Abstract
The invention discloses a waterproof corrosion-resistant coating for inner walls of a water conveying pipeline and a container. The coating comprises the following components in percentage by weight: 50 to 60 percent of macromolecular epoxy resin polymer, 10 to 12 percent of polyamide-alicyclic amine hardening agent, 15 to 10 percent of edible titanium white, 16 to 9 percent of mixed solvent and 9 percent of edible talcpowder, wherein the mixed solvent is dimethylbenzene, butyl acetate and ethanol; and the ratio of the dimethylbenzene to the butyl acetate to the ethanol is 4:2:2. Compared with the conventional like products, the coating obviously improves the bond strength on concrete and steel structures, has higher permeability on the concrete and the steel structures, is convenient to construct and operate, has wide material sources and readily available materials, can be applied to resisting corrosion on the inner surfaces of various original water pipelines of tap water, water purifying pipelines, drinking water pipelines, domestic water conveying pipelines, concrete water storage ponds and concrete water storage tanks, has wide application space, and obviously prolongs service life and improves hygienic property of the water conveying pipelines and the water storage tanks.
Description
Technical field
The present invention relates to a kind of coating, specifically be the water-fast protective system of a kind of water pipe and container inner wall, this coating is applicable in the tap water raw water pipeline, water purification pipeline, Drinking Water pipeline, domestic water water pipe, the protection against corrosion of concrete tank, concrete water tank internal surface.
Background technology
At present, at tap water water pipe corrosion-resistant field, the water pipe inwall uses the sand-cement slurry swabbing to handle mostly, the cohesive strength of its screed and steel pipe is very poor, very easily cause the swabbing pull-up to fall, because the cement swabbing is alkalescence, can produce certain pollution simultaneously water body.Same, as the concrete secondary water tank on the tier building, after for some time used, fouling and non-easy cleaning can appear in internal surface, cause the secondary pollution to water body.And concrete sump is without rotproofing, and silicate and phosphoric acid salt that concrete itself discharges can pollute water body.In addition, existing water supply pipe coating that inwall uses, cohesive strength is low, easily comes off after the use, causes the pollution to water body.
Summary of the invention
Technical problem to be solved by this invention provides a kind of water pipe and the water-fast protective system of container inner wall, this coating is when satisfying long-term water resistance, steel pipe and concrete are had good cohesive strength, and this material meets paddle the product hygienic safety performance and the requirement of national health administrative department regulation fully.
A kind of water pipe of the present invention and the water-fast protective system of container inner wall, its component and weight proportion are respectively: high molecular expoxy resin polymkeric substance 50%-60%, polymeric amide-aliphatic cyclic amine stiffening agent 10%-12%, food grade titanium dioxide 15%-10%, mixed solvent 16%-9%, food grade talcum powder 9%.
The component of above-mentioned mixed solvent and weight proportion are dimethylbenzene:: N-BUTYL ACETATE: ethanol=4:2:2.
Product of the present invention is owing to used the resin system of macromolecule epoxy resin polymkeric substance and plant oil modified amine polymer, wherein, the molecular structure of Resins, epoxy is containing active epoxide group in the molecular chain for its feature, and epoxide group can be positioned at the end, centre of molecular chain or structure circlewise; Owing to contain active epoxide group in the molecular structure, make them form insoluble, infusible superpolymer with polytype solidifying agent generation crosslinking reaction with tridimensional network.Because these characteristics, guaranteed the sticking power of product of the present invention to concrete, metal, synthetic materials etc., coating itself is very corrosion-resistant, mechanical property is good, has wear-resisting, shock-resistant, organic solvent-resistant, heat-resisting, water-fast, the characteristic such as nontoxic of filming.
Product of the present invention is compared with present like product, cohesive strength to concrete, steel construction obviously improves, perviousness to concrete and steel construction is better, be convenient to constructing operation, material source extensively, be easy to get, can be in various tap water raw water pipelines, water purification pipeline, Drinking Water pipeline, domestic water water pipe, concrete tank, the protection against corrosion of concrete water tank internal surface use, and possesses wide application space, obviously promotes the work-ing life of water pipe.
Product of the present invention has following characteristics after tested:
1, sticking power (drawing lattice 1mm): 0 grade;
2, cohesive strength (drawing back method): 3.0MPa;
3, snappiness: 1mm;
4, water tolerance: 30d no change;
5, safety and sanitation performance: meet the GB5749-2006 drinking water sanitary standard;
6, safety and sanitation performance: meet GB/T5750.1～5750.13-2006 drinking water standard method of inspection;
2001] requirement of No. 161 literary compositions " Drinking Water transmission ﹠ distribution wetting system and protective material hygienic safety value disciplines ".
