Embodiment 1

[0056] A kind of loofah charcoal powder of the present embodiment, the preparation method is as follows:

[0057] (1) Preparation of loofah powder:

[0058] Take the dried loofah processing residue (the discarded loofah scraps from the natural columnar loofah processing process) and clean it; after cleaning to remove dust and a small amount of residual loofah seeds, put it in a drying oven at 80°C and dry it to constant weight. Pulverize with a high-speed pulverizer again, sieve and collect loofah powder with 60 mesh standard inspection sieves.

[0059] (2) Activation of loofah:

[0060] The loofah powder obtained in (1) is mixed with an activator in a ratio of 1:2 (the activator is ZnCl 2 with AlCl 3 According to the mass ratio of 1:1 mixed molten salt), and placed on a magnetic stirrer to stir for 5h, vacuum filtration and separation.

[0061] (3) Preparation of loofah charcoal powder:

[0062] ① Fill the activated loofah powder into the quartz boat, send it into the tu...

Abstract

The invention provides loofah sponge charcoal powder. A preparation method of the loofah sponge charcoal powder comprises the steps of treating loofah sponge treatment residues to obtain loofah sponge powder; activating loofah sponge powder by adopting a molten salt activating agent consisting of ZnCl2 and AlCl3, and carrying out high-temperature carbonization treatment on the activated loofah sponge powder; and cooling to room temperature, cleaning the loofah sponge charcoal powder, carrying out vacuum suction filtration, washing the loofah sponge charcoal powder to be neutral, and drying. The invention further provides a loofah sponge charcoal-based foam material which is obtained by mixing and foaming the loofah sponge charcoal powder and a foaming preparation, and the material can be used as a pillow inner. The invention also provides a loofah sponge charcoal memory sponge pillow. The adopted loofah sponge is loofah sponge treatment residues, and the utilization rate of the loofah sponge can be effectively increased; moreover, the loofah sponge is activated by adopting the molten salt activating agent, so that the foaming effect of loofah sponge charcoal and the foaming preparation can be improved, and the memory foam sponge material and the pillow which are antibacterial, sleep-aiding and good in moisture dissipation property and have the effects of tear resistance and yellowing resistance are further obtained.

Description

technical field [0001] The invention relates to the field of bedding, in particular to a loofah charcoal powder, a loofah charcoal-based foaming material, an application thereof, and a pillow. Background technique [0002] At present, the common pillow filling materials on the market are mainly memory foam, latex, and plant filling materials (such as buckwheat, cassia, and tea). It is poor in sex and moisture dissipation, and the sweat and water vapor produced by the human body during sleep cannot be eliminated in time. People are prone to stickiness and stuffy feeling, which affects the quality of sleep. At the same time, pillows with poor air permeability and moisture dissipation are also prone to breed mites and other bacteria, causing damage to the skin and other parts. In addition, the traditional memory foam is also prone to tearing and yellowing, which greatly reduces the service life of the memory foam material. [0003] The loofah is the vascular bundle of the mat...
