Abstract
The present invention discloses a dust-free chalk liquid, which is characterized by comprising, by weight, 66% of edible alcohol, 3% of a resin, 1% of butyl ether, 5% of purified water, 20% of titanium dioxide powder, and 5% of talc powder. The production method comprises: adding 5% of purified water, then adding 43% of edible alcohol, adding 1% of butyl ether to moisturize so as to lock the moisture of the liquid and prevent evaporation, stirring for 30 min, slowly adding 3% of a resin during the stirring process, uniformly stirring to prepare a glue, taking 50% of the total amount of the prepared glue, adding titanium dioxide tower and talc powder, adding to a dispersing machine to grind for 20 min, adding the remaining prepared glue and the remaining 23% of the alcohol, and stirring for 25 min so as to complete the production of white chalk liquid. Compared with the dust-free chalk liquid in the prior art, the dust-free chalk liquid of the present invention has the following advantages that: the dust-free chalk liquid is filled into the free-dust pen, can be attached on a variety of smooth surfaces or blackboards, and has characteristics of easy writing, clear writing, easy erasure, no dust production, safety, environmental protection, and easy use.
Description
Technical field
The present invention relates to environmental protection teaching field, specifically relate to Dust-free chalk liquid of a kind of alternative teaching chalk and preparation method thereof.
Background technology
General chalk is all disposable, frangibility, and dust is serious, or the disposable no-dust chalk of solid shape, actual use in consumption large, fragile, cost is high.
Summary of the invention
Object of the present invention is exactly for above-mentioned deficiency, provides a kind of Dust-free chalk liquid, is suitable for the impart knowledge to students environmental protection of application, the Dust-free chalk liquid of easily wiping.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of Dust-free chalk liquid, is characterized in that: it is made up of following component by weight percentage: edible ethanol: 66%, resin 3%, butyl ether 1%, pure water 5%, titanium dioxide 20%, talcum powder 5%.
Also comprise food dye in the component composition of described Dust-free chalk liquid, food dye can select any one color.
Dust-free chalk liquid of the present invention is divided into without odor type and has odor type two kinds, also comprises the food flavour of 0.5 ~ 1% the dust-free chalk fluid component of odor type in being made up of.
Preferred above-mentioned formula ratio, its preparation method comprises the following steps: first add pure water 5%, then adds edible ethanol 43%, prevents alcohol from volatilizing; Add butyl ether 1% and carry out moisturizing, pin the moisture of liquid, prevent volatilization, stir 30 minutes; In whipping process, slowly add resin 3%, slowly add resin, the group of having prevented, uniform stirring makes glue; Get and make 50% of glue total amount of liquid, add titanium dioxide and talcum powder and enter dispersion machine and carry out grinding 20 minutes; Add the glue of remaining 50% again, stir 25 minutes; If the chalk liquid of white just completes making; If pastel liquid, then add food dye and 23% remaining alcohol again, stir 10 minutes; If there is the chalk liquid of odor type also to need to add the food flavour of 0.5 ~ 1%, stir 5-10 minute.
Effective effect of the present invention is: Dust-free chalk liquid of the present invention is filled in no-dust chalk, and can adhere on various smooth plane or blackboard, be convenient to write, writing is clear, easily wipes, and does not produce dust, and safety and environmental protection is easy to use.
