Furthermore, the present utility model may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not themselves indicate the relationship between the various embodiments and/or arrangements discussed.

The specific embodiment is as follows:

Referring to fig. 1, the utility model provides a novel pipe root waterproof prefabricated member, which is specifically as follows:

Preform structure: the waterproof preform comprises a body, the bottom and top surfaces of which are coated with first and second waterproof paint layers 7. The middle part of the body is provided with a sleeve hole 8 which is used for being sleeved into the pipeline 4, so that the connection with the pipeline 4 can be realized, and meanwhile, the waterproof performance is kept. The waterproof prefabricated member body is formed by three layers of materials from bottom to top in sequence, and the first nonwoven cloth layer 1 is used as a bottom layer, and can be used for improving the stability of the structure and protecting other layers. The rubber material layer 2 is located in the middle for providing elasticity, water resistance and waterproofing performance to ensure the waterproofing effect. The second nonwoven layer 3 serves as a top layer for protecting the inner layer and providing an aesthetic appearance. The three-layer structure is compounded through the steps of heat treatment or solidification, lamination, cooling and solidification, cutting and shaping, and the like.

Referring to fig. 2, in the present utility model, a first waterproof paint layer 6 and a second waterproof paint layer 7 are respectively coated on the bottom surface and the top surface of the waterproof prefabricated member body, and the paint layers help to prevent moisture penetration and protect the internal materials of the prefabricated member from moisture.

As some preferred examples, the root waterproof preform meets the waterproof IP67 standard, and the rubber of the rubber material layer 2 has an elongation at break of not less than 400% and a tensile strength of not less than 35N/mm, and this high ductility and strength contribute to coping with various environmental changes and provide excellent waterproof performance. These performance metrics are important metrics for evaluating the elasticity and strength of a material. Elongation at break refers to the percentage increase in length of a material from the onset of force to the final break under an applied force. For example, if the rubber material is 100 mm in length at the beginning and becomes 150 mm in length at break after being subjected to a tensile force, the elongation at break is (150-100)/100×100% =50%. Therefore, the elongation at break of more than or equal to 400 percent indicates that the rubber material can be obviously stretched under the condition of stress and has better elasticity. Tensile strength refers to the ability of a material to resist tensile forces under external forces. It is generally expressed in N/mm ² (newtons per square millimeter) or MPa (megapascals). A tensile strength of 35N/mm or more means that the rubber material is capable of withstanding a force of at least 35N per square millimeter of cross-sectional area when subjected to a tensile force.

The requirements of the above-mentioned performance parameters indicate that the elasticity and strength of the rubber material layer 2 are highly required. The achievement or exceeding of these performance indicators will ensure that the preform has good durability, deformation resistance and water resistance in the application.

As some preferred examples, the rubber material may employ any one of styrene-butadiene rubber (SBR), ethylene-propylene rubber (EPDM), chloroprene Rubber (CR), silicone rubber (VMQ), fluororubber (FKM), chlorosulfide rubber (CSM), natural Rubber (NR).

As some preferred examples, the inner rim of the rubber material layer 2 is turned up to form a flange portion 9 for fitting with the outer wall of the pipe 4 to achieve a tight seal. This design can provide better sealing, prevent moisture penetration, and ensure the waterproof effect of the root zone. The design of the flange portion 9 helps to maintain a tight fit between the pipe 4 and the preform, preventing water leakage and infiltration.

The design of the flange portion 9 improves the tightness to some extent, especially in cases where it is necessary to achieve a seal between the pipe 4 and other structures. This design prevents moisture, dust, etc. from entering around the pipe 4, thereby maintaining the integrity and waterproof properties of the pipe 4.

In the actual construction process, it is necessary to ensure that the flange portion is properly attached to the outer wall of the pipe 4 to avoid occurrence of voids or unevenness

As some preferred examples, the inner diameter of the rubber material layer 2 is smaller than the diameter of the pipe 4, and since the rubber material has flexibility and ductility, when the inner diameter of the rubber material layer 2 is slightly smaller than the diameter of the pipe 4, it is possible to ensure that the flange portion is fitted to the outer wall of the pipe 4.

As some preferred examples, any one of a polymer paint, a polyurethane paint, an epoxy paint, an acrylic paint, or a silicone rubber paint may be used including the first waterproof paint layer 6 and the second waterproof paint layer 7.

As some preferred examples, the shape of the trepanning 8 may be circular, oval or rectangular to accommodate the size and shape of different pipes 4.

As some preferred examples, the first and second nonwoven fabric layers 3 may be nonwoven fabrics of different materials and/or different densities to provide different properties and waterproof effects. For example:

(1) The waterproof performance is improved:

First nonwoven layer 1: the polypropylene non-woven fabric with high density is selected, so that the waterproof performance and permeation resistance are better.

Second nonwoven fabric layer 3: the lower density polyester nonwoven is selected to provide better softness and flexibility.

The design can realize higher waterproof performance on the pipe root waterproof prefabricated member, and is suitable for environments needing high waterproof protection, such as a groundwater pipeline 4.

(2) Durability and abrasion resistance

First nonwoven layer 1: a high density nylon nonwoven fabric is used to increase abrasion resistance and durability.

Second nonwoven fabric layer 3: a low density polyethylene nonwoven fabric is used to maintain softness and flexibility.

This design can be used in situations where it is used for a long period of time and it is necessary to withstand a certain wear, such as industrial piping 4 systems.

(3) Special chemical environment

First nonwoven layer 1: polytetrafluoroethylene (PTFE) nonwoven fabrics with high chemical stability are selected to resist attack by chemicals.

Second nonwoven fabric layer 3: polypropylene nonwoven fabrics are employed to provide adequate strength and stability.

The bottom surface and the top surface of waterproof prefab body are the non-woven fabrics respectively, can increase the adhesive force between waterproof coating layer and the waterproof prefab body.

This layer of coating will become an adhesive layer of the preform, helping to ensure adhesion between the preform and the substrate 5.

Sleeving the waterproof prefabricated member body: the waterproof prefabricated member is sleeved on the outer side of the pipeline 4 from top to bottom until the prefabricated member reaches the pipe root. In the sleeving process, the prefabricated member and the base surface are ensured to be attached flatly, and hollowness or wrinkles are avoided.

Brushing a second waterproof paint layer 7 on the top surface of the second non-woven fabric layer 3 of the waterproof prefabricated member: and a second waterproof paint layer 7 is painted on the top of the waterproof prefabricated member to achieve an integral effect with the base material 5 so as to further improve the waterproof effect.

Through the steps, the waterproof prefabricated member realizes the processes of attaching to the outer wall of the pipeline 4, bonding to the base material 5 and brushing waterproof paint. The design adopts a three-in-one flexible structure, combines different materials and waterproof paint layers, solves the problems of uneven painting of waterproof paint, short service life and the like, has better deformation resistance, and is suitable for different environmental occasions. Such a design is expected to provide a more durable and reliable waterproof effect in indoor waterproof construction.
