Description

Technical Field

[0001] The invention relates to the technical field of waterproof coiled materials, in particular to a waterproof material for waterproof coiled materials. Background Art

[0002] Waterproof membrane is a building material with waterproof function, usually composed of one or more layers of materials. It blocks moisture, thus protecting the building and extending the building's protective life. According to the different synthetic raw materials, waterproof membrane can be divided into rubber-based, modified asphalt-based, polyvinyl chloride (PVC)-based, glass fiber-based and polymer materials. Among them, modified asphalt-based waterproof membrane accounts for a large share of the market, but with the gradual increase in environmental protection requirements, the advantages of polymer waterproof membrane are becoming increasingly prominent.

[0003] PVC waterproofing membrane is composed of PVC resin, plasticizer, stabilizer, etc. It has good water resistance, chemical resistance, UV resistance and high temperature resistance, but the strength of the material itself is low. In addition, the compatibility of additives with PVC is poor, and plasticizers are easy to migrate; polyethylene (HDPE) waterproofing membrane is suitable for high-pressure environments, but its own flame retardant effect is poor and its application range is small; ethylene propylene diene monomer (EPDM) waterproofing membrane has good elasticity, weather resistance, UV resistance and chemical resistance; thermoplastic polyolefin (TPO) waterproofing membrane is a waterproof material made of polyolefin polymers, which has good UV resistance, weather resistance and heat reflectivity. However, the use of the above materials requires the use of welding technology, including hot air welding and infrared welding, etc., to improve the sealing effect, but the construction is complicated. Therefore, self-adhesive waterproofing membranes have emerged, which do not require hot welding during construction, and are simple to construct and low in cost. However, self-adhesive waterproof membranes are easily affected by the construction environment during the construction process. As the temperature rises, the fluidity of the self-adhesive layer increases. When constructed in a low-temperature environment, the membrane shrinks, which increases the difficulty of construction. The waterproof membrane bonded during construction is also prone to reduced viscosity under the influence of the external ambient temperature, resulting in bulging and reduced peel strength.

[0004] To overcome the above problems, plasticizers, UV inhibitors and high-performance fillers are added to waterproof membranes, but these substances have poor compatibility with the polymer raw materials of waterproof membranes, and the above additives have poor dispersibility, which in turn reduces the performance of waterproof membranes and reduces the waterproof effect of waterproof membranes. In addition, the waterproof performance of waterproof membranes that have been used for a long time has declined, and the decline in performance cannot be directly observed with the naked eye.

[0005] Therefore, a waterproof material for waterproof membrane is proposed. Summary of the invention

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By using polyethylene TPO, alkenyl methyl siloxane, dithiol, benzoin dimethyl ether and potassium persulfate complex salt as basic components of a raw material for synthesizing a waterproof layer, adjusting their dosage to form a raw material containing a polysulfone polysilane structure and a TPO cross-linked structure, and adjusting the dosage of the raw material for the waterproof layer and the modified high-density polyethylene component, the waterproof roll material obtained by the waterproof raw material has good temperature resistance.

[0026] 2. By introducing hollow glass microspheres, the borosilicate glass contained therein can improve the heat resistance of the waterproofing membrane. By modifying its surface, alkaline hollow glass microspheres are obtained, and the alkalinity of the alkaline hollow glass microspheres is adjusted. Then, maleic anhydride is introduced into the alkaline hollow glass microspheres. The carboxyl group after the ring opening of maleic anhydride is neutralized with the alkalinity of the alkaline hollow glass microspheres, thereby introducing maleic anhydride into the alkaline hollow glass microspheres. Then, the unreacted carboxyl group in the maleic anhydride molecule is condensed with the amino group of KH550. The modified silane-maleic anhydride-hollow glass microspheres are mixed with maleic anhydride grafted high-density polyethylene. In the molten state, the hydroxyl groups in the silane-maleic anhydride-hollow glass microspheres react and cross-link with the maleic anhydride in the maleic anhydride grafted high-density polyethylene. At the same time, the dosage ratio of the anti-aging agent, the antioxidant, the aromatic oil, the PP wax and the leveling agent is controlled, and the obtained waterproofing membrane has further improved heat resistance.

