Description
[technical field]
The present invention relates to material technology, especially a kind of complex mesoporous material with excellent insulation effect.
[background technology]
The heat-insulation and heat-preservation material can be widely used in fields such as various Industrial Stoves, heating and ventilating equipment, building, carrier vehicle and naval vessel.Common heat-insulation and heat-preservation material has multicellular glass, Calucium Silicate powder, expanded pearlite cotton, fiberglass products, urethane and Expandable Polystyrene (EPS) plate etc.The heat-insulation and heat-preservation principle of these materials is all basic identical, promptly introduces more small hole in material; Its thermal conductivity is usually than higher, all greater than 0.019W/ (m.K), such heat insulation and preservation effect still is not very desirable for a lot of use occasions, and making needs heat insulation equipment, pipeline etc. in use to lose a large amount of thermals source, the waste resource increases cost.The beginning of this century, U.S. MONSANTO company uses silica aerogel to be used for adiabatic mould material; Used regenerated fiber or asbestos etc. compound with silica aerogel afterwards, the thermal conductivity of this type of fibre composite can be low to moderate 0.013W/ (m.K).The heat-proof quality of vacuum heat-insulation VIP plate is relatively good, its thermal conductivity can reach 3.0mW/ (mK), but vacuum heat-insulation VIP plate needs to form the vacuum insulation space than low vacuum in making processes, it is relatively more expensive to form this vacuum insulation space cost, and also comparatively difficulty and cost are very high in use will to keep this vacuum insulation spatial vacuum tightness.
[summary of the invention]
Technical problem to be solved by this invention provides a kind of complex mesoporous material with excellent insulation effect.
For solving the problems of the technologies described above, the invention provides a kind of complex mesoporous material, this complex mesoporous material by mesoporous material and tackiness agent by weight 20: 80-90: 10 are composited; Perhaps by mesoporous material and fiber by weight 10: 90-90: 10 are composited; Perhaps by mesoporous material and tackiness agent, fiber three by weight 1: (0.1-3): (0.1-9) be composited; Perhaps constitute the vacuum space, ccontaining mesoporous material in the vacuum space by gas barrier properties film material or gas barrier properties sheet material; The porosity of the used mesoporous material of complex mesoporous material of the present invention is 40%-90%.
Complex mesoporous material adhesive therefor of the present invention can be one or both the mixing in polymer binder and the inorganic adhesive.The used fiber of complex mesoporous material of the present invention can be one or more the mixing in natural fiber, inorganic fibre or the macromolecular fibre.Situation for mesoporous material and fiber composite, mesoporous powder can be made into slurries with solvent (as ethanol) after grinding, be laid immediately in the container after fiber or fibre product (as cloth, felt, band, cotton etc.) cut according to size, copy after the immersion and get fiber or the fibre product that is soaked with mesoporous material, oven dry; Can get-drying course through repeatedly soaking-copying; Also can will prepare the precursor of mesoporous material and fiber or fibre product and be combined with each other, and adopt precursor this complex body to be handled then, obtain the complex mesoporous material that constitutes by mesoporous material and fiber to the technological process of mesoporous material by said process.Complex mesoporous material of the present invention has excellent insulation effect, and thermal conductivity is lower than 0.009W/ (mK).
Insulation effect has much relations with the pore in the thermal insulation material.The air main component that is present in the pore is oxygen and nitrogen.In the complex mesoporous material of the present invention, aperture size is all below 50 nanometers, free path less than nitrogen and oxygen molecule motion, and the mesoporous material aperture is even, pore size distribution is narrow, arranges in order in the hole, so the air molecule in the mesoporous material can not convection current, mesoporous hole internal state and vacuum are very approaching, thereby the transmission of heat by convection of complex mesoporous material of the present invention when heat-insulation and heat-preservation reduces significantly.When mesoporous material and fiber composite, and under the situation of mesoporous material and tackiness agent, fiber composite, mesoporous material itself has excellent heat-insulating property, and fiber also is a lagging material; Fiber can play strengthening action to matrix material, thus the strengthening action of fiber can reduce thermal insulation material in the heat-insulation and heat-preservation process because of suffering thermal stresses impact to produce the possibility that causes heat-insulating property to reduce than macrovoid or crack; In addition, fiber in the matrix material is equivalent to increase a lot of heat-reflecting plane of reflection on the thermal conduction direction in heat conducting path, these plane of reflection have the effect of heat to a plurality of different directions reflections, the heat reflection of a plurality of different directions makes the heat insulating ability that material is good, therefore, mesoporous material and fiber composite, and mesoporous material and tackiness agent, fiber composite fiber and mesoporous material compound after, resulting mesoporous/fibre composite has more excellent heat-insulating property.Tackiness agent can be polymer or mineral-type tackiness agent.
The used mesoporous material of complex mesoporous material is the mesoporous material of hydridization.Adopt the mesoporous material of hydridization can improve performances such as high temperature resistant, corrosion-resistant, strengthen suitability environment for use.
The used mesoporous material of complex mesoporous material is the mesoporous material of handling through modification.Modification is handled by the replacement of material surface group can play the effect that reduces thermal conductivity.
The hybrid material of handling through modification is the hydrophobic mesoporous material through surface modification treatment, hydrophilic mesoporous material or mesoporous material metallo-chelate.
Be doped with in getter and the opalizer one or both in the complex mesoporous material.Getter makes the air (heat-conduction medium) in mesoporous reduce, and insulation effect is further improved; Can block infrared radiation heat transfer.
Complex mesoporous material constitutes the vacuum space by gas barrier properties film material or gas barrier properties sheet material, ccontaining mesoporous material in the vacuum space; The vacuum tightness of vacuum space is lower than 30Pa and gets final product in this complex mesoporous material, the desired vacuum tightness of conventional vacuum heat-insulating plate (VIP) is 10Pa, the vacuum tightness that realizes this complex mesoporous material requirement comparatively speaking is more or less freely, and cost is also lower, and can not use getter.
Complex mesoporous material of the present invention can be applicable to heat-insulating material, has excellent insulation capacity.
The invention has the beneficial effects as follows: complex mesoporous material of the present invention has excellent insulation capacity, and thermal conductivity is lower than 0.009W/ (mK); With respect to the suitable thermal insulation material of thermal conductivity in the prior art, complex mesoporous material of the present invention is simple in structure, and is easy to manufacture, and cost lowers.
