Description
Technical field
The present invention relates to a kind of beer, beverage bottle cap gasket adhesive specially and preparation method thereof, belong to field of chemical engineering of adhesives.
Background technology
Beer, beverage bottle cap are made up of three parts, iron cap, pad, sizing agent.Iron sheet is tinplate or chromium plating iron, and Bottle cap spacer is modified polyethylene material.The manufacture method of this bottle cap is generally such: first by sizing agent dissolution homogeneity scrubbing brush on iron sheet, then iron sheet is sent into far-infrared heating case heating (150 ~ 180 DEG C), in this process, the solvent evaporates in sizing agent, sizing agent Procuring; Then this iron sheet stamping machine is gone out iron cap, then the gasket material of melting is filled on iron covering; Finally will be added with the iron covering stamping forming of the gasket material of melting, beer, beverage cap for special purpose can be obtained.
At present, the technology of this tackiness agent, existing patent, be tackiness agent of pad and preparation method thereof as Chinese patent CN101503606A mentions a kind of polyolefine material: first epoxy resin 609 is joined in mixing tank with solvent and mix, then joined in the reactor with backflow, division box, stir under 100 ~ 140 DEG C of conditions, heat, be incubated, reflux, divide water, keep 3-4h to dissolve completely to epoxy resin, be cooled to 40 ~ 60 DEG C of filtrations and make epoxy resin solution A; The epoxy resin solution A prepared and epoxy resin E-51, polyethylene wax dispersion, tinting material, solidifying agent are joined in reactor successively in proportion, temperature of charge keeps 30 ~ 45 DEG C, abundant stirring 40 ~ 60min mixes rear filtration, obtained finished product after being cooled to room temperature.
In use come with some shortcomings with the sizing agent that the method is made.First the cohesive strength being this sizing agent is not high, and 180
°stripping strength is at 1.0 ~ 2.0KN/m(GB/T 2790-1995); Secondly, easily there is be full of cracks after hardening in sizing agent.
In addition, the method complex process, energy consumption are high.Owing to containing a certain amount of moisture in epoxy resin 609, and bad with all the other component compatibilities in sizing agent.So, need when adopting epoxy resin 609 to manufacture sizing agent to adopt the steps such as stirring, heating, insulation, backflow, point water.This just increases the complicacy of technique virtually, increases energy consumption.
Summary of the invention
According to the deficiencies in the prior art, the technical problem to be solved in the present invention is: provide a kind of beer, beverage bottle cap gasket adhesive specially and preparation method thereof, and firmly, good seal performance, energy consumption is low for bonding.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of beer, beverage bottle cap gasket adhesive specially and preparation method thereof, it is characterized in that being prepared from by the following raw material with weight parts:
Described epoxy resin is the raw material liquid diglycidyl ether type epoxy resin obtained through polycondensation by polyphenol or polyvalent alcohol and epoxy chloropropane, and it is a kind of, two or more the mixture wherein such as bisphenol A diglycidyl ether, Bisphenol F diglycidylether or bisphenol-S diglycidyl ether.
In described ethylene-vinyl acetate copolymer, vinyl acetate content is 5-50%, preferred 28-42%; Mooney viscosity MI:5-200, preferred mooney viscosity MI:20-150.
Described mixed solvent is two kinds or two or more mixtures of aromatic hydrocarbon, alcohols, ester class, ketone, and in this mixed solvent, the content of aromatic hydrocarbon is more than or equal to 45% of solvent total mass.
Described solidifying agent is acid anhydrides or amidourethane or both mixtures.
Described initiator is one or more the mixture in BP, dicumyl peroxide or dicumyl peroxide etc.
Described linking agent is the mixture of the one or more than one in 1,2-Vinylstyrene, allyl methacrylate(AMA) or allyl acrylate.
Described oxidation inhibitor is the mixture of the one or more than one in 1010,168 or 1076.
Described softening agent is the mixture of the one or more than one in epoxy soybean oil, epoxy aliphatic acid methyl ester, diethylene glycol dibenzoate, triethyl citrate or ATBC.
Described mineral filler is the mixture of a kind of in aerosil or wilkinite or two kinds.
