Abstract
The invention provides a modified heat conducting plastics which is light, corrosion resistant and high temperature resistant, has long service life and takes nylon graphite as a main body. Columnar or column airfoil plastic radiators with multiple shapes can be prepared by the material.
Description
Technical field
The present invention relates to a kind of hot water that is applied to is that the heating of heating agent is with the plastic tank radiators in fields such as scatterer, interchanger and the preparation method of material and scatterer thereof.
Background technology
How existing heating makes with various metallic substance with scatterer, energy consumption is big, have cost height, complicated process of preparation, easily be corroded, the scatterer of aluminum and steel the current thumping majority heating system following life-span of working conditions of China all about 5 years, do not meet the scatterer industry council of the Ministry of Construction Eleventh Five-Year Plan requirement requirement in 15 year work-ing life.In recent years, also there is the heating for preparing with modified polypropene individually to report with devices such as scatterers.
Summary of the invention
The objective of the invention is to overcome the shortcoming that existing heating radiator is difficult to overcome, the heat-conducting plastic of modifications such as a kind of body is light, corrosion-resistant, high temperature resistant, long service life, nylon graphite is provided, utilizes this material preparation various post aerofoil profile plastic tank radiators or columnar radiators and preparation method.
Plastic tank radiators structure of the present invention.The scatterer single injection-molded is closed type structure, and two flank faces are the plane, and the centre has two posts or three post Φ 25-Φ 45 to hold water channel and connects, and holds the water channel wall thickness at the 2-4 millimeter, decides by holding the water channel diameter.Holding water channel center opposite side has distributing fin, and advantage is the air passageways that two side planes and fin form natural convection, utilizes chimneyeffect to strengthen the heat exchange effect.After being injection molded into one-column radiator, with similar Plastic cap shutoff bottom die core-drawing hole, complete one-column radiator has the Combination Welding machine to form the scatterer of specification requirement again.Just become the massive plate face during each column combination, improve ornamental and be convenient to and clean.Because 215 ℃-250 ℃ of the heat-drawn wires (0.45MPa) of the graphite modified heat-conducting plastic of nylon, it is low because of the thermal change temperature to have solved the modified polypropene scatterer, can only spray the defective of liquid coating at present.Nylon graphite heat conducting plastic tank radiators of the present invention can electrostatic spraying powder coating, has further solved the environmental issue in the spraying.
Modification heat-conducting plastics such as modification of nylon graphite of the present invention are to fill thermally conductive material and auxiliary agent, concrete composition and content (in parts by weight) in the major ingredient of nylon PA6, PA66.
PA6,100 parts of PA66 nylon, the natural high-carbon crystalline flake graphite of 5-20 μ m 20-50 part, expanded graphite 15-40 part, carbon fiber 3-10 part, KH-550 silane coupling agent 2-8 part, 1010 oxidation inhibitor 2-5 parts.Coupling agent also can use aluminate coupling agent and titanate coupling agent.
The method for preparing this kind nylon graphite heat conducting plastics is: required nylon PA6, nylon PA66, natural flake graphite and expanded graphite, carbon fiber, coupling agent, oxidation inhibitor to X (S) M-80 type Banbury mixer (Dalian rubber and plastics machine company limited product) is mixing; deliver to tapered melt forced feed machine toward 44:1SHJ-72 type dual-screw pelletizer by melt feeding lift, earnestly deliver to storage bin (above equipment is all produced by Nanjing chemical machinery company limited of sincere alliance) with high pressure positive blower in the back by the plasticizing head.
Patent of the present invention is compared with the existing heat-conductive composite material of moulding base-material that relates to, and has remarkable advantages, has substantive distinguishing features and obvious improvement:
1, the modification heat-conducting plastics such as nylon graphite of patent of the present invention are selected for use and are moulded base-material, and nylon PA6 and nylon PA66 can be at 100 ℃ of temperature life-time service.
2, nylon PA6 and nylon PA66 are the mobile fabulous bases of moulding in the injection moulding processing, still keep good flowing property after the modification, easily the multiple shape of integral molded plastic scatterer.
3, nylon PA6, PA66 base-material thermal conductivity 0.25W.m-
1.k-
1, and polypropylene PP has only 0.13W.m-
1.k-
1, the base-material thermal conductivity is high about 2 times.
4, in the present invention, one of heat conduction subsidiary material select for use the natural high-carbon crystalline graphite powder of 5-20 μ m and expanded graphite to mix, and have solved the graphite problem that differs greatly of direction thermal conductivity in length and breadth, and nylon graphite heat conducting plastics thermal conductivity reaches 7.25W.m.k after the modification.
5, heat-conducting plastic heat-drawn wire of the present invention (0.45MPa) is 215 ℃-250 ℃, existing market supplying powder coating (electrostatic plastic spraying powder) solidification value is all at 180 ℃, heat-conducting plastic of the present invention can adopt electrostatic plastic spraying, and the plastic tank radiators surface of spraying is the same with the metal heat sink effect.Heat-conducting plastics such as present existing polypropylene all can't solidify under 180 ℃ of temperature, can only spray liquid coating.Heat-conducting plastic of the present invention environmental protection aspect spraying is leading, and cost economizes 2/3rds than the spraying liquid coating.
6, heating plastic tank radiators of the present invention is to stop oxygen or caustic corrosion problem, heat dispersion brilliance, long perfomance life, the new radiator that heating agent water quality severe environment is not had any requirement, can be linked to be overall plastic system with plastic conduit not with oxidation prevention layer, prolong heating system work-ing life greatly, significantly reduce the heating cost.
The present invention prepares heating with scatterer and method at modification heat-conducting plastics such as a kind of nylon graphite.By modification heat-conducting plastics such as nylon graphite of the present invention, pass through a mould two cavity radiating device particular manufacturing crafts more than 430 tons on the injection moulding machine in clamp force, post aerofoil profile or column type heating scatterer are processed in once shaped.The pore of loosing core with similar Plastic cap hot melt shutoff scatterer mould.Complete one-column radiator has the Combination Welding machine to form the scatterer of specification requirement again.Pressing the JG143-2002 standard test implements.
Description of drawings
Synoptic diagram is with post aerofoil profile three posts and to connect scatterer be example:
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, scatterer side-looking, section, look up, front elevational schematic
Fig. 7, scatterer combination front view
Embodiment
With 25kg nylon PA6,10kg nylon PA66, the natural high-carbon graphite powder of 20kg 5 μ m, 10kg20 μ m expanded graphite, 2kg carbon fiber, 1kg KH-550 silane coupling agent, 1kg1010 oxidation inhibitor to the Banbury mixer mixing 8 minutes; deliver to tapered melt forced feed machine toward dual-screw pelletizer granulation, so continuous banburying granulation by melt feeding lift.Again this raw material is put to the injection moulding machine more than the clamp force 4700KN and be injection molded into the scatterer single-column, finally form the scatterer that all size requires by hot melt Combination Welding machine.
