Abstract
The invention relates to a defoaming agent and a production process, and the defoaming agent is composed of components with the following parts by weight: 60 parts of dimethyl silicone oil, 15 parts of glyceryl polyether 3050, 15 parts of liquid paraffin and 10 parts of water. The production process comprises the following steps: 10 parts by weight of water is added in a reactor; 60 parts by weight of dimethyl silicone oil is slowly added in the reactor to be stirred at the normal temperature, thus forming emulsion-like solution; 15 parts by weight of glyceryl polyether 3050 is added to be continuously stirred at the normal temperature till the glyceryl polyether 3050 is fully dissolved in the emulsion-like solution; 15 parts by weight of liquid paraffin is further added to be continuously stirred at the normal temperature till the liquid paraffin is fully dissolved in the emulsion-like solution; the low-speed stirring is carried out for 30 minutes, the solution is kept at 18 DEG C to 22 DEG C, and the defoaming agent is prepared by carrying out the reactor for 24 hours. The defoaming agent and the production process have the advantages that: the production process has no waste gas, no waste water and no noise to be discharged to the outside; the product is fully dissolved in the water and non-toxic, thus not producing secondary environmental pollution, the product is used in a big water region, the defoaming speed is fast, the using amount is small and the cost is low.
Description
Technical field
The invention belongs to chemical field, relate in particular to a kind of defoamer and manufacture craft thereof.
Background technology
Existing defoamer has waste gas in process of production, waste water effluxes and noise problem, and the speed of froth breaking is slower in the waters that existing defoamer is big in the water yield, flow velocity is fast, use amount is big, the floating oil phenomenon is arranged, the cost height also contains APEO (NPE), OPEO (OPEO), DPEO (dodecyl APEO), DNPEO (binonylphenol polyvinyl chloride ether), directly the health of harm humans, fish, algae produces secondary pollution to environment.
Summary of the invention
The purpose of this invention is to provide a kind of defoamer and manufacture craft thereof, to overcome above shortcomings in the existing defoamer production process.
Its component by following weight portion of defoamer of the present invention is made: dimethicone: 60; Glycerin polyether 3050:15; Atoleine: 15, water: 10.
Defoamer manufacture craft of the present invention may further comprise the steps:
The water of 10 weight portions is added in the reactor;
Dimethicone with 60 weight portions adds in the above-mentioned reactor lentamente, starts stirring, and about 50 rev/mins of rotating speeds stir under the normal temperature, forms emulsion-like solution;
The glycerin polyether 3050 that adds 15 weight portions, normal temperature continue down to stir, and about 50 rev/mins of rotating speeds are until glycerin polyether 3050 is dissolved in the emulsion-like solution entirely;
The atoleine that adds 15 weight portions again, normal temperature continue down to stir, and about 50 rev/mins of rotating speeds are until atoleine is dissolved in the emulsion-like solution entirely;
Stirred at a slow speed 30 minutes, about 50 commentaries on classics/per minutes keep 18 ℃-22 ℃, react and promptly make defoamer of the present invention in 24 hours.
Dimethicone used in the present invention is nontoxic, dissolve in water, froth breaking entirely, and it is strong to press down the bubble ability; Employed glycerin polyether is 3050 nontoxic, dissolve in water entirely, penetration is strong, diffusion is fast; Employed atoleine is nontoxic, dissolve in water entirely, proportion, is kept afloat as the carrier of defoamer in water less than water, the effect of omnibearing performance froth breaking.
Beneficial effect of the present invention is: do not have waste gas, no waste water, no dry sound in the production process of the present invention and efflux; Product is water-soluble entirely, nontoxic, and environment is not produced secondary pollution, not the health of harm humans, fish, algae; Do not contain APEO (NPE), OPEO (OPEO), DPEO (dodecyl APEO), DNPEO (binonylphenol APEO), use in big waters, the speed of froth breaking is fast, and use amount is little, cost is low.
The specific embodiment
The described defoamer of present embodiment is made by following component: dimethicone 60kg; Glycerin polyether 305015kg; Atoleine 15kg, water 10kg.
The described defoamer manufacture craft of present embodiment may further comprise the steps:
10kg water is added in the reactor; Lentamente the 60kg dimethicone is added in the above-mentioned reactor, start stirring, about 50 rev/mins of rotating speeds stir under the normal temperature, form emulsion-like solution; Add 15kg glycerin polyether 3050, normal temperature continues to stir down, and about 50 rev/mins of rotating speeds are until glycerin polyether 3050 is dissolved in the emulsion-like solution entirely; Add the 15kg atoleine again, normal temperature continues down to stir, and about 50 rev/mins of rotating speeds are until atoleine is dissolved in the emulsion-like solution entirely; Stirred at a slow speed 30 minutes, about 50 commentaries on classics/per minutes keep 18 ℃-22 ℃, react and promptly make defoamer of the present invention in 24 hours.
Claims (2)
1, a kind of defoamer is characterized in that, its component by following weight portion is made: dimethicone: 60; Glycerin polyether 3050:15; Atoleine: 15, water: 10.
