Abstract
The invention relates to the technical field of production of school supplies, in particular to a durable excellent-elasticity eraser, made from 15-25 parts of PVC (polyvinyl chloride) resin, 5-8 parts of butadiene rubber, 3-5 parts of calcium stearate, 3-5 parts of a foaming agent, 2-4 parts of a thickening agent, 6-8 parts of original plant gum, 5-7 parts of a viscosity regulator, 6-8 parts of titanium dioxide, and 5-7 parts of silicon powder. The durable excellent-elasticity eraser has the advantages that the technical process is simple, the ratio of materials is reasonable, high-elasticity gum added into the main materials for stirring is the plant gum which is nontoxic, the use of the butadiene rubber helps increase the hardness, using is not affected, wear resisting is achieved, the service life is prolonged, the application effect is significant, and the eraser is convenient to popularize and use.
Description
Technical field
The present invention relates to study article preparing technical field, be specifically related to a kind of durable in use and eraser that elasticity is superior and preparation method thereof.
Background technology
Eraser, it is many sketches drawing, one of stationery of kindergarten and pupil's indispensability, it is mainly used for wiping mistake lines and wrong person's handwriting, the main component of eraser is plastics, progress greatly that row is prepared from by adding various industrial chemicals and aromatiques, eraser in use, because frequency of utilization is high, therefore consume also larger, traditional eraser is in use due to its formula and the defect of preparation technology, and quickly, and elasticity is also relatively poor in loss, careless slightly, just there will be fracture, impact uses, and use cost also improves relatively.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of formula rationally, and use cost is low, not easy fracture durable in use and eraser that elasticity is superior and preparation method thereof.
Technical problem to be solved by this invention realizes by the following technical solutions:
The eraser that durable in use and elasticity is superior, is characterized in that: be made up of following raw material:
Polyvinyl chloride resin 15-25 part, cis-1,4-polybutadiene rubber 5-8 part, calcium stearate 3-5 part, whipping agent 3-5 part, thickening material 2-4 part, plant virgin rubber 6-8 part, viscosity-controlling agent 5-7 part, titanium dioxide 6-8 part, silica flour 5-7 part.
The preferred ingredient of each raw material is: polyvinyl chloride resin 20 parts, cis-1,4-polybutadiene rubber 6 parts, calcium stearate 4 parts, whipping agent 4 parts, thickening material 3 parts, plant virgin rubber 7 parts, viscosity-controlling agent 6 parts, titanium dioxide 7 parts, silica flour 6 parts.
Described viscosity-controlling agent is silicone oil; Described thickening material is white carbon black; Described whipping agent is water glass.
Described plant virgin rubber is one or any several in amylan, dextrin glue, bean gum, Sudan Gum-arabic, gum rosin, carboxymethyl cellulose gum, xylogen glue.
Another object of the present invention is to provide a kind ofly prepares the durable in use and method of the eraser that elasticity is superior of the present invention, it is characterized in that, comprises the following steps:
1) polyvinyl chloride resin in raw material and cis-1,4-polybutadiene rubber are put into melting furnace heat, until polyvinyl chloride resin and cis-1,4-polybutadiene rubber are molten into liquid state, then the plant virgin rubber in raw material are added wherein, be uniformly mixed;
2) pre-mixing is carried out after the calcium stearate in raw material, titanium dioxide and silica flour being ground, for subsequent use;
3) raw material in step 1,2 is mixed again, and after heated and stirred directly all mixes, add the whipping agent in raw material, viscosity-controlling agent and whipping agent successively, after high-speed stirring 23-30min, discharging after adopting corresponding mould to be prepared, discharging naturally cooling is shaping, can obtain.
The invention has the beneficial effects as follows: present invention process flow process is succinct, reasonable raw material proportioning, adds and adopt the carrying out of high-elastic glue to mix use, and high-elastic glue is vegetable jelly in main raw material, itself is nontoxic, adopt the adapted of cis-1,4-polybutadiene rubber simultaneously, add hardness, not only can not affect use, wear-resisting effect can also be played, effectively raise work-ing life, result of use is obvious, is convenient to promote and use.
