Description
Technical field
The invention belongs to gluing wear-resistant material technical fields, and in particular to a kind of normal-temperature high-strength degree gluing wear-resistant material and its
Preparation method.
Background technique
With the development of economy and society, there is a growing awareness that reduce machinery equipment, workpiece abrasion importance,
Wear resistance adhesive coating is at home and abroad all widely used and develops.Wear resistance adhesive coating refers to thermosetting polymer glue
Stick matrix and hard, wear-resistant particle (reinforced phase) are mixed in certain technique and ratio, coated on the workpiece surface cleared up to obtain
A kind of sufacing of wear-resisting property needed for obtaining.This wear-resistant coating coated technique is simple, and low in cost, cure shrinkage is small, can
Except the reparation of preset coating corrosion-resistant for piece surface, anti abrasive and component corrosion wear surface, it is also widely used in and repairs
Mend the various defects such as crackle, scuffing, dimension overproof and casting flaw etc. on workpiece.Epoxy resin-matrix wear-resisting composite coating
It is to use epoxy resin as adhesive, adds the abrasion resistant particles such as silicon carbide, aluminium oxide as filler, react hard with amine curing agent
It is increasingly extensive applied to workpiece (such as turbine blade, mud of the work under slurry erosion wear operating condition to change obtained material
Pump, ore separators component etc.) surface, the repairing as erosion resistance protective coating, and for corrosion, wear face is since it has
Good erosion-wear-resisting performance, and coated technique is simple, low in cost, no heat affected area and deformation etc., thus have wide
General application prospect.
Tradition research thinks that the adhesive component of epoxy resin wear-resisting adhesive coating has semi plastic, and adhesive component is in abrasive material
Impact under can generate plastic deformation lip, simultaneously because the plasticity of adhesive component is not fine, therefore, when reaching certain deformation
After amount, adhesive component will be cracked, and be peeled off in a manner of sheet, bulk etc..In adhesive component in conjunction with hard, wear-resistant particle
Afterwards, whole rate of depreciation is rendered as two stages, and the first stage is the Fast Wearing stage, and second stage is stable abrasion at a slow speed
Stage, because in the first stage, hard, wear-resistant particle and erosion media contact face are smaller, the contact of adhesive component and erosion medium
Face is larger, and the abrasion resistance properties of adhesive component are poor, and therefore, when the first stage, rate of depreciation is very fast；When second stage, due to sudden and violent
The more adhesive component of dew is fallen by erosion, so that hard, wear-resistant particle becomes washed out main component, hard, wear-resistant
The wear-resisting property of particle is preferable, and therefore, the rate of depreciation slow and steady of second stage is fixed, still, due in the first stage, gluing group
Divide by a large amount of erosions, therefore, in second stage, although the rate that hard, wear-resistant particle is worn is smaller, lack gluing
Component is adhesively fixed, it is thus possible to can there is a phenomenon where massive materials directly to peel off, therefore, the wear-resisting glue of conventional epoxies
The abrasion mechanism of adhesive coating layer is complex, and wear-resisting property is also in urgent need to be improved.
By retrieval, the patent of invention of application number CN201110151662.5 discloses a kind of epoxy resin wear resistance adhesive painting
Layer and preparation method.The epoxy resin wear-resisting adhesive coating is grouped as by two groups of A, B, wherein component A by following parts by weight group
It is grouped as: 80-100 parts of bisphenol A type epoxy resin, 10-30 parts of toughener, 15-30 parts of diluent, 3-6 parts of fiber, silica flour
15-30 parts, 30-50 parts of silicon carbide, 5-15 parts of zinc oxide, 1-10 parts of gas-phase silica, 200-400 parts of ceramic particle, B component by

Part, 1-5 parts of fiber, 10-30 parts of silica flour, 20-30 parts of silicon carbide, 5-10 parts of zinc oxide, 1-10 parts of gas-phase silica, ceramics
200-300 parts of grain, the weight ratio of two component of A, B are 4:1.The present invention is by homemade CTBN modified epoxy as toughener
Toughening modifying is carried out to epoxy wear resistance adhesive coating, improves the adhesion strength to substrate, improves the stress state between coating and matrix,
Ceramic particle and the colloid for being coated on its surface are made by addition different weight number and varigrained ceramic particle simultaneously
The rigid spheres constituted can be uniformly filled in the gap between bulky grain, so that particle is arranged in most intensive mode,
The intensity and wearability of wear-resistant coating glue are improved, while having very strong operability in terms of construction, thixotropy is excellent, can be applied
Facade does not trickle, and the operating time is long, is applicable to large area coating, and normal temperature cure is coated workpiece afterwards for 24 hours and can put into operation.
But according to its narration, different weight number and varigrained ceramic particle are added in order that making ceramic particle and being coated on
The rigid spheres that the colloid on its surface is constituted can be uniformly filled in the gap between bulky grain.The thinking makes between bulky grain
Gap filled uniformly with, on the one hand, do not provide specific operating method, on the other hand, since it is most close from space
From the point of view of the problem of, but there is only a contact planes in fact, wear resistance adhesive coating is with erosion medium, from the angle in space
Degree considers that accumulation compactness can make cost be difficult to control, and effect is also correspondingly got half the result with twice the effort.
Application No. is the patent of invention of CN201410667378.7 disclose a kind of heat resistant and wear resistant Epoxy Bonding Coating and