[0027] 3. By adjusting the composition and proportion of p-phenylenediamine and organic mixed acid in the nanofiltration raw material 1, the surface of the sheet obtained from the waterproof outer layer raw material is treated, and then the nanofiltration raw material 1 and the post-treatment liquid are used for treatment, so that a layer of reverse osmosis nanofiltration membrane structure with a certain strength is formed between the waterproof outer layer and the microcapsule layer. After the external water passes through the waterproof outer layer, it is further blocked in the nanofiltration structure layer, and a small part of the water enters the microcapsule layer, thereby changing the color of the waterproof coiled material. The waterproof performance is improved, and the waterproof effect of the waterproof coiled material is more intuitive.

[0028] 4. By adjusting the amount of alkenylmethylsiloxane used to prepare the raw materials for the waterproof outer layer; by changing the method for preparing the raw materials for the microcapsule layer, wherein the amount ratio of MDI to quicklime, anhydrous ferrous sulfate and diethylenetriamine is adjusted, wherein MDI, on the one hand, forms a solidified urea-based compound when it comes into contact with water, and releases a large amount of heat at the same time; on the other hand, anhydrous ferrous sulfate plays a role as a color indicator in the waterproof coiled material, and turns light green when it comes into contact with water, and the change in color can directly reflect the water-resistant effect of its waterproof outer layer; in addition, quicklime releases heat when it comes into contact with water, and under the action of diethylenetriamine, MDI reacts with the hydroxyl group or part of the hydroxyl cage silane of the nanocellulose in the nanofiltration composite layer structure to form a compound containing an amide structure, and the cross-linked substance formed by the curing of the microcapsule layer forms a new protective layer again; at the same time, the molar ratio of polylactic acid and glycolic acid, the amount of hydroxyl cage silane, the reaction temperature and the particle size of the raw materials for the microcapsule layer are adjusted, thereby further improving the waterproof effect of the waterproof coiled material.

[0029] 5. By rationally selecting the type of fluorine-based acrylate in the raw material of the adhesive layer, the acrylate containing unsaturated double bonds is polymerized under the action of an initiator, and then the amount of diacetyl adipic acid dihydrazide added is adjusted, the type of acid is changed, and finally the amount of hydroxy cage silane is adjusted, thereby improving the waterproof effect of the adhesive layer in the waterproof membrane and the bonding peel strength to cement.

