Description
Technical field
The present invention relates to the epoxy coating technical field, relate in particular to a kind of epoxy potable water tank paint and preparation method.
Background technology
Modern material progress be unable to do without coating everywhere, invariably protects with coating from boats and ships, bridge, harbour, port facilities to daily living articles such as toys and decorates.
Potable water tank paint refers to be applied to boats and ships drinking water tank cabinet internal surface, has the coating that antiseptic property also can guarantee edible water quality.Mostly contain benzene kind solvent in the existing potable water tank paint product, environment and workmen are had certain harm.
At present, the used coating of boats and ships drinking water tank adopts pure epoxy coating substantially, and its kind comprises solvent epoxy coatings, high solid epoxy coating and solventless epoxy coating.Because boats and ships drinking water tank cabin is narrow and small, air is difficult to circulation, thereby organic solvent volatilization content and the toxicity restriction of coating had higher requirement.
CN1605607A relates to a kind of container inner wall non-toxic coatings take Resins, epoxy as base-material, and its composition comprises: Resins, epoxy 100 weight parts; Polyamide curing agent 30～70 weight parts; Color stuffing 20～120 weight parts; Alcoholic solvent 20～60 weight parts; Thickening material 1～10 weight part.It is in 0.20～0.45 one or more that described Resins, epoxy is selected from epoxy equivalent (weight).Polyamide curing agent is formed by dimerization oleic acid and polyamine condensation.
CN102010646A discloses a kind of low-temperature quick-dry non-solvent epoxy potable water tank paint and preparation method, form A by Resins, epoxy, reactive thinner, dispersion agent, silane coupling agent, thixotroping auxiliary agent, titanium dioxide, talcum powder, defoamer, curing agent and catalyzer, B two components; Mix according to the proportioning of weight ratio A:B=7.5:18.5 in use, the mixing viscosity under 10～15 ℃ of conditions of low temperature is 3000～5000mPa.s, and operable time is 1～2 hour, and the semi-harden time is 6～8 hours, and setting time is 20～24 hours.
Solventless epoxy coating viscosity is larger, and particularly in the winter time during low-temperature construction, viscosity sharply increases, and therefore must take other measures to reduce dope viscosity, just can make the coating normal construction.As: in use coating is left in indoor as far as possible, at the scene coating is placed in advance and keeps temperature in the freight container, make the temperature of coating itself be not less than 15 ℃ as far as possible, reduce viscosity with the temperature that improves coating, reach the requirement that can spray, and the pressure of suitable raising paint pump is tried one's best and is shortened the length of the leather hose that sprays paint, so that coating can spray normally.
In addition, general solventless epoxy coating is when 70 ℃ of left and right sides of low temperature, and speed of response is slow, and setting time is long, is difficult to adapt to actual coating process requirement.
Existing solvent epoxy coatings is except having certain toxicity and security hidden danger, and to having relatively high expectations of substrate surface treatment, coating is much not enough in the existence of the aspects such as elasticity, sticking power, workability, and over-all properties is excellent not.Existing epoxy potable water tank paint, salt spray resistance is generally at 600h, and this product reaches 1000h; In addition, with traditional epoxy potable water tank paint comparison, this product has increased salt water resistance performance index.
Summary of the invention

Applicant's statement, the person of ordinary skill in the field is on the basis of above-described embodiment, concrete content point value with above-described embodiment component, combined with the technical scheme of summary of the invention part, thereby the new numerical range that produces, also be one of record scope of the present invention, the application is no longer enumerated these numerical ranges for making specification sheets simple and clear.
Applicant's statement, the present invention illustrates preparation process of the present invention by above-described embodiment, but the present invention is not limited to above-mentioned preparation process, does not mean that namely the present invention must rely on above-mentioned preparation process and could implement.The person of ordinary skill in the field should understand, any improvement in the present invention to the interpolation of the equivalence replacement of the selected raw material of the present invention and ancillary component, the selection of concrete mode etc., all drops within protection scope of the present invention and the open scope.
It is as shown in table 1 that the embodiment of the invention 1～8 described coating is carried out the properties test result:
The performance test results of each embodiment product of table 1
Control first component viscosity main purpose has two: one, and the production process medium viscosity is too thick, increases the difficulty of filtering, and the 2nd, too thick being unfavorable for constructs.The viscosity of component B is fixing substantially, because be the combination packaging of solidifying agent and solvent.Control the viscosity of first component, equaled to control the viscosity of product.
As can be seen from Table 1: 1, traditional drinking water tank lacquer, its solvent forms (ratio between the three is 75:20:5) by dimethylbenzene, propyl carbinol and pimelinketone, and product of the present invention has substituted dimethylbenzene and pimelinketone with butanone, has reduced product toxicity; 2, the product innovation drying property was brought up to 2 hour in 4 hours than the increasing of traditional product by surface drying, did solid work by 24 hours and brought up to 12 hours; 3, salt spray resistance was brought up to 1000 hours by 600 hours; 4, increased salt water resistance performance index.
Aerosil itself also has good thickening properties.Increased thickening material in the present invention's prescription, so, the ratio of aerosil can be selected between 0.5～1.2%, can slightly reduce than original formulation (0.8%).
Component B viscosity and density are fixed, and have controlled first component density, have just controlled product density.
To sum up, epoxy potable water tank paint of the present invention has the following advantages:
1) low prepared surface requires: can construct by insufficient or moist steel surface in rust cleaning; Can make priming paint that the processing requirements on steel substrate surface is reduced to ISO St2 level even following degree from common ISO Sa2～2.5 grades and St3 level, thereby greatly reduce the rust cleaning workload before the application.
2) substitute benzene kind solvent with ketone and alcoholic solvent, reduced product toxicity.
3) paint film good springiness is to metal with nonmetal very strong cohesive strength arranged.
4) good weatherability, paint film is difficult for loss of gloss, efflorescence during outdoor.
5) have good workability the morbid state such as the difficult skinning that produces of paint film, whiting.
6) one build of Airless spraying can reach more than the 125 μ m, reduced the application number of times, reduced the harm of coating to human body, improved operator's application security.
7) reasonable ratio of two components makes paint film that good hardness, snappiness, water tolerance and chemical-resistant be arranged.
