Summary of the invention
The purpose of the present invention, it is simply that in order to provide a kind of ceramic metal anticorrosive paint and preparation method thereof, both environmental protection, warp
Ji, easy to produce and use, there is again the fabulous performance such as corrosion-resistant, stable, high temperature resistant, wear-resisting, pressure.
In order to achieve the above object, present invention employs techniques below scheme: a kind of ceramic metal anticorrosive paint, its component
And weight is as follows:
Epoxy resin 100;
Kaolin 1~10;
Nanometer aluminium powder 1~25;
Zircon English 1~8;
Nano aluminium oxide 1~20;
Carborundum 1~15;
Nanometer silica flour 1~20;
Porcelain powder 1~25;
Flake asbestos 1~10;
Graphite powder 1~8;
Color stuffing 1~20;
Bi Ke dispersant 0~6;
Bi Ke levelling agent 0~4;
Mixed organic solvents 1~25;
Other material 1~20.
Described mixed organic solvents is the mixture of acetone and toluene, and acetone is 3: 5 with the weight proportion of toluene.
Other described material includes Ludox or/and wax liquid.
The manufacture method of above-mentioned ceramic metal anticorrosive paint, comprises the following steps:
A, dispensing: with epoxy resin be 100 weight portions metering, the most accurately weigh Kaolin 1~10 weight portion, nano aluminum
Powder 1~25 weight portion, zircon English 1~8 weight portion, nano aluminium oxide 1~20 weight portion, carborundum 1~15 weight portion, nanometer stone
English powder 1~20 weight portion, porcelain powder 1~25 weight portion, flake asbestos 1~10 weight portion, graphite powder 1~8 weight portion, color stuffing 1~
20 weight portions, Bi Ke dispersant 0~6 weight portion, Bi Ke levelling agent 0~4 weight portion, mixed organic solvents 1~25 weight portion, its
Its material 1~20 weight portion;
B, at normal temperatures, uses nanometer by the Kaolin of dosage, zircon English, carborundum, porcelain powder, flake asbestos, graphite powder
Ultra fine, makes granularity reach 20-200nm, obtains nano-solid powder;
C, by step b gained nano-solid powder and the nanometer aluminium powder of dosage, nano aluminium oxide, nanometer silica flour, face
Filler and epoxy resin, Bi Ke dispersant, Bi Ke levelling agent, mixed organic solvents and the mixing of other material, and fully dispersed stir
Mix uniformly, obtain coating semi-finished product;
D, by step c gained coating semi-finished product through filter, canning sealing, obtain coating finished product.
Described mixed organic solvents is the mixture of acetone and toluene, and acetone is 3: 5 with the weight proportion of toluene.
Other described material includes Ludox or/and wax liquid.
The coating using ceramic metal anticorrosive paint of the present invention to be formed has fabulous wearability, corrosion resistance, impact resistance
Performance and stability, coating adhesion is strong, closely knit stable, can effectively completely cut off the erosion of acid, alkali, salt, sea water.Coating surface causes
Close, smooth, there are fabulous cathodic protection effect, fabulous antiseptic property, fast drying, adhesive force is strong, good impact-resistant abrasion-proof
Property, well gas cutting and weldability.Can be widely applied to petroleum pipeline, petroleum storage tank and chemical industry equipment, boats and ships, bridge
Beam, offshore platform and other steel construction etc..
Detailed description of the invention
Table 1 lists the formula (unit of weight for gram) of 10 embodiments, its manufacture method all: at normal temperatures, first
The Kaolin of dosage, zircon English, carborundum, porcelain powder, flake asbestos, graphite powder are ground in high-energy mill 50-100 minute, so
After after fine sieving, large-sized mixed powder is continued fine gtinding 50-80 minute again, make granularity reach 20-200nm.Again will
The solid powders such as the powder of twice grinding and nanometer aluminium powder, nano aluminium oxide, nanometer silica flour, color stuffing, with epoxy resin, finish
Liquid component mixing in the formula such as gram dispersant, Bi Ke levelling agent, mixed organic solvents and other material, and fully dispersed stir
Mix uniformly;Be then passed through filter, canning sealing forms.
Table 1
Ceramic metal anticorrosive paint of the present invention, without priming paint, can be not added with special finish paint and be used alone, the most directly
Spraying or brushing are in metal surface, before spary coating, need to carry out metal surface pretreatment and derusting by sandblasting St2.5 level with
On, then spray this coating thickness 150-220 μm coating, twice brushing can be divided, be spaced and be preferred for 6-12 hour.
By above-mentioned application operating procedure step, this paint coatings of thickness 180 μm ± 20 μm obtained is carried out anti-corrosive properties
Energy verification test, test result is as shown in table 2:
