The high-temperature silicon disulfide rubber reinforcing agent of art production is stablized with sodium metasilicate with modulus, and impurity is few, always measures the advantages that high admittedly, can replace
For the imported product of similar high value.
Summary of the invention:
The technical problem to be solved by the present invention lies in overcoming the defects of the prior art, provides a kind of high-temperature silicon disulfide rubber
The ultrapure sodium metasilicate of reinforcing agent.
The technical problems to be solved by the invention are realized using following technical scheme.
The ultrapure sodium metasilicate of high-temperature silicon disulfide rubber reinforcing agent, it is characterised in that: process flow is that quartz sand, soda ash-are mixed
Conjunction-calcining-molding-sodium silicate solid；
Chemical equation is Na2CO3+Si02-Na2Si03+CO2↑
Specifically: soda ash and quartz sand are uniformly mixed in 1:2 ratio, send into horse-shoe flame furnace, carries out at high temperature
Frit reaction is slowly flowed out by two sides fluid groove, is wandered to chain-and-slat forming machine, and feed liquid is divided automatically and is pressed into yin by pressure roller
In mould, it is shaped to blocks of solid, continues cool to head, is fallen in the feed bin of lower section, is transported to warehouse for finished product and is cooled to room temperature,
Sodium metasilicate is obtained, is put in storage.
Further technology: the soda ash and quartz sand incorporation time ± 30 seconds 3 minutes.
Further technology: pool depth is 1.6 meters in the horse-shoe flame furnace, dissolves area in 50 ㎡ or more, furnace
Equipped with two brunched burner nozzles, every alternating of automatic reverse in 30 minutes is primary, and two sides are equipped with offset dog-hole, and liquid surface height controlling is 1.45
Rice fluctuates < ± 5 centimetre, 3.8pa micro-positive pressure in furnace.
Further technology: 1510 DEG C ± 10 DEG C of frit reaction temperature.
Further technology: melting charge is after frit reaction, and the residence time is maintained at 36-38 hours in furnace.
Further technology: before the mixing step, testing to quartz sand and soda ash, and disqualified upon inspection is retracted,
Again quartz sand and soda ash are chosen, after the assay was approved weighing mixing.
Further technology: testing to sodium metasilicate before storage, examines qualified storage, unqualified to send into horse-shoe flame furnace
Calcining.
The utility model has the advantages that the high-temperature silicon disulfide rubber reinforcing agent of the technology of the present invention production is stablized with sodium metasilicate with modulus, it is miscellaneous
Matter is few, and total solid amount is high, is industry highest quality, the high-temperature silicon disulfide rubber reinforcing agent produced with product of the present invention, product original
Raw partial size can reach nanoscale, and 200 every gram of square meter of BET specific surface area makes with excellent dispersibility and very high specific surface area
Product has the high grade of transparency, high anti-yellowing excellent performance, and quality is stablized, and can substitute the imported product of similar high value.
