Abstract
The invention relates to a clutch booster pump cylinder inner wall coating, characterized in that the coating technology comprises: degreasing the surface of the inner wall of a clutch booster pump cylinder by using derusting agent or hydrochloric acid, or by using surface coarsening treatment; cleaning and drying the surface treated inner wall; spraying or brushing the surface by using a paint with epoxy resin: curing agent being 100:15; sintering and drying for 0.5h at 120 DEG C, and placing at room temperature for cooling. The inner wall has excellent acid-alkali-resisting performance and wear-resisting performance, simultaneously reduces friction resistance, improves service life of the products with simple technology, easy operation, low investment.
Description
Technical background:
The present invention relates to a kind of clutch booster pump cylinder inner wall coating, be used for the clutch power-assisted pump cylinder.
Background technique:
The low quality problems in commercial car clutch power-assisted pump ubiquity working life of domestic automobile industry use at present, each automaker basic regulations aspect warranty after sale 1 year 30000 kilometers, show that according to investigation external product is minimum more than 200,000 kilometers working life.
The main pattern that domestic clutch power-assisted pump lost efficacy is that gas leakage and leakage of oil, especially product in use produce gas leakage and directly cause product function to lose efficacy accounting for more than 80% of total failare product.And the main cause that produces gas leakage is that the cylinder inner wall surface roughness is big, and cylinder rubber cup and inwall friction factor are big, in use the leather cup serious wear, simultaneously, owing to contain materials such as acid, alkali in the air, cylinder inner wall is perishable, quicken the wearing and tearing of leather cup simultaneously, caused product failure.
In addition, cylinder barrel cooperates a pair lubricating condition that is possessed to compare relatively poor with the motive sealing that rubber parts is formed, the limited lubricating grease of precoating is kept lubricated when only depending on the assembly assembling, along with the lubricated continuous consumption and the qualitative change of lubricating grease, it is more and more abominable that lubricating status will become, the coefficient of kinetic friction increases, thus quicken rubber parts wearing and tearing, cause hermetic seal to be lost efficacy.Cylinder inner wall is the metal finished surface, and roughness is R
Z0.6 ~ R
Z0.9 inwall is perishable, rubber is easy to wear.
Summary of the invention:
The object of the present invention is to provide a kind of clutch booster pump cylinder inner wall coating, cylinder inner wall coated one deck epoxy coating, make inwall have excellent acid-proof alkaline and wear-resisting property; Reduced surface friction drag simultaneously, friction factor is 0.04 ~ 0.07; The skimming wear of coating is 0.1 ~ 0.2mg/cm2 (pressing SUS23B); Serviceability temperature is-50 ℃ ~ 150 ℃, and in the working life of having improved product, improve more than 2 times the working life of product.
Technological scheme of the present invention is achieved in that clutch booster pump cylinder inner wall coating, it is characterized in that: coated technology is: the degrease that 1, at first clutch booster pump cylinder inner wall is carried out the surface, can adopt Rust preventative or hydrochloric acid etc., also can adopt surface coarsening to handle; 2, the clutch booster pump cylinder inner wall after the surface treatment is cleaned make its drying again; 3, host is QHO4-1 type epoxy resin, and curing agent is an amine curing agent, host: curing agent is 100:15.After the lacquer of adding curing agent stirs, and add an amount of X-7 epoxy lacquer diluent adjustment working viscosity, should place construction again in 15 ~ 30 minutes, use up in 8 hours and timely cleaning spray gun; 4, can spray or brush; 5, after sintering under 120 ℃ the condition is dried 0.5 hour, room temperature is placed up to cooling and is got final product; 6, the thickness of viscosity and spraying number of times may command paint film.
Good effect of the present invention is that the fatigue life test number of times of the clutch power-assisted pump assembly after inside coating is handled is brought up to 1,200,000 times by 500,000 times that do not have coating.Product improves more than 2 times working life; Technology is simple, easy to operate, little investment, only needs spray gun and pressurized air.
