Abstract

Description
Technical Field
The invention relates to the technical field of production of heating radiators, in particular to a heat conduction material capable of being tightly compounded with an aluminum wing tube.
Background
At present, most radiators for hydrophily heating are made of metal materials such as iron, steel, aluminum, copper and the like, and have the problems of easy corrosion, easy scaling, high energy consumption, large pollution and the like. Although plastic-aluminum composite radiators are also on the market, the plastic pipes are used as inner-layer water channels of the radiators, and the aluminum alloy wing pipes are used as radiating terminal parts, the problems of corrosion, scaling, high energy consumption and high pollution of pure metal radiators are solved, the inner-layer plastic pipes and the aluminum alloy wing pipes are difficult to be tightly compounded, and the plastic pipes and the aluminum alloy wing pipes are layered along with expansion and contraction of materials in heating work, so that the radiating performance of the radiators is seriously reduced. For example, a plastic pipe disclosed in the prior patent (application No. 201010001190.0) is injection molded, the length specification of the plastic pipe is limited by a plastic mold, and a vertical pipe with a length of more than 1 meter can be bent and deformed after being demolded, so that the vertical pipe is seriously deviated from the wall, and the product quality is influenced. In the technology disclosed in another patent (application number: 201110047424.X), although pipe extrusion is adopted, the material contains a large amount of graphite, a large amount of water can be absorbed in the granulation process or storage process, and the material cannot be dried by a drying hopper of a pipe extruder, and the pipe directly extruded from the material generates a large amount of air holes, so that the heat-conducting property of the material is influenced, the pressure-bearing property of the pipe is reduced, and the pipe cannot be used for a long time.
Disclosure of Invention
In order to solve the problems, the invention provides a heat conduction material capable of being tightly compounded with an aluminum wing tube, which comprises the following components in parts by weight:
a method for preparing a heat conduction material capable of being tightly compounded with an aluminum wing tube comprises the following steps:
s1: placing polypropylene, graphite, carbon fiber, acrylic acid, dicumyl peroxide, dimethylacetamide and antioxidant into an internal mixer, mixing until the temperature is 100-150 ℃, stopping heating and continuing mixing for 10 minutes;
s2: putting the mixture into a double-screw granulator, setting the temperature of one to ten sections of the double-screw granulator to 240 ℃, 200 ℃, 195 ℃, 190 ℃, 185 ℃ and 180 ℃, controlling the temperature of a machine head to 235-250 ℃, cooling the extruded strip material by a water tank, drying the strip material by a fan, and cutting the strip material into granules;
s3: before the granules are used for preparing the pipe, the granules are stirred by a high-speed stirrer and heated to 95-115 ℃, and the moisture is fully removed, so that the problem that a drying oven hopper of a pipe extruder cannot remove the moisture is solved;
s4: the particles after the moisture removal can be placed into a tube extruder to extrude a tube without cooling, and the particles are stirred again to remove the moisture after being cooled for 24 hours;
s5: when the pipe is extruded, the temperature of the extruder host machine is controlled at 170 ℃, 180 ℃, 190 ℃ and 195 ℃ in one to four sections, the temperature of the die is controlled at 195 ℃, 185 ℃, 175 ℃ and 170 ℃ in one to four sections, and the temperature of the neck ring die is controlled at 170 ℃;
s6: extruding the raw materials through an oral die, entering a sizing sleeve for vacuum sizing, spraying and cooling, setting the traction speed to be 5 m/min, and cutting the length to be 2-4 m.
The invention has the following beneficial effects: the combined action of acrylic acid, dicumyl peroxide and dimethylacetamide increases the viscosity and ductility of the random copolymerization polypropylene, so that the polypropylene is bonded with metal such as metal steel, copper and aluminum, and the pipe has the bonding performance with the aluminum alloy wing pipe; the aluminum alloy can protect the heat-conducting plastic pipe from being damaged by external force, so that the bottleneck that the metal heating radiator cannot be used for a long time due to complex acid-base components of domestic heating water is broken through, and the problem that the heat-conducting performance of a water channel and an aluminum wing pipe of the composite heating radiator is easy to layer is solved.
