Summary of the invention
The purpose of the present invention is to solve the above-mentioned problems and provides a kind of inner wall of building sustained release flowers coating and its system Preparation Method.
The purpose of the present invention is achieved through the following technical solutions:
A kind of inner wall of building sustained release flowers coating, which includes the raw material of following mass percentage content: active superfine Pollen Nano capsule 0.1-0.3%, adsorbent diatomite 1.5-2.2%, binder polyvinyl alcohol 1.2-2.5%, dispersing agent are fine Tie up element 0.6-1.2%, stabilizer xanthan gum 0.3-1.2%, filming emulsion 75-80%, remaining be water, wherein it is described activity surpass Thin pollen Nano capsule is to be coated on Nano capsule by active superfine pollen to be made, and there is slow release to be sustained flowers function naturally Energy.
Preferably, the active superfine pollen Nano capsule is made by following steps:
(1) flower is acquired during flowers full blossom, and is dehydrated in drying plant, and first dryer heats up, then feeds intake Successively progress high temperature dehydration is dry, cooling eases back and low temperature dewatering, and the flower of dehydration and drying is put into the grinding of ultrafine plant powder body Machine is ground, and active superfine pollen is obtained；
(2) using sodium alginate as wall material, using active superfine pollen as core material, active superfine flower is prepared using emulsion polymerization method Powder Nano capsule.
Preferably, dryer is warming up to 60 DEG C of stabilizations in step (1), then carries out the drying that feeds intake；High temperature dehydration drying process Temperature be 60 DEG C, the flower residence time be 50-70min；The temperature for the process that eases back that cools down is 10-20 DEG C, the flower residence time For 10-30min, the temperature of low temperature dewatering process is 35-40 DEG C, flower residence time 60-80min.
Preferably, step (2) specific steps are as follows: sodium alginate is dissolved in the aqueous solution containing emulsifier, then plus Enter active superfine pollen, keeps active superfine pollen evenly dispersed in the solution through mechanical stirring, add calcium chloride and pass through gel Reaction forms Nano capsule.
Preferably, the active superfine pollen uses the superfine powder of 800-1000 mesh.
Preferably, the adsorbent diatomite uses the diatomite of 100-300 mesh, for adsorbing the toxic gas in air And electromagnetic radiation, the binder polyvinyl alcohol, for bonding active constituent, diatomite, dispersing agent, stabilizer and lotion.
Preferably, the dispersing agent cellulose is in hydroxymethyl cellulose, hydroxyethyl cellulose or hydroxypropyl cellulose It is one or more.
Preferably, the filming emulsion be selected from acrylic emulsion, styrene-acrylic emulsion, silicone acrylic emulsion or acrylate and vinyl acetate emulsion one kind or It is a variety of.
Preferably, the stabilizer xanthan gum can play emulsification and stabilization, for active constituent and diatomite in cream Stability in liquid plays an important role, and the filming emulsion plays protection wall.
A kind of preparation method of inner wall of building sustained release flowers coating, this method are as follows: weigh by mass percentage filming emulsion, Water, adsorbent diatomite, binder polyvinyl alcohol, dispersing agent cellulose, stabilizer xanthan gum and active superfine pollen nanometre glue Capsule, and be added sequentially in reaction kettle, temperature control grinding stirring obtains uniformly mixed dope for inner wall of architecture.Temperature control range is 40- 65 DEG C, grinding mixing time is 8-12h.
In the present invention, during preparing active superfine pollen, excessively mated formation set equably flower is placed on it is stainless In steel mesh belt, flower is brought into the high temperature drying area of drying machine by mesh belt, and the hot dry air that wet flower and hot-blast stove are sent carries out Convective heat exchange.During carrying out heat exchange, the moisture on flower surface and the Free water included are evaporated discharge.In high temperature In dry section, the moisture of flower 75%-80% is evaporated out.Then, flower enters the cooling tempering section that eases back, in this area In section, the flower reduced is transported to the upper of drying machine by the air-flow of air-cooler (air-cooler with certain outlet pressure) Another exit in side.For flower during being conveyed by air-cooler, temperature decline, this process is known as tempering phenomenon.Pass through cooling Tempering, the internal junction Heshui of flower, which can be shifted soon to extexine, to spread, and creates condition for next step low temperature drying.Slow During Soviet Union, the moisture of flower can reduce 3% or so.Flower eases back after dehydration by cooling, into low temperature drying section, this Zone temperatures are controlled at 35-40 DEG C or so, and flower internal junction Heshui will further be extracted evaporation, and in this section, flower is It is conveyed by one group of reciprocating sieve, is dehydrated 5%-8%, keeps flower up to standard and be discharged, which helps to maintain the activity and perfume of flowers Gas.
Active superfine pollen Nano capsule, active superfine pollen Nano capsule and adsorbent silicon is added in the present invention in coating The compounding such as diatomaceous earth, binder polyvinyl alcohol, dispersing agent cellulose, stabilizer xanthan gum and filming emulsion, coating tool obtained There are nature sustained release flowers, except formaldehyde, antimycotic antiseptic eliminate the unusual smell, anti-radiation, ageing-resistant and stain resistant function.Active superfine pollen It is coated by Nano capsule, sodium alginate is dissolved in the aqueous solution containing emulsifier, active superfine pollen is then added, through machine Tool stirring keeps active superfine pollen evenly dispersed in the solution, adds calcium chloride by gel reaction and forms Nano capsule, this Kind facilitates the slow release of flowers active constituent and fragrance by way of by active superfine pollen Nano capsule cladding, long Up to several months or several years, coating still has certain floral odor.
