According to the preparation method of high-temperature stable coated sulfur provided by the invention, the production process is simple, the equipment investment is small, and the discharge of three wastes is avoided in the production process.
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 preparation method take composite high-molecular material as the coated high-temperature stability sulphur of film material.
Background technology
Up to the present, the widely used vulcanizing agent of tire and rubber industry is mainly insoluble sulfur.Insoluble sulfur has Heat stability is good under the processing condition of compounding rubber (100-120 ℃) (can be resistance to 120 ℃, 15 minutes), the feature of good dispersity, therefore the sizing material work in-process performance of making is good, surface no blooming, but the production of insoluble sulfur is to be gasified through high temperature (400-600 ℃) by common sulphur, after thermal excitation open loop (common sulphur is 8 S8 ring texturees that S courtyard is connected) pump closes, again by the crystallization of dithiocarbonic anhydride fire, through dithiocarbonic anhydride, washing is removed after the steaming of solubility sulphur more afterwards, 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, all there is blast in every step, 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 is take composite high-molecular material as the coated high-temperature stability sulphur of film material.
The present invention realizes 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 under whipped state, add dispersedly 50 parts of common SULPHUR POWDER, 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 the high-temperature stable steamed stuffed bun sulphur of the above, in described step (1), HBA-400, vinyl-pyridine latex, pure aluminium silicate, silicon-dioxide and water weight part proportioning 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, in described step (1), HBA-400 elastic emulsion is the anionic emulsion of acrylate and specific function monomer copolymerization.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 pure 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 ℃.
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, insoluble sulfur that completely can 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, filtered water circular batching uses without any pollutent and discharges, and therefore, is a kind of advanced person's low-cost environmental-protecting new preparation process.
