Abstract
The long-acting preserving and sealing protection method has double-layer preserving and sealing structure adopted including an outer layer of rubber jacket and an inner layer of preserving and sealing glue to adhere the rubber jacket and the protected part integrally. The present invention is especially suitable for use in preserving and sealing protection of gas cylinder joint, pipeline, flange joint, nut and screw bolt in ships.
Description
One, technical field
The present invention relates to a kind of long-acting preserving and sealing protection method, adopt double layer construction, form, be used for preserving and sealings such as pipeline connection, gas cylinder joint, nut and bolt, belong to technical field of sealing technology by rubber sleeve and sealer.
Two, background technique
Connect (flange) by the various pipelines in thousands of places on the boats and ships, the bolts (spiral shell emits) of most amounts etc., owing to be subjected to sea water immersion for a long time, alternation of wetting and drying, high and low temperature alternative are frequent, very easily cause seawater oxide etch, the potential corrosion at unlike material position is also very serious in addition.Anti-corrosion method commonly used is to adopt the rust proof paint brushing on the boats and ships, has proved and can not satisfy long-term requirement for anticorrosion.Also there are boats and ships to adopt direct coated underwater components such as epoxy mortar, polysulfide sealant or polyurethane clay, reach preserving and sealing purpose (Chemical Industry Press: Huang Yingchang and Lv Zhengyun write " elastic sealant and adhesive ").But epoxy mortar not high-low temperature resistant impacts, and elasticity is very poor, and is easy to crack.Polysulfide sealant elasticity is good, and anti-ozone and weather resisteant are good, oil resistance is excellent, water-tolerant, the moisture breathability is low, contractibility is little, but when construction for regulating thixotropy, add mass filler, influence cementability, the posterior spiracle of constructing is more, has influenced sealing effect.Conventional polyurethanes clay oil resistant, wear-resisting, intensity is high, good springiness, radiation resistance are good, but heat resistance is not high, shortcoming is the effect of thermo-labile water, water vapour, strong bronsted lowry acids and bases bronsted lowry, unsuitable preferred material as long-term underwater sealing." petrochemical equipment " 2000 the 1st phases have been introduced a kind of sealing configuration that is used for stainless steel railway tank car manhole flange, adopt the compound gasket form, are made up of rubber inner ring and plastic peel, by crush seal.
Three, summary of the invention
The object of the invention provides a kind of New-type long-acting preserving and sealing protection method, and material therefor and metal or common rust proof paint matching are good, and cementability is strong; Have favorable elasticity, high-low temperature resistant (40 ℃～100 ℃), ageing resistance are good; Anti-alternating pressure, vibration resistance, sea water resistance or oil resistant corrosion; Easily change, life cycle is long, normal temperature cure, and construction technology is strong.
For achieving the above object, the present invention adopts the double layer anticorrosive sealing configuration, is made up of rubber sleeve and sealer.The outer layer rubber overcoat is a main raw material(s) with anti-marquis, rubber water-fast, excellent combination property, as nitrile butadiene rubber, neoprene, styrene butadiene rubber, butyl rubber and Thiokol, be sulfided into closely knit prefabricated rubber sleeve, play anticorrosion water proof and fixed profile; Internal layer filling preserving and sealing glue as polysulfide sealant, polyurethane sealant, silicone sealant, sticks to one prefabricated rubber sleeve and sealed guard block, increases anticorrosion water proof effect, plays bonding and seal action, reaches the purpose of double-deck protection.
During practical application,, design the thick 3-8mm of prefabricated rubber sleeve according to the caliber of joint to be protected or flange, the outer surface fairing, internal surface is the irregularity zigzag fashion, can increase the area of contact with preserving and sealing glue; Rubber sleeve is two semicircle cavity configurations, and inner chamber radius ratio joint to be protected or the big 3-10mm of flange caliber guarantee size with mould.During sealing, filling preserving and sealing glue in advance in the semicircle chamber, and latter two semicircle chamber closes up, and is enclosed within on joint or the flange, with larynx hoop or adhesive tape locking, scrape off the sealer of extruding, before the curing, must guarantee that sealant layer is not shifted, and after treating to solidify fully, removes larynx hoop or adhesive tape and gets final product.

Five, specific implementation method
Example 1: flanged joint preserving and sealing protection
The preserving and sealing double shielding structural representation of Fig. 1 flanged joint.Outer neoprene overcoat is prefabricated into the thick semicircular cavity structure of 5mm, after only need be filled with cavity with polysulfide sealant during construction, closes up two semicircles and with the locking of larynx hoop, scrapes off unnecessary sealer, after treating to solidify fully, removes the larynx hoop.The inside and outside two-layer duplicate protection of sealing structure, antiseptic effect is very effective.During repair demolition, only need to sever rubber outer along closing up seam, the sealer that scrapes off in the chamber gets final product, and the neoprene overcoat is reusable.
After this long-acting preserving and sealing protection method practical application, the beautiful shape fairing, easy construction, anticorrosion water proof is long-acting, and real ship uses and surpasses 5 years, and protected parts are intact, do not find the seepage phenomenon.
Example 2: bolt oil resistance anticorrosion sealing applications
The preserving and sealing double shielding structural representation of Fig. 2 bolt.The nitrile butadiene rubber overcoat is designed to the cylindrical cavity structure of end sealing, and thickness is 3mm.Inner layer material is selected oil resistance excellence, polyurethane sealant that adhesive property is strong for use, during construction polyurethane sealant injected cavity after, be enclosed within on the bolt, scrape off unnecessary polyurethane, compress with adhesive tape, after treating to solidify fully, remove adhesive tape.
Example 3: gas cylinder preserving and sealing protection
The double shielding structural representation of Fig. 3 gas cylinder joint; the average thick 5mm-10mm of outer styrene butadiene rubber overcoat, semicircular cavity structure, outer surface fairing; internal surface is according to joint caliber difference; be designed to flexuose, the vestibule internal diameter is on average greater than caliber 8-10mm, during construction silicone sealant filled with cavity after; close up the two halves cylindrical cavity and lock with the larynx hoop; scrape off unnecessary sealer, after treating to solidify fully, remove the larynx hoop.
