Description
Technical field
The present invention relates to anticorrosive paint technical field, specifically a kind of resin mill base and production technology thereof.
Background technology
Resin mill base is that to produce coating be one of the raw material used, for producing the resin mill base of water paint, it is desirable to its water solublity
Must get well, otherwise, after coating mixes with water, mill base can float in water, can cause pigment coloration poor effect；Additionally,
In resin mill base production process, it is easy to shrinkage cavity can be produced, produce shrinkage cavity and can cause the decline of product quality, also result in the later stage
When coating uses, paint film is unsmooth；Furthermore, during resin mill base produces, need heating and insulation, so that each raw material
Between reaction can be normally carried out, but heating and insulation during, solvent is readily volatilized, causes raw materials for production
Waste and the pollution of environment, bring loss and inconvenience to manufacturing enterprise.
Summary of the invention
For above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of resin mill base and production technology thereof, to solve
The problems referred to above.
The present invention solves the technical scheme that its technical problem taked and includes: a kind of resin mill base, including 260～330 parts of asphalt mixtures modified by epoxy resin
Fat, 130～160 parts of alcohol ether solvents, 60～80 parts of isooctanol, 35～50 parts of diethanolamine and polyimide resin more than 100～200 parts,
After chemical reaction and mixing, disperse to make in 10～20 parts of deionized waters, and above number is by weight.
The boils up till of isooctanol 185-189 DEG C, compares other solvents, and boiling point is high.Production at resin mill base
Cheng Zhong, reaction temperature is typically at about 100 DEG C.Select isooctanol as solvent, utilize the feature that its boiling point is high, producing
In journey the most volatile, both reduced loss, again safety and environmental protection；Meanwhile, isooctanol also has antiseptical effect, increases coating
Antiseptic effect.
In order to further increase the water solublity of epoxy resin, further technical scheme is: also include 1～3 part of ethylenediamine, should
Number is by weight.
Further technical scheme is: also including 200～300 parts of cross-linking agent, this number is by weight.Each raw material in production process
Disperseing bad to produce shrinkage cavity in water, cross-linking agent can play nonshrink hole effect, it is to avoid produces shrinkage cavity, improves the product of product
Matter.
Further technical scheme is: described alcohol ether solvents is propylene glycol monomethyl ether.Propylene glycol monomethyl ether can strengthen thickness.Do not add
Entering the film thickness of propylene glycol monomethyl ether generally about 10 μm, antiseptic effect is poor；After adding propylene glycol monomethyl ether, paint film thickness
Degree is up to 20-30 μm, and antiseptic property is greatly improved.Additionally, propylene glycol monomethyl ether is low to the toxicity of human body, safer.
Further technical scheme is: described cross-linking agent is made up according to weight proportion of the raw material of following component: more than 280～340 parts
Isocyanates, 140～180 parts of butyl glycol ethers, 200～250 parts of isooctanol, 1～4 part of catalyst and 280～320 parts the third two
Alcohol methyl ether.
Further technical scheme is: described polyisocyanates is TDI, and described catalyst is organic tin liquor.TDI is that toluene two is different
Cyanate, is that a kind of sealer, TDI and diethanolamine coordinate, epoxy resin not open loop can either be avoided to cause it not have water
The problem of dissolubility, again it can be avoided that epoxy resin open loop causes its water solublity too strong too much, so that the problem that solvent loss is the biggest,
Achieve the moderate of epoxy resin open loop, it is ensured that while product quality, reduce the loss of raw material, reduce production cost.
The present invention solves the scheme of its technical problem and also includes: the production technology of a kind of resin mill base, comprises the following steps:
Step 1: 60～80 parts of isooctanol and 130～160 parts of propylene glycol monomethyl ethers are added in the change epoxy still of melting ring epoxy resins,
Then in changing epoxy still, add 260～330 parts of epoxy resin；
Step 2: change the internal intensification of epoxy still, until epoxy resin all melts；
Step 3: the epoxy resin after fusing is put into reactor, heats up and start stirring, add 35～50 parts in reactor
Diethanolamine and 1～3 part of ethylenediamine, reaction is to epoxy resin open loop；
Step 4: add polyimide resin more than 100～200 parts and 200～300 parts of cross-linking agent to reactor, is tamping anti-after charging
Answer the kettle cover of still；
Step 5: be warming up to 110 DEG C ± 2 DEG C, insulation reaction more than 2 hours, be then cooled to less than 100 DEG C, add 10～
20 parts of deionized waters, and insulation reaction 1～1.5 hours at this temperature, preparation completes；
In above-mentioned steps, the number of each raw material is by weight.
Further technical scheme is: in step 3, be warming up to when 80 DEG C add described diethanolamine and described ethylenediamine, insulation
React more than 2 hours.The ring that insulation can make epoxy resin in more than two hours is opened, if temperature retention time is the shortest, then and epoxy resin
Ring do not open, epoxy resin does not have water solublity.
Further technical scheme is: in step 4, after adding described many polyimide resins, be warming up to 100 DEG C ± 2 DEG C, and insulation 2 is little
Described cross-linking agent is added time after.
Further technical scheme is: in production process, the condenser of reactor is passed through cooling water, described epoxy melting after,
The agitating device of described reactor starts stirring and stirs to having prepared.
In step 5, after being warming up to 110 DEG C ± 2 DEG C, temperature retention time must be more than 2 hours, if temperature retention time is held not
It is easily generated shrinkage cavity.
The invention has the beneficial effects as follows:
1, isooctanol boils up till 185-189 DEG C, compares other solvents, and boiling point is high.Production at resin mill base
Cheng Zhong, reaction temperature is typically at about 100 DEG C.Select isooctanol as solvent, utilize the feature that its boiling point is high, producing
In journey the most volatile, both reduced loss, again safety and environmental protection；Meanwhile, isooctanol also has antiseptical effect, increases coating
Antiseptic effect.
2, adding diethanolamine and can increase the water solublity of epoxy resin, product hydrophilic is more preferable, does not haves layering after adding water
Phenomenon, the coloring effect of coating is more preferable, and product quality is finer and smoother.
3, add cross-linking agent and there is the effect in nonshrink hole, it is to avoid shrinkage cavity occurs in product, and paint film is more smooth.
4, cross-linking agent adds TDI as sealer, it is possible to avoid epoxy resin open loop to cause its water solublity too strong too much, thus
Make the problem that solvent loss is the biggest, it is achieved that epoxy resin open loop moderate, it is ensured that while product quality, reduce the loss of raw material,
Reduce production cost.
5, the production technology of the present invention, the order of addition of rational arranging raw material, reaction temperature and response time, production efficiency is high,
Ensure that epoxy resin open loop is moderate, make product water dissolubility moderate, and avoid product to produce shrinkage cavity, improving product in process of production
Quality.
6, the production technology of the present invention, the part of exothermic reaction uses dropping mode to feed, it is to avoid solvent boiling phenomenon occurs, protects
The waste of solvent is avoided in card reaction while being normally carried out.
