Abstract

The invention discloses a preparation method of a stretch-proof composite belt. The method comprises the following steps: taking 20-30 parts of palletized carbon black, adding 100-150 parts of water, sequentially adding 10-12 parts of sodium dodecyl benzene sulfonate, 3-5 parts of zinc oxide, 3-5 parts of stearic acid, 7-9 parts of sulphur and 4-6 parts of an accelerant, putting the mixture obtained from the former step into a ball mill, wherein the ball-milling speed is 360-380r / min; and the time is 120 minutes; reversing at each interval of 15-18 minutes, and carrying out ultrasonic treatment for 2-3 hours after ball milling; taking 60-70 parts of natural latex, adding 500-600 parts of water, stirring the natural latex for 3-4 hours and drying the mixture for 5-6 hours; adding 1-2 parts of titanium dioxide, 3-8 parts of benzoyl peroxide, 2-6 parts of super-fine magnesium hydroxide, 1-5 parts of zinc borate and 300-400 parts of water, and stirring the raw materials for 1-2 hours; adding 100-200 parts of an styrene adhesive, heating the styrene adhesive at 70-80 DEG C for 30 minutes, and cooling the styrene adhesive to 40-45 DEG C; and adding an enhancer, further heating to 60 DEG C, extruding by an extruding machine, and cooling and molding. The stretch-proof composite belt is excellent in property, low in price, wide in application, good in stability, high in water resistance, high in bonding strength and high in practicability; the tensile strength of the belt is effectively improved; a rupture is reduced; especially, the tensile strength at the bent part is enhanced; and the service lifetime is prolonged.

Description

Technical field: [0001] The invention relates to a method for preparing a belt, in particular to a method for preparing a stretch-resistant composite belt. Background technique: [0002] Belts, also known as conveyor belts, belt conveyors are widely used in agriculture, industrial and mining enterprises, and transportation industries to convey various solid block and powder materials or finished items. The conveyor belt can be continuous, high efficiency, and large inclination. Transportation, the conveyor belt is safe to operate, the conveyor belt is easy to use, easy to maintain, low freight, and can shorten the transportation distance, reduce the project cost, and save manpower and material resources. [0003] The existing belts are all sleeved on the pulleys, tightened, and rotated by friction. Under the tightened state, it is easy to find breakage at the bends, which affects the use, has a short service life and high replacement costs. Summary of the invention: [0004] The te...
