Description
Technical Field
The invention relates to a preparation method of a modified polyphenylene sulfide material and a flange cushion cover prepared by the method.
Background
In the marine industry, ships are undoubtedly the most important tools and carriers, and during the marine process, the safety of the ships is of vital importance. However, since the ship hull, equipment, piping and other system components are usually made of different metals, which have different self-corrosion potentials in seawater, a metal contact corrosion (i.e., galvanic corrosion) occurs when they are in direct contact with and form a circuit with the surrounding medium. Particularly, the seawater pipe system in the ship is complex in material and equipment composition, so that the pipe system is often leaked due to galvanic corrosion caused by contact of dissimilar metals in a seawater medium, and the safety of the ship is seriously threatened. Therefore, electrical insulation treatment of ships is very important, namely, electrical insulation isolation must be carried out between all pipelines and accessories (valves, filters and the like) which are made of metal and have different port openings from the materials of the ship body and the ship body, and electrical insulation isolation must be carried out between different metal pipelines and accessories (valves, pumps, filters, coolers, equipment and the like) in the seawater pipeline system. The most important measure for this electrical isolation is to use various inert materials (including sealing materials) to make gaskets and sleeves, which are inserted into the flange connection to break the electrical conduction path between the cathode and anode of the two flanges, thereby preventing galvanic corrosion.
The flange gasket and the sleeve are made of a large number of inert materials including EPDM, FPM, PTFE, and the like, but since the conditions of seawater and the ocean are special and the requirements for the flange gasket and the sleeve are very high, polyphenylene sulfide (PPS) having excellent comprehensive performance is preferable. PPS is excellent in high temperature resistance, corrosion resistance, radiation resistance and flame retardance, and has balanced physical and mechanical properties and excellent electrical properties, so that PPS is widely used as special engineering plastics. However, with the development of marine technology, ship equipment is continuously updated, the requirement for corrosion resistance is higher and higher, the performances of density, hardness and the like of common inert material gaskets and sleeves are difficult to maintain in seawater immersion and high-pressure environments, and even PPS with excellent comprehensive performance has performance degradation, so that the phenomenon of seepage and leakage is caused. Therefore, a need exists for a gasket and a sleeve with excellent performance to meet the use requirements of ship equipment.
Disclosure of Invention
Aiming at the problems, the invention provides a preparation method of modified polyphenylene sulfide and a flange cushion cover prepared by the preparation method, wherein the existing polyphenylene sulfide is modified and then used for preparing the flange cushion cover, the density, the hardness, the bending strength, the tensile strength and the like of the flange cushion cover are effectively and greatly improved, and the use requirements of ship equipment are met. The specific technical scheme is as follows:

3-5 parts of silicon dioxide;
2-3 parts of an organosilane coupling agent.
The preparation method of the modified polyphenylene sulfide material comprises the following steps:
s1: preparation of Material I: stirring PPS and glass beads in a high-speed stirrer at a high speed for 2-3 min to obtain a material I;
s2: preparation of material II: stirring acrylonitrile-butadiene-styrene and silicon dioxide in a high-speed stirrer at a high speed for 2min to obtain a material II;
s3: preparation of material III: mixing the material I prepared in the step S1 and the material II prepared in the step S2 again, and stirring at a low speed for 2min to obtain a material III;
s4: preparation of Material IV: pouring an organosilane coupling agent into the material III prepared in the step S3, heating, and stirring at a high speed for 3-5 min to obtain a material IV; the organosilane coupling agent can improve the binding property of different materials, so that the intermiscibility of the materials is effectively improved.
S5: heat preservation modification: packaging and sealing the IV material prepared in the step S4 by using a packaging bag to prevent the organosilane coupling agent from volatilizing, and then, preserving heat in an oven for a time to complete the modification process to obtain a modified material;
s6: and (3) extruding and granulating: and (5) conveying the modified material subjected to heat preservation and modification in the step S5 into a single-screw extruder for extrusion granulation, so as to obtain the modified polyphenylene sulfide material.

During high-speed stirring, the materials collide and rub with each other, so that the surface temperature of the materials is increased, and heat is transferred mutually, so that the surface temperature of the materials is kept consistent, and uniform material mixing and subsequent reaction are facilitated. The purpose of stirring after mixing is to ensure that the first material and the second material are mixed more uniformly, and if high-speed stirring is still adopted, glass beads with larger specific gravity can not be uniformly mixed due to the centrifugal effect, so low-speed stirring is adopted.
