Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waterproof materials, in particular to a self-adhesive polymer modified asphalt waterproof material and a preparation method and application thereof. BACKGROUND

[0002] Self-adhesive polymer modified asphalt waterproof coiled material (referred to as waterproof coiled material) has been widely used in the field of building waterproofing due to its convenient construction and good adhesion. It can quickly bond with the base layer and effectively prevent liquid water and water vapor penetration, providing reliable waterproof protection for buildings. However, the self-adhesive polymer modified asphalt waterproof coiled material on the market still has some shortcomings. From the aspect of material performance, the tensile and tear resistance of some products are poor, which can easily deform and tear during transportation or construction, affecting the waterproof effect. At the same time, its weather resistance needs to be improved. Long-term exposure to outdoor environments, affected by factors such as ultraviolet light and temperature changes, can easily cause aging and cracking, leading to failure of the waterproof layer. In addition, the adhesion of self-adhesive polymer asphalt is not stable at different temperatures, which decreases at low temperatures and may soften and flow at high temperatures, causing the coiled material to slide and peel off.

[0003] With the continuous development of the construction industry, higher requirements are placed on the performance, environmental friendliness, and construction convenience of waterproof materials. In order to meet market demand and improve the quality and applicability of self-adhesive polymer modified asphalt waterproof coiled material, it is of great practical significance to develop a self-adhesive polymer modified asphalt waterproof material with better performance.

The composite modification of illite and phthalate ester through the synergistic mechanism of "rigid skeleton support-flexible chain segment plasticization" not only utilizes the layered structure of illite to improve the mechanical strength and weather resistance, but also optimizes the flexibility and adhesion through the plasticizing effect of phthalate ester, so that the self-adhesive asphalt waterproof material achieves balance in key properties such as high and low temperature, adhesion and aging resistance.

[0056] In a fourth aspect, the present application provides a preparation method of the self-adhesive polymer modified asphalt waterproof material, which comprises the following steps:

[0057] The self-adhesive polymer modified asphalt waterproof material is coated on the upper and lower surfaces of the base layer to form the upper modified asphalt waterproof layer and the lower modified asphalt waterproof layer, respectively, to obtain a waterproof material semi-product;

[0058] The release film and the anti-adhesion film are respectively coated on the upper and lower surfaces of the waterproof material semi-product to obtain the self-adhesive polymer modified asphalt waterproof material.

[0059] The present application has the following beneficial effects:

[0060] POE has good elasticity and ductility, can form an interpenetrating network structure with asphalt, and the elastic segments of POE can enhance the cohesion of asphalt, so that the waterproof material is not prone to cracking at low temperature and is not prone to flowing at high temperature, thereby improving its tensile strength and elongation at break; the alternating structure of the crystalline region and the amorphous region of POE can inhibit the thermal motion of asphalt molecules, reduce the tendency of high-temperature creep, and improve the anti-deformation ability of the waterproof material; the molecular chain of POE does not contain double bonds, and has excellent weather resistance; POE has good compatibility with saturated components and aromatic components in asphalt, and can be uniformly dispersed by melt blending.

[0061] SBR, as a rubber modifier, has a double bond structure that gives the material high elasticity, and is not prone to cracking due to sudden temperature drop during construction in cold regions, and has excellent low-temperature performance; after being stretched by external force, the rubber network of SBR can quickly recover, reducing permanent deformation under long-term load and having good elastic recovery ability; the polar groups (such as benzene ring and vinyl group) of SBR can enhance the adhesion to the base layer and improve the peel strength; the micro-network structure of SBR can increase the surface adhesion of the waterproof material, allowing it to quickly bond after the release film is removed during construction, reducing slippage; SBR has a low price and can partially replace rubber modifiers, reducing costs while ensuring performance, making it suitable for large-scale engineering applications.

[0062] Gumarol resin is a low molecular weight thermoplastic resin that can improve the rheological properties of asphalt, and has viscosity and softening point control functions, which can increase the cohesion of asphalt at room temperature, reduce the flowability of self-adhesive waterproof materials, and reduce the melt viscosity when heated, facilitating coating construction; the polar structure and low molecular weight characteristics of gumarol resin can optimize the viscoelastic properties and improve the tackiness; as a tackifying resin, gumarol can fill the interfacial gap between POE and SBR, reduce phase separation, and improve the overall compatibility of the modifier; the aromatic ring structure of gumarol resin has certain antioxidant properties, which can slow down the aging rate of asphalt.