Under normal circumstances, epoxy resin adhesive and metal have stronger cohesive force, but not high with intensity during polyethylene bonding.Tracing it to its cause, is because the molecular structure similarity gap of polyethylene and epoxy resin causes greatly.Polyethylene has very high degree of crystallinity, non-polar group in molecular structure, and apparent activation energy is very low, and adsorptive power is very poor, and containing aerobic, chlorine etc. in epoxy molecule, has stronger polarity; The molecular structure similarity gap of the two is more far, and epoxy resin infiltrates polyethylene difficulty.So epoxy resin adhesive is easy after solidifying to come off from polythene material surface.This also just causes the cohesive strength of sizing agent not high.And after epoxy resin adhesive solidification easily be full of cracks be due to after epoxy resin cure, occur excessively crosslinked, and hardening, become fragile and cause, adding a small amount of softening agent can avoid.
Therefore, overcome above-mentioned defect, sizing agent merely uses epoxy resin to be more difficult, should consider that adding other composition carries out composite, obtains higher cohesive strength to sizing agent when boning polyethylene.
As everyone knows, EVA is a kind of thermoplastic resin by ethene and vinyl-acetic ester random polymerization, due to its molecular structure and polyethylene similarity very high, so it and polyethylene have excellent cementing property.But EVA molecule linearly structure, intermolecular force of cohesion is little, so the cohesive strength between the EVA resin of hot melt and hot-melt polyethylene is not high.If be cross-linked by EVA, the linear structure of molecule is become stereoscopic three-dimensional structure, intermolecular force of cohesion will significantly strengthen, and just likely obtains higher cohesive strength.
In order to obtain the sizing agent of high strength, EVA being dissolved in a solvent, adding linking agent and initiator, epoxy resin, epoxy curing agent, softening agent, antioxidant and other mineral filler, after sizing agent solidification, just can improve cohesive strength during bonding polythene material.Thus prepare the higher pad sizing agent of cohesive strength.
In the selection of auxiliary agent, under the prerequisite meeting intensity, manufacture and operation condition, first to consider nontoxic and wholesomeness.
Epoxy resin is the raw material liquid diglycidyl ether type epoxy resin obtained through polycondensation by polyphenol or polyvalent alcohol and epoxy chloropropane.Solidifying agent selects acid anhydrides and amidourethane.
The selection of EVA will take into account its solvability in a solvent and with poly handing-over.The performance of EVA decides primarily of VA (vinyl-acetic ester) wherein, when VA content resin flexible of many time is soft, fold resistance and stickiness strengthen, and solvability (as aromatic hydrocarbon, halohydrocarbon, ester class, ketone) in a solvent increases with VA content and increases.It and poly cementing property reduce.Otherwise when VA content reduces, resin hardens, solvability (as aromatic hydrocarbon, halohydrocarbon, ester class, ketone) in a solvent reduces, and it and poly cementing property strengthen.
Solvent should select the kind to EVA favorable solubility, also will consider its boiling point.Boiling point is too high, and during solidification, not volatile, boiling point is too low, during production, easily volatilizees, easily loses.
First add in reactor by EVA, mineral filler, mixed solvent, stir and heat up, temperature controls at 50 ~ 70 DEG C, after EVA dissolves completely, be cooled to less than 30 DEG C, add epoxy resin, solidifying agent, initiator, linking agent, softening agent, stir, filter, obtain required tackiness agent.
The invention has the beneficial effects as follows: provide a kind of bonding firmly, the beer of good seal performance, beverage tackiness agent of polyethylene pad and preparation method thereof, compared with prior art, the cohesive strength of the sizing agent made by this project approach significantly improves, and 180 ° of stripping strengths are at 3.0 ~ 5.0KN/m(GB/T 2790-1995); Secondly, effectively prevent the situation that chapping appears in sizing agent after hardening.In addition, because the present invention has lacked the step such as backflow, point water in process of production, manufacture method is easy, and energy consumption is low.Bottle cap producer can prepare at scene voluntarily, greatly can promote the competitive power of Domestic Beer, beverage bottle cap manufacturer.
