The specific embodiment
Below surface treating agent for fabric coating of the present invention and preparation method thereof is described in further detail.
Anti-ultraviolet function in this invention is that the acrylic monomers with the hydroxyl with anti-ultraviolet function is a principal component, has wherein also added the acrylic monomers with other effect groups, the polyethylene series monomers, and copolymer and solvent form.
Employed acrylic resin is that the acrylic monomers that contains the hydroxyl with ultraviolet radiation absorption function is arranged in this invention, contains the non-acrylic monomers composition that acts on the acrylic monomers of base and contain carbonyl.
The special envoy has used the acrylic monomers that has the hydroxyl that absorbs ultraviolet function in the Chemical formula 1 in this invention, thereby has improved ultraviolet weatherability.Above-mentioned monomer has carried out commercialization production in 0tsukaChemical company, and Chemical formula 1 is that code name is the product of RUVA-93.
Chemical formula 1
Contain acrylic monomers and account for 0.5 ~ 5% by weight approximately with the ultraviolet function of absorption.When content is lower than 0.5, can causes the low of long-term weatherability, and influence performance; When content is higher than 5, the shortcoming that just has the product cost of causing to rise.
In addition, as the acrylic monomers that contains non-effect group, specifically, be by methyl methacrylate, ethyl methacrylate, isobutyl methacrylate, butyl methacrylate
Hexyl methacrylate, methacrylic acid 2-Octyl Nitrite, methyl acrylate, propyl acrylate, isobutyl acrylate, butyl acrylate, 2 ethyl hexyl acrylate, acrylic acid n-octyl, cyclohexyl methacrylate, tert-butyl acrylate selects one or more as the proportioning material in the cyclohexyl acrylate.
This type of, the basic acrylic monomers of non-effect accounts for the 50-70% (by weight) of unsaturated monomer, when its content is lower than 50%, can makes coating really up to the mark, thereby reduce scratch-proofness, and when content was higher than 70%, then the mistake of coating was low and influence is used.
The acrylic monomers of above-mentioned hydroxyl is by 2-hydroxy acrylic acid ethyl ester, 2-hydroxymethyl propyl acrylate, 4-hydroxy acrylic acid butyl ester, 2-hydroxy acrylic acid ethyl ester, 4-hydroxymethyl butyl acrylate, the acrylic acid caprolactone, methacrylic acid caprolactone, 2,3-dihydroxy propyl acrylate, 2,3-dihydroxy propyl methacrylate, the raw material of one or more in polypropylene denaturing acrylamide acid esters and the polypropylene sex change methacrylate etc. is made.
Polylactone denaturing acrylamide acid esters or polypropylene denaturing acrylamide acid monomers should account for 10-70% (by weight) in the acrylic monomers of the hydroxyl that specially uses in this invention.
The hydroxy acryl acid monomer should account for the 15-35% (by weight) of unsaturated monomer total amount, when content is lower than 15%, can cause glossiness low; When content surpasses 35%, can cause bad influence to fabric coating film material resistance to water etc.
In addition, the acrylic monomers that contains carbonyl can be used acrylic acid, methacrylic acid, maleic acid, itaconic acid, crotonic acid etc.
The above-mentioned acrylic acid that contains carbonyl accounts for the 1-5% (by weight) of total unsaturated monomer, and is low if content is lower than the density of 1% o'clock glue connection, and acid resistance is descended; When surpassing 5% (by weight), resistance to water is descended.
Moreover, the ethene series monomers such as the sterol of this invention, polyethylene toluene selects more than one uses in polyethylene acetate fiber and the a-methyl sterol, and wherein sterol alcohol is comparatively suitable.
This type of ethene series monomers accounts for below 30% of unsaturated monomer total amount, if surpass the gloss that this value then can reduce coating.
Polymerization in this invention begins agent 2,2-azo two (2,2 methylbutyronitrile) 2,2'-Azobis(2,4-dimethylvaleronitrile), and the peroxidating benzil, peroxidized t-butyl perbenzoate, 2-ethyl tert-butyl peroxidating capronate, the tert-butyl hydroperoxide acetic acid esters,
The content that polymerization begins agent accounts for the 2-20% (by weight) of unsaturated monomer total amount, if content not in this scope, then can reduce water resistance.
Employed solvent has toluene in this invention, aromatic hydrocarbons series such as dimethylbenzene; Butanone, pentanone, hexanone, methyl-n-butyl ketone, the 3-hexanone, the 2-heptanone, methylisobutylketone waits ketone; Methyl acetate, ethyl acetate, propyl acetate, isopropyl acetate, butyl acetate, acetate methyl 2-ethoxy ethyl ester, acetate 2-ethoxy ethyl ester, acetate butyl 2-ethoxy ethyl ester, the acetate card is finished esters solvents such as ester; Propyl alcohol, isopropyl alcohol, n-butanol, isobutanol, the tert-butyl alcohol waits alcohols solvent.
In addition, also can comprise the chain mobile agent of polymerization as required, its content accounts for below 10% (by weight), when content surpasses 10%, (Huang) look phenomenon can occur becoming.
Surface conditioning agent in this invention is as described below with method for producing acrylic acid, toluene, aromatic hydrocarbons classes such as dimethylbenzene, solvent or alcohols solvent, add the basic acrylic monomers of non-effect in esters solvent or the alcohols solvent, the hydroxy acryl acid monomer, containing the carbonyl acrylic monomers has hydroxy acryl acid monomer and the polyethylene kind monomer that absorbs ultraviolet function and adds the polymerization of thermal decomposition type and begin agent, 80-180 ℃ reaction temperature, under the mechanism of free radical, as with the polymerisation in solution manufactured, can obtain solid content 30-80%, mean molecule quantity 5000-50000, hydroxyl 40-180, acid number 3-30, the acrylic resin of free ionization temperature (Tg)-10～70 ℃.
The hydroxyl value of the acrylic resin that obtains like this is lower than 40, can cause the crosslink density of coating not enough, above 180 o'clock, though improved crosslink density rerum natura is improved, but can improve surface tension and reduce the diffusivity of coating, cause bad appearance of coat, thereby cause solvent, resin and base fabric handle and commerciality lowly.So, can not adopt.
Moreover acid number is lower than at 3 o'clock, has reduced sour inside catalytic action, solidifies carry out slow, and adhesive force of coatings is reduced, and surpasses 30, though can accelerate curing reaction,
The resistance to water and the weatherability of coating are bad, unavailable.
Existing acrylic resin is if use the isocyanates group, melmac, sour catalyst, mixing such as additive and solvent, the oilcloth finishing agent of making, solution state and harden after coating the xanthochromia phenomenon can take place.The reason of similar xanthochromia phenomenon is mainly because of isocyanates group and sour catalyst, this invention is for this phenomenon of MIN control, and reduced the consumption of above-mentioned beginning agent as far as possible, and carry out sufficient circular response and reclaim foreign matter in the reaction system in case of necessity, interpolation is as 1076,900 grades 0.05～3% (by weight) of (CYTEC) company of antioxidant.Antioxidant can directly add in the acrylic resin product, also can add in manufacture process.