[0063] As a layered silicate mineral, the sheet structure of illite can form a "skeleton-network" composite system with asphalt by physical filling. The rigid structure of illite sheet can inhibit the thermal motion of asphalt molecules, and the van der Waals force between the sheets can enhance the cohesion at low temperature, thereby reducing the risk of cracking and improving the anti-deformation ability and tensile strength and modulus of the waterproof material. The layered surface of illite has a negative charge and a certain polarity, which can form physical adsorption with the polar components (such as asphaltene) in asphalt, thereby enhancing the interfacial adhesion. The stacking structure of illite sheet can hinder the creep of asphalt molecules, so that the waterproof material has good water resistance and long-term tackiness. The layered shielding effect of illite can delay the erosion of external factors on asphalt, and the sheet structure can reflect ultraviolet rays, while the water molecules between the layers can inhibit the penetration of oxygen molecules, thereby improving the aging resistance and impermeability of the waterproof material.

[0064] The molecular chain of phthalate can insert between asphalt molecules, weaken the intermolecular force, reduce the melt viscosity of asphalt, and improve the low-temperature ductility and workability. The polar ester group of phthalate can form hydrogen bonding with asphalt and illite, thereby reducing the surface hardness of the waterproof material and improving the immediate adhesion after the release of the release film. Phthalate can reduce the agglomeration of illite sheets, making them more uniformly dispersed in asphalt, and improve the compatibility of multiple components. The ester group structure of phthalate has a certain hydrolysis resistance, which can complement the deficiency after being compounded with illite. DETAILED DESCRIPTION

[0153] Application Example

[0154] The self-adhesive polymer modified asphalt waterproof materials provided by Examples 1-11 and Comparative Examples 1-7 are respectively made into self-adhesive polymer modified asphalt waterproof rolls, which include, from top to bottom, a release film (PE film), an upper modified asphalt waterproof layer, a polyester base layer, a lower modified asphalt waterproof layer, and a release film (peelable silicone oil film). The thicknesses of the release film, the upper modified asphalt waterproof layer, the polyester base layer, the lower modified asphalt waterproof layer, and the release film are 0.03 mm, 0.9 mm, 1.5 mm, 0.9 mm, and 0.15 mm, respectively.

[0155] Both the upper modified asphalt waterproof layer and the lower modified asphalt waterproof layer are made of the self-adhesive polymer modified asphalt waterproof material.

[0156] The preparation method of the self-adhesive polymer modified asphalt waterproof roll includes the following steps:

[0157] S300, the self-adhesive polymer modified asphalt waterproof materials provided by examples 1-11 and comparative examples 1-7 are respectively coated on the upper and lower surfaces of the polyester base layer, to form an upper modified asphalt waterproof layer and a lower modified asphalt waterproof layer, to obtain a waterproof roll semi-finished product.

[0158] S400, the isolation film and the anti-adhesion film are respectively covered on the upper and lower surfaces of the waterproof roll semi-finished product, and then the product is cooled and rolled, to obtain a self-adhesive polymer modified asphalt waterproof roll.

[0159] The self-adhesive polymer modified asphalt waterproof roll prepared by using the self-adhesive polymer modified asphalt waterproof materials provided by examples 1-11 and comparative examples 1-7 in the application examples is subjected to relevant performance tests, and the results are shown in Table 1.

[0160] The low-temperature flexibility is determined according to GB / T 328.14-2007 "Test methods for building waterproof rolls Part 14: Test method for low-temperature flexibility of asphalt waterproof rolls". The peeling strength, tackiness and heat aging resistance are determined according to the test method for PY type rolls in GB 23441-2009 "Self-adhesive polymer modified asphalt waterproof roll". The heat aging treatment method refers to "5.16.2 PY type roll" thereof: the test piece is horizontally placed in a (70±2) ℃ oven for 7d±2h, and then taken out and placed at (23±2) ℃ for 24h.

[0161] Table 1: Performance test results of the waterproof roll

[0162]

[0163] As can be seen from Table 1, the waterproof roll provided by examples 1-4 has excellent comprehensive performance, the low-temperature flexibility is-39℃--36℃, the peeling strength between the roll and the roll is 1.47N / mm-1.64N / mm, the peeling strength between the roll and the aluminum plate is 2.13N / mm-2.52N / mm, the tackiness time is ≥200min, and the peeling strength reduction rate after heat aging is 9.1%-11.2%.

[0164] After the composition or amount of the softening oil is changed in examples 5-7, the comprehensive performance of the waterproof roll slightly decreases, and the decrease in the peeling strength is more obvious. After the composition or amount of the modifier is changed in examples 8-10, and the filler component is changed in example 11, the comprehensive performance of the waterproof roll decreases to different degrees. After the composition and amount of the modifier are changed in comparative examples 1-4, and the functional modified material is changed in comparative examples 5-7, the comprehensive performance of the waterproof roll greatly decreases.

[0165] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
