Description
Technical field
The present invention relates to binding agent field, be specifically related to a kind of adhesive composition and preparation method thereof.
Background technology
For the binding agent of the little year calendar of this formula or note can be divided generally by the good binding agent of viscosity, at present, most popular is exactly polyurethanes binding agent, wherein especially with Henkel 369
#glue is the most frequently used.Be characterized in that viscosity is good, be not easy to parch, flexible, can elongate, but point originally stack and can after-tack after parching, cause heavily dividing this, and heavily dividing in this process, easily cause product to have loose page phenomenon, this does not meet again specification of quality, increase again wastage rate and rework rate, be unfavorable for that operation also affects production schedule simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide one to be convenient to brush coating, parches fast, does not after-tack, be beneficial to adhesive composition of rear process operations and preparation method thereof after dividing this.
In order to solve above technical problem, the invention provides a kind of adhesive composition, by volume number meter comprises:
Polyurethanes binding agent 15 ~ 25 parts;
Vinyl Acetate Copolymer binding agent 15 ~ 30 parts.
Preferably, described polyurethanes binding agent is Henkel 369
#glue.
Preferably, described Vinyl Acetate Copolymer binding agent is polyvinyl acetate emulsion type III glue.
Preferably, described adhesive composition, by volume number meter comprises:
Polyurethanes binding agent 18 ~ 21 parts;
Vinyl Acetate Copolymer binding agent 20 ~ 25 parts.
Present invention also offers a kind of preparation method of adhesive composition according to claim 1, comprising:
Polyurethanes binding agent is mixed by proportioning with Vinyl Acetate Copolymer binding agent, stirs and obtain adhesive composition.
Preferably, described stirring is specially:
The mixture of described polyurethanes binding agent and Vinyl Acetate Copolymer binding agent is placed in the first agitator and revolves stirring 10 ~ 20 minutes, obtain the first mixed solution;
Described first mixed solution is placed in the second agitator, mixes 10 ~ 20 minutes up and down.
Preferably, described polyurethanes binding agent is Henkel 369
#glue.
Preferably, described Vinyl Acetate Copolymer binding agent is polyvinyl acetate emulsion type III glue.
Adhesive composition provided by the invention is owing to containing polyurethanes binding agent and Polyvinyl acetate, and polyurethanes binding agent to have viscosity good, be not easy to parch, flexible, tractile feature, the speed that parches of polyvinyl acetate (PVA) binding agent is fast, and the adhesive layer formed after dry is harder.The adhesive composition obtained after being mixed in proportion by two kinds of binding agents can take into account the characteristic of binding agent in two, is convenient to brush coating, and parch fast, do not after-tack after dividing this, be beneficial to rear process operations, and loss is low, Products quality has very large lifting.
Present invention also offers a kind of preparation method of described adhesive composition, two kinds of binding agents are mixed.Preparation method is simple, use minimum operation processability to be well applicable to the adhesive composition of the gluing publication of multipage, in the preparation process of especially little year calendar and note, difficulty can not be caused to follow-up production, reduce production cost, be applicable to large-scale production.
Embodiment
In order to understand the present invention further, below in conjunction with embodiment, the preferred embodiments of the invention are described, but should be appreciated that these describe just as further illustrating the features and advantages of the present invention instead of the restriction to patent requirements of the present invention.
The invention provides a kind of adhesive composition, comprising polyurethanes binding agent and Vinyl Acetate Copolymer binding agent, described polyurethanes binding agent and Vinyl Acetate Copolymer binding agent by volume number meter comprise:
Polyurethanes binding agent 15 ~ 25 parts;
Vinyl Acetate Copolymer binding agent 15 ~ 30 parts.
According to the present invention, described polyurethanes binding agent can be divided into foaming adhesive or non-foamed binding agent according to type of bond, the polyurethanes binding agent of general foaminess needs to be cured process, and polyurethanes binding agent generally the moisture that can absorb in air foam and solidify and be connected with medium, the polyurethanes binding agent that the present invention uses preferably uses Henkel 369
#glue.Its tack coat viscosity formed is good, is not easy to parch, flexible, tractile feature.But when described polyurethanes binding agent is used alone in the preparation process of little year calendar or note, divide after binding agent parches and originally stack and can after-tack, cause heavily dividing this, and easily cause product to have loose page phenomenon heavily dividing in this process, this does not meet specification of quality again, increase again wastage rate and rework rate, be unfavorable for that operation also affects production schedule simultaneously.So need accelerate binding agent the speed that parches and reduce parch rear tack coat elasticity, need Henkel 369
#glue and other binding agents used in combination.
It is hardening that Vinyl Acetate Copolymer binding agent parches rear tack coat, there is no elasticity, easy cracking when by described Vinyl Acetate Copolymer binding agent and polyurethanes binding agent with the use of, the adhesive composition obtained can be good at the shortcoming of customer service bi-material, mutual modification, thus obtain a kind of novel work-ing life effectively can improving the gluing printed matters of multipage such as little year calendar and note.According to the present invention, described polyvinyl acetate emulsion elects polyvinyl acetate emulsion type III glue as.
According to the present invention, described adhesive composition, by volume number meter preferably includes: polyurethanes binding agent 18 ~ 21 parts; Vinyl Acetate Copolymer binding agent 20 ~ 25 parts.Being more preferably polyurethanes binding agent and Vinyl Acetate Copolymer binding agent is 1:1 mixing by volume.
Present invention also offers a kind of preparation method of described adhesive composition, comprising:
Polyurethanes binding agent is mixed by proportioning with Vinyl Acetate Copolymer binding agent, stirs and obtain adhesive composition.
According to the present invention, because described polyurethanes binding agent is preferably Henkel 369
#glue.Polyurethanes, described Vinyl Acetate Copolymer binding agent is preferably polyvinyl acetate emulsion type III glue, is aqueous binders, so can be blended.But due to Henkel 369
#the viscosity of glue is greater than polyvinyl acetate emulsion type III glue, so need when stirring to use special method, according to the present invention, described stirring is specially:
The mixture of described polyurethanes binding agent and Vinyl Acetate Copolymer binding agent is placed in the first agitator and revolves stirring 10 ~ 20 minutes, obtain the first mixed solution;
Described first mixed solution is placed in the second agitator, mixes 10 ~ 20 minutes up and down.
According to the present invention, described first agitator and the second agitator can be unified agitator, also can be two agitators, the present invention preferably pours the first mixed solution obtained into second agitator from the first reaction stirrer, and the mixed solution of levels is mixed fully.According to the present invention, described first agitator and the second agitator include an electric mixing device and a container, and described container is respectively the plastic container of two same volumes.
