Description

Technical Field

[0001] The invention relates to the technical field of bamboo springs, and in particular to the preparation and application of a composite bamboo-based spring material and a mattress. Background Art

[0002] In the current market, spring mattresses mostly use metal springs as the supporting structure. Such mattresses are usually heavy and inconvenient to carry. Although metal spring mattresses are popular due to their excellent support and good air permeability, their production process is often accompanied by high energy consumption and high emissions, which easily pollutes the environment. The traditional bamboo fiber mattress manufacturing requires flattening, dissociation, gluing, and molding of bamboo materials, which is complex and energy-intensive. This bamboo fiber mattress manufacturing method destroys the original high elasticity and high toughness structure of bamboo materials, which is not conducive to the reshaping of the elastic structure of the mattress filling material. At the same time, bamboo fiber mattresses are hard and have poor air permeability, which affects the comfort of use and cannot achieve precise regulation of the softness and hardness of the mattress to meet the needs of different groups of people. Therefore, studying substitutes for metal springs and developing green, low-carbon and environmentally friendly biomass mattress filling materials with excellent performance will be an inevitable trend for the future development of the mattress industry.

[0003] Bamboo has a short growth cycle, strong regeneration ability, fast reproduction speed, is green and pollution-free, has good degradability, biocompatibility, high strength and excellent toughness, and its processing technology is simple, so it is widely used in many fields such as construction, home furnishing and textiles. In addition, bamboo exhibits excellent flexibility. The bamboo spring prepared by winding molding has a specific stiffness comparable to that of metal springs for mattresses, but it has shortcomings such as low absolute stiffness level and poor dimensional stability. Therefore, it is necessary to increase the stiffness of bamboo springs to broaden their stiffness range and improve their dimensional stability to meet the support performance of mattresses and their quantitative regulation, and realize the lightweight design of mattresses.

[0004] Inventive content

[0005] The purpose of the present invention is to solve the above-mentioned shortcomings and provide a preparation and application of a composite bamboo-based spring material and a mattress.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A method for preparing a composite bamboo-based spring material comprises the following steps:

[0008] S1. Drawing bamboo materials to obtain bamboo filaments, using the bamboo filaments as base materials for water bath softening and shaping treatment to obtain bamboo-based springs:

[0009] S2. Modify the bamboo-based spring after being treated in S1:

[0010] S2.1, mixing and stirring the resin, curing agent and filler to obtain a modified solution;

[0011] S2.2, modifying the bamboo-based spring by spraying the modified solution on the surface of the bamboo-based spring or immersing the bamboo-based spring in the modified solution and turning it over;

[0012] S2.3, placing the modified bamboo-based spring horizontally on a silicone bracket, and after the modified solution on the surface of the bamboo-based spring is solidified, a modified bamboo-based spring is obtained;

[0013] S3. Polishing the modified bamboo-based spring treated by S2 to obtain a composite bamboo-based spring.

[0014] Furthermore, the S1 includes:

[0017] S1.3, wind the bamboo wire treated in S1.2 into the coiled spring rod core and continue water bathing for 1 to 2 hours;

[0018] S1.4. After the water bath is finished, the bamboo wire is fixed on the coil spring rod core to shape and dry to obtain the bamboo-based spring.

[0019] Furthermore, the resin in S2 is epoxy resin, polyurethane resin, acrylic resin, bio-based resin, the curing agent includes 593 curing agent or CPU061, the filler is a filler, a stabilizer or a nanomaterial, and the filler specifically includes nano-silicon dioxide, nano-titanium dioxide, and graphene oxide, wherein the mass ratio of resin, curing agent and filler is 20-60:10:1-4.

[0020] Furthermore, the wire diameter range of the composite bamboo-based spring is 2-3 mm, 3-4 mm, 4-5 mm, 5-6 mm; the diameter range is 4-5 cm, 5-6 cm, 6-7 cm, 7-8 cm; the free height is 6-28 cm; the density range is 1.0-2.0 g / cm 3 , the stiffness range is 0.05~0.5N / mm.

[0021] A composite bamboo-based spring mattress comprises an upper mattress layer, a mattress support layer and a lower mattress surround;

[0080] The comfort layer 32 of the mattress is made of one or a combination of latex, foam sponge, wool, horse hair, camel hair, down, and loofah silk;

[0081] Among them, wool, horse hair, and camel hair are processed sheets;

[0082] The down or loofah silk floss is a sheet-like liner, and the liner skin is a non-woven fabric or cloth, and the down or loofah silk floss is evenly distributed through quilting;

[0083] Loofah silk floss is formed by breaking the loofah into silky pieces.

[0084] The support layer 33 of the mattress is composed of a support layer perimeter 334, a base layer 333 and a plurality of composite bamboo-based spring units 331;

[0085] Each composite bamboo-based spring unit 331 is an independent bagged structure, including a composite bamboo-based spring body 1 and a non-woven bag 2 covering the composite bamboo-based spring;

[0086] Wherein, the composite bamboo-based spring is prepared by adopting the above preparation method.

[0091] The composite bamboo-based spring units 331 are arranged in the form of multiple composite bamboo-based spring module packages 332; wherein the composite bamboo-based spring module package 332 specifically includes a non-woven fabric package and multiple composite bamboo-based spring units 331 arranged in a matrix arrangement in the non-woven fabric package; on the composite bamboo-based spring module package 332, adjacent composite bamboo-based spring units 331 are separated by a dividing line.

[0092] The composite bamboo-based spring module package 332 may be rectangular, square or triangular; the dividing line on the composite bamboo-based spring module package 332 may be a quilting dividing line, a zipper tape dividing line or a heat-pressed bonding dividing line.

[0093] Furthermore, in this embodiment, the support layer edge 334 is made of non-woven fabric; each composite bamboo-based spring module package 332 can be connected to each other through the non-woven fabric and together form a spring bed net. The lower surface of the spring bed net is provided with a layer of 400-800g / m 2 Cotton felt or other felt-like base layer with a certain elasticity 333.

The composite bamboo-based spring module package 332 can be a variety of shapes such as rectangle, square, triangle, etc., and a module of a specific shape is formed by arranging and combining a number of composite bamboo-based spring units, and then wrapped with non-woven fabric and connected with other spring module packages to achieve partial replaceability of the composite bamboo-based spring layer.

[0099] (2) In response to the sleep support needs of people of different body shapes, this study selected composite bamboo-based springs of different specifications and density levels. At the same time, considering the different support needs of different parts of the human body such as the head, waist, buttocks, legs and feet during sleep, composite bamboo-based spring layer areas with different support performance are designed. These areas use composite bamboo-based springs of different specifications and density levels to meet the support needs of various parts of the body. When different areas are composed of composite bamboo-based spring modules in rectangular, triangular and other shapes, these modules are wrapped with non-woven fabrics and connected to other spring modules. This design not only allows partial replacement of the composite bamboo-based spring layer, but also realizes the functional zoning of the mattress, as well as the customized production and design of the mattress.
