Abstract

The invention relates to a defoaming agent for polystyrene. The defoaming agent is prepared from, by weight, 2-4 parts of dimethyl silicone oil, 1.2-1.5 parts of sodium dodecyl benzene sulfonate, 2-3 parts of diphenyl carbazone, 2.5-4 parts of sodium tripolyphosphate, 3-5 parts of triethanolamine, 4-6 parts of dispersing agent NNO and 2-3 parts of chlorinated paraffin. After the defoaming agent for polystyrene is matched, the defoaming agent is reasonably matched aiming at the characteristics of polystyrene materials, the bubble generation rate of polystyrene products in the processing process is reduced, the quality of the products is improved, the yield of the products is increased, the defects of the products are reduced, and meanwhile the physical performance of polystyrene cannot be reduced.

Description

A kind of polystyrene defoamer
Technical field
The invention belongs to plastics additive field, be specifically related to a kind of polystyrene defoamer.
Background technology
Polystyrene resin is nontoxic, odorless, colourless transparent grain, and like glassy hard brittle material, its goods have high transparency, and transmittance can reach more than 90%, and electrical insulation capability is good, easy coloring, and processing fluidity is good, good rigidly and chemical resistance good etc.The being property of weak point of ordinary polystyrene is crisp, and shock strength is low, easily occurs stress cracking, poor heat resistance and not resistance to boiling water etc.In the polystyrene course of processing, need to add defoamer and reduce bubble rate in the course of processing, improving product rate, but the defoamer effect of the single formula of existing use is poor, affects yield rate.
Summary of the invention
The object of this invention is to provide a kind of polystyrene defoamer, promote defoaming effect, promote yield rate.
The present invention is achieved through the following technical solutions:
A kind of polystyrene defoamer, is made up of the raw material of following weight part: dimethyl silicone oil 2-4 part, Sodium dodecylbenzene sulfonate 1.2-1.5 part, diphenyl carbazone 2-3 part, tripoly phosphate sodium STPP 2.5-4 part, trolamine 3-5 part, sodium metnylene bis-naphthalene sulfonate 4-6 part, clorafin 2-3 part.
Preferably, a kind of polystyrene defoamer, is made up of the raw material of following weight part: dimethyl silicone oil 3.2 parts, Sodium dodecylbenzene sulfonate 1.4 parts, diphenyl carbazone 2.8 parts, tripoly phosphate sodium STPP 3.2 parts, trolamine 4.2 parts, sodium metnylene bis-naphthalene sulfonate 5 parts, clorafin 2.6 parts.
Time prepared by defoamer, raw material is used forcing machine granulation after mixing.
Beneficial effect of the present invention: polystyrene defoamer provided by the invention is by after proportioning, for the characteristic of polystyrene material, rational proportion defoamer, reduce bubble production rate in the course of processing of modified styrene polymer, promote quality and the yield rate of goods, reduce the generation of product defect, also the physicals of p-poly-phenyl ethene can not cause decline simultaneously.
Embodiment

Comparative example 1
A kind of polystyrene defoamer, is made up of the raw material of following weight part: diphenyl carbazone 2.8 parts, tripoly phosphate sodium STPP 3.2 parts, trolamine 4.2 parts, sodium metnylene bis-naphthalene sulfonate 5 parts, clorafin 2.6 parts.
Comparative example 2
A kind of polystyrene defoamer, is made up of the raw material of following weight part: dimethyl silicone oil 3.2 parts, Sodium dodecylbenzene sulfonate 1.4 parts, diphenyl carbazone 2.8 parts, tripoly phosphate sodium STPP 3.2 parts, trolamine 4.2 parts.
Comparative example 3
A kind of polystyrene defoamer, is made up of the raw material of following weight part: dimethyl silicone oil 3.2 parts, Sodium dodecylbenzene sulfonate 1.4 parts, trolamine 4.2 parts, sodium metnylene bis-naphthalene sulfonate 5 parts, clorafin 2.6 parts.
The defoaming effect that defoamer prepared by the present invention adds man-hour at polystyrene is as follows, defoamer add-on is 0.2% of polystyrene material weight, uses mixed material to prepare fan blade, statistics goods bubble decrement and yield rate, not add defoamer for contrast, result is as following table:
Defoamer kind Bubble decrement (%) Yield rate (%)
Embodiment 1 96.2 99.96
Embodiment 2 96.1 99.82
Embodiment 3 95.4 99.91
Comparative example 1 82.3 96.75
Comparative example 2 76.3 95.42
Comparative example 3 83.2 96.26
Sodium dodecylbenzene sulfonate 84.5 97.45
Do not use defoamer / 95.21
Table 1.
As seen from the above table, the defoaming effect of the defoamer of proportioning of the present invention is obviously better than common defoamer, and can promote the yield rate of modified styrene polymer.
