Detailed Description
The technical scheme of the present invention will be clearly and completely described in the following in connection with specific embodiments. It will be apparent that the described embodiments are merely some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to avoid open flame heating and baking when using the asphalt waterproof coiled material, a hot melt adhesive layer is coated on the asphalt waterproof coiled material, so that a fire operation is not required. However, the hot melt adhesive layer is easy to be migrated and permeated by small molecular substances or hybrid substances such as waste engine oil, waste heat conducting oil, old tire rubber powder and the like in the asphalt waterproof coiled material modified asphalt adhesive layer, and the substances permeate into the hot melt adhesive layer to enable the hot melt adhesive layer to be swelled and dissolved, so that the adhesive property of the hot melt adhesive is greatly reduced along with the time, and the asphalt waterproof coiled material is easy to fall off and has short service life. Aiming at the problems, the self-adhesive of the asphalt waterproof coiled material is coated on the asphalt waterproof coiled material to prevent the migration and permeation of small molecular substances or hybrid substances such as waste engine oil, waste heat conducting oil, rubber powder of old tires and the like, so that the service life of the asphalt waterproof coiled material is prolonged.
The asphalt waterproof coiled material self-adhesive comprises the following components in percentage by weight:
20-35% of SBS rubber;
5-20% of SIS rubber;
1-10% of naphthenic oil;
0.2-0.3% of antioxidant;
39.7 to 73.7 percent of tackifying resin;
0.1-10% of inorganic filler.
As one embodiment, the asphalt waterproof coiled material self-adhesive comprises the following components in percentage by weight:
20-30% of SBS rubber;
8-15% of SIS rubber;
1.7 to 4.7 percent of naphthenic oil;
0.2-0.25% of antioxidant;
40-60% of tackifying resin;
2-6% of inorganic filler.
SIS rubber and SBS rubber are used as base materials, so that high cohesive force is provided, and good compatibility is achieved. The naphthenic oil is used as a softening agent, has high dissolving power, can be compatible with rubber, improves the processability and the service performance of the hot melt adhesive, and improves the dispersibility and the miscibility of the inorganic filler, so that the inorganic filler has better compatibility with rubber and resin. The addition of the inorganic filler improves the solid content in the self-adhesive, so that the mechanical property of the self-adhesive is improved; meanwhile, the self-adhesive can resist permeation of small molecular substances or hybrid substances, so that the self-adhesive has good stability. The tackifying resin increases the adhesive force of the adhesive layer, improves the stability and is not easy to leak oil; the antioxidant can delay the oxidation of the macromolecular compound; therefore, the self-adhesive of the asphalt waterproof coiled material has better adhesion effect on the nuclear hot melt adhesive of the asphalt waterproof coiled material, can prevent the damage of small molecular compounds and hybrid substances from the asphalt waterproof coiled material to an adhesive layer, and prolongs the service life.
As one embodiment, the tackifying resin is a carbon five resin and/or a hydrogenated petroleum resin. The carbon five resin and/or the hydrogenated petroleum resin are tackifying resins with excellent performance, and are used in combination with SIS rubber and SBS rubber, so that the viscosity of the rubber is remarkably improved, the adhesive force of the polymer is increased, and the initial viscosity is improved. And the molecular weight of the carbon five resin and/or the hydrogenated petroleum resin is about 300-3000, and the carbon five resin and/or the hydrogenated petroleum resin can be well mixed with rubber, naphthenic oil and an antioxidant.
As one embodiment, the carbon five resin is a carbon five resin with a softening point of 90-110 ℃;
the hydrogenated petroleum resin is hydrogenated petroleum resin with a softening point of 90-110 ℃ and/or hydrogenated petroleum resin with a softening point of 130-140 ℃.
The carbon five resin with a specific softening point and the hydrogenated petroleum resin with different softening points are selected as components for adjusting the viscosity, wherein the addition of the hydrogenated petroleum resin with a high softening point (130-140 ℃) can effectively improve the heat resistance of the product, the strength of the glue is increased under the high temperature condition, and the addition of the hydrogenated petroleum resin with a low softening point (90-110 ℃) can play a role in tackifying, so that the combination of the hydrogenated petroleum resin with a low softening point and the hydrogenated petroleum resin can ensure enough adhesive property, improve the online adhesive efficiency and improve the heat resistance of the product.
As one of the embodiments, the weight ratio of the carbon five resin to the hydrogenated petroleum resin is 1: (1-4).

On the one hand, the inorganic filler particles are dispersed in the self-adhesive glue, and the spherical, rod-shaped or lamellar particles block the permeation of small molecular substances and make the permeation become tortuous. On the other hand, in the mixing process, calcium carbonate, barium sulfate, titanium pigment and talcum powder tend to be arranged in parallel due to the action of surface tension, so that in the formed asphalt waterproof coiled material self-adhesive glue, the inorganic filler molecules form a compact layered structure which is arranged in parallel and overlapped up and down, and when small molecular compounds and hybrid substances from the asphalt waterproof coiled material contact with the self-adhesive glue, migration and permeation of the small molecular compounds and the hybrid substances from the asphalt waterproof coiled material are more roundabout and more tortuous when passing through the compact layered structure, and migration and permeation of the asphalt waterproof coiled material are slowed down, so that barrier effect is realized.
As one embodiment, the antioxidant is a phenolic antioxidant and/or a phosphite antioxidant. The phenolic antioxidant and the phosphite antioxidant can delay the oxidation of the macromolecular compound, thereby prolonging the service life of the product.
Preferably, the phenolic antioxidant is one or a combination of more than two of 2, 6-di-tert-butyl-p-cresol, pentaerythritol tetra [ beta- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate ] or n-stearyl beta- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate;
the phosphite antioxidant is tris [2, 4-di-tert-butylphenyl ] phosphite.
The invention also provides a preparation method of the asphalt waterproof coiled material self-adhesive, which comprises the following preparation steps:

Comparative example 1
Comparative example 1 differs from example 1 in that no inorganic filler was added, and other components and preparation methods were the same as example 1.

