Problems solved by technology

(3) Ordinary brick wall: This kind of wall has heat conduction, heat absorption and heat storage capacity between the former two, but the construction cost is high, and it occupies a large area of ​​land, the service life is short, and the heat preservation effect is poor. Frequent maintenance
The quality of the aluminum foil structure is only one ten-thousandth of the mass of the brick wall structure, and 8% of the mass of the foam plastic structure. 29%; Aluminum foil insulation materials can be made into various prefabricated parts, which is convenient for construction, but its production cost is too high, so it is not easy to popularize and apply in the construction of greenhouse walls

Embodiment 1

[0025] A heat storage material, which is composed of an outer heat insulation layer, a middle heat storage layer, and an inner surface breathable and water permeable layer. The outer heat insulation layer is a heat insulation material; the middle heat storage layer is made of It is composed of materials with functions of air permeability, water permeability, toughness, rigidity, water storage and heat storage; the inner surface air-permeable and water-permeable layer is composed of materials with good air permeability and water permeability.

Embodiment 2

[0027] A plant straw heat storage material, see ( Figure 1~2 ), it is composed of outer heat insulation layer, middle heat storage layer and inner surface air permeable layer, described outer heat insulation layer 1 is 15mm in thickness; described middle heat storage layer 2 is made of plant straw After pulverization, it is fully fermented to decompose the sugar contained in it, and after forming the base material, the mixture formed by mixing the base material and the binder is pressed into a heat storage wall with a stable density of 100mm and a thickness of 100mm, and is pressed on the surface. A number of cylindrical heat storage holes 4 with a diameter of 10mm are distributed in a honeycomb shape, and the depth is less than the thickness of the wall block, see ( image 3 ); the air permeable and water permeable layer of the inner surface is a sponge with a thickness of 1 mm.

Embodiment 3

Abstract

The invention discloses a heat-storing material, which consists of an outer surface heat insulation layer, a middle heat storage layer and an inner surface air-water permeable layer. The outer surface heat insulation layer is made of a heat insulation material; the middle heat storage layer is made of a material with the functions of air permeability, water permeability, flexibility, rigidity, water storage and heat storage; and the inner surface air-water permeable layer is made of a material with good air permeability and water permeability. The heat-storing material has the advantages of strong heat storage capability, poor heat conduction capability, low construction cost and convenient dismantlement, is an energy-saving and environment-friendly material, and is convenient to popularize and apply to construction of greenhouse walls.

Description

technical field [0001] The invention relates to a heat storage material, in particular to a heat storage material produced by utilizing plant straws. Background technique [0002] At present, in the construction of solar greenhouses, the walls are mainly used: 1. Single hollow wall, (1) rammed clay wall: This kind of wall has strong heat absorption and heat storage capacity, low construction cost, but large thermal conductivity. . (2) Grassed clay wall: This kind of wall has poor thermal conductivity, low construction cost, and strong heat absorption and heat storage capacity. (3) Ordinary brick wall: This kind of wall has a thermal conductivity, heat absorption and heat storage capacity between the first two, but the construction cost is high, and the land occupation is large, the service life is short, and the thermal insulation effect is poor. Frequent maintenance. 2. Heterogeneous composite wall: (1) The inner and outer layers are brick masonry, and the middle interla...