[0060] The waterproof roll prepared by the waterproof material prepared by Examples 1-10 of the present invention has a tensile strength of 67.8-74.0 N / cm and 31.1-37.6 N / cm at 23°C and 60°C, respectively, and a tensile elongation at break of 450%-540% and 370%-430% at 23°C and -20°C, respectively, as shown in Table 2. By using TPO, alkenyl methyl siloxane, dithiol and benzoin dimethyl ether as starting reaction raw materials, wherein the sulfur atom in the dithiol simultaneously performs nucleophilic attack on the carbon atom of the vinyl group and the carbon atom on the unsaturated double bond in the alkenyl methyl siloxane, and forms a thioether bond, and benzoin dimethyl ether, as a compound containing a benzene ring and an ether group, cross-links with the thioether bond to promote the formation of the thioether bond and the cross-linking structure, and then promotes the generation of free radicals under the action of potassium persulfate composite salt, thereby obtaining a raw material for a waterproof layer containing a polysulfone polysilane structure and TPO cross-linking, in which the polysulfone and siloxane structures are alternately connected. In Examples 1-3, the type of alkenylmethylsiloxane was changed, and the waterproofing membrane obtained by Example 3 using 1,7-divinyl-octamethyltetrasiloxane had the highest tensile strength and elongation at break at different temperatures. As the amount of silicon atoms introduced increased, the proportion of methylsiloxane structure in the raw material of the waterproof layer increased, the tensile strength decrease value at 60°C was low, and the elongation at break was high at -20°C. The results of Examples 3 and 4 show that the temperature resistance decreases when the amount of alkenylmethylsiloxane is reduced. The results of Examples 3, 5 and 6 show that by changing the type and amount of dithiols, the sulfur in the dithiols eventually forms a sulfide structure. Example 3 uses 1,2-benzenedithiol with high tensile strength and elongation at break at 230°C, high tensile strength at 60°C, and the alternating benzene ring structure improves the temperature resistance of the waterproofing membrane. The results of Examples 3 and 7 show that increasing the amount of 1,2-benzenedithiol increases the tensile strength at 60°C, and the elongation at break at -20°C decreases. As the polysulfone and benzene ring structures formed increase, the heat resistance effect increases, but the brittleness at low temperatures also increases. The results of Examples 7-10 show that the heat resistance effect is improved by reasonably adjusting the amount of waterproof layer precursor, THF, potassium persulfate composite salt and deionized water; the heat resistance effect is further improved by mixing the waterproof layer raw material with modified high-density polyethylene in a suitable proportion. Comparative Examples 1 and 2 do not add modified high-density polyethylene and waterproof layer raw material, respectively, and the tensile strength and break productivity are lower than those of the examples, and the heat resistance performance is reduced.

[0074] Different from Example 9, no PP wax was added.

[0075] Embodiment 21

[0076] The waterproof outer layer materials of Examples 12-20 and Comparative Examples 3-6 were used to prepare waterproof rolls, and the temperature resistance performance was tested. The specific preparation method and test method were carried out with reference to Example 11, and the final test results are shown in Tables 4 and Figure 2 shown.

[0077] Table 4 Elongation at break test results of Example 9, Examples 12-20 and Comparative Examples 3-7

[0078]

[0079] The waterproof outer layer raw materials prepared from Examples 9, 12-20 and Comparative Examples 3-7 of the present invention are further used to prepare waterproof rolls, such as Figure 2As shown in Table 4, the tensile strength at 23°C and 60°C is 71.9-74.8N / cm and 35.1-38.5N / cm, respectively. As shown in Table 4, the elongation at break at 23°C and -20°C is 490%-550% and 390%-450%, respectively. The results of Examples 9, 12-14 show that as the alkalinity of the alkaline hollow glass microspheres increases, the tensile strength at 23°C and 60°C gradually increases, and the elongation at break at 23°C and -20°C also shows a trend of gradually increasing. This is because the alkalinity increases, the content of reactive hydroxyl groups in the system increases, and the hydroxyl groups react with the introduced maleic anhydride and KH550 on the one hand, and esterify with maleic anhydride in polyethylene on the other hand, thereby improving the crosslinking degree of the system; the results of Comparative Example 3 show that when the alkalinity is low, the tensile strength and elongation at break at 23°C are not significantly changed compared with Example 9, but the performance at 60°C and -20°C is reduced. The results of Examples 12, 15 and 16 show that the hollow glass spheres are modified by introducing KH550, and the heat resistance gradually improves as its dosage increases. The results of Examples 16-18 show that as the temperature of the melt mixing increases, the tensile strength at 60°C and the elongation at break at -20°C both show a trend of first decreasing and then increasing. At the same time, the results of Comparative Example 4 further prove that the introduction of KH550 into the hollow glass microspheres has the effect of improving the heat resistance of the waterproof roll; controlling the temperature within a lower range has a protective effect on the raw materials of the material. The results of Examples 18-20 show that the dosage ratio of the anti-aging agent, antioxidant, aromatic oil, PP wax and leveling agent is adjusted, wherein the aromatic oil plays a role in plasticizing the waterproof roll and improving the ductility of the roll, and the use of the leveling agent improves the consistency of the raw material mixing; the PP wax mainly plays a role in improving the thermal stability of the roll, the anti-aging agent and antioxidant improve the stability of the roll in use, and the coordinated use of multiple substances further improves the heat resistance of the waterproof roll. The results of Comparative Examples 5-7 show that without adding antioxidants, aromatic oils or PP wax, the tensile strength and elongation at break at 23°C do not decrease significantly, but the tensile strength at 60°C and the elongation at break at -20°C are both lower than those in Example 9.

