The invention discloses an aluminum ion battery positive pole piece, an aluminum ion battery and a preparation method, and belongs to the field of batteries. The positive pole piece of the aluminum ion battery comprises an active substance and a binder, the binder is a mixture of 3, 4-ethylenedioxythiophene: polystyrene sulfonate and a functional agent; the active substance is one of graphite, polytriphenylamine, polydiphenylamine, polythiophene, polypyrrole, polyaniline and graphene; the functional agent is one of tannic acid, polyethylene oxide, sorbitol, polyethyleneimine, glycerol and xylitol. Anions of polystyrolsulfon acid and positive ions of 3, 4-ethylenedioxythiophene molecules form positive and negative electron pairs, so that the adhesive has conductivity; the binder enables the active substances to be mutually connected to form conductive chains through intermolecular acting force, and the conductive chains are mutually contacted to form a conductive network. The positive pole piece adopting the binder has good conductivity, temperature resistance and cohesiveness, and does not react with electrolyte, so that the performance of the aluminum ion battery is improved.

The invention relates to the field of D21H21 / 30, and in particular to a stable acid-resistant brightener and a preparation process thereof. The preparation raw materials at least include cyanuric chloride, a sulfonic acid compound, an amine compound and an amino acid. Glycine and glutamic acid are added by design to carry out a condensation reaction, and a liquid fluorescent brightener containing an asymmetric structure is obtained after the reaction, thereby greatly improving the storage stability of the liquid fluorescent brightener. Meanwhile, the liquid fluorescent brightener with a symmetrical structure and the liquid fluorescent brightener with an asymmetric structure generated after the reaction have a composite whitening effect, and the optical behaviors generated by the liquid fluorescent brighteners of different components do not interfere with each other, thereby greatly improving the whitening effect of the stable acid-resistant brightener, solving the problem that the surface of the obtained paper is dark and the whiteness is not high in the process of applying the fluorescent brightener to papermaking, and ensuring the whiteness, water solubility and anti-cation interference ability of the product.

The application discloses a guar gum composition for oil field exploitation and a preparation method thereof, and relates to the technical field of guar gum. The method comprises the following steps: alkalizing, cation etherizing and copolymerizing AM-AMPS with natural guar gum to obtain an organic modified guar gum; introducing active groups through a silane coupling agent KH-560; and finally, carrying out in-situ sol-gel reaction with SiO2-TiO2 composite precursors to form an organic-inorganic interpenetrating network structure. The guar gum composition has good structural stability and viscosity retention capacity at high temperatures, and is suitable for fracturing construction of deep high-temperature oil and gas reservoirs.

The invention discloses a cross-linked netted water-soluble polymer paper reinforcing agent and a preparation method thereof, and belongs to the field of paper reinforcing, at 60-120 DEG C, a catalyst and an amino-containing cross-linking agent are added into a mixed solution dissolved with polyvinyl alcohol and sodium carboxymethyl cellulose while stirring, the catalyst is zinc chloride or aluminum chloride, and then heat preservation treatment is performed; and cooling the obtained reaction system, adding a silane coupling agent, then preserving heat for 0.5-2 hours, and adjusting the pH value of the obtained reaction system to be neutral to obtain the cross-linked network water-soluble polymer paper reinforcing agent, which has wide application prospects in the production of various types of paper (such as packaging paper, writing paper, printing paper and the like).

The invention discloses an anti-corrosion titanium nano-scale coating, and relates to the technical field of anti-corrosion titanium nano-scale coatings. Comprising the following components in parts by weight: 20 to 35 parts of waterborne polyester resin, 10 to 15 parts of epoxy resin, 12 to 18 parts of modified filler, 20 to 50 parts of titanium nano-scale, 3 to 8 parts of organic bentonite, 3 to 12 parts of gamma-aminopropyltriethoxysilane, 1 to 5 parts of nano titanium, 5 to 10 parts of nano titanium dioxide, 5 to 15 parts of fluorocarbon emulsion, 8 to 20 parts of curing agent and 10 to 50 parts of solvent. According to the preparation method, the raw materials are mixed, ground, mixed and finally directly mixed, and the various procedures are synthesized on one device, so that the production efficiency of the anti-corrosion titanium nano-scale coating is improved, and the situation that time is wasted due to the fact that transfer needs to be carried out among the various procedures at present is avoided.
