Description
Technical field
The invention belongs to chemical technology field, relate to a kind of preparation method of high-temperature stable steamed stuffed bun sulphur, specifically a kind of take composite high-molecular material as the preparation method of film material and coated high-temperature stability sulphur.
Background technology
Up to the present, tire and the widely used vulcanizing agent of rubber industry mainly insoluble sulfur.Insoluble sulfur has Heat stability is good under the processing condition of compounding rubber (100-120 DEG C) (can be resistance to 120 DEG C, 15 minutes), the feature of good dispersity, therefore the sizing material work in-process performance made is good, surface no blooming, but the production of insoluble sulfur is gasified through high temperature (400-600 DEG C) by common sulphur, after thermal excitation open loop (common sulphur is the S8 ring texture that 8 S courtyards are connected) pump closes, again by the crystallization of dithiocarbonic anhydride fire, afterwards again after dithiocarbonic anhydride washing removing solubility sulphur steams, drying again, pulverize, sieve, the operation such as oil-filled is made, production process is through high temperature, solvent extraction is dry, pulverize, the various process such as screening, often walk and all there is blast, the hidden danger such as on fire, working condition is very harsh, production cost is also just very high, therefore product price is also higher.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of preparation method of high-temperature stable steamed stuffed bun sulphur, this high-temperature stable steamed stuffed bun sulphur take composite high-molecular material as film material and coated high-temperature stability sulphur.
The present invention is realized by following technical scheme:
A preparation method for high-temperature stable steamed stuffed bun sulphur, comprises following step:
(1) by HBA-400, vinyl-pyridine latex, pure aluminium silicate, silicon-dioxide and water by weight ratio drop into mixing tank stir;
(2) then add common SULPHUR POWDER 50 parts dispersedly under whipped state, stir after 1 hour, filter, then in constant dry dehydration to moisture <0.3%, through pulverizing, sieve the coated sulphur of sub-compound cutan that secures satisfactory grades.
In the preparation method of upper described high-temperature stable steamed stuffed bun sulphur, in described step (1), HBA-400, vinyl-pyridine latex, pure aluminium silicate, silicon-dioxide and water weight are HBA-400: vinyl-pyridine latex: pure aluminium silicate: silicon-dioxide: water=4-6:4-6:4:4:500.
In the preparation method of above-mentioned high-temperature stable steamed stuffed bun sulphur, the anionic emulsion of HBA-400 elastic emulsion system's acrylate and specific function monomer copolymerization in described step (1).Its film has good extensibility, rebound resilience, water tolerance and good low temperature flexibility, and alkali resistance, sticking power and closed performance are also fine
In the preparation method of above-mentioned high-temperature stable steamed stuffed bun sulphur, described step (1) mesosilicic acid aluminium is nanometer aluminium silicate.
In the preparation method of above-mentioned high-temperature stable steamed stuffed bun sulphur, in described step (1), silicon-dioxide is nano silicon.
In the preparation method of above-mentioned high-temperature stable steamed stuffed bun sulphur, in described step (2), constant dry dehydration temperature is 80 ± 5 DEG C.
Beneficial effect of the present invention is:
(1) the coated sulphur that prepared by the preparation method of high-temperature stable steamed stuffed bun sulphur of the present invention is a kind of high-temperature stability sulphur, and experimental result shows, this good product dispersibility, no blooming, completely can the insoluble sulfur of substituting import one.
(2) preparation method of high-temperature stable steamed stuffed bun sulphur of the present invention, production technique is simple, and facility investment is few, production process three-waste free discharge, and filtered water circular batching uses and discharges without any pollutent, therefore, is the low-cost environmental-protecting new preparation process of a kind of advanced person.
