Abstract
The invention discloses a castor oil derivative anti-settling agent production method which belongs to the field of chemical engineering; a castor oil derivative anti-settling agent is prepared from castor oil derivatives, acrylamide, fatty oil, zinc stearate and ferrous sulfate by plastication, modification and dissolution. The castor oil derivative anti-settling agent production method has the advantages of simple production process and good product quality, the product is mainly used as a coating anti-settling agent, the use method is as follows: the anti-settling agent is added in a coating or a finished product, the weight of the anti-settling agent is 1% of the total weight of the coating, during addition, a grinding machine is used for dispersion, the dispersion time is about 30 minutes, the anti-settling agent added into the coasting can significantly improve the coating performance, makes the a coating layer good in levelling property and free of sagging phenomenon, and prolongs the settling time of a pigment.
Description
Technical field
Product of the present invention belongs to chemical field, relates in particular to a kind of anti-settling agent with castor oil derivative preparation.
Background technology
Anti-settling agent is the rheology control agent of a class coating, it makes coating have anti-settling property, and viscosity improves greatly, and anti-settling agent plays an important role in modern coatings, production, storage, application and film performance to coating produce material impact, thereby its use comes into one's own day by day.Castor oil derivative anti-settling agent is taking castor oil derivative as major ingredient, castor oil derivative is dissolved in non-polar solvent, by disperseing, activating, mutually be wound thixotroping structure by swelling long-chain and play thickening power, in the time being subject to shearing force, winding is opened, structure deteriorate, viscosity can decline, and when shearing force disappears, is wound around again.Castor oil derivative is widely used in giving in various coating its thixotroping structure, can improve the suspension of pigment, control sagging and do not sacrifice mobile and levelling property, control the perviousness to porous body, conventionally not with coating in other compositions react, in organic system, do not affect its water resisting property, coating durability is had no adverse effects, not yellowing in film, and there is good anti-settling property, thickening property, thixotropy, suspension stability, oilness, film-forming properties, chemical stability, in coatings industry, be widely used, its advantage is: easily disperse, can effectively prevent the sagging of thick dope layer in vertical surface, can improve construction and the flowing property of coating, greatly reduce the precipitation of pigment.The present invention is a kind of anti-settling agent with castor oil derivative preparation, the raw material of producing this agent use has: castor oil derivative, acrylamide, fatty oil, Zinic stearas, ferrous sulfate, to plasticate, modification, the method of dissolving is produced this product, this preparation method's advantage is: production technique is simple, good product quality, product uses mainly as the anti-settling agent of coating, using method is, pressing 1% of coating gross weight adds, be added in coating finished product, when interpolation, use shredder to disperse, jitter time is about 30 minutes, this agent is added to and is applied to the performance that can significantly improve coating in coating, make coating leveling good, no sag phenomenon, and extend settling time of pigment.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of method of producing castor oil derivative anti-settling agent in batches, this anti-settling agent is taking castor oil derivative as main raw material, be equipped with again acrylamide, fatty oil, Zinic stearas, ferrous sulfate and produce castor oil derivative anti-settling agent, this anti-settling agent adds the performance that can significantly improve coating in coating to, make coating leveling good, no sag phenomenon, and extended settling time of pigment.The raw material of producing this product use has: castor oil derivative 22-24%, acrylamide 3%, fatty oil 77-79%, Zinic stearas 3%, ferrous sulfate 3%.
The present invention can be achieved through the following technical solutions:
A production method for castor oil derivative anti-settling agent, its feature is made up of following steps:
(1) castor oil derivative of formula ratio being sent into plasticator plasticates, intensification is plasticated, time is 10-12 minute, then the acrylamide of formula ratio is sent into stop plasticating after plasticating 6 minutes after plasticator and castor oil derivative mix is cooled to normal temperature, obtains the castor oil derivative of modification.
(2) fatty oil of formula ratio is sent into chemical reaction kettle, under normal temperature, while stirring the castor oil derivative of modification is added to chemical reaction kettle, be stirred to after whole mixing, add successively Zinic stearas, the ferrous sulfate of formula ratio, continue stirring and after 15 minutes, stop stirring obtaining finished product.
The described plasticating temperature of step (1) is 65-70 DEG C; The described normal temperature of step (2) is 5-30 DEG C.
The invention has the beneficial effects as follows: the production method that a kind of castor oil derivative anti-settling agent is provided, the method technique is simple, good product quality, product uses mainly as the anti-settling agent of coating, the performance that can significantly improve coating in coating is added in this agent to, make coating leveling good, no sag phenomenon, and extended settling time of pigment.
