Abstract
The invention discloses an environment-friendly alkyd coating and relates to an alkyd coating which does not contain aromatic solvent and harmful pigment and filler and has environmental protection characteristics and excellent appearance performance. The alkyd coating consists of environment-friendly alkyd resin, aromatic-free solvent naphtha 200#, pigment and filler, dispersing agent, rare-earth complex drier and anti-settling agent, and the alkyd coating can be adjusted to various colors as required. By using the coating, the influence on the human body and the living environment by the alkyd coating which is used most and releases the pungent odor of the aromatic solvent during construction can be solved. During the synthesis of the alkyd resin, the polyether polymer is mixed with the water and then mixed with the aromatic-free solvent 200# to be used as the solvent, the environment-friendly and energy-saving effect can be realized, the anti-corrosion performance and dryness of the coating are greatly improved by the produced alkyd resin and the alkyd coating, as the alkyd coating does not contain aromatic solvent and pungent odor, the alkyd coating has safe and convenient use and environmental protection characteristics, and is applicable to various construction methods, the coating application is not limited by season, so that a large amount of coating cost can be saved and the service life is prolonged. The alkyd coating is widely on steel structure, pipeline, storage tank, tank car and equipment as surface anti-corrosion coating in the industries like chemical industry, machinery, shipping industry and metallurgy.
Description
Technical field
The present invention relates to a kind of protective system, relate in particular to a kind of inside and outside surface of steelwork that is applicable to, have the excellent gloss and the alcohol acids environmental protection coating material of mechanical and physical performance and aromatic free solvent.
Background technology
Synolac is the artificial synthetic resin who is applied to the earliest in the coating, and its dryness, gloss, hardness, weather resistance all are that oil-base paint is inaccessiable far away, makes coating really get into the category of " coating " from original " paint ".Synolac can be made into varnish, enamel paint, priming paint, putty and water-miscible paint; Because of single component, cheap, gloss is full etc., and factor is widely used in coating industry; Coating accounts for 40% of ultimate production at home, and therefore, Synolac and made lacquer have very consequence at coating industry.
Synolac is the polymkeric substance that is obtained through copolycondensation by oil, lipid acid, polyprotonic acid and polyvalent alcohol; In building-up reactions; A large amount of organic solvents like No. 200 industrial napthas, YLENE, terebinthine adding, make and contain a large amount of aromatic solvents in the Synolac; Not only have pungent smell, and bring harm for human body and environment.According to statistics, the aromatic solvent content in the general Synolac is 30～40%, and alkydpaints is especially because the further adding of solvent makes aromatic solvent content be increased to 40～60%; The volatilization and the discharging of a large amount of aromatic solvents make disperses such as benzene, YLENE, polycyclic aromatic hydrocarbons in atmosphere, work the mischief to environment.
The present invention at first is the synthetic environment-friendly Synolac, adopts refining soya-bean oil, season the eleventh of the twelve Earthly Branches tetrol, Tetra hydro Phthalic anhydride as resin raw material, and in processing medium oil alkyd, control refluxes to releasing sneaking into of solvent.Adopt the polyethers superpolymer to mix back and No. 200 solvent of removing aromatic hydrocarbons with water as solvent, no longer adding contains No. 200 industrial napthas, YLENE, the turps equal solvent of aromatic hydrocarbons, but with green No. 200 solvents (treated aromatic free), water, polyethers superpolymer as mixed solvent; Reach the environmental protection and energy saving effect; The resin property of processing is with to contain aromatic hydrocarbons Synolac performance suitable, sticking power, gloss; Dryness is better, has removed irritating smell.
In the alkydpaints optimization of formulation, heavy metallic pigment such as that the color stuffing of being selected for use requires is not leaded, mercury satisfies the requirement of nontoxic industry; In paint film, have good closure and Corrosion Protection, make coating have certain rheological, reduce the cost of coating; Therefore; Through orthogonal test repeatedly, it is main rust-stabilising pigment that this patent is selected titanium white, zn phosphate for use, and filler is selected permanent white for use.On choice of Solvent, select aromatic free green No. 200 solvents, make in the coating also aromatic free solvent, have good construction performance and environmental-protecting performance.In the selection of siccative, select the compound rare-earth siccative, form by different zincic acid cerium, the compound preparation of different zincic acid aluminium, regulate curing reaction speed, also improve the cross-linking density and the snappiness of filming, also have the innovation part.Its mechanical and physical performance and the erosion of each item comprehensive anticorrosive, ageing-resistant index all are much higher than each item performance index of other alkydpaints, and no aromatic solvent, asepsis environment-protecting that this coating has have uniqueness.
Summary of the invention
The technical problem that the present invention will solve is that a kind of Synolac of aromatic free solvent is provided and plants the alcohol acids single component environment-friendly type coating that resin makes thus; In order to solve the protection against corrosion difficult problem of inside and outside external coatings such as steel, timber; And coating has no aromatic solvent and no poisonous pigment; Be fit to various constructional methods, application does not receive characteristics such as season limit, and the present invention also provides the preparation method of said Synolac.
