Abstract
The invention provides Haiou-stone-series negative ion additives prepared from Haiou-stone-serious ultra-fine powder capable of releasing negative ions by a doping and blending method and an aqueous polyurethane coating capable of releasing negative ions, wherein the aqueous polyurethane coating capable of releasing negative ions is successfully prepared from the following raw materials by weight: 0-100 of polyester polyol, 0-100 of polyether polyol, 5-85 of diisocyanate, 0.1-20 of negative ion additive, 0-10 of auxiliary agent and 0.1-3 of catalyst. The Haiou-stone-serious ultra-fine powder capable of releasing negative ions has the advantages of good dispersivity in combined materials and almost no process defects during processing.
Description
Technical field:
The invention belongs to fields such as material, chemical, furniture, automobile, boats and ships, leather, health, environmental protection.
Background technology:
Along with the raising day by day of human civilization, activity in production, particularly industrialization degree, pollute also more and more seriously, particularly people thirst for graceful environment, so various environment-friendly materials, functional materials arise at the historic moment.Negative ion is to the more and more attention that are subjected to the scientific worker of the living environment of improving people.Negative aeroion is called " air VITAMIN " or " long-living element ", and the anion number of keeping health of people is: 1000-2000/cm
3Long-term in modernized air-conditioning and construction thing the people of live and work; usually can feel unhappiness, lethargic sleep, weak, nauseating, headache, dizzy dusk; working efficiency and physical integrity obviously descend, and studies show that, cause the concentration of negative ion in the reason of this phenomenon and the air closely related.The continuous progress with hi-tech of developing rapidly along with Materials science, people just constantly develop, develop coating, fiber, fabric, dress ornament and spring function material etc. with negative ion-releasing function, and the release anion material with nourishing function is more and more paid attention to by people.
Discover through us: Hai Ousi series anionic additive has certain deodorizing, inhales flavor; Antibiotic, diseases prevention; Discharge the nourishing function of negative ion.We adopt coarse reduction, the superfine grinding of air-flow method and wet grinding process combined route, and natural crystal is prepared into micron-sized ultra-fine micropowder.This modification ultra-fine micropowder have functions such as discharging negative ion, sterilization, deodorizing, can be widely used in the macromolecular materials such as coating, rubber, plastics.The present invention adopts rare talent's series superfine powder capable of releasing negative ion, formulated extra large Ou Shi series anionic additive by doping and blending method, join in the macromolecular materials such as urethane, polyethers, polystyrene, polyvinyl chloride, successful production have an aqueous polyurethane coating that discharges negative ion.The ultra-fine micropowder of extra large Ou Shi series capable of releasing negative ion has extraordinary dispersiveness in the combination material, do not have any defective workmanship in the course of processing basically.
After the ore superfine grinding that has nanoporous, further grind modification initiative Cheng Hai Ou Shi series anionic additive again, add in the aqueous polyurethane coating, can discharge negative ion, and do not influence other performance of coating, people's health is highly profitable.The negative ion concentration of releasing anion water based polyurethane coating is about 1.5 * 10
3Individual/cm
3, reached the above concentration of town park negative ion.Just be equivalent to the concentration of people in Urban Parks stroll, releasing anion water based polyurethane coating can be followed the people at one's side at any time, very extensively: as furniture, automobile, boats and ships, leather, interior exterior wall etc. and other material.Like this, just can make the people natural space that is enclosed in negative ion constantly, play the mankind have been brought into the colory living space of following that negative ion is arranged constantly, create tasteless automobile, tasteless environment etc.
Summary of the invention:
Invention prescription: polyester polyol: 0～100; Polyether glycol: 0～100; Vulcabond: 5～85; Anionic additive: 0.1～20; Auxiliary agent: 0～10; Catalyzer: 0.1～3.
Technology: the anion far infrared rays fine powder is dried, add vector resin, coupling agent, dispersion agent then, carrying out high speed mediates, in reactor, the negative ion of reaction formation does not under certain conditions have the water-polyol system with the functional polymer that discharges negative ion and polyester polyol or polyether glycol.Then negative ion is not had the water-polyol system and mix with vulcabond and auxiliary agent and react, after reacting completely, the deionized water emulsification still that product is added high-speed stirring carries out emulsification.After emulsification is finished, can filter and package.Auxiliary agent comprises: emulsifying agent, chainextender, linking agent, viscosity-depression agent, neutralizing agent etc.Discharging negative ion is 1500/cm
3More than.
Embodiment: raw material: polyether glycol: 100; Methyl vulcabond (TDI): 90; Anionic additive: 10; Dimethylol propionic acid (DMPA): 1.5; Acetone: 15; 1,4-butyleneglycol: 15; TriMethylolPropane(TMP) (TMP): 3; Triethylamine (TEA): 2; Stannous octoate: 2; Deionized water.
Building-up process:
(1) synthetic prepolymer: the polyether glycol adding is equipped with in the four-necked bottle of agitator, thermometer, prolong, at 90～95 ℃, dehydration reaction 1.5～2h under the vacuum tightness 0.09MPa condition.After the dehydration, add Hai Ousi series negative ion powder, being deployed into negative ion does not have the water-polyol system.Remove reliever and prolong then, change return line, under 40 ℃ of conditions, add TDI, keep the follow-up temperature of continuing rising of reaction 1h when being warming up to 60 ℃.
(2) introduce the wetting ability chainextender: add DMPA under 78 ℃ and carry out hydrophilic chain extending reaction, lower the temperature behind the 40min.Add proper amount of acetone in the reaction process with control performed polymer viscosity.
(3) further chain extension, crosslinked: 70 ℃, add internal crosslinker TMP and small molecule chain extender 1, the 4-butyleneglycol is kept reaction 1h, reduces temperature of reaction then.This process viscosity may occur and strengthen, thus should add acetone control viscosity, in case gel.
(4) neutralization, emulsification: adding TEA below 40 ℃, neutralization reaction is taking place and continue 10min, discharging adds deionized water emulsification under high speed dispersion is sheared, and continues to stir 30～60min and can obtain the negative ion aqueous polyurethane coating.
