Abstract

The invention relates to a high toughness self-cooling refrigerating gel pad and an application of the high toughness self-cooling refrigerating gel pad. The gel pad consists of inside gel and an outside gasket. The inside gel is formed by injecting a polymerizable functional monomer, biomacromolecules, a chemical cross-linking agent, a physical cross-linking agent, a filler, a preservative and a water-retaining agent dissolved in water into a mould under an oxidative-reductive initiating system. The outside gasket is a PVC (Polyvinyl Chloride) film or an aluminum foil film. The high toughness self-cooling refrigerating gel pad is characterized in that a physical and chemical compound cross-linking system is adopted so that the high toughness self-cooling refrigerating gel pad has the functions of cooling, refreshing and radiating. The gel pad provided by the invention can partially replace air conditioners, water-pillows, ice crystal gaskets, jade pads, bamboo and grass summer sleeping mats and the like. The gel pad can be applied to the fields of cooling mats for bed, afternoon nap pillows in office, cushions of automobiles, sofa or the like, mattresses, cup pads, radiating pads for notebook computers, cooling pads for pets and the like.

Description

A kind of refrigerant gel mat of certainly cooling and application thereof of high tenacity
Technical field
The invention belongs to soft wet polymer gel, nano composite material and household articles field, particularly a kind of the refrigerant gel mat of certainly cooling and application thereof of high tenacity.
Background technology
In summer, when temperature was higher than 28 ℃, the people knew from experience and to do not feel like oneself, and along with the continuous rising of temperature, this discomfort also can be more and more stronger.Open a window or blower fan because the too hot and poor effect of air-flow, very nice and cool although turn on the aircondition, but because of many situations such as long-time atmosphere draught-free causes feeling dizzy, is losing one's memory, water loss in the body, immunity degradation, directly damage healthy, i.e. so-called " air conditioner disease ".In the situation of present energy scarcity, the use of air-conditioning also causes power consumption excessive.Statistics according to investigations, the average each household of summer China used air-conditioning 10 hours every day, so one summer one family because using suitable power consumption at least 600 degree of air-conditioning, be equivalent to i.e. 416.7 days the power consumption of 1 60 watts of fluorescent lamp continuous operation 10000 hours.
The cooling articles for use have cushion, back cushion, mattress and bolster etc. except air-conditioning at present, such as various summer sleeping mats, straw mat, pillow mat etc. just separates human body and sheet, and human body is not directly contacted with the diablement fort list, but consistent with body temperature soon, the actual cooling effect that do not reach.Other has the product utilization ice block cooling, but both heavy and carry inconvenience.Also have in addition water cushion and ice crystal pad, water cushion is to utilize water to come to body temperature lowering, and after sitting, the temperature in the mat also can rise, thereby must do and change water treatment.The crystal pad is to utilize the filler saltcake, very easily makes moist, and the moisture that absorbs the after heated generation of human body is lowered the temperature, but when reaching uniform temperature, the filler in the mat also can become liquid because saltcake is heated fusion.
Hydrogel (hydrogel) is modal a kind of gel, by the effects such as covalent bond, Van der Waals force or the hydrogen bond formation three-dimensional net structure that is cross-linked with each other, can swelling in water but undissolved polymer, be the ubiquitous a kind of physical form of occurring in nature, the organs such as the muscle of human body, blood vessel, eyeball all are to be made of hydrogel.Hydrogel has good water imbibition, and the deswelling of dewatering under certain conditions, is a class set suction, water conservation, slowly-releasing is in one and develop rapidly functional high molecule material.It can absorb a large amount of water, can keep certain shape and character softness.
Utilize the high specific heat capacity of water in the high-molecular gel human body exterior heat amount can be absorbed the inside of cooling pad, three-dimensional netted molecular structure by gel is to high conductance and the diffusivity of heat, make between the heat and gel cold pad of human body, good heat exchange and conductive process have been formed between gel cold pad and the surrounding air, allow the inadequate contact-making surface of the original heat radiation of health and mattress that more effective heat radiation approach has been arranged, thereby enlarge the area of dissipation of health, form comfortable effective cooling.
Chinese patent CN2930345Y discloses a kind of way of cooling clothes, its core is the use of gel cold storage agent bag, namely at human body heat resistance weak back and position, front part of a Chinese robe or jacket shirtfront, some pouches next to the skin are set, the gel cold storage agent sack of Packed energy Reusability is set in pouch, to store up at ordinary times bag and take out and to be put in the refrigerator, will store up again when going out that cold cold storage agent is packed to be entered in the cooling clothes pouch next to the skin.Obviously its shortcoming is to need to put into refrigerator freezing before each the use, and the cooling-down effect scope is little.Chinese patent CN1068138A discloses a kind of " polyalcohol hydrogel and cold-storage device thereof ", the core of its cold-storage device is by plastic casing with take polyalcohol hydrogel as refrigerant, the outside is aided with separation layer again and forms, but this apparatus structure relative complex, and most of for medical treatment, do not have in addition the feature of environmental protection yet.Chinese patent CN101879148B discloses a kind of preparation method and goods thereof of bacterial cellulose hydrogel temperature-reducing plaster, mainly be to soak in certain density aqueous gelatin solution through processing the bacteria cellulose aquagel film that reaches medical grade, realize the cooling effect by adding borneol and menthol.Chinese patent CN102532767A discloses a kind of Water-based cooling material and preparation method thereof, and this Water-based cooling material comprises hydrogel and microcapsules of storing energy through phase change.
To sum up analyze, the hydrogel of report all need add exterior material at present, realizes cooling function such as microcapsules and borneol etc., does not have from cooling function, and do not point out whether gel has the characteristics such as pliability, and good pliability is to the important realistic meaning of having reused of product.Certainly the refrigerant gel mat of cooling of a kind of high tenacity of the present invention does not add outside cooling medium, have from cooling function, and pliability is high, can draw, curved and turn round, can unlimitedly reuse.
Summary of the invention
