Description
Technical field
The present invention relates to the preparation of bottle cap sealing glue gasket, particularly to the preparation method of asepsis environment-protecting polycinyl chloride gasket seal in a kind of tinplate bottle cap.The inventive method is mainly used on bottled food seal bottle cap polyvinyl chloride sealant pad on tinplate bottle cap, belongs to Food Packaging technology field.
Background technology
Tinplate bottle cap is now widely used bottled seal bottle cap, bottle cap sealant is indispensable important materials when the sealing of bottled product, when using especially as bottled food seal bottle cap, requirement to bottle cap sealant is more and more higher, not only require good seal performance, but also require food and environmental nonpollution.Along with the development of science and technology, the whole world is more and more higher to the requirement of polycinyl chloride bottle cap sealant, does not require nothing more than good seal performance, but also requires food and environmental nonpollution.But, the phthalic ester plasticizer that traditional polrvinyl chloride PV C bottle cap sealant uses, owing to having been found to there is human liver certain detrimental effect, its use is restricted.PVC packing ring containing poisonous plasticizer and additive is the arch-criminal causing multiple homemade goods to be prohibited selling, so being badly in need of using new material, new technique, new process development novel environment friendly polycinyl chloride bottle cap sealant.The composition of polyvinyl chloride sealant, the preparation of fluid sealant and operating parameter are the principal elements affecting polyvinyl chloride sealant pad energy.Therefore, the research and development composition of polyvinyl chloride sealant, the preparing process of fluid sealant and optimize operating parameter and seem and be even more important.Therefore, need to develop one in a hurry and prepare a kind of to food and eco-friendly tinplate bottle cap sealant process.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of preparation technology is simple and convenient, preparation quality is good, good sealing effect, environmental protection, safety, to the preparation method of asepsis environment-protecting polycinyl chloride fluid sealant pad in food and eco-friendly tinplate bottle cap.
nullThe technical scheme realizing above-mentioned purpose is: the preparation method of asepsis environment-protecting polycinyl chloride fluid sealant pad in tinplate bottle cap，Including: 1) prepare sealed colloid，Calculate in parts by weight，It is equipped with PVC paste resin 80-120 part、P-phthalic acid dibutyl ester 30-60 part、Tributyl 2-acetylcitrate 15-35 part、Ground calcium carbonate 10-30 part、Calcium one zinc stabilizer 1.5-3.5 part、Poliosis infusion 0.8-1.6 part、Titanium dioxide O.5-l.1 part、Dimethicone 0.3-0.9 part and Oleum Brassicae campestris 2-4 part，Terephthaldehyde's base dibutyl ester and tributyl 2-acetylcitrate mix homogeneously are as plasticizer，Plasticizer is divided into three parts，Take a copy of it plasticizer，O.5-1.5 minute stir under the speed of 200-250 rev/min，Then the speed of 120-160 rev/min，Add poliosis infusion while stirring、Titanium dioxide、Calcium one zinc stabilizer、Ground calcium carbonate，Then under the speed of 800-900 rev/min, stir 15-25min，The speed of 120-160 rev/min，Add PVC paste resin while stirring，And it is gradually added another part of plasticizer，4-6min is stirred under 120-160 rev/min of speed，Add remaining a plasticizer，The speed of 700-750 rev/min、It is sequentially added into dimethicone and Oleum Brassicae campestris after the environment of 40 DEG C stirs 4-6min，After stirring 10-15min，Screen filtration through 120 mesh，It is prepared from sealed colloid；
2) injecting glue molding, the inner side of tinplate bottle cap is cleaned out, the sealed colloid that uniformly prepared by note step 1) on the inner seal circle face of tinplate bottle cap, form circle lamellar injecting glue, be asepsis environment-protecting polycinyl chloride fluid sealant pad in tinplate bottle cap by the injecting glue hot briquetting on tinplate bottle cap.
The degree of polymerization of described PVC paste resin is 1250.
Described poliosis infusion is sodium bicarbonate.
Described dimethyl-silicon oil viscosity is 60 mpa.s.
The granularity of described ground calcium carbonate is 1250 mesh.
The temperature of described hot briquetting is 180-220 DEG C.
In tinplate bottle cap, the temperature of injecting glue is 30 DEG C.
The thickness of described circle lamellar injecting glue is 1-3.
The simple science of the inventive method, in the tinplate bottle cap of preparation, asepsis environment-protecting polycinyl chloride seal gasket tablet quality is splendid, good sealing effect, environmental protection, safety, and to food and environmental friendliness, and preparation technology is simple and convenient.In the component of fluid sealant, the large usage quantity of filler, precipitated calcium carbonate is changed into the ground calcium carbonate that granule is thinner simultaneously.In order to make fluid sealant be capable of withstanding high temperature, the consumption of calcium zinc stabilizer is strengthened.In fluid sealant, add Oleum Brassicae campestris, on the one hand make fluid sealant safety and sanitation, on the other hand make fluid sealant more lubricate, preferably make it meet the Shooting Technique of bottle cap.Test shows, when PVC paste resin polymerization degree is 1000, excessive to the viscosity influence of fluid sealant, the viscosity of fluid sealant is too high to be made it can not meet dripping of bottle cap to mould technique, and the surface quality of bottle cap is had an impact by silicon oil viscosity, the size of ground calcium carbonate simultaneously.The degree of polymerization is the PVC paste resin of 1250, and dimethyl-silicon oil viscosity is 50mpa s, and ground calcium carbonate mesh number is that the dripping of bottle cap that meet that fluid sealant that 1250 mesh are made can be best moulds technique, and makes the surface quality of bottle cap good.Compared with prior art, asepsis environment-protecting polycinyl chloride fluid sealant pad in tinplate bottle cap prepared by the present invention, without phthalic ester plasticizer in fluid sealant, meet food safety requirements, meet RoHS instruction, it is a kind of to food and eco-friendly fluid sealant, and add the consumption of filler, reduce production cost, be a kind of low price, high temperature resistant, good sealing effect, screw conveniently, the fluid sealant of asepsis environment-protecting.
