The application relates to the technical field of surfactants, in particular to a low-foaming composite surfactant and application thereof in metal cutting, characterized in that the low-foaming composite surfactant is composed of 55-65% of nonionic surfactant, 4-12% of anionic surfactant, 10-20% of co-surfactant, 3-12% of functional additive and the balance of deionized water; the nonionic surfactant at least contains fatty alcohol polyoxyethylene ether and isomeric tridecanol polyoxyethylene ether; the anionic surfactant is selected from one or more of sodium alkyl benzene sulfonate, sodium fatty alcohol ether sulfate and alpha-olefin sulfonate; the co-surfactant at least contains alkyl glycoside; and the functional additive contains defoaming agent and antirust agent. The foam elimination efficiency is greatly improved through optimization of the nonionic surfactant combination and adoption of a special defoaming agent compounding scheme, and the generation and accumulation of foam in the cutting process are effectively inhibited.

This invention relates to the field of epoxy resins, and discloses an epoxy resin composition, epoxy resin material, its preparation method, and its application. The composition comprises 40-60 parts by weight of glycidyl amine epoxy resin, 10-20 parts by weight of polyenol acetal, 15-45 parts by weight of phenolic epoxy resin, 10-40 parts by weight of phosphorus-containing flame retardant, 1-5 parts by weight of carbon nanotubes, 1-10 parts by weight of curing agent, and 1-10 parts by weight of curing accelerator; the curing agent is a latent curing agent. The epoxy resin composition and epoxy resin material provided by this invention have excellent flame retardant properties, as well as good mechanical and thermal properties.

The invention belongs to the technical field of agricultural chemistry, and discloses a synergistic amino acid-containing water-soluble fertilizer produced from an acidolysis feather liquid and a preparation method thereof. The fertilizer comprises 30%-50% of acidolysis feather liquid, 2%-8% of a zinc-loaded pH-responsive nano-porous silicon carrier, 1%-5% of a boron-loaded pH-responsive nano-porous silicon carrier and nitrogen, phosphorus and potassium nutrient components, wherein the nano-carrier directionally releases zinc and boron in a rhizosphere subacid environment (pH 5.0-6.5), and keeps stable in neutral-alkaline soil. The invention effectively solves the technical contradiction that the stability and the availability of the traditional chelated fertilizer cannot be obtained at the same time, improves the nutrient utilization efficiency, realizes synergistic interaction of amino acids and trace elements, realizes high-value utilization of agricultural wastes, does not need high-temperature and high-pressure or complex equipment, has good compatibility of the components, is clear and transparent, has no precipitate and no flocculation, and is suitable for industrial production. The system is suitable for various water and fertilizer integrated systems such as drip irrigation and sprinkling irrigation.

The invention relates to a coal mine bio-based steel wire rope core flame-retardant conveyor belt and a manufacturing method thereof, and belongs to the technical field of conveyor belts, a core matrix adopts a blending system of bio-based polyamide elastomer and bio-based chlorosulfonated polyethylene, is derived from renewable resources, significantly reduces the carbon footprint of a product, and adopts a halogen-free flame-retardant system, so that the production cost is reduced. The environment and health risks of a halogen flame retardant are avoided, the high hydrogen bond density of the bio-based polyamide elastomer and the high polarity of the bio-based chlorosulfonated polyethylene form a synergy, and a special bonding formula of the m-methylene white system and the cobalt salt bonding accelerant is matched, so that the initial bonding strength and the bonding strength after thermal aging of the steel wire rope are enhanced, and the service life of the steel wire rope is prolonged. The problems that a steel wire rope is easily pulled out and layered in the later period of a traditional conveying belt are solved, the mechanical properties such as tensile strength and elongation at break of the covering rubber layer are superior to those of standard requirements, and heavy load impact and repeated flexing under the working conditions of long distance, large transportation volume and high speed of a coal mine can be borne.
