Problems solved by technology

[0005] In the prior art, there has been no research report on the use of camphor residues to make biomass materials. We used camphor leaf residues as raw materials and found that after crushing the residues of camphor leaves, the material is loose, and the powder of camphor leaf residues is difficult to separate. The tight combination leads to poor strength and toughness of the camphor leaf residue material, which cannot meet the requirements of actual processing and production

Embodiment 1

[0051] Carry out the glue adjustment implementation process of the present invention as base-material with soybean flour as follows:

[0052] A kind of biomass material preparation method based on camphor leaf residue, comprises steps:

[0053] (1) drying: removing impurities and drying the camphor leaf residue to obtain dry camphor leaf residue;

[0054] (2) pulverizing: the dried camphor leaf slag is pulverized into camphor leaf slag powder for use;

[0055] (3) Glue adjustment: Weigh 50g of soybean powder, 1g of lignin, 0.25g of sodium hydroxide, and 200g of water. Add the soybean powder into the water and stir for 6 to 8 minutes at a heating temperature of 60-75°C. Then add lignin Stir for 8-10 minutes, then add sodium hydroxide and continue stirring for 30-40 minutes to obtain viscose.

[0056] (4) Shaping: Mix camphor leaf residue powder and viscose, knead and press at the same time, the kneading time is 15 to 30 minutes, and the product is ready.

[0057] After stirr...

Embodiment 2

[0059] Carrying out the glue adjustment implementation process of the present invention with starch as base material is as follows:

[0060] In this embodiment, the steps of drying, pulverizing and shaping based on the biomaterial preparation of camphor leaf residue are the same as in Example 1, the difference is that:

[0061] (3) Adjust glue: Weigh 50g starch, 1g lignin, 0.25g sodium hydroxide, 200g water, under the condition of heating temperature of 60-75℃, add starch into water and stir for 6-8min, then add lignin and stir 8 to 10 minutes, then add sodium hydroxide and continue stirring for 30 to 40 minutes.

[0062] During the stirring process, it was found that the starch glue is too sensitive to the temperature during the heating process, and it is easy to lose the viscous state with the temperature rise during the heating process, and at the same time lose the sticky function. Among the 10 preparations of starch glue, 6 times the mixture of starch and water did not a...

Embodiment 3

[0064] Take potassium permanganate as reinforcing agent to carry out the glue adjustment implementation process of the present invention as follows:

[0065] In this embodiment, the steps of drying, pulverizing and shaping based on the biomaterial preparation of camphor leaf residue are the same as in Example 1, the difference is that:

[0066] (3) Glue adjustment: Weigh 50g flour, 1g potassium permanganate, 1g lignin, 0.25g sodium hydroxide, 200g water, add flour into water and stir for 6-8min at a heating temperature of 60-75°C, Then add lignin and stir for 8-10 minutes, then add potassium permanganate and stir for 5-30 minutes, then add sodium hydroxide and continue stirring for 30-40 minutes, and finally add an appropriate amount of defoamer and stir for 2-3 minutes.

[0067] In the comparative example experiment, add potassium permanganate and do not add the stickiness situation of two kinds of glues of potassium permanganate. After comparison, it is found that there is ...

Abstract

The invention provides a method for preparing biomass materials on the basis of cinnamomum longepaniculatum leaf residues. The method includes steps of drying, smashing, adhesive mixing and setting. The method has the advantages that the cinnamomum longepaniculatum leaf residues can be stably adhered by the aid of special technological operation and specially prepared flour adhesive which comprises flour, lignin, sodium hydroxide and water; the shortcoming that materials are loose and are easy to break and smash after being mixed with existing cinnamomum longepaniculatum leaf residues can be overcome by the aid of the method, the strength of the biomass materials can be reinforced, and the biomass materials are natural and harmless.

Description

technical field [0001] The invention relates to the field of biomass materials, in particular to a method for preparing biomass materials based on camphor leaf residue. technical background [0002] Yibin, a prefecture-level city in Sichuan Province, a national historical and cultural city, the starting point of the Southern Silk Road, is one of the cities with the earliest development and the longest history in the upper reaches of the Yangtze River. Yibin has a precious tree species of Lauraceae ~~~ oil camphor (Cinnamomum longipaniculatum (Gamble) N.Chao ex H.W.Li). As a special product in China, there are more than 500,000 mu of camphor oil in Yibin City, and the output of camphor oil accounts for 70% of the output of similar products in the country. The annual output of camphor oil in Yibin area reaches 6,500 tons, and the by-product is 310,000 tons of camphor leaf residue. [0003] According to the data, camphor leaf residue can be used to prepare biomass fuel, grow e...
