Abstract
The invention discloses a method for preparing a chlorosulfonated polyethylene anticorrosive paint. The product produced by the method has high acid and alkali corrosion resistance, and excellent ageing resistance and heat resistance. The chlorosulfonated polyethylene anticorrosive paint can applied to chemical buildings, cement walls, steel-framed bridges, chemical pipelines, tanks, inner and outer walls of acid, alkali and salt storage tanks, waterproofness of walls and floors of workshops, port terminals, reservoirs, sewage tanks, neutralization tanks and other facilities, inner and outer walls of urea and nitramine towers, surfaces of petroleum, oil refining and chemical buildings, equipment and oil tanks, oil delivery pipelines and oil tank cars and the like. Raw materials for producing the product comprise chlorosulfonated polyethylene resin, No.200 paint solvent and dimethylbenzene which are mixed in a ratio of 1:1, SG-01 active resin, gamboges, sodium carbonate, modified rosin resin, carbon black, a paint aid and barium stearate.
Description
Affiliated technical field:
Product of the present invention belongs to chemical field.Be specifically related to a kind of preparation method of chlorosulfonated polyethylene antifouling paste.
Background technology:
Chlorosulfonated polyethylene is made through superchlorination and chlorosulfonation by new LDPE (film grade) or high density polyethylene(HDPE).For white or yellow elastomerics, aromatic hydrocarbon and hydrochloric ether be can be dissolved in, but fat and alcohol are insoluble to, in ketone and ether, can only swelling can not dissolve.Chlorosulfonated polyethylene has excellent ozone resistance, resistance to weathering, chemical resistance etc.; Have better physical mechanical property, ageing-resistant performance, heat-resisting and lower temperature resistance, oil-proofness, flame resistivity, wear resistance, and anti-electrical insulating property.Can be applicable to fields such as building, automobile, industrial goods, electric wire, antifouling paste and tackiness agent, of many uses.The chlorine of chlorosulfonated polyethylene, sulphur content and polyethylene structure have tangible influence to it, significantly increase with the increase of cl content as its oil-proofness, but its winter hardiness descend.The chlorosulfonated polyethylene antifouling paste is to be main raw material by chlorosulfonated polyethylene resin, the priming paint of being made up of reactive resin, pigment, filler, auxiliary agent, organic solvent etc.This product has excellent acid, caustic corrosion, and remarkable ageing-resistant and resistance toheat is arranged.Can be used for: chemical building, cement wall surface, steelframe bridge, chemical pipeline and groove jar, equipment; Acid, alkali, salt basin inside and outside wall; The metope in workshop, terrace, the waterproof of facilities such as port and pier, reservoir, sewage lagoon, neutralization tank; Urea, nitramine tower inside and outside wall, the surface of oil, oil refining and chemical building, equipment, oil tank; Pipe laying, oils tank car etc. are made antifouling paste.Before the construction: substrate surface must fully be handled, and removes corrosion, dust, acid, alkali, water, oil must not be arranged, and clean, drying, coats then together to surfacer, if pitch time is longer, should polishes before application and prime for one time again.The priming paint overcoating generally is no more than one day interval, be advisable for one time every brushing in 30～40 minutes, till being coated onto the required number of plies, be coated with the back in normal temperature down curing can use after 10～14 days.
Summary of the invention:
The chlorosulfonated polyethylene antifouling paste is a kind of multiple raw-material anti-corrosion primer that can be used for, and this product has excellent acid, caustic corrosion, and remarkable ageing-resistant and resistance toheat is arranged.The invention provides a kind of preparation method of chlorosulfonated polyethylene antifouling paste.Producing the raw material that this antifouling paste uses has: chlorosulfonated polyethylene resin 20 parts (major ingredient), No. 200 varnish makers' and painters' naphtha and dimethylbenzene were by 1: 1 mixed 60 parts of (organic solvent), 5 parts of SG-01 reactive resins, gamboge 1 part of (pigment), 2 parts in yellow soda ash, modified rosin resin 4 parts of (tackifier), carbon black 4 parts of (filler), 2 parts of additive paints, 2 parts of barium stearates (stablizer).
A kind of production method of chlorosulfonated polyethylene antifouling paste, its beneficial effect is: technology is simple, production cost is low, quality is good, of many uses.
Embodiment:
Embodiment:
The first step: earlier No. 200 varnish makers' and painters' naphtha and dimethylbenzene are added letdown tank for 60 parts by the liquid of 1: 1 mixed, temperature is improved 50 ℃, start stirrer, add 20 parts of chlorosulfonated polyethylene resin particles slowly, insulated and stirred is to all dissolvings.
Second step: add 5 parts of SG-01 reactive resins, 1 part of gamboge, 2 parts in yellow soda ash successively, insulated and stirred reaction 1 hour.
The 3rd step: add 4 parts of modified rosin resins, 4 parts of carbon blacks, 2 parts of additive paints successively, continued stirring reaction 1.5 hours.
The 4th step: be cooled to normal temperature, add 2 parts of stirring reactions of barium stearate, stop after 0.5 hour stirring, obtain the chlorosulfonated polyethylene antifouling paste.
