Description

A kind of anti-icing paint and purposes
Technical field
The present invention relates to a kind of anti-icing paint and purposes.The invention belongs to chemical, material technology field.
Background technology
Along with the fast development of modern industry, more and more higher to the reliability requirement of mains supply.Icing and accumulated snow are a kind of spontaneous phenomenons, yet are natural disasteies for the power system icing, and the safe operation of power system in the serious threat of circuit icing.The harm that powerline ice-covering causes power system comprises machinery and electrical hazards such as conductor galloping, broken string, shaft tower collapse, flashover.The safe and reliable operation of electric power and network of communication in the serious threat of powerline ice-covering accumulated snow.
In general, the icing phenomenon of lead wherein mainly comprises factors such as temperature, humidity, cold and heat air convection current, circulation and wind speed owing to various meteorological reasons form.Contain supercooled water droplets winter in the rain, this water droplet is extremely unstable, because of the existence that does not have the nuclei of crystallization exists with liquid form, in case drop on the lead, lead will make super-cooling waterdrop freeze rapidly and cover on the lead as the effect of the nuclei of crystallization, form so-called icing.From forming mechanism, icing can be divided into following several: the steam in (1) atmosphere adheres to when supersaturation and distillation is condensed, and the radial crystallization of formation is called rime.In general, water droplet freezed in advance than the needed time of combining closely mutually when rime formed, and had formed the exsiccant ice that comprises many spaces or bubble.Therefore, such ice concentration is less, and is also more open.(2) super-cooling waterdrop in the atmosphere forms limpid smooth transparent icing and is called glaze in the windward side of lead.The time of the time ratio collision of this class droplets freeze will be grown.Therefore, the icing of formation is smooth, and density is bigger and tight, and with the strong adhesion of lead.(3) super-cooling waterdrop forms the transparent and opaque ice sheet that replaces overlapping or similar obscure glass in the windward side.The sticking power of this class icing is also bigger, generally is difficult to remove.
The harm of icing is that people are obvious to all, and that people also strive to find is economic and practical, the method for environmental protection, workable control icing.At present, the anti-icing paint development is one of main direction of anti-icing.Mainly comprise photo-thermal type anti-icing paint, electroheating type anti-icing paint and hydrophobic type coating three classes.Photo-thermal type anti-icing paint improves the temperature of lead by absorbing sunlight, thereby makes conductor temperature above freezing at water, thereby reaches the requirement of anti-icing.This class coating is owing to limited by the weather reason, and at the weather of ice and snow, general light is not strong, is difficult to play due effect, so study lessly, application prospect is less.The electroheating type anti-icing paint keeps the temperature of lead by the electric heating on the lead, thereby makes lead above freezing at water.This class coating generally is to mix a small amount of conducting material in coating, thereby makes coating form semi-conductor layer, produces electric heating thereby lead forms small stray current.This type of coating is because bigger to the loss of electric energy, and application prospect has certain restriction.Therefore, the practicality of photo-thermal type and electroheating type anti-icing paint is relatively poor.Yet hydrophobic type coating passes through to reduce the bonding force between water or ice and the lead, thereby prevents to freeze.The type coating reduces ice to the sticking power of substrate surface and the ice cover on surface by be coated with the coating of anti-icing at substrate surface, utilizes phoenix and elemental effect to make ice break away from substrate surface easily again.These class methods are simple, cost is low, can play the effect that reduces ice damage in a lot of places.Even if in the time of under extreme conditions need adopting artificial deicing, also because of ice is little to substrate surface sticking power, work difficulty can greatly reduce.
In aforesaid method, prepare anti-icing paint as employing organic fluorinated silicone macromolecular materials such as CN1010358106A, CN101230224A, US20020139956A1 and CN101514270A, this coating can effectively reduce water and the sticking power of ice in conductive line surfaces, and effect is limited in the anti-ice practice of reality.Method by the anti-ice cover coating that increases contact angle is described, in anti-ice cover is used, certain effect is arranged, but be difficult to large-scale application in production practice.
Anti-ice cover coating of the present invention is when reducing ice sheet and lead sticking power, by the ion of polyelectrolyte electrolysis generation, reduce the freezing point of water with this, postpone icing effect thereby reach, after exceedingly odious environment lower wire freezes, can quicken ice-melt simultaneously.Therefore, anti-ice cover coating of the present invention has anti-ice cover practical function preferably.
Summary of the invention
The present invention is directed to China's power system icing incidence height, the characteristics that hazardness is big provide a kind of effective anti-icing paint and purposes.With organic-silicon-modified sodium polyacrylate is the coating of main component, has: (1) and the good sticking power of lead, and do not have corrosion; (2) in sleety weather, the ion that polyacrylate ionization goes out can effectively delay to freeze; (3) have deicing property by force, can accelerate the ice-melt time, reduce the sticking power of ice sheet and lead, improve the icing ability of lead.
Technical scheme provided by the invention provides a kind of anti-icing paint, form by organic-silicon-modified sodium polyacrylate, solvent and filler, each material by mass percentage, organic-silicon-modified sodium polyacrylate 10-98%, solvent 0-90%, filler 0-30%.
Described organic-silicon-modified sodium polyacrylate at first by the silane coupling agent and the acrylic compounds copolyreaction that contain two keys, obtains organic-silicon-modified polyacrylic acid, obtains by adding the alkali neutralization then.The silane coupling agent that contains two keys is selected from one or more the mixture in vinyltrimethoxy silane, vinyltriethoxysilane, allyltrimethoxysilanis, allyltriethoxysilane, gamma-methyl allyl acyloxypropyl trimethoxysilane, gamma-methyl allyl acyloxypropyl triethoxyl silane or methacryloxypropyl three (isopropoxy) silane; Acrylic compounds has the structure of formula 1.

A kind of method for preparing anti-icing paint, carry out according to the following steps: organic-silicon-modified polyacrylate, solvent, pigment, flow agent, strengthening agent, fire retardant, antimildew disinfectant are added in the container, high-speed stirring, grinding forms.
Anti-icing paint of the present invention not only has good bonding force, higher heat conductivity to base material, its superficies have low surface tension, high hydrophobic, hate ice, can reduce the sticking power of water and ice to greatest extent, it is very easily come off, the more important thing is that can go out ion in severe environment ionization postpones adhering to of ice, thereby reach the purpose that prevents to coagulate ice and deicing.This method is simple on engineering, convenience is controlled, cost is lower, and result of use is good.Can be widely used in icing controls such as high-tension cable, iron tower, communication link and aircraft surface.
