Description
Technical field
The present invention relates to technical field of macromolecule adhesive, and in particular to a kind of adhesive and preparation method thereof.
Background technique
In recent years, packaging industry had risen a kind of reform tide, replaced various packing materials with honeycomb cardboard.Use honeycomb paper
The product for the packaging group that plate is made into was not only simple and convenient, but also saved cost.During being packed using cellular board, it usually needs will
Cellular board is bonded well with pearl cotton and is combined with each other, but pearl cotton is a kind of material for being difficult bonding, current gluing
Agent for bond pearl cotton and cellular board when usually there will be adhesion strength and hold viscosity it is poor, it will usually occur put after bonding
It sets first segment time cellular board and pearl cotton separation perhaps applies small power and easily separates or occur side for cellular board and pearl cotton
The phenomenon that edge cracking crimping.Such as Chinese patent CN104031581A discloses a kind of wood pencil environment-friendly type high performance water
Property adhesive, by ethene-vinyl acetate copolymer emulsion, the carboxy-modified lotion of ethylene-vinyl acetate and acrylate pressure-sensitive adhesive
Lotion composition, although the adhesive is between timber and timber, adhesion strength is high between timber and pencil-lead, when being applied to
Pearl cotton is this when being difficult the material of bonding, and adhesion strength is low, and it is poor to hold viscosity, is not able to satisfy cellular board and the compound packet of pearl cotton
Reload request.
Therefore, it is improved for existing binder, prepares a kind of bonding use for being suitable for being packed for pearl cotton,
The high-strength composite for being packed for the materials such as pearl cotton and cellular board is promoted, for promoting the development of packaging industry, promotes package
Matter has great importance.
Summary of the invention
In order to overcome the drawbacks of the prior art, the object of the present invention is to provide a kind of adhesive, applied to being packed for pearl
The bonding of the materials such as cotton material and cellular board is compound, and adhesion strength is high, and hold viscosity energy is good.
Meanwhile the present invention also resides in and provides a kind of preparation method of adhesive.
In order to achieve the goal above, the technical scheme adopted by the invention is that:
A kind of adhesive is prepared by each component of following parts by weight: 55~66 parts of pressure-sensitive adhesive emulsion, Modified Polychloroprene
18~25 parts of latex, 15~20 parts of ethene-vinyl acetate copolymer emulsion, 0.4~0.6 part of defoaming agent, 0.2~0.4 part of thickener.
Optionally, the pressure-sensitive adhesive emulsion is the permanent big high solid content pressure-sensitive adhesive of Yanggu.
Optionally, the solid content of the pressure sensitive adhesive is 58%.
Optionally, the Modified Polychloroprene latex is BDL-916 latex.
Optionally, the ethene-vinyl acetate copolymer emulsion is EP-710VAE lotion.
Optionally, the defoaming agent is Fo Mate MO 2190AC.
Optionally, the thickener is the permanent big HD-7560 of Yanggu.
The preparation method of above-mentioned adhesive, including each raw material is mixed evenly, it filters, that is, completes.
Optionally, described that each raw material is mixed evenly method particularly includes: to sequentially add and change in pressure-sensitive adhesive emulsion
Property neoprene latex and ethylene-vinyl acetate copolymer emulsion, after stirring 30 minutes, thickener is added dropwise, stirs 20 after being added dropwise
After minute, defoaming agent is added dropwise, stirs 40 minutes, that is, completes after being added dropwise.
Optionally, described to be filtered into 150 mesh filter screens.
Invention adhesives make pressure-sensitive adhesive emulsion, Modified Polychloroprene latex and ethene-vinyl acetate copolymer emulsion compounding
With and adding the defoaming agent and thickener of suitable amounts, three kinds of lotions with gumminess phase in physical behavior between each other
Mutually supplement, generates modifying function in chemical molecular structure between each other, makes to generate synergistic function between its three, so that
The adhesive of preparation is strong to the Pearl wool material bonding force of hardly possible bonding, and the compound plate come out is longitudinal sectional, crosscutting all without rolling phenomenon.
Further, comprehensive performance of the product of the uniform type produced due to different manufacturers in physics and chemistry
On all have a certain difference, and usually single product can only be illustrated the character of this product, and by itself and other
Performance after product mix compounding is usually unknown and unforeseen, then the present invention is in order to further mention
Rise performance of the prepared adhesive in terms of Pearl wool material bonding, the production of creative each gumminess emulsion materials of selection
Producer and model promote every comprehensive performance of product so that can preferably generate synergistic function between each component.
The preparation method of invention adhesives, it is easy to operate, it is easily controllable, it is suitable for industrial application, and prepare
Product apply it is convenient, can roller coating, can also be applied with hand.
Further, preparation method of the present invention specifically limits charging sequence, feed way, mixing time of each raw material etc.,
For example thickener and defoaming agent are limited by the way of being added dropwise, adequately promote each raw material to be uniformly mixed, further promotes product
The stability of performance enhances it to the adhesion strength of Pearl wool material and bonding persistence.
