Description
Technical field
The present invention relates to a kind of new anti-corrosion coating and preparation method thereof, more particularly, relate to a kind of Compound Outer Wall Heat-insulated Paint.
Background technology
Metallic corrosion meeting brings huge financial loss, causes number to waste with the iron and steel of hundred million tons.The iron and steel output of China, up to hundred million tons, wherein has 30% because corrosion has been wasted at present.On " 2009 development forum, fringe Hong Kong, Macao and Taiwan science technology and industry (corrosion prevention) ", brainstrust has also been inquired into the corrosion and protection of metallic substance to topic, propose, in order to prevent metallic corrosion, to reduce unnecessary financial loss simultaneously, must strengthen applying of anticorrosion technique.People have studied a lot of anti-corrosion methods for many years, and convenient, the most economic method is with protective system, metallic surface to be protected at present.
Traditional solvent-borne type protective system can discharge a large amount of VOC, and living environment and people healthy had to potential threat.Enhancing gradually along with people's environmental consciousness, Environmental Protection in China general bureau has just promulgated < < water-borne coatings environmental labelling product technical requirements > > in 2002, the quantity discharged of restriction VOC, to reduce the pollution of coating to environment, thereby water-based anticorrosive paint becomes the focus of falling over each other research.Water-based anticorrosive paint is mainly to take water as solvent and dispersion agent, compares production and transportation safer with solvent-borne type protective system, does not contain or contains a small amount of solvent, and VOC burst size is extremely low, is applicable to indoor and outdoor environment.At present, water-based anticorrosive paint has almost reached the performance of solvent-borne type protective system.Water-based anticorrosive paint kind is a lot, mainly contains epoxy, vinylformic acid, inorganic zinc silicate and polyurethane coating etc., wherein industrialized aqueous epoxy coating and aqueous inorganic zinc-enriched coating, the water soluble acrylic acid coating of mainly containing of success.
Water soluble acrylic acid protective system membrane formation mechanism is complicated, and sticking power is slightly short of compared with water-base epoxy; Aqueous inorganic zinc silicate anti-corrosive paint requires too high to processing base level, and easily forms high density zinc salt while not using finish paint; Property of Waterborne Polyurethane is fine, but cost is higher.
Polystyrene (PS) is a kind of unformed simple linear polymer, having the characteristics such as heat insulation, sound insulation, shockproof, waterproof, acid and alkali-resistance, have the advantages such as light weight is attractive in appearance concurrently, is one of most widely used plastics in the world, and mostly be disposable use, with the rear waste product that becomes.And useless PS chemical property is more stable, has the features such as anticorrosive, ageing-resistant, at occurring in nature, be difficult for aging rotting, be difficult to natural degradation and be degraded by microorganisms, not affine by physical environment.Landfill and burning are that people process two kinds of conventional methods of discarded PS now.Yet these two kinds of methods can cause the wasting of resources and serious environmental problem, consequent a large amount of " white garbage " become a great problem of current environment protection.Therefore using discarded PS to produce water-based anticorrosive paint, is a kind of mode of production that has environmental benefit.
Consider above-mentioned practical situation, those skilled in the art is being devoted to study a kind of novel water corrosion-resistant epoxy paint always, replace existing solvent-borne type protective system, and simultaneously need have good sticking power, lower cost and better simply preparation method.
Summary of the invention
For the deficiency existing in prior art, the invention provides a kind of novel environment friendly PS water-based anticorrosive paint.
