Background
The leaves of the polyvinyl chloride material artware are attractive in appearance and resistant to washing, the key process for manufacturing the leaves of the polyvinyl chloride material artware is to print vivid and lively leaves on the polyvinyl chloride material, and the printing paste is of great importance.
The artware leaves on the market are generally glued and colored manually and then naturally dried, and have poor rubbing color fastness and washing resistance color fastness and low production efficiency.
In the prior art, solvent ink is also adopted for printing on polyvinyl chloride materials, and the printing ink has high solvent content and strong smell.
The prior art does not see the technical disclosure of printing paste for leaves of waterborne environment-friendly polyvinyl chloride material artware.
Disclosure of Invention
The invention aims to provide printing paste for polyvinyl chloride material artware leaves and a preparation method thereof; the printing paste for the leaves of the polyvinyl chloride material artware is water-based, environment-friendly, strong in film forming transparency, high in gloss, good in elasticity and good in oxidation resistance, and the printed polyvinyl chloride material is good in folding resistance, friction color fastness and washing color fastness, and the preparation method of the printing paste.
The invention relates to a preparation method of printing paste for leaves of polyvinyl chloride material artware, which comprises the following steps:
the raw materials are mixed according to the weight ratio
(1) Monomer emulsification: adding 10-15 parts of acrylic acid, 5-8 parts of acrylamide, 91-95 parts of butyl acrylate, 50-55 parts of acrylonitrile, 3-5 parts of hydroxyethyl methacrylate, 40-45 parts of methyl methacrylate, 3-5 parts of 1, 6-hexanediol diacrylate, 35-40 parts of styrene, 5-8 parts of fatty alcohol polyoxyethylene ether AEO9, 5-8 parts of sodium dodecyl benzene sulfonate and 250 parts of deionized water, and stirring for 10-15 minutes to prepare an emulsion for later use;
(2) initiating polymerization: adding 28-32% of the total weight of the emulsion into a reaction kettle, heating to 75-80 ℃, adding 0.8-1.1 part of initiator sodium persulfate and 10 parts of deionized water to prepare a sodium persulfate aqueous solution for initiation, wherein the emulsion is changed from milky white to light blue, controlling the temperature to 82-85 ℃ after 20-30 minutes, dropwise adding the rest emulsion, simultaneously dropwise adding 1.1-1.3 parts of sodium persulfate and 10 parts of deionized water to prepare the sodium persulfate aqueous solution, after dropwise adding for 1-2 hours, controlling the temperature to 85-90 ℃, keeping the temperature for 2-3 hours, cooling to 30-40 ℃, and adjusting the pH value to 7 +/-0.5 by using 19-21% ammonia water in mass percentage concentration to obtain a polymerization emulsion;
(3) compounding: adding 8-12 parts of polyacrylate anti-seepage thickening agent, 3-5 parts of isooctanol polyoxyethylene ether wetting agent, 5-8 parts of polyurethane associated leveling rheological agent and 12-15 parts of polyol anti-blocking agent, uniformly stirring, filtering and discharging to obtain a printing paste product;
chemical indexes of the product are as follows:
appearance: white paste
Ionic property: yin (kidney)
pH value: 7 +/-0.5
Solid content: not less than 50 percent.
The printing paste of the invention needs low viscosity and good permeation effect, so that the colors of the front and the back of the printed product are close to each other, the prepared leaves are more vivid, and the experiment proves that the water holding capacity of the common thickening agent is poor, and the permeation phenomenon can occur when the viscosity of the printing paste is low. The invention selects the polyacrylate anti-seepage thickener, can ensure that the seepage phenomenon does not occur when the viscosity of the printing paste is lower, ensures that the printed product has good seepage effect and the colors of the front side and the back side are close.
The isooctanol polyoxyethylene ether wetting agent can be an isooctanol polyoxyethylene ether JFC wetting agent, has a good wetting effect, and is environment-friendly. Because the hydrophilicity of the polyvinyl chloride is relatively poor, the wetting effect of the printing paste can be improved by adding the isooctanol polyoxyethylene ether wetting agent, so that the printing paste can have better level-dyeing property on the polyvinyl chloride material, and meanwhile, the permeation effect can be improved. And other nonylphenol polyoxyethylene ether wetting agents are not adopted because of containing APEO and not being environment-friendly.
