Abstract
The invention discloses a kind of Heveatexes, silica gel product.Including additive, the additive is modified starch.The modified starch is added in the compounding process that Heveatex, silica gel product manufacture production process.The modified starch uses in Heveatex, silica gel shaped article as anti-adhesion agent or optical brightener or slip agent or interleaving agent.What the modified starch was obtained by: starch oxidation gelatinization being handled, silane coupling agent is added and carries out graft reaction, modified starch is prepared.Heveatex of the invention, silica gel product use as anti-adhesion agent or optical brightener or slip agent or interleaving agent in Heveatex, silica gel shaped article using modified starch as additive, avoid harm of the shaped article to human body.
Description
Technical field
The present invention relates to chemical technology field more particularly to a kind of Heveatexes, silica gel product.
Background technique
Heveatex is a kind of natural polymer lotion by Brazilian para ruber biosynthesis.It is believed that natural
The nonrubber materials such as glue protein of milk and lipides form protective film around rubber particles, keep rubber particles negatively charged
Lotus, to form stable colloidal dispersion.Under normal circumstances, the fresh Heveatex acquired from rubber tree passes through centrifugal concentrating
Afterwards, mechanical stability is between 100-200 seconds；It can be more than " 8289 concentrated natural latex of GB/T after natural storage 2 months
Ammonia save centrifugation or livering latex specification " as defined in minimum limit value 650 seconds, can reach more than 900 seconds.
Silica gel, also known as silicic acid gel are a kind of high activity adsorbent materials, belong to amorphous substance.Silica gel main component is two
Silica, chemical property are stablized, do not burn.Chemical formula xSiO2·yH2O.Transparent or milky granular solids.With open more
Pore structure, strong adsorption can adsorb many kinds of substance.Dilute sulfuric acid (or hydrochloric acid) is added in the aqueous solution of waterglass and stands, just
The solid state as aqueous silicic acid gel.It is removed with washing and is dissolved in electrolyte Na therein+And SO42-( Cl-) ion, it does
Silica gel can be obtained after dry.Such as absorb moisture, part silicone gel hygroscopic capacity about 40% or even 300%.For gas dry, gas is inhaled
It receives, dehydrate liquids, chromatographic analysis etc. is also used as catalyst.Cobalt chloride is such as added, it is blue when dry, it takes on a red color after water suction.It can
Regenerate Reusability.
Many of actual life Heveatex, silica gel shaped article such as sheath, contraceptive cap, finger-stall, gloves, are led
Urinary catheter, urinal, balloon, instrument, utensil, toy etc..Above-mentioned Heveatex, silica gel are during formed product, due to product
Can needs, need to add some additives in process of production, the processability of Lai Zengjia product, what most domestic used
It is mineral substance powder；Such as talcum powder, white carbon black.Substance of this kind has certain harm to human body, and developed regions, American-European countries are
Disabling.
Summary of the invention
Object of the present invention is to solve the above problems, a kind of Heveatex, silica gel product are invented, avoids shaped article to human body
Harm.
To achieve the goals above, the technical scheme is that
A kind of Heveatex, silica gel product, including additive, the additive are modified starch.
As further improvement to above-mentioned technical proposal, the modified starch is in Heveatex, silica gel product manufacture life
It is added in the compounding process of production process.
As further improvement to above-mentioned technical proposal, the modified starch is in Heveatex, silica gel shaped article
It is used as anti-adhesion agent or optical brightener or slip agent or interleaving agent.
As further improvement to above-mentioned technical proposal, what the modified starch was obtained by: starch oxidation is pasted
Change processing is added silane coupling agent and carries out graft reaction, modified starch is prepared.
Compared with prior art, the advantages and positive effects of the present invention are:
Heveatex of the invention, silica gel product are made in Heveatex, silica gel shaped article using modified starch as additive
It is used for anti-adhesion agent or optical brightener or slip agent or interleaving agent, avoids harm of the shaped article to human body.
