Technical Field

[0001] This invention patent belongs to the field of building materials technology, and specifically relates to a woven reinforced cotton board. Background Technology

[0002] Woven reinforced cotton board is specifically designed and manufactured for Class A fire-retardant exterior wall insulation thin-plaster systems in buildings. It is suitable for exterior wall insulation or energy saving in new or existing buildings with dense structures such as concrete or brick walls. Traditional cotton board materials still have shortcomings in terms of low compressive and tensile strength when used in building exterior wall insulation applications. Serious defects such as uneven surface and deformation and cracking during construction pose serious risks to personal and property safety within the building's surrounding environment. Summary of the Invention

[0003] To address the above problems, this invention provides a woven reinforced cotton board for thermal insulation, which solves the problems of low compressive and tensile strength, wall shrinkage and deformation, poor overall integrity of the cotton board, and easy loosening and falling off after weathering, oxidation and water seepage.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a woven reinforced cotton board, comprising a cotton board body and reinforcing layers respectively disposed on the surface of the cotton board body. The reinforcing layers are formed by the intersection of the warp and weft threads of the reinforcing layers to form a small grid. A sewing thread is disposed above the reinforcing layers. The sewing thread is characterized in that: the sewing thread is used to sew and fix the cotton body to the reinforcing layer on the surface of the cotton body through the upper and lower surfaces of the cotton body by means of a loop-locking reciprocating penetration of the sewing thread. The sewing thread includes an upper reciprocating penetrating thread that passes through the sewing needle hole from the upper surface and a lower reciprocating penetrating thread that passes through the sewing needle hole to the lower surface, as well as a loop-locking thread connected to the end of the lower reciprocating penetrating thread. The loop-locking thread on the lower reciprocating penetrating thread that passes through one sewing needle hole forms a loop-locking connection with the lower reciprocating penetrating thread that passes through the adjacent sewing needle hole.

[0005] The sewn mesh panel has an outer surface finishing layer on both sides. An adhesive layer is provided between the outer surface finishing layer and the rock wool board. The quilted mesh layer increases the overall stability of the rock wool board. The adhesive layer between the lightweight outer surface finishing layer on both sides of the rock wool board and the mesh-reinforced rock wool board improves the stability of the mesh-reinforced rock wool composite board body. It has high compressive strength. The adhesive layer can prevent the mesh-reinforced rock wool composite board body from loosening and falling off, and increases waterproofness and surface flatness.

[0006] The aforementioned woven reinforced cotton board is characterized in that the sewing thread can be directly embedded into the rock wool board body through the sewing thread penetration line on the upper and lower surface layers of the cotton body, and the sewing thread is fixed to the surface layer of the board body by reciprocating loop sewing.

[0007] The aforementioned woven reinforced cotton board is characterized in that the reinforcing layer on the surface of the cotton board is the upper and lower surfaces or one side of the cotton body. The reinforcing layer is fixed to the surface layer of the board body by interlocking and sewing with the rock wool board body through the thread penetration thread.

[0008] The aforementioned woven reinforced cotton board is characterized in that the stitching is radial stitching or warp and weft stitching followed by overlapping of the stitches to form a cross-shaped large mesh.

[0009] The aforementioned woven reinforced cotton board is characterized in that the sewing thread is alkali-resistant and fire-retardant fiber thread or nylon thread.

[0010] The aforementioned woven reinforced rock wool board is characterized in that the sewing thread is an alkali-resistant fire-retardant fiber thread or nylon thread that is alternately sewn in a row ratio.

[0011] The aforementioned woven reinforced cotton board is characterized in that the weft yarn of the reinforcing mesh layer is a double-wound fine yarn, and the warp yarn is a flat yarn that crosses the double-wound fine yarn.

[0012] The aforementioned woven reinforced cotton board is characterized in that the sewing thread material is presented as an upper and lower sewing thread connecting post in each sewing hole of the cotton board body; the sewing thread material includes a thread material that passes through the cotton body from the upper surface layer, fixing and connecting the upper and lower surface layers of the panel body.

[0013] The aforementioned woven reinforced cotton board is characterized in that the sewing thread forms an intermittent embedded reciprocating sewing pattern on the surface of the cotton board body, connecting and fixing the upper and lower surface layers.

