Abstract
Provided is an emulsification polymerization device capable of carrying out circulation emulsification and emulsion polymerization at the same time. The emulsification polymerization device is characterized in that a circulation conduit is drawn from the bottom of a reaction kettle and communicated with a high-pressure pump and a mistorizer inside an upper mouth of the reaction kettle in sequence to form a circulation emulsification system inside and outside the kettle. When the emulsification polymerization device is in operation, the high-pressure pump enables reactants at the bottom to flow back to an upper portion of the reaction kettle through the mistorizer, and enables materials in the kettle to be subjected to better circulation shearing and emulsion dispersion. The circulation emulsification and the emulsion polymerization are conducted simultaneously, so that the emulsion polymerization is stable, emulsion particle size is small, emulsion polymerization effect is good, and the product quality and the production efficiency are improved.
Description
Technical field
The utility model relates to a kind of emulsion polymerization device, and more particularly, the utility model relates to a kind of device that can in circulating emulsion, carry out emulsion polymerization.
Background technology
Pigment printing binding agent generally adopts the method for emulsion polymerization preparation; Because non-environmental-pollution, toxicological harmless, plurality of advantages such as chromatogram is complete, colorant match is easy, lovely luster; And have transparency height, characteristics such as heat-resisting, fast light, ageing-resistant, in printing and dyeing industry, be used widely.
Pigment printing binding agent generally is macromolecular compound emulsion or the solution with certain polymerization degree.It is one of important composition composition of textile printing pigment, in mill base, is solution or dispersed.Film forming adhesion process can take place in them under the effect of higher temperature and catalyzer, after solvent or other liquid evaporation, form very thin film in the place of stamp, coating particles is adhered to the surface of fabric.Pigment printing binding agent commonly used is the oil/water emulsion of high molecular polymer mostly, is polymer beads mutually in promptly, and the foreign minister is a water, and polymer beads is dispersed among the water.The quality of pigment printing final product quality directly receives the printing adhesive Effect on Performance.Therefore, obtaining stable dispersion system is the key that makes the better printing adhesive of over-all properties.
Except factors such as monomeric species and proportioning, linking agent kind and consumption, emulsifying agent consumption and proportioning, initiator amount, temperature to the tackiness agent Effect on Performance, production unit also has considerable influence to the stability of letex polymerization.
Because existing emulsion polymerization still lacks enough shear agitation effects, for obtaining stable emulsion dispersion system, often adopts the special-purpose emulsifying device that partial monosomy is carried out preparatory emulsification.However, when the emulsifying agent of selecting for use and protective colloid are not enough or not ideal enough, often cause that letex polymerization is unstable, emulsion dispersion is inhomogeneous.
Summary of the invention:
The purpose of the utility model is to overcome the deficiency of prior art equipment, and a kind of emulsion polymerization device is provided, and circulating emulsion and letex polymerization are carried out simultaneously, make letex polymerization more steadily, the emulsification dispersion effect is better.
The purpose of the utility model realizes through following technical scheme: a kind of novel emulsion polymerization device is provided, comprises reaction kettle, circulating emulsion system: said reaction kettle adopts impregnating material (stainless steel of acid-and base-resisting, enamel etc.) to prepare; Said circulating emulsion system is made up of conduit, pump and spraying gun.Conduit is drawn by the bottom of reaction kettle, is connected with spraying gun in reaction kettle is suitable for reading through HPP, constitutes the inside and outside circulating emulsion system of still.
The beneficial effect of the utility model is: the emulsion polymerization device that provides can make circulating emulsion and letex polymerization carry out simultaneously; That is limit circulating emulsion limit letex polymerization; Let letex polymerization more steadily, the letex polymerization better effects if; Obtain littler, the more stable dispersion system of particle diameter, the performance of printing adhesive is guaranteed.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Among the figure: conduit 1, HPP 2, spraying gun 3.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Referring to accompanying drawing, the utility model comprises: reaction kettle and circulating emulsion system.Said reaction kettle adopts impregnating material (stainless steel of acid-and base-resisting, the enamel etc.) metric system to be equipped with; Said circulating emulsion system is made up of conduit 1, HPP 2, spraying gun 3.Conduit 1 is drawn from the bottom of reaction kettle, connects with the inlet of HPP 2, and the outlet of HPP 2 connects with reaction kettle interior spraying gun 3 suitable for reading, constitutes the inside and outside circulating emulsion system of still.During work; Stirring rake begins to rotate; HPP 2 on the conduit 1 lets the reactant of still bottom be back to the reaction kettle internal upper part through spraying gun 3, makes the interior material of still receive better circulation shear emulsification dissemination, and letex polymerization is more steady, stirring is more abundant, it is more even to mix.The utility model can make circulating emulsion and letex polymerization carry out simultaneously, and the letex polymerization better effects if improves product quality and production efficiency.
Claims (2)
1. an emulsion polymerization device is made up of reaction kettle body, whisking appliance and emulsifier unit, it is characterized in that: emulsifier unit is a circulating emulsion system that is made up of circulation duct, HPP, spraying gun.
2. a kind of emulsion polymerization device according to claim 1 is characterized in that: circulation duct is drawn by the reaction kettle bottom, is communicated with the import of HPP, and the high pressure pump outlet is communicated with reaction kettle interior spraying gun suitable for reading in proper order.
