Embodiment Construction

[0026] Below in conjunction with embodiment the present invention is described in further detail.

[0027] 1. Raw materials

[0028] (1) Discarded walnut shells: pickled, dried and ground, passed through a 0.63mm sieve, and then physically activated. After activation, the pore size distribution of the walnut shells was concentrated at 10 4 nm~10 5 nm, the porosity is as high as 76%.

[0029] (2) Phase change material: paraffin or lauryl alcohol; paraffin: solid, melting point 45°C-48°C; lauryl alcohol: liquid, melting point 20°C-24°C.

[0030] 2. Walnut shell activation system

[0031]

[0032] 3. The best adsorption ratio

[0033]

[0034] A method for preparing a biomass porous phase change temperature and humidity control material, comprising the following steps:

[0035] 1) Pickling the walnut shell raw material and drying it at 105°C for 24 hours. Take the dried walnut shell raw material, put it into a ball mill, and mill it for 6 hours, then use a vibration m...

Abstract

The invention discloses a biomass porous phase change temperature adjustment and humidifying material and a preparation method thereof. The biomass porous phase change temperature adjustment and humidifying material is prepared by mixing a porous phase change material and a base material according to the mass ratio of 50:50; the porous phase change material is composed of a phase change material and a porous material according to the mass ratio of 4:6; the base material is a building gypsum plaster cementing material; the phase change material is paraffin or dodecyl alcohol; the porous material is walnut shell subjected to physical activation. The biomass porous phase change temperature adjustment and humidifying material, provided by the invention, compared with conventional phase change materials, can utilize porous phase change to realize temperature adjustment for the material, can utilize pores in the plaster adsorption to perform humidifying; the wasted shell is used as the raw material, the variety of building multifunctional materials are increased, the application range of biomass material is enlarged, and great significance is brought for the fields of improving indoor living environment and environmental protection and energy saving.