[0014] The aforementioned woven reinforced cotton board is characterized in that the sewing thread forms a reciprocating interlocking sewing structure on the cotton board body.

[0015] The aforementioned woven reinforced cotton board is characterized in that the reinforcing layer is formed by the intersection of warp and weft threads to create a small grid pattern.

[0016] The aforementioned mesh-reinforced cotton board, after being sewn horizontally and vertically, has a cross-grid pattern after the sewing threads overlap on the surface of the cotton board and the reinforcing layer. The upper reciprocating thread, lower reciprocating thread, and loop thread of the same quilting are a complete thread connected end to end.

[0017] The stitching material is presented as multiple upper and lower stitching connecting posts in each stitching hole of the cotton board.

[0018] The aforementioned woven reinforced cotton board is characterized in that the cotton board body is coated with an outer surface interface agent by applying an outer surface interface agent to the stitch lines between the sewn surface of the cotton board body and the surface of the cotton body. The aforementioned woven reinforced cotton board is characterized in that the cotton board body is sewn through the upper and lower surfaces of the cotton body repeatedly, and a lightweight outer surface finishing layer is provided on the upper and lower surfaces of the cotton body after sewing is completed, and an adhesive layer is provided between the lightweight outer surface finishing layer and the cotton board.

[0019] The aforementioned woven reinforced cotton board is characterized in that the lightweight outer surface composite layer has a flame retardant rating of Class A. The aforementioned woven reinforced cotton board uses water-repellent cotton and has a thickness of 2CM-50CM, which can be customized according to the regional temperature.

[0020] The beneficial effects of this invention are as follows: Based on traditional cotton boards, this invention uses reciprocating thread, reciprocating thread, and interlocking loops to form quilted threads that pass through the upper and lower surfaces and the needle holes. All the stitches are intermittently embedded reciprocating stitches outside the reinforcing mesh layer on the upper and lower surfaces. All the stitches in the needle holes form a vertical multi-point column fixing structure within the rock wool board. The distance between the needle holes can be set according to the usage requirements, usually between 10mm and 5000mm. This allows the upper and lower mesh layers to firmly lock the cotton body through the multi-point fixing structure after the interlocking loops of the stitches. This solves the problems of poor overall integrity of cotton boards, low compressive and tensile strength, and completely eliminates the hidden dangers of cotton boards easily loosening and falling off after weathering, oxidation, and water seepage.

[0021] After the woven reinforced cotton board of the present invention is sewn with sewing thread, the tensile strength of the cotton body perpendicular to the surface is increased from the original 10-15KPa to 120KPa, which is 12 times higher than the original tensile strength. This effectively enhances the overall performance and wind load resistance of the cotton body without increasing the overall weight.

[0022] The sewn mesh-reinforced cotton board has an outer surface finishing layer on both sides, and an adhesive layer, which is an adhesive or adhesive paste, is provided between the outer surface finishing layer and the cotton board. The quilted mesh layer increases the overall stability of the cotton board, and the adhesive layer between the lightweight outer surface finishing layer on both sides of the cotton board and the mesh-reinforced cotton board improves the stability of the mesh-reinforced cotton board body, resulting in high compressive strength. The adhesive layer prevents the mesh-reinforced rock wool board body from loosening and falling off, increases the waterproofness of the mesh-reinforced cotton board body, and ensures good surface flatness of the mesh-reinforced cotton board body.

[0023] The outer surface finishing layer provided on both sides of the woven reinforced cotton board of the present invention can effectively increase the compressive strength of ordinary cotton board from 20KPa to 59KPa, and also prevent water from seeping into the surface of the woven reinforced cotton board, thus effectively increasing its waterproof performance.

[0024] The performance indicators of the sewn-woven material are superior to the national standard values ​​for traditional cotton materials. Reference standards include: "Rock Wool Products for External Wall Insulation," "Classification of Combustion Performance of Building Materials and Products," and "Materials for Rock Wool Thin-Plaster External Wall Insulation Systems."

Detailed Implementation

[0026] This invention discloses a woven reinforced cotton board, with reference to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a cotton board body 1 and reinforcing layers 2 respectively attached to the upper and lower surfaces of the cotton board body 1. The reinforcing layers are applied to the surface of the cotton board body, and the cotton board body 1 is made of water-repellent cotton.

[0027] The reinforcing layer 2 consists of a small grid formed by the cross-section of warp threads 8 and weft threads 9. The sewing thread 3 is woven using a combination of horizontal and vertical cross-loop stitching, forming a large cross-shaped grid on the surface. The sewing thread 3 is made of alkali-resistant and fire-retardant fiber or nylon thread. Within the same needle hole 4, there are reciprocating stitches forming vertical connecting posts. Adjacent needle holes are connected by loops 7, and the same quilted thread is a complete thread with its ends connected.

[0028] The cotton board body 1 of the present invention is provided with a plurality of sewing needle holes 4, which are evenly distributed in an array or randomly distributed. The sewing thread 3 is an alkali-resistant and fire-retardant fiber thread or nylon thread, including an upper reciprocating penetrating thread 5 that is embedded in the sewing needle hole 4 on the upper surface of the cotton board body 1 and a lower reciprocating penetrating thread 6 that passes through the sewing needle hole 4 on the lower surface of the cotton board body 1. A cross loop 7 is connected to the end of the lower reciprocating penetrating thread 6. The cross loop 7 on the lower reciprocating penetrating thread 6 that passes through one sewing needle hole 4 is connected to the upper reciprocating penetrating thread 5 that passes through the adjacent sewing needle hole 4. The upper reciprocating penetrating thread 5, the lower reciprocating penetrating thread 6 and the cross loop 7 that pass through all the sewing needle holes 4 on the same cross section of the cotton board body 1 are a single thread connected end to end.

[0029] Each needle hole 4 contains two reciprocating stitches 3. All stitches 3 are intermittently embedded reciprocating stitches outside the reinforcing layer 2 on the upper and lower surfaces of the cotton board 1, such as... Figure 4 , Figure 5 As shown, all the sewing threads 3 inside the sewing needle holes 4 form a vertical multi-point column fixed connection structure inside the cotton board body 1.

[0030] The reinforcing layer weft 9 is a double-wound fine yarn, and the warp 8 is a flat yarn, made of fiberglass or metal. After sewing, an A-grade flame-retardant lightweight outer surface layer 11 is laminated through an adhesive layer 10 to improve the overall integrity, waterproofness, and smoothness.

[0031] The dimensions of the reinforcing layer 2 and the sewing thread 3 of the present invention can be customized, and conventional sizes can be used. The sewing thread 3 increases the stability of the reinforcing layer 2 and the deep adhesion between the reinforcing layer 2 and various media, without increasing the overall weight.

[0032] After the weaving is completed, the surface of the woven reinforced cotton board is laminated with an adhesive layer 10 and an outer decorative layer 11 to improve compressive strength. This ensures that the woven reinforced cotton board body does not loosen or fall off, increases the waterproofness and overall performance of the woven reinforced cotton board body, and results in good surface flatness of the woven reinforced cotton board body. The cotton board body 1 is preferably 2-25 cm thick, and the density and type of cotton board are not limited. This significantly increases the tensile strength of the cotton board body 1 under external force, thereby greatly increasing the safety of people and property within the building's environmental range.

[0033] All materials used in this invention are fire-resistant, waterproof, alkali-resistant, high-strength, static-free, and possess high levels of tensile, pull-out, and impact resistance. The surface of the cotton board after sewing and lamination is smooth, with strong adhesion, and it can be bonded to various adhesives. A thin layer of adhesive achieves excellent bonding, thus saving construction costs and reducing the overall weight of the thermal insulation layer. It can be widely used in various high-temperature insulation systems. The best-selling product for insulation, heat insulation, corrosion prevention and moisture protection in low-rise buildings and aviation fields.

[0034] The products of this invention are manufactured and processed using professional industrial sewing machines, which require less manpower, have low additional costs, and are fast in processing. The processing equipment is small, lightweight and easy to move. The sewing and batch processing can be completed in front of the packaging equipment in the traditional cotton material production process. The production and processing equipment can also be placed in a separate site for processing, such as a small or medium-sized building material processing plant, a construction and installation site with suitable conditions, or on-site processing and manufacturing according to the on-site usage requirements.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some of the application examples. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