[0080] Examples 22-29

[0081] Different from Example 19, the dosage of nanofiltration raw material 1 and nanofiltration raw material 2 is changed, as shown in Table 5.

[0082] p-phenylenediamine, triethylamine, organic mixed acid and deionized water are mixed to obtain nanofiltration raw material 1, wherein the mass percentage of p-phenylenediamine is 3.2%, the mass percentage of triethylamine is 1.7%, and the mass percentage of organic mixed acid is 3.9%. Trimethylolyl chloride and 1-hexene are mixed to obtain nanofiltration raw material 2, wherein the mass percentage of trimethylolyl chloride is 5.5%.

[0083] The nanocellulose and triethylamine are dissolved in deionized water to obtain a post-treatment solution, wherein the mass percentage of the nanocellulose is 2% and the mass percentage of the triethylamine is 1.7%.

[0084] Comparative Example 8

[0085] Different from Example 19, only fumaric acid was added.

[0086] Comparative Example 9

[0087] Different from Example 19, only polyacrylic acid was added.

[0088] Comparative Example 10

[0089] In contrast to Example 19, only polystyrene sulfonic acid was added.

[0090] Comparative Example 11

[0091] Different from Example 19, no nanocellulose was added.

[0092] Embodiment 30

[0093] The nanofiltration raw material 1, nanofiltration raw material 2 and post-treatment liquid obtained in Examples 19, 22-29 and Comparative Examples 8-11 were used to treat waterproof rolls, and the waterproof performance of the obtained waterproof rolls was tested. The waterproof performance test was carried out with reference to the physical properties of the composite sheet in GB T 18173.1-2012 "Polymer Waterproof Materials Part 1: Sheets", and the final test results are shown in Table 5.

[0094] Table 5 Changes in the amount of nanofiltration raw material 1, nanofiltration raw material 2 and nanocellulose

[0095]

[0096] The results in Table 5 show that the waterproof roll prepared by the present invention has an effective time of 60-120 minutes for the first waterproof outer layer to block water. After the waterproof outer layer is treated with nanofiltration raw material 1, the amino group in the p-phenylenediamine structure is connected with the maleic anhydride in the waterproof outer layer raw material, thereby being closely combined with the waterproof outer layer, and some organic acids react with the amino groups of p-phenylenediamine, and then nanofiltration raw material 2 is added, and trimeryl chloride is reacted with the unreacted amino group in p-phenylenediamine to obtain a polyamide structure, and the hydroxyl group of the nanocellulose in the post-treatment liquid replaces the chlorine element. The triethylamine added therein plays a role in neutralizing the pH of the system, and 1-hexene can cross-link with the permeable structure or react with the unsaturated double bonds in the TPO or high-density polyethylene in the waterproof outer layer raw material, thereby improving the percolation effect on water and the strength of the nanofiltration structure, and the cross-linked nanocellulose crystals have a certain absorption and storage effect on water.