The asphalt waterproof coiled material prepared in examples 1-6 was subjected to performance test on self-adhesive and the products of comparative examples 1-2.
(1) Barrier test
Taking 27 thermoplastic plastic barrels with covers of the same type of the same manufacturer, and randomly dividing the thermoplastic plastic barrels into 9 groups of three, wherein the blank groups are untreated barrel groups; examples 1-6 groups of asphalt waterproof coiled materials of examples 1-6 are respectively coated with the same amount of self-adhesive on the inner wall of the barrel and the inner wall of the barrel cover; comparative examples 1-2 groups were coated with the same amounts of the glue of comparative examples 1-2 on the inner wall of the tub and the inner wall of the tub cover, respectively; then, each group of barrels is filled with engine oil, the barrels are sealed by a cover, the weight m1 (g) of the barrels is weighed, the weight m2 (g) of the barrels is tested after the barrels are placed for 30 days at 50 ℃, the permeation quantity (g) =m1-m 2, and the average value of 3 experimental results in each group is taken as the permeation quantity measurement value; the smaller the measured value of the permeation quantity, the better the barrier property against engine oil. The results are shown in Table 1:
table 1 barrier test results table
As apparent from Table 1, the oil permeation amount of the barrels not coated with the adhesive was 8.31g, while the oil permeation amount of the barrels coated with the asphalt waterproofing membrane self-adhesives of examples 1 to 6 was 3.12 to 3.24g, and the oil permeation amount was greatly reduced, indicating that the asphalt waterproofing membrane self-adhesives of examples 1 to 6 had better oil barrier properties. The tub of comparative example 1 was coated with a gum containing no inorganic filler, and the oil penetration amount reached 5.76g, which was more than doubled with respect to the tub of example 1 group, 3.14, indicating that the inorganic filler in the self-adhesive composition plays a significant role in blocking oil penetration. The barrel coating of comparative example 2 was carried out by adding the tackifying resin at one time instead of adding the kneaded glue in two times, and the detection result was that the penetration amount of the machine oil was 4.04g, and also a good machine oil barrier property was exhibited, but the machine oil barrier property was lowered compared with example 1, which means that when the asphalt waterproofing membrane self-adhesive was prepared, the tackifying resin was added in two times, and once at kneading, the barrier property of the asphalt waterproofing membrane self-adhesive to the machine oil was better after kneading, which may be related to the crosslinking density of the tackifying resin in the asphalt waterproofing membrane self-adhesive, and the formed asphalt waterproofing membrane self-adhesive had a good crosslinking density, and the coating film showed that the compactness of the membrane was better, and the barrier property to the machine oil was increased.
(2) Peel strength test
The testing method comprises the following steps: the peel strength of the aluminum sheet before aging was measured according to 5.12.2 in GB/23441-2009 standard, and the peel strength of the aluminum sheet after aging was measured according to 5.16 and also according to 5.12.2. Wherein the asphalt coiled material is coated with the surface sizing agent as the prior art for comparison;
the face glue consists of the following components in percentage by weight: 0.3% of antioxidant, 24% of naphthenic oil, 3.5% of SBS 791, 30% of SIS 1126 22%, 19% of DCPD tree, 1% of terpene phenol resin and 0.2% of silane coupling agent.
Control group 1: a commercially available asphalt roll;
control group 2: coating a surface adhesive on a commercial asphalt coiled material;
group of examples: coating primer on the asphalt coiled material sold in the market, and then coating surface glue on the primer; wherein the primer is the asphalt waterproof coiled material self-adhesive of the examples 1-6;
comparative example group: coating primer on the asphalt coiled material sold in the market, and then coating surface glue on the primer; wherein the primer is the one of comparative examples 1-2.
The peel strength test results are shown in table 2:
table 2 results of the peel strength test of aluminum plate
From the test results of the peel strength of the aluminum plate in table 2, it can be seen that: the examples and the control group 2 can greatly improve the peel strength of the asphalt coiled material, and show good initial adhesion and adhesion. However, as can be seen from comparison of the example group and the control group 2, the self-adhesive of the asphalt waterproof coiled materials of the examples 1-6 is continuously coated on the basis of the surface adhesive coating, and the peeling strength is better than that of the self-adhesive of the asphalt waterproof coiled materials of the examples 1-6, which is only coated with the surface adhesive, so that the peeling strength of the asphalt waterproof coiled materials can be enhanced. From the aged data, the peel strength of the example group was reduced less after aging, and still maintained higher peel strength, between about 1.95 and 2.03, which is comparable to the values of control group 1 when it was not aged, indicating that the asphalt coil of the example group had better performance. Comparison of example 1 of the example group and the comparative example group may confirm that the solid filler in the adhesive plays an important role in resisting aging and improving peel strength, probably because the primer layer blocks the adverse effect of migration and diffusion of the hybrid small molecular substances such as waste engine oil and waste heat conducting oil in the asphalt layer, so that the adhesive property of the adhesive is not affected.
In conclusion, the asphalt waterproof coiled material self-adhesive disclosed by the invention has good adhesive property, and meanwhile, adverse effects caused by migration and diffusion of the impurity micromolecule substances such as waste engine oil and waste heat conducting oil in an asphalt layer can be avoided, so that the service life of the asphalt coiled material is prolonged.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
