Description

Film, base film, waterproof roll and application

Technical Field

The invention relates to the technical field of waterproof coiled materials, in particular to a film, a base film, a waterproof coiled material and application.

Background

The waterproof roll is a waterproof product prepared by impregnating asphalt or polymer waterproof materials on a base, and is provided for downstream customers in the form of a roll. The water-proof and water-proof composite material is mainly used for building roofs, walls, highways, tunnels, refuse landfills and the like, and is a main barrier for ensuring that buildings and structures prevent rainwater invasion and water permeation such as underground water. The influence of the performance of the waterproof material on the waterproof engineering is great.

The existing waterproof coiled material has various defects. For example, in the prior art, modified asphalt is used as a main waterproof layer, a non-woven fabric is added in the middle of the waterproof roll material to serve as a base layer of a tire, and the modified asphalt has good waterproof performance as the main waterproof layer, but is poor in extensibility, easy to tear and short in service life, and a polyester non-woven fabric layer has no waterproof effect. In addition, for example, a waterproof roll using a polyester film (PET) as a base layer has an increased waterproof ability, but has a very poor elongation. The common strong cross membrane of the surface layer of the waterproof roll has poor thermal dimensional stability and high expansion rate, so that the waterproof roll is easy to lap and fail; the elongation at break is small, the coiled material is easy to break, and water leakage is easy to cause. The strong cross membrane adopts two layers of membranes to be compounded together, so that firstly, the cost of material consumption glue is about 0.14 yuan per square meter; and delamination exists, namely the two layers are not firmly bonded, and the delamination is waste. Ordinary polyethylene film (PE) has high elongation, but has poor thermal dimensional stability, high elasticity and poor heat resistance, and cannot be applied to waterproof coiled materials. High Density Polyethylene (HDPE) is a thermoplastic resin with High crystallinity and non-polarity, and a common HDPE common mask self-adhesive waterproof coiled material has many advantages of underground water resistance, but has low tensile strength, poor dimensional stability and poor weather resistance.

The polyolefin waterproof substrate layer mentioned in patent application No. CN201910118738.0 has good low temperature bending property and good waterproof property, but has poor thermal stability and easy edge curl.

Therefore, aiming at the problems of edge rolling, delamination between films, poor dimensional stability, small elongation, non-aging resistance and the like of the existing waterproof film layer, the people in the field are always puzzled by how to obtain the waterproof roll material which has the advantages of high elongation, tear resistance, aging resistance, good dimensional stability, difficult shrinkage deformation, excellent waterproof performance, non-rolling performance and non-delamination performance.

Examples 1 to 18

The finished films 1-18 prepared by the applicant are detected by different detection means in the prior art according to corresponding national standards to obtain the component proportions in the following table.

TABLE 1 film 1-6 ingredient Table

TABLE 2 film 7-12 ingredients Table

TABLE 3 film 13-18 ingredients Table

Note: because of different detection means and precision, the detected components are different, and as the detection means is improved with the passage of time, part of the components can be further detected, and the amount of part of the components can also be changed.

Example 19

The performance of the films 1-18 is measured according to the measuring method and requirements specified in GB/T18840-2018 Foundation for asphalt waterproofing coiled material.

The standard specifies the indexes: the tension (N/50 mm) is more than or equal to 200 in the longitudinal direction and the transverse direction; the elongation at break (%) is not less than 160 in the longitudinal direction and the transverse direction; the relative indexes of thermal dimensional stability (90 ℃, 24h and percent), longitudinal and transverse directions, the elongation is less than or equal to 3.0, and the shortening is less than or equal to 3.0.

Film 1-18 Performance test results:

the tension (N/50 mm) is more than or equal to 300 in the longitudinal direction and more than or equal to 250 in the transverse direction; the tensile force (N/50 mm) measured on a part of the film is greater than or equal to 330 in the longitudinal direction and greater than or equal to 280 in the transverse direction.

The elongation at break (%) is more than or equal to 300 in the longitudinal direction and more than or equal to 300 in the transverse direction, and part of the film can reach more than or equal to 380 in the longitudinal direction and more than or equal to 380 in the transverse direction;

the indexes (90 ℃, 24h and percent) related to the thermal dimensional stability are less than or equal to 0.6 in the longitudinal direction and less than or equal to 0.6 in the transverse direction, and partial films can reach less than or equal to 0.3 in the longitudinal direction and less than or equal to 0.3 in the transverse direction.

The thickness of the detected films 1-18 is below 0.4mm, wherein, except the films No. 11 and No. 18, the thickness of the single layer of the other films is below 0.2 mm.

The single-layer surface film is thinner, so that better flatness is brought, the thickness uniformity is increased, the laminating degree of a single film layer or the laminating degree of the single film layer and other film layers is better, and the application is wider.

The films of the invention were compared with commonly used strong crossed films purchased on the market:

1. physical property comparison: the elongation at break of the film is more than or equal to 300 longitudinally and more than or equal to 300 transversely, the elongation at break of the commercially available strong cross film is more than or equal to 200 longitudinally and more than or equal to 200 transversely; the maximum tensile value and the tearing strength of the film are all larger than those of the commercially available strong film.

