Description
Technical field
The invention discloses the preparation method of a kind of odorlessness opaquing fluid, belong to opaquing fluid preparing technical field.
Background technology
Opaquing fluid, also known as " correcting fluid ", " correction fluid ", " rewriting liquid ", is a kind of common stationery, and white opaque pigment is coated with
To hide wrongly written character on paper, can the most again write after drying up.In nineteen fifty-one by American's BETTY BOOP Naismith lattice Lay
Nurse is invented.Main component is trichloroethane, hexahydrotoluene, hexamethylene three kinds, and power and the concentration of its toxic hazard are directly proportional.
Opaquing fluid is a kind of white opaque pigment, is coated on paper to hide wrongly written character, can the most again write after drying up.
Correction fluid is packed by ampoule traditionally, and the foamed plastic of the subsidiary whiskbroom of bottle cap or triangle is immersed in correcting fluid
Face.In recent years the correction fluid that pen type occurs is started, equipped with spring inside pen.By nib by pumping out correcting fluid on paper, this ratio
That sweeps type more can be coated with out correction fluid fifty-fifty, also easily will not dry up as bottled.
Due to correction fluid volatility high (that is dry speed is fast), unspent correction fluid should build bottle cap in time,
The liquid of the most remaining thickness in order to avoid evaporating in bottle and can not use.Therefore dilution would generally incidentally be sold by correction fluid manufacturer
Agent.Correction fluid, before invention word processor, allows typewriting or writing become convenient.
Although opaquing fluid is really very convenient, but it has serious hazardness, and the opaquing fluid on market itself has portion
Dividing poisonous chemical substance, these materials are the most volatile, are free in air, after being sucked by human body, can cause chronic poisoning, meeting
Cause dizziness nauseating, sleepy, be slow in action, when suction volume is too much, it is also possible to cause general malaise, tic, dyspnea, rob
Rescue and life will be caused serious harm not in time.
Summary of the invention
The technical problem that present invention mainly solves: there is poisonous chemical substance for existing opaquing fluid, these materials
The most volatile, it is free in air, after being sucked by human body, the problem that human body can be worked the mischief, it is provided that a kind of odorlessness correction
The preparation method of liquid, the method adds Ammonium persulfate. heating after microwaved to potato starch and deionized water, and regulation is mixed
Add dicyandiamide after closing liquid pH and again regulate pH, obtain cross-linking modified Oxytarch gluing agent, the powder made by zinc oxide subsequently
End and deionized water, dodecylbenzene sodium sulfonate, titanium dioxide stirring ball-milling, the white slurry obtained and polyacrylate dispersion and
Above-mentioned adhesive etc. be uniformly mixed through ball milling odorlessness opaquing fluid, preparation method of the present invention is easy, and raw material is
Non-toxic material, with water as primary solvent, opacifying property good, prepared opaquing fluid odorlessness, human body will not be produced by life-time service appoints
What toxic and side effects, has broad mass market prospect.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
