The present application belongs to a technical field of modifying natural polymer materials, provides a high-viscosity lithium carboxymethyl cellulose and preparation method therefor and application thereof. Raw materials are fed into a reactor, and the high-viscosity lithium carboxymethyl cellulose is prepared through an alkalization reaction, an etherification reaction, an acidification reaction and a substitution reaction. The prepared high-viscosity lithium carboxymethyl cellulose can be used for preparing a negative electrode plate of a lithium-ion battery. Compared with the existing lithium carboxymethyl cellulose, the high-viscosity lithium carboxymethyl cellulose provided by the present application can not only reduce an application amount in preparing a negative electrode plate of a lithium-ion battery so as to save a using cost, but also promote an electrochemical performance of the material in combination with a sodium lignin sulfonate.

This invention relates to making and using a stabilizer that is effective in small amounts and, particularly useful for stabilizing low solids liquids, e.g., dispersions, emulsions, and suspensions, used in foods, pharmaceuticals, nutraceuticals, and similar industrial applications, which comprises, microcrystalline cellulose, (preferably, colloidal hydrolyzed MCC); a first carboxymethyl cellulose having a viscosity of 30-85 cP at 2% in deionized water; and, a degree of carboxymethyl substitutions of 0.60 to 0.85, and a second carboxymethyl cellulose having a viscosity of 400-800 cP at 2% in deionized water, and a degree of carboxymethyl substitutions of 0.80 to 0.95; and, the stabilizer may be made by preparing a moist MCC “wetcake”; thoroughly mixing the wetcake with a dry blended mixture of low DS and medium DS, CMCs; preferably, in a MCC/low DS CMC/medium DS CMC ratio range of about 88/6/6 to about 92/4/4, adding that mixture to an extruder; preparing a slurry of the extrudate in deionized water; and, optionally, pumping the slurry to a spray dryer to produce a powder.

The present invention provides: a binder for inorganic fibers, the binder being characterized by containing (B) an ammonia-modified maleic anhydride-containing copolymer at a quantity of 3 parts by mass or more relative to 100 parts by mass of (A) a cellulose ether having a viscosity at 20° C. of 500 mPa.Math.s or less when in the form of a 2 mass % aqueous solution: and an inorganic fiber mat comprising inorganic fibers treated with the binder for inorganic fibers. By using this binder for inorganic fibers, it is possible to produce an inorganic fiber mat having a high recoverability similar to that of a phenol resin, and the amount of volatile organic compounds released from the inorganic fiber mat is extremely low.

The present disclosure relates to a preparation method for a super absorbent polymer film. Specifically, it relates to a preparation method for a new type of super absorbent polymer film, which is thin and exhibits excellent absorption performance. In addition, the super absorbent polymer film of the present disclosure has excellent flexibility and excellent mechanical properties, is free from scattering or leaking, and does not require an auxiliary substance such as pulp, so that products can be made thinner and the manufacturing process and costs may be reduced.