2. Thermal dimensional stability, table below:

TABLE 3

Under the same condition of 90 ℃ for 24h	Film of the invention	Strong cross membrane
			Transverse direction (%)	≤0.6	2.8
Longitudinal direction (%)	≤0.6	3.2

As shown in the table, the index relating to the thermal dimensional stability of the film is only 1/5 for the strong crossed film, so that the thermal dimensional stability of the film is better, and the dimensional stability is the most important index in the wet-laid waterproof roll.

3. The edge of the strong cross membrane is warped at normal temperature, and 1/4 is warped at the edge of the strong cross membrane used as a wet-laid coiled material after 2 hours at 55 ℃, so that the thin film does not have the defect.

The strong crossed film has the problem of edge warping due to incomplete release of tensile internal stress, the edge warping still exists after the strong crossed film is manufactured into a finished product, the coiled material fails to be bonded and leaks water in the use process, and the problem of small elongation at break exists if the strong crossed film is laminated after being stretched. These two conflicting problems found in strong crossed films are well solved in the films of the present invention because they have both good dimensional stability and a high elongation at break.

In conclusion, the film of the present invention has significant advantages over the prior art strong crossed films, such as low elongation, high water resistance and low elongation of the polyester nonwoven fabric, although the conventional tire base fabric and tire base film have water resistance. Other film layers which can be used as a base film also have the problems of rolling, lifting, edge warping and the like, but the film disclosed by the invention has good dimensional stability and higher elongation at break, and all the known problems existing in other base films at present can be solved by using the film disclosed by the invention.

Example 20

The films obtained in examples 1-18 were prepared into base films 1-18, which included a film layer and a reinforcing layer. The base film comprises at least one layer of the film of the invention and the stiffening layer comprises at least longitudinal stiffening ribs, as shown in figure 1, the arrows indicating the longitudinal direction.

In other embodiments, the reinforcing layer of the present invention may include longitudinal ribs and transverse ribs, as shown in FIG. 2. In other embodiments, the reinforcing layer of the present invention may further include diagonal reinforcing ribs.

The dashed lines in the figures are merely for showing that the spatial positions of the ribs and the film are not on the same plane, and are of a two-layer structure, and do not represent that the ribs are not connected, and in fact, the ribs of the present invention are preferably connected into a whole.

The reinforcing layer can be made of the existing materials, such as fiber mesh cloth or fiber non-woven fabric, and the fiber mesh cloth can be selected from glass fiber mesh cloth, polyester fiber mesh cloth, polypropylene fiber mesh cloth and the like; the fiber nonwoven fabric may be selected from glass fiber nonwoven fabric, polyester fiber nonwoven fabric, polypropylene fiber nonwoven fabric, and the like.

The film and the reinforcing rib of the present invention can be compounded by conventional methods, such as gluing.

The ribs of the present invention that are laminated to the film are preferably longitudinal ribs or comprise a combination of longitudinal ribs. Because in the existing common preparation method of the conventional coiled material, the base film is longitudinally pulled to lay other substances such as asphalt, heating may be involved in the processing process, and the longitudinal reinforcing ribs can effectively enhance the tolerance of the base film, especially under the condition of heating, the loss of the film is reduced, and the cost is greatly saved.

Example 21

The films 1 to 18 obtained in examples 1 to 18 were prepared into a waterproof roll. The waterproof roll comprises a film and an asphalt layer positioned on at least one side of the film.

The base films 1 to 18 obtained in example 20 were prepared into a waterproof roll. The waterproof roll comprises a base film and an asphalt layer positioned on at least one side of the base film.

The other side of the asphalt layer is the other surface of the asphalt layer which is not contacted with the base film.

The asphalt layer can be SBS modified asphalt layer, a glue layer made of asphalt, plasticizing oil, SBS, particles and talcum powder, a glue layer made of purchased commercial asphalt, or an asphalt layer made by the method disclosed in other patents. In other embodiments the roll of waterproofing material may comprise a base film and an asphalt layer on both sides of the base film.

The laying of the asphalt layer or the self-adhesive asphalt layer can be carried out in two ways, namely, a base film is drawn, and the laying of the asphalt or the self-adhesive asphalt is carried out in the process of advancing the base film, wherein the advancing direction of the base film is the direction indicated by an arrow in the drawing, and the direction is defined as a longitudinal direction in the invention; one is that when the basement membrane is static, asphalt or self-adhesive asphalt is piled on the basement membrane and is flattened. In the first laying mode, the base film compounded with the longitudinal reinforcing ribs has great advantages, the loss of the film is greatly reduced, and the production cost is greatly reduced.

The detection shows that the tearing strength of the ejector rod of the waterproof coiled material prepared by using the base film as the base is more than or equal to 70N, and the tearing strength of the ejector rod of the waterproof coiled material prepared by using the strong cross film as the base is more than or equal to 60N, so that the base film has better performance.
