Abstract
The invention discloses a preparation and use method of a heating curing type wear-resistant composite ceramic coating. The method comprises the following steps: (1) heating 20 to 40 parts by weight of epoxy resin, 10 to 20 parts by weight of silicon carbide micro powder, 40 to 60 parts by weight of ceramsite, 6 to 12 parts by weight of aramid fiber powder, and 1 to 6 parts by weight of 1 to 3mm aramid chopped fiber to 55-60 DEG C; (2) agitating and mixing ceramsite and silicon carbide micro powder, and then adding aramid fiber powder to obtain a mixture A; (3) adding epoxy resin to the mixture A, and uniformly agitating to obtain a mixture B; (4) adding the aramid chopped fiber to the mixture B, uniformly agitating, cooling and then packing for later use; (5) coating or coating and then pressurizing with the quantity as required when in use, and heating at a temperature of 100 to 120 DEG C for 2-1 hour until reaching over 80% curing degree, thus obtaining the wear-resistant composite ceramic. The service life of the ceramic coating prepared by the method is more than three times that of the marketing wear-resistant ceramic coating; the ceramic coating is applied to wear-resistant protection treatment or repair of worn equipment, and the use scope of ceramic materials is expanded.
Description
Technical field
The present invention relates to a kind of preparation and application of heat curing antiwear composite ceramic coating.
Background technology
There are in the market many manufacturer production wearable ceramic coats, are used in the processing of equipment wear Protection or repair and reduce the consumption of material, but all not reaching desirable work-ing life.Ubiquity wear resistance, impact-resistance, erosion and is not reached the defect of service requirements.Major cause is: ceramic particle is connected with ceramic particle the power of amplexiforming and does not reach.In use ceramic particle constantly comes off under the washing away of medium, similarly is emery wheel drop, so wearing and tearing are very fast.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of heat curing antiwear composite ceramic coating.
The another one technical problem that the present invention will solve is to provide a kind of using method of heat curing antiwear composite ceramic coating.
For the preparation method of heat curing antiwear composite ceramic coating, the technical solution used in the present invention is: comprise the following steps:
(1) 20～40 parts of extracting epoxy resins, 10～20 parts of silicon carbide micro-powders, 40～60 parts of haydites, 6～12 parts, aramid fiber powder, 1～6 part of 1～3mm aramid fiber short fibre by weight, heats to 55 ℃～60 ℃;
(2) haydite and silicon carbide micro-powder are uniformly mixed, then add aramid fiber powder to obtain compound A;
(3) in compound A, add epoxy resin, stir and obtain compound B;
(4) aramid fiber short fibre is added in compound B, stir, wait after cooling and just can package spare.
As preferably, haydite specification is 20 order～480 orders.
For the using method of heat curing antiwear composite ceramic coating, the technical solution used in the present invention is: measure on demand with and smear or smear rear pressurization, at 100 ℃～120 ℃ temperature, heat 1～2 hour, reach more than 80% state of cure, form antiwear composite ceramic.
The invention has the beneficial effects as follows:
The employing response type environment resin of heating improves the strength of joint between ceramic particle and ceramic particle, and the aramid fiber short fibre simultaneously adding plays the effect of retouching solid ceramic particle between ceramic particle.This ceramic coating life-span is the more than 3 times of wearable ceramic coat life-span on market, and for wear-resisting protective treatment or equipment attrition reparation, the consumption that can be equipment reduction material is cost-saving, expands the use range of stupalith.
Embodiment
A preparation and application for heat curing antiwear composite ceramic coating, comprises the following steps:
(1) 30 parts of extracting epoxy resins, 20 parts of silicon carbide micro-powders, 30 parts of haydites, 10 parts, aramid fiber powder, 6 parts of 1～3mm aramid fiber short fibres by weight, heats to 55 ℃～60 ℃;
(2) haydite and silicon carbide micro-powder are uniformly mixed, then add aramid fiber powder to obtain compound A;
(3) in compound A, add epoxy resin, stir and obtain compound B;
(4) aramid fiber short fibre is added in compound B, stir, wait after cooling and just can package spare;
(5) while use, measure on demand and smear or smear rear pressurization, at 100 ℃～120 ℃ temperature, heat 2～1 hours, reach more than 80% state of cure, form antiwear composite ceramic.
Haydite specification range of choice is 20 order～480 orders.Specifically can select single specification to use, also can select 2-3 kind different size haydite to mix and use.
The present embodiment is applied to stock pump backplate or the protective layer of slag stock pump filtering bodies or tail-mineral pipeline.
Slag stock pump backplate protective shield has two kinds at present: a kind of is commercially available wearable ceramic coat, and work-ing life, workpiece approached rich chromium cast iron under low Scouring Condition, not competent under high Scouring Condition.Another kind is to paste one deck corundum ceramic piece as protective layer, the very good wear resistance showing at low Scouring Condition workpiece.But large at medium, under the large condition of scouring force, working, ceramic plate is frangible to come off.Use is restricted.
The present embodiment has solved the weak point of above-mentioned two kinds of stupaliths, is applied on slag stock pump or on pipeline, can increases exponentially work-ing life of virgin metal material.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present invention.
