Abstract
The invention provides an engine cylinder sleeve coating. The engine cylinder sleeve coating comprises, by weight, 40-50 parts of sodium bentonite, 90-100 parts of food help-filter reagent, 90-100 parts of quartz powder, 0.3-0.5 part of washing powder and 550-580 parts of water. The adhesiveness, smooth finish and strength of the engine cylinder sleeve coating are effectively improved by improving the burdening component matching of an ordinary engine cylinder sleeve coating and being in cooperation with a small amount of added washing powder serving as raw materials, and therefore the metallographic structure and mechanical performance of a cylinder sleeve are guaranteed, and the engine cylinder sleeve coating has the beneficial effects of being low in manufacturing cost and suitable for industrial production.
Description
Technical field
The present invention relates to cylinder sleeve manufacturing technology field, be specifically related to a kind of cylinder sleeve of engine coating.
Background technology
At present, because petroleum resources are in short supply and environmental pollution, improve automobile engine fuel efficiency, minimizing exhaust emissions has seemed and become more and more important.Two large assemblies of automobile engine are piston and cylinder sleeve, and wherein, cylinder sleeve requires that its material has the performances such as high temperature resistant, wear-resisting, withstand voltage and light weight.These performances of cylinder sleeve depend on metallographic structure and the mechanical performance of cylinder sleeve, and the coating of metal pattern has a great impact the metallographic structure of cylinder sleeve and mechanical performance, in prior art, for the coating of spraying mold, uniformity and intensity are all difficult to ensure that cylinder sleeve can obtain good metallographic structure and mechanical performance, its tack of coating of the present invention, intensity, fineness and manufacturing cost, all have larger room for improvement.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of tack and fineness is good, intensity is high, the cylinder sleeve of engine coating of low cost of manufacture.
A kind of cylinder sleeve of engine coating provided by the invention, comprises the raw material of following weight portion: sodium bentonite 40-50 part, food filter aid 90-100 part, silica flour 90-100 part, washing powder 0.3-0.5 part, water 550-580 part.
Further describe as to technique scheme:
Described food filter aid is super-cell.
Further describe as to technique scheme:
The order number of described silica flour is 320 orders.
The present invention is by improving the furnish component proportioning of common engine cylinder sleeve coating, coordinate a small amount of detergent raw material added, effectively raise the tack of cylinder sleeve of engine coating, fineness and intensity, thus ensure that metallographic structure and the mechanical performance of cylinder sleeve, and there is low cost of manufacture, adapt to the advantage of suitability for industrialized production.
Detailed description of the invention
Below in conjunction with specific embodiment, invention is described in further detail.
A kind of cylinder sleeve of engine coating, comprises the raw material of following weight portion: sodium bentonite 40-50 part, food filter aid 90-100 part, silica flour 90-100 part, washing powder 0.3-0.5 part, water 550-580 part.
Wherein, sodium bentonite ensures suspension and the intensity of coating as suspending agent and bonding agent.
Wherein, silica flour is as the fire resistance of the aggregate increase coating of refractory body.
Wherein, food-grade filter aid Main Ingredients and Appearance is diatomite, is filled into the compactness improving coating between silica flour, and the fineness of such blank surface is improved significantly, utilize diatomaceous hollow to increase the heat-insulating property of coating, ensure the stability of foundry goods metallographic structure.
Wherein, washing powder increases the slip of coating, during spraying, coating more uniformly can be distributed in mould inner surface, coating layer thickness after dry evenly, washing powder has foam performance can form cavity tiny one by one between coating and mould, and after cast, namely this cavity is formed uniform protruding one by one at cast(ing) surface.Bond strength between this kind of protruding increase cylinder sleeve and aluminium alloy cylinder and heat conductivility, can reduce mechanically deform amount and the heat distortion amount of cylinder sleeve of engine better, thus improve engine performance and emissions reduction.
