Description
Technical Field
The invention belongs to the technical field of novel materials of hyperdispersants, and particularly relates to a preparation method and application of a bio-based flame-retardant hyperdispersant.
Background
The hyperdispersant is a novel dispersant assistant developed in recent years, and compared with the traditional dispersant, the hyperdispersant has the structural characteristics that one end of the hyperdispersant is provided with an anchoring group which can be firmly combined with the surface of inorganic powder; the other end has a solvating segment with better compatibility with the dispersion medium. The anchoring groups can be tightly combined on the surface of the powder in a single-point or multi-point mode through the actions of ion pairs, hydrogen bonds, Van der Waals force and the like, so that the hyperdispersant is prevented from being desorbed; the solvating chains are polymer chains capable of being solvated by the medium, and the solvating chains have good compatibility with the dispersion medium and a better stretching idea, so that a protective layer with enough thickness is formed on the surface of the powder.
At present, surface modification becomes one of the most important and necessary deep processing technologies of inorganic powder, mainly takes organic coating as a main component, and the used organic modifiers comprise surfactants such as higher fatty acid containing 16-18 carbon atoms, resin acid and the like, macromolecular dispersants such as polyethylene glycol, polymethyl methacrylate and the like, and coupling agents such as silane, titanate, aluminate and the like. The coupling agent has high cost, complex modification process, pollution of the titanate coupling agent and the like, and cannot be popularized and applied in a large area. The stearic acid dispersant which is most widely used in industry has only one carboxyl anchoring point and longer alkyl, so the modification effect is not ideal. Meanwhile, most of the hyperdispersants produced in the current market have single function, and the application field is limited.
Oleic acid is a typical unsaturated fatty acid, has rich yield, is easy to degrade and regenerate, and has wide practical value in sustainable development. Oleic acid is a monounsaturated Omega-9 fatty acid, is present in the bodies of animals and plants, and is an essential nutrient in animal food. In animal fat, oleic acid accounts for 40% -50% of fatty acid. The content of the plant oil is larger, such as 83 percent of the tea oil, 54 percent of the peanut oil and 55 to 83 percent of the olive oil. Because the double bond in the oleic acid can be converted, a plurality of products with high added values can be obtained, and the utilization rate of resources can be greatly improved. Oleic acid and its derivatives are important chemical intermediates in pharmaceutical and cosmetic industries, and oleic acid is directly amidated to obtain products with excellent solubility, no toxicity, high flash point and low volatility.
The molecular structure of the double-spiro phosphorus melamine salt flame retardant (IFR) mainly comprises a carbon source, an acid source and a gas source, and the double-spiro phosphorus melamine salt flame retardant contains rich polyfunctional group carbon forming agents, and can generate an expanded porous carbon layer and release inert gas when being heated, so that the flame retardant has the advantages of being difficult to combust, preventing flame from diffusing, delaying the fire spreading speed and the like, the phosphorus-nitrogen intumescent flame retardant is simple in synthesis process, generally adopts a one-step or two-step synthesis method, and the obtained product only needs simple purification treatment, thereby greatly reducing the large-scale production cost of enterprises.
The grafting reaction of the oleic acid can be used for preparing the environment-friendly bio-based flame retardant hyper-dispersant, and the carboxyl at one end of the molecular chain of the oleic acid can perform amidation reaction with the amino of the double-spiro phosphorus melamine salt (IFR) to generate the bio-based flame retardant hyper-dispersant (OA-g-IFR). OA-g-IFR is used as a flame-retardant hyper-dispersant with double functions of flame retardance and dispersion, the molecular structure of the OA-g-IFR contains a plurality of anchoring groups, and the OA-g-IFR can form multi-point anchoring on the surface of inorganic powder and firmly attach to the surface of the inorganic powder, thereby greatly improving the dispersibility of the inorganic powder in polymers and simultaneously enabling the composite material to have good flame retardance.
High Density Polyethylene (HDPE) is one of five general-purpose plastics, and is widely applied to industry and daily life, and the mechanical property of the material can be further improved, the use cost is reduced, and the application field is widened by blending and compounding high-filling calcium carbonate powder in HDPE resin. But the calcium carbonate surface contains a large amount of polar hydroxyl groups, and the compatibility of the blending interface of the calcium carbonate and the non-polar HDPE is poor, so that the mechanical property of the material is reduced. Meanwhile, HDPE has a large latent heat of fusion and is sensitive to temperature, and the temperature must be controlled in a narrow range during molding to obtain the optimal mechanical properties. The OA-g-IFR is used for modifying the surface of the calcium carbonate powder, so that the interface compatibility of the calcium carbonate powder and HDPE can be improved, and the tensile strength and the flame retardant property of the composite material can be enhanced.
Li et al report that the invention patent is a phosphorus-free copolymer scale inhibition and dispersion agent (CN 103804562A), which is prepared by polymerizing 5-15% of unsaturated fatty acid with 16-24 carbon atoms and 85-95% of unsaturated carboxylic acid with 3-8 carbon atoms in an organic solvent by an inorganic peroxide initiator in one step; an invention patent of amphiphilic hyper-dispersant and a preparation method thereof (CN 104801234A) reported by foal et al is that oleic acid, maleic anhydride, methyl methacrylate, azobisisobutyronitrile and isopropanol are mixed to obtain a solution A, and the solution A is added into N2Dropwise adding the mixture into an acetone solution under the environment protection and stirring state to obtain an amphiphilic hyper-dispersant; dayu reports a patent of 'white carbon black high-activity dispersant composition and a preparation method thereof' (CN 103524793A), firstly, long-chain fatty acid, octadecanol, diethylene glycol, monoglyceride, hexadecyl trimethyl ammonium chloride and C9 petroleum resin are put into a negative pressure reaction kettle, the temperature is raised, at least one of hydrazide and sulfonyl hydrazide is added into the reaction kettle, and after the reaction is finished, the white carbon black high-activity dispersant composition is prepared.
The research of the hyperdispersant does not relate to the preparation of the bio-based flame-retardant hyperdispersant by using oleic acid as a solvation chain segment of the flame-retardant hyperdispersant and using the bis-spiro phosphorus melamine salt as a flame-retardant segment, and the bio-based flame-retardant hyperdispersant is not reported in documents at present.
