Description
Technical field
The present invention relates to a kind of contact adhesive composition, it is not subjected to the influence of plasticizer migration in the substrate, thereby keeps competent viscosity on the substrate of plasticizer-containing.
Background technology
Soft PVC (PVC) film is cheap, and the polyvinyl chloride rubber belt that obtains behind the coating pressure sensitive adhesive can be widely used in the decoration of door and window, metope, furniture and outdoor advertising etc.
The preparation of soft PVC film is to add softening agent in polyvinyl chloride (PVC) RESINS, and it is slided between the polyvinyl chloride chain molecule, enlarges distance between molecular chain, reduces gravitation between molecular chain, thereby reaches the softening purpose of plasticising.Softening agent generally is meant the plasticity-and the flowability that can increase plastics, rubber when machine-shaping and makes finished product have flexible organic substance.Owing to mix the sheerly physical process of softening agent with polyvinyl chloride (PVC) RESINS, between the usage period, softening agent (especially monomer-plasticizer) has the tendency to the polymer surfaces migration in various degree at film.For example, dimixo-octyl phthalate (DOP) often is used as softening agent at home and is widely used in the soft advertisement cloth of manufacturing.If on this advertisement cloth by pressure sensitive adhesive bonding decorative adhesive film, then because this softening agent bring potential hazard can for the performance of pressure sensitive adhesive to the migration on soft advertisement cloth surface.In order to prevent that softening agent from causing pressure sensitive adhesive viscosity to descend to surface transport, prior art is improved the composition of pressure sensitive adhesive or the structure of finished product.
U.S. Pat 4,284,681 and US 4,045,600 proposed between pressure sensitive adhesive and polyvinyl chloride soft base material to introduce one deck screen layer.The problem that softening agent moves the pressure sensitive adhesive viscosity degradation that causes to substrate surface though this method has solved, this method can cause the concentration accumulation of plasticizer molecule between tackiness agent and base material, impair the bonding between the interface.
Another kind method is directly to add softening agent with the concentration gradient between the reduction contact layer in tackiness agent, and migration of plasticizer in the inhibition base material (referring to European patent EP 150978A, EP 593231A, U.S. Pat 4,272,573, US 4,946, and 742, US 5,049,608, US 5,500,293).
U.S. Pat 5,800,919 have disclosed the plasticizer-resistant transport property of not only having improved tackiness agent by the interpolation softening agent, and the superiority of giving tackiness agent self low-temperature construction.But the limitation part of this method is: the softening agent that adds in the tackiness agent must be identical with the used softening agent of PVC base material, can prove effective.Otherwise still exist the concentration gradient of softening agent, cause the glue face migration of softening agent, finally damage the bonding strength of pressure-sensitive adhesive to lower concentration.
The third method is to adopt copolymerization process to introduce nitrogenous in the pressure sensitive adhesive preparation process or contain the polar structure unit of carbonyl, as vinylformic acid, vinyl cyanide, acrylamide, N-vinyl pyridine, N-vinyl pyrrolidone etc. (referring to U.S. Pat 4,364,972, US 4,605,592, US 4,946,742, US 5,019,377, US5,861,211, European patent EP 615983A2).This method defective is the manufacturing process complexity, and prepared tackiness agent tack is lower.
In order to improve the tack of pressure sensitive adhesive, U.S. Pat 4,943,461 have proposed a kind of photopolymerizable pressure sensitive adhesive, and it comprises acrylic copolymer, paracril, light trigger and the optional linking agent that is formed by vinylformic acid non-uncle's alkane ester and the nitrogenous vinyl monomer of polarity.Though this pressure sensitive adhesive has good anti-plasticizer migration, it must use the expensive acrylic copolymer with polarity nitrogen containing monomer and need to use expensive ultraviolet light polymerization equipment.
The water-based latex type caking agent that the clear 53-57239 of day disclosure special permission communique has proposed to utilize nitrile group content to make as tackifying resin and polyacrylate blending latex for the nitrile rubber of 15-40% (mol ratio).Though improve the plasticizer-resistant characteristic of double-faced pressure-sensitive glued membrane, but the emulsifying agent in the latex can make the water tolerance variation of pressure sensitive adhesive, unsuitable outdoor life-time service.
Therefore, also need a kind of contact adhesive composition, it need not to use the expensive acrylic copolymer with polarity nitrogen containing monomer or uses expensive ultraviolet light polymerization equipment, thereby can reduce the manufacturing cost of product, in addition, require this composition to need not to use emulsifying agent, thereby improve the weather resistance of outdoor use.
