Abstract
The invention relates to an adhesive for stripping adhesive tape. The adhesive is prepared from a base material and a curing agent with the mass ratio of (95-98):(2-5). The base material is prepared from, by weight, 28%-35% of acrylic acid 2-ethylhexyl acrylate 2 (EHA), 0.08%-0.2% of methyl acrylate (MA), 0.5%-2% of vinyl acetate (VAC), 50%-73% of solvent and 0.1%-0.3% of initiator. The adhesive is good in stripping performance, and has the advantages of being capable of being stripped, free of an adhering phenomenon, resistant to abrasion, free of adhesive residue and low in tension. The adhesive for stripping the adhesive tape is good in bonding performance, high in strength and not likely to be broken in the stripping process.
Description
Technical field
The invention belongs to adhesive area, particularly a kind of tackiness agent for stripping tape.
Background technology
Glued joint (bonding, bonding, cementing, gluing) and refer to the technology that homogeneity or heterogeneous body surface stick with glue agent and link together to there is stress distribution continuous, lightweight, or sealing, the features such as most technological temperature is low.Glued joint the connection being specially adapted to unlike material, different thickness, ultra-thin specification and complex component.Glued joint RECENT DEVELOPMENTS the fastest, application industry is extremely wide, and has great effect to high-and-new science and technology progress and people's daily life improvement.Therefore, study, all kinds of tackiness agent of development and production is very important.
Along with going from bad to worse of global environment, people bring into use some environmentfriendly products gradually.Although tackiness agent is not really the huge Chemicals of a class, the harm of environment also be can not be ignored.The tackiness agent of those non-environment-friendly types will be abandoned gradually.Polyvinyl formal tackiness agent (being commonly called as " 107 glue "), due to containing free formaldehyde, is detrimental to health.Forbid already in developed country, but in China because it is cheap, so still have the suitable market share.But its consumption reduces gradually, will all eliminate soon.How to make the tackiness agent of non-environment-friendly type become environmental-protection type adhesive by modification is imperative work.A kind of tackiness agent replaced not containing formaldehyde in plywood making has been studied successfully by Japanese firm.Common urea formaldehyde and melamine tackiness agent contain the formaldehyde that human allergy can be caused to react, and intensity, the water tolerance of this tackiness agent are close with melamine tackiness agent with cost.In today that the cry of environmental protection grows to even greater heights, increasing people starts the development being devoted to biodegradable tackiness agent.The biological degradation of polymkeric substance has been come by hydrolysis and oxygenizement.The polymkeric substance that major part can be degraded contains degradable group, such as amido, hydroxyl, urea groups etc. on its main chain.React with two hydroxyl and ether, the polyester of synthesis containing methylol, as matrix, produces biodegradable tackiness agent, and they are also with containing the butyric ester, valerate, Mierocrystalline cellulose, starch ester etc. of hydroxyl as matrix, with sucrose ester as tackifier, produce the tackiness agent of energy biological degradation or hydrolysis.In addition, with starch or sulfonated ester for matrix, add the wax containing polarity, produce containing polarity, to the tackiness agent of water sensitive, unboiled water solution can be issued in the effect of water, reduction or the pollution eliminated environment when carrying out waste treatment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of tackiness agent for stripping tape, and separability of the present invention is good, has peelable without adherent phenomenon, abrasion-resistant, not cull, the feature that pulling force is light; The cohesiveness of stripping tape of the present invention is good, and intensity is high, and stripping process is not easy fracture.
A kind of tackiness agent for stripping tape of the present invention, by weight percentage, mass ratio is base-material and the solidifying agent of 95-98:2-5;
Wherein base-material component: be by weight percentage: 2-EHA 2EHA28-35%, methyl acrylate MA0.08-0.2%, vinyl acetate VAC0.5-2%; Solvent 50-73%, initiator 0.1-0.3%.
Described solvent is one or more in vinyl acetic monomer, toluene.
Vinyl acetic monomer and the toluene of described solvent to be mass ratio be 2 ~ 1:1.
Described initiator is Diisopropyl azodicarboxylate AIBN.
Described solidifying agent is isocyanates solidifying agent.
Described isocyanates solidifying agent is tolylene diisocyanate, diphenylmethanediisocyanate, isophorone diisocyanate, 1, hexamethylene-diisocyanate, 1, one or more in 5-naphthalene diisocyanate, trimethylammonium 1,6-hexamethylene diisocyanate.
Described base ingredient is: 2-EHA 2EHA28.856%, methyl acrylate MA0.08%, vinyl acetate VAC0.563%; Solvent 70.342%, initiator 0.159%.
Described base ingredient is: 2-EHA 2EHA30.542%, methyl acrylate MA0.18%, vinyl acetate VAC1.50%; Solvent 67.528%, initiator 0.250%.
Described base ingredient is: 2-EHA 2EHA35%, methyl acrylate MA0.15%, vinyl acetate VAC1%; Solvent 63.694%, initiator 0.156%.
Vinylformic acid AA's is more, and its tackiness agent polarity is higher, and firmly to also larger, thermotolerance is better, and clinging power is also higher, on the contrary, the occasion that AA consumption is few, its tackiness agent polarity is low, and flexibility is good, and clinging power also reduces; AA with few occasion, its tackiness agent hardness is little, and cohesive force is low, i.e. its confining force or determine the reductions such as loading performance.
When 2EHA consumption is more, although its initial stage clinging power improves, As time goes on can reduces, be applicable to the making of exfoliated adhesive tape.
VAC monomer, hardly for initial stage polyreaction, is generally used for later stage interpolation, mainly plays the effect of less residual monomers.
beneficial effect
Separability of the present invention is good, has peelable without adherent phenomenon, abrasion-resistant, not cull, the feature that pulling force is light;
The cohesiveness of stripping tape of the present invention is good, and intensity is high, and stripping process is not easy fracture.
