Examination: spray gun spraying is respectively adopted in carrying out instant plane adhesion on the leather got ready, test result is as shown in table 2.
2 embodiment 1 to 3 of table obtains the adhesive property test result of sample 1 to 3 outside water-soluble spraying glue and glue spraying
From table 2 it can be seen that the water-soluble spraying glue that embodiment 1 to 3 obtains has the performance of good bonding, and at 60 DEG C
Under the conditions of heat dry, embodiment 1 to 3 obtain water-soluble spraying glue usually time be longer than other three outer samples, illustrate embodiment 1 to 3
The water-soluble spraying glue of acquisition has good heat resistance.
2, embodiment 2 is obtained into water-soluble spraying glue and comparative example 1 to 3 obtains water-soluble spraying glue and compares test, be respectively adopted
Two-component spray gun, which is sprayed on the leather got ready, carries out instant plane adhesion, and test effect is as shown in table 3.
The adhesive property test result for the water-soluble spraying glue that 3 embodiment 2 of table and comparative example 1 to 3 obtain
From table 3 it can be seen that the adhesive property that embodiment 2 obtains water-soluble spraying glue is better than comparative example 1,2 and 3, illustrate to select
The modifies HDI of trimerization is better than selecting the water-soluble spraying glue of other fixatives as the water-soluble spraying glue of fixative.
3, embodiment 2 is obtained into water-soluble spraying glue and comparative example 4, comparative example 5 obtains water-soluble spraying glue and carry out adhesive property test,
It two-component spray gun is respectively adopted is sprayed on the leather got ready and carry out instant plane adhesion, test effect is as shown in table 4.
The adhesive property test result for the water-soluble spraying glue that 4 embodiment 2 of table and comparative example 4 to 5 obtain
From table 4, it can be seen that the additive amount of Isocyanates curing agent is very heavy in the preparation method of water-soluble spraying glue
It wants, if addition is very few, hardly possible is dry after just will appear glue spraying, it is difficult to the case where being bonded appearance, if additional amount is excessive, just
The viscosity that will cause glue spraying is larger, and spray gun is difficult to spray, and spraying difficulty is larger.
4, embodiment 2 is obtained into water-soluble spraying glue and oiliness glue spraying carries out spraying property test in same substrate, bonding is strong
Degree testing standard is to break plank and cloth into two with one's hands with hand after 1 minute, and sponge, leather is to the extent of the destruction after patch；Heat resistance is at 60 DEG C
It is tested 1 hour in oven；Weatherability is tested 24 hours in 60 DEG C of ovens.Test result is as shown in table 5.
The performance test results of 5 embodiment 2 of table acquisition water-soluble spraying glue and oiliness glue spraying
| Performance compares | Tack | Heat resistance | Adhesive strength | Weatherability |
| Embodiment 2 | It is bonded immediately | It is heat-resist | It destroys completely | Good weatherability |
| Gu Kangli 189 | It is bonded immediately | Intensity is lower after 1 hour | Partial destruction | Intensity is lower after 24 hours |
As can be seen from Table 5, the heat resistance of aqueous double-component glue spraying and weatherability and adhesive strength are significantly better than oiliness
Glue spraying.
5, embodiment 2 obtains water-soluble spraying glue compared with oiliness glue spraying changes adhesive property with quantity for spray: spraying to sponge
Enter same amount of different glue sprayings, bonding situation is as shown in table 6.
The performance test results of 6 embodiment 2 of table acquisition water-soluble spraying glue and oiliness glue spraying
| Spray glue amount | Half of cross | One cross | One and half crosses | Two crosses |
| Embodiment 2 | It can be bonded, but intensity is lower | It is bonded immediately | It is bonded immediately | It is bonded immediately |
| Gu Kangli 189 | It cannot be bonded | Adhesive strength is low | It is bonded immediately | It is bonded immediately |
Note: it sweeps away to connect for one time and perpendicular sweeps one time as a cross
As can be seen from Table 6, embodiment 2 obtains water-soluble spraying glue in the case where half of cross glue spraying amount, can achieve bonding,
But adhesive strength is low, and in the case where the glue spraying amount of a cross, so that it may realization is bonded immediately；And oiliness glue spraying is half
It can not achieve bonding under a cross glue spraying amount, may be implemented to be bonded under the glue spraying amount of a cross, but adhesive strength is low, only
Have just to be able to achieve under the glue spraying amount of one and half crosses and be bonded immediately, obtaining water-soluble spraying glue using water embodiment 2 is to compare saving
Glue consumption.
To sum up, water-soluble spraying glue provided by the invention can make substrate carry out quickly generating bonding, being capable of General Promotion factory
