Description
Technical field
The utility model relates to technical field of living goods more particularly to a kind of water lock cold pads.
Background technique
Currently, people pass the summer in a leisurely way, the cold pad used is usually to be made using bamboo, grass etc. as raw material, wherein bamboo mat and straw mat
Thermal coefficient (λ × 103) it is 0.3.When people uses these bamboo mats or straw mat, since human body and bamboo mat or straw mat directly connect
Touching, the body heat that human body distributes cannot all shed, so that sweat is often sticked on the dishes served at a feast, bacterium easy to breed allows people to feel not
Comfortably.Later someone's utility model water bed, heat dissipation effect are preferable.But the thermal coefficient λ of water is 1.4, with common brick (thermal coefficient
λ is 1.5) and cement floor (thermal coefficient λ is 2) is close, can excessively absorb the intracorporal heat of people.Therefore, if for a long time
If use, it may appear that the phenomenon that muscle arthrosis is ached, whole body is weak and feeble.
CN103342994A discloses the cold pad that a kind of cold-storage heat-conductive composite material is glue core.By using cool property plant reed
Stabilizer, active thionating agent, poly- cryogen and curing agent is added as raw material in luxuriant growth liquid and/or cactus liquid, obtains after mixing
The cold-storage heat-conductive composite material that thermal coefficient is 0.6~1.0.By the cold-storage heat-conductive composite material forming and hardening of the utility model
After obtained the thermally conductive cold pad of cold-storage, it is relatively low so that the body that human body distributes preferably to solve traditional cold pad thermal coefficient at present
The problem of heat cannot export completely, while it is permanent also to solve the problems, such as that human heat loses.
CN104840037A discloses a kind of water conservation cold pad, including the film adhered thin-film body of two panels, has two in thin-film body
A above independent closing blister cavities is beading between blister cavities, fills saturated brine solution in blister cavities.The resistance to compression energy of this cold pad
Power depends on the beading between blister cavities, and compression rear surface out-of-flatness, comfort level is not fully up to expectations, and is pierced through by sharp object
It is also easy to leak afterwards, product service life is short, and the requirement to outer bag material is also high.
Gel cold pad is that summer sleeping mat product of a new generation, and original summer sleeping bamboo mat on the market, straw plaited summer sleeping mat, skin summer sleeping mat etc. are refrigerant
Product allows it not only to accomplish summer sleeping mats more all kinds of than tradition more at refrigerant aspect compared to more high-tech material and technology is applied
Refrigerant, the duration of cooling off oneself is longer, and because of soft and elastic gel and pure cotton cloth surface, makes one available more comfortable
Cooling feeling, become preferable summer sleeping mat product on the market.
CN102674228A discloses a kind of gel cold pad that room temperature causes, and is crosslinked by the formation of interior material formula polymerized at normal temperature
Sodium Polyacrylate is the gel cold pad of content, is had no irritating odor, high-efficient, but still falls within flow-like content, people
Be sitting in this kind of cold pad and a problem generally occur: people is often part, non-uniform, flow-like content to the pressure of cold pad
Object is extruded to the small place that is pressurized from the big place that is pressurized, and the contact surface for actually causing body and seat cushion has greatly
Not sufficient heat eliminating medium, cannot form book is effectively to cool down, and be also easy to that leakage occurs after being pierced through by sharp object.
There are also the cold pads for using conventional polyurethanes sponge being water suction filler in existing cold pad, although cheap and easy to get, sponge water conservation
Performance is very poor, little to the raising of resistance to compression and cooling effect.
To sum up, it would be highly desirable to develop that a kind of crushing resistance is good, comfort level is high, the cold pad of not easy-to-leak liquid.
Utility model content
In view of problems of the prior art, one of the purpose of this utility model is to provide a kind of crushing resistance good, easypro
Moderately high, not easy-to-leak liquid water lock cold pad.
For this purpose, the utility model adopts the following technical solution:
In a first aspect, the utility model provides a kind of water lock cold pad, spongy layer including water of satisfying and it is coated on outside spongy layer
Outer bag formation closed chamber, water absorbing resin particle is filled in the foam framework of the spongy layer.
Existing sponge has the characteristics that water absorbing capacity is strong but water lock ability is poor, and water-absorbing resin has good water imbibition
It is fluid after water-absorbing resin water suction but in certain fields with water lock, without fixed shape, anti-extrusion ability is poor,
Excellent water lock performance can not play in these areas, and water-absorbing resin can also foam, but need by special auxiliary agent,
Complex process, it is at high cost, and, individual water-absorbing resin can only lock the water of own vol 40~50%, not be able to satisfy high water lock
Market demands.The utility model inside spongy layer by will be modified, that is, using sponge as the abundant inside of foaming body
Gap achieves the effect that one-plus-one is greater than two, obtains water lock rate by the way that water-absorbing resin to be filled in the foam framework of sponge
Up to 90% or more compound water lock sponge, and as cold pad content, anti-extrusion ability is strong；It is big with human contact's area, drop
Temp effect is good；Surfacing, comfort level are high.
" comprising " described in the utility model, it is intended that it can also include other structures in addition to the structure, these other
Structure assigns the water lock cold pad different characteristics.In addition to this, " comprising " described in the utility model may be replaced by sealing
