Description
Technical field
The present invention relates to a kind of environment-friendly and low-toxicity Polar diluents, belong to diluent technical field.
Background technology
Paint class coating needs to be diluted using diluent when in use, reduces resin viscosity, improves processing performance.One
The stronger lacquer type organic coating of a little polarity needs accordingly to use polarity relatively strong and/or dissolving such as polyurethane paint, nitrate paint, epoxy resin coating
The stronger solvent of property carrys out prepared and diluted agent, such as benzene,toluene,xylene, ethers, acetone, cyclohexanone, esters, but above-mentioned solvent one
As all have larger toxicity, environmental pollution is larger, and especially to human body, there are larger harm.Current social is to environment-protecting and non-poisonous
Diluent there is an urgent need.Dimethyl carbonate is a kind of industrial chemicals less toxic, environmental-protecting performance is excellent, in the prior art
Through using dimethyl carbonate to be used as diluent in research, as patent CN200910193946.3 discloses a kind of epoxy-based lacquers dilution
Agent and its preparation method and application are the diluents as epoxy-based lacquers after mixing dimethyl carbonate with alcohols；Patent
CN201110193871.6 discloses a kind of Benzene-free environment-friendlydiluent diluent, is to be used in mixed way dimethyl carbonate and trichloroethanes, together
A certain amount of butyl acetates of Shi Tianjia；Patent CN201610737889.0 discloses a kind of industrial paint environmental protection exemption diluent, group
At including dimethyl carbonate, tert-butyl acetate, methyl acetate, butyl acetate and Porous deproteinized bone, from the point of view of the patent having disclosed,
Using dimethyl carbonate as diluent in use, being used after being required to coordinate a certain proportion of alcohols or esters, original
Because being since dimethyl carbonate polarity is weaker, when painting class for polarity, solvability is poor, and using effect is bad, but above-mentioned side
In the alcohols and esters that are used in case and trichloroethanes still includes the solvent that some are more toxic, such as methanol, tumer
Ester and trichloroethanes cannot reach low toxic and environment-friendly effect truly, and the diluent in said program is for strong pole
Property paint solvability it is still weaker.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of environment-friendly and low-toxicity Polar diluents, specific technical solution is：
A kind of environment-friendly and low-toxicity Polar diluents, are made of the raw material of following mass ratio：50 ~ 80wt% of dimethyl carbonate, 1,1-
10 ~ 30wt% of dichloroethanes, 5 ~ 20wt% of formal.
Further, the dimethyl carbonate is after being handled by the DMC recombination lease making activated carbon decolorizings of coal alcohol by-product
Obtained dimethyl carbonate alcoholic solution.
Further, the alcohol content in the dimethyl carbonate alcoholic solution is 10 ~ 20wt%.
Further, 1, the 1- dichloroethanes is to be distilled to obtain by the high-boiling components in PVC Production Process.
Further, the application of above-mentioned environment-friendly and low-toxicity Polar diluents, for diluting polyurethanes paint, polyesters oil
Paint, nitro class paint, epoxy resin paint.
The beneficial point of the present invention is：All compositions are less toxic raw material in the diluent of the present invention, wherein with low toxicity, ring
The excellent dimethyl carbonate of guaranteed cost is main constituents, by the way that proper amount of 1,1- dichloroethanes and dimethanol contracting first is added
Aldehyde can be obviously improved its dissolution painted to polarity, solve lacking for dimethyl carbonate class diluent in the prior art
It falls into.And 1, the 1- dichloroethanes and formal being added equally are safety low-poison raw material, are harmful to human health, because
This can be used as a kind of environment-friendly and low-toxicity diluent use.
In addition, the dimethyl carbonate in the present invention and 1,1- dichloroethanes is the by-product of chemical industry, be may be implemented
The comprehensive utilization of resource reduces cost of material, and wherein dimethyl carbonate makes after decolourizing for the DMC heavy constituents of coal alcohol by-product
With containing a certain amount of fusel, facilitation can be played to the dilution effect of the diluent of the present invention.
The diluent of the present invention can be used for substituting traditional acetone, toluene class diluent, have to polar resin paint good
Good dilution effect, and with the low toxicity characteristic not available for traditional dilute agent, safety and environmental protection.
Specific implementation mode
