A kind of polyacrylate dispersion stamp rubber cement antitack agent and preparation method thereof
Technical field
The present invention relates to a kind of polyacrylate dispersion stamp rubber cement 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 the attention of domestic and international colourist to 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 COAT PRINTING technology is easy, there is not sewage discharge to pollute, eco-friendly superiority looms large, thereby develops very fastly, and the share that COAT PRINTING occupies 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 much the trend that replaces dye printing up to 80%.The COAT PRINTING of various countries shared ratio in textiles is different, and the U.S. accounts for 80%, and West Europe accounts for 60 one 70%; India accounts for 60%, and Japan accounts for 30%, though China's textile coating stamp starting is later; But development is very fast; In recent years, the ratio of COAT PRINTING is also in rising trend, has surpassed 50% of total stamp amount so far.Along with improving constantly of living standards of the people; The consumer not only to garment material require increasingly high; And to indoor textile decoration with the requirement of cloth also progressively to middle and high shelves development, in order to adapt to different consumer demands, COAT PRINTING will be further developed.
Owing to have good film forming, adhesion strength, have heat-resisting, resistance to oxidation, weatherability simultaneously, not flavescence, biodegradable, advantages such as environmental protection, polyacrylate dispersion stamp rubber cement becomes rubber cement kind the most frequently used in the COAT PRINTING.But the characteristic of polyacrylate self molecular structure has the shortcoming of hot sticky cold crisp again, be difficult to again reach textiles particularly the printing quality of knitwear require: soft, the good springiness of comfortable feel; Good stretching resilience is arranged; Tack-free under the normal temperature; To extruding again after the stretching of stamp position, unclamp naturally under the normal temperature, do not stick together; The flower bit position is printed in doubling, cooling naturally after 70 ℃ * 24h * 5kg weight, and broken grade for performance requirement can cannot not drawn back stickingly in doubling flower position.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 or the like, these methods all 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 proportioning flexibly according to the actual conditions of polyacrylate dispersion stamp rubber cement, the polyacrylate dispersion stamp rubber cement that obtains suiting.Therefore, the method for interpolation antitack agent is the method for the most generally using.
At present the most frequently used antitack agent is a paraffin, 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 break easily, melt easily 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.
To above problem; The present invention provides a kind of polyacrylate dispersion stamp rubber cement antitack agent, goes for acrylic acid ester emulsion stamp rubber cement, polyacrylate/polyurethane polyureas acrylic acid ester emulsion stamp rubber cement, polyurethane polyureas acrylic acid ester emulsion stamp rubber cement 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 stickingly, and water-fast advantage such as wash has solved the technical problem that exists in the use of above-mentioned polyacrylate dispersion stamp rubber cement effectively.
