Abstract
The invention relates to a bonding agent for a label. The bonding agent is prepared from the following raw material ingredients in percentage by weight: 95 to 98 percent of base materials, 1 to 3 percent of curing agents and 0.3 to 0.4 percent of anti-aging agents, wherein the base materials comprise the following ingredients including 18 to 23 percent of butyl acrylate (BA), 4 to 8 percent of methyl acrylate (MA), 1 to 2 percent of butyl methacrylate (nBMA), 0.001 to 0.01 percent of acrylic acid (AA), 1 to 2 percent of 2-ethylhexyl acrylate (2-EHA), 0.1 to 0.5 percent of initiators and 64 to 75 percent of solvents. The bonding agent has the characteristics that the initial adhesion force is high; the curing speed is high; the label cannot fall off after being instantly pressed; the slippage and the tilting cannot occur; the holding adhesive power is realized; good bonding performance can be realized on most packaging materials, and the like. The use is very convenient, and better anti-aging performance is realized.
Description
Technical field
The invention belongs to adhesive area, particularly a kind of tackiness agent for label.
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 label, it is high that invention adhesive has initial bonding strength, curing speed is fast, label does not come off after exerting pressure instantaneously, not slippage, not warpage, hold tack, most wrapping material are had to the features such as good adhesiveproperties, be easy to use, and there is good ageing-resistant performance.
A kind of tackiness agent for label of the present invention, it is characterized in that: described tackiness agent, by weight percentage, material component comprises: base-material 95-98%, and solidifying agent is 1-3%, anti-aging agent 0.3-0.4%;
Wherein base ingredient is: butyl acrylate BA18-23% by weight percentage, methyl acrylate MA4-8%, butyl methacrylate nBMA1-2%, vinylformic acid AA0.001-0.01%, 2-EHA 2-HEA1-2%, initiator 0.1-0.5%, solvent 64-75%.
Described initiator is dibenzoyl peroxide BPO.
Described solvent is one or both in vinyl acetic monomer EtAc, toluene.
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 anti-aging agent is the one in antioxidant A T, antioxidant D, antioxidant A.
Described base ingredient is: butyl acrylate BA21.242%, methyl acrylate MA6.069%, butyl methacrylate nBMA1.517%, vinylformic acid AA0.008%, 2-EHA 2-HEA1.517%, initiator 0.284%, solvent 69.363%.
Described base ingredient is: butyl acrylate BA19.142%, methyl acrylate MA5.069%, butyl methacrylate nBMA1.617%, vinylformic acid AA0.005%, 2-EHA 2-HEA1.817%, initiator 0.294%, solvent 72.056%.
Described base ingredient is: butyl acrylate BA18%, methyl acrylate MA8%, butyl methacrylate nBMA1.59%, vinylformic acid AA0.001%, 2-EHA 2-HEA1.45%, initiator 0.16%, solvent 70.88%.
More tackiness agent of BA are harder, and the BA system of strong binding type sizing agent is more, although initial stage clinging power is not too high, As time goes on can increase.
NBMA is methacrylate-based monomer, and its effect can alleviate when using BPO series initiators the reaction that overlaps.The occasion that the initial stage addition of general BPO is more, initial reaction is very large, if but there is methacrylate-based monomer and acrylic ester monomer simultaneously, according to reactive size ratio, methacrylate-based monomer comparatively acrylic ester monomer first carries out polyreaction, and the polymerization reaction heat of the polyreaction ratio of specific heat acrylic ester monomer of methacrylate-based monomer is little, therefore initial stage heating is gentleer.
The occasion that MA uses many, the hardness of its tackiness agent is larger, and its cohesive force is also better, in the tackiness agent of label.
beneficial effect
Tackiness agent prepared by the present invention can be used as label type tackiness agent, it is high that invention adhesive has initial bonding strength, curing speed is fast, label does not come off after exerting pressure instantaneously, not slippage, not warpage, hold tack, most wrapping material are had to the features such as good adhesiveproperties, be easy to use, and there is good ageing-resistant performance.
