Abstract
Anti-corrosion paint consists of two components, the component A consists of modified epoxy resin as main part, gaseous silica as additive and stuffing including titanium pigment, mica powder, blanc fixe and barium sulfate; and the component B contains modified polyamide as main part and solvent ethy acetate and butyl alcohol using non-toxic additive and stuffing makes the paint form non-toxic film. Gaseous slica with excellent thixotropy and densifying effect makes it possible to form leveled dry film as thick as 200 microns in once painting and the film has certain antimicrobial effect.
Description
What the present invention relates to is a kind of protective system, is mainly used in drinking water pipeline, the container anticorrosion.
As everyone knows, the inner wall anti-corrosive of tap water transmission ﹠ distribution equipment (comprise large-scale former water quote engineering pipeline), naval vessel, ocean drinking water tank, used coating except that require must be nontoxic, also requiring to film to have certain thickness, otherwise does not just reach the rot-resistant effect.
Former water is quoted engineering pipeline and mostly is cement pipe, and its inwall is general more coarse, has many pores.These pores provide favourable condition for concealing of microorganism, former larva and bacterium in the water.Microorganism, former larva and bacterium invade growth in the pore of cement tube wall, breeding, make tube wall form microbial film, cause pipeline microbial contamination, cause the pollution of water quality then.Therefore, tap water (comprising former water) pipeline, container have not been simple anticorrosion problem, and anticorrosion relatively problem prevents that the microbial contamination of water quality from seeming even more important.And traditional latex cement mortar lining technology can't satisfy the double requirements of anticorrosion, the anti-soil of drinking water pipeline, container.Pipeline, container inner wall that to the substitute is with high performance hygienic safety type protective system be core are coated with the lining technology.
Chinese patent 95117902.0 discloses a kind of " thick-film type one-pass film-forming anticorrosive paint ", be in containing the first component of Resins, epoxy, to add a certain amount of long-chain fat hydrocarbon, adopt toluene, butanols to make solvent,, only be applicable to the anticorrosion of oilfield sewage pipe, jar owing to contain toluene in the solvent that uses.Chinese patent 89105340.9 discloses a kind of " non-poison and non-solvate epoxy paint ", with Resins, epoxy is main raw material (molecular weight is below 900), add amine curing agent, pigment (Fe2O3), softening agent (phthalic acid lipid), promoting agent (phenylcarbinol), mix the back mechanically spraying with technology by a certain percentage, be used for the anticorrosion of food-drink processing jar, groove.Shortcoming is in actual use, and coating is to constructing operation conditional request harshness, and spraying equipment cleans difficulty, is not suitable for the squeezing and coating of main equipment.
The objective of the invention is interior anticorrosion at drinking water pipeline, container, solve the double requirements of antimicrobial pollution simultaneously and proposed impregnating material in a kind of drinking water pipeline, container of novel i.e. safety health.
The present invention divides A, B two components, the A component is based on modified epoxy, add auxiliary agent (aerosil) and filler (titanium dioxide, mica powder, ground barium sulfate, barium sulfate), in the B component with modified polyamide for leading and containing solvent vinyl acetic monomer and butanols, because auxiliary agent and the filler selected for use are nontoxic, make the dry film nontoxicity that forms behind the paint spay-coating.Aerosil has fabulous thixotropy and thickening power, has the characteristic of one-pass film-forming, and once spraying can form thickness and reaches the above nontoxic dry film of 200 μ m, and smooth and sagging not, and has certain anti-microbial effect.In the drinking water pipeline, container after filming, formed dry film has stopped up the pore of tube wall, has stoped the intrusion of microbial spore and bacterium in the water, has eliminated its place of perching and breeding.Improve the slickness of tube wall simultaneously, reduced the coefficient of friction resistance, strengthened flow velocity, made microorganism in the water, former larva and bacterium be difficult on tube wall, adhere to and accumulate, avoided the formation of microbial film on the tube wall then.
The preparation of drinking water pipeline, container inner side anticorrosion coating:
The A component: earlier modified epoxy is deployed into resin liquid by proportioning, successively various auxiliary agents and filler is added in the resin liquid in proportion, normal temperature is ground to≤80 μ m after stirring down, put in the mediation still, add solvent again, control viscosity is at 30～50 pools, and the qualified after-filtration of viscosity is packed.
B component: press to mix under the formula rate normal temperature and stir the back packing.
During use, in the A component: it is right that B component=100: 15 ratio is mixed, and once sprays dry film and can reach more than the 200 μ m.
Drinking water pipeline, container inner side anticorrosion coating have following characteristics:
1, extremely strong sticking power.Metal, concrete structure face all there is good cohesive force.
2, good mechanical and physical performance, snappiness is good, and is excellent in cushion effect.
3, excellent chemical stability energy and water-fast, oil resistant, ageing resistance.
4, paint film is nontoxic behind the dried coating film.Acute mouthful of toxicity test belongs to nontoxic level.Mouse bone marrow cells chromosomal aberration test, Salmonella reversion test result are all negative.Chemical Analysis: paint film is pressed GB/T17219-98 " Drinking Water equipment and protective material safety standards " and after 30～90 days, the soak solution assay is all met the regulation of GB/5749-85 " drinking water sanitary standard " through the water logging bubble.Clear water soaked 1000 hours, and the check clear water does not have exudate.Therefore, the coating that uses the present invention's production can not pollute water quality as being coated with impregnating material in drinking water pipeline, the container.
For guaranteeing the realization of above-mentioned purpose, raw materials used before use all through check one by one, guaranteeing not conform to has heavy metals such as aluminium, lead, chromium, cadmium.The preparation container all uses specific equipment.
