Abstract
The invention discloses a sticking enhancing water-loss reducer which comprises sodium carboxymethylstarch, cross-linked polysaccharides acetic ester, konjac glucomannan and light calcium carbonate, the interior wall coating prepared from the agent has high bonding strength.
Description
Technical field
The present invention relates to a kind of building adhesive, especially relate to a kind of gypsum building plaster the material usefulness tackify water conservation tackiness agent.
Background technology
Inner wall of building is decorated the used material (being commonly called as putty) of plastering, and generally is made up of filler, tackiness agent and auxiliary agent.Tackiness agent is at present widely used to be 107 glue, the glue that 801 glue and polyvinyl alcohol boil, and these glue generally contain harmful substance formaldehyde, and product is liquid.Very inconvenience of packing, transportation had irritating smell in using,, dry linting poor, not water-fast, easy to crack with the product bonding strength of its production.Especially now a large amount of little factories cause the formaldehyde content severe overweight not according to processing requirement production, and effective constituent does not reach the content of regulation, causes quality product low, easily causes construction quality problem, and people's health is caused detrimentally affect.
The also useful full-bodied ether of cellulose series products of tackiness agent of plastering and expecting, as carboxymethyl cellulose, Natvosol, Vltra tears, methylcellulose gum etc., these product ubiquity water retention property do not reach the requirement of the material of plastering, and workability is poor, smear effort, bonding strength is poor, easy to crack, dry linting.And use the price height, the sale price of these products is ten thousand yuan/ton of 2-8.
The tackiness agent of material of plastering has also that to adopt W-Gum to add caustic soda synthetic.Product is strong basicity, with the product of its production alkalescence PH 〉=12, emulsion paint used produce harm.The workmen is in the blade coating process, easily burn hand, the polishing nose of the time choking, the putty intensity difference of production, not water-fast, easy peeling.
The neutral dry binder is also arranged on the market, is high-viscosity building paint glue powder in the CN1225934A patent as publication number, but price is more than 30,000 yuan/ton, and high price is expensive, and the user is few.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, a kind of bonding strength height is provided, water retention property is good, formaldehydeless, nonpoisonous and tasteless, environmental protection, pH value are neutral, use the low instant tackify water-holding agent of powdered of price, smear the end material with the interior wall of this agent and gypsum and auxiliary agent production, have the bonding strength height, water-fast, have good workability, advantage such as environmental protection.To replace 107 or 801 glue and the expensive ether of cellulose series products that existing market is used.This agent prescription is reasonable, and is easy to use, and contained each matter interaction in the prescription plays good tackify water retention.
To achieve these goals, the present invention is by the following technical solutions:
The plaster tackify water-holding agent of material usefulness of a kind of gypsum building, this agent is made up of crawl sweet glycan, light calcium carbonate of sodium starch glycolate, cross-linked polysaccharides acetic ester, konjaku.
Described tackify water-holding agent is pressed column weight amount per-cent and formed: its scheme is: sodium starch glycolate 10-25%, cross-linked polysaccharides acetic ester 30-55%, konjaku crawl sweet glycan 0.5-4%, light calcium carbonate 20-45%.
The preferred version of tackify water-holding agent is: sodium starch glycolate 20-25%, cross-linked polysaccharides acetic ester 30-45%, konjaku crawl sweet glycan 1-2%, light calcium carbonate 21-45%.
The better scheme of tackify water-holding agent is: sodium starch glycolate 11-14%, cross-linked polysaccharides acetic ester 40-50%, konjaku crawl sweet glycan 3-4%, light calcium carbonate 30-45%.
The preferred plan of tackify water-holding agent is: sodium starch glycolate 15-20%, cross-linked polysaccharides acetic ester 45-55%, konjaku crawl sweet glycan 2-3%, light calcium carbonate 25-30%.
Described tackify water-holding agent preparation process is as follows:
1. each material in the above-mentioned tackify water-holding agent is taken by weighing by weight percent separately.
2. earlier drop into sodium starch glycolate, cross-linked polysaccharides acetic ester in the taper mixing kettle, drop into again konjaku crawl sweet glycan, drop into light calcium carbonate at last.
3. start the stirring of taper mixing kettle and mixed in 15-30 minute, promptly get the tackify water-holding agent.
Adopt technique scheme, beneficial technical effects of the present invention is: sodium starch glycolate is a kind of anionic macromolecular material, and its external form is for white or have yellowish pressed powder, and the easy moisture absorption, odorless can be directly water-soluble.Its aqueous solution has good viscosity, stability, protective colloid and film-forming properties, is difficult for corrupt mildew, and is stable under alkalescence and solutions of weak acidity, makes suspension agent, stablizer, membrane-forming agent in water-based paint, has effects such as emulsification, thickening, anti-deposition.The cross-linked polysaccharides acetic ester is introduced ester group in polysaccharose substance, thereby stops or reduced the straight-chain molecule hydrogen bond association, and product stability in solution is increased, and retrogradation weakens, and transparency is good, the film soft and bright.The konjaku sweet glycan molecular weight of crawling is big, the 200-300 of its inflatable own wt that absorbs water doubly, crawl sweet glycan swelling capacity and improve the chemical polymerization thing that the liquid viscosity ability surpasses known any natural polymer and synthetic of konjaku has good thickening, lubricated, tackifying.Light calcium carbonate plays dispersion, antiseized effect.More than each materials cooperation effect have stronger tackify, water conservation, oilness.Can satisfy gypsum building plaster the required water-retentivity of material, well smearing property, increase the performance of bonding strength.This tackify water-holding agent is synthetic by natural product, nonpoisonous and tasteless, environmental protection.
