. The hydrogel column is coated with a plant fiber layer to improve biodegradability.
