Abstract
The invention discloses a production method of a modified urea anti-settling agent. The modified urea anti-settling agent belongs to the field of chemical engineering. The production method comprises an N-methylpyrrolidone solution of modified urea, isopropyl myristate, zine stearate and succinate blocked copolymer and complex as raw materials are heated and mixed into the modified urea anti-settling agent. The production method has the advantages of simple processes and good product quality. The product anti-settling principle comprises that because of selective incompatibility of modified urea and a coating system, fine acicular crystals are produced and form a three-dimensional net structure by intercrystalline bonding force so that good system thixotropy is obtained and excellent anti-settling and anti-sagging performances are obtained. In coating storage, the modified urea can effectively prevent pigment and filler settlement and improve viscosity.
Description
Technical field
Product of the present invention belongs to chemical field, relates in particular to a kind of anti-settling agent that modified urea is main material production of take.
Background technology
Anti-settling agent is the rheology control agent of a class coating, it makes coating or paint have anti-settling property, viscosity improves greatly, anti-settling agent plays an important role in modern coatings or paint, the production of coating or paint, storage, application and film performance are produced to material impact, thereby its use comes into one's own day by day.Modified urea anti-settling agent be take modified urea as main raw material, the full name of modified urea is the N-Methyl pyrrolidone solution of modification polyureas, this solution is a kind of solvent-borne type and no-solvent type coating auxiliary rheological agents of being applicable to, this auxiliary agent is by playing a role with the dilution of solvent or liquid resin, modified urea is by incompatible selectively with coating system, under suitable stirring velocity, produce tiny, needle crystal, by the linkage force between crystallization, form tridimensional network, thereby for system provides stronger thixotropy, also just provide superior anti-settling, sag prevention performance.When coating is stored, modified urea utilizes tridimensional network that each pigment component is held, and effectively prevents the sedimentation of face, filler, and viscosity rises simultaneously.And when construction, owing to giving the certain shearing force of system, the reticulated structure of modified urea is destroyed, viscosity declines rapidly, reach construction requirement, after shearing force disappears, this reticulated structure just can be set up in several seconds, thereby prevented the sagging of paint film, this auxiliary rheological agents water white transparency, can not increase color to system, and rear interpolation can produce best effect, sag prevention is good, and consumption is few.It is main raw material that the N-Methyl pyrrolidone solution of modification polyureas is take in the present invention, take Isopropyl myristate, Zinic stearas, amber ester block copolymer and title complex is auxiliary material, by heating, the method for blending takes production modified urea anti-settling agent, the advantage of this production method is: technique is simple, good product quality, product has superior anti-settling, sag prevention performance, when coating is stored, modified urea can effectively prevent the sedimentation of face, filler, and viscosity rises simultaneously.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of method of producing modified urea anti-settling agent in batches, it is main raw material that this anti-settling agent be take the N-Methyl pyrrolidone solution of modification polyureas, take Isopropyl myristate, Zinic stearas, amber ester block copolymer and title complex is auxiliary material, by heating, the method for blending takes production modified urea anti-settling agent, producing the raw material that this product uses has: N-Methyl pyrrolidone solution 18-20%, Isopropyl myristate 74-76%, Zinic stearas 3%, amber ester block copolymer and the title complex 3% of modification polyureas.
The present invention can be achieved through the following technical solutions:
A production method for modified urea anti-settling agent, its feature consists of following steps:
(1) Isopropyl myristate of formula ratio is sent into chemical reaction kettle, warming while stirring, to 40-45 ℃, adds chemical reaction kettle by the N-Methyl pyrrolidone solution of the modification polyureas of formula ratio, stirring reaction 1.1-1.3 hour.
(2) be cooled to normal temperature, continue stir, successively the Zinic stearas of formula ratio and amber ester block copolymer and title complex are added to chemical reaction kettle while stirring, after stirring reaction 0.8-1.0 hour, stop stirring, obtain finished product.
The described temperature of reaction of step (1) is 42.5 ℃; The described normal temperature of step (2) is 5-30 ℃.
The invention has the beneficial effects as follows: the production method that a kind of modified urea anti-settling agent is provided, the method technique is simple, good product quality, product is used mainly as the anti-settling agent of coating or paint, there is superior anti-settling, sag prevention performance, when coating is stored, modified urea can effectively prevent the sedimentation of face, filler, and viscosity rises simultaneously.
