The adhesive for the cushion body is suitable for bonding layers of the composite cushion body, has high bonding strength and prolongs the service life of the cushion body.
Description
Technical Field
The invention relates to the field of foaming pads, in particular to an adhesive for a pad body.
Background
The adhesive is used for connecting the same or two or more than two homogeneous or heterogeneous products (or materials) together, and has an organic or inorganic, natural or synthetic substance with enough strength after being cured. The cushion body needs to be formed by compounding multiple layers for realizing specific functions or multiple functions, but the existing adhesive has poor bonding strength and is easy to degum after being used for a short time or meeting water.
Disclosure of Invention
The invention aims to provide an adhesive with high bonding strength for a cushion body, which solves the problems of poor bonding force and the like generated by the traditional process.
In order to achieve the purpose, the invention provides the following technical scheme:
the application discloses an adhesive for a cushion body,
the adhesive for the pad body comprises raw materials including vinyl chloride-vinyl acetate copolymer and organic solvent, wherein the raw materials comprise the following components in percentage by mass:
20-40 parts of vinyl chloride-vinyl acetate copolymer;
50-90 parts of organic solvent.
Preferably, in the above adhesive for a mat body, the organic solvent is a mixed solution of xylene and cyclohexanone.
Preferably, in the above adhesive for a mat body, the mass ratio of the xylene to the cyclohexanone is 2: 3-4: 5.
the application also discloses a preparation method of the adhesive for the cushion body,
the preparation method comprises the following steps:
1) preparing the materials
Using the first elevated tank to count dimethylbenzene, using the second elevated tank to count cyclohexanone, and weighing the vinyl chloride-vinyl acetate copolymer;
2) preparation of organic solvent
Pumping dimethylbenzene and cyclohexanone into a stirring kettle by using a self-priming pump, and continuously stirring for 3-4 h;
3) dissolving the mixture
Adding the vinyl chloride-vinyl acetate copolymer into the stirred organic solvent from a feeding port of the stirring kettle, and continuously stirring until the vinyl chloride-vinyl acetate copolymer is completely dissolved to obtain an adhesive for the pad body;
4) and packaging for later use
The adhesive for the pad body is contained in a sealed tank body.
Compared with the prior art, the adhesive for the cushion body is suitable for bonding layers of the composite cushion body, has high bonding strength and prolongs the service life of the cushion body.
Detailed Description
The invention is further illustrated by the following examples: the invention will be better understood from the following examples. However, those skilled in the art will readily appreciate that the specific material ratios, process conditions and results thereof described in the examples are illustrative only and should not be taken as limiting the invention as detailed in the claims.
The preparation method of the adhesive for the pad body comprises the following steps:
1) preparing the materials
Weighing 30 parts by weight of dimethylbenzene by using a first elevated tank, weighing 40 parts by weight of cyclohexanone by using a second elevated tank, and weighing 30 parts by weight of vinyl chloride-vinyl acetate copolymer;
2) preparation of organic solvent
Pumping dimethylbenzene and cyclohexanone into a stirring kettle by using a self-sucking pump, and continuously stirring for 3 hours at normal temperature and normal pressure;
3) dissolving the mixture
Adding the vinyl chloride-vinyl acetate copolymer into the stirred organic solvent from a feeding port of the stirring kettle, and continuously stirring until the vinyl chloride-vinyl acetate copolymer is completely dissolved to obtain an adhesive for the pad body;
4) and packaging for later use
The adhesive for the pad body is contained in a sealed tank body.
In the using process, the glue is smeared on the bonding surface of the composite pad body by using the existing equipment, and is kept stand or air-cooled until the glue is completely fixed, the pad body is made of PVC, the structure of the pad body is the same as that of the adhesive, the pad body is placed in water for soaking test, and the bonding time is at least prolonged by 20 times.
In summary, the adhesive for the cushion body is suitable for bonding layers of the composite cushion body, has high bonding strength and prolongs the service life of the cushion body.
It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps closely related to the scheme according to the present invention are shown in the embodiments, and other details not closely related to the present invention are omitted.
Finally, it should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
