Abstract
The invention embodiment relates to a eraser manufacturing method, comprising blending polychloroethylene, citric acid, vinyl acetate, vinyl acetate, ethylene bisstearamide and adjuvant into a liquid material according to preset proportion and adding in a mould, baking and solidifying forming. Additionally, the invention embodiment also provides an eraser composition. The eraser with various shape, bright color and environment protection is manufactured by the eraser manufacturing method and the eraser composition.
Description
Technical field
The present invention relates to a kind of eraser manufacturing method and eraser composition.
Background technology
What eraser manufacturing method adopted at present is technology modes such as cutting, extruding, injection moulding, and by the rubber that at present existing technology and material are worked it out, it is varied that its moulding is not accomplished, it is rich and varied that its color is not accomplished yet, and not environmental protection.
Summary of the invention
Embodiment of the invention technical problem to be solved is, a kind of eraser manufacturing method and eraser composition are provided, and can produce the erasing rubber of various shapes, bright in luster and environmental protection, not only can increase entertaining in learning life, also helps people's health.
For solving the problems of the technologies described above, the embodiment of the invention adopts following technical scheme:
A kind of eraser manufacturing method comprises
Adaptation step: polyvinyl chloride, citric acid, vinyl acetate, the two hard acid amides of ethylene and auxiliary material are deployed into liquid material according to preset blending ratio;
Forming step: above-mentioned deployed liquid material is added in the mould, and the baking-curing moulding.
A kind of eraser composition, its raw material comprise polyvinyl chloride, citric acid, vinyl acetate, the two hard acid amides of ethylene, and auxiliary material.
The beneficial effect of the embodiment of the invention is:
By adopting a kind of brand-new eraser manufacturing method and corresponding eraser composition, can produce the erasing rubber of various shapes, bright in luster and environmental protection, not only can in learning life, increase entertaining, also help people's health.
The specific embodiment
The embodiment of the invention provides a kind of novel eraser composition, and the eraser manufacturing method that adopts said composition to carry out, mainly comprise: adaptation step: polyvinyl chloride, citric acid, vinyl acetate, the two hard acid amides of ethylene and auxiliary material are deployed into liquid material according to preset blending ratio; Forming step: above-mentioned deployed liquid material is added in the mould, and baking-curing moulding, become rubber after the final correction outward appearance, adopt the eraser composition and the eraser manufacturing method of the embodiment of the invention, can produce the erasing rubber of various shapes, bright in luster and environmental protection, not only can in learning life, increase entertaining, also help people's health.
With two specific embodiments eraser manufacturing method of the present invention is described below, eraser composition of the present invention is described simultaneously.
A kind of eraser manufacturing method, this method is used to produce a kind of rubber of monochrome, comprising:
Adaptation step: the liquid material that polyvinyl chloride, citric acid, vinyl acetate, the two hard acid amides of ethylene and auxiliary material is deployed into a kind of color according to preset blending ratio;
Forming step: adopt needle tube type to drip molding apparatus above-mentioned deployed liquid material and splash into mould, and the baking-curing moulding,
Wherein, auxiliary material comprises pigment or coloring agent at least, adopts the pigment of solid color or the liquid material that coloring agent mixes solid color, and wherein the mass percentage content of each composition is as follows:
Polyvinyl chloride: 40% ~ 60%;
Citric acid: 31% ~ 59%;
Vinyl acetate: 0.08% ~ 15%;
The two hard acid amides of ethylene: 0.05% ~ 5%;
Auxiliary material: surplus;
And auxiliary material comprises lubricant, heat stabilizer, filler, lubricant is the two hard acid amides of calcium stearate, zinc stearate or ethylene, its shared quality is 0.03% ~ 5% than span, heat stabilizer is organo-tin het stabilizer or calcium zinc stabilizer, its shared quality is 0.014% ~ 0.25% than span, filler is inorganic filler, as calcium carbonate, kaolin, talcum powder or carbon black, and baking can be adopted the tunnel type baking box, the baking temperature span be 120 spend to 160 the degree, the stoving time span is 15 minutes to 30 minutes.
Another kind of eraser manufacturing method, this method is used to produce a kind of rubber of polychrome, comprising:
Adaptation step: the liquid material that polyvinyl chloride, citric acid, vinyl acetate, the two hard acid amides of ethylene and auxiliary material is deployed into multiple color according to preset blending ratio, proportioning and one-tenth component selections thereof can be chosen with reference to a last embodiment, repeat no more herein, auxiliary material comprises pigment or coloring agent at least, mixes the liquid material of at least two kinds of different colours by adopting different pigment or coloring agent;
Forming step: add in the mould successively the liquid material of described different colours respectively, and the first baking-curing liquid material of another kind of color that reinjects behind the liquid material of a kind of color of every adding, and baking-curing, by this circulation forming processes, become the solidfied material of multiple color until final molding.
Implement rubber constituent and the eraser manufacturing method of the invention described above embodiment, mainly comprise and adding in the mould after the two hard acid amides of polyvinyl chloride, citric acid, vinyl acetate, ethylene and auxiliary material be deployed into liquid material according to preset blending ratio, and baking-curing moulding, become rubber after the final correction outward appearance, can produce the erasing rubber of various shapes, bright in luster and environmental protection, not only can in learning life, increase entertaining, also help people's health; In addition, wherein polyvinyl chloride is a major ingredient, citric acid is for guaranteeing the material of rubber certain degree of hardness, vinyl acetate is for guaranteeing the material of the certain toughness of rubber, and the two hard acid amides of ethylene can reach the effect of lubricated and dispersion to improve release property, and lubricant has lubricated and thermal stability result, can prevent variable color, heat stabilizer has and prevents that material from crossing the effect of heat ageing, and when making transparent rubber, filler can; In addition, the baking temperature span is 120 to spend to 160 degree, and this temperature belongs to low temperature for existing serviceability temperature of dripping the glue technology, adopt this kind temperature non-degradable to guarantee polyvinyl chloride; In addition, the stoving time span is 15 minutes to 30 minutes, can guarantee that polyvinyl chloride fills part plasticizing, and this time prolonged with respect to the existing time of dripping the glue technology, drips about several seconds of glue time spent to somewhat, can be as the production rubber time spent so long.
The above is the specific embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
