Problems solved by technology

Although some existing paint driers can replace traditional lead, manganese, zinc, calcium and other driers, they can only partially (50%) replace cobalt driers, and due to the resource situation in our country, most of them are now Cobalt is dependent on imports and is expensive, so completely replacing cobalt drier has always been an urgent des

Embodiment Construction

[0013] The production method of the paint composite drier involved in the present invention is to carry out compound reaction with light rare earth carbonate——lanthanum carbonate or cerium carbonate (both can be added simultaneously), manganese carbonate, vanadium pentoxide and isooctanoic acid, and its process The process is shown in Figure 1.

[0014] The specific implementation steps are:

[0015] First, vanadium pentoxide and isooctanoic acid are added to the reaction kettle for reaction, the ratio of the two is about 1:4 to 1:5 (the ratio here is the ratio of vanadium ions to isooctanoate ions, that is, 1 vanadium ion Corresponding to 4 to 5 isooctanoic acid ions). The reaction temperature is between 100°C and 250°C (the optimum temperature is 220°C and 230°C), and it is stirred, and the reaction time is about 2 hours.

[0016] Then continue to add manganese carbonate in the reactor, add light rare earth carbonate (lanthanum carbonate or cerium carbonate), and add isooc...

Abstract

The invention discloses a production method of a composite dryer for paint. The production method comprises that a mixture of a light rare earth carbonate, manganese carbonate, vanadium pentoxide and isocaprylic acid undergo a composite reaction to produce the composite dryer for paint. The invention also provides the composite dryer for paint. The composite dryer for paint comprises active components of 1.5 to 2wt% of vanadium ions, 1.5 to 2.5wt% of manganese ions and 4 to 4.5wt% of cerium or lanthanum ions, wherein the total valence-alterable metal ion content is in a range of 7 to 9wt%. The composite dryer for paint can fully replace cobalt as a dryer, can eliminate the pollutants of cobalt and lead, and is nontoxic and environmentally friendly. The composite dryer for paint has integrated effects of a plurality of the existing driers. The production method saves a cost, simplifies a paint blending test, and is convenient for production. The composite dryer for paint has a low use amount and a low cost.

Description

technical field [0001] The invention relates to a coating composite drier and a production method thereof, belonging to the field of fine chemicals. Background technique [0002] Drier is one of the indispensable additives for coatings. Although some existing paint driers can replace traditional lead, manganese, zinc, calcium and other driers, they can only partially (50%) replace cobalt driers, and due to the resource situation in our country, most of them are now Cobalt relies on imports and is expensive, so completely replacing cobalt driers has always been an urgent desire of the coatings industry. [0003] Traditional cobalt, lead, manganese, zinc, calcium and other driers need to be blended in different proportions when used. The procedure is complicated and the amount of addition is large. Paint manufacturers urgently need a drier that can be used alone and with a small amount. Reduce the cost of manpower and material resources. [0004] In addition, cobalt and lea...
