Specific embodiment
With reference to the accompanying drawing and the embodiment of the present invention to the production technology of bamboo charcoal nano sping mattress of the invention make into
One step detailed description.
As shown in Figure 1, the production technology of bamboo charcoal nano sping mattress, includes the following steps:
Step 1: spring coiling machine is rolled into support spring 1.The material of support spring 1 is selected as plating wrought steel line.The original of support spring 1
Material by 1500 DEG C ~ 2000 DEG C of heating (preferred, heating temperature is 1900 DEG C), and will support bullet before wind spring machining
Spring 1 was placed into normal-temperature water within 20 seconds time, and water-bath cools to 800 DEG C ~ 850 DEG C, and (preferred, water-bath cools to 830
DEG C).The toughness that spring is improved by above-mentioned technique, avoids spring in the long-term use, and spring occurs expendable
Deformation.The service life of spring is increased by above-mentioned technique, indirectly increases the service life of mattress, and then guarantee mattress
Quality.
It include bamboo carbon powder, nano-titanium dioxide and the nano-titanium dioxide of 500 mesh sizes in the supporting layer of bamboo charcoal nano
Antibacterial agent.Bamboo carbon powder, nano-titanium dioxide and nano titanium dioxide anti-bacterial agent weight accounting are respectively as follows: bamboo carbon powder 95%, receive
Rice titanium dioxide 2%, nano titanium dioxide anti-bacterial agent 1%.Bamboo charcoal nano surface area is big, and deodorization can be carried out to ingress of air, is removed
Wet and sterilization effect can keep higher sanitary conditions to ensure that mattress in the long-term use, guarantee human body
Health.And nano-titanium dioxide illumination effect under, can occur catalysis reaction, generate the extremely strong free radical of oxidation susceptibility and
Active oxygen can decompose pollutant remaining in mattress, further function as antibacterial and bactericidal effect.Same nanometer titanium dioxide
Titanium antibacterial agent increases the oxidation susceptibility of nano-titanium dioxide, further improves the antibacterial and bactericidal property of mattress, guarantees to make
With the health of personnel.
Step 2: support spring 1 is by wearing spring wound into spring core.Spring core dresses up bag by nonwoven fabric or cotton
Shape.Further such that it is independent between support spring 1, the interference free performance of mattress is improved, the comfort level of user of service is improved.
Step 3: encircling and hunting down side steel by steel wire.Side steel diameter is that 20mm ~ 25mm(is preferably, and side steel diameter is 23mm).Side
Between steel by laser welding or be bolted or riveting method connection.The intensity for guaranteeing mattress by side steel, avoids bed
The long-term sitting user of service in edge is padded, mattress edges is caused to deform, so that the mattress deformation made is unable to satisfy use, damages bed
Pad.
Step 4: inner cushion layer makes；The supporting layer that connection has bamboo charcoal nano is sutured by way of quilting, forms interior pad
Layer.Inner cushion layer is divided into the cushion course and hardcore for being respectively provided at mattress two sides.It is hardcore 31, nano bamboo that hardcore, which selects palm,
The modified nano-emulsion glue-line of the hard middle layer 32 of layer of charcoal, bamboo charcoal nano is hard upper layer 33.Cushion course select spongy layer be soft bottom 41,
The soft middle layer 42 of nano bamboo layer of charcoal, bamboo fibre layer are soft upper layer 43.In hardcore, palm hardcore 31 with a thickness of 2cm ~ 4cm, receive
The hard middle layer 32 of rice bamboo-carbon layer with a thickness of the modified hard upper layer 33 of nano-emulsion glue-line of 0.3cm ~ 0.6cm, bamboo charcoal nano with a thickness of
0.5cm~2cm；In cushion course, the soft bottom 41 of spongy layer with a thickness of 3cm ~ 5cm, nano bamboo layer of charcoal soft middle layer 42 with a thickness of
The soft upper layer of 0.3cm ~ 0.6cm, bamboo fibre layer 43 is with a thickness of 0.5cm ~ 2cm.Bamboo fibre layer includes: bamboo fibre 70%, polyester fiber
22%, polyester staple fiber 3%.Preferably, in hardcore, palm hardcore 31 is thick with a thickness of the hard middle layer 32 of 4cm, nano bamboo layer of charcoal
The hard upper layer of the nano-emulsion glue-line that degree is 0.45cm, bamboo charcoal nano is modified 33 is with a thickness of 0.8cm；In cushion course, the soft bottom of spongy layer
41 with a thickness of 4.5cm, nano bamboo layer of charcoal soft middle layer 42 with a thickness of the soft upper layer of 0.45cm, bamboo fibre layer 43 with a thickness of 1.5cm.It is logical
It crosses and difference is designed to mattress two sides hardness, allow user of service according to the happiness of physical condition and different users of service
It is good, different hardness is selected, the comfort level of user of service is improved.
Bamboo fibre layer includes: bamboo fibre 70%, polyester fiber 22%, polyester staple fiber 3%.By bamboo fibre, polyester staple fiber with
After polyester fiber mixes in proportion, using after impurities removal machine impurities removing and successively drawn, intertexture lapping at solid netted,
The cooling and shaping after high temperature is dried again, is finally cut to finished product.Using polyester staple fiber can pre- anti-mite, borrowed in baking process
Help polyester fiber low melting point melt after bamboo fibre is bonded together well with polyester staple fiber, make stable product quality,
It is anti-mite hypo-allergenic.Do not add any auxiliary agent and adhesive in process of production, it is environmentally protective without any pollution.The bamboo matter of production
Fiber mattress core material has three-dimensional space net structure, has using the mattress of bamboo fibre mattress core material production non-stimulated, anti-
The hypo-allergenic safety feature of mite, can in use can quick drain sleep when the moisture that distributes of human body, and air-permeable dampproof,
Summer uses comfortable dry and comfortable.
Step 5: cotton layer 2 is wrapped in outside inner cushion layer.By cotton layer 2 and human contact, guarantee human body and mattress
The comfort of contact surface also plays first of protective effect to mattress, avoids pollution object and penetrates into inside mattress.
The production technology of the bamboo charcoal nano sping mattress, combines sping mattress strong interference immunity, and bamboo charcoal nano is material bed
Pad improves mattress comfort level with having better effects to human health.And the technological operation is simple, to production equipment requirement
It tells somebody what one's real intentions are, reduces manufacturing cost.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