The invention adopts the polyurethane associated leveling rheological agent, which can make the rheological property of the printing paste better and can continuously and rapidly print.
The polyhydric alcohol anti-blocking agent can be glycerol. Experiments prove that compared with anti-blocking agents such as ethylene glycol and the like, glycerol has better moisturizing effect. Because the solid content of the printing paste is high, the film is easy to form in the printing process, and the phenomenon of plate blocking can occur, so that the printing machine cannot continuously run.
The emulsifier selected by the invention is an anionic and nonionic emulsification system of sodium dodecyl benzene sulfonate and fatty alcohol-polyoxyethylene ether AEO9, and compared with a nonionic emulsification system commonly used for emulsion polymerization, the raw material combination emulsification effect of the invention is better, and the emulsion is more stable.
The polymerization temperature of the invention is 82-85 ℃ which is higher than the temperature of 80-82 ℃ of the common emulsion polymerization, and because the heat preserving temperature is high and the monomer is easy to react, the monomer can react relatively completely, and the using effect of the polymerized product is better.
The heat preservation process of the emulsion polymerization is directly heat preservation at 82-85 ℃ in the reaction process, and the heat preservation process after the reaction is finished is heat preservation at 85-90 ℃ for 2-3 hours, so that the monomer is relatively completely reacted, the content of residual monomer is lower, and the odor of the product is mainly caused by the residual monomer, so that the product has the advantages of lower odor and more environmental protection.
The acrylamide polymer in the raw material proportioning combination has a bridging function, can provide structural strength and enables the product to have good oxidation resistance; acrylonitrile is used as a synthetic monomer of rubber resin, so that the wear resistance and the elasticity are good; methyl methacrylate is a synthetic monomer of organic glass, and the polymer has good transparency and high gloss; styrene is commonly used to produce glossy resins. Through repeated experiments, the invention selects the combination of acrylonitrile, styrene, methyl methacrylate and acrylamide which are hard monomers with higher glass transition temperature, and uses the proportion in the invention, the product stability is good, meanwhile, the product has good wear resistance and oxidation resistance, and the polymer film forming is continuous, so that the polymer has good transparency and high gloss. Other hard monomers with higher glass transition temperature, such as ethyl methacrylate, isobornyl methacrylate and the like, have been tested, but are easy to explode and polymerize in the production process, and the performances are poor.
The cross-linking agent 1, 6-hexanediol diacrylate in the raw material proportioning combination is a bifunctional functional monomer, and the cross-linking agent hydroxyethyl methacrylate contains polymerizable vinyl and active hydroxyl. And the two crosslinking agents do not contain formaldehyde, so that the produced main product is environment-friendly. And the common N-hydroxymethyl acrylamide crosslinking agent contains formaldehyde, which is not environment-friendly.
The acrylic acid selected from the raw material proportioning combination is a functional monomer for providing carboxyl, so that the stability of the emulsion is improved, and the crosslinking catalysis effect is realized. And the stability of the emulsion is poor in the experimental production process of carboxyl monomers such as methacrylic acid, maleic acid and the like.
The selection of the soft monomer is also important, the polymerization stability of the soft monomer such as butyl acrylate is relatively better than that of ethyl acrylate and the like through experiments, the butyl acrylate is selected as the soft monomer, the butyl acrylate is matched with the hard monomer and the cross-linking agent to produce the high-solid-content printing paste product, the cross-linking points with the polyvinyl chloride material are more during film forming, and the friction color fastness and the washing color fastness of the printed product can be improved.
The printing paste is water-based environment-friendly printing paste, and has the advantages of strong film-forming transparency, high gloss, good elasticity and good oxidation resistance. The printed polyvinyl chloride material has improved folding resistance, good color fastness to rubbing and washing, and good quality and high production efficiency, and the printed product is directly cut into the tree leaf artware.
