Description
Technical field
The present invention relates to a kind of pressure sensitive adhesive, particularly a kind of can the pressure sensitive adhesive of silk screen printing.
Background technology
Pressure sensitive adhesive is a kind of polymer emulsion, add thermal initiation form adding appropriate thermal initiator in Acrylic Acid Monomer emulsification to water, during synthesis, system must be in environment (" polymer emulsion composition principle properties and application (second edition) " Cao Tongyu of anaerobic, Liu Qingpu, Hutchinson, Paul C. is compiled, Chemical Industry Press).The synthesis patent of pressure sensitive adhesive is many, examination enumerates one or two, pressure sensitive adhesive disclosed in CN1824721 is formulated in right amount by 54 ~ 58 parts, water, sodium lauryl sulphate 0.30 ~ 0.40 part, ammonium persulfate 0.32 ~ 0.42 part, mixture 41 ~ 45 parts, ammoniacal liquor, wherein mixture is by vinyl acetate, butyl acrylate, vinylformic acid is mixed with the ratio of 15: 4: 1; The compound method of described pressure sensitive adhesive is: water intaking, heat temperature raising, and slowly adds sodium dodecyl; When temperature is increased to 80 ~ 90 DEG C, add ammonium persulphate; Keep temperature to be 80 ~ 90 DEG C, drip mixture; Be incubated and stir 30 minutes, being progressively cooled to 55 DEG C, adding ammoniacal liquor adjust ph to 8; Continuing to be cooled to temperature is 45 DEG C, and preparation completes.CN101698784A pressure sensitive adhesive and metal conductive particles form, wherein, metal conductive particles accounts for 30 ~ 80% of pressure sensitive adhesive gross weight, and pressure sensitive adhesive is made up of each component of following weight percent: acrylic acid or the like soft monomer 30 ~ 50%, acrylic acid or the like hard monomer 5 ~ 20%, containing carboxyl class function monomer 0.5 ~ 2.5%, hydroxyl class cross-linking monomer 0.5 ~ 2.5, non-alcoholic solvent 40 ~ 60%, oil-soluble initiator 0.2 ~ 2.0% and mercaptan type chain transfer agent 0.01 ~ 0.2%.These patents mainly pay close attention to the synthesis of emulsion itself, and in the emulsion applications of rear end, research is few.The present inventor finds that in actual practice common emulsion is difficult to carry out silk screen printing, mainly because general emulsion viscosity is too little, too thin to such an extent as to cannot levelling thus leave grid lines after silk-screen, viscosity can be made to increase a lot of times if add general thickening material thickening, but equally cannot levelling after silk-screen, because thickening means that levelling property is poor, and glue itself is too strong again to the sticking power of silk screen, so leave grid lines after silk screen flicks from glue plane.
Contriver conscientiously have studied the reactive force between relevant silk-screen printing process and each material, thus completes the present invention.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can the pressure sensitive adhesive composition of silk screen printing, this pressure sensitive adhesive composition viscosity is very large, and blanking is quick and complete, not sticky net hole, and levelling effect is fine, bubble-free after glue-line drying, without pit.
Technical problem to be solved by this invention is achieved by the following technical programs:
Can the pressure sensitive adhesive composition of silk screen printing, be made up of following six kinds of components:
Component A: conventional pressure sensitive adhesive;
B component: thickening material, consumption is the 0.1-3% of component A consumption, if do not have thickening effectiveness lower than 0.1%, if be greater than 3% can affect sizing and its cohesive force.；
Component C: flow agent, consumption is the 0.05-0.5% of component A consumption, is greater than the cohesive force that 0.5% can damage glue;
D component: the solvent emulsion particle in component A pressure sensitive adhesive being had to certain swelling property, addition is the 1-10% of component A consumption, this solvent is different along with the difference of used pressure sensitive adhesive, such as, when conventional pressure sensitive adhesive uses flame retardant type pressure sensitive adhesive (viscosity is 3000mPa.S) of Nantong Mei Tian adhesive tape company limited, we find to adopt the ketones solvent such as acetone, butanone to have best swelling effect, and apparent upper viscosity increases at most; If composition only has A, B, component C, the viscosity of pressure sensitive adhesive can be increased to 30000mPa.S from 3000mPa.S, if but the D component adding 5% just can make viscosity jump to 300Pa.S, this viscosity only relies on B component thickening material to realize;
Component E: to the solvent of silk printing screen material nylon without wetting ability, consumption is the 1-5% of component A consumption, when silk-screen this solvent with other composition of pressure sensitive adhesive along mesh under the effect of scraper, speed away mesh, is attached on base material.；
F component: non-ionic type mould inhibitor, consumption is the 0.01-0.1% of component A consumption.
Further, as wherein a kind of preferred version of technique scheme, this can the pressure sensitive adhesive composition of silk screen printing, is made up of following six kinds of components:
Component A: the flame retardant type pressure sensitive adhesive of Nantong Mei Tian adhesive tape company limited;
B component: the AT-70 alkali swelling type thickening material of Beijing Proview emulsion company limited, consumption is the 0.1-3% of component A consumption;
Component C: the DN-108 that Nanjing De-Nol chemical industry provides, consumption is the 0.05-0.5% of component A consumption;
D component: ketones solvent, as acetone, butanone etc., consumption is the 1-10% of component A consumption;
Component E: hexalin, consumption is the 1-5% of component A consumption;
F component: isothiazolinone, consumption is the 0.01-0.1% of component A consumption.
The present invention has following beneficial effect:
The present invention is by the pressure sensitive adhesive of routine and thickening material, flow agent, the brand-new pressure sensitive adhesive that the emulsion particle in component A pressure sensitive adhesive had to the solvent of certain swelling property, be made into proper ratio without the solvent of wetting ability, non-ionic type mould inhibitor silk printing screen material nylon, this pressure sensitive adhesive viscosity is very large, blanking is quick and complete, not sticky net hole, levelling effect is fine, bubble-free after glue-line drying, without pit.
