The application relates to the field of admixtures for concrete, and specifically discloses a preparation method of an anti-segregation agent for concrete and a product thereof. Its preparation method is: dissolving acrylamide in acrylic acid aqueous solution, heating and copolymerizing, adjusting the pH value to weak alkalinity, and then introducing aromatic hydrocarbon sulfonate for reaction to finally obtain the anti-segregation agent of the application. The anti-segregation agent of the present application has good hydrophilicity and certain thickening performance, which can enhance the cohesion between the components in the concrete and reduce the bleeding rate of the concrete. Furthermore, due to the electric repulsion and The combined effect of steric hindrance enables the prepared anti-segregation agent to be fully dispersed in concrete, giving full play to the effect of the anti-segregation agent of this application, and adding the anti-segregation agent to concrete to enhance the cohesion between concrete mixtures properties, reduce the bleeding rate, and improve the segregation resistance of cement; in addition, the preparation method of the present application has a simple production process and is easy for industrial production.

The invention discloses a natural plant stabilizer for beverage products as well as a formulation method and application of the natural plant stabilizer. The stabilizer is prepared by mixing the following components: 1 L of concentrated semen coicis milk, 70-90 g of okra colloid polysaccaride and 50-70 g of Chinese yam colloid polysaccaride; or 2 L of concentrated semen coicis milk, 2 L of concentrated buckwheat saccharificaiton liquid, 1 L of concentrated maize juice (or aloe juice, cactus juice), 800-1200 g of okra colloid polysaccaride and 600-850 g of Chinese yam colloid polysaccaride. One or more of water and cooked nut and coarse cereal powder, or cooked medical materials of homology of medicine and food, or preprocessed fruits and vegetables are added according to a certain percentage as needed to prepare a beverage product. In the invention, natural plant materials are utilized to develop a series of purely natural plant stabilizers, and with the adoption of the stabilizer, the technical problems of layering, flocculation and precipitation in the beverage products are solved. In addition, the prepared stabilizer is rich in a plurality of vitamins, amino acids, polysaccarides and beneficial microelements, has the efficacy of nutrition and health care, and is a natural, safe, nutritious and healthy stablization additive for the beverage products. Furthermore, the natural plant stabilizer can be directly formulated into natural plant beverage products with unique color and flavor.

The invention discloses a preparation method of a polymer shale inhibitor for a drilling fluid. The polymer shale inhibitor is prepared from acrylamide, acrylic acid, potassium hydroxide and dimethyldiallylammonium chloride through an inverse emulsion polymerization technology, and optimum synthesis conditions are as follows: a weight part ratio of the acrylamide monomer to the acrylic acid monomer to the dimethyldiallylammonium chloride monomer is (70-80):(70-80):(15-75), the three monomers are processed to prepare an aqueous phase with the pH value being 10, 10 parts by weight of emulsifiers Sp-80 and T-60 are added to emulsify and disperse the aqueous phase in 100 parts by weight of white oil, and 1-3 parts of a stabilizer N,N'-dilauroyl ethylenediamine diethanesulfonate, the reaction temperature is 30-40 DEG C, the reaction time is 8 h, an oxidation / reduction initiator ratio of n(potassium persulfate):n(sodium hydrogen sulfite) is 1:1, and the weight part number of the initiator is 4. The product can be adsorbed on the surface of clay to form a semi-permeable membrane, has a strong coating effect, can effectively encase rock debris to weaken the hydration and dispersion effect, can compress a double electrode layer to prevent the hydration swelling of the clay, and has a prominent inhibition effect.

The invention discloses a suspension stabilizer for concrete waste slurry concentrate and a preparation method thereof, and belongs to the technical field of concrete waste slurry concentration. %, water-soluble carbohydrates 5-15%, cellulose ether derivatives 1-3%, glycerol 60-75%, phosphate esterification reagent 15-25%, deionized water 2-5% and catalyst 0.5-3% %. The present invention uses expansive clay, water-soluble sugars, cellulose ether derivatives, glycerol and phosphoric acid esterification reagents as main raw materials, and under the action of a catalyst, the concrete waste slurry is prepared through the esterification reaction of hydroxyl groups and phosphoric acid groups Concentrate suspension stabilizer; through the synergistic effect of each component, the stability and homogeneity of concrete waste slurry concentrate during storage and application are significantly improved, and the phenomenon of exudate stratification and compaction is reduced.

The invention discloses a lead-acid storage battery positive lead paste. The lead-acid storage battery positive lead paste is prepared from the following raw materials in parts by weight: 70-90 partsof lead powder, 3-15 parts of sulfuric acid, 5-20 parts of water, 0.05-1 part of short fiber, 0.05-0.5 part of graphite and 0.05-0.5 part of xanthan gum. A lead-acid storage battery prepared by usingthe positive lead paste is high in initial capacity, slow in attenuation and long in cycle life, has strong large current discharge and low temperature charge and discharge performance, and ensures that the combination performance of the lead paste and a grid is significantly improved; and the problems of low initial capacity, short cycle life, easy falling off of active materials and the like inexisting lead-acid storage batteries can be effectively solved.
