Embodiment 1

[0013] 1) Weigh 5Kg of carbon-plastic fiber, 30Kg of mixed polypropylene, 50Kg of maleic anhydride grafted polypropylene, 5Kg of metallocene polyethylene, 0.2Kg of composite antioxidant, 0.2Kg of light stabilizer and 10Kg of calcium carbonate according to the proportioning ratio. ;

[0014] 2) Put the raw material carbon-plastic fiber, mixed polypropylene, maleic anhydride grafted polypropylene, metallocene polyethylene, composite antioxidant, light stabilizer and calcium carbonate together in a high mixer and stir for 1 to 5 minutes to discharge. ;

[0015] 3) Extrude and granulate the mixed material in a twin-screw machine with a rotation speed of 180-600 rpm and a temperature of 170-240° C. to produce carbon-plastic modified polypropylene plastic particles.

[0016] The carbon-plastic modified polypropylene plastic is blow-molded into a solar water heater water tank liner, and the water tank liner is tested for performance. The test data is as follows:

Abstract

The invention relates to a plastic technology, in particular to a plastic used as an inner chamber of a water tank of a solar water heater. A carbon plastic modified polypropylene plastic comprises 1-10wt% of carbon plastic fiber, 30-50wt% of mixed polypropylene, 30-60wt% of maleic anhydride grafted polypropylene, 3-10wt% of metallocene polyethylene, 0.1-0.3wt% of composite antioxidant, 0.1-0.3wt% of light stabilizer and 10-20wt% of calcium carbonate. The invention solves the problem that the current inner chambers made of stainless steel and enamel can be corroded easily and leak water.

Description

technical field [0001] The invention relates to plastic technology, in particular to a plastic used as an inner tank of a solar water heater. Background technique [0002] At present, the inner tanks of solar water heaters on the market are mostly made of stainless steel and enamel. Stainless steel liner, the manufacturing process is relatively complicated: shearing plate-punching-drum-welding seam-welding various workpieces-insulation layer foaming, but its corrosion resistance, acid and alkali resistance is poor, easy to scale, welding parts are prone to high temperature Oxidation and corrosion will eventually cause water leakage in the water tank until the entire water heater is scrapped. Stainless steel materials have low pressure resistance, are prone to water leakage, poor heat preservation, and short life. The enamel liner is made by coating and burning a layer of inorganic ceramic glaze on the ordinary steel plate. The cost is high, the processing technology is high...
