Abstract
The teacher's chalk with environment protecting nano liquid material is a dust-free one. The teacher's chalk includes one pen shaft in the same color with the liquid materials, chalk tip of permeating porous fiber, pen can and writing slurry with nanometer level pigment and held in then pen shaft. The teacher's chalk is used to replace available chalk.
Description
Technical field: the present invention relates to a kind of dust-free chalk.
Background technology: existing liquid chalk uses dust big, and liquid oxious component wherein is many, and injury of human is big, should not clean.
Summary of the invention:
The problem to be solved in the present invention is: a kind of teacher's liquid chalk with environment protecting nano material is provided, reduces and pollute, the convenient use.
The scheme that the present invention solves the problems of the technologies described above is:
Teacher's liquid chalk with environment protecting nano material, its composition comprises: the body identical with the chalk pulp color, be buckled in described pen nib on one's body, cover the cap for brush on described nib, described nib is strong infiltration type pore fiber, in described the body the described chalk slurry that contains the nano-level pigment powder is housed.
Above-mentioned teacher's liquid chalk with environment protecting nano material, the composition of described chalk slurry comprises (weight proportion): pigment powder 3-10, the specification of described pigment powder is 10-100nM, the composition of described chalk also comprises: polyvinyl butyral 3-7, ethanol 48-80, polyoxyethylene carboxylic first lauryl ether ethanolamine salt 0.5-1.4 or octanol polyoxyethylene (3) the ether acetic acid third fat 5-12, isopropylcarbinol 8-20 or Virahol 20-35, the raw material of above-mentioned chalk slurry is mixed, enter shredder grinding, filtration, pressure filling in described body.
The present invention with the beneficial effect that existing technology is compared is:
1. this product is environmentfriendly products, does not have any dust, keeps the classroom with fresh air, the health of protection Faculty and Students.
2. writing is clear beautiful, and is pure bright-coloured, overcome the light illegible disadvantage of traditional chalk, can the reasonable eyesight of protecting the student.
Duration of service long, every of this product is write length more than 3000 meters, because nib and body adopt an assembled to connect, can repeatedly pour into chalk liquid, makes that this product can life-time service, does not have the chalk head, does not have waste.
4. the writing wiping of adopting the product of this prescription to write is easy, writes in month after finishing, and no matter adopts which kind of soft blackboard eraser, all can wipe clean easily, does not have vestige.
5. easy to carry, resemble volume with this product, but, carry more convenient than stronger with the writing ability of a box chalk with a pen.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
Illustrate the specific embodiment of the present invention below:
