Abstract
The invention belongs to the technical field of adhesive chemical engineering, and particularly relates to a PE adhesive used for crown cover polyolefin gaskets of beers or beverages. The adhesive comprises the following components in percentage by weight: 60-70% of high-performance saturated polyester resin, 5-15% of polyurethane resin, 1-5% of polymethylene wax superfines, 0.05-0.1% of flatting agent, 0.05-0.2% of defoamer and 20-30% of solvent. The invention further discloses a method for preparing the PE adhesive. The method comprises the following steps of (1) weighing the high-performance saturated polyester resin, the aliphatic-blocked isocyanate resin, the defoamer and the solvent according to the weight parts and adding the above materials into a scoring cylinder, and dispersing for 10-15 minutes at a rotation speed of 500-800 r/min; (2) adding the polymethylene wax superfines weighed according to the weight parts slowly into the mixed solution obtained in the step (1), increasing the rotation speed to 1200-1500 r/min after the polymethylene wax superfines are completely added, and dispersing for 15-20 minutes to disperse the polymethylene wax superfines completely; (3) reducing the rotation speed to 500-800 r/min, adding the solvent and the flatting agent weighed according to the weight parts, dispersing for 15-20 minutes continuously, and mixing uniformly.
Description
Technical field
The invention belongs to field of chemical engineering of adhesives, particularly relate to crown cap polyolefin gasket PE tackiness agents such as a kind of beer, beverage and preparation method thereof.
Background technology
Metal Crown Lid is tinplate for glass bottle beer, white wine and carbonated drink etc. or ferrochrome bottle cap, and cover inside is made up of a coating film and pad, and this film is commonly called as tackiness agent.Gasket material major part is PE (polyolefine) material, and seldom part is PVC material, and PVC pad is due to market of fading out gradually containing harmful composition, therefore the pad of PE material becomes main flow gradually.The PE tackiness agent overwhelming majority used is epoxy phenolics system in the market, containing dihydroxyphenyl propane composition in this kind of tackiness agent, harmful.Along with people are to the lifting gradually of food-safety problem attention degree, research and development replace the above-mentioned adhesive product containing objectionable constituent and seem particularly important.
The following defect of current epoxy novolac class imperial crown PE lid tackiness agent ubiquity: rustless property can not meet the more and more stricter requirement of bottle cap producer; Use epoxy resin in raw material, also have problems in strict food safety.
Summary of the invention
The present invention provides a kind of adhesiveproperties, snappiness and high rust resistance and human body is not produced to the Metal Crown Lid PE tackiness agent of injury for solving in known technology the technical problem that exists.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of Metal Crown Lid PE tackiness agent comprises following component according to weight percent meter, high-performance saturated polyester resin 60-70%, urethane resin 5-15%, polyethylene micropowder wax 1-5%, flow agent 0.05-0.1%, defoamer 0.05-0.2%, solvent 20-30%.
Preferably: Metal Crown Lid PE tackiness agent comprises following component according to weight percent meter, high-performance saturated polyester resin 65%, aliphatics blocked isocyanate resin 8%, polyethylene micropowder wax 5%, flow agent 0.05%, defoamer 0.1%, solvent 21.85%.
Preferably: described flow agent is chosen for fluorin modified crylic acid ester flow agent.
Preferably: described defoamer is chosen for not containing organosilicon polymer defoamer.
Preferably: described solvent be chosen in DBE and S-150 one or both.
Another object of the present invention is to provide a kind of method preparing above-mentioned PE tackiness agent, comprise the following steps: (1) takes high-performance saturated polyester resin, aliphatics blocked isocyanate resin, defoamer and solvent according to weight part and adds successively in scuffing of cylinder bore, under 500-800r/min rotating speed, disperse 10-15min; (2) slowly add the polyethylene micropowder wax weighed according to weight part in the mixing solutions obtained to step (1), after adding completely, improve rotating speed to 1200-1500r/min, dispersion 15-20min, fully disperses polyethylene micropowder wax; (3) reduction of speed is to 500-800r/min, adds the flow agent and solvent that weigh according to weight part, continues dispersion 15-20min, mixes.
Advantage of the present invention and positively effect are: common epoxy novolac formula system abandoned by Metal Crown Lid PE tackiness agent of the present invention, develop brand-new polyester formulation system, this product containing dihydroxyphenyl propane and softening agent, does not injure human body, can meet the requirement of food safety.Detect through third party feeler mechanism, indices is all far below the limitation of the maximum migration amount of national relevant food hygienic standard regulation.Product performance have surmounted a large amount of epoxy novolac class Metal Crown Lid PE tackiness agent used now, have and PE (polyolefine) gasket material.
Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Metal Crown Lid PE tackiness agent of the present invention comprises following component according to weight percent meter, high-performance saturated polyester resin 60-70%, urethane resin 5-15%, polyethylene micropowder wax 1-5%, flow agent 0.05-0.1%, defoamer 0.05-0.2%, solvent 20-30%.
Further, comprise following component according to weight percent meter, high-performance saturated polyester resin 65%, aliphatics blocked isocyanate resin 8%, polyethylene micropowder wax 5%, flow agent 0.05%, defoamer 0.1%, solvent 21.85%.
Wherein, flow agent is chosen for fluorin modified crylic acid ester flow agent; Defoamer is chosen for not containing organosilicon polymer defoamer; Solvent be chosen in DBE and S-150 one or both.DBE defines: high boiling solvent mixed dibasic acid ester (Du Pont claims DBE) is diester mixture, also known as dibasic ester; S-150 is aromatic solvent.
