Abstract
The invention relates to a low temperature-resistant pipeline anticorrosion hot-melt pressure-sensitive adhesive. The low temperature-resistant pipeline anticorrosion hot-melt pressure-sensitive adhesive selects high-quality butadiene styrene rubber, butyl rubber and imported hydrogenated glycerin resin, liquid tackifying resin, APAO, EVA, polyisobutylene and a proper amount of an antioxidant and an anti-oxidant. The low temperature-resistant pipeline anticorrosion hot-melt pressure-sensitive adhesive can be prepared through steps of fine banburying, open-milling, refining and kneading. The low temperature-resistant pipeline anticorrosion hot-melt pressure-sensitive adhesive is characterized in that the adhesive cannot be hardened at -30 DEG C, glue-spilling is not generated at high temperature, and the adhesive has strong adhesion stress and self-healing function, problems of nonstick anticorrosive cold winding tape and difficult construction at cold season can be solved, pipeline life is prolonged, through detection, other index can reach a national SY/T0410-2007 standard.
Description
Technical field
The present invention relates to a kind of low temperature resistant pipeline anticorrosion hot-fusible pressure-sensitive adhesive, use mainly for geographical or overhead metal pipe use in winter and northern cold climate environment, be suitable for the fields such as petrochemical complex, oil transportation natural gas line and electric power, coal, chemical industry, water conservancy, mining industry, sewage disposal.
Background technology
In piping installation, the buried underground of metallic conduit, its surface needs to carry out rotproofing, and the anticorrosion of routine is the method using anticorrosion adhesive tape voluble wrapping.Anticorrosive adhesive conventional is at present with polyethylene, polypropylene fortifying fibre adhesive tape, epoxy coal bitumen cold-tangled belt.Epoxide coal bituminous anticorrosive construction is slow, and waste of manpower cost is high, and polyethylene, polypropylene tape are anticorrosion more convenient.But there is microthermal climate cohesive force to decline, glue-line is hardening, and adhesive tape is wound around unreal, directly affects buried pipe preservative effect.In order to avoid this kind of problem occurs, a lot of engineering is once stopping construction to winter, constructing after waiting until the beginning of spring, such certainty just postpone engineering progress, have in order to ensure the duration, only be wound around having between heater car, but after pipeline moves on to outdoor, meet freezing air still can affect quality, hide some dangers for anticorrosion great cause.
Summary of the invention
The present invention, mainly in order to overcome the weak point of above-mentioned anticorrosion adhesive tape, provides one not climate temperature impact, the anticorrosion glue tape for pipeline that the whole year can construct.
The present invention is achieved through the following technical solutions:

According to upper illustration table, this low temperature resistant anticorrosion hot-fusible pressure-sensitive adhesive, the paint production technique method of fractional steps.One, make compound blank: mill on isoprene-isobutylene rubber, styrene-butadiene rubber(SBR) is rolled respectively thin 5-7 all over after be rolled into every pot appropriate equal portions leave standstill be greater than 48 hours, and then upper mill, with the composite elasticizer mixed in advance, complex antiager, calcene powder mixing friction base; Friction base will be mixed leave standstill after 48 hours again through row kneading finished product glue.
Two, manufacture a finished product glue: to get on three points of compound blanks mill rolling 5-7 and drop into kneader while hot all over (refining) and stir, then suitable equal portions hydrogenated rosin glyceride is got, terpine resin, liquid tackifying resins, APAO adds kneading, mediate and add filler after 40 minutes, if a certain equal portions quantity is more, can add several times, each feeding interval 10 minutes, cylinder temperature control does not exceed 140 degree, finally adds polyisobutene, mediates the adhesive tape to be coated that can take the dish out of the pot for 50 minutes after adding last defective material.
Eight, for the low temperature resistant anticorrosion hot-fusible pressure-sensitive adhesive of 500kg:
