Abstract
The environmental protection erasing rubber of the present invention, material formula is: vinyl chloride resin slurry 100-120 part, dioctyl phthalate 80-100 part, adipic acid dioctyl ester 20-30 part, calcium carbonate 13-18 part, titanium dioxide 1-3 part, stabilizer 3-5 part, surfactant 1-2 part, N-methyl nitrosourea 60 parts, foaming agent 10 parts composition；Having raw material to be easy to get, cost is low, the advantage that environmental protection free from extraneous odour, erasing person's handwriting are effective.
Description
Technical field
The invention belongs to a kind of erasing rubber.
Background technology
Erasing rubber (English: eraser (U.S.), rubber (English, Australia)), also known as rubber, rubber erasers, rubber, wiping paper glue, rubber erasers cloth, wiper, eraser, for wiping pencil stationery of ink marks on paper away.How white they are, brown or pink, but along with new raw material occurs, present erasing rubber can be any color.The main composition material of erasing rubber is rubber.The erasing rubber that some prices are higher then contains plastic cement composition.The apparatus of wiping chalk or blank person's handwriting is commonly referred to as and whitewashes or (black) plate.Erasing rubber now is of a great variety, to suit different needs.The afterbody of some pencil is provided with a slight erasing rubber.Mostly these erasing rubbers are peach, and surface is smooth colloid.They all have a good performance in most occasion, but paper of sometimes also making dirty.If putting forth effort to weigh very much, erasing rubber also has an opportunity to stave paper.After person's handwriting is wiped, erasing rubber can stay residue on paper.If cleaning is not good at, these residues can be left a trace on paper.Another kind of erasing rubber is the brown erasing rubber that artist is conventional, and with softness, coarse rubber is made.Its design is convenient to wipe large-area vestige, and will not stave paper.But this erasing rubber can not wipe person's handwriting very effectively and accurately.All there is the pungent deficiency of volatilization in current erasing rubber.
Through China's publication retrieval, do not find the scheme identical with present patent application.
Summary of the invention:
It is an object of the invention to；A kind of environmental protection erasing rubber is proposed.
The environmental protection erasing rubber of the present invention, it is characterized in that: by weight, material formula is: vinyl chloride resin slurry 100-120 part, dioctyl phthalate 80-100 part, adipic acid dioctyl ester 20-30 part, calcium carbonate 13-18 part, titanium dioxide 1-3 part, stabilizer 3-5 part, surfactant 1-2 part, N-methyl nitrosourea 60 parts, foaming agent 10 parts composition.
The environmental protection erasing rubber preparation method of the present invention, it is characterised in that: by weight, Corvic is starched 100-120 part, dioctyl phthalate 80-100 part, adipic acid dioctyl ester 20-30 part, calcium carbonate 13-18 part, titanium dioxide 1-3 part, stabilizer 3-5 part, surfactant 1-2 part, N-methyl nitrosourea 60 parts, after mixing, adds foaming agent 10 parts, at 120 DEG C, stirring is warmed up to 160 DEG C after mixing 5-10 minute, pressing mold molding, obtains the environmental protection erasing rubber of the present invention.
Compared with prior art it provides the benefit that the present invention: having raw material and be easy to get, cost is low, the advantage that environmental protection free from extraneous odour, erasing person's handwriting are effective.
