AI Technical Summary
Traditional thermal insulation quilts have pinholes in their manufacturing process, which affects their waterproof performance. Furthermore, the quilt core is prone to shifting during repeated rolling, leading to a decrease in localized insulation performance. In addition, the cotton is prone to becoming damp and collapsing after long-term use, increasing production costs.
Using a pinhole-free process, the quilt core is wrapped with a rainproof cloth and a composite layer. Pleats and matrix stitching points are set on the outer wall of the cotton quilt cover. Combined with nano-level aerogel powder and waterproof adhesive, a composite layer is formed to enhance waterproofness and moisture resistance and limit the movement of the quilt core.
It achieves pinhole-free waterproof performance, prevents cotton from getting damp and collapsing, improves thermal insulation performance, reduces production costs, and ensures uniform distribution of the quilt core and long-term thermal insulation effect.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of nanometer coating heat preservation cotton quilt based on pinhole free process, specifically nanometer coating heat preservation cotton quilt based on pinhole free process. BACKGROUND
[0002] Traditional heat preservation cotton quilt often adopts sewing process in the manufacturing process, causes the existence pinhole on the surface of cotton quilt, has influenced waterproof performance. Meanwhile, the core is easy to move in the repeated rolling process, causes the local heat preservation performance to drop. In addition, the cotton is easy to be damped and collapse after long -term use of traditional cotton quilt, needs excessive filling to maintain heat preservation performance, increases production cost. SUMMARY
[0003] To solve above -mentioned problem, namely solves the problem of above -mentioned background art, the utility model provides a kind of nanometer coating heat preservation cotton quilt based on pinhole free process, including quilt core and raincoat, the outer wrapping of quilt core has raincoat, the raincoat adopts bagged type with one side opening, the opening of raincoat is set into the structure of fitting, and the overlapping gap is filled by composite layer for bonding;
[0004] The composite layer adopts waterproof glue mixed with aerogel powder.
[0005] The utility model further provides that: the outer wall of the quilt core is wrapped with a quilt cover, and the composite layer is also filled between the quilt cover and the raincoat.
[0006] The utility model further provides that: the outer wall of the quilt cover is provided with wrinkles for increasing the bonding strength.
[0007] The utility model further provides that: the quilt cover is provided with a plurality of stitching points for stitching the upper and lower quilt covers together through the quilt core.
[0008] The utility model has the beneficial technical effects that: through the pinhole free process and the setting of the composite layer, the moisture-proof and heat preservation performance of the quilt is ensured, and the cotton will not be damped and collapse after long-term use. Through the design of the wrinkles and the setting of the matrix stitching points, the movement of the quilt core is limited, the uniform distribution of the cotton is ensured, and the overall heat preservation performance is improved. The application reduces the production cost while ensuring the heat preservation performance, and does not need to use excessive filling. BRIEF DESCRIPTION OF DRAWINGS

[0013] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.
[0014] The utility model discloses a kind of nano coating thermal insulation cotton quilt based on pinhole-free process, the closing of waterproof cloth 1 of outermost layer is adhered by composite layer 2, so that there is no any pinhole on the outer surface of thermal insulation quilt, ensure the waterproof performance of waterproof cloth, while the cotton quilt cover 3 of wrapping quilt core 4 is also filled with composite layer 2 between waterproof cloth 1, composite layer 2 uses including but not limited to nanometer aerogel powder and waterproof glue, aerogel and waterproof glue are fully wrapped around quilt core, increase the overall moisture-proof thermal insulation, avoid that quilt core is eroded by rainwater moisture and collapse, ensure thermal insulation performance.
[0015] Wrinkle protrusion is sewn or printed on the outer wall of cotton quilt cover 3, increase the contact area with composite layer 2, ensure the composite strength, avoid that quilt core is moved in waterproof cloth when cotton being rolled and unrolled by big shed roll quilt device, cause composite layer to crack.
[0016] By sewing the upper and lower two layers of cotton quilt cover 3 at a point, and the point can pass through the inside of quilt core, the sewing point 5 is set into matrix, avoid that cotton of quilt core 4 is moved in repeated roll quilt process, affect local thermal insulation performance.
[0017] By limiting the movement of cotton to ensure uniform distribution of cotton, by pinhole-free process and the setting of composite layer, the moisture-proof and thermal insulation performance of cotton quilt is ensured, cotton will not be damp and collapse after long-term use, without using excessive filling form, while ensuring thermal insulation performance, reduce production cost.
