Wallpaper stickup glutinous rice glue of constructing and preparation method thereof converted in a kind of easy tune
Technical field
The invention belongs to wallpaper adhesive industry, particularly wallpaper stickup glutinous rice glue of constructing and preparation method thereof converted in a kind of easy tune.
Background technology
Along with continuous " intensification " of several years ago real estate market, the domestic environment potential safety hazard caused by house ornamentation attracts people's attention.From the data that can inquire about, it is pollute the third phase indicated that modern is entering with " room air pollution ".The toxic substance discharged in house decoration material has formaldehyde, toluene diisocyanate, organic volatile, asbestos, ammonia, radon etc., and wherein nearly kind more than 20 has been confirmed to be carcinogens and mutagen.New clothes are repaiied house indoor atmospheric pollution and are very likely had a strong impact on healthy even carcinogenic as can be seen here, and therefore selection material is comparatively crucial, wherein use wallpaper to be that the current constructional ornamental material market share takies larger house ornamentation means.
Through development nearly ten years, wallpaper progressively develops into weaving, nonwoven, environmental protection, ecology, green product from single product, put up wallpaper, wall cloth auxiliary material thereupon, tackiness agent, also towards function future developments such as health, ecology, environmental protection, substitutes the tackiness agent that tradition uses high-content white glue with vinyl completely.
Relative environmental protection on domestic market and to use more be starch conversion tackiness agent, but there is many deficiencies or problem: because this tackiness agent cools 30 DEG C by after certain starch and the hot gelatinization of treated starch, after add 30% low-solid content white glue with vinyl and stir, produce paste white glue with vinyl.Its production cost is high, and use when pasting wallpaper, wallpaper not easily moves, cannot parquets, to flower.Construction is overflow glue not easy cleaning, coheres and unevenly easily occurs bubble, bulge phenomenon.
Because product interpolation thickening white glue with vinyl is Chemicals, inadequate environmental protection, indoor extended residual chemical industry monomer smell, and do not add the viscosity that thickening white glue with vinyl can not ensure product.Especially in the high wallpaper such as high-grade pure paper, gold foil paper of processing requirement, wall cloth application, often cause because bonding effect is undesirable repeating construction, material resources waste, sharply add and rise cost, be difficult to meet user demand completely, restriction wallpaper industry is advanced and development.
Summary of the invention
The present invention is directed to the defect of prior art, provide a kind of easily tune to convert, coating good leveling property, final product is not containing formaldehyde, and nontoxic, the wallpaper stickup glutinous rice glue of constructing converted in the easy tune that high/low temperature stability is good.
The preparation method of the wallpaper stickup glutinous rice glue that the present invention also provides above-mentioned easy tune to convert to construct.
The technical solution adopted for the present invention to solve the technical problems is:
A wallpaper stickup glutinous rice glue of constructing converted in easy tune, and this glutinous rice glue is mainly made up of the raw material of following weight part:

As preferably, wetting agent is any one or combination of Macrogol 200, poly(oxyethylene glycol) 400, propylene glycol, and mould inhibitor is any one or two or more combinations in Sodium dehydroacetate, sodium Diacetate, calcium propionate, tennecetin.
As preferably, sterilant is the combination of in glacial acetic acid, ethanol, M-nitro benzoic acid, potassium sorbate more than at least three kinds.As preferably, sterilant is glacial acetic acid: ethanol: M-nitro benzoic acid: the compound that potassium sorbate mixes with the weight proportion of 5:10:1-2:0-2.
The preparation method of the wallpaper stickup glutinous rice glue of constructing converted in a kind of described easy tune, the method is mainly: according to proportioning by after sticky rice flour, waxy corn starch, W-Gum, wheat starch, yam starch, tapioca (flour) premix, add wetting agent, linking agent and cationic etherifying agent and carry out crosslinked and the process of positively charged ion etherificate, add catalyzer more afterwards and negatively charged ion etherifying agent carries out carboxymethylation process, obtain composite modified starch breast, 40 ~ 120min is reacted, germicidal treatment discharging packing again after adding sterilant, mould inhibitor again.
As preferably, the method is mainly: according to proportioning by sticky rice flour, waxy corn starch, W-Gum, wheat starch, yam starch, after tapioca (flour) premix, add wetting agent, linking agent and cationic etherifying agent carry out crosslinked and the process of positively charged ion etherificate, dispersed with stirring heated up 35 ~ 50 DEG C after 30 minutes, constant temperature 3 hours ~ 5 hours, add catalyzer dispersion stirring 10 ~ 20 minutes afterwards, add negatively charged ion etherifying agent again and carry out carboxymethylation process, react and obtain composite modified starch breast after 40 ~ 60 minutes, add sterilant again, 40 ~ 120min is reacted after mould inhibitor, germicidal treatment discharging packing again.
The present invention a kind ofly adopts the ative starch materials such as natural glutinous rice starch, waxy corn starch, W-Gum, wheat starch, yam starch, tapioca (flour), by carrying out suitable compatibility to the category of ative starch and tret, carry out crosslinked denaturing treatment, positively charged ion etherificate denaturing treatment, the triple complex denaturation process of carboxymethyl etherification denaturing treatment again, effectively improve the shortcomings such as the viscosity stability that single variety raw material in the past exists is low, anti-shearing force is poor, resistance to deterioration, anti-microbe ability difference; Meanwhile, the stickup wallpaper glutinous rice glue of exploitation is made to have suitable initial viscosity, good levelling property and very strong cohesive strength; Meanwhile, by starch after complex denaturation process, there is gelatinization point low, close to normal temperature gelatinization, can energy efficient, reducing discharge, is the environment-friendly type wallpaper glue product of the cleaner production of the sustainable cycle development of environmental protection.
The invention has the beneficial effects as follows: wallpaper prepared by the present invention, wall cloth stickup glutinous rice glue product have easily to adjust to be converted, and improves construction impregnation efficiency; Coating good leveling property, is beneficial to the parquets opposite joint of wallpaper wall paper construction; Final product is not containing formaldehyde, nontoxic; Product high/low temperature stability is good, applied widelyly can meet different geographical, the wallpaper of Different climate, wall cloth construction usage require it is promote that industry is healthy, benign development, the good product of benefiting the nation and the people.
