Detailed Description

The following description is only intended to disclose the invention so as to enable any person skilled in the art to practice the invention. The embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other arrangements without departing from the spirit and scope of the invention.

As shown in figure 1, the utility model provides an ultraviolet curing hose for the non-excavation restoration of road pipeline. The ultraviolet curing hose comprises a curing resin layer 1, a glass fiber fabric layer 2, a one-way breathable impermeable layer 3 and an outer film layer 4.

The glass fiber fabric layer 2 is made of a material resistant to municipal sewage. The glass fiber fabric layer 2 is injected into the cured resin layer 1 during construction and is combined into a whole.

The unidirectional air-permeable barrier layer 3 comprises a reinforcing layer 31 and unidirectional airfelt 32, the unidirectional airfelt 32 being adjacent to the fiberglass fabric layer 2. The unidirectional airfelt 32 is made of a non-woven fabric material, and specifically, the unidirectional airfelt 32 is a layered body formed by mixing and co-extruding a PP (polypropylene) material and a PE (polyethylene) material. As can be seen from the repeated production comparison tests, compared with the unidirectional airfelt 32 made of a single material (for example, a single PP material or a single PE material), the unidirectional airfelt 32 made of a mixture of PP and PE materials by co-extrusion has a significantly reduced number of bubbles formed and a reduced porosity, and the specific data table of the test results is shown in table 1 below. The one-way air-permeable felt 32 can play a role in seepage prevention, the effect of improving reverse entering of bubbles is improved, the cured lining layer is more compact, the strength is improved, and meanwhile the service life of the product is prolonged.

TABLE 1

Optionally, the single layer of unidirectional airfelt 32 has a weight of 35 g. Through many times of repeated production tests, when the construction is injected into the cured resin layer 1, the outside air most easily stops at the one-way air-permeable felt 32 layer, the weight of the one-way air-permeable felt 32 is reduced from 45 grams to 35 grams, through the test, the problem that the bubbles reversely enter can be obviously improved by the one-way air-permeable felt 32, the cured inner liner layer is more compact, the strength is improved, and meanwhile the service life of the product is prolonged.

The outer film layer 4 is a yellow anti-puncture and anti-ultraviolet film. The reinforcing layer 31 is located between the unidirectional airfelt 32 and the outer film layer 4.

Optionally, the reinforcement layer is 200um thick. Through production tests, the thickness of the reinforcing layer 31 is increased from 100um to 200um, and the tensile strength and the puncture resistance strength of the whole ultraviolet curing hose are increased.

The ultraviolet curing hose comprises a high-temperature-resistant anti-skidding inner layer 5, wherein the high-temperature-resistant anti-skidding inner layer 5 and the one-way breathable felt 32 are respectively positioned on two opposite sides of the glass fiber fabric layer 2.

Ultraviolet curing hose is when the construction, at first need with the inner wall of old pipeline is fixed in the laminating of ultraviolet curing hose, wherein laminates with rete 4 orientation and the direction of the old pipeline inner wall of contact laminating, pours into cured resin layer 1 to containing fine fabric layer 2 of glass again after the laminating is good for cured resin layer 1 and fine fabric layer 2 joint as an organic whole. And finally, peeling off the high-temperature-resistant anti-skidding inner layer 5, and irradiating the ultraviolet curing hose by adopting ultraviolet light to cure the curing resin layer 1, so that the ultraviolet curing hose is firmly and tightly adhered to the inner wall of the old pipeline.

The utility model discloses a set up one-way ventilative barrier layer 3, can pour into the air admission in the effective separation external environment of in-process on solidification resin layer 1 into when the construction the inside of ultraviolet curing hose to avoid forming in the ultraviolet curing hose and remain the bubble and cause the cavity defect. Furthermore, the thickness of the reinforcing layer 31 is increased to 200um, while the thickness of the unidirectional airfelt 32 is reduced, and the weight of the unidirectional airfelt 32 is only 35g, so that on one hand, the tensile strength and the puncture resistance are improved through the increased thickness of the reinforcing layer, and on the other hand, the unidirectional airfelt is made of PP and PE materials through mixing and co-extrusion, so that the strength of the unidirectional airfelt can be increased to compensate for the strength reduction caused by the reduced thickness.
