Technical Field
The invention relates to the technical field of chemical product production, in particular to a plant microfiber sucrose fatty acid ester enrichment and a preparation method thereof.
Background
Plant microfine fiber is a nano-grade biomass material, not only possesses various advantages of nano-fibre, but also possesses many characteristics not possessed by general cellulose, such as high strength, high water-retaining value, high viscosity, high dispersion and high stability, at the same time, because its strength is high, rigidity is large, weight is light, and it can be biodegraded and regenerated, its application prospect in advanced composite material is very extensive.
The preparation process of the plant microfine fibers is usually carried out in a liquid medium, the concentration of the obtained plant microfine fibers in a suspension or gel is low, the fiber content is usually below 1% so as to ensure a highly dispersed state of the fibers in the liquid medium and maintain the nanometer size of the fibers, and the microfine fibers with too low concentration need to be dispersed into other materials to remove more water, so that the operation is inconvenient. The low concentration of plant fines not only affects their use, but also increases transportation and storage costs, and in addition, effective concentration or drying and redispersion of the plant fines product after drying is a further issue to be considered for plant fines storage, transportation and use. Therefore, attempts have been made to prepare microfibrous concentrates.

In comparison with comparative examples, the method for preparing the sucrose fatty acid ester-enriched vegetable microfine fibers of examples 1 to 7, which uses sucrose fatty acid ester as a carrier, can enrich the vegetable microfine fibers in the form of coating or coprecipitation from water and can redisperse them again.
Examples 1-7 used sucrose fatty acid esters with HLB values between 7 and 16. The HLB is lower than 7, the lipophilicity of the sucrose fatty acid ester is enhanced, the water dispersibility is poor, and the sucrose fatty acid ester is not suitable for being used as a carrier to enrich plant micro fibers, so the sucrose fatty acid ester with the HLB value of 7-16 is preferably used as the carrier of the enrichment substance in the technical scheme. The mass ratio of the plant fine fibers to the sucrose fatty acid ester is 1: 0.05-10 in terms of dry matter, the mass ratio of the plant fine fibers to the sucrose fatty acid ester is 1:10 in example 4, the content of the plant fine fibers in the obtained pulp is close to that of the plant fine fiber dispersion liquid before enrichment, and if the content of the plant fine fibers in the pulp exceeds the ratio, the practicability of the plant fine fiber sucrose fatty acid ester enriched pulp is inferior to that of the plant fine fiber dispersion liquid; the mass ratio of the plant microfine fibers to the sucrose fatty acid esters of example 6 was less than 1:0.05, the volume ratio of the upper layer to the lower layer of the liquid is about 1:9 after the pH value is adjusted, the liquid is not obviously layered, and the enrichment of plant microfine fibers is not facilitated, in order to solve the problem, all materials need to be subjected to centrifugal separation, and the technical scheme is not economical enough for preparing the plant microfine fiber sucrose fatty acid ester enrichment in large scale, so that the preferred mass ratio (calculated by dry matters) of the plant microfine fibers to the sucrose fatty acid esters is 1: 0.05-10. The condition for forming the plant microfine fiber sucrose fatty acid ester enrichment is that the pH value of the material is between 1 and 4. In example 7, the pH value is lower than 1, the formed concentrated substance is relatively granular precipitate, and the dispersibility in water and organic solvents is poor, so that the redispersion of plant micro-fibers is not facilitated; in example 5, the pH value is higher than 4, the volume ratio of the upper layer to the lower layer of the liquid is about 1:9 after the pH value is adjusted based on the properties of the sucrose fatty acid ester, a gel is not easy to form, plant microfine fibers are effectively enriched, the economy is poor for preparing the plant microfine sucrose fatty acid ester enrichment substance in large batch, and therefore the pH value of the preferred material of the conditions for forming the plant microfine sucrose fatty acid ester enrichment substance in the technical scheme is between 1 and 4.
The present invention can provide a microfibrous cellulose aggregate which can reduce the transportation cost and storage cost per microfibrous cellulose unit. Further, a method for producing a microfibrous cellulose aggregate which produces the microfibrous cellulose aggregate can be provided. The present invention is not limited to the above embodiment, and various modifications may be made without departing from the spirit of the present invention.
