Abstract
The present invention relates to dispersant agent with viscosity breaking and stabilization functions to powder spraying slurry of washing powder. The present invention is characterized in that the dispersant agent is a graft polymer, the backbone chain is poly-carbonate, the weight-average molecular weight is 10000 to 100000, and the polymerization monomer is organic acid containing an unsaturated double bond, such as one or more of crylic acid, maleic acid, itaconic acid, alkenyl sulphoacid, etc.; the side chain redical is a large molecule monomer with the weight average molecular weight of 100 to 2000 and containing an unsaturated double bond, the large molecule monomer can be allyl sulfide polyether, polyoxyethylene glycol mono-acrylate, and allyl alcohol polyethenoxy ether, etc.; the side chain redical occupies 10 to 80 percent of the weight of a polymer. The more preferable is 20 to 50 percent. The present invention not only has the repulsion of electric charge, but also the steric hindrance effect produced by the side chain redical has good dispersal effect to large granule insoluble substance, the coefficient of viscosity of an edifice can be effectively decreased, and the stability of the edifice is increased. The present invention is applied to the dispersal of multiple aqueous high concentration suspension systems such as the powder spraying slurry of the washing powder and paints, thereby improving the stability of the product.
Description
Technical field
The present invention relates to a kind of water-based branched chain polymer dispersion agent, thing does not relate to a kind of graftomer, is applicable to that the washing powder slip reduces viscosity, improves stability and dispersing of pigments agent.
Background technology
The dispersion agent of powder spraying slurry of washing powder viscosity reduction use at present, it mainly is polycarboxylate, but,, and be suitable in the less system of suspended particle at some lower concentrations because such dispersion agent only reaches dissemination by charge repulsion, owing in the aqueous suspension system of high density a large amount of insoluble particles is arranged, and some particle possibility particle diameter is bigger, and common dispersion agent is difficult to it is uniformly dispersed, and causes insolubles cohesion to occur, even the sedimentation layering appears, have a strong impact on its use properties.
Summary of the invention
Purpose of the present invention is the problems referred to above at the washing powder slip dispersion agent existence of present use, and a kind of dispersion agent and pigment dispersing agent to washing powder slip landing viscosity reduction and stabilization function is provided, and the chemical name of its dispersion agent is:
The polycarboxylate multipolymer of band hydrophilic macromolecule side chain
Dispersion agent to washing powder slip landing viscosity reduction and stabilization function of the present invention, be a kind of graftomer: main chain is a polycarboxylate, its weight-average molecular weight is 10000-100000, its polymerization single polymerization monomer be the organic acid that contains unsaturated double-bond as, vinylformic acid, toxilic acid, furoate clothing, one or more of olefin sulfonic acid etc.
Side chain is that weight-average molecular weight is the macromonomer that contains unsaturated double-bond of 100-2000, and this macromonomer can be allyl polyether, polyoxyethylene glycol mono acrylic ester, allyl alcohol polyethenoxy ether etc.
Side chain accounts for the 10-80% of whole polymer weight.More preferably 20-50%.
Its molecular formula is:
Experimental technique:
At first in the 1000ml flask, add 150g distilled water, heat with oil bath, with vinylformic acid 100g, methallylsulfonic acid sodium 5g, 2 mercapto ethanol 2g, allyl alcohol polyethenoxy ether (molecular weight 1000) 80g distilled water 50g is mixed with mixing solutions, get hydrogen peroxide (35%) 5 gram, be dissolved in the 100g distilled water, treat that the distilled water in the flask is heated to 95 ℃, beginning drips two kinds of solution simultaneously.Keep temperature of reaction between 95-98 ℃.About 1 hour, dropwise.Dropwise the back 95 ℃ of insulation reaction two hours.Being cooled to 60 ℃ then, to be neutralized to the pH value with 30%NaOH solution be 8-9.Obtain the polymers soln about 35%.
Dispersion agent to washing powder slip landing viscosity reduction and stabilization function of the present invention owing to be that a kind of main chain is the graftomer of polycarboxylate, grafting a large amount of polymer side chain and produce special pectination.The sterically hindered effect that its side chain produced because its special pectination not only has the charge repulsion of common dispersion agent can effectively reduce system viscosity to disperseing oarse-grained insolubles dispersion effect good, and the increase system is stable.The present invention is applicable to the dispersion of numerous water-based high-concentration suspension systems such as powder spraying slurry of washing powder, pigment, reduces product viscosity, improves product stability.
