Abstract
Acrylate pressure sensitive adhesive modified by hydrogenated rosin relates to the material that is used as tackiness agent except that glue.
For acrylate pressure sensitive adhesive modified, we have developed a kind of acrylate pressure sensitive adhesive modified by hydrogenated rosin stick.It is by butyl acrylate (Octyl acrylate), vinyl acetate between to for plastic, vinylformic acid N---and the technological process of n-methylolacrylamide, hydrogenated rosin glyceride, emulsifying agent, ammonium persulphate, the frequent regulation pressure-sensitive adhesive of sodium bicarbonate is made.This tackiness agent is performance stable than existing acrylate pressure sensitive adhesive not only, holds viscosity and stripping strength meets or exceeds similar products at home and abroad; And cost greatly reduces, thereby has opened up the new purposes of staybelite.
Description
It relates to except that glue, as the material of tackiness agent.
The acrylic solution Polymeric Pressure Sensitive Adhesive that the sixties in this century are brought into use; have performances such as good weathering resistance, oil resistant, water-fast, resistance to oxidation, anti-solvent; because this pressure sensitive adhesive is without organic solvent; environment protection, production safety, raw-material utilization all there is positive effect; have the generation, the save energy that reduce public hazards and fire, alleviate characteristic and advantage such as labor strength; but the Octyl acrylate price is more expensive in this pressure sensitive adhesive composition; consumption increases the cost up that makes product, can not obtain favorable economic benefit.In line with reducing cost, increase economic efficiency, open up the purpose of the new purposes of staybelite, we have developed the acrylate pressure sensitive adhesive modified by hydrogenated rosin stick, the mix monomer that this tackiness agent is made up of adhesion composition, interior poly-composition, modification composition, interpolation emulsifying agent, initiator Ammonium Persulfate 98.5 and buffer reagent sodium bicarbonate are made through the conventional manufacture craft process of pressure-sensitive adhesive, and wherein adhering to composition is esters of acrylic acid, and it accounts for 40 to 60% of mix monomer amount.Interior poly-composition vinyl acetate between to for plastic accounts for 10～30% of mix monomer, staybelite accounts for 10～35% of mix monomer in the modification composition, vinylformic acid accounts for 4～6% of mix monomer, it is 0.6% of mix monomer that 4～5% emulsifying agent polyoxyethylene glycol phenyl Octyl Ether that the linking agent N hydroxymethyl acrylamide accounts for mix monomer add 5% or the sodium lauryl sulfate amount that polyvinyl alcohol (1: 1) accounts for mix monomer, initiator amount is 0.4% of a mix monomer, and buffer reagent sodium bicarbonate consumption is 0.5% of a mix monomer amount.In order to reduce product cost, guarantee the quality of product, to increase economic efficiency, the amount of butyl acrylate accounts for 50% of mix monomer, and vinylformic acid, N hydroxymethyl acrylamide consumption respectively account for 5% of mix monomer.Vinyl acetate between to for plastic, staybelite and glyceryl ester consumption thereof respectively account for 20% of mix monomer, and the emulsifying agent consumption is 0.6% of a mix monomer, and initiator, buffer reagent consumption are 0.5% of mix monomer amount respectively, and the amount that adds entry in the mix monomer is suitable with it.
The adhesive tape that the acrylate pressure sensitive adhesive modified by hydrogenated rosin stick is made is a mensuration through sending National Defence Science and Technology Univ. PLA five, its stripping strength, record 180 ° of stripping strengths and be up to 239 minutes and 20 seconds with hanging heavy method (2.1 * 12.9 centimetres of special-purpose kraft paper are hung heavy 227 grams), 90 ° are held sticking is 55 minutes 19 seconds (for details see attached table 1); Think through sending units such as Hunan Province Chemical Factory of Daily Use to try out: this product is pasted firmly, and adhesivity is stronger, and obscission does not chap; It is not only strong, easy to use to clean strawboard, fluting board cohesive force, can be used as soap, toothpaste, washing powder the outsourcing carton seal paper slip, and glass, pottery, plastic or other material vessel surface are also had stronger cohesive force.As if being printed as self-adhesive paper label, trade mark on the blank sheet of paper that this pressure-sensitive adhesive is coated on certain intensity, stickup then can be accomplished not only attractive in appearance but also convenient on solid surface.The acrylate pressure sensitive adhesive modified by hydrogenated rosin stick not only has performances such as good weather-proof, heat-resisting, the resistance to oxidation of acrylic acid or the like jelly, anti-solvent equally, and staybelite aboundresources, the pressure sensitive adhesive characteristic that adds staybelite is stable, cost is low, product hold viscosity, stripping strength all meets or exceeds domestic and international colleague's product.The adding of staybelite has reduced the consumption of esters of acrylic acid, has improved the economic benefit of product, the new purposes of having opened up staybelite.
