Description
Technical field
The present invention relates to a kind of heat conduction thigmonasty latex product and preparation method thereof and its purposes.
Background technology
At present emulsion products such as gloves, conduit, condom still adopt and cooperate technology that natural emulsion solidifies by dip forming and latex to produce.Gloves, conduit, condom that this class material is made have the inherent insulativity, and this inherent characteristic has caused the heat passage of poor efficiency, and its result has reduced user's thigmonasty.

Nanoparticle has big specific surface area and high specific heat, and it is that it is added in the rubber to reach the filler reinforcement effect that more patent is arranged at present, improves the latex product capacity of heat transmission but seldom there is public technology to use it for.Yet the surfactivity of nano particle makes them be easy to reunite, and nanoparticle evenly, stably is dispersed in the rubber medium, is key issue to be solved.The present invention mixes nano particle earlier with water, add promoting agent or dispersion agent, then by ultrasonic vibration, regulator solution pH value, nanoparticle surface Zeta potential absolute value is increased, and stops intergranular reunion with the Coulomb repulsion effect.Again with treat sulfurized natural emulsion uniform mixing, obtain the heat conduction latex product of carbon nanotubes by conventional molding procedure.
Summary of the invention
The objective of the invention is to thermal heat transfer capability deficiency, a kind of heat conduction thigmonasty latex product and preparation method are provided, and disclose the purposes of this heat conduction thigmonasty latex product at existing latex product.
A kind of heat conduction thigmonasty latex product is characterized in that containing in the described latex product nano level Au, Ag, Cu, Al, CuO, ZnO, MgO, Al
2O
3, TiO
2, SiO
2, SiC, AlN, BN particle a kind of or mixture that they are several.These nano level metals, metal oxide and nonmetallic compound have good conduction, thermal conduction characteristic, and the thermal conducting function of latex product is significantly improved, thereby satisfy the service requirements of heat conduction thigmonasty.Because natural emulsion itself, with nanoparticle mixing process in be easy to the phenomenon of flocculating takes place, the present invention will realize nanoparticle homodisperse in natural emulsion.The method that adopts is earlier nano particle to be mixed with water, adds promoting agent or dispersion agent, passes through ultrasonic vibration, regulator solution pH value then, prepares the stabilized nano particle suspension, again with treat sulfurized natural emulsion uniform mixing.Usually the dispersion stabilization of nanoparticle mainly is subjected to the Coulomb repulsion function influence, these nanoparticle surface are electronegative, when pH value＜2, the Zeta potential absolute value minimum of particle surface, electrostatic repulsion between the particle is not enough to contend with interparticle magnetism, particle Brown motion makes the particle coagulation that runs foul of each other, and corresponding dispersion stabilization is very poor; Along with the pH value increases, the Zeta potential absolute value of particle surface constantly increases, the electrostatic repulsion that forms between the particle, be enough to stop owing to attract each other between the particle that Brown motion produces and collide, bigger electrostatic repulsion also makes particle relatively independent, and interparticle distance increases, thereby has surpassed the distance that hydrogen bond action takes place between the particle, further reduce particle and assembled mutually and settled chance, reached the purpose of improving the nanoparticle dispersion stabilization.For example, when heightening pH value made the Zeta potential absolute value higher, the Coulomb repulsion effect in the suspension between the particle was stronger, and the particle of reunion is opened the back than easy stably dispersing by means of mechanical force, and is better dispersed.But the pH value continues to increase, because adjusting agent concentration, the pH value increases, and compression double electric layer thickness, the Zeta potential absolute value has the trend of reduction, and electrostatic repulsion reduces to cause dispersed variation.So pH value has a stagnation point, when this stagnation point, this suspension liquid dispersed best.Contain nanoparticle heat conduction thigmonasty latex product through what this processing obtained, also have functions such as sterilization, sterilization, deodorization.
Above-mentioned heat conduction thigmonasty latex product, wherein nanoparticle is preferably the Cu particle.
The preparation method of the heat conduction thigmonasty latex product that the present invention proposes, contain following steps successively:
The preparation of step 1. nanoparticle suspension
Nanoparticle is mixed with dispersion agent, deionized water, ultra-sonic dispersion is made into the suspension of nanoparticle, regulates the pH of suspension value to 8-11 with ammoniacal liquor, citric acid solution, suspension nano grain surface Zeta potential absolute value is increased, stop intergranular reunion with the Coulomb repulsion effect.
Present method invention is added nanoparticle and is dispersed in the latex, because nanoparticle has big specific surface area and high specific heat, when playing the filler reinforcement effect, significantly improves the exchange capability of heat of latex product.Nanoparticle has characteristics such as small-size effect, quantum size effect, surface effects and macro quanta tunnel effect, the little reactive force such as van der waals forces, the electrostatic force etc. that act on the particle all be can not ignore, and chemical property of reactive force and size of particles, shape, surface property, particle and rubber phase and temperature etc. are closely related slightly for these.Little reactive force of nanoparticle and consequent vibration cause the effect between interparticle effect and particle and rubber phase, but the energy-handling capability of reinforcing rubber.Particularly, when the yardstick of nano particle near or during less than the mean free path of phonons of crystalline material, vital role has been played on the border, the lattice vibration ripple is subjected to the strong scattering at nano particle interface, makes heat passage be great-jump-forward and non-confinement.If the nano particle spacing is little below 1nm, the rubber rete contact that two particle surfaces adhere to even overlap, such two nano particles are equivalent to direct contact, hot short circuit occurs, greatly reduce thermal resistance, increased the effective thermal conductivity of rubber matrix.Yet the surfactivity of nano particle makes them be easy to reunite, and nanoparticle evenly, stably is dispersed in the rubber medium, is key issue to be solved.The present invention mixes nano particle earlier with water, add promoting agent or dispersion agent, then by ultrasonic vibration, regulator solution pH value, nanoparticle surface Zeta potential absolute value is increased, and stops intergranular reunion with the Coulomb repulsion effect.In this step, the pH value the best of being regulated is 9, and the suspension liquid of nanoparticle is dispersed best under this PH.
