The present invention has carried out the experiment of three kinds of combination process altogether:
1. then spraying one layer of coating on glue surface first hot-fusible pressure-sensitive adhesive blade coating to applying on silicon barrier paper；Table to be coated
After dry, coating and glue-line are integrally pasted on HDPE sheet material.Such bonding effect is preferable, but will appear cracking after coating surface drying
Phenomenon, therefore abandon such combination process.
2. first spraying one layer of coating on applying silicon barrier paper, then hot-fusible pressure-sensitive adhesive is scratched onto coating, finally in glue
Surface mount on HDPE sheet material.When lab scale, since condition is more simple and crude, when scraping rubberised layer, easily coating is swept (due to applying
Layer and painting silicon barrier paper are easy to be detached from).But the production after industrialization amplification of such combination process is feasible.
3. first spraying one layer of coating on applying silicon barrier paper, then hot-fusible pressure-sensitive adhesive is scratched onto HDPE sheet material, finally
Coating is pasted on film surface again.Such combination process is preferable, but when making cement test, coating occurs and glue-line is detached from now
As, therefore combination process is adjusted are as follows: after on hot-fusible pressure-sensitive adhesive blade coating to HDPE sheet material, painting is pasted again after being heated to 80 DEG C
Layer.
Two, adhesive layers and cement mortar peeling strength test
180 ° of disbonded tests of the splicing sample that flexible material is bonded with rigid material are: two pieces by viscous material adhesive
It is prepared into splicing sample, then will be glued sample and peeled off with defined rate from the opening of splicing, two pieces of adherends are along quilt
The direction of viscous face length is gradually disengaged.Splicing face is arranged essentially parallel to by the peeling force that flexible adherend is applied.
The preparation of 2-1. sample
First lotion is sprayed on barrier paper, it is spare that long 250mm, the piece of width 50mm size are cut after surface drying.Prepare to grow again
The HDPE sheet material of 250mm, width 50mm size.Then pressure-sensitive adhesive agent is scratched to coating or HDPE on piece and (selects one when blade coating
The glass bar of segment length 150mm, both ends wind the copper wire of a loop diameter 0.3mm respectively).After the completion of sample, and entirely it is being glued
Apply uniform pressure on face, recommends to apply pressure up to 1MPa.Cement testing is finally carried out, the cement conservation period is 7 days.Often
The number of a lot number test is no less than five.
2-2. experimental condition
This test carries out on SANA type micro-control electronic universal tester, selects tensile speed 100mm/min, is tried
It is as shown in the table for the Average peel force of sample and average peel strength data.
2-3. test result
This experimental test raw sample, 7-20-P1 waterproof roll and 7-20-PB2700 waterproof roll and cement mortar bond
Stripping performance afterwards, test result is as shown in table 4-1, table 4-2 and table 4-3.In table 4-3, sample 1,2,3,4 is all to use
The third combination process, wherein 1 is direct combination, 2,3,4 be heated to 100 DEG C, 80 DEG C, 60 DEG C respectively after carry out it is compound.
Stripping performance after 7-20-PB2700 waterproof roll is bonded with cement mortar is integrally relatively low, and individual number is too low.
It is influence of each component of the present invention to APAO hot-fusible pressure-sensitive adhesive performance below
The mixed influence to stripping performance of two kinds of matrix resins of 5-1.
When preparing hot-fusible pressure-sensitive adhesive, two kinds of matrix resins is selected to use (total amount 20% is constant) with, two kinds of matrix resin difference
Are as follows: APAO792 and POE8180, tackifier are C5 Petropols (mass fraction 45%), and plasticizer is PB2700 (mass fraction
35%) stripping performance of hot-fusible pressure-sensitive adhesive, is measured, as shown in Figure 1；
As shown in Figure 1, the stripping performance of glue is best when APAO792 dosage maximum (20%), with the addition of POE8180,
Stripping performance gradually weakens.
When two kinds of matrix resins selections are APAO792 and APAO508, sense organ finds that its tack is obviously poor, therefore abandons
Secondary series formula.
