Description
Technical field
The present invention relates to vci field, espespecially a kind of composition for the preparation of polyvinyl chloride thermal contraction gas-phase antirusting film.
Background technology
At present the method for industrial the most frequently used rust protection, is in metallic surface, to apply slushing oil, but this method can lose efficacy because of oxidation because of slushing oil itself, time-consuming during removal protective layer, take a lot of work, both unhygienic also dangerous.Adopt that the antirust cost of desiccant is low, simple to operate, safety and environmental protection, removal protective packaging be easy, but working lipe is short, and is subject to the impact of envrionment temperature large.With special dehumidification equipment, pack and process metallic substance to what, although rust-proof effect is pretty good, cost is high and waste time and energy, complicated operation.Not only easy but also practical, not only safe but also effective volatile rust prevention packing more and more causes people's concern.
Vapour-phase inhibitor is through special synthesis technique, the composite a kind of corrosion inhibitor being prepared from.It can separately or depend on suitable carrier, at normal temperatures and pressures direct gasification.In sealed environment, by self adjustable lasting volatilization, make in the gap, any space in operation unit; the full mixed gas that contains the volatile rust prevention factor in capital; this gas can adsorb on it while meeting with metallic surface, forms and only has one or the thick fine and close protective film of several molecule.This protective film can effectively completely cut off contacting of metallic surface and moisture, oxygen and other harmful atomospheric corrosion factors, suppresses to impel the generation of the electrochemical reaction of metallic corrosion, thereby reaches best rust protection effect.This novel rush-resisting material, by what, it has rapid, simple and easy, feature cheaply on the antirust preservation of full scale plant is processed, and especially meets environmental requirement, is subject in recent years more multiple looking, compare with traditional rust-proofing method, volatile rust preventive material has many unrivaled advantages.At metallic substance, pack or sprayed Hou, vapor phase corrosion inhibitor agent molecule just starts to disperse, and vapor phase corrosion inhibitor agent molecule may penetrate into the corner space that traditional slushing oil cannot cover, antirust without dead angle; Vapor phase corrosion inhibitor molecule effective constituent retention time is long; Even if metallic surface has moisture or outside air very moist, rust-preventive agent also can form protective film in metallic surface, prevents from that metal is corroded to get rusty; The Gas permeability of the rustproof packaging material of making and Water Vapour Permeability are extremely low, have waterproof, protection against the tide, oil resistant, chemical resistant characteristic.Particularly when packing metallic substance, mechanical means and part, use vapor phase inhibitor need not smear slushing oil, also needn't process in addition, greatly simplified etch-proof loaded down with trivial details step, compare with vacuum packaging, both realized special corrosion proof function, reduce again packing cost, save artificial and material, raise the efficiency.
Antirust film is to take the plastics film that carrier that plastics are vapor phase inhibitor produces, and according to the special formulation that contains vapor phase inhibitor, adopts the conventional production method of thermal shrinked thin-membrane with polyvinyl chloride, can produce PVC gas phase anticorrosive thin film of thermal contraction.
Summary of the invention
A kind of composition for the preparation of polyvinyl chloride thermal contraction gas-phase antirusting film of the present invention, it is characterized in that, utilization includes the composition for the preparation of polyvinyl chloride thermal contraction antirust film of vapor phase inhibitor, adopt the conventional production method of thermal shrinked thin-membrane with polyvinyl chloride, can produce polyvinyl chloride thermal contraction antirust film, to realize the object of conveniently producing and reaching volatile rust prevention requirement.
To achieve these goals, technical solution of the present invention is: a kind of composition for the preparation of polyvinyl chloride thermal contraction gas-phase antirusting film comprises polyvinyl chloride (PVC) RESINS, softening agent, stablizer, extender plasticizer, impact modifier, polyvinyl resin, phosphoric acid hexahydroaniline, lipid acid dicyclohexyl amine, morpholine derivative and lubricant, and each component and weight part thereof are:
Further, described polyvinyl chloride (PVC) RESINS is six types that suspend or the seven type resins that suspend.
