Abstract
The invention provides a high temperature and corrosion resistant lining and a preparation method thereof. The high temperature and corrosion resistant lining is prepared from ethylene-propylene-diene rubber, styrene-butadiene rubber, a vulcanizing agent, stearic acid, white carbon black, sulfur, an accelerating agent, an anti-ageing agent, a filling agent and a softening agent. The preparation method of the high temperature and corrosion resistant lining comprises the following steps: mixing the components for preparing the high temperature and corrosion resistant lining to obtain a compound, filtering the compound, pressing and molding the cold feed to obtain a corrosion resistant rubber plate, lining the obtained corrosion resistant rubber plate by adopting a thermal cauterizing method to obtain a rubber lining, and vulcanizing the rubber lining to obtain the corrosion resistant ethylene propylene rubber lining. The lining provided by the invention can be used for tanks to resist acids, alkalis, ammonia, chlorine and oxidants, and the lining can resist the high temperature of 100 DEG C.
Description
Technical field
The present invention relates to chemical anticorrosion Material Field, be specifically related to a kind of high temperature resistant, applied corrosion resistant lining and preparation method thereof.
Background technology
The eighties in 20th century, domesticly introduced many viscose glue production lines, wherein ten primary flash apparatus body have revealed efficient, energy-conservation and stability, bring new technological breakthrough to domestic viscose glue industry.But import equipment price is high, become the bottleneck of the domestic viscose glue industry development of restriction.Therefore, the production domesticization seeking ten primary flash devices becomes the task of top priority.The exploitation of the antiseptic rubber lining matched with it is also brought into schedule as one of key factor.
The rubber anti-corrosive lining sold in the market, as natural rubber lining, chloroprene rubber lining, isoprene-isobutylene rubber lining, in technique except adopting traditional hot high pressure sulfuration production technique, have also appeared normal pressure hot sulfurization, the novel process rubber linings such as direct atmospheric steam vulcanizer automatization.Although these lining materials all greatly meet chemical anticorrosion need high temperature resistant, resistant to corrosive media, if the acid-alkali mediums such as sulfuric acid, hydrochloric acid, phosphoric acid, caustic soda are to the corrosion requirement of steel equipment.But, in actual applications, because medium is not often single, sometimes be mixed with solvent oil, as the water treating equipment of environmental protection industry (epi), and usually use in medium in the equipment such as oil equipment and food-processing and cause great danger, make the swelling damage of lining material, cause rubber lining not corrosion-resistant, work-ing life is short, anticorrosion safe and reliable not.
Summary of the invention
The one that the object of this invention is to provide is high temperature resistant, applied corrosion resistant lining and preparation method thereof.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
(1) obtain glue stuff compounding by mixing for described a kind of each component that is high temperature resistant, applied corrosion resistant lining, then obtain antiseptic rubber offset plate by cold feeding extrusion molding after being filtered by gained glue stuff compounding;
(2) step (1) gained offset plate is carried out lining by Thermocauterization and paste to obtain line with rubber;
(3) step (2) gained line with rubber is carried out sulfuration and namely obtain a kind of high temperature resistant, applied corrosion resistant lining.
Beneficial effect of the present invention:
(1) the present invention is compared with domestic like product, and thermotolerance significantly improves; Compared with same kind of products at abroad, actual use temperature also improves; Have good toughness and lower temperature resistance simultaneously concurrently, reduce the requirement of vulcanite lining products for storing, improve economic benefit.
(2) the present invention is by specific component and consumption, improve the performance of existing vulcanite, the one obtained by described composition be high temperature resistant, applied corrosion resistant lining, resistance toheat is good, in acid solution, actual use temperature can reach 110 DEG C, and in saturation steam, actual use temperature can reach 130 DEG C; Can life-time service reach the condition of-900KPa in vacuum tightness under.Gained antiseptic rubber lining has good resistant to chemical media corrodibility simultaneously.In addition, lower temperature resistance also improves, and reaches the rubber lined low-temperature performance of semi-rigid (-5 DEG C), is on the leading domestic level, reach the advanced level of same kind of products at abroad.