[0097] In Examples 19, 22 and 23, as the mass percentage of p-phenylenediamine in the nanofiltration raw material 1 increases, the 0.3MPa single layer water permeability discoloration time gradually increases. This is because the benzene ring structure introduced therein improves the mechanical strength of the nanofiltration structure membrane layer, thereby increasing the waterproof time. The results of Examples 23-25 ​​show that the type of organic mixed acid is adjusted, and the discoloration time under the conditions of Example 24 is the longest. After the polystyrene sulfonic acid reacts, the permeability of the membrane to water is reduced, the water flux of the membrane is improved, and the waterproof effect is the best. The results of Examples 24 and 26 show that by adjusting the dosage ratio of the organic mixed acid, the time for water permeability to discolor is increased; the mixed use of organic acids synergistically improves the waterproof effect. In Comparative Examples 8-10, only one organic acid is added, and the time for discoloration to appear is shortened. The results of Examples 26-28 show that as the mass percentage of trimerephthaloyl chloride increases, the time for discoloration to occur increases first and then decreases. By controlling the dosage within the range shown in the examples, the water impact strength of the nanofiltration structure is improved, and the process of the reaction between nanocellulose and trimerephthaloyl chloride is also increased. The time for discoloration to occur increases, and the waterproof performance is improved. The results of Examples 28 and 29 show that the waterproof performance is good when the content of nanocellulose is adjusted; in Comparative Example 11, nanocellulose is not added, and the waterproof effect decreases. By introducing a nanofiltration structure into the waterproof coiled material, the waterproof performance of the waterproof coiled material is improved.

[0098] Examples 31-43

[0099] Different from Example 29, the preparation method of the raw materials of the microcapsule layer and the amount of alkenylmethylsiloxane in the waterproof layer are changed, as shown in Table 6. The four substances in Table 6 are MDI, quicklime, anhydrous ferrous sulfate and diethylenetriamine.

[0100] Table 6 Preparation method of microcapsule layer raw materials and amount of alkenylmethylsiloxane used

[0101]

[0102] Comparative Example 12

[0103] Different from Example 29, no microcapsule layer raw material was added.

[0104] Embodiment 44

[0105] The microcapsule layer raw materials, waterproof outer layer raw materials and other components prepared in Examples 29, 31-43 and Comparative Example 12 were used to prepare waterproof coiled materials, and the obtained waterproof coiled materials were tested for waterproof performance, wherein the test of single-layer water permeability time was carried out with reference to Example 30, and the test of watertightness time was carried out with reference to the physical properties of composite sheets in GB T 18173.1-2012 "Polymer Waterproof Materials Part 1: Sheets", and the final test results are shown in Table 7.

[0106] Table 7 Waterproof test results of waterproof membranes obtained in Examples 29, 31-45 and Comparative Example 12

[0107]

[0108] The waterproof coiled material prepared by the present invention has a color change time of 115-155 minutes for a single layer of 0.3MPa waterproof coiled material, and a water permeability time of 130-185 minutes for a 0.3Mpa waterproof coiled material. On the one hand, MDI forms a solidified urea-based compound when it meets water, and releases a large amount of heat at the same time; on the other hand, anhydrous ferrous sulfate plays a role of indicating color in the waterproof coiled material, and turns light green when it meets water (color observation is performed after the section is cut), and the water resistance effect of its waterproof outer layer can be directly reflected by the color change; on the other hand, quicklime releases heat when it meets water, and under the action of diethylenetriamine, MDI reacts with the hydroxyl group or part of the hydroxyl cage silane of the nanocellulose in the nanofiltration structure to form a compound containing an amide structure, and the cross-linked substance formed by the curing of the microcapsule layer forms a new protective layer again; the molar ratio of polylactic acid and glycolic acid is adjusted, and in the process of heating and pressing the waterproof coiled material, the free carboxyl group reacts with the hydroxyl group of the hydroxyl cage silane to esterify, thereby introducing a strong waterproof compound into the microcapsule layer. The results of Examples 29, 31 and 32 show that with the increase in the amount of alkenylmethylsiloxane, the time for the monolayer to change color after water permeability increases first and then decreases, and the water permeability time of the waterproof roll tends to remain unchanged after the increase. The adjustment of alkenylmethylsiloxane in the waterproof outer layer has an increasing effect on the waterproof effect of the outer layer, but excessive dosage leads to increased flexibility and reduced water pressure resistance. The water permeability time of the waterproof roll is related to the waterproof effect of the nanofiltration composite layer, microcapsule layer, waterproof inner layer and adhesive layer, so the waterproof time tends to remain unchanged. The results of Examples 31, 33 and 34 show that by reasonably adjusting the amount of MDI and quicklime in the four substances, the waterproof effect is improved. The results of Examples 34-36 show that by reasonably adjusting the amount of anhydrous ferrous sulfate and diethylenetriamine, the color development effect of ferrous sulfate under the conditions of Example 34 is the best, and the waterproof effect is also the best. The results of Examples 34, 37 and 38 show that by adjusting the molar ratio of polylactic acid and glycolic acid, glycolic acid and hydroxyl cage-shaped silane react more completely, thereby increasing the time for discoloration of the monolayer permeability and the water permeability time of the waterproof roll. The results of Examples 38 and 39 show that the waterproof effect increases with the increase in the amount of hydroxyl cage-shaped silane. The results of Examples 39-41 show that with the increase in the reaction temperature, the waterproof effect first increases and then decreases, and the waterproof effect under the conditions of Example 40 is the best. The results of Examples 40, 42 and 43 show that the waterproof effect is best when the average particle size of the raw material of the microcapsule layer of Example 40 is 450nm. This is because water enters the microcapsule layer through the nanofiltration composite layer, and the average particle size of the raw material of the microcapsule layer is too low, then the water absorption effect increases, and the particle size is too high, which is not conducive to the improvement of the waterproof effect. After water enters the microcapsule layer through the nanofiltration composite layer, the components undergo cross-linking reactions to form a new cured protective layer. Comparative Example 12 does not add microcapsule layer raw materials. Compared with the comparative example, the discoloration time of the 0.3MPa single-layer water permeability and the water permeability time of the 0.3Mpa waterproof membrane are reduced.

