The application of a kind of nano transparent heat-insulating coating on textile cloth
Technical field
The present invention relates to a kind of insulating moulding coating, the application of particularly a kind of nano transparent heat-insulating coating on textile cloth.
Background technology
Nowadays at present; Development of science and technology has rapidly been brought the convenience and the comfortableness of people's lives; Increasing heat-barrier material is widely used on building and the industrial equipment; But heat-barrier material is also narrow in relating to of field of textiles, and people are burning hot day by day to the demand with textiles heat insulation and attractive in appearance, so the market space of heat insulation textiles and prospect are comparatively wide.
Insulating moulding coating mainly comprises isolation-type insulating moulding coating, reflection type thermal insulation coating and radiation type heat-insulation coating.Though isolation-type insulating moulding coating effect is better, the application on textiles is not too practical, because this type of coating belongs to the coating of coloured muddiness; After coating on the cloth, can have a strong impact on the outward appearance and the feel of cloth; For example Lv Haitao (patent publication No.: CN101648794) disclose a kind of dry-type heat-insulating waterproof coating, this kind coating has certain effect of heat insulation on fabric, but since coating this as white; If cloth is non-white, will influence the color of cloth itself after the coating; Radiation type heat-insulation coating, is also treated more in depth to study though significantly technology is very complicated for effect with the external distribute heat of thermal-radiating form.The basic principle of nano transparent heat-insulating coating is to utilize the nano semiconductor material that mixes that infrared light is absorbed and reflects, thereby reaches not only heat insulation but also transparent effect.At present; This type of coating is used on building glass and the precision instrument mostly; Zhao Shilin etc. (patent publication No.: CN 1563231A) disclose a kind of by the ITO powder, nano ATO, the coating that auxiliary agent and diluent are formed; Experiment finds that this kind coating is coated in glass surface certain effect of heat insulation is arranged, but in textiles, come off easily and effect of heat insulation limited; (patent publication No.: CN 102241937A) disclose a kind of POSS modified water-soluble nano transparent insulating coating and preparation method thereof, this kind technology comparatively suitable commercial production of complicacy and cost is higher for Dai Lizong etc.
Summary of the invention
Influence the problem of cloth color and luster in order to solve heat insulating coat in the past, the present invention uses nano ATO and nano-TiO
2Two kinds of nanometer heat insulation materials combine with the SILICONE COATING AGENT methyl-silicone oil, make a kind of nano transparent heat-insulating coating.
The present invention realizes in the following manner:
A kind of nano transparent heat-insulating coating, component is in the described coating: represent nano ATO and nano-TiO with mass percent
2Amalgam is 20~40%, DMF is 20~35%, PEG400 is 2.5%, 46
#The heat storing and heat preserving capsule be 3% with methyl-silicone oil be 15~45%.Wherein nano ATO and nano-TiO
2Mass ratio be 2: 1,1.5: 1 and 1: 1; Nano ATO and nano-TiO
2Amalgam is 30%; DMF is 30%; Methyl-silicone oil is 35%.
Described heat insulating coat preparation method comprises following step:
(1) preparation of nanometer mixed slurry: elder generation is with the nano ATO and the nano-TiO of aequum
2Mix by a certain percentage, mixed-powder joins in the solvent DMF, uses magnetic stirring apparatus to carry out magnetic agitation 30min, promptly makes the nanometer mixed slurry;
(2) get a certain amount of methyl-silicone oil, join lentamente in the above-mentioned nanometer mixed slurry, continue to open magnetic stirring apparatus, stir 20min, promptly make the mixed coating agent;
(3) in above-mentioned mixed coating agent, add dispersant and heat storing and heat preserving capsule, and carry out ultrasonic dispersion 2h, promptly make the nano transparent heat-insulating coating agent.
Nano transparent heat-insulating coating agent to preparing carries out coating to cloth, and the process of coating is the single face coating for scraping the skill in using a kitchen knife in cookery, the cloth that coating is good is dried 2min down at 150 ℃, and use coated fabric heat-proof quality tester to carry out the heat-proof quality test.
Advantage of the present invention:
1. have the infrared effect of good obstruct owing to nano ATO, and nano-TiO
2The ultraviolet-resistant effect also better, effectively intercept infrared and ultraviolet so both mix physical efficiency, the effect of heat insulation of coating strengthens.
2. use SILICONE COATING AGENT to combine, make that nanometer thermal insulation coating is a transparence, solved the problem that heat insulating coat in the past influences the cloth color and luster with nanometer heat insulation material.
3. technology of the present invention is simple, is easy to produce, and pollution-free, be a kind of technology of environmental protection.
