Description
Technical field
The invention belongs to aerosol paint field, particularly to a kind of water alcohol acid aerosol finish paint and system thereof
Preparation Method.
Technical background
Aerosol paint is easy to use because of it, be widely used in paint film repairing, mould, industrial machinery,
Toy, artware, musical instrument, building, steel construction, advertising publicity industry, identify, scribble etc.
Industry-by-industry.The annual production of domestic aerosol paint product, more than 200,000,000 tanks, accounts for aerosol products ratio about
It is 10%.Aerosol paint be by by the successively fill of coating and propellant at slush moulding or aluminum products or
The inert pressure vessel such as tinplate prepares.
Some industrial coatings can carry out machine and spray paint, and then toast, due to permissible with streamline
Avoid artificial directly operation, it is possible to reduce the injury to workman during paint application.With machine
Unlike device streamline application mode, the use process of aerosol paint must pressing nozzle manually
Gai Caineng carries out application, and workman must be at painting site.The rate of volatilization of aerosol paint, ignition point,
The indexs such as explosion limit, VOC content, toxicity are even more important for safety in production.The most domestic
Aerosol paint product composition is all the mixture of oil paint and propellant, does not still have water paint and propellant
The aerosol paint being mixed with.Oil paint in oiliness aerosol paint, VOC content between
It is poisonous and easy to human body that 400g/L～600g/L, VOC contain aromatic hydrocarbons, esters, alcohol ester, alcohols etc.
Fire explosive.CaiHong Precise Chemical Engineering Co., Ltd., Shenzhen City, as the well-known enterprise of aerosol paint product
Industry, aerosol paint product is the mixture of oil paint and propellant.The said firm have developed alcohol-soluble
Esters of acrylic acid aerosol paint, with mixed alcohol as the solvent of coating, substitute tradition to liver, kidney,
Alkane that nervous system is harmful, benzene class, esters, ketones solvent.Although mixed alcohol is relative to tradition
The toxicity of paint solvent is lower, but skin and the nervous system of human body are also harmful to by alcohols, and easily
Fire explosive.
The propellant major part of coating uses liquid gas, and propellant has gas-liquid in aerosol paint can
Biphase, pressure is the spraying power resources of aerosol paint between the gas phase of 0.5～0.8MPa.Throwing of today
Penetrate agent principal item and have the dimethyl ether of nonpolar propane, butane and polarity, the diformazan of hydrophilic and oleophilic
Ether is widely applied.If coating can not uniformly mix with the poor compatibility of propellant, even throw
Penetrating agent can promote coating flocculation to reunite, and variation even can not be sprayed by the atomizing effect of the aerosol paint obtained
Go out.The dimethyl ether of liquid, propane, normal butane, iso-butane are prone to uniformly mix with paint, but
Alkane is not good enough with the compatibility of water alcohol acid finish paint.
Waterborne aerosol paint does not has the product of ripe application, and main difficult technical has: (1) water
Vaporization enthalpy is high, and after the spraying of common water borne aerosol paint, surface drying time is longer than oiliness aerosol paint, discontented
The feature that foot aerosol paint is quick-drying.(2) dimethyl ether in propellant is when 0～35 DEG C, in water
Dissolubility is 30%～40%, but liquid dimethyl ether can cause aqueous emulsion type dispersion coating to flocculate.
(3) water paint ratio paints easy foaming, adds propellant and is ejected into atmospheric environment in tank
Moment can gasify rapidly foaming, so the paint film that waterborne aerosol paint spraying obtains easily bubbles.(4)
Under existing Canning Technique, the fill of aerosol paint institute is all one-component coating, and aqueous one-component
The combination property of coating is general, and the energy force rate one-component oil paint of water-alkali resistance is poor, aqueous one-component
The application of aerosol paint is limited.
Water paint, according to resin discrete particles magnitude classification in water, can be divided into aqueous emulsion type
Dispersion coating and water dilution type dispersion coating.Emulsion particle seed in emulsion type dispersion coating
Footpath 300nm～1 micron, big than water dilution type dispersion coating.In emulsion type dispersion coating
Latex particle in the mean molecule quantity of film forming matter 10000～100000, divide than water dilution type
Prose style free from parallelism coating big.The acid number of the film forming matter in latex particle in emulsion type dispersion coating exists
10～30mgKOH/g, little than water dilution type dispersion coating, hydrophilic disperses than water dilution type
Body coating little.Emulsion type dispersion can be divided into emulsion type alkyd dispersion, emulsified acrylic acid
Dispersion, aq. polyurethane dispersion, emulsion type epoxy-ester dispersion, emulsion type polyvinylidene fluoride
Alkene dispersion.Emulsion type dispersion is in the environment of a large amount of propellant, and propellant is not enough so that dividing greatly
The polymer molecular chain of son amount is fully opened and is dispersed in liquid carrier, but propellant can penetrate into
Enter latex particle and reduce the glass transition temperature of latex particle so that particle condenses mutually.By
Polymer molecular weight in the latex particle of emulsion type dispersion is higher and hydrophilic is little, can cause
Conglomeration macroscopically.The film forming matter of water dilution type alkyd dispersion and the film forming of emulsion type dispersion
Material deployment conditions on liquid carrier is different.Polymer in water dilution type alkyd dispersion becomes
-the COOH of film thing generates, after neutralizing with alkali, the-COO that hydrophilic is strong-, make the polymer of Coiling-type
Strand can stretch to be opened and is dispersed in liquid carrier, and the particle diameter of dispersion is less than 200nm,
Dispersion particle diameters after polymer fully neutralizes is less than 50nm.Alkane in propellant does not affect water
The deployment conditions of the polymer in dilution type alkyd dispersion, the dimethyl ether in propellant is water dilution
The cosolvent of the polymer in type alkyd dispersion.
The water dilution type dispersion of coatings industry application is divided into water dilution type alkyd dispersion, water dilute
Release type acrylic acid dispersion, water dilution type polyester dispersions, water dilution type epoxy-ester dispersion.Water
Dilution type acrylic acid dispersion, water dilution type polyester dispersions can not individually be prepared as film forming matter
One-component self-drying paint, it is necessary to can mix by reactive component with other, makes one-component baking vanish or double
Component air-dry paint.Water dilution type epoxy-ester dispersion has excellent adhesive force, is suitable for the single group of preparation
Part anti-corrosion of metal priming paint.But water dilution type epoxy-ester dispersion itself has deeper yellowish-brown, no
Suitably do finish paint.Water dilution type alkyd dispersion close to colourless, the smooth and fresh print of the coating of preparation
Excellent.
Summary of the invention
In view of this, the present invention provides a kind of water alcohol acid aerosol finish paint, this water alcohol acid aerosol
