Abstract
The invention belongs to adhesive field, have three types to be the medical acrylate emulsion pressure-sensitive, protective membrane acrylic ester emulsion pressure sensitive adhesive and the bonding acrylic ester emulsion glue of using.Advantages such as the medical acrylate emulsion pressure-sensitive is a cross-linked type pressure sensitive glue, has the force of cohesion height, and fast viscous force is moderate.It is low that protective membrane has a fast viscous force with the acrylic ester emulsion pressure sensitive adhesive, and peeling force is little, and the force of cohesion advantages of higher can be made into the protective membrane of various base materials, and protection metal, synthetic glass, various vessel, instrument etc. are not scratched it.
Tackiness agent also can be used for mutual bonding etc. of paper, fiber, plastics.
Description
The invention belongs to adhesive field.The present invention has three types, i.e. medical acrylate emulsion pressure-sensitive, and protective membrane is with acrylic ester emulsion pressure sensitive adhesive and the bonding acrylic ester emulsion glue of using.
In the prior art; there be not to find the technology identical through consulting pertinent data with foregoing invention; domestic compound tackiness agent and the protective membrane tackiness agent used of paper of once producing; but contain organic solvents such as acetone, capryl acetate in its prescription; therefore this product poisonous, inflammable, contaminate environment, waste energy, be national limit production.
Purpose of the present invention just is to solve domestic urgent need, production New Emulsion glue.
Three kinds of emulsion glue of the present invention all contain Acrylic Acid Monomer, emulsifying agent, initiator, pH regulator agent, deionized water etc.
Concrete prescription and technology are as follows:
1, medical acrylate emulsion pressure-sensitive prescription sees Table 1(unit: gram)
Technical process is as follows:
Deionized water and emulsifying agent op-4, oS-15, sodium lauryl sulphate are added in the polymeric kettle, and normal temperature emulsification one hour adds three kinds of monomers such as 2-EHA, vinylformic acid and vinyl acetate and mixes 1/10th of back total amount.Initiator potassium persulfate 3/4ths in reactor, begin to heat up, rose to 80 ± 2 ℃ in 30 minutes, be incubated after 15 minutes, drip surplus monomer and initiator potassium persulfate, evenly drip off with 2-3 hour, be incubated 15 minutes again, be warmed up to 85-87 ℃, be incubated 30 minutes again, be cooled to 40 ℃ of blowings.
Have only three kinds of monomers in this prescription, i.e. soft monomer one 2-EHA, hard monomer-vinyl acetate, reactive monomer-vinylformic acid is formed, and makes simplified control.
Added trimeric cyanamide in this prescription, in letex polymerization, made the part linear structure become half cancellated polymkeric substance, force of cohesion is improved.
2, protective membrane sees Table 2(unit with the prescription of acrylic ester emulsion pressure sensitive adhesive: gram)
Its technology is identical with the medical acrylate emulsion pressure-sensitive, and different is has increased monomer ， And such as butyl acrylate and methyl esters and other monomer adds simultaneously in the composition.Emulsifying agent replaces oS-15 with op-10.
3, bondingly see Table 3(unit: gram) with acrylic ester emulsion glue prescription
Its technology is also identical with the medical acrylate emulsion pressure-sensitive.Replaced vinylformic acid and 2-EHA monomer with N hydroxymethyl acrylamide and ethyl propenoate in different the is prescription, used MS-1 to replace oS-15 in the emulsifying agent and used the chain terminator lauryl mercaptan.Owing to added N hydroxymethyl acrylamide, make the present invention be coated with heating back linear structure and partly become reticulated structure, can solidify voluntarily, owing to added lauryl mercaptan, controlled the molecule aggregation degree within the specific limits simultaneously.
By above-mentioned processing method, embodiment 1 proportioning of getting respectively in table 1, table 2, the table 3 is carried out technological operation, all can obtain satisfied product.
Advantages such as medical acrylate emulsion pressure-sensitive and cross-linked type pressure sensitive glue have the force of cohesion height, and fast viscous force is moderate, it can replace zinc oxide adhesive plaster.
It is low that protective membrane has a fast viscous force with the acrylic ester emulsion pressure sensitive adhesive, and peeling force is little, and the force of cohesion advantages of higher can be made into the protective membrane, protection metal, synthetic glass, various vessel, instrument of various base materials etc., and it is not scratched.
