Description
Technical field
The present invention relates to a kind of putty powder binding agent, specifically a kind of plant modified polymer putty glue paste and preparation method thereof.
Background technology
Putty is a kind of material of construction of large usage quantity in building decoration, can, by smooth wall-surface patching its finishing material that reaches smooth fine and smooth effect that makes, mainly be formed by filler (calcium carbonate), binding agent (glue or rubber powder), solvent (water or other solvents) and additive (auxiliary agent).The putty material that at present finishing uses mainly contains on-the-spot mixed matching putty powder (as polyvinyl alcohol urea-formaldehyde glue liquid+Paris white+ripe rubber powder etc.), finished product water and type putty powder (putty powder+water) etc.; Current on-the-spot mixed matching putty powder is all generally that polyvinyl alcohol, formaldehyde, urea etc. are brewed into glue (having producer to manufacture specially glue production marketing) through high temperature, become the construction of paste putty by material field mix such as glue and calcium carbonate again, putty defect is that cost is high, complex procedures, formaldehyde pollution etc.Finished product water and type putty powder mainly adopt the rubber powder such as tapioca (flour) or W-Gum as binding agent, with Paris white carry out factory's pre-mixing filling become production marketing, the scene construction that need add water.
Indispensable part when glue paste is putty mixture, intensity, application property and weather resistance for putty powder play conclusive effect, the quality of glue paste has determined the quality of putty powder, existing glue paste is main liquid and pulverous two kinds, what pulverous glue paste was conventional is tapioca (flour) or W-Gum, although tapioca (flour) cohesive action is large, if but addition greatly, affect the workability of putty powder, be difficult for criticizing and scrape, if addition is little, cohesive strength (sticking power) is low does not reach requirement, is unfavorable for composite; W-Gum is little to cohesive strength effect, and putty powder or the work-ing life of manufacturing with these two kinds of rubber powders are short, easily hollowing shedding, otherwise workability is poor etc.; The general effect of rubber powder is better relatively in the use for liquid glue paste, and easy to use, but the manufacture craft of existing liquid viscose glue trouble, cost is high, complex procedures, and formaldehyde pollution, environmental-protecting performance is low.
Summary of the invention
The object of the invention is to the defect for prior art, provide a kind of bond effect good, technique is simple, with low cost, plant modified polymer putty glue paste and preparation method that environmental-protecting performance is high.
Technical scheme provided by the invention: described a kind of plant modified polymer putty glue paste, is characterized in that the ratio of weight and number of each moiety in described caulk compound is:
Wherein: described mixed plant raw material is to be mixed according to the ratio of mass ratio 1:2～3 by konjaku and potato after pulverizing;
The polyvinyl alcohol water solution of described concentration 2% is under the condition of 95-98 ℃, to boil the transparent colloidal liquid that after 1-2 hour, naturally cooling forms after being mixed according to the ratio of mass ratio 2:98 by polyvinyl alcohol and deionized water;
Described linking agent is Monochloro Acetic Acid or trichoroacetic acid(TCA).
Described sanitas is the food preservatives such as Sodium Benzoate, Kathon CG (molecular formula: C4H4ClNOS+C4H5NOS, chloro-2 isothiazoline-3, methyl-4 ketone and the MITs of chemical name: 5-).
Another kind of technical scheme provided by the invention is: a kind of method of preparing above-mentioned plant modified polymer putty glue paste, and concrete steps are as follows:
(1) take konjaku and potato as major ingredient, first cleaned respectively after impurity elimination, peeling, take a certain amount of konjaku and potato according to mass ratio 1:2～3, and be pulverized and mixed the mixed plant raw material that forms konjaku and potato;
(2) take the mixed plant raw material of pulverizing formation in step (1), then add successively linking agent, soda ash and deionized water, at 1～2 normal atmosphere, 100～130 ℃, react and form mixed glue solution in 20～40 minutes, wherein in the mixed plant raw material of every 100 weight parts, add 0.1～0.3 part of linking agent, 0.1～0.3 part of soda ash and 180～220 parts of deionized waters;
(3) after being mixed according to the ratio of mass ratio 2:98, polyvinyl alcohol and deionized water under the condition of 95-98 ℃, boil the transparent colloidal liquid that after 1-2 hour, naturally cooling forms, i.e. the polyvinyl alcohol water solution of concentration 2%;
(4) in step (2), in the mixed glue solution of preparation, add successively mixed stirring of polyvinyl alcohol water solution, food grade preservative and carboxymethyl cellulose of the concentration 2% of preparation in step (3) to form plant modified polymer putty glue paste, wherein in the plant material of every 100 weight parts, add polyvinyl alcohol water solution, the food grade preservative of 0.11-0.21 weight part and the carboxymethyl cellulose of 1-3 weight part of the concentration 2% of 10-25 weight part.
Linking agent described in step (2) is Monochloro Acetic Acid or trichoroacetic acid(TCA).
Beneficial effect of the present invention:
(1) the employing konjaku in the present invention and potato are as plant material, vegetable polysaccharides and the starch content of konjaku and potato are higher, the mixed solution obtaining after modification, polymerization contains more water miscible group, make it strengthen stability, reduced gelatinization point, improved viscosity, and plant material is all natural component, nontoxic, formaldehydeless pollution, harmless, good environmental protection;
(2) to add concentration be 2% polyvinyl alcohol water solution in the present invention, concentration is that 2% polyvinyl alcohol water solution is through boiling and form for a long time by polyethylene alcohol and water, itself just has certain viscose glue, join in glue prepared by plant material, increase the stickiness of glue, played good adhesive effect, improved the stickiness of putty caking agent, make putty bonding strength good, avoid the quality problems such as putty occurs ftractureing, peels off in construction, dry linting; And the polyvinyl alcohol amount adding is little, its environmental-protecting performance is high;
(3) the present invention has also added carboxymethyl cellulose, and glue water-retentivity, oilness are further improved;
(4) the present invention has also added sanitas, can play preservative activity to whole product, increases its preservation time, and sanitas selects the sanitas of food grade, makes whole product use safer, environmental protection.
The present invention is used in the putty powder of building materials field, can increase the workability of putty, be easy to criticize and scrape, less addition can reach good bond effect, be easy to putty powder in other additive compound, the putty good stability after batch scraping, be difficult for hollowing shedding, long service life, and take natural phant as raw material, harmless.
