Abstract
The invention relates to a preparation method for a sulfur microemulsion, which comprises the following steps: evenly mixing tetrahydronaphthalene with an anthracene solvent in the weight ratio of (20-80):1 in a reaction kettle; adding sulfur while stirring is performed; stirring for 5-60 minutes under controlling the temperature to be 20-90 DEG C; and then, removing the undissolved sulfur to obtain the sulfur microemulsion, wherein the maximum dissolvability of the sulfur reaches 19.11g in every 100g of solvent. According to the preparation method for the sulfur microemulsion, very good dissolving power can be performed on the sulfur under the required temperature after the tetrahydronaphthalene and the anthracene solvent are mixed; the dissolvability of the sulfur microemulsion on the sulfur exceeds that of all industrial sulfur solvents on the sulfur except for carbon disulfide, but the toxicity of the sulfur microemulsion is far lower than that of the carbon disulfide and all the industrial sulfur solvents.
Description
Technical field
The invention belongs to rubber industry and paper industry field, be specifically related to a kind of sulphur preparation of microemulsion method.
Background technology
The rubber sheet gasketing of producing with paper process is applied in industry, various fields of recent life; Its basic procedure is to be medium with water, in water, disperses fibrous material, adds filler breast, vulcanizing agent, filler etc. then; The moulding of on the paper machine, manufacturing paper with pulp is again through high temperature vulcanized process.Sulphur plays an important role to performance of products as main vulcanizing agent.In the process of manufacturing paper with pulp, sulphur is because of water insoluble easy loss, and the particle Sulfur is difficult in paper, form uniform distribution, through the sulphur microemulsion is processed in sulphur dissolving, emulsification, can improve the cure efficiency and the quality product of product.Dithiocarbonic anhydride is acknowledged as the optimum solvent of sulphur, but shortcomings such as dithiocarbonic anhydride is volatile, inflammable, explosive, strong toxicity are brought a series of safety and environmental protection problems to industrial production.The industrial sulphur solvent that exploitation in recent years is used for alternative dithiocarbonic anhydride has zellon, tetracol phenixin, toluene and various double solventss etc.Though these solvent toxicity are lower than dithiocarbonic anhydride,, can not satisfy sealing material far away to the deliquescent requirement of sulphur to the dissolving power of the too late dithiocarbonic anhydride of the dissolving power of sulphur to sulphur.
Summary of the invention
The object of the present invention is to provide that a kind of toxicity is low, boiling point is high, not volatile, big sulphur preparation of microemulsion method to sulphur solubleness.
For achieving the above object; The technical scheme that the present invention adopts is: in reaction kettle with naphthane with fear solvent with mass ratio 20-80: 1 mixes; Add Sulfur while stirring, controlled temperature 20 ℃-90 ℃, stir the 5-60min after-filtration and remove undissolved sulphur and obtain the sulphur microemulsion.
Prepared sulphur microemulsion reaches the 19.11g/100g solvent to the sulphur maxima solubility.
The present invention has good dissolving power to sulphur with naphthane with after fearing mixing under the temperature that requires; The solubleness of sulphur is surpassed except that dithiocarbonic anhydride all industrial sulphur solvents to the solubleness of sulphur, but toxicity is far below dithiocarbonic anhydride and various sulphur industrial solvent.
