Abstract
The invention discloses a granulation binder for a rubber vulcanization accelerator DPG (diphenylguanidine) and a granulation method using the same. The granulation binder for a rubber vulcanization accelerator DPG is prepared from 80-100 parts of povidone, 50-65 parts of vinyl acetate, 40-50 parts of liquid paraffin, 1-5 parts of emulsifier, 0.5-1 part of polyvinyl alcohol, 0.5-1 part of dispersant, 0.1-0.5 part of sodium bicarbonate, 0.01-0.1 part of glycerin and 150-180 parts of water. The granulation method disclosed by the invention has the advantage of simple process, and can be easily industrialized. When the method is used for granulating the DPG product, the one-step granulation rate is higher than 80%, the average hardness is about 2N, and therefore, the DPG product can completely meet the customer requirements. The DPG granules can not be broken in the actual packaging or moving process. The assay measurement indicates that the quality indexes of the DPG granules conform to the national standard for first-grade products. The binder disclosed by the invention has the advantages of reasonable formula, strong compatibility with multiple rubbers, low consumption, favorable effect and high one-step granulation rate, and does not have any adverse effect on the physicochemical properties and vulcanization reaction properties of the product.
Description
Technical field
The present invention relates to the adhesive for granulating and the graining method for producing of a kind of thiofide vulkacit D (DPG), belong to the DPG technical field of granulating production.
Background technology
Vulkacit D PG mainly is used as the moderate accelerator of natural gum and synthetical glue.Be commonly used for the promoting agent of thiazoles, thiuram and time iodoxy class promotor,, can be used for endless vulcanization with altax, TMTD and time spent.The DPG material is thin partially, and static and dust phenomenon are particularly serious, and dust easily causes the human allergy, along with the increasingly stringent that requires of environmental protection management and industrial use, so powder-like product is more and more substituted by granulated product in industry.Granulated product and powder-like product relatively have following advantage: not having dust from flying in the use, is user friendly product; Granulated product does not have surface attachment, disperses easily, easier metering in the auxiliary agent product uses.The granulation of rubber ingredients is technological processs of the finished product of auxiliary agent production process, and the agglomeration technique level of the integral body of China's rubber ingredients is not high at present, and development is also uneven, and the ratio of granulation product is on the low side.That the auxiliary agent agglomeration technique comprises is oil-filled, non-slurry pelletizing, wet granulation, melt pelletization and the pre-dispersed granulation of carrier.The granulation of rubber ingredients all has crucial meaning to auxiliary agent factory and rubber mill, has reduced the pollution of dust, has increased the accuracy of source mill's batching, ensures that to improving the sizing material physicals quality product has played promoter action.
Two kinds of non-slurry pelletizing, wet granulations are generally adopted in present stage China DPG granulation.Non-slurry pelletizing is after DPG siccative and binding agent, water etc. are mixed in proportion, and through use the belt dryer drying after extruding or the spray method granulation, dry back product gets finished product after vibratory screening apparatus is handled.And wet granulation is after DPG wet feed and binding agent, water etc. are mixed in proportion, after granulation, drying finished product.Excessive or select improperly if add binding agent in granulation process, can cause particle really up to the mark, difficulty etc. during dispersion, but if do not add or add very little, then cause cohesive force not enough, granulating rate is too low, and particle scatters again in the transportation handling process, does not reach the granulation purpose.And granulated product in application process because problem such as there is the difficulties in dispersion inequality in the hardness problem of grain, and mixing time is long.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of vulkacit D PG adhesive for granulating and prilling process thereof, overcome that granulated pellet is really up to the mark, difficulties in dispersion, granulating rate is low and the unequal problem of granulated product difficulties in dispersion in application process.
The present invention is achieved by the following technical solutions: a kind of thiofide DPG adhesive for granulating, adopt following compositions in portion by weight to form:
Polyvidone: 80-100 part
Vinyl acetate: 50-65 part
Whiteruss: 40-50 part
Emulsifying agent: 1-5 part
Polyvinyl alcohol: 0.5-1 part
Dispersion agent: 0.5-1 part
Sodium bicarbonate: 0.1-0.5 part
Glycerol: 0.01-0.1 part
Water: 150-180 part
Wherein: emulsifying agent is polyoxyethylene nonylphenol ether, polyoxyethylene octylphenol ether, octadecane alcohol radical Soxylat A 25-7 etc.
Dispersion agent is sodium laurylsulfonate, tripoly phosphate sodium STPP, fatty acid polyglycol ester etc.
A kind of thiofide DPG prilling process may further comprise the steps:
At first, binding agent is added in the DPG wet feed (moisture≤25%), after stirring, add in the tablets press, make wet product material from the head die plate hole, extrude the cylindrical particle that uniform diameter is 2 ± 0.2mm by screw rod transmission;
Secondly,, separate grain and powder with vibration screen through 80-95 ℃ of drying of belt dryer, the direct finished product packing of granular product on the screen cloth, powder returns in the agitator kettle stirring-granulating again under the screen cloth.
The mass percent that the add-on of described binding agent accounts for DPG material dry product is 1 ‰～2%.
Beneficial effect of the present invention is: this method is directly carried out granulation by the DPG wet feed, avoided dry problem twice, manpower and materials have been saved, reduce energy consumption, in granulation process, added a kind of novel binding agent, made granulating rate height of material, gained DPG grain intensity is big, Pulverization ratio is low, but to the physicochemical property of product and vulcanization reaction character without any influence, meet the environmental protection policy of country.Use granulating rate of this method granulation DPG product up to more than 80%, average hardness can reach customer requirements fully about 2N, the grain breakage phenomenon do not occur in the packing moving process.The DPG grain is after chemical examination is measured, and its quality index meets country-level product standard.This DPG granulated product is not observed serious dust from flying phenomenon in mixing process, do not find to mix uneven phenomenon, compares with powder-like product, and DPG grain mixing time, vulcanization rate, time of scorch, tensile yield etc. all do not have significant difference.Owing in binding agent, added a spot of dispersion agent, to compare with other DPG granulated products, its application performance (mixing time, vulcanization rate, time of scorch, tensile yield etc.) has certain advantage.This procedure is simple, is easy to industrialization, and binder formula is reasonable, contains binding agent, linking agent, dispersion agent, swelling agent etc., and all very strong with the consistency of multiple rubber, consumption is few, and is effective, granulating rate height of product, and product performance are not had influence.
