Abstract
The invention relates to an adhesive used for a protecting film. The adhesive comprises raw material components as follows: a base material and a curing agent in the mass ratio being (95-98): (2-5), wherein the base material comprises components as follows: 28%-35% of BA (butyl acrylate), 0.5%-2% of AA (acrylic acid), 0.5%-2% of VAC (vinyl acetate), 40%-60% of a solvent, 0.05%-0.5% of an initiator and 8%-15% of tackifying resin. The adhesive has the advantages of high viscosity, no bubbling, low probability of shedding, high cohesion force of an adhesive film, high transparency and no degumming, has better weather fastness and is environment-friendly and pollution-free, and no residues are reserved on a substrate.
Description
Technical field
The invention belongs to adhesive area, particularly a kind of tackiness agent for the protection of film.
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.

More tackiness agent of BA are harder.
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.
AA is monomer; its mainly with-COOH for functional group and its bridging action of stiffening agent; its tackiness agent of many occasions of AA and the clinging power of metal sheet increase; but part AA tackiness agent can be made hardening; feel is deteriorated; AA consumption solvent resistance of many times, petrol-resistance are all better, therefore generally in protective membrane adhesive tape, use the tackiness agent that AA consumption is many.
VAC monomer, hardly for initial stage polyreaction, is generally used for later stage interpolation, mainly plays the effect of less residual monomers.