[0109] Examples 45-52

[0110] Different from Example 40, the preparation method of the adhesive layer raw material is changed, as shown in Table 8.

[0111] Table 8 Preparation method of adhesive layer raw materials

[0112]

[0113] Embodiment 53

[0114] The waterproof membranes obtained in Examples 40 and 45-52 were tested for waterproof performance. The waterproof membranes were adhered to the surface of uncured concrete and tested for water impermeability under a water pressure of 0.3 MPa after covering for 72 hours. The examples were adhered to uncured concrete and cured for 72 hours, then immersed in water, and the 180° peel strength was tested after immersion for 48 hours. The final test results are shown in Table 8.

[0115] The peel strength of the waterproof roll prepared by the present invention after immersion in water is 2.5-4.0 N / mm. The unsaturated double bonds in methyl methacrylate, ethyl acrylate, tripropylene glycol diacrylate, diacetone acrylamide and 2,2,3,3,4,4,4-heptafluorobutyl acrylate are polymerized, and the introduced fluorine atoms improve the waterproof effect of the waterproof material; the diacetyl adipic acid dihydrazide added thereafter is cross-linked and polymerized again with the components in the polymerization liquid, and the added acid reacts with the unreacted amino groups in the diacetyl adipic acid dihydrazide, and partially reacts with the hydroxyl groups of the hydroxy cage silane for esterification, thereby improving the waterproof effect. The results of Examples 40, 45 and 46 show that the waterproof roll has the best waterproof effect under the conditions of Example 46, which is due to the increase in the introduced fluorine atoms and the increase in the resistance to water. The results of Examples 46-48 show that the waterproof effect is best when the amount of diacetyl adipic acid dihydrazide is controlled within a reasonable range. The results of Examples 47, 49 and 50 show that the peel strength is the highest when oxalic acid is used for the reaction, because oxalic acid has the strongest binding force with the substances in cement, so it is not easy to peel off; while when citric acid is used, the hydroxyl groups at both ends of its molecule connect diacetyl adipic acid dihydrazide with hydroxy cage silane. The results of Examples 49, 51 and 52 show that as the amount of hydroxy cage silane used increases, the water-blocking effect of the waterproofing membrane is enhanced.

[0116] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
