Description
Technical Field
The invention relates to the field of cleaning agents, and particularly relates to a cleaning agent capable of sufficiently removing residual hot melt adhesive of a gluing device and polyurethane condensate which is difficult to remove in the application process of reactive Polyurethane (PUR) hot melt adhesive.
Background
Reactive polyurethane hot melts are a class of adhesives that are solvent-free and that exhibit a solid form at room temperature. The adhesive strength of the reactive polyurethane hot melt adhesive is different from that of the common hot melt adhesive, the reactive polyurethane hot melt adhesive contains isocyanate-terminated (NCO) polyurethane prepolymer, and the isocyanate-terminated (NCO) polyurethane prepolymer can react with moisture or active hydrogen substances in the air or on an adherend to form a partially crosslinked reticular structure, so that the adhesive strength, chemical resistance, heat resistance, hydrolysis resistance and other properties of the reactive polyurethane hot melt adhesive are superior to those of the common hot melt adhesive. Meanwhile, the polyurethane adhesive has the thermoplastic cold setting property of common hot melt adhesive, is simple and convenient to bond, and has the characteristics of wide range of adherends, large performance adjustability, good surface compatibility on paint surfaces and the like, and the like. The PUR hot melt adhesive has the characteristics of 100% solid content, no solvent, environmental protection and the like, and enters various new application fields along with the continuous development of the technology, so that the share of the PUR hot melt adhesive in the adhesive industry is increased, meanwhile, the sizing equipment of the PUR hot melt adhesive is gradually developed towards the diversification direction, and the thorough cleaning of the sizing equipment becomes a more prominent problem.
Generally, the known reactive polyurethane hot melt adhesive cleaning agent is mainly formed by mixing ethylene-vinyl acetate copolymer (EVA) with other resins, and the system is not well compatible with common PUR hot melt adhesives, but removes residual adhesives by mixing, diluting and transferring with the PUR hot melt adhesives. However, since the PUR hot melt adhesive has functional reactive group NCO, once the reactive group NCO is cross-linked and cured due to misoperation, improper control of environmental humidity, untimely cleaning after glue application, and the like during the use of the hot melt adhesive, infusible precipitates which are difficult to remove are generated at various positions of pipelines, rollers and the like of a glue application device, so that the glue application points of the pipelines, the rollers and the like are blocked. The common reactive polyurethane hot melt adhesive cleaning agent can not effectively clean the polyurethane condensate, and customers have to clean the polyurethane condensate in a mode of scraping, sanding, even burning at high temperature and the like which are complicated in operation and can damage the service life of equipment.
The prior Chinese patent CN102719325A discloses a novel reactive polyurethane hot melt adhesive cleaning agent; the product of the patent can thoroughly neutralize the residual NCO in the PUR hot melt adhesive, inhibit the further reaction of the functional reaction group NCO in the reactive PUR adhesive, and ensure that no polyurethane condensate can appear in the cleaning process. However, for the existing polyurethane condensate, the product of the patent does not have the treatment capacity as the common reactive polyurethane hot melt adhesive cleaning agent on the market, but the polyurethane condensate does not only appear in the cleaning process, and NCO groups can be crosslinked and cured at any time in the environment with proper humidity, so that once the conditions of misoperation, improper control of environmental humidity, untimely cleaning after glue application and the like occur in the use process of the hot melt adhesive, the polyurethane condensate can be rapidly generated in pipelines, rollers and the like of gluing equipment.
Therefore, the development of a cleaning agent capable of fully removing residual hot melt adhesive of gluing equipment and polyurethane condensate which is difficult to remove in the application process of reactive Polyurethane (PUR) hot melt adhesive solves the difficult problems in the actual cleaning process, and has great significance for hot melt adhesive enterprises and downstream customers such as automobiles, textiles, wood, electronics and other industries.
Disclosure of Invention
Therefore, the invention provides a novel reactive polyurethane hot melt adhesive cleaning agent, which aims to solve the problems that the existing reactive polyurethane hot melt adhesive cleaning agent is difficult to treat infusible precipitates generated by curing and crosslinking of reactive polyurethane hot melt adhesive, so that equipment pipelines and roller gluing points are easy to block, and the cleaning agent has to be cleaned in a mode of scraping, sanding, even high-temperature firing and the like, which are complicated in operation and can damage the service life of equipment.
Except that the long-chain fatty alcohol in the formula can also play a role in inhibiting NCO group crosslinking and curing in the cleaning process, when the reactive polyurethane hot melt adhesive residual adhesive is cleaned, the polar organic solvent in the formula can effectively penetrate through the surface layer of a cured product and firstly cracks a polyurethane polymer chain, so that other components in the formula are allowed to penetrate into the core of the cured product. The chemical structure of the polyether surfactant in the formula is similar to that of the soft segment of the polyurethane polyether, and the contact and penetration of the cleaning agent component and a single polyurethane polymer chain are facilitated.
After the cleaning agent breaks the cured skin and penetrates the core sufficiently, the combination of polyether surfactant, methyl oleate and terpene compounds can initiate swelling of the polymer matrix, provide a greater contact area between the polar solvent and the polymer chains, and further lead to polymer chain scission. The generated low molecular weight cracking products are dissolved/rinsed by the cleaning agent from the polymer matrix batch by batch under the solubilization/emulsification action of the surfactant, and finally the purpose of completely removing the polyurethane cured product is achieved.
In order to achieve the above purpose, the invention provides the following technical scheme:
the novel reactive polyurethane hot melt adhesive cleaning agent provided by the invention comprises 10-30% of ethylene-vinyl acetate copolymer, 1-10% of tackifying resin, 20-70% of long-chain fatty alcohol, 5-20% of polar organic solvent, 2-10% of polyether surfactant, 1-5% of methyl oleate, 1-5% of terpene compound, 1-5% of plasticizer and 0.1-1% of antioxidant.

Further, the long-chain fatty alcohol is one or more of hexadecanol, heptadecanol and octadecanol; by way of example, the preferred range of long chain fatty alcohols is 30% to 60%. Hydroxyl in the long-chain fatty alcohol can neutralize the residual NCO end in the PUR hot melt adhesive, so that the effect of the long-chain fatty alcohol in the formula is used for completely neutralizing the residual NCO end in the PUR hot melt adhesive besides being used as a solvent to participate in the dissolution and rinsing of low-molecular-weight cracking products, and the generation of new polyurethane condensate in the cleaning process is avoided.
Further, the polar organic solvent includes one or more N-substituted pyrrolidones including, but not limited to, one or more of N-methylpyrrolidone, N-ethylpyrrolidone, N-hydroxyethylpyrrolidone, N-propylpyrrolidone, N-phenylpyrrolidone, N-benzylpyrrolidone, N-cyclohexylpyrrolidone, and N-octylpyrrolidone, with a preferred range of 10% to 20% being exemplified.
