Description

Technical Field

[0001] The utility model relates to the technical field of spray-bonded cotton, in particular to heat-insulating thick spray-bonded cotton. Background Art

[0002] Spray-bonded cotton is an item made of several layers of fiber web stacked together by a web laying machine after loosening and carding. Adhesive is sprayed on the fiber web during the laying process. When the spray-bonded cotton leaves the assembly line, it is often wound into a roll by a winder or cut into several pieces by a slitting machine for sale.

[0003] Spray-bonded cotton has good thermal insulation effect. Therefore, existing thermal insulation spray-bonded cotton is often used to cover pipes. In order to increase the thermal insulation performance, a common method is to extrude the spray-bonded cotton through a roller machine to make the spray-bonded cotton thicker.

[0004] However, the hardness of the spray-bonded cotton increases after being squeezed by the pressure roller, making it difficult to cover the pipe smoothly. A gap is easily formed between the inner surface of the cotton and the pipe surface when covering the pipe, resulting in a reduction in the thermal insulation effect of the spray-bonded cotton on the pipe.

[0005] In view of the above problems, a technical solution of thermal insulation spray-bonded cotton is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problems in the prior art and to propose a heat-insulating thick spray-bonded cotton.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: thermal insulation thick spray-bonded cotton, including a laid base layer and a surface layer, a number of spaced barrier blocks are embedded between the base layer and the surface layer, the two sides of the barrier blocks are respectively bonded to the base layer and the surface layer, the surface layer and the base layer are compacted toward the end faces of the several barrier blocks, and the several barrier blocks can undergo elastic deformation to bring the base layer and the surface layer closer, and a number of thermal insulation cavities are formed between the base layer and the surface layer.

[0008] The utility model is further configured as follows: the peripheral side of the barrier block is formed into a wavy concave-convex surface.

[0009] The utility model is further configured as follows: the barrier blocks are formed into a rectangular structure, and the spacing between adjacent barrier blocks is greater than the width of the barrier blocks in the same direction.

[0010] The utility model is further configured as follows: an opening with a circular cross section is provided in the barrier block.

[0011] The utility model is further configured as follows: the barrier block is made of high-temperature resistant rubber material.

[0012] The utility model is further configured such that: the base layer and the surface layer are intertwined at positions between adjacent barrier blocks.

[0013] In summary, the utility model has the following beneficial effects: when the spray-bonded cotton is used to cover the pipe, the deformation of the barrier block is utilized to drive the surface layer and the base layer to be dislocated, so that the deformation occurring on the base layer is transformed into making the surface layer close to the base layer, and at the same time, the compacted positions on the surface layer and the base layer are staggered, thereby improving the warmth retention of the spray-bonded cotton.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments.

[0017] Insulation thick spray-bonded cotton, such as Figure 1 As shown, natural cotton fibers are laid into a fiber web by a carding machine, an adhesive is sprayed on the surface, and finally dried to form a base layer 1 and a surface layer 2. Soft glue is sprayed on the adjacent end surfaces of the base layer 1 and the surface layer 2, and then a number of spaced-apart barrier blocks 3 are placed between the base layer 1 and the surface layer 2. The two sides of the barrier blocks 3 are respectively bonded to the base layer 1 and the surface layer 2 by soft glue. At this time, a number of insulation cavities 4 are formed between the base layer 1 and the surface layer 2.

[0018] Among them, the barrier block 3 is made of high-temperature resistant rubber material. Taking the covering of hot water pipes as an example, the barrier block 3 can be made of butyl rubber. After the soft glue dries, the surface layer 2 and the base layer 1 are compacted toward the end faces of several barrier blocks 3 through a press, so that the two sides of the barrier block 3 are respectively embedded in the surface layer 2 and the inner layer. At the same time, the fiber density of the surface layer 2 and the inner layer on both sides of the barrier block 3 is larger than that at other positions.

[0019] Beneficial effect: When the spray-bonded cotton is used to cover the pipe, the position where the spray-bonded cotton bends due to fitting the pipe is limited to several compacted positions of the base layer 1, that is, the compacted positions on the base layer 1 do not deform to a large extent, but the uncompacted positions on the base layer 1 are bent. In order to ensure that the uncompacted positions do not form gaps with the pipe due to bending, several barrier blocks 3 can undergo elastic deformation to bring the base layer 1 closer to the surface layer 2. That is, the deformation of the barrier blocks 3 is used to drive the surface layer 2 and the base layer 1 to be dislocated, so that the deformation on the base layer 1 is transformed into making the surface layer 2 close to the base layer 1, and at the same time, the compacted positions on the surface layer 2 and the base layer 1 are staggered, thereby improving the warmth retention of the spray-bonded cotton.

[0020] like Figure 1 As shown, in order to make the barrier block 3 more stably bonded to the base layer 1 and the surface layer 2, specifically, the barrier block 3 is formed into a rectangular structure, the spacing between adjacent barrier blocks 3 is greater than the width of the barrier block 3 in the same direction, and an opening 32 with a circular cross-section is provided in the barrier block 3. The peripheral side of the barrier block 3 is formed into a wavy concave and convex surface 31. At the same time, the end surface of the barrier block 3 that is not bonded to the surface layer 2 and the base layer 1 after deformation is also left with a gap, thereby effectively maintaining the warmth-keeping effect of the insulation cavity 4. The circular opening 32 prevents cracks from being generated inside the barrier block 3 due to deformation.

[0021] like Figure 1 As shown, in order to make the connection between the base layer 1 and the surface layer 2 more secure, the base layer 1 and the surface layer 2 are intertwined at the position between adjacent barrier blocks 3.
