self-adhesive performance test analysis table after washing

The self-adhesion ground mat of interval gum that this embodiment provided, contrast test data can know, and the interval sets up the different thickness of gum layer and washing number of times, temperature, produces certain influence to ground mat non-slip properties. The thickness of the back glue layer arranged at intervals is analyzed to have a certain causal relationship with aging resistance, and under the conditions of repeated washing and high temperature, the thinner the back glue layer is, the poorer the aging resistance is, the poorer the stability of the material is, and therefore, the poorer the anti-skid property is.

The test data can be obtained, the thickness of the gum layer is 0.05-5.0 mm, and the gum layer has good anti-skid property and stability. The thickness of the gum layer is 0.5-3.0 mm, and the anti-skid property and the stability are better. Analysis shows that when the sample with the thickness of 5.0 mm of the back adhesive layer is washed by water for 30 times, the antiskid property is reduced due to partial degumming of the back adhesive layer, and the non-back adhesive is aged.

Example 3:

The self-adhesive ground mat with the back adhesive at intervals provided by the embodiment is tested as follows:

and (5) testing: washability and skid resistance test of self-adhesive interval back glue layers in various shapes

Test samples: main parameter information: quantity: 3, dividing the blocks; specification: 40 x 60 cm; a floor mat body: a non-woven layer; the thickness of the gum layer is 1.0 mm; the spacing is 3.0 cm. The test data are as follows:

washing fastness and skid resistance test analysis table of self-adhesive interval back glue layers in various shapes

The above test data show that the washing resistance is as follows: the washing of the part a is not degummed 51 times, the washing of the part b is not degummed 46 times, the washing of the part c is not degummed 40 times, the analysis can obtain the parts a, b and c, the washing can be carried out 40 times without degummed, and the situation that the gum is distributed at intervals to meet the water permeability and simultaneously give consideration to good washing fastness is shown. The a pattern continuous interval strip can be washed for 50 times without glue stripping, and the interval strip is best.

Anti-skid performance: the antiskid grade of the washing with water for 50 times is excellent, the antiskid grade of the washing with water for 44 times is excellent, the antiskid grade of the washing with water for 28 times is excellent, and the three grades of a, b and c can be obtained through analysis, so that the self-adhesive antiskid property can be still maintained after the washing with water for 28 times, and the situation that the water permeability is met and the good antiskid performance is considered when the back adhesive is distributed at intervals is shown. The antiskid performance of the a continuous spaced strip is not reduced after washing for 50 times, which indicates that the spaced strip is optimal, has better antiskid property and excellent self-adhesive force.

In summary, the conclusions are as follows:

examples 1 to 3, experiments 1 to 5 show that the back adhesive layer 4 of the self-adhesive floor mat with the spaced back adhesive realizes three main technologies of self-adhesion, anti-slip, water permeation and washing resistance, and the determining elements depend on the spaced distribution and thickness of the back adhesive layer 4.

Through analysis, the arrangement of the back glue layers at intervals is obviously superior to the arrangement of the back glue layers on the full surface. The spaced strip-shaped back glue layer is optimal. When the thickness of the interval gum layer is 0.05-5.0 mm, three main technologies of self-adhesion antiskid, water permeation and washing resistance can be realized. When the back glue layer is proper in thickness, the best self-adhesion antiskid performance, water permeability and washing resistance can be exerted. The thicker the back glue layer, the poorer the washing fastness, and the higher the washing degumming rate. The thinner the thickness of the back adhesive layer is, the poorer the aging resistance is, the lower the back adhesive elasticity is, and the poorer the self-adhesion anti-slip performance is. The thickness of the interval gum layer is more preferably 0.08-3.0 mm; the thickness of the interval back glue layer is 0.1-2.0 mm optimal.
