[0014] The invention provides a method for preparing a clutch pump piston, comprising:

[0015] 1) breaking the sweet potato, then placing it in the yeast solution for fermentation, and then filtering to take the filter cake to obtain the modifier;

[0016] 2) calcining bentonite and iron slag, and then activating in the presence of X-rays to obtain an activator;

[0017] 3) Polycarbonate, ethylene-vinyl acetate copolymer, cellulose propionate, vinyl propionate, n-butanol, nano-magnesium oxide, rare earth oxide, potassium titanate whisker, m-methylaniline, aniline methyl Triethoxysilane, pyrimidine, p-benzoquinone, simethicone, modifier and activator are mixed, cooled and formed, and granulated to obtain the clutch pump piston material;

[0018] 4) The clutch lever material is melted at 195-205° C., and then extruded to obtain the clutch pump piston.

[0019] In step 1) of the present invention, the specific conditions of fermentation can be selected in a wide range, but in ...

Embodiment 1

[0030] 1) The sweet potato is crushed, then fermented in yeast solution (concentration: 26% by weight) at 50°C for 27 hours, and then the filter cake is filtered to obtain the modifier; wherein, the weight ratio of sweet potato to yeast solution is 100:275 ;

[0031] 2) Mix bentonite and iron slag at a weight ratio of 100:20 and calcinate at 450°C for 5h, then put them in the presence of X-rays (wavelength 4nm), and activate at 90°C for 50min to produce get activator;

[0032] 3) Polycarbonate (weight-average molecular weight is 6000), ethylene-vinyl acetate copolymer (weight-average molecular weight is 10000), cellulose propionate, vinyl propionate, n-butanol, nano magnesium oxide (particle size is 10nm ), rare earth oxides (cerium oxide), potassium titanate whiskers, m-methylaniline, anilinomethyltriethoxysilane, pyrimidine, p-benzoquinone, simethicone, modifiers and activators according to 100: The weight ratio of 75:4.5:18:30:15:10:5:30:25:10:17:6:35:26 was mixed at 228°...

Embodiment 2

[0035] 1) The sweet potato is crushed, then placed in a yeast solution (22% by weight) at 45°C for fermentation for 20 hours, and then the filter cake is filtered to obtain a modifier; wherein the weight ratio of sweet potato to yeast solution is 100:200 ;

[0036] 2) Mix bentonite and iron slag according to the weight ratio of 100:14 and calcinate at 440°C for 4h, then put them in the presence of X-rays (wavelength: 3nm), and activate them at 85°C for 40min to produce get activator;

[0037] 3) Polycarbonate (weight-average molecular weight is 4500), ethylene-vinyl acetate copolymer (weight-average molecular weight is 8000), cellulose propionate, vinyl propionate, n-butanol, nano magnesium oxide (particle diameter is 8nm ), rare earth oxides (europium oxide), potassium titanate whiskers, m-methylaniline, anilinomethyltriethoxysilane, pyrimidine, p-benzoquinone, simethicone, modifiers and activators according to 100: The weight ratio of 72:4:16:25:11:8:3:24:17:6:14:2:33:22 w...

Abstract

The invention discloses a clutch pump piston and a preparation method thereof. The preparation method comprises the steps of 1) smashing sweet potato, putting the smashed sweet potato into a yeast solution for fermentation, then filtering and taking a filter cake, so as to obtain a modifier; 2) calcining bentonite and iron-ore slag, then putting the calcined bentonite and iron-ore slag in X-rays for activating treatment, so as to obtain an activator; 3) mixing makrolon, an ethylene-vinyl acetate copolymer, cellulose propionate, vinyl propionate, n-butyl alcohol, nanometer magnesia, a rare-earth oxide, a potassium titanate whisker, m-toluidine, anilmomethyl triethoxy silane, pyrimidine, p-benzoquinone, simethicone and the modifier with the activator, cooling, molding and pelleting to obtain a clutch pump piston material; 4) melting the clutch pump pulling bar material at 195 to 205 DEG C, and then the clutch pump piston is obtained by extrusion molding. The clutch pump piston prepared by the method has excellent mechanical property.

Description

technical field [0001] The invention relates to a clutch pump piston, in particular to a clutch pump piston and a preparation method thereof. Background technique [0002] The clutch, commonly known as Jilizi, is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed on the rear plane of the flywheel with screws, and the engine power of the car or other power machinery is transmitted to the axle in the form of a switch. installation. During the driving process of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the transmission, so as to cut off or transmit the power input from the engine to the transmission. [0003] The clutch pump piston is one of the important components in the clutch. Since the clutch pump piston works continuously during the use of the clutch, the clutch pump piston is easily broken. Contents of the invention [0004] The objec...
