Description
Technical field
The present invention relates to a kind of polyacrylate dispersion printing mortar antitack agent and preparation method thereof, belong to the screen printing technique field.
Background technology
COAT PRINTING is by means of adhesive coating to be adhered to the printing technology that fiber surface obtains required pattern.Modern age, COAT PRINTING originated in the Ardye system of nineteen thirty-seven Interchemical company, caused domestic and international colourist to the attention of COAT PRINTING, then was after the Aeramin F type textile printing pigment appearance of nineteen fifty-one Germany Bayer company.The sixties synthetic fiber development, the rise of petrochemical industry and the large-scale production of chemical fibre textile provide the opportune moment of displaying one's talent for the COAT PRINTING technology.Because the COAT PRINTING simple process, there is not sewage discharge to pollute, eco-friendly superiority looms large, thereby develops very fastly, and the share that COAT PRINTING is occupied in stamp market, the world increases year by year.Present global COAT PRINTING fabric accounts for whole PRINTED FABRIC more than 55%, and especially in the U.S., the COAT PRINTING proportion has greatly the trend that replaces dye printing up to 80%.The COAT PRINTING of various countries shared ratio in textiles is different, the U.S. accounts for 80%, West Europe accounts for 60 one 70%, India accounts for 60%, and Japan accounts for 30%, although China's textile coating stamp starting is late, but development is very fast, in recent years, the ratio of COAT PRINTING is also in rising trend, has surpassed so far 50% of total stamp amount.Along with improving constantly of living standards of the people, the consumer is not only more and more higher to the requirement of garment material, and to indoor textile decoration with the requirement of cloth also progressively to the medium and high classes development, in order to adapt to different consumer demands, COAT PRINTING will be further developed.
Owing to having good film forming, adhesion strength, have simultaneously heat-resisting, resistance to oxidation, weatherability, not flavescence, biodegradable, the advantages such as environmental protection, the polyacrylate dispersion printing mortar becomes rubber cement kind the most frequently used in the COAT PRINTING.But the characteristic of polyacrylate self molecular structure has again the shortcoming of hot sticky cold crisp, be difficult to again reach textiles particularly the printing quality of knitwear require: comfortable feel is soft, good springiness; Good tensile property is arranged; Tack-free under the normal temperature; To again extruding after the stretching of stamp position, naturally unclamp under the normal temperature, do not stick together; The flower bit position is printed in doubling, and naturally cooling can cannot not pulled open stickingly broken grade for performance requirement to the folding flower position after 70 ℃ * 24h * 5kg weight.For overcoming this shortcoming, people constantly release antiseized method.Such as the vitrification point that improves acrylate copolymer, form the soft nucleocapsid structure of Hard Roll, with modifications such as polyurethane, polysilane etc., these methods have certain effect to improving viscosity undoubtedly, but all will reduce some performance of product or raise the cost.The method that adds antitack agent is simple and easy to control, can change flexibly proportioning according to the actual conditions of polyacrylate dispersion printing mortar, the polyacrylate dispersion printing mortar that obtains suiting.Therefore, the method for interpolation antitack agent is the method for the most generally using.
The most frequently used antitack agent is paraffin at present, floats over the surface of stamp with the form that is separated, and reaches anti-adhesion effects.But belong to brittle solid during paraffin low temperature, stretch and easily break, easily melt during high temperature, anti-adhesion effects reduces.
Disclosed antitack agent is one or more in stearic acid isooctyl, Tissuemat E, the different tridecanol fat of stearic acid, the mineral oil among the patent CN102286888A, its consumption is the 1.5-2.5% of mass fraction, it has used synthetic wax in an embodiment, and effect is better, but the scope of application is narrower.
For above problem, the invention provides a kind of polyacrylate dispersion printing mortar antitack agent, go for acrylic acid ester emulsion printing mortar, Polyacrylate/polyurethane polyacrylate dispersion printing mortar, polyurethane polyureas acrylic acid ester emulsion printing mortar system.It comprises silicone oil, mineral oils, vegetable oil, PE wax, with high-grade aliphatic ester at least two kinds.Such antitack agent has stable chemical performance, and feel is smooth, and ABRASION RESISTANCE is good, does not return the advantages such as sticking, water-fastness, has effectively solved the technical problem that exists in the use procedure of above-mentioned polyacrylate dispersion printing mortar.
