10~15 parts by weight of work oil, 3~5 parts by weight of calcium stearate and nano essence microcapsules, the use of the nano essence microcapsules
Amount is the 20~30% of erasing rubber total weight.
Preferably, the raw material composition of the environment-protecting and non-poisonous fragrant erasing rubber are as follows:
25 parts by weight of thermoplastic styrene butadiene rubber, 5 parts by weight of polystyrene, 50 parts by weight of calcium carbonate, 15 parts by weight of processing oil,
5 parts by weight of calcium stearate and nano essence microcapsules, the dosage of the nano essence microcapsules are erasing rubber total weight
25%.
In the present invention,
The processing oil is that one or more of tributyl citrate, epoxidized soybean oil, polyol ester arbitrarily compare
The mixture of example；
The essence of the nano essence microcapsules is plant extract essence, such as: cream jasmin france, lemon extract, minty note
Essence, lavender oil, orange flavor.
Environment-protecting and non-poisonous fragrant erasing rubber of the present invention the preparation method comprises the following steps:
According to composition of raw materials, by thermoplastic styrene butadiene rubber refining glue on a mill, calcium carbonate and hard is added in mixing process
Resin acid calcium, 5~10min of mill, roller temperature are 160~180 DEG C, and by the glue refined be chopped into graininess (partial size 3~
5mm), butadiene-styrene rubber particle is obtained, gained butadiene-styrene rubber particle is mixed with polystyrene, processing oil, nano essence microcapsules
Uniformly, 5~10min of mixing discharges at 160~180 DEG C in mixer, and resulting material is warming up to 150~180 DEG C of moldings
Molding is cooled to room temperature (20~30 DEG C) to get the environment-protecting and non-poisonous fragrant erasing rubber.
Compared with prior art, the beneficial effects of the present invention are:
(1) pure natural plant essence is used, it is not only nontoxic, but also there is intense strain of releiving, pressure relief, town
The effect of Jing'an mind.
(2) capsule of nano is made in essence, has completely cut off the contact of essence and the external world, avoid the stimulation by photo-thermal etc. and
Volatilization failure, maintains the flavor of essence.
