Abstract
The utility model discloses a wear-resisting composite board, including the base member layer of lower floor and covering the wearing layer on the base member layer, its characterized in that: the wear-resistant layer is covered with a first corrosion-resistant protective layer, and the first corrosion-resistant protective layer is covered with a second corrosion-resistant protective layer. The utility model discloses an adopt double-deck protective layer's structure, make whole composite sheet have stronger corrosion resistance and wearability. Greatly prolongs the service life of the composite board.
Description
Technical field
The utility model relates to architectural decoration material field, relates in particular to a kind of wear-resistant composite board with strong antiseptic property.
Background technology
Wear-resistant composite board, general title is a wear-resisting steel plate, is a kind of high abrasion composite material, and it adopts automatic dull and stereotyped welding equipment, and built-up welding forms hypereutectic high-chromium alloy wear-resisting layer on steel plate, becomes built-up welding high-chromium alloy wear-resisting steel plate.Carbide is fibrous distribution in its metallographic structure, and machine direction is vertical with the surface.Case hardness is very high, in certain temperature range, also the post-curing phenomenon can occur, further improves anti-wear performance; It has the characteristic of the multiple dielectric material of high rigidity and high tenacity; Shock resistance is good, and in use wearing layer can not come off, and it also can cut; Bending, processing such as welding.The wearing layer of Wear-Resistant Compound Steel Plate is main with chromium mainly; Also have other compositions such as manganese, molybdenum simultaneously, the alloy carbide of formation at high temperature has very strong stability, continues the hardness that keeps higher; Also has good antioxygenic property simultaneously, normal fully use the below 500 ℃.
Wear-resistant composite board mainly has following four big characteristics: one, high wear resistance, wear test show that the abrasion resistance of wear-resistant composite board is higher more than 20 times than mild steel, and be higher more than 5 times than stainless steel, potassium steel.Two, high impact resistance, owing to adopt the mild steel substrate, wear-resistant composite board has very high shock resistance, has demonstrated fully the not only wear-resisting but also shock proof advantage of composite material.Three, processing characteristics easily, the hardfacing composite steel plate can be out of shape, weld, and can be processed into various wear-resistant parts as general steel plate easily.Four, high performance price ratio though use the surperficial cost of hardfacing composite plate to improve, is taken all factors into consideration the application life, maintenance cost, shutdown loss of parts etc., and its ratio of performance to price exceeds the about 2-4 of common material times.Because material uses rationally, the hardfacing composite plate is than equivalent material manual build up welding price low 50%.At present, wear-resistant composite board mainly be with wear-resisting be main, its wearing layer can reach wear-resisting requirement basically.But its antiseptic property is relatively poor, because the continuous progress of society, environment pollution is serious relatively than before.Long-term acid rain invasion and attack can be accelerated the corrosion of wear-resistant composite board, if wearing layer has been eroded, will have a strong impact on the normal use of wear-resistant composite board.
Publication number is CN201769407U, and it is characterized in that: comprise wearing layer and stainless steel basic unit, described wearing layer and basic unit were as a whole for the Chinese patent document of 2011.03.23 discloses a kind of wear-resisting accurate clad steel slide plate in open day.This patent documentation when increasing abrasion resistance, also has some improvement to corrosion resistance through increasing stainless steel basic unit, mainly shows on the sour corrosion, like acid rain.But but resistance is lower to the corrosion of alkaline medium in stainless steel basic unit.So this patent documentation does not fundamentally solve the problem of corrosion resistance.
Summary of the invention
The utility model is intended to the more weak defective of above-mentioned prior art corrosion resistance a kind of wear-resistant composite board that has than strong corrosion resistant property is provided.The utlity model has characteristics than strong corrosion resistant property and abrasion resistance.
In order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is:
Wear-resistant composite board comprises the base layer of lower floor and is covering the wearing layer on base layer that it is characterized in that: covering on the said wearing layer has the first corrosion-resistant topping, and covering on the said first corrosion-resistant topping has the second corrosion-resistant topping.
The said first corrosion-resistant topping is the alumin(i)um zinc alloy layer.
The thickness of the said first corrosion-resistant topping is 5-10mm.
The said second corrosion-resistant topping is a chrome molybdenum cast steel layer.
The thickness of the said second corrosion-resistant topping is 10-15mm.
During use, because the superiors are chrome molybdenum cast steel layers, under the condition of high temperature and corrosion, metallic matrix is difficult for embrittlement; Can avoid causing damage in bending and the tensile strain; Lower floor is provided with the alumin(i)um zinc alloy layer at chrome molybdenum cast steel layer, and the alumin(i)um zinc alloy layer can be protected metallic matrix equally, and it is acidproof, alkaline resistance properties is stronger.Through adopting the structure of double shielding layer, make whole composite plate have stronger corrosion resistance and abrasion resistance.Prolonged the application life of composite plate greatly.
The beneficial effect of the utility model mainly shows the following aspects:
One, through on base layer, covering chrome molybdenum cast steel layer, under the condition of high temperature and corrosion, metallic matrix is difficult for embrittlement; Can avoid causing damage in bending and the tensile strain.
Two, in chrome molybdenum cast steel layer lower floor the alumin(i)um zinc alloy layer is set, the alumin(i)um zinc alloy layer can be protected metallic matrix equally, and it is acidproof, alkaline resistance properties is stronger.
Three, through adopting the structure of double shielding layer, make whole composite plate have stronger corrosion resistance and abrasion resistance.Prolonged the application life of composite plate greatly.
Four, through limiting the thickness of the first corrosion-resistant topping and the second corrosion-resistant topping, make whole composite plate structure more reasonable, can effectively bring into play the composite plate decay resistance.
