3results about How to "High nucleation efficiency" patented technology

The invention relates to a preparation method and application of a nucleating agent. The preparation method comprises the following steps: mixing solvent pure water, calcium hydroxide and fatty acid methyl ester sulfonate, and heating; dropwise adding hexahydrophthalic anhydride into the mixed solution, and after dropwise adding is completed, carrying out heat preservation reaction to obtain the calcium hexahydrophthalate. The product has excellent performance when used for thermoplastic resin such as polyolefin.

The application discloses a kind of biobased degradable modified plastics and its preparation method and application, the modified plastics are with polylactic acid and poly (3-hydroxybutyric acid-co-3-hydroxyhexanoate) as matrix, with hyperbranched polyester as compatibilizer, with zinc phytate as nucleating agent, the end hydroxyl group of hyperbranched polyester and the ester group of two polyesters form hydrogen bond, effectively inhibit dispersion phase reunion;Zinc phytate promotes polylactic acid crystallization;The prepared modified plastics have excellent impact toughness and heat resistance, and all raw material components are derived from biomass, and the degradation rate is more than 90% under composting conditions for 180 days, suitable for food packaging and disposable product field.

This invention discloses a self-activated solid waste slurry and its preparation method, comprising waste slag, a solid waste cementitious material, and water. The components are expressed as follows by weight percentage or parts: 100 parts waste slag; 15-60 parts solid waste cementitious material, wherein the solid waste cementitious material consists of a silicon-aluminum rich precursor, a strongly alkaline activation source, and a rheology-modifying supplementary source, with a mass ratio of 1:(0.2-0.8):(0.1-0.4); and water. This invention eliminates the highly corrosive liquid chemical activator required in traditional alkaline activation materials, achieving self-activation through dry powder premixing of a strongly alkaline activation source, a silicon-aluminum rich precursor, and a rheology-modifying supplementary source.
