Abstract
An antimildew starch composition used in paint, adhesive and moulding sand contains starch, sulfite and ascorbic acid, and features not mildewing and not saccharifying so as to expand the use scope and effect of starch.
Description
The present invention relates to starch composites, refer to especially a kind ofly make starch have anti-mildew to become the anti-mildew starch composition of not saccharification character by adding xitix and sulphite.
Existing untreated common starch is easy to go mouldy under the natural condition of colloidal state, saccharification; in building coating, use; or at foundry work moulding sand; when in carton is produced, using this common starch; regular meeting is because starch goes mouldy over time, saccharification; and making application component rotten, this defective is restricted the use of common starch.
The objective of the invention is to overcome the problem that existing common starch exists, provide a kind of and can anti-mildew become, the starch composites of not saccharification.
Starch composites of the present invention comprises starch (or treated starch), sulphite and xitix.Wherein, starch is untreated common starch (or alphalysed starch), and sulphite can be S-WAT, potassium sulfite or sodium bisulfite or sodium acrylate or vinylformic acid hydrogen sodium.
The proportioning of each component (weight part is represented) is in the starch composites of the present invention:
Starch 800---1000 parts
Sulphite 15---100 parts
Xitix 1---100 parts
The production method of starch composites of the present invention is: add the sulphite and the xitix of said ratio in common starch (or alphalysed starch), get final product with the stirrer stirring and evenly mixing down in normal temperature and pressure.
Xitix of the present invention is a strong reductant, and it can capture the lip-deep oxygen of starch, make starch not with oxygen generation oxidizing reaction; Sulphite is the inhibitor of enzyme, but the reaction of inhibitory enzyme Catalytic Oxygen and starch is again the protective material of xitix simultaneously.
Starch composites of the present invention in use, anti-mildew becomes, not saccharification, it is embodied in:
1. this starch composites is put into building coating 821 putty powder, to replace original used PV1788.(the 821st, by talcum powder, terra alba, Mierocrystalline cellulose, anti-saccharification alphalysed starch 70: 28: 1 by weight: 1 proportioning constituted) stirs this mixture with stirrer in per ton 821, adds water to pasty state, rinses wall with it, detects after 1 year not have and goes mouldy.
With starch composites by 1 kilogram of alphalysed starch composition: 15 kg water mixed become pasty state, are used for the bonding of carton, and bonding firmly detected in back 1 year, not having goes mouldy take place and cohesive force constant.
3. in foundry work moulding sand, get the sand double centner, sand, oven dry are processed in 5 kilograms of thorough mixing of starch composites, stirring, under the natural condition, deposit half a year, not saccharification, and nothing is gone mouldy.
The present invention is described in detail below in conjunction with embodiment.
Embodiment 2
Take by weighing 1000 kilograms of starch, the sodium bisulfite double centner, the xitix double centner, production method is as embodiment 1.
Embodiment 3
Take by weighing 800 kilograms of starch, 15 kilograms of potassium sulfites, 1 kilogram in xitix, production method with embodiment 1.
Claims (3)
1. a starch composites comprises starch, sulphite and xitix.
2. the described starch composites of claim 1, the proportioning of wherein said each component (weight part is represented) is:
Starch 800---1000 parts
Sulphite 15---100 parts
Xitix 1---100 parts
3. the described starch composites of claim 1, wherein said sulphite are selected from a kind of in S-WAT, sodium bisulfite and the potassium sulfite.
