Abstract
The present invention relates to a water paint which can be diluted with water and contains low content of volatile organic compound, including base material and antirusting agent. It is characterized by that the base material resin contains (wt%) 4-8% of carboxylic ion hydrophilic group, and the described base material resin can be formed from linolenic acid, trimethylolpropane, one of isophthalic acid or phenylanhydride, maleic anhydride, trimellitic anhydride, acrylate, azodiisobutyronitrile, ethylene glycol monobutyl ether and butyl alcohol, and the antirusting agent is sodium nitrite. Said invented coating film can be quickly dried at normal temp., and possesses good antirusting property for metal base material and possesses excellent clecorative effect.
Description
A kind of Aqueou antirust decorative varnish of the present invention relates to a kind of water-borne coatings that contains the low level of voltile organic compound of dilutable water.
Though existing water-soluble alcohol acid has good sticking power to metal substrate, higher gloss and decorative effect are preferably also arranged, Air drying speed is slow, can not satisfy the requirement of some spraying coating process subsequent disposal; Though Waterborne Acrylate Coatings or acrylic latex Air drying speed are fast, to the poor adhesive force of metal, glossiness is low, and owing to film behind the Air drying without chemically crosslinked, poor water resistance, rustless property are not good; The antirust additive that traditional coating uses mostly is rust-stabilising pigment greatly, and this is inappropriate to requiring the transparent workpiece of filming.Though metal sulfamate salt rust-preventive agent is liquid, be difficult for being scattered in the water varnish, and poor storage stability.For these reasons, the present invention proposes a new technical scheme.
The objective of the invention is to: a kind of dilutable water, rate of drying is fast and film forming is transparent antirust decorative varnish are provided.
Purpose of the present invention can be achieved through the following technical solutions: a kind of Aqueou antirust decorative varnish, comprise base-material and rust-preventive agent, can select the inorganics Sodium Nitrite to make rust-inhibiting additive, characteristics are: binder resin contains the carboxylic acid ionic hydrophilic group of 4-8% weight part, described binder resin can comprise: linolenic acid, TriMethylolPropane(TMP), a kind of in m-phthalic acid or the phthalic anhydride, MALEIC ANHYDRIDE, trimellitic acid 1,2-anhydride, acrylate, Diisopropyl azodicarboxylate, butyl glycol ether, butanols is formed, and wherein comprises butyl acrylate in the acrylate, methacrylic ester, vinylformic acid, Diisopropyl azodicarboxylate; Described rust-preventive agent is Sodium Nitrite.
On the technique scheme basis, the weight percent of each composition is in the binder resin of a kind of Aqueou antirust decorative varnish of the present invention:
Linolenic acid 15-30%
TriMethylolPropane(TMP) 10-20%
M-phthalic acid 8-15%
MALEIC ANHYDRIDE 0.3-0.8%
Trimellitic acid 1,2-anhydride 4-7%
Butyl glycol ether 12-20%
Butanols 12-20%
The add-on of acrylate 8-12% Sodium Nitrite is the 0.2-0.6% of binder resin.
Superiority of the present invention is: binder resin is formed through chemically composited by Synolac and acrylate, in amine and after used water unrestrictedly dilute, and be equipped with water soluble anti-rust agent, have the rapid drying at normal temperatures of filming, coating has good anti-rust properties and fabulous decorative effect to metal substrate.
Embodiment; A kind of Aqueou antirust decorative varnish of the present invention and blending process thereof are: binder resin contains the carboxylic acid ionic hydrophilic group of 4-8% weight part, and described binder resin prescription is:
Linolenic acid 22
TriMethylolPropane(TMP) 16
M-phthalic acid 10
MALEIC ANHYDRIDE 0.5
Trimellitic acid 1,2-anhydride 6
Butyl glycol ether 17
Butanols 17
Butyl acrylate 5.55
Methacrylic ester 5
Vinylformic acid 0.9
Diisopropyl azodicarboxylate 0.05
The rust-preventive agent Sodium Nitrite.
The varnish blending process is: at first, add after 0.5 part of 22 parts of the linolenic acid, 16 parts of TriMethylolPropane(TMP)s, 10 parts of m-phthalic acids, MALEIC ANHYDRIDE, heat temperature raising carries out esterification to 170-180 ℃, keeps this temperature 3 hours, continue to be warming up to 220-230 ℃, be cooled to 170 ℃ less than 10 o'clock to acid number, add 6 parts of trimellitic acid 1,2-anhydrides again, be incubated under the 170-180 ℃ of condition, to acid number between 50-60, cooling then, adds each 17 parts in butyl glycol ether, butanols; Second step on above-mentioned technology basis, kept 100 ℃, added 5.55 parts of butyl acrylates, 5 parts of methacrylic esters, 0.9 part of vinylformic acid, 0.05 part of Diisopropyl azodicarboxylate and carried out polyreaction 4 hours, lowered the temperature; At last, add in the amine and above reaction product to PH7-8; Add cobalt naphthenate, manganese naphthenate siccative, stir evenly the back and add deionized water and be diluted to and be coated with 4 glasss of 20-30 seconds, add concentration at last and be 1.7 parts of 35% sodium nitrite in aqueous solution, stir evenly.Paint vehicle and water dissolubility are good, and the rust-preventive agent Sodium Nitrite is mixed with the aqueous solution earlier, add in the varnish again, and easy adding, good stability are arranged, and have good anti-rust properties in certain interpolation scope, are a kind of water-soluble varnish that the low level of voltile organic compound is arranged.Film performance:
Pencil hardness 1H
Gloss 60 ° 〉=90
Cross cut test, 1mm 1 utmost point
Water-fast 24 hours no changes
The salt spray resistance experiment was passed through in 140 hours
Film surface drying 15-20 minute it be more suitable for needing the quick-drying requirement of workpiece in some spraying coating process, have suitable hardness of film, better decorative appearance and water-fast erosion resistance such as gloss.
