Description
The present invention relates to a kind of hardware and antiseptic water soluble anti-rusting paint of material surface and preparation method of being used for.This priming paint can replace solvent-borne type red iron oxide alkyd primer and phenolic group priming paint fully.
According to statistics, hardware that the whole world is scrapped by corrosion and material reach more than 100,000,000 tons every year, account for the 20-40% of world steel annual production, and the financial loss that annual because metallic corrosion causes to Chinese national economy is up to hundred million yuan of 100-150.This shows that how the rotproofing of hardware and material has important practical sense.China is that the industry of material is annual for rust protection need consume a large amount of rust-proofing primers with the iron and steel, and at present domestic general be solvent-borne type red iron oxide phenolic resin primer and red iron oxide alkyd primer.They are all with toluene, and the 200# solvent oil is a solvent, cost height not only, and environmental pollution is also very serious.
For addressing the above problem, develop the attention that novel priming paint has obtained scientific and technical personnel.External initial stage in sixties water soluble resin lacquer begins to have obtained development, and obtained widespread use industrial, water soluble resin as the water soluble resin lacquer mainly contains water-soluble epoxy ester, water soluble alkyd resin, Polyester Resin Water Soluble, water soluble acrylate resin etc., and these water soluble resins are mainly used in the manufacturing electrocoating paint.The water soluble acrylic resin has obtained application as rust-proofing primer at aspects such as hardware, coiled material, metal tin, automobiles in recent years.The clear 55-52354 of Japanese Patent has introduced acrylate copolymer emulsion and has been used for the anticorrosion of metal.Industrial finish 5,1986, Vol62 Vo5 p46 has enumerated the water-borne coatings that various resins such as epoxy ester, vinylformic acid, alkyd and polyester are prepared, these water-borne coatingss are all different at aspects such as sticking power, rust-preventing characteristic, hardness, snappiness, water tolerance as the priming paint of hardware and utensil, cost is also different, but all not really desirable.
Polymer Paint Colour Journal Vol154 No4125 P578 has introduced vinylchlorid-vinylidene chloride-acrylic terpolymer and has obtained satisfied application as rust-proofing primer.But the rust-proofing primer new variety of above introduction are more expensive except price, outside raw material sources lack, and in the drying rate of paint film, levelling property, aspects such as hardness are still not as the solvent-borne type rust-proofing primer.
The purpose of this invention is to provide a kind of water soluble anti-rusting paint and preparation method, this method technology is simple, the starting material source is rich and easy to get, fundamentally cancelled benzene class noxious solvent, removed the environmental pollution that exists in priming paint production and the construction and to the harm of the person, significantly reduced material cost and improve the quality of products.
The object of the present invention is achieved like this: this priming paint is to be solvent with water, with the new type water-solubility resin is base-material, and adding starting material component is lead naphthenate, manganese naphthenate, light calcium carbonate, talcum powder, process white, red iron oxide, the mixing in the lacquer still of joining in high-speed stirring grinds dispersion through shredder and forms.Concrete feed composition and preparation technology are as follows: at first prepare paint vehicle, its raw material weight per-cent is hemp oil 15-20, cis-butenedioic anhydride 3.5-5.5, hydrocarbon resin 4-6, ammoniacal liquor 3.5-5.5, butanols 3.5-5.5, deionized water 55-65, take by weighing hemp oil according to quantity and put into synthesis reactor, under agitation condition, cis-butenedioic anhydride and the hydrocarbon resin that crushes added in the still, heat to 205-215 ℃, be incubated 1.5-2 hour, measuring viscosity stops to heat for 6-8 second, be cooled to 100 ℃ and add butanols, be cooled to 60 ℃ and add ammoniacal liquor, when the reaction solution pH value reaches 8.0-8.5, it is 1.0-1.5 second that the adding deionized water is diluted to viscosity, promptly making paint vehicle, is paint vehicle 50-55 by raw material weight per-cent then, lead naphthenate 1-2, manganese naphthenate 1-2, light calcium carbonate 8-12, talcum powder 4-6, process white 8-12, red iron oxide 18-24 takes by weighing to put into and joins the lacquer still, under high-speed stirring, add each component mixing respectively, grind through shredder and disperse, fineness is finished product below reaching 50 μ m.
The present invention is solvent and thinner owing to adopting aboundresources, low-cost water, with domestic hemp oil cheap and easy to get is main raw material, be neutralized into amine salt through acidifying, and produce new type water-solubility synthetic resins for the modification component with the unsaturated hydrocarbons resinoid that petroleum cracking makes through catalyzed polymerization, adding multiple additives and rust-stabilising pigment and pigment extender forms through mixing, grinding, so preparation technology is simple, the processing ease support is held, and raw materials cost and manufacturing cost are very low.Particularly cancelled and having cost an arm and a leg and the benzene class noxious solvent of market shortage, fundamentally removed the environmental pollution that exists in priming paint production and the construction, disaster hidden-trouble, to operator's harm, significantly improve the bonding force of this product to the sticking power and the various finish paints of metallic surface, can replace solvent-borne type red iron oxide alkyd primer and red iron oxide phenolic resin primer fully, have tangible economic benefit and social benefit, can wide popularization and application.
