The hot melt adhesive test sample preparation die comprises a die base disc, wherein the die base disc is provided with a groove; a first kraft paper layer is arranged on the die base disc; a steel sheet is arranged on the kraft paper layer and is positioned inside the groove; a hot melt adhesive piece is arranged on the steel sheet; a polyethylene piece is arranged on the hot melt adhesive piece; a second kraft paper layer is arranged on the polyethylene piece; and a steel plate is arranged on the second kraft paper layer.
Description
Technical field
The utility model relates to technical field of polymer materials, and is particularly related to a kind of hot melt adhesive test sampling die.
Background technology
Hot melt adhesive is take thermoplastic resin or thermoplastic elastomer as principal ingredient, the not solvent-laden solid adhesive agent of making through melting mixing take tackifier, plastifier, antioxidant, fire retardant and filler as adding ingredient.As long as heat just melting during use, namely bonding is got up after cooling, often makes the forms such as granular, bar-shaped, cord shape, film-form, and it can be to various materials, carries out bondingly as timber, paper, fiber, metal, plastics etc., and usable range is wider.
Peel strength is an important indicator of hot melt adhesive performance, at present in the test of test hot melt adhesive peel strength, be used for test and lean on manual operation fully with the sample preparation of hot melt adhesive sample, the operator is had relatively high expectations, operating environment requires to carry out in baking oven, temperature is higher, operation easier is larger, and when exerting pressure by operator's manual operations, pressure is controlled unstable, therefore cause the less stable of sample, the possibility that occurs larger difference with sample room is larger.
The utility model content
In view of this, the utility model is intended to solve the disappearance that prior art is intended to solve prior art.
The utility model provides a kind of hot melt adhesive test sampling die, and it comprises: the mould chassis has groove; The first layers of kraft paper is arranged on described mould chassis; Steel disc is arranged on described layers of kraft paper and is positioned at described groove; Hot-melt film is arranged on described steel disc; Polythene strip is arranged on described hot-melt film; The second layers of kraft paper is arranged on described polythene strip; Steel plate is arranged on described the second layers of kraft paper.
Further, the quantity of described groove is two or more.
In sum, the hot melt adhesive test sampling die that the utility model provides, be applicable to T-shaped peel strength and 180 ° of peel strengths, changed in prior art, the drawback that operating personnel operate in hot environment in the sample preparation of hot melt adhesive peeling strength test makes operating personnel can at room temperature carry out the sample preparation operation.And can guarantee the stability of sample preparation by accurately setting constant sample preparation pressure, reduce with sample room difference, and prevent the damage of mould and sample.In addition, the mould of employing has a plurality of grooves, can prepare simultaneously a plurality of samples.
Description of drawings
Figure 1 shows that the hot melt adhesive peeling strength test method for making sample process flow diagram that the utility model one embodiment provides;
Figure 2 shows that the hot melt adhesive test sampling die structural representation that the utility model one embodiment provides;
Figure 3 shows that the hot melt adhesive test sampling die sectional view that the utility model one embodiment provides.
Embodiment
For the purpose of this utility model, feature are become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
See also Fig. 1, it is depicted as the utility model one embodiment
This hot melt adhesive peeling strength test method for making sample, it comprises the following steps:
S110 provides a reeded mould of tool;
S120 is at described mould upper berth ground floor kraft;
S130 is contained in steel disc on ground floor kraft and is positioned at the groove of mould;
S140 is placed on hot-melt film on described steel disc;
S150 carries out preheating to described hot-melt film;
S160 is placed in polythene strip on described hot-melt film after described hot-melt film is softening;
S170 covers steel plate at described polythene strip upper berth second layer kraft;
S180 pushes described hot-melt film;
The cooling rear taking-up sample of S190.
The method is applicable to T-shaped peel strength and 180 ° of peel strengths.Changed the drawback that will operate in the past in hot environment, but at room temperature just sample preparation.
In the utility model embodiment, described mould is put on baking oven or compression molding instrument described hot-melt film is carried out preheating.
Can be with baking oven or compression molding instrument during preheating.Because heat under sealed environment, the used time is shorter with baking oven, but requires affected speed, and the compression molding instrument is to heat under open environment, so preheating time is longer, but to the operating speed no requirement (NR).
In the utility model embodiment, utilize the compression molding instrument that mould is pushed.Constant pressure can be provided, improve sample preparation stability, reduce with sample room difference.
In the utility model embodiment, during sample preparation, pressure can not be too little, prevents that sample preparation is not firm.Also can not ether large, prevent that mould and sample from damaging.The pressure of extruding is controlled at 4.5MPa to 5.5Mpa, and the time of exerting pressure is 250 seconds to 350 seconds.After cooling, sample is taken out.Identical pressure and time have been improved the stability of sample preparation, and have broken away from originally and operate in baking oven, have reduced operation easier.
See also Fig. 2, it is depicted as the hot melt adhesive test sampling die structural representation that the utility model one embodiment provides.
This mould has mould chassis 210, has groove 220 on it.In the present embodiment, the quantity of described groove is two or more, can prepare simultaneously a plurality of samples, has improved sample preparation efficient.
See also Fig. 3, it is depicted as the hot melt adhesive test sampling die sectional view that the utility model one embodiment provides.
This mould comprises: mould chassis 210 has groove 220; The first layers of kraft paper 310 is arranged on described mould chassis 210; Steel disc 320 is arranged on described layers of kraft paper 310 and is positioned at described groove 220; Hot-melt film 330 is arranged on described steel disc 320; Polythene strip 340 is arranged on described hot-melt film 330; The second layers of kraft paper 350 is arranged on described polythene strip 340; Steel plate 360 is arranged on described the second layers of kraft paper 350.
In sum, the hot melt adhesive test sampling die that the utility model embodiment provides, be applicable to T-shaped peel strength and 180 ° of peel strengths, changed in prior art, the drawback that operating personnel operate in hot environment in the sample preparation of hot melt adhesive peeling strength test makes operating personnel can at room temperature carry out the sample preparation operation.And can guarantee the stability of sample preparation by accurately setting constant sample preparation pressure, reduce with sample room difference, and prevent the damage of mould and sample.In addition, the mould of employing has a plurality of grooves, can prepare simultaneously a plurality of samples.
Although the utility model discloses as above with preferred embodiment; so it is not to limit the utility model; have in technical field under any and usually know the knowledgeable; within not breaking away from spirit and scope of the present utility model; when being used for a variety of modifications and variations, therefore protection domain of the present utility model is as the criterion when looking claims person of defining.
