Abstract
The invention belongs to the processing field of auxiliary chemicals, and specifically relates to a high temperature resistant defoaming agent and a preparation method thereof. The high temperature resistant defoaming agent comprises the following materials: 50 parts of p-xylene, 50 parts of diphenylmethane, 5 parts of one or more composition selected from phenyl silicone oil, methyl phenyl silicone oil and methyl ethyoxyl silicone oil, 1 part of polysorbate and 2 parts of one or two compositions of polypropylene and polystyrene. The prepared defoaming agent can resist high temperature, is stable in chemical properties, is non-toxic, has no pollution to environment and is convenient for transportation. The defoaming agent is widely in application, can be used in the fields of chemistry, printing and dyeing.
Description
Technical field
The invention belongs to auxiliary chemicals manufacture field, be specifically related to a kind of high temperature resistant defoamer and preparation method thereof.
Background technology
In industrial production, often there will be foam, as deal with improperly, foam can affect production efficiency and product quality.Mostly adopt at present the chemical method of defoamer to carry out froth breaking.Defoamer is widely used in removing the harmful foam producing in the industry production processes such as latex, textile sizing, food fermentation, biological medicine, coating, petrochemical industry, papermaking, industry cleaning link.
The stability of defoamer directly determines that defoaming effect finally can affect product quality.Existing defoamer just there will be the wild effects such as layering when temperature is higher.Existing traditional handicraft is not only complicated, and cost of manufacture is higher, does not meet the requirement of low-carbon environment-friendly.
Summary of the invention
The present invention has researched and developed a kind of high temperature resistant defoamer and preparation method thereof, and object is: by improving the high temperature resistant character of defoamer, thereby can make defoamer be used in some pyroreaction materials.
This technical scheme:
A kind of high temperature resistant defoamer, it is characterized in that, comprise following material: 50 parts of paraxylene, 50 parts of diphenyl-methanes, totally 5 parts of phenyl silicone oil, methyl phenyl silicone oil, any one or a few composition of MethylethoxylsiliconFluid Fluid, 1 part of polysorbate, totally 2 parts of polypropylene, polystyrene any one or two kinds of compositions.
A preparation method for high temperature resistant defoamer, is characterized in that, comprises the steps:
1), each 50 parts of paraxylene, diphenyl-methane are added in reaction vessel, heating-up temperature to 50 degree Celsius stirs 10 minutes, and mixing speed is 150rpm;
2), add totally 5 parts of phenyl silicone oil, methyl phenyl silicone oil, any one or a few composition of MethylethoxylsiliconFluid Fluid, heating-up temperature to 120 degree Celsius, improve mixing speed to 200rpm, mixing time is 15 minutes simultaneously, the standing 2-3 hour of sealing thermal insulation after completing;
3), add 1 part of polysorbate, keeping temperature is 120 degrees Celsius, improves mixing speed to 200rpm simultaneously, mixing time is 10 minutes;
4), add totally 2 parts of polypropylene, polystyrene any one or two kinds of compositions, heating-up temperature to 300 degree Celsius reduces mixing speed to 100rpm simultaneously, mixing time is 30 minutes, after completing, sealing is cooled to 40 degrees Celsius;
5), detect;
6), dry.
In described step 5), detection method is: sample thief adds in 2cm glass cuvette, by 300 high-temperature heating 30 minutes, by observing sample, whether has layering or occurs condensation product.
In described step 6), furnace drying method is centrifugal oven dry, and centrifugal condition is 4000r/min * 10min.
The invention has the beneficial effects as follows:
The defoamer that the present invention makes under 300 degree conditions is high temperature resistant, and stable chemical nature is nontoxic; And the oil source adopting is easy, price is low, uses simply, and environmentally safe, is convenient to transportation; The main material that adopts is savory can regulate some unpleasant products, is therefore widely used, and can be used for the fields such as chemical industry, printing and dyeing.
