It is made by feeding, release, carding, netting, carding, spreading, dipping, drying and rolling of the cotton type chemical synthetic fiber. It can be used for the vacuum multi layer isolation structure for deep cold fluid transportation. It has fine low temperature isolationfeature, with fine softness and anti stretch, free from pollution, extensive in application, low in transportation cost.
Description
(1) technical field
The present invention relates to a kind of low-temperature thermal insulation paper, also relate to a kind of preparation method and application thereof of described low-temperature thermal insulation paper.
(2) background technology
Be usually used in heat-insulating material in the vacuum multi-layer insulation structure of cryogenic liquid storage-transport vessel and supporting pipeline thereof at present, a kind of is glass cloth, is exactly paper such as product as an alternative such as cigarette paper with other in addition.Because the glass fiber of nonwoven glass cloth needs to add wax or other grease to prevent fiber adhesion each other in the fiber drawing process, so need pass through the high temperature ungrease treatment in the time of in using multiple layer heat insulation structure, in case treatment process goes wrong or handles misoperation, will occur that venting rate under the vacuum increases and the performance that influences product, and in actual use because fibre diameter is thicker, easily make fiber enter the pore of human body and health is itched, produce, operate and bring a lot of uncertain factors and difficulty thereby give, and the integrated cost height; Though and use other paper such as the trouble that can save degreasing such as cigarette paper, but high-and low-temperature resistance (high temperature easily make paper aging by force and low temperature easily makes the paper embrittlement) not, some chemical substances of adding in the paper production process can have influence on last vacuum, thereby influence properties of product.
(3) summary of the invention
Technical problem to be solved by this invention is to provide a kind of easy to use, low-temperature thermal insulation paper that heat-insulating property is good.
Technical problem to be solved by this invention also is to provide a kind of preparation method of described low-temperature thermal insulation paper.
Technical problem to be solved by this invention also is to provide a kind of application of described low-temperature thermal insulation paper.
Described low-temperature thermal insulation paper, described low-temperature thermal insulation paper adopt cotton type chemical synthetic fiber to be shaped through the mode of the dry method of paper-making; Described low-temperature thermal insulation paper quantitatively be 5～14g/m
2, thickness is at 0.04～0.09mm.
Preferably, the line density of described cotton type chemical synthetic fiber is 1.1～2.5dtex.
Preferably, described cotton type chemical synthetic fiber is a viscose rayon.
Preferably, described cotton type chemical synthetic fiber is a polyster fibre.
Preferably, adopt polyvinyl alcohol as adhesive in the described forming process.As sizing material, the venting rate under the vacuum is very little in use can to guarantee product, and can keep condition of high vacuum degree (10 with polyvinyl alcohol
-3More than the Pa) for a long time.Can adopt the mode of the dipping vinyl alcohol hydrosol in the forming process, also can be earlier that fibrous polyvinyl alcohol and chemical synthetic fiber is compound, use the mode of water retting again.
The preparation method of described low-temperature thermal insulation paper comprises: with cotton type chemical synthetic fiber through feeding intake, rolling promptly gets described low-temperature thermal insulation paper after the shredding, combing, folded net, combing, lapping, dipping, oven dry.
Preferably, described preparation method comprises following sequential steps:
(1) it is online cotton type chemical synthetic fiber to be thrown into feeding;
(2) deliver to opener through thick shredding after wind and carry out shredding again;
(3) send into the carding machine carding;
(4) evenly fold fleece through net folding machine;
(5) be paved into the uniform fibers net with the carding machine combing;
(6) with fleece continuously through containing the immersion system of the polyvinyl alcohol hydrosol of concentration 0.1～5.0%, fleece is soaked into behind the sizing material with the squeezing rod is crowded removes a certain amount of sizing material;
(7) use many cylinder drieds again, get product with batching the device rolling.
Again preferably, in the step (6), the concentration of the polyvinyl alcohol hydrosol is controlled at 1.5%.
Low-temperature thermal insulation paper of the present invention can be used for the vacuum multi-layer insulation structure of cryogenic liquid storage-transport vessel and supporting pipeline.Carry out compoundly with aluminium foil or aluminium plating terylene film earlier when low-temperature thermal insulation paper of the present invention uses, then compound good material be wrapped on the inner bag cylindrical shell, through bonding, tie up be inserted in after fixing outside in the courage, be evacuated down to 10 after airtight
-4About Pa, thereby convection current, conduction and the radiation that can completely cut off heat make the insulation effect of equipment reach optimum comprehensively.
The beneficial effect of low-temperature thermal insulation paper of the present invention is:
1. low-temperature thermal insulation paper of the present invention can be low temperature resistant to-269 ℃, high temperature resistant to 180 ℃, heat-insulating property is good, convection current, conduction and the radiation that can completely cut off heat comprehensively, make the insulation effect of equipment reach optimum, venting rate under vacuum is very little in addition, can effectively keep condition of high vacuum degree, thereby guarantees that insulation effect is long-term, stable;
2. the present invention is the toilet roll series products, when reality is used, can satisfy with aluminium foil or aluminizer compound tense continuously, the requirement of mechanization; This product thickness is 0.04～0.09mm only simultaneously, and compound with it aluminum foil thickness also only is 0.006～0.007mm, has good flexibility and certain tension stress, and to the profiling arbitrarily of different contoured surface, construction is simple, and is time saving and energy saving;
3. this product is to non-stimulated, the not damaged of human body (as skin, face etc.), to environment without any pollution; 4. the present invention does not have corrosion to hardware, use the back indeformable, do not ftracture, not efflorescence, non-foaming, do not come off, environment for use is a vacuum, can effectively guarantee the service life of product;
5. product of the present invention removes the vacuum multi-layer insulation structure China and foreign countries that are used for cryogenic liquid storage-transport vessel and supporting pipeline, also can be used for the Cryo Heat Insulation in fields such as low-temperature superconducting, Aero-Space, is widely used;
6. very thin thickness of the present invention, quantitative also very low, when reaching same insulation effect, the spacing that can dwindle inside and outside courage greatly, thus save outer courage material, the recyclable utilization again of consumable material, cost of transportation is low.