5-2. changes influence of the tackifier dosage to stripping performance
When preparing hot-fusible pressure-sensitive adhesive, select matrix resin for APAO792 (100 parts), plasticizer is PB2700 (175 parts),
Change tackifier C5 Petropols dosage (to be respectively as follows: 175 parts, 200 parts, 225 parts, 250 parts, 275 parts, be converted into mass fraction
Be respectively as follows: 39%, 42%, 45%, 48%, 50%).The stripping performance of hot-fusible pressure-sensitive adhesive is measured, as shown in Figure 2；
As shown in Figure 2, with the increase of C5 Petropols dosage, the peel strength of glue is gradually increased, when C5 Petropols
When dosage reaches 45%, peel strength reaches maximum, and later with the increase of C5 Petropols dosage, peel strength gradually drops again
It is low.
5-3. changes influence of the plasticizer type to stripping performance
Under identical formula: m (APAO792): m (C5 Petropols): m (tackifier)=20:45:35 is selected different
Hot-fusible pressure-sensitive adhesive is made in type plasticizer (P1, P2, PB2700, PB950 and PB300).The stripping performance of hot-fusible pressure-sensitive adhesive is measured,
As shown in Figure 3；
From the figure 3, it may be seen that for different types of plasticizer, it is maximum using the peel strength of glue when PB2700.For difference
The PB of molecular weight, with the reduction of molecular weight, peel strength is gradually decreased, when molecular weight drops to 300, peel strength decline compared with
Fastly, stripping performance is very poor at this time.
The mixed influence to stripping performance of two kinds of plasticizer of 5-4.
When preparing hot-fusible pressure-sensitive adhesive, two kinds of plasticizer is selected to use (total amount 35% is constant) with, two kinds of plasticizer from P1, P2,
It is chosen in PB2700, PB950 and PB300, matrix resin is APAO792 (mass fraction 20%), and tackifier are C5 petroleum tree
Rouge (mass fraction 45%).
5-4-1.PB2700 the influence to stripping performance mixed with P1
This group of formula selects PB2700 mixed with P1, the stripping performance of hot-fusible pressure-sensitive adhesive is measured, as shown in Fig. 4；
As shown in Figure 4, the stripping performance of glue is best when PB2700 dosage maximum (35%), with the addition of P1, fissility
First can comparatively fast it decline, after P1 is added to half, decrease speed is slack-off.
5-4-2.PB2700 the influence to stripping performance mixed with P2
This group of formula selects PB2700 mixed with P1, the stripping performance of hot-fusible pressure-sensitive adhesive is measured, as shown in Fig. 5；
As shown in Figure 5, the stripping performance of glue is best when PB2700 dosage maximum (35%), and with the addition of P2, removing is strong
Degree is gradually reduced.
5-4-3.PB2700 the influence to stripping performance mixed with PB950
This group of formula selects PB2700 mixed with PB950, measures the stripping performance of hot-fusible pressure-sensitive adhesive, as shown in Figure 6；
It will be appreciated from fig. 6 that with the increase of PB950 dosage, the peel strength of glue will appear a peak value, i.e., when PB950 is used
When amount reaches 10%, peel strength reaches maximum, and later with the increase of PB950 dosage, peel strength gradually decreases again.Simultaneously
We it can be found that with PB950 dosage increase, most start peel strength variation it is more slow, when PB950 dosage reaches one
After half, peel strength reduces very fast.
5-4-4.PB2700 the influence to stripping performance mixed with PB300
This group of formula selects PB2700 mixed with PB300, measures the stripping performance of hot-fusible pressure-sensitive adhesive, as shown in Figure 7:
As shown in Figure 7, with the increase of PB300 dosage, the peel strength of glue will appear a peak value, i.e., when PB300 is used
When amount reaches 2.5%, peel strength reaches maximum, and later with the increase of PB300 dosage, peel strength starts to reduce again, and
And it reduces very fast.
