Abstract
The invention relates to the technical field of chemical industry, in particular to an epoxy paint diluter as well as a preparation method and an application thereof. The epoxy paint diluter is prepared by dimethyl carbonate and alcohols. The preparation method comprises the following steps of: mixing the dimethyl carbonate and the alcohols according to the proportion, evenly stirring, filtering and packaging. The epoxy paint diluter has the characteristics of favorable intermiscibility with the epoxy paint, good viscosity break effect, high safety factor, little harm to the environment and the contactors, energy saving and environmental friendliness, can be used for diluting the epoxy paint, and is especially suitable for diluting epoxy insulation baking paint.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to a kind of epoxy lacquer diluent and compound method thereof and application.
Background technology
Epoxy lacquer diluent mainly is made up of aromatic hydrocarbon benzene,toluene,xylene (hereinafter to be referred as triphen), ketone and alcohols etc. at present, and wherein, benzene toxicity can cause leukemia greatly; Toluene is precursor chemicals, national strict control, and flash-point is lower, and combustion explosion is dangerous big; The dimethylbenzene boiling point is higher, stoving temperature height (130-140 ℃), and the time of curing is long, waste energy, and triphen all has bigger harm to environment and contactee.
The paint thinner of existing no benzene mainly is made up of aliphatic hydrocarbon, vinyl acetic monomer, N-BUTYL ACETATE and alcohols etc., but because the aliphatic hydrocarbon flash-point is lower, the baker blast easily takes place when being used for the epoxy insulation baking paint dilution, and the aliphatic hydrocarbon solvency power is relatively poor, viscosity reducing effect is unsatisfactory.
Summary of the invention
The objective of the invention is to take the solvent methylcarbonate of environmental protection to replace existing aromatic hydrocarbon and aliphatic solvents, make a kind of epoxy lacquer diluent of safe and energy-conserving and environment-protective.
Another purpose of the present invention provides the compound method of above-mentioned epoxy lacquer diluent.
Still a further object of the present invention provides the application of above-mentioned epoxy lacquer diluent.
The invention provides following technical scheme:
A kind of epoxy lacquer diluent is characterized in that: be formulated by methylcarbonate and alcohols.
As preferably, be formulated by following materials of weight proportions:
Methylcarbonate 50-90%
Alcohols 10-50%.
Wherein, the weight proportion of methylcarbonate is 60-80% more preferably, and most preferably 70%; The weight proportion of alcohols is 20-40% more preferably, and most preferably 30%.
As preferably, described alcohols is one or more the mixture in methyl alcohol, ethanol, propyl alcohol and the butanols.More preferably, described alcohols is an ethanol.
The present invention also provides the compound method of above-mentioned epoxy lacquer diluent, is that methylcarbonate and the alcohols with described weight proportion mixes, and stirs, filter, packing.
Epoxy lacquer diluent of the present invention is mainly used in the dilution of epoxy-based lacquers, is particularly useful for the dilution of epoxy insulation baking paint.
Ultimate principle of the present invention is as follows:
Methylcarbonate be a kind of nontoxic, environmental-protecting performance is excellent, broad-spectrum industrial chemicals, higher (remaining silent)/17 of its flash-point ℃, low 90.3 ℃ of boiling points, evaporation rate is very fast, can with nearly all immiscible organic solvent; Its viscosity is low, steam forces down, Lower Explosive Limit height in the air, be that collection spatter property and security are green solvent all over the body.
Because the methylcarbonate boiling point is lower and evaporation rate is very fast, the epoxy lacquer diluent of methylcarbonate replacement triphen manufacturing reaches the purpose of energy-saving safe.
Compared to existing technology, the present invention has following technique effect:
Good with the epoxy-based lacquers intermiscibility, viscosity reducing effect is good, and the safety coefficient height endangers for a short time to environment and contactee, and energy-conserving and environment-protective can be used for the dilution of epoxy-based lacquers, are particularly useful for the dilution of epoxy insulation baking paint.
